African health experts warn of climate change & rising vector-borne diseases
- Climate change has become a pressing public health crisis around the world, as disease patterns worsen and emerge in regions where they did not exist before.
- Health experts are particularly concerned about the role of climate change in the rise of vector-borne diseases in Africa’s low- and middle-income countries.
- Rising temperatures can expand and extend the life cycle of disease-carrying vectors such as mosquitoes, ticks and parasites.
- Health experts discussed these issues in a recent webinar organized by the Health Rights Advocacy Forum, the African Medical and Research Foundation and the African Institute for Development Policy.

Warming seas push India’s fishers into distant, and more dangerous, waters
- Many of India’s more than 4 million fishers are sailing beyond the country’s exclusive economic zone into the high seas in search of a better catch.
- Rising sea surface temperatures, overfishing near the shore, and the destruction of reefs have decimated nearshore fisheries, forcing India’s fishers farther out to sea where they face greater risk.
- A common danger they run is straying into the waters of another country, which can lead to their boats being seized and the crew being jailed or even killed.
- The Indian government has issued policies to protect and recover nearshore fish stocks, even as it encourages fishing in the high seas.

In Raja Ampat, pearl farming balances business and ecological sustainability
- In the Raja Ampat islands of eastern Indonesia, pearl farming thrives within a healthy marine ecosystem, with companies like PT Arta Samudra focusing on sustainable practices.
- Pearl farms are very secretive about their methods, which include the delicate process of implanting beads into oysters to cultivate pearls, a technique developed to accelerate pearl production.
- Challenges such as climate change impacts and maintaining a pristine environment highlight the importance of balancing industry growth with ecosystem preservation.
- With concerted efforts to protect marine habitats, Raja Ampat’s pearl industry aims for global recognition while emphasizing sustainability.

Are biodiversity credits just another business-as-usual finance scheme?
- There’s a new emerging innovative finance scheme to support biodiversity conservation: voluntary biodiversity credits. These are meant to be purely voluntary, “positive investment” in nature by the private sector and, in theory, should not be used to offset damage elsewhere.
- But several Indigenous and environmental groups and researchers worry that, like the voluntary carbon credit market, a voluntary biodiversity market could end up being used for offsets, allowing companies and governments to continue business as usual.
- Critics also say there is lack of a clear demand for such credits from the private sector, and a voluntary biodiversity credit market won’t be a sustainable solution at a global scale.
- Indigenous and local communities have the potential to financially benefit from these biodiversity credit projects, which are likely to target their lands. But experts point out the need to first fix several fundamental problems that have already emerged in the carbon credit market, from the lack of land rights among Indigenous communities to unscrupulous middlemen, unjust contracts and dilution of funds.

Oman’s mountain oases offer ancient farming lessons for a warming future
- Traditional oasis agriculture in Oman’s northern mountains is an outstanding example of sustainable land-use in dryland ecosystems.
- But major socioeconomic development throughout Oman over the past 50 years means that traditional agricultural practices, more than a millennium old, are changing too.
- Climate change is also affecting the types of crops that can be grown, particularly at higher altitudes.
- The high value of traditional agricultural products, agritourism, and new cash crops offer ideas on how to sustain the economic viability of these mountain oases.

Planetary boundary pioneer Johan Rockström awarded 2024 Tyler Prize
- The 2024 Tyler Prize for Environmental Achievement will go to Johan Rockström who led the team of international researchers who originated the planetary boundary framework in 2009.
- The theory defines a scientifically based “safe operating space for humanity” to safeguard stable Earth conditions established in the Holocene when civilization arose, with the intention of preventing dangerous tipping points in the Anthropocene — a new era in which humanity has the capacity to wreak havoc on Earth systems.
- In a new interview with Mongabay, Rockström discusses how the planetary boundaries framework formulates quantified safe limits to protect nine Earth systems (including climate, biodiversity, freshwater and more), all vital for sustaining life and he shares some updates on this cutting-edge research.
- “Planetary sustainability is a security issue because staying within planetary boundaries gives us stable societies, food security, water security and reduces conflicts,” says Rockström. “Placing planetary boundaries at the UN Security Council positions sustainability, climate, biodiversity, water, where it belongs — in security.”

Summit on migratory species sides with science, throws shade on deep-sea mining
- Representatives from 133 member states of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) met in Samarkand, Uzbekistan, from Feb. 12-17 to discuss measures to protect migratory species on a global scale.
- Many decisions at the meeting, known as COP14, focused on the protection of marine species, including the listing of several species in the convention’s appendices, a draft decision on vessel strikes, and an updated resolution on climate change that urges parties to take measures to protect species from future threats.
- The convention also adopted a resolution urging parties not to engage with or support deep-sea mining until more scientific evidence is acquired. This resolution garnered criticism from the secretary-general of the International Seabed Authority (ISA), the U.N.-mandated body that governs deep-sea mining in international waters.
- While attendees say COP14 had many successes, some experts say that more action and resources are required to keeping species from sliding toward extinction.

The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
- Every species of animal and plant that lives or breeds in the Arctic is experiencing dramatic change. As the polar region warms, species endure extreme weather, shrinking and altered habitat, decreased food availability, and competition from invading southern species.
- A wide array of Arctic organisms that rely on sea ice to feed or breed during some or all of their life cycles are threatened by melt: Over the past 40 years, the Arctic Ocean has lost about 75% of its sea ice volume, as measured at the end of the summer melt season. This translates into a loss of sea ice extent and thickness by half on average.
- Researchers note that the rate of change is accelerating at sea and on land. While species can adapt over time, Arctic ecosystem alterations are too rapid for many animals to adapt, making it difficult to guess which species will prevail, which will perish, and where.
- The only thing that could limit future extinctions, researchers say, is to quickly stop burning fossil fuels, the main driver of climate change.

Conservationists aim to save South America’s super tiny wild cat, the guina
- The Americas’ smallest wild cat, the guina (Leopardus guigna), is superbly adapted to its home range in Chile and Argentina. But the region is severely affected by deforestation and increasing human population, putting the cat’s future at risk.
- The increase in people in the guina’s habitat has particularly severe consequences, including roads, fences, fires, cattle and, especially, attacks by dogs. The cats are also hunted by people due to their reputation as chicken killers.
- Conservation experts and authorities agree that solutions to save the guina must include local people. They have turned their attention to the people living outside protected areas to help conserve one of South America’s most endangered cats.
- New, groundbreaking environmental legislation in Chile hopefully will also help the cause of the guina and other species impacted by deforestation.

Bangladeshi farmers eye moringa as a climate and economic solution
- Farmers in Bangladesh are increasingly turning to the fast-growing, drought-resistant moringa (Moringa oleifera) tree, which is indigenous to South Asian nations such as India, Pakistan, Bangladesh and Afghanistan.
- Researchers say moringa is beneficial for human health, as both the leaves and the fruits are rich in nutrients and minerals.
- Researchers also suggest that moringa cultivation could be a part of smart agriculture as climatic patterns change, as the plant can tolerate extreme heat and cold.
- A Bangladeshi entrepreneur has been working to create a social movement and entrepreneurship in moringa cultivation and marketing since 2017; so far, he has engaged some 5,000 farmers in 20 districts of Bangladesh.

Indigenous effort in Bangladesh helps reverse endangered fish’s slide to extinction
- Unchecked logging and quarrying of rocks from streambeds in Bangladesh’s Chittagong Hill Tracts led to springs drying up and populations of putitor mahseer fish, an endangered species, disappearing.
- The situation was worsened by climate change impacts, characterized here by a more intense dry season during which even streams that once ran year-round now dry up.
- A project launched in 2016 and backed by USAID and the UNDP is working with Indigenous communities to reverse this decline, starting with efforts to cut down on logging and quarrying.
- As a result of these efforts, areas where forests have been conserved have seen the flow of springs stabilize and populations of putitor mahseer and other fish revive.

As Sri Lanka floods swell with climate change, so does human-crocodile conflict
- Sri Lanka is among the countries most vulnerable to climate change, with long drought spells, receiving intense rain during a shorter period with a marked increase in flood events.
- During flooding, crocodiles inhabiting rivers tend to reach land and move closer to human settlements, increasing the risk of encounters with people.
- The Nilwala River flows through southern Sri Lanka and recent flood events have increased croc encounters with humans in the Matara district and escalated threats to human safety, resulting in disaster management responses.
- During recent flooding events, no serious incidents linked to crocodiles were reported, but wildlife officials had to chase crocs away from riverbanks, highlighting the need for an immediate and durable solution for the human-crocodile conflict around the Nilwala River area.

Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.

Indigenous Gurung farmers revive climate-resilient millet in Nepal
- Indigenous Gurung farmers in central Nepal are trying to revive the cultivation of an almost-forgotten, drought-resilient crop: foxtail millet.
- This hardy grain was traditionally farmed as a famine crop because it grows at a time of the year when farmers are finished harvesting other crops like rice, maize and wheat.
- With Nepal experiencing increasingly unpredictable changes in weather and droughts that affect their harvests, proponents say local crops like foxtail millet have the potential to help farmers adapt to the changing climate.
- Over the past seven years, organic farming of the crop has seen consistent growth, thanks to the help of a community seed bank.

Indigenous-led coalition calls for moratorium on terrestrial carbon trade
- The Pathways Alliance for Change and Transformation (PACT), a coalition of Indigenous, community and nonprofit organizations, published a paper in September 2023 calling for a moratorium on the forest carbon trade out of concern for the rights of Indigenous peoples and local communities.
- PACT says a pause in selling carbon credits is needed until protections for the land rights of these communities are laid out “explicitly, proactively, and comprehensively.”
- In December at the U.N. climate conference in Dubai, carbon markets experienced a setback after negotiators failed to agree on texts to articles in the 2015 Paris climate agreement meant to guide the carbon trade.

Long-term wildlife impacts at Chornobyl, Fukushima may yield ‘a new ecology’
- The world’s worst nuclear power plant accidents to date, at Chornobyl, Ukraine, in 1986, and Fukushima, Japan in 2011, and the human exclusion zones created around them have given scientists a unique opportunity to study the effects on wildlife of radiation and of reduced pressure from people.
- Chornobyl disaster findings regarding the impacts on exclusion zone organisms vary: Some point to a resurgence of the studied wildlife in the absence of humans, while others indicate radiation negatively impacting certain animal populations.
- Fukushima radiation impacts are statistically harder to detect. But scientists have made similar observation to Chornobyl: Some, but not all, species appear to thrive from reduced human pressure.
- Radioactive contamination moves in ecosystem-specific ways, depending on factors such as water flow. A combination of radioactive contamination and reduced human activity in nuclear exclusion zones may be giving rise to “a new ecology,” with nature overall neither suffering nor thriving, simply different in the impacted areas.

Little achieved for Indigenous groups at U.N. climate summit, delegates say
- At this year’s U.N. climate conference, COP28, Indigenous delegates numbered more than 300, but were left generally disappointed with the outcomes of the event.
- The final agreement had little inclusion of Indigenous rights and excluded an Indigenous representative from sitting on the board of the newly launched loss and damage fund.
- Indigenous groups say two big climate mitigation strategies, the clean energy transition and carbon markets, should include robust protection of Indigenous rights and consent.
- Despite setbacks, Indigenous leaders say they’re working on increasing their presence and influence at the next climate conferences, including upping their numbers to 3,000 delegates, creating a large international Indigenous Commission, and taking part in the summit’s decision-making.

Shining a spotlight on the wide-roaming sand cat ‘king of the desert’
- The sand cat (Felis margarita) is a small, elusive wildcat exquisitely adapted to thrive in the deserts of northern Africa, Southwest and Central Asia — some of the hottest, driest habitat on the planet. These felids are near-impossible to see in the daytime and difficult to track at night. As a result, little is known about the species.
- Despite being challenged by limited resources, two European experts have repeatedly traveled to southern Morocco to study the sand cat. Their efforts, along with the rest of the Sand Cat Sahara Team, have led to the gathering of scientifically robust data that is lifting the lid on the secretive life of this tiny felid.
- The sand cat’s status is listed by the IUCN as “least concern” because there is little evidence to indicate its numbers are declining. But data across regions remain scant. New findings from southern Moroccan sand cat study sites beg for this conclusion to be reassessed, with possibly fewer sand cats existing than past estimates indicate.
- Tracking the sand cat’s changing conservation status is important because that data can indicate changes and trends in the ecologically sensitive environments in which they live. In addition, how they adapt, or fail to adapt, to climate change can give us clues to the resilience of species facing today’s extremes, especially desertification.

Indonesia launches new front in climate campaign focusing on seagrass
- Indonesia has published a road map for seagrass protection and rehabilitation, as part of its efforts to mitigate the impacts of the climate crisis.
- Seagrass meadows are estimated to sequester carbon dioxide from the atmosphere at a much greater rate, hectare for hectare, than even tropical rainforests.
- Indonesia has long been recognized as a crucial country for protecting the underwater flowering plants, as it’s estimated to host at least a tenth of the world’s seagrass meadows.

Fish out of water: North American drought bakes salmon
- An unprecedented drought across much of British Columbia, Canada, and Washington and Oregon, U.S., during the summer and fall months of June through October could have dire impacts on Pacific salmon populations, biologists warn.
- Low water levels in streams and rivers combined with higher water temperatures can kill juvenile salmon and make it difficult for adults to swim upriver to their spawning grounds.
- Experts say relieving other pressures on Pacific salmon and restoring habitat are the best ways to build their resiliency to drought and other impacts of climate change.

Beyond Climate: Fossil fuels rapidly eroding Earth’s ‘safe operating space’
- This exclusive three-part Mongabay mini-series explores how the oil, natural gas and coal industry are destabilizing nine vital Earth systems, which create a “safe operating space” for humanity and other life on the planet.
- The first story in the series examined some of the direct detrimental impacts of fossil fuels, petroleum-based agrochemicals and petrochemicals (such as plastics) on climate change, biodiversity loss, nitrogen pollution of the world’s oceans and other forms of pollution.
- This story looks at the direct and indirect impacts that hydrocarbon production is having as it destabilizes Earth’s freshwater systems; influences rapid land use change; pollutes air, land and water; potentially contributes to ozone layer decay; and ultimately impacts life on Earth.
- Scientists say humanity’s actions — inclusive of burning fossil fuels and producing petrochemical and agrochemical products — has already pushed Earth into the danger zone, overshooting six of nine critical planetary boundaries. Unless we pull back from these violated thresholds, life as we know it is at risk.

Beyond climate: Oil, gas and coal are destabilizing all 9 planetary boundaries
- It’s well known that the fossil fuel industry made the industrial age possible and raised much of humanity’s living standard, while also causing the current climate crisis. Less known is how oil, gas and coal are destabilizing other vital Earth operating systems — impacting every biome. This is Part 1 of a three-part exclusive Mongabay miniseries.
- Scientists warned this year that, of the nine identified planetary boundaries, humanity has now overshot safe levels for six — climate change, biosphere integrity, land system change, novel entities (pollution), biogeochemical flows of nitrogen and freshwater change.
- Fossil fuels, petroleum-based agrochemicals and petrochemicals (including plastics) are now significantly contributing to the destabilization of all nine planetary boundaries, based on the review of numerous scientific studies and on the views expressed by dozens of researchers interviewed by Mongabay for this article.
- According to multiple experts, if humanity doesn’t find alternative energy sources and phase out fossil fuels, agrochemicals and petrochemicals, then their production will continue driving the climate crisis; polluting the atmosphere, water and land; creating deoxygenated kill zones in the world’s oceans; and poisoning wildlife and people.

Betting on biodiversity: Q&A with Superorganism’s Kevin Webb & Tom Quigley
- Superorganism is a newly launched venture capital firm, touted to be the first that’s dedicated to addressing the biodiversity crisis.
- The firm aims to support startups that are developing and deploying technology to prevent biodiversity loss and protect nature.
- The firm’s early portfolio includes companies that are working to tackle extinction drivers and finding solutions that lay at the intersection of biodiversity conservation and climate change mitigation.

Bangladesh survey records invasive alien plants threatening protected forests
- According to a survey, 44 exotic invasive plant species were recorded in five protected forests in Bangladesh. Of them, seven species were found to be harmful, with significant environmental impacts on protected forest areas.
- As a signatory of the Convention on Biological Diversity (CBD), the country is committed to protecting ecosystems and biodiversity of flora and fauna.
- To check the number and reduce the negative impacts of the identified alien invasive plant species on ecology and environment, the government has taken five strategic management plans.

Taking the global pulse of biodiversity monitoring: Q&A with Andrew Gonzalez
- A group of scientists have put forward a proposal to set up a global network that centralizes biodiversity monitoring and facilitates seamless sharing of data.
- The group wants its proposed Global Biodiversity Observing System (GBiOS) to function similarly to the network of local weather monitoring stations across the world, whose data are used to analyze and monitor climate change.
- While the technology being used to monitor biodiversity has become more sophisticated over the years, there still exists a void in getting different communities to work together to address the broader challenges in dealing with the biodiversity crisis.
- “We would not only federate people who are working together more effectively, but also fill many of the gaps in the data that currently exist in the biodiversity field,” Andrew Gonzalez, who is leading the proposal for GBiOS, told Mongabay.

Gone before we know them? Kew’s ‘State of the World’s Plants and Fungi’ report warns of extinctions
- The Royal Botanic Gardens, Kew’s “State of the World’s Plants and Fungi” report assesses our current knowledge of plants and fungal diversity, the threats they face and how to protect them.
- The report warns that many plant and fungal species, 45% of documented flowering plants and half of all analyzed fungi risk extinction (though less than 0.4% of identified fungi have been assessed for extinction to date).
- The report identified 32 plant diversity darkspots, places where plants are highly endemic but severely under-documented, including Colombia, New Guinea and China South-Central.
- Report authors argue that priority conservation areas should consider distinctiveness in plants or “phylogenetic diversity” and found that these hotspots of phylogenetic diversity differ from the traditional biodiversity hotspots approach.

Frogs in the pot: Two in five amphibian species at risk amid climate crisis
- The extinction risk for more than 8,000 amphibian species has significantly increased in the past 18 years, primarily due to climate change impacts, with two in five amphibians now threatened, a new study shows.
- Amphibians are particularly vulnerable because of their permeable skin and specific habitat needs; diseases like the chytrid fungus further threaten their survival.
- Salamanders are the most at risk, with a lethal fungus in Europe posing a significant threat, especially to the diverse salamander population in North America.
- The study emphasizes the importance of global conservation efforts, with habitat protection showing positive results for some species, and highlights the broader context of the ongoing global biodiversity crisis.

Return of the wolf to Nepal’s Himalayas may threaten snow leopards
- The return of wolves to Nepal’s Himalayan region is putting greater pressure on populations of naur, or blue sheep — and by extension on snow leopards, whose main prey is naur.
- New research shows that naur tend to exhibit greater vigilance in areas where both wolves and snow leopards are present, while lowering their guard somewhat when no wolves are around.
- Conservationists say the growing wolf presence threatens snow leopards through direct competition for food and through stressing out, and weakening, naur populations.
- Snow leopards already face pressure from common leopards and tigers, which are moving further uphill in response to both human threats and a changing climate.

Barely making it: A conversation with ‘Eight Bears’ author Gloria Dickie
- Gloria Dickie is an award-winning journalist who has documented the state of the world’s eight remaining bear species in a compelling new book, “Eight Bears: Mythic Past and Imperiled Future.”
- Despite the conservation gains made by iconic bear species like the giant panda and the brown bear, most bear species remain at risk.
- In this podcast conversation, the author shares the context behind why some bear species, such as the Andean bear and the polar bear, which face climate-related threats, are much harder to protect.
- “It’s quite tricky for bears threatened by climate change and not just habitat loss,” she says on this episode.

Super flock of pigeons leaves Nepali researchers asking what happened
- Researchers in Nepal say they still don’t know what was behind a massive flock of some 7,500 woodpigeons observed in the country’s plains last December.
- A recently published study suggests a range of factors, from food availability to predator avoidance, combined to bring together the flock, which was 25 times larger than the biggest flock previously observed here.
- Climate factors may also have played a part, particularly the impact of heavy rains on the birds’ overwintering grounds in Pakistan.
- Researchers say more studies are needed to get to the bottom of the mystery, and plan to watch out for another super flock this coming winter.

