For drought relief, Cordilleran women in the Philippines rely on seed saving
- As El Niño and climate change bring drought to the northern Philippines, farmers say the value of local heirloom seeds shines through.
- Farmers say these seeds, cultivated through generations, show greater resilience to drought and heat than commercial hybrid seeds promoted by the government.
- A network of seed savers, spearheaded by rural women, is working to revitalize the traditional practices of saving seeds, combining traditional agricultural knowledge with modern documentation processes.

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.

Bangladeshi farmers find zucchini’s high yields & low costs palatable
- Though long considered “foreign” to Bangladeshi farmers, zucchini squash is now cultivated among growers who value its high productivity, lower production cost and short growing time.
- Farmers living in dry regions and river islands prefer to cultivate this vegetable, where watering the plant is an issue.
- Bangladesh Agricultural Extensions expects more zucchini squash cultivation in the coming days based on farmers’ enthusiasm and growing local demand in the market.

Rocky rollout for Bangladesh’s ambitious solar-powered irrigation plans
- Nearly half of irrigation costs in Bangladesh are due to irrigation, and the diesel pumps that currently power irrigation networks are responsible for 1.6% of the country’s greenhouse gas emissions.
- To address both issues, the government is rolling out a nationwide program to gradually replace these diesel pumps with solar-powered ones, aiming to slash irrigation-related emissions by 0.8 million metric tons by 2030.
- It also says that given that irrigation use is concentrated in the non-monsoon months, the surplus energy generated by the pumps the rest of the time can be fed into the grid, providing up to 480 gigawatt-hours of clean energy a year.
- In pilot programs, however, farmers have expressed concern over the reliability of the solar pump systems, especially for water-intensive crops such as rice and corn, and have also noted that their irrigation costs remain the same.

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 largest ever study, Indigenous and local communities report the impacts of climate change
- Indigenous peoples and local communities are reporting a series of tangible and nuanced impacts of climate change, according to a new study.
- The study collected 1,661 firsthand reports of change in sites across all inhabited continents and aggregated the reports into 369 indicators of climate change impacts, including changes in precipitation, plant cultivation and marine ecosystems.
- Existing measures to track climate change impacts are barely able to relate to the diverse and complex ways in which local people experience and observe environmental changes, according to the authors. For instance, instrumental measurements might capture changes in rainfall patterns but miss crucial relationships between climate change awareness, sensitivity and vulnerability.
- This research constitutes the largest global effort by Indigenous peoples and local communities to compile and categorize local observations of climate change and its impacts.

In highly urbanized Japan, city farmers are key to achieving organic goal
- The Japanese government aims to convert at least 25% of all its farmland to organic by 2050, a significant jump from just 0.5% in 2020.
- Researchers found that urban and semi-urban farmers in Tokyo tend to adopt environmentally friendly practices more often than rural farmers, in response to a more environmentally conscious populace, a greater number of organic food stores and restaurants, and freedom from pressure to conform with farming practices in rural communities.
- Japan’s urban farmers are also more likely to diversify their business, such as by engaging in direct sales and creating hands-on farming events or volunteer opportunities, strengthening their ties with the local community.
- Despite positive steps, agricultural land in Tokyo continues to shrink, mirroring a trend in declining biodiversity. Advocates say continued efforts will be needed to preserve and make the best use of the capital’s urban farms.

New U.S. agroforestry project will pay farmers to expand ‘climate-smart’ acres
- The Nature Conservancy is leading the Expanding Agroforestry Project to provide training, planning and funds for 12,140 hectares (30,000 acres) of new agroforestry plantings in the U.S.
- Goals for the program include enrolling at least 200 farmers, with a minimum of 50 from underserved communities.
- Initial applications have surpassed expectations — 213 farmers applied in the first cycle with 93% coming from underserved populations.
- The first round of payments is set for distribution in fall 2024.

‘Planting water, eating Caatinga & irrigating with the sun’: Interview with agroecologist Tião Alves
- In an interview with Mongabay, Brazilian agroecologist Tião Alves tells how he has been teaching thousands of rural workers to survive in the Caatinga biome, severely afflicted by drought, climate change and desertification.
- At the head of Serta, one of the most important agroecology schools in the Brazilian Northeast, he teaches low-cost technologies that ensure food security with a minimum of resources, both natural and financial.
- Currently, 13% of the Caatinga is already in the process of desertification, the result of a combination of deforestation, inadequate irrigation, extreme droughts and changes in the global climate.