Nepali researchers yet again photograph snow leopard, leopard in same place
- Nepali researchers capture images of a snow leopard and a common leopard in the same location in the Gaurishankar Conservation Area, adding to the evidence of habitat overlap between the two species.
- The recently analyzed images were taken by camera traps at an altitude of 4,260 meters (13,976 feet) in January 2023.
- Researchers say that climate change is likely to increase interactions between snow leopards and common leopards, as the latter move northward in search of suitable habitat and prey, encroaching on the territory of the former.
- They also warn that habitat overlap could pose a threat to snow leopards, which are smaller and less agile than common leopards, and call for more long-term data and research to understand the impacts of climate change on both species.

‘Catastrophic breeding failure’ for penguins as Antarctic sea ice vanishes
- Researchers found that a lack of sea ice around Antarctica’s Bellingshausen Sea led to “unprecedented” breeding failure in four of five emperor penguin colonies.
- Sea ice cover in Antarctica has been experiencing record lows, which could spell disaster for the future of this iconic Antarctic species.
- Previous estimates have suggested that if current rates of global warming persist, more than 90% of emperor penguin colonies would be “quasi-extinct by the end of the century.”

From debt to diversity: A journey of rewilding, carbon capture and hope
- Rewilding has transformed an English estate from a debt-ridden, conventional farm to a profitable haven of biodiversity.
- A study also shows that the rewilded farmland at Knepp absorbs more carbon dioxide than conventional farms, providing hope for climate change mitigation and soil restoration.
- The U.K. is transitioning to a new environmental land management framework offering incentives for practices that restore soil health and biodiversity, but private investment is still needed to bridge the funding gap.
- Nature restoration investment mechanisms to attract private investment are being developed using Knepp data and government funding.

Forest campaign group renews charge that carbon credit verification schemes are flawed
- A new assessment conducted by Rainforest Foundation UK raises fresh concerns about the validity of carbon offsetting schemes.
- The campaign group claims that all the leading carbon credit verification schemes have allowed millions of credits to enter the voluntary carbon market which do not accurately represent reductions in greenhouse gas emissions.
- RFUK is calling for a shift in emphasis to measures like global carbon levies and debt relief for poor countries, which it says would address root causes of emissions.
- Verra and several REDD+ project managers told Mongabay RFUK’s analysis is ideologically motivated, insisting that while verifying credits is not perfect, it is producing genuine, positive results.

The circular economy: Sustainable solutions to solve planetary overshoot?
- The current linear production and consumption economic model — labeled by critics as “take-make-waste” — is taking a heavy global environmental toll. The intensive use of primary resources and overconsumption are closely linked to climate change, biodiversity loss, large-scale pollution and land-use change.
- Experts and advocates argue that a circular economy model — revolving around reduced material use, reuse and recycling at its simplest — offers a potential route to achieving zero waste, reversing environmental harm and increasing sustainability of products and supply chains.
- In the absence of a firm definition, many interpretations of the circular economy exist. To be sustainable, circular economy solutions should be underpinned by renewable energy sources, reduction of material extraction, reduced consumption, and the regeneration of nature, according to researchers.
- Caution is needed, warn some, as not every circular solution is sustainable. Other experts state that to achieve its goals, the circular economy must include societal level change and go far beyond simply recycling or improving supply chains. How this economic model works will also look differently for nations across the globe.

Genetically engineered trees stoke climate hope — and environmental fears
- U.S. climate technology startup Living Carbon has been developing genetically engineered poplar trees that it says can absorb more carbon – a potential tool in the climate crisis.
- Some experts say the company lacks long-term field data and is rushing to commercialize its “supertrees,” potentially putting other species at risk.
- Despite such concerns, Living Carbon is going ahead and planting mixed forests that include its GE trees, funded by carbon offsets.

‘What we need to protect and why’: 20-year Amazon research hints at fate of tropics
- In its bold outlines, many informed people understand that climate change is reducing tropical biodiversity and thereby degrading the functionality and ecoservices of tropical forests. But what are the specific mechanisms by which these forests are being diminished over long time frames?
- One project on the slopes of the Peruvian Amazon has tried to make exactly that type of assessment, via a 20-year ongoing research project that meticulously observes a narrow transect of rainforest stretching from the Amazon lowlands near sea level to the Andean highlands above 3,352 meters (11,000 feet).
- The international team conducting this work, the Andes Biodiversity and Ecosystem Research Group (ABERG), is painstakingly observing changes in more than 1,000 tree species, birds, frogs, snakes and more to determine not only how much climate change is affecting them, but untangling how the change process works.
- This type of in-depth research is vital to conserving tropical rainforest diversity, the carbon storage capacity it offers, and its assistance in maintaining long-persisting regional and global precipitation patterns vital to agriculture and other water needs. Mongabay contributor Justin Catanoso traveled to Peru to observe ABERG at work.

Big potential and immense challenges for great ape conservation in the Congo Basin, experts say
- Great apes are on track to lose 94% of their range to climate change by 2050 if humans do nothing to address the problem, according to research.
- In the great apes stronghold of the Congo Basin, national interests in natural resource exploitation, a lack of security in areas like the Albertine Rift, hunting, and the illegal wildlife trade all greatly impact populations of bonobos and mountain gorillas.
- In this episode of Mongabay Explores, Gladys Kalema-Zikusoka, Kirsty Graham, Terese Hart, and Sally Coxe speak with Mongabay about the threats to bonobos and mountain gorillas, the lessons learned from decades of conservation efforts, the importance of great apes for the protection of Congo Basin rainforest, and ways forward for conservation as well as livelihoods for Indigenous and local communities.

Microbes play leading role in soil carbon capture, study shows
- Soil is a significant carbon reservoir, storing more carbon than all plants, animals and the atmosphere combined, making it crucial for addressing the climate crisis.
- Microbes, such as bacteria and fungi, are the primary drivers of carbon storage in soil, surpassing other soil processes by a factor of four, according to a new study in Nature.
- The efficiency of microbial metabolism plays a vital role in determining the amount of organic carbon stored in soils worldwide, according to the research, which also calls for improved soil carbon models for effective policies and climate solutions.
- Enhancing microbial efficiency can lead to increased carbon storage in soils, but further research is needed to understand how to achieve this.

Bangladesh’s new red list of plants shows country has already lost seven species
- Bangladesh’s first-ever red list of plant species shows the country has lost seven species in the last century and now risks losing at least another five.
- Researchers involved in the assessments of the conservation status of 1,000 species cited climate change, pollution, deforestation, and poor management of protected areas as major drivers behind the ecological damage.
- The Bangladesh Forest Department is working to protect native plant species through large-scale planting efforts across the country.

For Central America, climate bill could top hundreds of billions annually
- Climate change impacts on Central America’s forests could cost the region between $51 billion and $314 billion per year by 2100, according to a new study.
- For some of the countries in region, the loss of ecosystem services provided by forests could lead to losses equivalent to more than three times their GDP.
- This is the first time ecological and economic measurements have been assessed together for climate change impacts in Central America and could help to inform conservation activities like defining protected areas, establishing biological corridors and restoring degraded landscapes.
- While the impacts of climate change are being felt by communities in the region, breakthroughs in computing power as well as collaborations between European universities and Central American research institutions and companies is promoting increased innovation in ecosystem restoration.

Climate change, human pressures push Bangladesh’s ‘national fish’ into decline
- Bangladesh’s all-important hilsa fishery is declining amid pressures from human-driven factors and climate change, experts and authorities warn.
- The fish, Tenualosa ilisha, contributes around 12% of the total fish catch in Bangladesh, and the fishery employs at least 2.5 million people across the country.
- Several government conservation initiatives, including declaring six hilsa sanctuaries and two fishing bans during the year, have helped boost production in the past two decades.
- However, pressures persist, including rising salinity levels in the rivers where the fish spawn, discharge of pollution and agricultural runoff, and disruptions to water flow as dams are built upstream.

Southern African caterpillar that feeds millions may be next climate casualty
- A new study projects a significant loss of habitat for an edible caterpillar, known as the mopane worm, in Southern Africa in the coming decades.
- Mopane worms are a key source of seasonal protein for millions of people throughout Southern Africa, but they also face pressures from overharvesting and deforestation.
- Species distribution models devised by a group of scientists project that even under a moderate climate change scenario, some regions will lose 99% of suitable habitat for the caterpillars.
- The scientists behind the study say their projections should be seen as a call to protect regional food security by preventing both climate change and biodiversity loss.

Mycorrhizal fungi hold CO2 equivalent to a third of global fossil fuel emissions
- A recent study estimates that more than 13 billion metric tons of CO2 from terrestrial plants are passed on to mycorrhizal fungi each year, equivalent to about 36% of global fossil fuel emissions.
- The study highlights the overlooked role of mycorrhizal fungi in storing and transporting carbon underground through their extensive fungal networks
- Researchers analyzed nearly 200 data sets from various studies that traced carbon flow and found that plants allocate between 1% and 13% of their carbon to mycorrhizal fungi.
- Understanding the role of mycorrhizal fungi is essential for conservation and restoration efforts, as soil degradation and the disruption of soil communities pose significant threats to ecosystems and plant productivity.

Climate warming alters offspring production of birds, study shows
- A global meta-study investigating the effects of climate change on bird reproduction has found an overall decline in annual offspring production over 50 years.
- Offspring production in migratory and large birds decreased, whereas it increased in smaller-bodied and sedentary species.
- Migratory species may find it difficult to adapt to a rapidly changing climate in their breeding and wintering areas. Large birds may have problems adapting to changing climate conditions because they tend to live a ‘slower pace of life’ and have offspring only once a year.
- Curbing our carbon dioxide emissions will halt rising temperatures impacting bird species, say the study’s authors. People can also help boost bird reproduction by creating a cooler environment for bird nests in yards and parks through dense vegetation during heat waves.

Africa’s land and forest restoration initiative gathers pace in Malawi
- In 2015, African countries launched the African Forest Landscape Restoration Initiative (AFR100), committing to restore 100 million hectares (250 million acres) of degraded forests and landscapes by 2030.
- A June 2022 progress report on the initiative showed that nations had put 917,014 hectares (2.27 million acres) under restoration between 2016 and 2021, 63% of that as agroforestry.
- Malawi, which has committed to restoring 4.5 million hectares (11.1 million acres) by 2030, is seen to be making progress with a raft of frameworks formulated to support the initiative and more partners joining the cause, building on some previous interventions.
- Experts insist there needs to be decisive action to tackle deforestation, which they say is a significant threat to the restoration initiatives in Malawi.

Soil carbon in urban parks important in fighting climate change, study shows
- A recent study shows that urban parks and green spaces throughout the world have a similar amount of carbon stored in their soils as in natural regions close to cities, which means urban green spaces can be important to global carbon sequestration and mitigating the potential effects of climate change.
- Soil microbes in urban green spaces play a vital role in carbon storage, but that carbon is also vulnerable to loss through microbial respiration in an increasingly warmer world; researchers emphasize the need for greater understanding of the soil microbiome in urban policies and planning.
- For context, Suriname has 93% forest cover nationwide and is often referred to as the world’s “greenest” country — but the capital city, Paramaribo, lacks a structural approach to urban greenery.
- Researchers conducted a project to promote a greener and more livable Paramaribo, with the aim of mitigating the effects of climate change and raising awareness among citizens.

Head of Verra, top carbon credit certifier, to leave in June
- David Antonioli is the founding CEO of Verra, the world’s most prominent carbon credit standards organization.
- Antonioli will leave the post in June amid increasing scrutiny of carbon markets and credits, as well as the methodologies by which they are certified to ensure they provide climate benefits that do not come at the expense of communities.
- Indigenous groups and forest communities are often key participants in restoration and protection efforts to boost carbon sequestration.
- But they say that little of the financing for climate mitigation flows directly to them, and they also want a more prominent role in the discussions about climate change mitigation projects and the future of mechanisms like carbon credits and markets.

Climate change is no joke for Australians, says award-winning comedian Dan Ilic
- Despite citizens voting out the Scott Morrison-led government of Australia in 2022, Dan Ilic says there’s still a lot of talk around climate change policy with not enough action to meet national climate targets.
- Known widely for his epic billboards appearing in New York’s Times Square during the COP26 climate summit satirizing Australia’s lack of seriousness at the conference, Ilic is host of the award-winning Australian comedy/climate-focused podcast “A Rational Fear” and spoke with the Mongabay Newscast in Sydney about the landscape surrounding climate policy in the country today.
- He also shares his thoughts on victories for Indigenous communities in the Tiwi Islands and the Galilee Basin, both in Australia, where massive fossil fuel proposals were recently blocked.

Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.

An Asian grass helps Mexican farmers build resilience to climate change
- A longtime ingredient in fragrances, vetiver is becoming an ally for farmers facing the impacts of climate change.
- Planting vetiver grass in tropical and subtropical regions is a cheap and simple way to prevent soil erosion, capture carbon dioxide and detoxify the soil, with this nature-based solution already in use for decades in India and now becoming increasingly popular elsewhere.
- In Mexico, where 76% of the land suffers from erosion, one environmental expert in Veracruz state has become a pioneer in using vetiver to stop soil erosion.
- The method used on a tobacco farm helped reduce crop loss and improve harvests significantly in just its first year of implementation.

Overlooked and underfoot, mosses play a mighty role for climate and soil
- Mosses cover a China-size area of the globe and have a significant impact on ecosystems and climate change, according to a new study.
- Researchers conducted the most comprehensive global field study of mosses to date to quantify how soil moss influences soil and ecosystem services in different environments on all seven continents.
- Soil mosses can potentially add 6.43 billion metric tons of carbon to the soil globally, an amount equivalent to the annual emissions of 2.68 billion cars.
- Moss-covered soil offers several other benefits, including cycling of essential nutrients, facilitating faster decomposition, and reducing harmful plant pathogens.

Indigenous groups voice support for REDD+, despite flaws
- A letter published May 9 and signed by a group of Indigenous-led organizations backs a mechanism for providing compensation in return for forest protection efforts known as REDD+, which is short for “reducing emissions from deforestation and forest degradation.”
- The aim of REDD+ is to provide results-based funding for economic development tied to those protection efforts, with financing coming from credits sold to companies and individuals to account for their carbon emissions.
- But critics question how carbon credits are calculated, and others have concerns about the lack of consent and participation by Indigenous and local communities most affected by REDD+ work.
- The letter argues that REDD+, in despite its shortcomings, is one of the few direct funding flows to communities for climate-related work, and they call for greater inclusion in the broader conversation about REDD+ and carbon credits and offsets.

Ground-nesting chimps hold lessons for conservation — and for human evolution
- Eastern chimpanzees in the northern Democratic Republic of Congo frequently build nests and sleep overnight on the ground even in areas where predators are present, a recent study finds.
- The ability of these relatively small-bodied apes to sleep on the ground without fire or fortifications suggests that other hominids, including early humans, could have moved from the safety of trees earlier than thought.
- The study also found that chimpanzees were not deterred from ground nesting when they shared space with humans — as long as those humans were not hunting.
- This, the researchers say, suggests chimpanzee conservation and human use of forests can coexist.

Saving forests to protect coastal ecosystems: Japan sets historic example
- For hundreds of years, the island nation of Japan has seen various examples of efforts to conserve its coastal ecosystems, vital to its fisheries.
- An 1897 law created protection forests to conserve a variety of ecosystem services. “Fish forests,” one type of protection forest, conserve watershed woodlands and offer benefits to coastal fisheries, including shade, soil erosion reduction, and the provision of nutrients.
- Beginning in the late 1980s, fishers across Japan started planting trees in coastal watersheds that feed into their fishing grounds, helping launch the nation’s environmental movement. Although the fishers felt from experience that healthy forests contribute to healthy seas, science for many years offered little evidence.
- New research using environmental DNA metabarcoding analysis confirms that greater forest cover in Japan’s watersheds contributes to a greater number of vulnerable coastal fish species. Lessons learned via Japan’s protection and fish forests could benefit nations the world over as the environmental crisis deepens.

Could biodiversity be a key to better forest carbon storage in Europe?
- A new project is reintroducing key species into Europe’s forests to help restore natural balance and boost the ability of woodlands to store carbon. But there are concerns that unless such reintroductions are made on a much wider, landscape scale, they will have little positive impact in a region so dominated by humans.
- Others argue that the best way to improve Europe’s carbon storage potential is via heavy forest management, even going so far as to clear-cut some older stands and replace them with fast-growing new forests to encourage rapid carbon uptake, and using thinnings from timber operations to burn as biomass to make energy.
- This heavy management approach has raised deep concerns within the scientific community. Many researchers say this method ignores the growing body of evidence that plantation forest monocultures are not only bad for biodiversity and store less carbon, but also increase the risk of spreading devastating diseases.
- A middle ground could see more natural management of some forests where timber is harvested, while other woodland areas are left undisturbed, with a mixture of tree species, deadwood allowed to rot where it falls, and native animals reintroduced to help restore a natural balance and healthy ecosystems.

A caribou hunter and researchers uncover the impact of climate change on Arctic hunting
- Indigenous communities in the Alaskan and Canadian Arctic have relied on the migratory Porcupine caribou herd for thousands of years, leading to a deep relationship and respect for the caribou.
- A study found that decreased snowfall, driven by climate change, could make it more difficult for Indigenous communities to travel on snow mobiles to hunt for caribou.
- The study was a collaboration between Indigenous and non-Indigenous researchers who analyzed a rare log of Indigenous knowledge, surveys that hunters completed annually.

Rewilding animals could be key for climate: Report
- A new report published in Nature Climate Change suggests that trophic rewilding, or restoring and protecting the functional roles of animals in ecosystems, is an overlooked climate solution.
- Reintroducing just nine species or groups of species (including African forest elephants, American bison, fish, gray wolves, musk oxen, sea otters, sharks, whales and wildebeest) would help limit global warming to less than the 1.5°C (2.7°F) threshold set by the Paris Agreement, according to the report.
- Animals play a significant role in how much carbon plants, soil and sediments can capture, as they redistribute seeds and nutrients and disturb soil through digging, trampling, and nest-building.
- The report emphasizes the need for a change in mindset within science and policy to take advantage of the vast potential of wildlife, while working closely with local communities to address social issues that can affect conservation efforts.

In Calakmul, water troughs offer possible solution to human-wildlife conflict
- Beekeepers near the Calakmul Biosphere Reserve are working with conservationists to provide water troughs for wild animals in an effort to reduce conflicts with farmers and livestock.
- More than 70 species, including Baird’s tapir, jaguars (Panthera onca), ocelots (Leopardus pardalis) and coatis (genus Nasua), have used the troughs as climate change exacerbates water shortages in the biosphere during the dry season.
- Conservationists caution that such projects must be implemented carefully so as not to introduce pathogens into the wild or create “predator traps” where wild carnivores’ prey congregate around artificial water sources.

DRC’s endangered bonobos face another threat to their survival: malaria
- Along with humans, great apes like gorillas and chimpanzees are known to get infected with malaria, but evidence about the parasite’s effects on bonobos has been scant.
- A recent study that analyzed the feces of bonobo across the species’ range found that one bonobo population showed evidence of both malaria infection and a genetic variation that would likely protect them against severe disease.
- This genetic variation was less common in other populations, suggesting that other bonobo groups could be in trouble if climate change brings malaria-carrying mosquitoes into their habitats.

Can we fix our failing food systems? Agroecology has answers
- The U.S. has an industrialized and unsustainable food system that depletes non-renewable resources such as groundwater and soil, and this model has been exported widely around the world, a top agriculture author explains on this episode of the Mongabay Newscast.
- Two regions where these impacts and depletion are being felt most are in California’s Central Valley and on America’s Great Plains.
- Consistent overproduction of commodities such as soy, milk and corn under an agribusiness model that pursues constant profits despite a local lack of demand exacerbates the problem, says Johns Hopkins Center for a Livable Future research associate Tom Philpott.
- An author and former food journalist for Mother Jones and Grist, Philpott joins the podcast to talk about these acute problems and what can be done to reform unsustainable food systems with practices like agroecology.

A liquid biofuels primer: Carbon-cutting hopes vs. real-world impacts
- Liquid biofuels are routinely included in national policy pathways to cut carbon emissions and transition to “net-zero.” Biofuels are particularly tasked with reducing emissions from “hard-to-decarbonize” sectors, such as aviation.
- Three generations of biofuel sources — corn, soy, palm oil, organic waste, grasses and other perennial cellulose crops, algae, and more — have been funded, researched and tested as avenues to viable low-carbon liquid fuels. But technological and upscaling challenges have repeatedly frustrated their widespread use.
- Producing biofuels can do major environmental harm, including deforestation and biodiversity loss due to needed cropland expansion, with biofuel crops sometimes displacing important food crops, say critics. In some instances, land use change for biofuels can add to carbon emissions rather than curbing them.
- Some experts suggest that the holy grail of an efficient biofuel is still obtainable, with much to be learned from past experiments. Others say we would be better off abandoning this techno fix, investing instead in electrifying the transportation grid to save energy, and rewilding former biofuel croplands to store more carbon.

Cultural heritage is an essential resource for climate change science too, reports say
- Four reports by the International Co-Sponsored Meeting on Culture, Heritage and Climate Change highlight that human cultural heritage has a wealth of knowledge to contribute to grapple with climate change.
- The reports also say that this diverse human heritage is under threat from climate change, poverty, rapid urbanization, policy, and failure to recognize land rights or grant access to resources.
- The authors share a list of cultural practices and knowledge systems that can mitigate and adapt to the impacts of climate change, from food systems and forest conservation to architecture and natural resources management.
- The International Co-Sponsored Meeting on Culture, Heritage and Climate Change reports are co-sponsored by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), UNESCO and ICOMOS.

As Himalayas thaw, snow leopards scramble for habitat: Q&A with Bikram Shrestha
- Snow leopards face a severe prospect of both a shrinking range and fragmented populations as climate change makes their Himalayan homeland less hospitable.
- Bikram Shrestha is a leading snow leopard researcher in Nepal, where he says it’s possible there may not be habitable space for the big cat as temperatures rise.
- He says a key action to conserving snow leopards is to ensure a plentiful supply of prey species, which means ensuring there’s enough suitable habitat for species like Himalayan tahrs and martens.
- Shrestha spoke with Mongabay’s Abhaya Raj Joshi about the need for more research into the world’s most elusive big cat, the prospect of conflict with humans, and why some locals want snow leopards killed.

Scientists map nearly 10 billion trees, stored carbon, in Africa’s drylands
- A recent study has mapped the locations of 9.9 billion trees across Africa’s drylands, a region below the Sahara Desert and north of the equator.
- The research, which combined satellite mapping, machine learning and field measurements, led to an estimate of 840 million metric tons of carbon contained in the trees.
- This figure is much lower than the amount of carbon held in Africa’s tropical rainforests.
- However, these trees provide critical biodiversity habitat and help boost agricultural productivity, and this method provides a tool to track both degradation and tree-planting efforts in the region.

Climate change is exacerbating human-wildlife conflict, but solutions await: Study
- A review of 49 studies reveals that a variety of weather-related phenomena that are likely to become increasingly common due to climate change may increase human-wildlife conflict.
- The most commonly reported conflict outcomes were injury or death in people (43% of studies) and wildlife (45% of studies), and loss of crops or livestock (45% of studies). Many documented cases are occurring in the tropics, with animals such as Baird’s tapir (Tapirus bairdii) in Mexico, and elephants in Africa and Asia, increasingly coming into conflict with local communities.
- The impacts of climate change on human-wildlife conflict may especially affect vulnerable human populations, particularly when combined with pressures that limit mobility and flexibility in humans and animals. These stressors should be minimized where possible, researchers suggest.
- A better understanding of the climatic drivers of human-wildlife conflict could help prevent or alleviate conflicts. Predicting the onset of extreme weather events such as droughts, and proactively responding with temporary measures to protect animals and people, could be one effective solution, as could sharing information on how to avoid the hazards of wildlife conflict.

Himalayan catfight looms as tigers, leopards venture into snow leopard land
- A warming climate threatens to push Nepal’s three big cat species — tigers, leopards and snow leopards — into closer proximity to each other, with unknown consequences for the survival of each.
- Conventional wisdom says tigers prevail in the country’s southern plains, leopards in the mid-country hill region, and snow leopards in the Himalayas.
- But both tigers and leopards have been observed at elevations above 3,000 meters (9,800 feet), well within snow leopard territory, although conservationists say tigers are less likely to persist at these altitudes over the long term.
- A complicating factor is the role of humans, with human settlements also moving up in altitude in search of more suitable conditions, and putting all four apex species in direct competition.

Machine learning makes long-term, expansive reef monitoring possible
- Conservationists can now monitor climate impacts to expansive marine ecosystems over extended periods of time, a task that used to be impossible, using a tool developed by scientists in the U.S.
- The machine learning tool, called Delta Maps, provides a new way to assess which reefs might be best suited for survival, and which play a key role in delivering larvae to others, and therefore should be targeted for preservation efforts, according to the scientists.
- The scientists used the tool to examine the impacts of climate change on connectivity and biodiversity in the Pacific Ocean’s Coral Triangle, the planet’s most diverse and biologically complex marine ecosystem.
- The authors also noted that the Coral Triangle had more opportunities for rebuilding biodiversity, thanks to the region’s dynamic climate component, than anywhere else on the planet.

Podcast: Goodbye to blue skies? The trouble with engineered solutions
- Humanity has created a lot of ecological problems, and many of the proposed solutions come with giant price tags — or the things lost can even be priceless, like the sight of a blue sky — with no guarantee of solving the situation in the long term.
- Many such solutions — like Australia’s deliberate introduction of the toxic cane toad, which has wreaked havoc on the country’s wildlife — create new problems.
- Solar geoengineering to slow climate change would have the most visible effect to all, likely making the sky appear white: No more blue skies—but how would this affect the global plant community’s ability to photosynthesize, would it harm agriculture?
- Pulitzer Prize-winning author Elizabeth Kolbert joins the Mongabay Newscast to talk about her latest book, “Under a White Sky,” which examines these interventions, the problems they come with and humanity’s seeming inability to stop turning to them.

Updated guide gives practical advice for buyers of tropical forest carbon credits
- An updated guide written by eight conservation and Indigenous organizations offers a detailed path forward for companies that want to compensate for their carbon emissions in addition to decarbonizing their supply chains.
- Though the carbon market faces criticism over the true value it brings to climate change mitigation, proponents say it can complement earnest efforts to decarbonize supply chains if used properly.
- The updated Tropical Forest Credit Integrity guide calls for due diligence on the part of companies to ensure the credits they purchase will result in climate gains.
- The authors of the guide also stress the importance of including Indigenous peoples and local communities in decisions about offset efforts.

Peatland restoration in temperate nations could be carbon storage bonanza
- Much maligned and undervalued over the centuries, temperate peatlands have seen a lot damage in that time — drained for agriculture, planted with trees, mined for horticulture and fuel. But in an age of escalating climate change, people are now turning to restoration.
- As potent carbon sequesters, peatlands have only recently been given new attention, with active restoration taking place in many nations around the world. This story focuses on groundbreaking temperate peatland restoration efforts in the U.S. Southeast, Scotland and Canada.
- Every temperate peatland is different, making each restoration project unique, but the goal is almost always the same: restore the natural hydrology of the peatland so it can maximize carbon storage and native biodiversity, and improve its resilience in the face of climate change and increasingly common fires in a warming world.

With climate change, Nepal’s leopards get a bigger range — and more problems
- Climate change will make higher-elevation areas of Nepal suitable habitat for leopards, a new study shows.
- This is expected to push the big cats into increased conflict with humans and more competition with snow leopards.
- Most of the current and new habitat will fall outside protected areas, and the leopards’ preferred prey may not be available there, which could prompt the predators to hunt livestock.
- But the finding could also be an opportunity to conserve leopards in their potential new habitat, by educating communities there, ensuring availability of wild prey, and drawing up wildlife management plans.

Podcast: Botanists are disappearing at a critical time
- The expansive field of botany could be facing a dearth of skilled experts due to a growing lack of awareness of plants, interest in studying them, and fewer educational opportunities to do so.
- Humans depend upon plants for basic survival needs, such as food, oxygen, and daily household products, but fewer students are receiving enough instruction to enable them to do much beyond basic identification.
- This lack of educational opportunities to study plants – and a general lack of interest in them – is leading to less ‘plant awareness’ and could endanger society’s ability to address existential problems like biodiversity loss and even climate change.
- The University of Leeds’s Sebastian Stroud joins the Mongabay Newscast to talk about his research highlighting this increasing lack of plant literacy, the consequences of it, and what can be done to turn it around.

For threatened seabirds of NE Atlantic, climate change piles on the pressure
- A new report shows that puffins and other seabird species in the Northeast Atlantic are at risk from climate change.
- It warns most seabird species would lose a substantial amount of their current breeding sites and available prey due to climate change, but each species has unique challenges.
- The authors describe potential interventions that conservation experts can enact to protect the species, including the relocation of seabird breeding sites, supplementary feeding, and providing resources that help seabirds deal with extreme weather events such as flooding and heat waves.

Biodiversity, human rights safeguards crucial to nature-based solutions: Critics
- Nature-based solutions (NbS), a hotly debated concept, gained significant political traction throughout 2022, even as challenges and concerns over the failure to implement biodiversity and human rights safeguards in current and future NbS projects have increased among Indigenous peoples and NGOs.
- Recent global policy instruments have recognized NbS, including the Kunming-Montreal Global Biodiversity Framework adopted in December 2022, and the U.N. climate summit cover decision agreed to in November. In March 2022, the U.N. Environment Assembly adopted a multilaterally agreed definition of NbS.
- Despite NbS policy advances, skepticism continues to swirl around the potential for misuse and abuse of nature-based solutions as a greenwashing mechanism by businesses to offset their ongoing carbon emissions, but without curbing them, and as a market mechanism to commodify and put a price tag on nature.
- Experts emphasize that there can be no successful nature-based solutions without the preservation of biodiversity and human rights. Therefore, projects that are a detriment to conservation, and involve monocultures, land grabs or human rights abuses, should be disqualified and rejected for not meeting the NbS definition.

The tiger in the snow: Cameras capture abundance of life in a Himalayan refuge
- Camera traps have captured tigers roaming at an elevation of 3,165 meters (10,384 feet) in eastern Nepal’s lower Himalayas — the highest they’ve ever been recorded in the country.
- Experts suggest a range of factors for this, including a growing tiger population that’s crowding some of the big cats out of the lowland plains and further uphill.
- Another set of camera trap images were captured in Dadeldhura district in western Nepal, which a previous study identified as a climate refugium, where temperatures remain relatively stable, allowing species to persist during regional and global climate changes.
- Other large mammals have also been recorded on camera trap here, including many that, like tigers, were previously thought to be confined to lower-elevation habitats.

Podcast: At COP 15, biodiversity finance, Indigenous rights, and corporate influence
- Mongabay editor Latoya Abulu joins the Mongabay Newscast to discuss her visit to the United Nations conference on biodiversity in Montreal that occurred in December 2022.
- Latoya shares the details on the landmark Kunming-Montreal Biodiversity Framework, which nearly 200 nations agreed to, toward halting and reversing global biodiversity loss by 2030.
- While the historic agreement has been lauded as a victory, particularly for its inclusion of the acknowledgment of Indigenous rights, biodiversity experts, advocates and Indigenous leaders alike have reservations.
- Latoya speaks about all this as well as corporate influence over the final text, such as the inclusion of “biodiversity credits,” which also raise some concerns.

Protecting canids from planet-wide threats offers ecological opportunities
- Five species within the Canidae family are considered endangered. These species, while found far apart in North and South America, Asia and Africa, often share similar threats, including habitat loss, persecution, disease and climate change.
- For some at-risk canid species, loss of prey, particularly due to snaring, is a significant concern that can also exacerbate human-wildlife conflict. Ecosystem-level conservation that protects prey species populations is required to protect canids and other carnivore species, experts say.
- Conservationists and researchers emphasize that canids play important roles in maintaining the habitats in which they live. That makes protecting these predators key to restoring and maintaining functional ecosystems.
- In the face of widespread global biodiversity loss, some canid reintroductions are taking place and proving successful. These rewilding efforts are offering evidence of the importance of canids to healthy ecosystems and to reducing various ecosystem-wide threats, even potentially helping curb climate change.

On climate & biodiversity, where are we, post-COP15? (commentary)
- There are many connections between climate change and biodiversity loss, and many of the actions needed to meet the 2030 action targets around biodiversity loss can also work toward climate change targets.
- One of the things that stood out about the COP27 climate treaty decision text, though, was that it did not reference the subsequent conference on biodiversity – COP15 – hence failing to ‘join up’ the conferences in a meaningful way, a new op-ed argues.
- If we hope to both reduce emissions by at least 45% and put biodiversity on a path to recovery, coherent approaches must be applied, writes Fauna & Flora International’s director of Climate & Nature Linkages.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Extinct sea cow’s underwater engineering legacy lives on today, study finds
- In a new study, scientists said that the extinct Steller’s sea cow impacted kelp forests in the North Pacific by browsing at the surface, which would have encouraged the growth and strengthening of the algal understory.
- Not only would sea cows have positively impacted kelp forests in the past, but they may have also enhanced their resilience into modern times, according to the authors.
- Globally, kelp forests face many threats, including ocean warming, which can lead to an overabundance of predatory urchins.
- The authors suggest that it might be possible for humans to reproduce the species’ impact on the canopy of kelp forests to enhance kelp forest resilience.

Brazil’s Pantanal is at risk of collapse, scientists say
- Though the Pantanal is 93% privately owned, this vast Brazilian tropical wetland remains a stronghold for jaguars and untold other species, and connects animals with the Amazon, Cerrado and other biomes.
- A confluence of human activities in Brazil and worldwide — including deforestation and climate change — are heating and drying this watery landscape, threatening the entire ecosystem with drought, wildfires and habitat loss.
- Now, a plan to dredge and straighten the Paraguay River that feeds the Pantanal could serve as the death knell for this vast wetland ecosystem.
- There’s hope that president-elect Luiz Inácio Lula da Silva, who campaigned on an environmental platform, will initiate stewardship that stops Pantanal deforestation and the waterway project, helping curb greenhouse gas emissions.

Global study reveals widespread salt marsh decline
- The world lost 1,453 square kilometers (561 square miles) of salt marsh between 2000 and 2019, an area twice the size of Singapore, according to a new study based on satellite imagery.
- In addition to providing wildlife habitat and numerous ecosystem services, salt marshes store a great deal of carbon.
- Salt marsh loss resulted in 16.3 teragrams, or 16.3 million metric tons, of carbon emissions per year, according to the study. That’s the rough equivalent of the output of around 3.5 million cars.
- Climate change is one of the greatest threats to marshes. Other contributors to their global decline include conversion to aquaculture, coastal erosion, eutrophication, drainage, mangrove encroachment and invasive species.

Mongabay’s Conservation Potential series investigates: Where do we need to protect biodiversity?
- Leaders and decision-makers are recognizing the urgency of protecting the world’s remaining biodiversity, but investing in conservation requires these actors have access to reliable and actionable information about ongoing conservation projects.
- Mongabay is launching a series of stories called “Conservation Potential,” in which we investigate conservation efforts in high-priority biodiversity areas in tropical forests across the globe.
- To introduce this series, we look at what some experts say about where to prioritize biodiversity conservation, what are some popular approaches to conservation, and what makes conservation projects successful.
- Approaches to conservation vary according to priorities, and there are even debates over what it means to protect biodiversity. This introduction is not meant to be an exhaustive review of the dozens of plans and schemes for preserving biodiversity, but it offers a conceptual starting point for our series.

In Sierra Leone’s fishing villages, a reality check for climate aid
- In April, Mongabay’s Ashoka Mukpo visited the Sherbro estuary, a sprawling riverine ecosystem of mangroves and coastal fishing villages on the Sierra Leonean coastline.
- Like other coastal areas in West Africa, the Sherbro estuary is already suffering the impacts of climate change, including flooding and higher temperatures.
- Between 2016 and 2021, USAID financed mangrove replanting and the construction of makeshift seawalls in villages here as part of a coastal climate resilience aid project.
- The project’s struggles here are an example of the difficulties that climate aid efforts can face when they meet the economic and social needs of people in vulnerable areas.

Counterintuitive: Large wild herbivores may help slow climate change
- Large animals, especially herbivores such as elephants, are often seen as being destructive of vegetation, so are not thought of as a nature-based climate solution. Scientists are proving otherwise.
- By removing living and dead plants, large animals dispose of material that may fuel wildfires, which can add large amounts of carbon to the atmosphere; by consuming vegetation and excreting dung, large animals may improve the availability of nutrients to plants and support the storage of carbon in vegetation and soil.
- By creating gaps in the vegetation and dispersing seeds, large animals create diverse ecosystems with plenty of opportunities for a variety of plants to grow, making ecosystems more resilient and better able to deal with climate change.
- By nibbling down polar region shrubs and trampling snow, large animals help maintain permafrost, helping prevent the release of carbon to the atmosphere.

Threatened cloud forests key to billions of dollars worth of hydropower: Report
- Payments for the provision of water by cloud forests for hydropower could produce income for countries and bolster the case for the forests’ protection, a new report reveals.
- These fog-laden forests occur on tropical mountains, with about 90% found in just 25 countries.
- Cloud forests are threatened by climate change, agricultural expansion, logging and charcoal production, and studies have shown that the quality and quantity of water that these forests generate is tied to keeping them healthy.

Climate change is hammering insects — in the tropics and everywhere else: Scientists
- A new review paper finds that climate change is pounding insects in a wide variety of ways all over the world.
- Because insects are so sensitive to temperature change, climate change is impacting them directly, including potentially decreasing their ability to breed.
- But climate change is also causing insects to change their behavior as it shifts seasonal beginnings and ends, risking that insects will act out of sync with the rest of the environment on which they depend. Climate change-intensified drought, extreme precipitation, lengthening heat waves, and fires are also harming insects.
- The best way to protect insects? Combat climate change and safeguard micro-habitats.

Animating the Carbon Cycle: Earth’s animals vital allies in CO2 storage
- The idea of animating the carbon cycle (ACC) is relatively new. The concept champions the role that healthy populations of wild animals, both terrestrial and marine, can play in boosting the ability of ecosystems to store carbon, helping the planet stay within 1.5°C (2.7°F) of temperature rise over pre-industrial levels.
- But for ACC to be fully effective, humanity needs to preserve and protect intact nature. We also need to rebuild populations of wild animals, including apex predators such as wolves, large herds of herbivores, and invertebrates such as pollinators. By doing so we can help rebalance the functions of natural systems.
- ACC puts the spotlight on oceans too, and the role animals there can play in sequestering carbon. It calls for greater protection of the seas and marine life, allowing whale populations to grow, and protecting mesopelagic fish — the largest group of vertebrates on the planet — from overfishing.
- By looking at the bigger picture of animal-plant-ecosystem relationships, and based on the growing popularity of nature-based climate solutions, scientists believe that now is the time for the wider conservation and rewilding movements to embrace ACC to help animals fulfill their vital roles in the carbon cycle.

Scientists plead for protection of peatlands, the world’s carbon capsules
- As the United Nations Biodiversity Conference begins, a group of researchers from more than a dozen countries are calling for worldwide peatland protection and restoration for the protection of species and because of the vast amounts of carbon they contain.
- In a signed statement released Dec. 1, more than 40 scientists note that peatlands contain twice as much carbon as is found in all the world’s forests.
- As long as peatlands remain waterlogged, that carbon will stay in the soil; but if they’re degraded or drained, as around 12% of the world’s peatlands have been, they quickly become a source of atmospheric carbon.
- The scientists are asking for a more prominent role in international negotiations to address climate change and species’ global loss.

Human justice element is key to stemming biodiversity loss, study says
- In a new paper, a team of scientists argue that efforts to halt biodiversity loss and aid recovery must strive to put both nature and people on a positive path forward.
- According to the scientists, this can be done by confronting the main drivers of biodiversity loss; addressing inequities between low-income and high-income countries; acknowledging unrealistic goals and timelines for conservation actions; and combining area-based conservation efforts with justice measures.
- The paper’s release precedes the start of the COP15 summit of the U.N. Convention on Biological Diversity (CBD), where government representatives, scientists and activists will discuss the post-2020 global biodiversity framework.
- COP15 is set to begin on Dec. 7 in Montreal, with the aim of getting humans to live in harmony with nature by 2050.

Biodiversity credit market must learn from carbon offset mistakes (commentary)
- The nascent biodiversity credit market is beginning to be used to finance measurable and positive outcomes for biodiversity.
- Not to be confused with biodiversity offsets, which compensate for the residual biodiversity impacts of development, credits have been used to conserve habitat for species such as spectacled bears and yellow-eared parrots.
- As the world looks forward to the upcoming biodiversity treaty meeting (COP15) in Montreal, “credits have a chance to learn from the mistakes of their carbon counterparts. It is critical that we get this right from the start,” two credit market CEOs argue in a new op-ed.

Bird declines boost case for transformative biodiversity agreement in Montreal
- A recent report from the conservation partnership BirdLife International reveals that populations of 49% of avian species are decreasing. That figure in the group’s last report, in 2018, was 40%.
- Habitat loss, hunting and fisheries bycatch continue to threaten birds, but newer threats, such as avian flu and climate change, are also endangering the survival of bird species.
- Scientists say the United Nations Biodiversity Conference, which begins in Montreal on Dec. 7, is an opportunity for countries to implement conservation measures, such as protecting 30% of the planet by 2030, to halt the global loss of plant and animal species.

Despite pledges, obstacles stifle community climate and conservation funding
- As science has increasingly shown the importance of conservation led by Indigenous peoples and local communities (IPLCs), donors have begun to steer funding toward supporting the work these groups do.
- In 2021, during last year’s COP26 U.N. climate conference, private and government donors committed $1.7 billion to secure the land rights of Indigenous peoples and local communities.
- But a recent assessment of the first year of the pledge shows that little of the funding goes directly to them, often going first through international NGOs, consultancies, development banks and other intermediaries.
- Most aid intended to support IPLC-led conservation work follows this path. Now, however, donors and IPLC leaders are looking for ways to ease the flow of funding and channel more of it to work that addresses climate change and the global loss of biodiversity.

Myanmar communities decry disempowerment as forest guardians since 2021 coup
- Within the shrinking civic space and violent aftermath of Myanmar’s February 2021 military coup, community-level efforts to safeguard Myanmar’s vast tracts of forest from development are buckling under the pressure of rampant resource extraction.
- Representatives of Indigenous peoples and local communities recently highlighted the challenges facing IPLCs in the country, many of whom have been displaced by conflict and estranged from their ancestral lands and forests.
- Environmental defenders and Indigenous rights activists are among those targeted for arrest and detention by military-backed groups.
- Activists are questioning how the world can seriously address global climate change when environmental defenders are actively being prevented from taking action.

Humans are decimating wildlife, report warns ahead of U.N. biodiversity talks
- Wildlife populations tracked by scientists shrank by nearly 70%, on average, between 1970 and 2018, a recent assessment has found.
- The “Living Planet Report 2022” doesn’t monitor species loss but how much the size of 31,000 distinct populations have changed over time.
- The steepest declines occurred in Latin America and the Caribbean, where wildlife abundance declined by 94%, with freshwater fish, reptiles and amphibians being the worst affected.
- High-level talks under the U.N. Convention on Biological Diversity (CBD) will be held in Canada this December, with representatives from 196 members gathering to decide how to halt biodiversity loss by 2030.

“Largest of its kind” dam in Cameroon faces backlash from unimpressed fishmongers
- Cameroon is constructing a new 420-megawatt capacity hydroelectric dam in Batchenga, aiming to reduce the country’s significant energy deficit by 30%.
- The massive dam project is impacting several villages where fishing is an essential part of the local economy. Several professional bodies, including fishmongers, fishermen and restaurant owners, have lost their livelihoods due to the dam’s construction.
- Fishmongers in one nearby village, Ndji, are becoming increasingly desperate for proper compensation as the amounts paid by the Nachtigal Hydro Power Company is not enough to make ends meet, they say.
- Civil society organizations are also accusing Nachtigal of seriously violating environmental standards during dam construction, despite the company continuously receiving environmental compliance certificates by the government.

On Indigenous Peoples’ Day, five inspirational conservation stories in the U.S.
- Today, people across the U.S. are observing Indigenous Peoples’ Day, juxtaposed against Columbus Day which is celebrated at the same time, to honor Indigenous peoples and their cultures.
- From conserving some of the last old-growth redwood forests in California to halting oil drilling in the Alaska’s arctic, Indigenous tribes see their participation and knowledge as key to bringing solutions to the biodiversity and climate crises.
- To mark Indigenous Peoples’ Day, Mongabay rounds up five of this year’s most inspiring solutions-based stories in the U.S.

Trouble in the tropics: The terrestrial insects of Brazil are in decline
- New research from Brazil shows terrestrial insects there are declining both in abundance and diversity, while aquatic insects are largely staying steady.
- Given a dearth of long-term data on tropical insects, the scientists took creative means to collect data, including contacting 150 experts for their unpublished data.
- Scientists believe the usual global suspects are behind Brazil’s insect decline: habitat destruction, pesticide use, and climate change.
- Experts say tropical countries need more resources, including long-term funding, to discover with greater certainty what’s happening to insects there. Large-scale insect loss threatens many of Earth’s ecological services, including waste recycling, helping to build fertile soils, pollinating plants, and providing prey for numerous other species.

Will the Uinta Basin Railway derail U.S. climate change efforts? (commentary)
- The Uinta Basin is home to a diverse set of creatures from endangered black-footed ferrets to plants that cannot be found anywhere else in the world, such as the Uinta Basin hookless cactus and Graham’s beardtongue.
- But the basin also sits atop pockets of crude oil and natural gas, which are being extracted: to transport these fossil fuels to the Gulf Coast, local governments and oil companies are planning to invest up to $4.5 billion to construct a new railway through it.
- Although the project has been approved, construction hasn’t begun and it’s not too late for U.S. President Biden to keep his climate pledges and stop the new railway, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

U.S. charts course for adopting ropeless fishing to reduce whale deaths
- The National Oceanic and Atmospheric Administration (NOAA) has published a report laying out a strategy to allow the use of “ropeless” or “on-demand” fishing gear off the U.S. East Coast with the goal of reducing entanglements of the critically endangered North Atlantic right whale.
- The gear uses acoustic signals to locate and retrieve gear, reducing the amount of time that vertical lines are present in the water column, where they can ensnare right whales and other types of marine life.
- Right whale numbers in the North Atlantic have declined precipitously in the past decade, as collisions with ships and entanglements have killed individuals and hampered the species’ ability to reproduce.
- NOAA’s Ropeless Roadmap estimates that on-demand fishing gear can substantially diminish the risk to right whales, while allowing economically and culturally important fisheries of the northeastern U.S. to continue.

How close is the Amazon tipping point? Forest loss in the east changes the equation
- Scientists warn that the Amazon is approaching a tipping point beyond which it would begin to transition from a lush tropical forest into a dry, degraded savanna. This point may be reached when 25% of the forest is lost.
- In a newly released report, the Monitoring of the Andean Amazon Project (MAAP) estimates that 13.2% of the original Amazon forest biome has been lost due to deforestation and other causes.
- However, when the map is divided into thirds, it shows that 31% of the eastern Amazon has been lost. Moisture cycles through the forest from east to west, creating up to half of all rainfall across the Amazon. The 31% figure is critical, the report says, “because the tipping point will likely be triggered in the east.”
- Experts say the upcoming elections in Brazil could have dramatic consequences for the Amazon, and to avert the tipping point we must lower emissions, undertake ambitious reforestation projects, and build an economy based on the standing forest. Granting and honoring Indigenous land tenure and protected areas are also key strategies.

More droughts are coming, and the Amazon can’t keep up: Study
- Up to 50% of rainfall in the Amazon comes from the forest itself, as moisture is recycled from the trees to the atmosphere.
- In severe droughts, when the forest loses more water to evaporation than it receives from rain, the trees begin to die. For every three trees that die due to drought in the Amazon rainforest, a fourth tree, even if not directly affected by drought, will also die, according to a new study.
- As trees are lost and the forest dries up, parts of the Amazon will rapidly approach a tipping point, where they will transition into a degraded savanna-like ecosystem with few to no trees.
- The southern and southeastern Amazon are the most vulnerable regions to tipping. Here, deforestation and fires are at their most extreme, driven largely by cattle ranching and soy farming.

Acid test: Are the world’s oceans becoming too ‘acidic’ to support life?
- The world’s oceans absorb about a quarter of humanity’s carbon dioxide emissions, buffering us against higher atmospheric CO2 levels and greater climate change. But that absorption has led to a lowering of seawater pH and the acidification of the oceans.
- The process of ocean acidification is recognized as a leading threat to ocean life due to its impairment of calcifying organisms and other marine species. The full impacts of acidification are unknown, but at some point reduced pH could be disastrous biologically.
- Researchers have designated ocean acidification as one of nine planetary boundaries whose limits, if transgressed, could threaten civilization and life as we know it. But there is debate as to whether there is a global boundary for this process, since acidification impacts some regions and species more or less than others, making it hard to quantify.
- Scientists agree that the primary solution to ocean acidification is the lowering of carbon emissions, though some researchers are investigating other solutions, such as depositing alkaline rock minerals into oceans to lower the pH of seawater.

‘Mind-blowing’ marine heat waves put Mediterranean ecosystems at grave risk
- A recent study reveals the widespread effects of climate change-driven marine heat waves on the ecological communities of the Mediterranean Sea.
- Rises in sea surface temperatures as high as 5° Celsius (9° Fahrenheit) above normal have caused die-offs in 50 different taxonomic groups of animals from around the Mediterranean Basin.
- These far-reaching impacts of the warming sea could devastate the fisheries on which many of the Mediterranean region’s 400 million people rely.
- Researchers advocate bolstering and expanding marine protected areas. Although they can’t hold back the warmer waters that have proven deadly to the sea’s rich biodiversity, these sanctuaries can help ensure that these species don’t have to cope simultaneously with other pressures, such as overfishing or pollution.

Study paints ‘bleak picture’ for nearly all marine life without emissions cuts
- New research published in Nature Climate Change has found that nearly 90% of assessed marine life would be at high or critical risk by 2100 if the world continues upon a high-emissions pathway.
- It found that the risks would be more concentrated in the tropics, and that top predators would be more at risk than species lower down the food chain.
- However, if countries drastically reduce their emissions, the study found that climate risk would decrease for more than 98% of these species.

Video: Biodiversity underpins all, as California is finding out the hard way
- A new episode of “Mongabay Explains” delves into the biodiversity crisis in California, which is known to be one of the most biodiverse states in the U.S., hosting about 6,500 animal species, subspecies and plants.
- California has been bearing the brunt of climate change in recent years as wildfires and drought transform the land.
- The film focuses on three species that are being negatively affected by the climate crisis: California tiger salamanders, acorn woodpeckers, and monarch butterflies.
- The filmmaker says California is the “poster child of what’s happening to our ecosystems around the world.”

Regenerative agriculture in Mexico boosts yields while restoring nature
- Chiapas is Mexico’s second-most biodiverse state and provides 30% of the country’s freshwater, but has lost 55% of its forests for farmland and livestock pasture.
- Now, an unlikely alliance of conservationists, farmers and cattle ranchers is working to incorporate 2.5 million hectares (6.2 million acres) of land into sustainable management schemes, focusing on soil health and aiming to restore and reforest 1.4 million hectares (3.5 million acres).
- The initiative intends to restore soil health and in the process store carbon, free up more land for conservation, and maintain jobs in rural areas.

In a hotter, drier climate, how serious is fire risk to island seabirds?
- A new study suggests that fires on remote islands in southwest Australia pose a rising threat to short-tailed shearwaters and other seabirds as climate change creates hotter and drier conditions.
- In 2021, a research team led by Jennifer Lavers surveyed an island in Western Australia’s Recherche Archipelago a year after a fire event, and found little evidence that short-tailed shearwaters had successfully bred after the fire, ignited by a lightning strike, had swept over most of the island.
- Lavers and her research team suggest that Indigenous-led methods of controlled burning could help reduce the risk of catastrophic fires that would endanger seabirds.
- However, a seabird and island expert not connected with the study disagrees that fire currently poses a major threat, since seabirds have been known to rebound from fires, even after the loss of their fledglings and burrows.

Climate change and overfishing threaten once ‘endless’ Antarctic krill
- Antarctic krill are one of the most abundant species in the world in terms of biomass, but scientists and conservationists are concerned about the future of the species due to overfishing, climate change impacts and other human activities.
- Krill fishing has increased year over year as demand rises for the tiny crustaceans, which are used as feed additives for global aquaculture and processed for krill oil.
- Experts have called on the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the group responsible for protecting krill, to update its rules to better protect krill; others are calling for a moratorium on krill fishing.
- Antarctic krill play a critical role in maintaining the health of our planet by storing carbon and providing food for numerous species.

Overlooked and at risk, seagrass is habitat of choice for many small-scale fishers
- Seagrass meadows, rather than coral reefs, are the fishing grounds of choice for many fishing households in four countries in the Indo-Pacific region, a new study shows.
- Fishers in Cambodia, Tanzania, Indonesia and Sri Lanka identified seagrass meadows as being more easily accessible than coral reefs, often without the need for a boat, and less likely to damage equipment such as nets.
- However, seagrasses around the world are disappearing at rates that rival those of coral reefs and tropical rainforests, losing as much as 7% of their area each year.
- The study makes the case for better-informed management of these marine habitats, to ensure their sustainability for the marine life and people who depend on them.

Sea life may downsize with ocean warming — bringing challenging impacts
- A new model predicts that marine microbes could shrink by up to 30% in the future due to climate change, impacting bigger organisms that eat them including fish, potentially disrupting the food chain from the bottom up. Smaller fish would mean impacted fisheries. Smaller microbes could mean less carbon sequestration.
- Warmer oceans hold less oxygen, and the model predicts that sea life will get smaller in response to more limited oxygen. But scientists have long debated why this downsizing occurs, and some say that other factors not considered in the model could impact oceanic microbes in unexpected ways.
- Accurately predicting warming impacts on marine life could improve ocean resource management.

A clean and healthy environment is a human right, U.N. resolution declares
- On July 28, member states of the U.N. General Assembly voted overwhelmingly to adopt a historic resolution that recognizes that a clean, healthy and sustainable environment is a human right.
- While the resolution is not legally binding, experts say it can give rise to constitutional and legal changes that will positively impact the environment and human well-being.
- The resolution comes at a critical moment in human history as we face an accelerating climate crisis, unprecedented biodiversity loss, and the ongoing threat of pollution.

Chimps digging wells shows learned behavior that may help amid climate change
- A recent study using camera traps and direct observation documented well-digging behavior in a group of chimpanzees in Uganda, initiated by a female that had immigrated into the group.
- Researchers were surprised to observe this behavior in this rainforest-dwelling population as water tends to be easily accessible in this habitat.
- The findings suggest this learned behavior may be helpful for the conservation of this group, as the chimps have picked up an adaptive measure that could help them survive a drought.

Can a country have too many tigers? Nepal is about to find out
- Nepal is expected to announce a much-anticipated doubling of its tiger population to 250 of the big cats from 12 years ago, on International Tiger Day (July 29).
- But critics say the country’s singular focus on increasing the tiger population has overlooked the impacts on communities living near national parks and wildlife reserves, who have suffered an increase in human-tiger encounters.
- They say the country has exceeded the population of tigers that it can comfortably accommodate, even as the government says it has room for up to 400 of the big cats.
- Officials say there are various options to address a tiger surplus, including housing “problem tigers” in zoos, gifting the animals to foreign governments as a form of diplomacy, and, as a last resort, culling the cats.

Study: Climate impacts to disproportionately hurt tropical fishers, farmers
- The majority of 72 coastal communities studied in five countries in the Indo-Pacific region may face significant losses of agricultural and fisheries products — two key food sources — simultaneously under the worst-case climate change projections, a new study shows.
- These potential losses may be coupled with other drivers of change, such as overfishing or soil erosion, which have already caused declining productivity, the study adds.
- But if carbon emissions can be effectively managed to a minimum, the study’s authors say, fewer communities would experience losses in both the agriculture and fisheries sectors, indicating the importance of climate mitigation measures.
- The current global average temperature is 1.1°C (2°F) above pre-industrial times, and climate experts have warned that it could climb to about 3°C (5.4°F) higher by the end of this century if nothing changes.

In world convulsed by climate-driven conflict, are peace parks an answer?
- Conflicts over disputed borders, increasingly exacerbated by climate change, are putting some of the world’s key biodiversity hotspots at risk.
- Even in countries that have avoided border wars, a global campaign of fence building — aimed at keeping out human migrants whose numbers are rising in an era of climate change and sociopolitical unrest — is causing widespread damage to vulnerable natural landscapes and migratory animal species.
- In potential conflict zones like the Himalayas, Eastern Europe, the Caucasus, and the South China Sea, this surging human march across national frontiers has already led to violence, and in some cases to open warfare.
- Border-straddling conservation zones known as peace parks offer a more sustainable way of managing border disputes than militarization and fence building. Peace parks on the U.S.-Canada border and in the Himalayas offer successful examples.

Community-based seed banks in Nepal help conserve native species
- A grassroots movement to revive native varieties of food crops is gaining support in Nepal with the establishment of seed banks across the country.
- Proponents say they hope to nurture seeds that are more resistant to the impacts that Nepal is already seeing from climate change.
- Nepal imports most of its crop seeds, including hybrid varieties; these include 90% of vegetable seeds, nearly 30% of maize seeds, and 15% of rice seeds.

Scientists strive to restore world’s embattled kelp forests
- Kelp forests grow along more than one-quarter of the world’s coastlines, and are among the planet’s most biodiverse ecosystems. But these critical habitats are disappearing due to warming oceans and other human impacts.
- Sudden recent wipeouts of vast kelp forests along the coastlines of Tasmania and California highlighted how little was known about protecting or restoring these vital marine ecosystems.
- Scientists are finding new ways to help restore kelp, but promising small-scale successes need to be ramped up significantly to replace massive kelp losses in some regions.
- Global interest in studying seaweed for food, carbon storage and other uses, may help improve wild kelp restoration methods.

Habitat loss, climate change send hyacinth macaw reeling back into endangered status
- The hyacinth macaw, the world’s largest flying parrot, is closer to return to Brazil’s endangered species list, less than a decade after intensive conservation efforts succeeded in getting it off the list.
- The latest assessment still needs to be made official by the Ministry of the Environment, which is likely to publish the updated endangered species list next year.
- Conservation experts attribute the bird’s decline to the loss of its habitat due to fires in the Pantanal wetlands and ongoing deforestation in the Amazon and Cerrado biomes.
- Climate change also poses a serious threat, subjecting the birds to temperature swings that can kill eggs and hatchlings, and driving heavy rainfall that floods their preferred nesting sites.

Climate change puts Bangladeshi farmers’ reliance on rice varieties to the test
- Bangladeshi farmers overwhelmingly cultivate rice using the BRRI-28 and BRRI-29 varieties developed by the government, despite the availability of more than 100 alternative varieties, some of them better suited to changing climatic patterns.
- Yields are declining for these two popular varieties as arable land becomes more saline, dry, or submerged due to extreme weather phenomena.
- Scientists behind the range of varieties blame the low popularity of the climate-resistant varieties on the failure by government agencies to produce and promote them to farmers.
- But officials refute this, saying they cater to what the farmers demand, which is the two dominant varieties.

With sea ice melting, glacial ice could be a lifeline for polar bears
- Scientists recently discovered a new subpopulation of polar bears living in southeast Greenland that is genetically and behaviorally distinct.
- While most polar bears depend upon sea ice for survival, the polar bears in Southeast Greenland use pieces of glacial ice as habitat and hunting platforms.
- Large numbers of polar bears are expected to decline as climate change accelerates, but small populations may persist in places like this, where the pace of melting is expected to be slower, experts say.

A return to agroecology traditions points the way forward for Malawi’s farmers
- Malawi’s 3.3 million smallholder farming families are the backbone of the country’s economy, but many suffer poverty and food scarcity.
- For some farmers, agroecology has proved a lifeline, allowing them to boost yields and income while reducing the use of synthetic fertilizers.
- From 2012-2017, an initiative called the Malawi Farmer-to-Farmer Agroecology project, or MAFFA, trained 3,000 farmers in Dedza district in agroecology methods, including intercropping, composting, organic pest control and soil management. Years after the close of the program, many participants report ongoing success in using the techniques they learned.
- However, obstacles to wider adoption of agroecology remain, including the long lead time required before agroecology techniques yield results, and a policy framework that has traditionally focused on subsidizing synthetic fertilizers and hybrid seeds.

How will climate change impact cold-water corals? Mostly through food loss, study says
- A new study warns that cold-water corals, also known as deep-water corals, could be most impacted by a decrease in food supply as climate change shifts the dynamics of the planet’s oceans.
- The authors came to this conclusion by examining how cold-water corals survived the last major period of global warming that occurred at the end of the last glacial period and the start of the current interglacial period, which is somewhat analogous to how the Earth is projected to warm by the end of this century.
- However, experts point out that cold-water corals today are subjected to a number of additional stressors, including ocean acidification, destructive fishing practices, and pollution, and that the climate is changing far more rapidly than it did in the past.
- Cold-water corals are considered to be equally important — or perhaps even more important — than tropical corals, which makes understanding their chances of survival of the utmost importance, researchers say.

Podcast: Vandana Shiva on the agroecology solution for the climate, biodiversity crisis and hunger
- On this episode we talk about agroecology, which applies ecological principles to agricultural systems and is considered an important strategy for both mitigating and adapting to global climate change as well as a solution to a number of the other ecological crises we’re facing.
- Dr. Maywa Montenegro, an assistant professor in the department of environmental studies at the University of California, Santa Cruz, joins us to discuss agroecology as a science, a practice, and a movement.
- We also speak with Dr. Vandana Shiva, whose brand new book synthesizes decades of agroecology research and implementation.
- Dr. Shiva shares how agroecology is an effective solution not just to climate change but also to a host of other ecological crises humanity faces, such as water scarcity, land degradation, and biodiversity loss.

Spotted hyenas adapt to climate change in famed Tanzanian park
- Spotted hyenas seem to be adapting to changing rainfall patterns affecting their preferred prey in Tanzania’s Serengeti National Park.
- In the past decade, migratory herds have been arriving later than previously at hyena clan territories in the middle of the Serengeti, forcing lactating females to “commute” further from their dens to find a meal.
- But researchers have observed no change in how much time they spend with their cubs at these dens, suggesting they’re having no trouble locating prey further from home.
- Hyenas are known for their robust and flexible foraging behavior, but researchers caution that in places other than the Serengeti, they may face additional challenges, such as fragmented habitat and intensifying human activity.

Fisher groups are the marine militia in Indonesia’s war on illegal fishing
- Indonesia has a vast maritime area, but not enough personnel to patrol and monitor for illegal and destructive fishing.
- To address this gap, in recent years the government has incentivized fishers and other coastal communities to form monitoring groups that are responsible for patrolling their local waters.
- In the Raja Ampat archipelago in the country’s east, Mongabay meets some of the people who have volunteered for the task of protecting their waters from blast fishing and cyanide fishing, among other violations.

A seagrass restoration project to preserve the past may also protect the future
- Linani Arifin, 40, is a resident of West Yensawai village in Indonesia’s Raja Ampat archipelago, where the coastal ecosystem has been declining due to climate change impacts and development.
- Almira Nadia Kusuma is a young marine scientist who has studied seagrass for years.
- Together, they lead a group of teenagers in West Yensawai in a project to replant seagrass, aiming to protect the village from coastal erosion.
- Globally, seagrasses are disappearing at rates that rival those of coral reefs and tropical rainforests, and Indonesia is considered an important country for seagrass conservation.

As animal seed dispersers go the way of the dodo, forest plants are at risk
- Many plants rely on animals to reproduce, regenerate and spread. But the current sixth mass extinction is wiping out seed-dispersing wildlife that fill this role, altering entire ecosystems.
- Thousands of species help keep flora alive, from birds and bats to elephants, apes and rodents.
- Animals give plants the ability to “move,” with the need for mobility rising alongside warming temperatures and more frequent extreme weather events. Transported elsewhere, plants may be able to “outrun” a warming climate.
- There are growing efforts to restore these critical ecological relationships and processes: protecting and recovering wild lands, identifying and rewilding key animal seed dispersers, reforesting destroyed habitat, and better regulating destructive logging and agricultural practices.

Wildlife don’t recognize borders, nor does climate change. Conservation should keep up
- A set of studies focused on the China-Vietnam border demonstrates that the impacts of climate change will make transboundary conservation even more important for endangered species like the Cao-Vit gibbon and tiger geckos.
- Conservation in transboundary areas is already challenging because of physical barriers, like fences and walls, as well as non-physical ones, such as different legal systems or conservation approaches between countries on either side.
- Changes in climatic factors such as temperature and rainfall are likely to mean that, for many species, suitable habitat may be in a different place than it is now — and in many cases, this could be in a different country

Unseen crisis: Threatened gut microbiome also offers hope for world
- Plants and animals provide a home within themselves to an invisible community of microbes known as the microbiome. But these natural microbial communities are being degraded and altered by human-caused biodiversity loss, pollution, land-use change and climate change.
- On the macro level, habitat loss and diminished environmental microbe diversity, particularly in urban environments, is altering the gut microbiomes of humans and wild animals. Studies have linked microbiome changes to higher risk of chronic and autoimmune diseases.
- Coral bleaching is an extreme example of climate stress-induced microbiome dysfunction: During heat waves, beneficial microbes go rogue and must be expelled, leaving the coral vulnerable to starvation. Microbiome resilience is key to determining corals’ ability to acclimate to changing ocean conditions.
- There are solutions to these problems: Inoculating coral with beneficial microbes can reduce bleaching, while the restoring natural green spaces, especially in socioeconomically deprived urban areas, could encourage “microbiome rewilding” and improve human and natural community health.

Beyond CO2, tropical forests a ‘cool’ solution to climate crisis, study finds
- Forests, increasingly looked to for their role in addressing climate change, can draw carbon from the atmosphere, but they also have more localized impacts on temperature and weather.
- Forests are responsible for about 0.5°C (0.9°F) of cooling globally when their ability to sequester carbon and these biophysical effects are considered, a recent study has found.
- Tropical forests, with their speedy uptake of carbon and the local cooling they provide — by humidifying the air, for example — are considered a “double win” for the climate.

The world’s dams: Doing major harm but a manageable problem?
- Dam construction is one of the oldest, most preferred tools to manage freshwater for various uses. The practice reached a peak internationally in the 1960s and ’70s, but in recent years dam construction has faced increasing global criticism as the hefty environmental price paid for their benefits piles up.
- The flows of most major waterways have been impacted by dams globally. Only 37% of rivers longer than 1,000 km (620 mi) remain free-flowing, and just 23% flow uninterrupted to the sea. Natural flows will be altered for 93% of river volume worldwide by 2030, if all planned and ongoing hydropower construction goes ahead.
- This global fragmentation of rivers has led to severe impacts. Dams have contributed to an 84% average decline in freshwater wildlife population sizes since 1970. More than a quarter of Earth’s land-to-ocean sediment flux is trapped behind dams. Dams also impact Earth’s climate in complex ways via modification of the carbon cycle.
- But dams are needed for energy, agriculture and drinking water, and are an inevitable part of our future. Lessons on how to balance their benefits against the environmental harm they do are already available to us: removing some existing dams, for example, and not building others.

Tropical trees’ growth and CO2 intake hit by more extreme dry seasons
- A new study has found that dry seasons that are warmer and drier than usual can stunt the growth of tropical trees, causing them to take in less carbon dioxide.
- While trees tend to grow more during the wet season, the researchers found that the dry season actually had a stronger impact on tree growth than the wet season.
- As climate change continues to raise temperatures, tropical trees could face increased risk of mortality and the possibility of becoming a net source of carbon, rather than a carbon sink.

In landslide-prone Colombia, forests can serve as an inexpensive shield
- Scientists say that climate change and high deforestation rates will worsen the severity of landslides across Colombia.
- Regular landslides in the country already have a huge human and economic toll; a disaster in Dosquebradas municipality in February killed 14 people after a heavy rainstorm hit the coffee-growing region.
- Yet scientists say that targeted forest restoration and protection offers an inexpensive way to mitigate landslides, with one study in the Colombian Andes showing that it would be 16 times cheaper to invest in forests than to pay the high costs of repairing destroyed roads, power lines and pipelines after landslides.
- Scientists say that using forests to fight landslides would also have major biodiversity benefits in Earth’s second-most biodiverse nation.

Global biodiversity is in crisis, but how bad is it? It’s complicated
- Biodiversity has been defined as one of nine planetary boundaries that help regulate the planet’s operating system. But humanity is crossing those boundaries, threatening life on Earth. The big question: Where precisely is the threshold of environmental change that biodiversity can withstand before it is destabilized and collapses planetwide?
- The planetary boundary for biodiversity loss was initially measured by extinction rates, but this, as well as other measurements, have proved to be insufficient in determining a global threshold for biodiversity loss. At present, a worldwide threshold for biodiversity loss — or biosphere integrity, as it is known now — remains undetermined.
- However, thresholds for biodiversity loss can be clearly defined at local or regional levels when an ecosystem goes through a regime shift, abruptly changing from one stable state to another, resulting in drastic changes to biodiversity in the changed ecosystem.
- While the planetary boundary framework provides one way of understanding biodiversity or biosphere integrity loss, there are many other measures of biodiversity loss — and all point toward the fact that we are continuing to dangerously destabilize life on Earth.

Reaching the Paris Agreement without protecting Indigenous lands is “impossible”, says report
- A new report by the Forest Declaration Assessment says that fulfilling the Paris Agreement won’t be possible without acknowledging and supporting the crucial role of Indigenous peoples and other local communities’ (IPLCs) in protecting lands.
- About 90% of IPLC lands are carbon sinks, say the report authors, Climate Focus and the World Resources Institute (WRI), which analyzed the IPLC lands in Brazil, Colombia, Mexico, and Peru.
- Each hectare of IPLC land sequesters an average of 30 metric tons of carbon every year, about twice as much as lands outside IPLC protection. This equates to about 30% of the four nation’s Paris Agreement targets.
- Countries should facilitate the titling of all IPLC lands, ensure consent to development projects, commit to protecting environmental defenders and make sure IPLCs are included in U.N. targets, says the report.

Traditional knowledge guides protection of planetary health in Finland
- Undisturbed peatlands act as carbon sinks and support biodiversity. Finland has drained 60% — more than 60,000 km2 (23,000 mi2) — of its peatlands, releasing vast amounts of carbon dioxide into the atmosphere, and destroying entire ecosystems.
- But scientists and Finnish traditional and Indigenous knowledge holders are collaborating to rewild and protect peatlands and associated forests and rivers, turning them into carbon sinks again, while bringing back wildlife and supporting fishing, hunting, and even tourism, offering economic benefits to local communities.
- These Finnish collaborations are already serving as both inspiration and guide to those seeking to use rewilding to curb climate change, enhance biodiversity, create sustainable land use systems, and restore forest, freshwater and wetland ecosystems, while supporting traditional communities.
- “Rewilding is very much about giving more freedom to nature to shape our landscapes, and looking at nature as an ally in solving socioeconomic problems,” says Wouter Helmer former rewilding director of Rewilding Europe. “It’s a holistic way of putting nature back on center stage in our modern society.”

Ships sunk in nuclear tests host diverse corals, study says. But do we need them?
- Researchers surveyed 29 warships at Bikini Atoll and Chuuk Lagoon and found that they hosted up to a third of coral genera found on natural reefs in neighboring regions.
- This study has led researchers to ask a controversial question: Can these kinds of shipwrecks act as biodiversity havens for corals?
- While the study does not provide an answer to this question, the authors say this idea should be explored.
- Climate change is one of the biggest threats to coral reefs since rising temperatures can cause widespread bleaching events.

Indigenous-led report warns against ‘simplistic take on conservation’
- To deal with climate change and biodiversity loss effectively and equitably, conservation needs to adopt a human rights-based approach, according to a new report co-authored by Indigenous and community organizations across Asia.
- Unlike spatial conservation targets such as “30 by 30,” a rights-based approach would recognize the ways in which Indigenous people lead local conservation efforts, and prioritize their tenure rights in measuring conservation success.
- Without tenure rights, strict spatial conservation targets could lead to human rights abuses, widespread evictions of Indigenous communities across Asia, and high resettlement costs, the report warned.
- Also without tenure rights, the inflow of money into nature-based solutions such as carbon offsets and REDD+ projects could also result in massive land grabs instead of benefiting local communities.

‘Everything is on fire’: Flames rip through Iberá National Park in Argentina
- Fires in the central Corrientes province of northeast Argentina have burned through nearly 60% of Iberá National Park, home to protected marshlands, grasslands and forests that hosts an array of species.
- Many of the fires originated from nearby cattle ranches, and spread across significant portions of the park due to a prolonged drought.
- Conservationists are working to relocate a number of reintroduced species, including giant river otters and macaws, to places of safety.
- While experts say they expect a substantial loss to biodiversity, they add that the park should mount a rapid recovery thanks to all the rewilding work already done.

Air pollution makes it tough for pollinators to stop and smell the flowers
- Common air pollutants such as those found in car exhaust fumes react with floral scents, leading to reduced pollination by insects, according to new research.
- Researchers used a fumigation facility to control levels of pollution over an open field of mustard plants and observed the effects of these pollutants on pollination by local, free-flying insects.
- The presence of air pollution resulted in up to 90% fewer flower visits and one-third less pollination than in a smog-free field. The largest decrease in pollination came from bees, flies, moths and butterflies.
- The link between poor air quality and human health is well known, but this research points to another way in which air pollution may affect the systems that humans and all other life rely upon.

Tukupu: The women of the Kariña community, guardians of Venezuela’s forests
- Tukupu is Venezuela’s first Indigenous forest business, sustainably managing and reforesting 7,000 hectares (17,300 acres) of the Imataca Forest Reserve in the south-east of the country.
- The business is led mainly by women who have used their ancestral knowledge to restore over 312 hectares (770 acres) of forest, reforest another 113 (280 acres) and dedicate 189 (468 acres) to agroforestry.
- According to the FAO, the equivalent of more than 23 million tonnes of carbon emissions have been avoided, either directly or indirectly, through the project.
- One of the key points of the project has been to figure out how the resources from the forest can be commercialised in a sustainable way that also benefits members of the community.

Safe havens for coral reefs will disappear as oceans warm, study says
- A new study found that coral reef “refugia” — places that have historically protected coral reefs from thermal stress — will decline substantially when global heating reaches 1.5°C (2.7°F) above pre-industrial levels; at 2°C (3.6°F), most coral reef refugia will disappear.
- A loss in refugia will expose corals to thermal stress that they will likely be unable to cope with, most likely leading to large-scale loss of coral reefs that will threaten marine biodiversity and food security.
- The authors suggest that management efforts should be refocused to help coral reefs adapt to a warming ocean and to assist in their migration to more hospitable locations.
- However, efforts to help corals adapt to rising temperatures may be futile as long as carbon emissions continue to rise.

Typhoon exposes biodiversity haven Palawan’s vulnerability — and resilience
- On Dec. 17, 2021, Typhoon Rai hit the Philippines’ Palawan Island, causing severe damage to protected areas including Puerto Princesa Subterranean River National Park (PPSRNP), Cleoptra’s Needle Critical Habitat, Malampaya Sound Protected Landscape and Seascape, and El Nido-Taytay Managed Resource Protected Area.
- The full impact of the storm has not yet been assessed; at PPSRNP, where preliminary surveys have been conducted, more than 2,200 trees were damaged on the park’s fringes and sightings of birds were down by 90%.
- Experts say the storm-damaged forests can recover — if they aren’t disturbed by human incursions, fires, or additional storms.

As climate change melts Antarctic ice, gentoo penguins venture further south
- Researchers have discovered a new colony of gentoo penguins in Antarctica previously unknown to science.
- The colony was found on Andersson Island on the east side of the Antarctic Peninsula, which is the furthest south the species has ever been found in that region.
- Scientists say climate change played a key role in the penguins’ presence on the island, as warming temperatures and record ice melt make new locations habitable for the species.
- Scientists and conservationists are making renewed calls to establish a network for marine protected areas in Antarctica to help safeguard the region as the climate rapidly changes.

Community project helps Kenya aim for climate goals one mangrove tree at a time
- Along Kenya’s southeastern coast, three communities are restoring 460 hectares (1,137 acres) of the Vanga mangrove forest to meet the country’s emission reduction targets, provide a buffer against natural disasters, and support fishing livelihoods.
- The Vanga Blue Forest project has planted more than 1,000 native mangrove trees since it started in 2019, and aims to work with neighboring communities in Tanzania to restore mangrove forests along 140 kilometers (87 miles) of the East African coastline.
- The early stages of the project were a series of trial and error to achieve successful reforestation, as previous efforts a decade earlier had only a 10% survival rate among the 750,000 trees planted.
- The project is involved in the international carbon trade market and has so far sold $44,433 of carbon credits by accumulating 5,023 metric tons of carbon above ground.

Wildlife death toll from 2020 Pantanal fires tops 17 million, study finds
- A new study has found that nearly 17 million animals died in the Pantanal fires in 2020.
- The researchers came to this estimate by conducting distance sampling surveys, walking tracts of the Pantanal shortly after the fires and counting the number of dead vertebrates they encountered.
- However, the researchers say this is likely to be an underestimate since animals may have died underground or may have died later from burn injuries.
- The 2020 fires burned 4.5 million hectares (11 million acres) of the Pantanal, which is about 30% of the entire biome.

Scientists on a quest to map worldwide web of fungi beneath our feet
- Interconnected bodies of fungi form vast underground networks through the Earth’s soils, transporting nutrients and water across ecosystems and sequestering vast amounts of carbon out of the atmosphere.
- Experts agree that protecting fungi and focusing conservation efforts belowground could help to mitigate global challenges like climate change, biodiversity loss, land use change and pollution.
- A new initiative is embarking on the first global effort to document and map the world’s network-forming fungi, using eDNA and machine learning to identify and protect global hotspots of fungal biodiversity.
- Fungi are increasingly viewed as a nature-based solution to manage global carbon budgets, restore degraded ecosystems, remediate contaminated soils and speed the transition toward sustainable agriculture.

Conservation and food production must work in tandem, new study says
- Confining conservation efforts to only 30% of Earth’s land may render a fifth of mammals and a third of birds at high risk of extinction, according to a new study.
- If that 30% were to be strictly protected without accounting for food production activities, it could also result in substantial local or regional food production shortfalls, the researchers said.
- Instead, they propose an integrated land-use planning strategy where conservation and food production goals are considered in tandem, including through mixed approaches like agroforestry.
- Such a model would not only generate less food production shortfalls, but also leave just 2.7% of mammal and 1.2% of bird species at risk of extinction.

Hold the tree planting: Protect ecosystems first for maximum carbon storage, study says
- When it comes to slowing climate change, there’s one natural solution that has recently gripped the world: large-scale tree planting and reforestation.
- But a new study warns that other natural climate solutions should be considered first.
- By comparing different natural climate solutions against four criteria, the study proposes a hierarchy: protect ecosystems first, then improve their management, and lastly restore them.
- Protecting natural ecosystems offered the greatest climate benefits, fairly quickly, at relatively low cost, while at the same time providing other benefits for people and wildlife, such as reducing the impact of extreme weather and yielding clean air and water.

‘Tis the season’ for cold-stunned sea turtles — and their rescue — on Cape Cod
- As cold weather sets in across New England each year, juvenile sea turtles, drawn to the globally warmed summer waters off Cape Cod, Massachusetts, are cold-stunned. If not rescued they die.
- Trained volunteers have already brought more than 100 turtles to the New England Aquarium Sea Turtle Rescue Center this autumn. The number of cold-stunned turtles at Cape Cod has been rising during the last decade, with some seasons logging more than 1,000 stranded turtles — many of them critically endangered Kemp’s ridleys.
- Globally, most cold-stunning events occur on the U.S. Atlantic and Gulf coasts: especially in Massachusetts, North Carolina, Florida and Texas. Last year, more than 10,000 turtles were stranded in Texas alone. Cold-stun events have also been reported in Uruguay, Spain, Canada, Ireland, Denmark, France, and the UAE.
- On Cape Cod, the animals are stabilized at the New England Aquarium’s Sea Turtle Center, then transported to longer term care facilities across the U.S., often flown there by volunteer pilots working with Turtles Fly Too. As extreme weather events and ocean warming increase due to climate change, experts predict cold-stunning events will increase too.

Fighting climate change is a dirty job, but soils can do it | Problem Solved
- The Earth’s soil stores nearly three times as much carbon as all plants, animals and the atmosphere combined, researchers say.
- However, unchecked deforestation, modern industrialized agriculture, the failure to recognize Indigenous land rights, and the continued extraction and burning of fossil fuels are all putting our crucial carbon sinks in the tropics and subarctic permafrost at risk of releasing much of that carbon.
- Experts agree that protecting soil is key to mitigating climate change, and to avoid breaching delicate planetary boundaries that are necessary to sustain human life on the planet.
- Doing so means fundamental shifts in how we grow our food, conserve and restore forests, and swiftly reduce our use of fossil fuels.

New restoration “Playbook” calls for political, economic, and social change
- Leading forest and climate experts have come up with a “playbook” for ecosystem restoration that accounts for climate change and forest loss as not just biophysical and environmental problems, but also deeply political, economic and social issues.
- It defines 10 principles for effective, equitable, and transformative landscapes that its authors say could be game-changing if followed.
- The playbook discusses the importance of ending fossil fuel subsidies and shifting those resources toward ecosystem restoration, renewable energy, and supporting the land rights of local and Indigenous communities that are protecting forests.
- The authors invite IUCN members and leaders at COP26 in Glasgow to consider adopting the Playbook to guide biodiversity conservation, and climate change mitigation in forests and, more broadly, call for structural changes from local to international scale.

In China, agroforestry serves up tea with a spoonful of sustainability
- In Yunnan, China, smallholder farmers applying agroecological principles to tea cultivation have seen results in the form of better-tasting tea, lower management costs, and richer biodiversity.
- With ethical consumerism on the rise, integrating agroecology could be an opportunity for tea farms to contribute toward conservation goals, experts say.
- Tea farmers and scientists have observed a shift toward more sustainable farming practices, but highlight a need for government policy that can further boost these bottom-up changes.
- By sequestering carbon and contributing to local food security, agroforests can help humans adapt to and combat the climate crisis.

The ‘net zero’ bridge to saving the Amazon (commentary)
- Nature cleans up half of humanity’s carbon pollution each year; securing and expanding natural carbon stocks and sinks is a key piece in the effort to manage the climate crisis, right alongside emissions reductions.
- Well-designed natural climate solutions also enhance food security, alleviate poverty, secure freshwater supplies, and protect biodiversity. Companies’ “net-zero” commitments have the potential to provide critical finance for natural climate solutions while at the same time reducing harmful emissions.
- Amazon states have strategies in place to protect forests and support a transition to low-emission development; what they lack is financing. Support for these strategies would help to prevent an Amazon “tipping point” and the loss of one of the world’s most critical carbon sinks.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

What makes a ‘refugee’? It could be a life-or-death question in the climate crisis
- A new analysis by the Environmental Justice Foundation says that international laws covering refugee protection are too narrow for the climate crisis.
- The group is calling for a new global agreement to protect those who are forced to flee the effects of climate change.
- A U.S. National Intelligence Estimate released on Oct. 21 said the world is currently on a trajectory for 2°C (3.6°F) of warming by 2050, underscoring the urgency of planning for climate-related migration.

‘Kew Declaration’ unites experts on reforestation, aims at policymakers ahead of COP26
- More than 2,600 experts and concerned citizens from 113 countries signed the Kew Declaration on Reforestation for Biodiversity, Carbon Capture and Livelihoods.
- The declaration expresses the co-signatories’ concern over large-scale tree plantations of single species and/or non-native trees and proposes that forests be planted to reflect the diversity of natural ecosystems.
- The declaration specifically calls upon “policymakers, financiers and practitioners in countries that have made reforestation pledges” to work with Indigenous and local people and respect their land tenure rights. It also calls for funding and positive financial incentives to be targeted toward reforestation.
- Experts have noted that policies surrounding reforestation could be improved by increasing communication and involvement of people at all levels of projects, especially local communities, Indigenous people and landowners.

On Indigenous Peoples’ Day, celebrating Earth’s unsung environmental stewards
- As people across the U.S. prepare to observe Indigenous Peoples’ Day, Indigenous peoples’ stewardship of natural resources is increasingly being recognized as a critical priority to protect biodiversity.
- As crucial talks to finalize the Post-2020 Global Biodiversity Framework ramp up, some human rights groups fear it will lead to the expansion of protected areas that evict Indigenous peoples and local communities, while impeding conservation efforts.
- To recognize the significant role Indigenous peoples’ play in global conservation efforts, Mongabay rounds up some of this year’s most impactful stories.

On islands that inspired theory of evolution, deforestation cuts uneven path
- The Wallacea region spans Indonesia’s central islands where the biota of Asia and Australasia meet, making it one of the world’s most valuable centers of endemism, home to scores of species found nowhere else on Earth.
- With development pressure expected to escalate over the coming decades, identifying which of the region’s tracts of forest are most at risk is key to preserving its unique biodiversity.
- A new study that models future deforestation risk across the region has found that coastal, small and unprotected biodiversity sites are most at risk, with North Maluku and Central Sulawesi projected to lose significant tracts of forest by 2053.
- The researchers say their results can be used to target programs, such as social forestry, to sites where they will have optimal impact for biodiversity and communities.

With coral cover halved, curbing climate change is only way to slow the loss
- A new study estimates that global coral cover is half what it was in the 1950s, with much of that loss linked to human-driven climate change.
- The shrinking of coral cover has translated into a 60% loss in reef biodiversity.
- Reef fish catches peaked in 2002 and have been declining ever since, taking a toll on coastal populations, especially Indigenous communities who are more dependent than non-Indigenous communities on seafood.
- Some of these threats are being tackled at the level of communities and even countries, but it may not be enough given the global nature of the biggest threat.

The Pantanal is burning again. Will it be another devastating year?
- Fires have reignited in the Pantanal region of South America, the world’s largest tropical wetland, a year after it lost 30% of its biome to the catastrophic fires of 2020.
- With more than 700,000 hectares (1.7 million acres) of the Pantanal already burned, some experts say this year’s fires could be nearly as devastating as last year’s if the situation is not carefully managed and the current fires are not contained.
- Others are not as concerned, noting that fire is part of the natural ecological process in the Pantanal, and that this year’s fires aren’t nearly as damaging or substantial as last year’s.
- One marked difference between 2020 and 2021 is this year’s increased efforts to fight the fires, with government agencies, NGOs and communities working together to protect the Pantanal.

We’ve crossed four of nine planetary boundaries. What does this mean?
- The Earth has nine Planetary Boundaries that determine the threshold beyond which human impact on Earth’s systems will put society at risk. We’ve already crossed four of these boundaries.
- Over the past year, Mongabay’s series on planetary boundaries has focused attention on the implications of crossing them.
- Below are some highlights that cover the consequences of crossing four of those boundaries (and solutions to address them), as well as the looming challenges in preventing humanity from overreaching the boundaries we have yet to cross.

One in three tree species is in the red, new global assessment says
- Of the 60,000 known species of trees, 440 are critically endangered, an assessment spearheaded by Botanic Gardens Conservation International (BGCI) has found.
- There are more threatened tree species in the world today than there are threatened mammal, reptile, bird and amphibian species combined.
- Among tree biodiversity hotspots, which boast a large number of indigenous trees, Brazil, Indonesia and Malaysia fare poorly.
- Lack of in-country expertise is holding back such initiatives, Frank Mbago, a Tanzanian botanist, told Mongabay.

Will ‘ropeless’ fishing gear be seaworthy in time to save endangered whales?
- Perhaps fewer than 360 North Atlantic right whales are alive today, according to researchers’ estimates.
- Scientists blame the declining population on the twin tolls exacted by ship strikes and entanglement in fishing gear.
- “Ropeless” fishing gear that minimizes the number of vertical lines in the water that ensnare right whales has emerged as a potential “home run” solution to the entanglement crisis.
- But fishers, industry groups and even ardent proponents of ropeless systems say that it’s not yet a viable replacement for traditional fishing gear in every situation.

Building the Campaign for Nature: Q&A with Brian O’Donnell
- In 2018, philanthropist Hansjörg Wyss put $1 billion toward initiatives to help a range of stakeholders conserve 30% of the planet in its natural state by 2030. One of the products of that commitment is the Campaign for Nature, an advocacy, communications, and alliance-building effort to turn that 30×30 target into a reality.
- The campaign’s strategy has three major components: building political support for 30×30, ensuring Indigenous and local community rights are advanced in the Post-2020 Global Biodiversity Framework, and boosting funding for nature conservation, especially for developing countries where biodiversity is concentrated.
- The Director of Campaign for Nature is Brian O’Donnell, who told Mongabay that more than 70 countries have endorsed the “30×30” goal over the past three years, but that many leaders still do not recognize or understand the importance of protecting biodiversity.
- “Global leaders have not given biodiversity the attention it warrants. Most global leaders do not fully understand or value the importance of biodiversity, and are not aware of the scale of the current crisis facing biodiversity,” he said. “Protecting at least 30% of the world’s lands, freshwater and oceans will help prevent extinctions, provide clean water to communities, reduce the impacts of storms, and improve the health of the world’s oceans.”

Convergence, community and justice: Key emerging conservation trends of the pandemic era (commentary)
- As a product of the profound impacts of climate-induced disasters, the pandemic, and rising awareness of social injustice, the conservation sector is in the midst of a period of rapid change.
- Fred Nelson, the CEO of Maliasili, which works to scale the impact of local conservation and natural resource organizations in Africa, identifies four key trends that are “significantly reshaping the conservation field” and what these mean for the sector.
- “Conservation organizations should anticipate greater support for locally-led or community-based organizations and initiatives, continued and increasing interest in the intersection of the environment and social justice, and more funding and policy support for the central role of healthy ecosystems in addressing climate change,” Nelson writes. “Ultimately these trends are all creating important opportunities for strengthening the conservation field in crucial ways—with more resources, deeper partnerships, greater diversity, and stronger local and grassroots leadership—during this critical period.”
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Climate change threatens to squeeze out Indonesia’s medicinal plants
- More than half of medicinal plant species in Indonesia won’t be able to grow in most of their current range by 2050 due to climate change, a new study says.
- Researchers say medicinal plant species on the islands of New Guinea, Java and Sulawesi will see the largest reduction in distribution area, in part due to sea level rise in these regions.
- The economic value of medicinal plants in Indonesia, coupled with other threats and a lack of resources for their conservation, makes it urgent that active conservation programs be put in place, the researchers say.
- Medicinal plants are valuable species not only for personal health but also for their economic value as they are traded by local and Indigenous communities.

‘Shared earth’ conservation promises to prioritize nature and people
- A new article in Science calls for conservation in Africa to take a “shared earth” approach that prioritizes both nature and people.
- According to the authors, this approach would empower local communities, Indigenous people and governments to make decisions that would meet both equity and biodiversity goals.
- The authors suggest retaining or restoring 20% of living and working areas to help address global conservation targets while giving local people the benefits of nature and building resilience against climate change.

Platform presents unpublished data on Brazilian biodiversity
- Partnership between scientists and journalists translates scientific data into visual information to warn of the importance of preserving Brazil’s biomes.
- Brazil alone accounts for 17% of the entire terrestrial territory of the tropics with a biodiversity that is more abundant than entire continents: over 20% of the freshwater fish on the planet and 17% of all birds are found in Brazil.
- One problem is the lack of investment in research to survey biodiversity, which usually comes at a slower pace than changes in ecosystems – animals and plants are at risk of disappearing before scientists are able to get to know them.

Podcast: What can seashells tell us about the health of the oceans?
- On today’s episode of the Mongabay Newscast we discuss what seashells can tell us about the state of the world’s oceans, and we hear about the challenges facing the Philippines’ marine protected area system.
- Environmental journalist Cynthia Barnett joins us to discuss her newly released book, The Sound of the Sea: Seashells and the Fate of the Oceans. She tells us about the many ways humans have prized seashells for years, using them as money, jewelry, and art, and how seashells can help us examine the challenges marine environments are facing today.
- We’re also joined by Mongabay staff writer Leilani Chavez, who tells us about the incredible marine biodiversity found in Philippines waters and why there’s a movement amongst scientists and conservationists to expand marine conservation efforts beyond the Philippines’ extensive coral reef systems.

Soil and its promise as a climate solution: A primer
- We know that soil feeds plants, but do we know how it got there in the first place? Soil forms via the interaction of five factors: parent material, climate, living beings, a land’s topography, and a “cooking” time that occurs on a geologic scale. Variations in these 5 factors make the world’s soils unique and extremely diverse.
- Soil acts as a carbon sink in the global carbon cycle because it locks away decomposed organic matter. But deforestation, various agricultural practices, and a changing climate are releasing it back into the atmosphere and oceans as carbon dioxide, resulting in an imbalance in global carbon budgets
- Tropical soils and permafrost hold the most soil carbon out of other biomes, making them conservation and research priorities in soil-centered climate solutions.
- Reforestation of previously forested lands is a viable solution to return carbon belowground, but it is not a fix-all. Changing industrial agricultural practices and giving high-carbon storage areas conservation status are key steps toward harnessing the soil’s carbon storage power.

Meet the kitten-sized, clown-faced monkey that’s leaping toward extinction
- The buffy-headed marmoset is down to no more than 2,500 individuals scattered across dwindling patches of Brazil’s Atlantic Forest.
- It faces a range of threats, from yellow fever to climate change, but the biggest one is hybridization with other marmoset species released into its habitat from the pet trade.
- Conservationists working to save the species warn that populations are declining rapidly, with little funding for studies or captive-breeding programs, and a lack of political will under the current government to act urgently.
- One possible conservation solution is to establish “safe haven” forests for unmixed buffy-headed marmosets that will exclude hybrid animals, but this will difficult and costly, experts say.

Global restoration now has an online meeting point
- Restor is a map-based, open-source platform created so that people can better plan, manage and monitor restoration projects. The locations of more than 50,000 restoration and conservation initiatives are now registered on the platform.
- On the platform, Restor users can view high-resolution satellite imagery of places around the globe to learn about their potential for restoration or conservation. It also allows users to see what tree species are native to a particular location.
- Currently, Restor is collecting data from restoration projects around the world. Anyone with a project can apply for access to the site where they are able to enter data about their project and ecosystem.
- Restor CEO Clara Rowe says they hope to “enable and accelerate ecological restoration … around the globe by making it easy for anyone, anywhere to engage.”

Hotter and drier: Deforestation and wildfires take a toll on the Amazon
- Drought and high temperatures amplify the destructive effects of deforestation and wildfires.
- Across the Amazon Basin, tree species adapted to drier conditions are becoming more prevalent, and in the Central Amazon, savannas have replaced floodplain forests in just a few decades.
- While deforestation remains a main concern, the impacts of forest degradation are becoming increasingly important.

Rush to turn ‘black diamonds’ into cash eats up Uganda’s forests, fruits
- As recently as 2018, only a little over 42% of Ugandans had access to electricity — many were too poor to afford it. As of 2016-17, 90% of all households burned wood fuel for cooking, with just 15.5% using charcoal in rural areas, but 66.4% of urban households using it.
- Those using charcoal account for roughly 23% of the country’s total population, which means that some 10.7 million citizens in a nation of 46.8 million rely on charcoal to cook their meals, based on recent U.N. data.
- Charcoal producers are working hard to meet this exploding demand, degrading and depleting the nation’s forest reserves, and now buying up fruit trees on private lands to make into briquettes. Many charcoal producers lack the licenses required by the government, so are cutting trees and making charcoal illegally.
- The surging charcoal industry is destroying Uganda’s forests and biodiversity, while briquette burning is also causing respiratory and other health problems, and its carbon emissions are adding significantly to global climate change.

Scientists call for solving climate and biodiversity crises together
- A new report from United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) highlights the importance of confronting climate change and biodiversity loss together.
- Global climate change and the unprecedented loss of species currently underway result from a similar suite of human-driven causes, the report’s authors write.
- As a result, solutions that take both issues into account have the best chance of success, they conclude.

U.N. declares decade of ecosystem restoration to ‘make peace with nature’
- The U.N. has declared the coming decade a time for ecosystem restoration, highlighting in a new report the importance of preventing, halting and reversing ecosystem degradation worldwide.
- It calls on the world to restore at least 1 billion hectares (2.5 billion acres) of degraded land in the next decade — an area larger than China — warning that degradation already affects the well-being of 3.2 billion people.
- The report also makes an economic case for restoration, noting that for every dollar that goes into restoration, up to $30 in economic benefits are created.
- A key message of the report is that nature is not something that is “nice to have” — it is essential to our survival, and we are a part of it.

New Attenborough film sounds alarm on planetary boundaries, but offers hope
- A newly released Netflix documentary, “Breaking Boundaries: The Science of Our Planet,” features David Attenborough and Johan Rockström, one of the scientists who introduced the concept of planetary boundaries.
- Planetary boundaries are Earth system processes essential for the planet’s functioning but have an environmental limit to which they can tolerate changes.
- According to experts, if these limits are transgressed, the Earth can be pushed into a new, dangerous state.
- While the film suggests that the planet requires urgent repair, it also offers a clear path forward — and a message of hope.

Podcast: Can Biden’s 30×30 plan put U.S. on a positive conservation track?
- On today’s episode of the Mongabay Newscast, we discuss the 30×30 conservation plan recently released by the administration of US President Joe Biden and its potential to transform the way the US conserves its natural resources.
- Joe Walston, executive vice president of global conservation for the Wildlife Conservation Society, tells us that the Biden 30×30 plan has been welcomed by environmentalists, even though many important details of the plan still need to be hammered out, and that it sends a signal to the rest of the world that the US is once again looking to lead the world in conservation.
- Sarah Derouin, a Mongabay contributor and a producer of the weekly radio show and podcast “Big Picture Science,” tells us about two agroforestry programs that are already changing the way food is produced in the US and how agroforestry might help meet the 30×30 targets.

The key to averting environmental catastrophe is right beneath our feet
- Billions of years ago, the first soils served as a cradle for terrestrial life. Today, the land beneath our feet underpins a multitrillion-dollar, global agricultural industry and provides food for nearly 8 billion humans, along with countless wild and domestic species. But soils are in global crisis.
- We are now living in the “danger zone” for four of the nine planetary boundaries: climate change, biodiversity, land-use change, and biogeochemical flows. All four are intimately linked to soil health. Soils hold 80% of all the carbon stored on land.
- Deteriorating soil health is already gravely impacting lives and livelihoods. Land degradation due to human activities costs around 10% of global gross product. When combined with climate change effects, soil degradation could reduce crop yields by 10% globally by 2050.
- There is an inevitable delay between recognizing global problems and enacting solutions, and seeing the resulting boost to ecosystem services. That’s why we must act now if we are to leverage soil ecosystems in the fight against disastrous global environmental change.

Protected areas now cover nearly 17% of Earth’s surface: U.N. report
- A new report from the United Nations Environment Programme and the International Union for Conservation of Nature reveals that countries are closing in on the target set in 2010 of protecting or conserving 17% of the Earth’s surface.
- Since 2010, the area of the marine environment that’s under protection has more than tripled, although global coverage is less than 8%, falling short of the 10% goal set in Aichi Target 11.
- While there has been some success, international leaders agree there should be more focus on quality as well as quantity in designating protected and conservation areas.
- As the U.N. Biodiversity Conference scheduled for October 2021 in Kunming, China, approaches, the report calls for a stronger emphasis on the contributions of Indigenous and local communities, while also ensuring that the world’s poorest don’t shoulder an outsize burden from these efforts.

How to pick a tree-planting project? Mongabay launches transparency tool to help supporters decide
- Mongabay has put together a database to show whether tree-planting and reforestation projects publicly disclose the criteria that experts say are keys to success.
- Our directory is built on a three-month research effort to record publicly available information on more than 350 tree-planting projects in 80 countries.
- Rather than make an assessment (and perceived endorsement) of the quality of the projects, Mongabay’s review is based on how much information is publicly disclosed by an organization.
- Here, we present some key questions to ask and criteria to consider when evaluating the legitimacy and effectiveness of a tree-planting project.

New paper urges shift to ‘nature positivity’ to restore Earth
- A new paper, published by leading conservationists and the heads of various global institutions, argues for adopting a “nature-positive” goal.
- This would require restoring the Earth from 2020, placing the world on a nature positive path by 2030 to mount a full recovery by 2050.
- According to the authors, nature positivity would provide an overarching goal for nature that would coincide with the Convention on Biological Diversity’s (CBD) mission and streamline agreements for climate, biodiversity, and sustainable development into one common vision.
- The paper was released a few days before the start of the meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA), where parties will provide advice on the CBD’s post-2020 global biodiversity framework.

Arctic biodiversity at risk as world overshoots climate planetary boundary
- The Arctic Ocean biome is changing rapidly, warming at twice the rate of the rest of the world. In turn, multiyear sea ice is thinning and shrinking, upsetting the system’s natural equilibrium.
- Thinner sea ice has led to massive under-ice phytoplankton blooms, drawing southern species poleward; fish species from lower latitudes are moving into the peripheral seas of the Arctic Ocean, displacing and outcompeting native Arctic species.
- Predators at the top of the food chain, such as polar bears, are suffering the consequences of disappearing ice, forced onto land for longer periods of time where they cannot productively hunt.
- The Central Arctic Ocean Fisheries Agreement has been signed by 10 parties to prevent unregulated commercial fishing in the basin until the region and climate change impacts are better understood by scientists. International cooperation will be critical to protect what biodiversity remains.

‘Profound ignorance’: Microbes, a missing piece in the biodiversity puzzle
- Researchers are certain that human activity has resulted in a decline in plant and animal species. But a huge unknown remains: what impacts have human actions —ranging from climate change, to ocean acidification, deforestation and land use change, nitrogen pollution, and more — had on the Earth’s microbes?
- A new paper poses this significant question, and offers a troubling answer: Science suffers from “profound ignorance” about the ways in which microbial biodiversity is being influenced by rapid environmental changes now happening on our planet.
- Researchers are supremely challenged by the microbial biodiversity question, finding it difficult to even define what a microbe species is, and uncertain how to effectively identify, analyze and track the behaviors of microbes on Earth —microorganisms estimated to be more numerous than stars in the known universe.
- We do know microbes play crucial roles — helping grow our food, aiding in the sequestering and release of soil carbon, curing and causing disease, and more. One thing researchers do agree on: knowing how human activities are influencing the microbial world could be very important to the future of humanity and our planet.

Humanity’s dysfunctional relationship with Earth can still be fixed, report says
- A new report released in the leadup to the “Our Planet, Our Future” Nobel Prize Summit, provides an overview of the numerous challenges facing our planet due to human pressures, including the transgression of several planetary boundaries that help regulate and stabilize the Earth.
- However, it also considers ways in which global sustainability can be achieved through transformative change.
- The authors say that emerging technologies, social innovations, shifts in cultural repertoires, and different approaches to biosphere stewardship can all play a part in paving the way for a more sustainable future.
- The Nobel Prize Summit, which will be the first of its kind, will take place between April 26 and 28, and will discuss what can be learned from the global pandemic we’re currently experiencing, and the changes that can be made in this decade to help achieve global sustainability.

Jamaican Climate Change Youth Council seizes opportunity to continue advocacy amidst pandemic
- The Jamaica Climate Change Youth Council (JCCYC) is active and effective in its climate change advocacy mission for several reasons, says executive director Eleanor Terrelonge.
- It’s targeting the more engaged youth demographic in the region through the digital media that they’re most familiar with.
- It also has a full slate of events for the week leading up to Earth Day, through which it hopes to raise awareness, encourage discussion, and promote engagement.
- Terrelonge says the COVID-19 pandemic has shone a light on a lot of issues linked to climate change, and serves as a preview of the long-term impact of climate change.

Island species and endemics will bear brunt if warming exceeds 3°C: Study
- Endemic species on islands, especially plant species, are at the greatest risk of disappearing because of climate change, a study has found.
- In general, species found exclusively in one region face a greater threat from a changing climate than native and introduced species, with the latter likely to face almost no negative effects at all.
- Places like the Caribbean, the Indian Ocean islands, including Madagascar and Sri Lanka, the Philippines, and biomes like India’s Western Ghats could be bereft of all their endemic plant life in three decades, according to the analysis.
- Introduced species could outcompete and replace endemic species in the world’s biodiversity hotspots if warming continues unchecked.

Podcast: Though humanity exceeds key ‘planetary boundaries’ there are many solutions
- On this episode of the Mongabay Newscast, we speak with two recent contributors to our “Covering the Commons” special reporting project who wrote pieces that deal with the concept of Planetary Boundaries and how we can build a more sustainable future.
- Claire Asher tells us about her recent article detailing the nine Planetary Boundaries, the four environmental limits we’ve already exceeded, and the chances 2021 offers us to make transformative change.
- Andrew Willner discusses his recent article on how a “New Age of Sail” might soon transform the international shipping industry, the sixth-largest source of carbon emissions in the world.

The nine boundaries humanity must respect to keep the planet habitable
- All life on Earth, and human civilization, are sustained by vital biogeochemical systems, which are in delicate balance. However, our species — due largely to rapid population growth and explosive consumption — is destabilizing these Earth processes, endangering the stability of the “safe operating space for humanity.”
- Scientists note nine planetary boundaries beyond which we can’t push Earth Systems without putting our societies at risk: climate change, biodiversity loss, ocean acidification, ozone depletion, atmospheric aerosol pollution, freshwater use, biogeochemical flows of nitrogen and phosphorus, land-system change, and release of novel chemicals.
- Humanity is already existing outside the safe operating space for at least four of the nine boundaries: climate change, biodiversity, land-system change, and biogeochemical flows (nitrogen and phosphorus imbalance). The best way to prevent overshoot, researchers say, is to revamp our energy and food systems.
- In 2021, three meetings offer chances to avoid planetary boundary overshoot: the Convention on Biological Diversity meeting in Kunming, China; the U.N. Climate Summit (COP26) in Glasgow, U.K.; and the U.N. Food Systems Summit in Rome. Agreements with measurable, implementable, verifiable, timely and binding targets are vital, say advocates.

Podcast: Are biomass and hydropower ‘false’ climate solutions?
- On this episode of the Mongabay Newscast, we look at two energy-related technologies that are being promoted as climate solutions, biomass and hydropower, which might have unintended consequences that hamper their ability to supply clean energy and thus might not be sustainable solutions at all.
- Our first guest is Justin Catanoso, a professor at Wake Forest University and long-time Mongabay correspondent. Catanoso tells us about the loopholes in renewable energy policies that have allowed the biomass industry to flourish under the guise of “carbon neutrality,” even though the burning of biomass for energy releases more carbon emissions than burning coal.
- We also speak with Ana Colovic Lesoska, a biologist by training who founded the Eko-Svest Center For Environmental Research in North Macedonia. Colovic Lesoska was instrumental in shutting down two large hydropower projects in her country’s Mavrovo National Park, but there are still more than 3,000 new hydropower projects proposed in the Balkans. She tells us why hydropower is being adopted by Balkan countries and whether or not hydropower can be a climate solution at any scale.

Podcast: Agroforestry, an ancient climate solution that boosts food production and biodiversity
- On today’s episode of the Mongabay Newscast, we speak with three different guests about why agroforestry is increasingly being implemented worldwide to address industrial agriculture’s contributions to the global environmental crises we’re facing as well as to create new livelihood opportunities and build food security for local communities.
- Agroforestry is the practice of incorporating woody perennials like trees and shrubs into a system with agricultural crops or livestock. It’s been practiced by indigenous peoples for thousands of years, and they are still perhaps the chief practitioners of it today.
- We speak with Mongabay’s own Erik Hoffner, who edits Mongabay’s ongoing coverage of agroforestry, as well as Sarah Lovell, who talks about agroforestry in the US, and Roger Leakey, who discusses agroforestry in the tropics.

Death by 1,000 cuts: Are major insect losses imperiling life on Earth?
- New studies, featured in a recent edition of the Proceedings of the National Academy of Science, assess insect declines around the planet.
- On average, the decline in insect abundance is thought to be around 1-2% per year or 10-20% per decade. These losses are being seen on nearly every continent, even within well-protected areas.
- Precipitous insect declines are being escalated by humanity as soaring population and advanced technology push us ever closer to overshooting several critical planetary boundaries including biodiversity, climate change, nitrification, and pollution. Planetary boundary overshoot could threaten the viability of life on Earth.
- Action on a large scale (international, national, and public/private policymaking), and on a small scale (replacing lawns with insect-friendly habitat, for example) are desperately needed to curb and reverse insect decline.

Humanity’s ‘ecological Ponzi scheme’ sets up bleak future, scientists warn
- In a recently published perspective piece, 17 leading scientists say the world is facing a “ghastly future” due to ongoing environmental degradation, including biodiversity loss, climate change, and human overpopulation and overconsumption.
- The authors say their message is meant to give a “cold shower” to leaders who can help make positive changes for the planet.
- While other scientists agree with some of the report’s messages, they point out several issues with the argument’s framework, including its possible misidentification of migration and population growth in places like sub-Saharan Africa as driving environmental problems.

Biden’s election is good news for the climate. But what comes next?
- U.S. president-elect Joe Biden’s climate agenda has been described as the most ambitious of any U.S. presidential candidate in history.
- If Republicans retain control of the U.S. Senate, it will be difficult to pass sweeping climate legislation, but analysts say there are opportunities for bipartisan cooperation.
- Biden has pledged to sign a series of climate-related executive orders, including a ban on fossil fuel extraction on public land.
- His administration will have wide leeway to align U.S. foreign policy with his climate goals, most prominently by immediately rejoining the Paris Agreement.

IPBES report details path to exit current ‘pandemic era’
- A new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) calls for a “transformative change” in addressing the causes of virus outbreaks to prevent future pandemics and their devastating consequences.
- Human-driven climate change, the wildlife trade, and conversion of natural ecosystems all increase the potential for the spillover of viruses that infect animals to people.
- The current COVID-19 pandemic is likely to cost the global economy trillions of dollars, yet preventive measures that include identification of the hundreds of thousands of unknown viruses that are thought to exist would cost only a fraction of that total.

On a Philippine mountain, researchers describe a ‘fire flower’ orchid species
- A new wild orchid species, Dendrochilum ignisiflorum, has been described in the Philippine province of Benguet in the northern Cordilleras mountain range.
- This fiery orange orchid belongs to a genus found in high-elevation forests in Southeast Asia, particularly in the Philippines, Borneo and Sumatra.
- The scientists who described it say the species is threatened by climate change, which could make its niche range uninhabitable.
- The mountain where it’s found is also an increasingly popular tourist spot, while the forests in the area around it are being cleared for agriculture.

The Amazon savanna? Rainforest teeters on the brink as climate heats up
- A new study has found that 40% of the Amazon is at risk of turning into savanna due to decreases in rainfall.
- The paper’s authors used satellite data, climate simulations and hydrological models to better understand the dynamics of rainfall across the tropics and their impacts on the stability of tropical forest ecosystems.
- The team’s simulations suggest that sustained high greenhouse gas emissions through the end of the century could shrink the minimum size of the Amazon by 66%.

World’s protected areas lack connections, recent study finds
- A recent study, published in the journal Nature Communications, has found that 9.7% of the world’s protected areas are connected by land that’s considered intact.
- The study used the human footprint database, which maps out human impacts, such as roads and farmland, across the planet.
- The research showed that, while some countries have protected 17% of their land — a goal set forth in the U.N. Convention on Biological Diversity’s Aichi targets — others, including repositories of biodiversity such as Vietnam and Madagascar, are lagging with little to no connectivity in their networks of reserves.
- The authors suggest that the research could help guide decisions on which areas of land to protect and how to connect them in a way that gives species the best shot at survival.

Video: In this Philippine community, women guard a marine protected area
- Women in the central Philippines have banded together to protect their marine sanctuaries from poachers and illegal fishers.
- Armed with only paddles and kayaks, these women willingly risk their lives to manage their marine protected area.
- Philippine waters are teeming with rich coral reefs and fish diversity and abundance, but protecting the seascape is challenging due to illegal fishing and climate change.

We are failing to save the planet’s species, finds UN report
- In an effort to slow the ongoing sixth mass extinction and safeguard the world’s plants and animals, 20 Aichi Biodiversity Targets were established in 2010. According to a recently released U.N. report, not one goal was met completely.
- Little progress has been made towards eliminating, phasing out or reforming subsidies and other incentives potentially harmful to biodiversity. An estimated $500 billion in government subsidies potentially cause environmental harm, the report states.
- The establishment of the target area of marine and freshwater protected areas has been nearly met. Some extinctions, including up to seven mammal and eighteen bird species, have been prevented by conservation efforts in the past decade.
- Looking to the future, the report outlines eight transitions needed to shift humanity away from “business as usual” toward “a society living in harmony with nature.” However, “action is needed now.”

Climate change could put tropical plant germination at risk: Study
- Under a worst-case climate change scenario, more than 20% of plant species in the tropics may experience temperatures too high for their seeds to germinate by 2070, according to an analysis of seed germination data compiled by the UK’s Royal Botanic Gardens Kew.
- Under that same worst-case scenario, over half of tropical species may see reduced rates of germination by 2070 as well, the study reports, while many temperate species at high latitudes will move closer to their optimum temperature and may experience increased germination success as a result.
- The analysis shows that 26% of tropical species and 10% of temperate species are already experiencing temperatures above their optimum. Some plants are found living at sites where temperatures are already above their maximum, suggesting that their lineage in that location may be effectively extinct.
- Plants that find themselves outside of optimum or tolerable temperature ranges may be able to migrate to higher latitudes or altitudes, and existing diversity can offer a reservoir of genetic variation for species to adapt, but physiological limits and long generation times may mean even diverse species struggle.

Fires in Argentina’s Paraná Delta are burning ‘out of control’
- Hundreds of fires are currently burning through the Paraná Delta region, an important wetland ecosystem that hosts a range of wildlife in Argentina, raising concerns among conservationists.
- The Paraná River is also experiencing extremely low water levels due to a regional drought, although experts say an exact climatic reason for the drought has yet to be determined.
- Experts say most of the fires have been deliberately lit by people, but they are now raging “out of control” due to drought, lack of rainfall and low river levels.

Photos show scale of massive fires tearing through Siberian forests
- A series of newly released images from Greenpeace International show megafires burning through the Krasnoyarsk region of Siberia, Russia.
- It’s estimated that fires have burnt more than 20.9 million hectares of land in Russia, and 10.9 million hectares of forest, since the start of 2020.
- The fires are being helped by unusually warm temperatures, including a reading of more than 38° Celsius (100° Fahrenheit) in the town of Verkhoyansk — the hottest on record inside the Arctic Circle.
- There are concerns that the smoke from the Siberian fires will cause respiratory problems for people living in urban areas, especially in the midst of the COVID-19 pandemic.

New study quantifies impact of hunting on migratory shorebird populations
- Hunting might be a major threat for thousands of migratory shorebirds in the East Asian-Australasian Flyway (EAAF), one of the major corridors for migratory birds in the world.
- A new study shows that hunting has contributed to the demise of at least a third of migratory shorebirds in the flyway since the 1970s.
- The flyway, which spans 22 countries from the Arctic to Australia, is the most threatened flyway among the nine migratory bird corridors in the world, with habitat loss and climate change the main drivers of the plummeting population.
- Around 50 million waterbirds pass through the flyway on an annual basis, but recent data shows a 61% decline in migrating waterbird species.

This Philippine butterfly had a mistaken identity for years, until its ‘rediscovery’
- A pair of scientists have discovered a new subspecies of butterfly whose only known habitat is at the peak of a potentially active volcano in the central Philippines.
- Specimens of the new subspecies, Appias phoebe nuydai, were first collected in 2012 by researcher Jade Badon, who initially misidentified them as belonging to a different phoebe subspecies.
- The researcher realized in 2019 that the species was different after comparing its forewings to existing cataloged species.
- Climate change is the biggest possible threat to high-elevation butterflies, with researchers calling for more studies into how the butterflies are adapting.

Communities on Brazil’s ‘River of Unity’ tested by dams, climate change
- The Pixaim Quilombo is one of many traditional communities made up mostly of Afro-Brazilian descendants of runaway slaves. It sits at the mouth of the São Francisco River, one of Brazil’s most important waterways.
- Once a thriving community, it has been struggling for decades due to the impacts of upriver dams which reduce the river’s flow and alter aquatic migrations. As a result, one of the community’s two chief livelihoods has been sharply curtailed — the river’s fishery is in steep decline.
- Now, climate change threatens to make those struggles even greater, further changing fish populations, reducing river flow even more, and dangerously elevating the salinity of the stream as seawater intrudes. Rice, which once provided Paixim’s second major livelihood, can no longer be grown in the delta’s saltier marshes.
- Pixaim is seeing a major outmigration as subsistence livelihoods becomes more difficult. Residents there count among 18 million people residing in the São Francisco River watershed, impacted by a steadily dwindling water resource.

They survived centuries of elephant onslaught. Now climate change is killing these iconic baobabs
- A years-long drought across Southern Africa, exacerbated by climate change and over-use of water by industry, has driven elephants into South Africa’s Mapungubwe National Park.
- Here, they tear into the park’s centuries-old babobab trees to get at the moist interior.
- While the babobabs have evolved to tolerate occasional elephant damage and benefit from elephants eating their fruit and dispersing the seeds, the damage done during times of drought is extensive and often deadly for the trees.
- The elephants, for their part, no longer have room to maneuver: they’re trapped between climate change, habitat destruction and poaching.

Disaster interrupted: How you can help save the insects
- In a new paper, a group of 30 scientists offers suggestions for industry, land managers, governments and individuals to protect insects in the face of a global decline.
- Noting that invertebrates lack the “charisma” of larger species like pandas and elephants, the scientists call for spreading “the message that appreciation and conservation of insects is now essential for our future survival.”
- They suggest a list of actions that individuals can take to help, including planting native plants, going organic and avoiding pesticides, and reducing carbon footprint.
- “As insects are braided into ecosystems, their plight is essentially integrated with more expansive movements such as global biodiversity conservation and climate change mitigation and in an alliance with them,” the scientists say.

As Indonesia fights COVID-19, warmer temperatures drive up dengue cases
- Dengue fever has been on the rise in Indonesia this year, even as the country focuses on dealing with the COVID-19 pandemic.
- Experts have attributed the increase to warmer average temperatures and unsanitary conditions that allow the mosquitoes carrying the virus to thrive.
- Authorities have ordered fumigation drives in response to the outbreak, but health experts warn the mosquitoes are developing a resistance to the insecticides used.

Rapid deforestation of Brazilian Amazon could bring next pandemic: Experts
- Nearly 25,000 COVID-19 cases have been confirmed in Brazil, with 1,378 deaths as of April 15, though some experts say this is an underestimate. Those figures continue growing, even as President Jair Bolsonaro downplays the crisis, calling it “no worse than a mild flu,” and places the economy above public health.
- Scientists warn that the next emergent pandemic could originate in the Brazilian Amazon if Bolsonaro’s policies continue to drive Amazon deforestation rates ever higher. Researchers have long known that new diseases typically arise at the nexus between forest and agribusiness, mining, and other human development.
- One way deforestation leads to new disease emergence is through fire, like the Amazon blazes seen in 2019. In the aftermath of wildfires, altered habitat often offers less food, changing animal behavior, bringing foraging wildlife into contact with neighboring human communities, creating vectors for zoonotic bacteria, viruses and parasites.
- Now, Bolsonaro is pushing to open indigenous lands and conservation units to mining and agribusiness — policies which greatly benefit land grabbers. Escalating deforestation, worsened by climate change, growing drought and fire, heighten the risk of the emergence of new diseases, along with epidemics of existing ones, such as malaria.

For nesting hawksbill turtles, this Philippine community is a sanctuary
- For centuries, hawksbill sea turtles have returned to a shoreline in the eastern Philippines to lay their eggs, even as the human community has expanded along the same stretch of beach.
- Hawksbill sea turtles’ low survival rates in the wild are caused by natural predators and, recently, exacerbated by rising sea levels. Another key threat is poaching for their meat and shells.
- Despite the lack of financial support, locals continue to look after the eggs, coming up with their own ways to protect them until the hatchlings are ready to be released back into the sea.

Extreme El Niño drought, fires contribute to Amazon insect collapse: Study
- A recent study found that dung beetle species experienced significant diversity and population declines in human-modified tropical Brazilian ecosystems in the aftermath of droughts and fires exacerbated after the 2015-2016 El Niño climate event.
- Forests that burned during the El Niño lost, on average, 64% of their dung beetle species while those affected only by drought showed an average decline of 20%. Dung beetles provide vital ecoservices, processing waste and dispersing seeds and soil nutrients.
- For roughly the past three years, entomologists have been sounding alarms over a possible global collapse of insect abundance. In the tropics, climate change, habitat destruction and pesticide use are having clear impacts on insect abundance and diversity. However, a lack of funds and institutional interest is holding back urgently needed research.

Unsung Species: One of Earth’s rarest land mammals clings to a hopeful future (commentary)
- South America’s huemul (Hippocamelus bisulcus) is the Western Hemisphere’s most endangered large land mammal, a fleet-footed Patagonian deer. The species once enjoyed broad distribution, but its numbers have been fractured into roughly 100 small disconnected populations, with huemul totals likely less than 1500 individuals.
- Historically, the huemul was diminished by habitat destruction, poachers, livestock competition and alien predators (especially dogs). More recently climate change may be playing a role, hammering Patagonian coastal fisheries, so possibly causing local villagers to increase hunting pressure on the Andean mountain deer.
- The huemul also suffers from being an unsung species. Unlike the polar bear or rhino, it lacks a broad constituency. If it is to be saved, the species requires broad recognition and support beyond the scientific community. This story is the first in a series by biologist Joel Berger in an effort to make such animals far better known.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Economists, conservationists, political leaders urge adoption of carbon tax to halt tropical deforestation
- A comment piece published in Nature yesterday urges tropical countries to adopt a tax on carbon emissions in order to halt global warming, species loss, and deforestation.
- The authors of the piece include Edward B. Barbier, a distinguished professor of economics at Colorado State University in the US; Ricardo Lozano, Colombia’s Minister of Environment and Sustainable Development; Carlos Manuel Rodríguez, Costa Rica’s Minister of Environment and Energy; and Sebastian Troëng, executive vice-president of US-based NGO Conservation International.
- “Tropical deforestation and land-use change must be halted to safeguard the climate and global biodiversity,” the authors write in Nature. “The widespread adoption of a tropical carbon tax is a practical way forward.”

Cambodian “bat man” bolsters the fight against dengue fever
- Rising temperatures due to climate change allow mosquitoes carrying deadly malaria and dengue fever to live in new parts of the world that were previously uninhabitable, placing over half the world’s population at risk.
- Creating artificial roosts for bats to “farm” their guano can improve soil quality, providing a natural fertilizer while reducing insect numbers, and possibly disease burdens.

Vanishing sea ice in the Arctic could shake up seabird migrations
- Researchers have developed a framework to aid in understanding the changes to seabird migration that could result from the loss of Arctic sea ice due to climate change.
- The team found that one species, the little auk, would expend about half as much energy by shifting its migration from the North Atlantic to the North Pacific, rather than their traditional migration or if they just stayed put in the high Arctic.
- The team also mined the scientific literature and found 29 bird species with the potential for a similar shift in their migratory routes.

World is fast losing its cool: Polar regions in deep trouble, say scientists
- As representatives of the world’s nations gather in Madrid at COP 25 this week to discuss global warming policy, a comprehensive new report shows how climate change is disproportionately affecting the Arctic and Antarctic — the Arctic especially is warming tremendously faster than the rest of the world.
- If the planet sees a rise in average temperatures of 2 degrees Celsius, the polar regions will be the hardest hit ecosystems on earth, according to researchers, bringing drastic changes to the region. By the time the lower latitudes hit that mark, it’s projected the Arctic will see temperature increases of 4 degrees Celsius.
- In fact, polar regions are already seeing quickening sea ice melt, permafrost thaws, record wildfires, ice shelves calving, and impacts on cold-adapted species — ranging from Arctic polar bears to Antarctic penguins. What starts in cold areas doesn’t stay there: sea level rise and temperate extreme weather are both linked to polar events.
- The only way out of the trends escalating toward a climate catastrophe at the poles, say scientists, is for nations to begin aggressively reducing greenhouse gas emissions now and embracing sustainable green energy technologies and policies. It remains to be seen whether the negotiators at COP 25 will embrace such solutions.

Shrinking sea ice in the Arctic opens new pathways for animal disease
- Scientists have discovered that periods of minimal sea ice in the Arctic between 2001 and 2016 were followed by spikes in a deadly disease that affects seals, sea lions and sea otters.
- The team used satellite imagery showing decreases in sea ice combined with GPS collar data tracking animal movements over the 15-year study period.
- After periods of sea ice contraction, the odds that a sampled animal would be affected by the disease were more than nine times higher than typical years.

Carbon emissions from loss of intact tropical forest a ‘ticking time bomb’
- When undisturbed tropical forests are lost the long-term impact on carbon emissions is dramatically higher than earlier estimates suggest, according to a new study.
- Between 2000 and 2013, about 7 percent of the world’s intact tropical forests were destroyed, leading not just to direct carbon emissions but also “hidden” emissions from logging, fragmentation and wildlife loss.
- Another key difference between the old and new estimates is that the latter take into account the diminished carbon sequestration potential of these forests.
- The authors write that the indigenous communities who live in and protect about 35 percent of these forests will have a bigger role to play in the fight against climate change.

Study finds massive reorganization of life across Earth’s ecosystems
- A new study pulls together data from 239 studies that looked at more than 50,000 biodiversity time series.
- The research reveals that almost 30 percent of all species are being swapped out for other species every 10 years.
- The scientists found that the reorganization and loss of species are happening much more quickly in some environments than in others, a finding that could help inform future conservation.

Biodiversity boosts crop pollinators and pest controllers, study finds
- A new study looks at the reliance on biodiversity of ecosystem services provided by pollinating and pest-controlling insects.
- Up to half of the detrimental impacts of the “landscape simplification” that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects.
- The scientists found that the reduction in ecosystem services provided by these insects tended to lead to lower crop yields.

The climate crisis and the pain of losing what we love (commentary)
- World leaders came to the UN last week to decisively tackle climate change again. “This is not a negotiation summit because we don’t negotiate with nature. This is a Climate Action Summit!” declared the UN Secretary-General. But again, global leaders failed and committed to carbon cuts that fall far short of curbing catastrophe.
- In doing so, our leaders committed us to an escalating global environmental crisis that is already unleashing vast changes across Earth’s ecosystems — with many sweeping alterations charted by our scientists, but many other local shifts and absences only noted by those who observe and cherish wild things.
- The loss of familiar weather patterns, plants and animals (from monarchs to native bees) and an invasion of opportunistic living things (Japanese knotweed to Asian longhorned ticks) can foster feelings of vertigo — of being a stranger in a strange land — emotions, so personal and rubbing so raw, they can be hard to describe.
- So I’ve tried to express my own feelings for one place, Vermont, my home, that is today seeing rapid change. At the end of this piece, Mongabay invites you to tally your own natural losses. We’ll share your responses in a later story. This post is a commentary. Views expressed are those of the author, not necessarily Mongabay.

Nature-based climate action no longer ‘the forgotten solution’
- At the Global Climate Action Summit (GCAS) held in San Francisco last year, nature-based solutions to the climate crisis — like keeping forests standing and restoring degraded ecosystems to enhance their carbon storage potential — were referred to as “the forgotten solution.”
- Though conservation of forests and other landscapes could be playing a crucial role in mitigating global climate change, renowned conservationist and UN messenger for peace Dr. Jane Goodall, in a speech delivered last September at the GCAS, said she had personally attended a number of conferences where forests went unmentioned. “Saving the forest is one third of the solution,” Goodall said. “We must not let it be the forgotten solution.”
- That message appears to have been heeded by a number of governments, companies, and civil society groups who committed to major nature-based climate initiatives at the UN Climate Summit held last Monday and the NYC Climate Week that concludes this weekend.

As climate crisis deepens, wildlife adapts, maybe with lessons for us
- Shifts in the timing of lifecycle events, like reproduction or migration, are widely thought to be the most common response of wildlife to global warming.
- In recent years, pikas have been observed modifying their foraging habits in ways that may be behavioral adaptations to a changing climate.
- A long-term study in Kutai National Park on the island of Borneo in Indonesia has shown how extreme weather, brought by the intensifying El Niño Southern Oscillation (ENSO) cycle, is affecting the behavior, habitat requirements, feeding ecology and birth intervals of orangutans.
- Researchers have discovered that African penguins, may be falling into a sort of “ecological trap,” one that humans created through overfishing and climate change.

Slight warming could be enough to heighten risk of malaria: Study
- New research has found that malaria parasites need less time to develop at lower temperatures than previously thought.
- Earlier research postulated that malaria transmission in cooler areas was unlikely because parasites took longer to mature than the lifespans of their mosquito hosts.
- The researchers found that the parasites needed between 31 and 37 days to develop at 18 degrees Celsius (64 degrees Fahrenheit) — substantially lower than the 56 days postulated by previous research and well within the lifespan of female mosquitoes.

Mass die-offs of puffins in Alaska may be linked to climate change
- Between October 2016 and January 2017, the carcasses of hundreds of severely emaciated seabirds, mostly tufted puffins, washed onto the beaches of St. Paul Island, off Alaska.
- Not all birds that die wash up on a beach and are discovered. So the researchers ran an analysis and estimated that between 2,740 to 7,600 tufted puffins died during that time.
- Upon examining the carcasses, the researchers found that the birds had most likely died of starvation linked to shortage in prey triggered by climate change and a warming ocean.

Interest in protecting environment up since Pope’s 2015 encyclical
- New research into the usage of environmentally related search terms on Google suggests that interest in the environment has risen since Pope Francis released Laudato Si’ in 2015.
- Laudato Si’, a papal encyclical, argues that it is a moral imperative for humans to look after the environment.
- Researchers and scholars believe that the pope’s support for protecting the environment could ripple well beyond the 16 percent of the world’s population that is Catholic.

Climate change spurs deadly virus in frogs in the U.K.
- As temperatures climb, ranaviruses cause more frog deaths over a longer part of the year, according to a new study.
- The researchers combined data from outbreaks of disease caused by ranaviruses in common frogs (Rana temporaria) with laboratory investigations.
- They say that shaded areas and deeper ponds could provide refuges for afflicted animals that might slow the spread of the virus, but they also caution that this “short-term solution” is only a stopgap as the warming climate continues to make life difficult for amphibians.

’Unprecedented’ loss of biodiversity threatens humanity, report finds
- The U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services released a summary of far-reaching research on the threats to biodiversity on May 6.
- The findings are dire, indicating that around 1 million species of plants and animals face extinction.
- The full 1,500-page report, to be released later this year, raises concerns about the impacts of collapsing biodiversity on human well-being.

Bird flu in Namibia’s penguins wanes, after killing nearly 500
- More than 450 African penguins, an IUCN-listed endangered animal, have died in an outbreak of bird flu on three islands off the coast of Namibia.
- The virus, H5N8, is thought to have been introduced to the colonies, which hold 96 percent of Namibia’s penguins, by another bird traveling from South Africa, where a similar outbreak occurred in 2018.
- The disease appears to be abating, and researchers are hopeful that the country’s penguins will recover.
- However, they continue to face threats from food shortages caused by overfishing and climate change.

Tapirs could be key in helping degraded rainforests bounce back
- A new study has found that lowland tapirs spend more time in degraded forests than in pristine Amazon rainforest.
- They also defecate and deposit three times more seeds in these degraded areas.
- The results indicate that tapirs may help human-affected forests recover and grow back.

What’s in a name? The role of defining ‘wilderness’ in conservation
- In a recent opinion piece published in the journal Nature, several ecologists question recent efforts to delineate areas of wilderness and intactness around the world to define conservation targets.
- They argue that it would be better to build broadly supported consensus that includes the perspectives of local and indigenous communities.
- But the leader of a team that recently mapped out the remaining wilderness on land and in the ocean said that identifying these areas and developing new targets that incorporate their conservation is critical because current international agreements do not prioritize their protection.

Marine mammal and sea turtle populations benefitting from Endangered Species Act listing
- New research published in the journal PLoS ONE this month finds that the US Endangered Species Act (ESA) is effectively aiding in the recovery of beleaguered populations of marine mammals and sea turtles.
- Marine mammals and sea turtles comprise 62 of the 163 marine species that are currently afforded ESA protections. Researchers collected annual abundance estimates for populations of all 62 of those marine mammal and sea turtle species in order to analyze population trends and the magnitude of observed changes in population numbers.
- The research team hypothesized that populations that have been listed under the ESA for longer periods of time would be more likely to be recovering than those species listed recently, regardless of whether they were listed as “threatened” or the more severe “endangered,” and that’s exactly what they found.

Romeo finally found his Juliet, and an endangered frog has new prospects for survival
- When Valentine’s Day rolled around last year, Romeo found himself without a date. That’s because Romeo is a Sehuencas water frog and, as far as scientists knew at the time, he was the last surviving member of his species. The last time he even bothered calling for a mate was apparently some time in late 2017.
- So last year, the teams at the Museo de Historia Natural Alcide d’Orbigny and the NGO Global Wildlife Conservation set up a dating profile for Romeo on Match.com as a means of raising money to fund an expedition into Bolivia’s cloud forests in search of a Juliet.
- That expedition led to the rediscovery of the Sehuencas water frog in the wild and the collection of three males and two females, all of whom were taken to the Museo de Historia Natural Alcide d’Orbigny’s K’ayra Center for Research and Conservation of Threatened Amphibians. Once the quarantine period is over, Romeo will finally meet his Juliet — and the species just might make a comeback from the brink of extinction.

A ‘FitBit for squid’ could help track the ocean’s squishier species
- The ITAG, a neutrally buoyant sensor device for soft-bodied invertebrates, is currently in development through joint research at Woods Hole Oceanographic Institute and Monterey Bay Aquatic Research Institute.
- The device has shown success in tracking animals such as squid and jellyfish as they respond to environmental changes.
- The casing is 3D printable, and the electronics array will be open-sourced, so scientists may quickly develop tracking devices for other marine invertebrates previously difficult to monitor.
- The current ITAG versions are smaller and more easily retrievable than a 2015 prototype, but researchers are still working to bring the size down and the retrieval rates up.

Rapid population drop weakened the Grauer’s gorilla gene pool
- The loss of 80 percent of all Grauer’s, or eastern lowland, gorillas in the past two decades has led to a severe reduction in the subspecies’ genetic diversity, new research has found.
- That slide could make it more difficult for the fewer than 4,000 remaining Grauer’s gorillas to adapt to changes in their environment.
- Scientists look for signs of hope in the animal’s sister subspecies, the mountain gorilla, which, studies suggest, has adapted to its own low levels of genetic diversity.

COP24: Green groups warn of pitfalls in ‘forests for climate’ deal
- A declaration to protect and use forests as a tool to combat climate change has been lambasted by environmentalists.
- The declaration, initiated by the Polish government during the COP24 climate summit, could promote the burning of wood pellets for bioenergy, the environmentalists warn.
- Wood-based biomass is a controversial and hotly debated topic in climate discussions, with scientists finding it emits up to 50 percent more CO2 than coal. But its proponents, including the U.S. EPA, champion it as a “carbon neutral” source of energy.

Photos highlight evolving roles of AI, citizen science in species research
- A recent observation by an amateur naturalist of a fiddler crab species hundreds of kilometers north of its known range challenged the complementary strengths of computer vision and human expertise in mapping species distributions.
- The naturalist uploaded this record to the iNaturalist species database used by amateurs and experts to document sightings; expert input correctly identified the specimen after the platform’s computer vision algorithms did not acknowledge the species outside its documented range.
- Citizen naturalist observations can be used to document rapid changes in species distributions. They also can improve modeling and mapping work conducted by researchers and play an increasing prominent role in building environmental databases.

Birds on Broadway: A Q&A with the Audubon Mural Project’s Avi Gitler
- A public art project is bringing new bird life to uptown Manhattan in John James Audubon’s old neighborhood in New York City.
- The Audubon Mural Project is an ongoing collaboration between the National Audobon Society and Gitler &____ Gallery. So far, 80 murals of 101 bird species have been painted, spanning 133rd to 165th street on Broadway. The project will eventually end at 193rd street, at the end of Audubon Avenue.
- In this Q&A, Avi Gitler, co-producer of the Audubon Mural Project and founder of Gitler &____ Gallery, talks about the impetus for the public art project, which focuses on birds threatened by climate change, how he has enlisted the participating artists, and what he hopes public art about climate change-threatened birds can achieve.

It’s time to strengthen the macroecology–conservation practice interface (commentary)
- Imagine being able to know how many individual organisms occur at any given time across areas as large as whole continents or even the entire globe. Though satellites may one day enable us to obtain this information directly, a sub-discipline of ecology — macroecology — currently represents the main tool to generate those estimates.
- With biodiversity under increasing pressure from human activities, macroecology can contribute greatly to the scientific evidence base for national and international decisions aimed at conserving biodiversity and ensuring a safe future for our planet.
- Yet, examples of macroecological research directly supporting conservation decisions remain rare. Why does a sizeable macroecology-conservation practice gap persist?
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

New picture of coral reef health opens avenues for saving them
- New research has identified five potential phases, or “regimes,” of coral reef health, helping scientists and ecosystem managers better assess the condition of reefs.
- The study also revealed that certain transitions from one phase to another were more likely to result from human-induced changes to the ocean.
- The authors of the study say the research could help identify new opportunities to save and improve the health of reefs.

Deforested, degraded land restoration a top priority for African leaders
- African leaders met at a summit to discuss land restoration across the continent on Nov. 13, ahead of the U.N. Biodiversity Conference in Sharm-El-Sheikh, Egypt.
- Representatives from several African countries shared their countries’ pledges to restore hundreds of thousands of square kilometers of degraded and deforested land in the coming decades.
- The summit’s leaders said they hoped the deliberations during the day-long summit would help African countries in both their contributions to international targets and to the improvement of their natural ecosystems for the benefit of their citizens.

Call to protect dwindling wilderness ‘before it disappears forever’
- Just 23 percent of wilderness on land and 13 percent of wilderness at sea remains, according to new maps of global human impacts.
- Five countries — Russia, Canada, Australia, the United States and Brazil — contain 70 percent of the remaining wilderness.
- The authors of the suite of studies argue that wilderness protection should move to the forefront of the conservation agenda.

Tsetse fly numbers dwindle in the warming Zambezi Valley
- Tsetse flies carry the microorganism that causes sleeping sickness in humans and livestock, but a recent study reveals that their numbers have dropped at a site in the Zambezi Valley as temperatures have climbed.
- Sleeping sickness, known also as trypanosomiasis, is a debilitating and potentially deadly disease to humans that also kills perhaps 1 million cattle each year.
- The study’s authors say that the decline of the tsetse in Zimbabwe’s Zambezi Valley might be accompanied by a rise in their numbers in cooler locales where they once weren’t as prevalent.

Women’s work in Senegalese conservation includes exorcising demons
- Women, and older women in particular, play important roles in the Kawawana ICCA, an indigenous conservation group in Senegal’s Casamance region.
- They set rules for oyster harvesting and mediate conflicts that arise with outsiders who infringe upon Kawawana rules.
- They also deploy ancient animist traditions in defense of the local environment and act as spiritual doctors for those who break the rules.
- Since 2010, Kawawana has made huge strides in repopulating the local river with fish, reducing damaging levels of salinity in its waters, and halting deforestation, largely by returning to traditional fishing and forestry practices.

Scientists urge world leaders to scale up ambitions to protect global biodiversity
- Research has shown that a sixth mass extinction event is underway and largely driven by human activities. With the global population set to balloon to 10 billion people by 2050, which will more than double the current demand for food and water, scientists are increasingly calling for mankind to set aside sufficient amounts of ecosystems on land and at sea to ensure the survival of the many species with which we share planet Earth.
- Yet, according to Jonathan Baillie, Executive Vice President and Chief Scientist of the National Geographic Society, and Ya-Ping Zhang, Vice President of the Chinese Academy of Sciences, “Current levels of protection do not even come close to the required levels.”
- To preserve global biodiversity and safeguard the provision of critical ecosystem services, ambitions must be ratcheted up in 2020, when the world’s governments will meet at the Convention on Biological Diversity in Beijing, China to set biodiversity targets for the future, Baillie and Zhang argue.

Dress like a polar bear: learning to love muskoxen at 15 below zero
- Enduring subzero temperatures that make your face freeze, dressing as a bear, and getting chased by an angry male muskox, are all in a day’s work for biologist Joel Berger. His experiences and scientific insights are featured in a new book that focuses on the lives and survival strategies of muskoxen and other cold-adapted animals.
- The autobiographical book, “Extreme Conservation: Life at the Edge of the World,” profiles Berger’s studies of inhospitable ecosystems, ranging from the high latitudes above the Arctic Circle, to the Himalayas and Tibetan Plateau.
- Mongabay contributor Gloria Dickie interviews Berger to see what makes a human want to live and work in some of the Earth’s most brutal environments. The quick answer: to see how barely studied Northern and alpine large mammals — especially muskoxen — are adapting, or not adapting, to a rapidly warming world.
- Berger’s findings regarding instinctual and learned behavior, evolution and survival in a globally warmed world turn out to be revelatory not only to cold-adapted animals, but also relevant to wildlife species around the globe — and to the scientists who want to conserve them.

Audio: The ‘Godfather of Biodiversity’ on why it’s time to manage Earth as a system
- On this episode we welcome the godfather of biodiversity, Dr. Thomas Lovejoy, to discuss some of the most important environmental issues we’re currently facing and why he believes the next decade will be the “last decade of real opportunity” to address those issues.
- Lovejoy joined the Mongabay Newscast to talk about how deforestation and the impacts of climate change could trigger dieback in the Amazon and other tropical forests, causing them to shift into non-forest ecosystems, as well as the other trends impacting the world’s biodiversity he’s most concerned about.
- He says it’s time for a paradigmatic shift in how we approach the conservation of the natural world: “We really have got to the point now where we need to think about managing the entire planet as a combined physical and biological system.”

Diverse family of algae could help corals survive warming seas
- Scientists have found that some algae that associate with corals are much more diverse and much older than previously thought.
- The origin of certain algae occurred at around the same time corals began building reefs on a grand scale around the world, the researchers showed.
- The diversity of these algae could boost corals’ resistance to higher ocean temperatures.