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.

Fertilizer management could reduce ammonia pollution from 3 staple crops: Study
- Nitrogen fertilizers are applied to crops to increase yield, but some of that nitrogen is lost to the atmosphere in the form of ammonia. Ammonia is a major air pollutant linked to numerous health issues, including asthma, lung cancer and cardiovascular disease.
- Using published agricultural and environmental data, researchers employed machine learning to quantify global ammonia emissions from rice, wheat and corn cultivation at 10-kilometer resolution. This added up to a global estimate of 4.3 billion kilograms (9.5 billion pounds) of ammonia emitted from the three staple crops in 2018.
- The model also revealed that optimizing fertilizer management to suit local conditions could achieve a 38% reduction in global ammonia emissions from the three crops. Optimal fertilizer management and the associated emissions reductions depended on local climate and soil characteristics.
- The model, which utilized machine learning, found that under current fertilizer management practices, climate change will increase ammonia emissions from rice, wheat and corn by up to 15.8% by 2100. But this increase could be entirely offset by optimizing fertilizer management and adapting it to local conditions.

Climate change brews trouble for tea industry, but circular solutions await
- In its many varieties, tea is renowned as one of the world’s most consumed beverages, second only to water.
- Like many other agricultural crops, tea production impacts the environment: Production in tropical countries is implicated in deforestation, pollution and impacts on fragile biodiversity.
- Climate change imperils the tea industry, threatening to reduce yields and hammer millions of smallholder farmers who derive their livelihood from the crop.
- Experts say circular solutions can help build resilience in tea production against climate change, while at the same time lessening its environmental impact.

Java rice farmers suffer crop failure as copper mine pollutes local irrigation
- Rice farmers in Cokrokembang village, East Java province, suspect contamination from a nearby copper mine operated by PT Gemilang Limpah Internusa is to blame for recent crop failures.
- Water pollution from the mine is visible in the Kedung Pinihan River, while tests conducted by the local government reveal levels of copper compounds far exceeding environmental standards.
- Despite attempts to address the issue, including government involvement and remedial measures by the company, farmers like Parno continue to suffer declining yields, prompting calls for compensation for affected farmers.

Breadfruit’s low carbon storage could be offset by fast growth, study finds
- Breadfruit, a perennial tropical tree that produces large, carbohydrate-rich fruit, has been put forward by advocates as a climate solution as well as a way to strengthen food security; but the carbon storage potential of breadfruit has never before been investigated.
- In a new study, researchers from the University of Hawai‘i at Mānoa found that in orchards, breadfruit’s carbon storage abilities are relatively low compared with other broadleaf trees in wet environments.
- However, the authors say breadfruit compensates for this with a fast growth rate and may be better served as building blocks for agroforestry plots that can sequester even more CO₂; more research is required to understand the full potential of breadfruits in a sustainable system.

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.”

Harsh dry season sours harvest prospects for Java coffee farmers
- Indonesia is the world’s fourth-largest producer of coffee, after Brazil, Vietnam and Colombia, but the archipelago’s farmers are less productive than their competitors.
- In East Java province, farmers have seen yields plummet as a protracted water deficit shrinks fruit and introduces pests.
- Total output is expected to drop by more than 20% this season, while increasingly frequent extreme weather may pose challenges to the viability of some smallholders in lowland areas of Indonesia.

Climate change, extreme weather & conflict exacerbate global food crisis
- Global food insecurity has risen substantially since pre-pandemic times, exacerbated by extreme weather, climate change, war and conflict.
- What the U.N. World Food Program calls “a hunger crisis of unprecedented proportions” plays out differently around the world.
- In this story, three of Mongabay’s Y. Eva Tan Conservation Reporting Fellows detail the local situation in their region – from rising inflation and flooding in Nigeria to diminished local food production in Suriname and the environmental and socioeconomic effects of commercial food production in Brazil.
- “If we do not redouble and better target our efforts, our goal of ending hunger, food insecurity and malnutrition in all its forms by 2030 will remain out of reach,” write the authors of the U.N. Food and Agriculture Organization (FAO) 2023 report on global food security and nutrition.

In Bangladesh, sunflower grows where other crops don’t amid increasing salinity
- The changing climate, rising sea levels and other anthropogenic factors are forcing a vast area of Bangladesh’s coastal zone to remain barren due to the presence of salinity in arable land.
- Overcoming these hurdles, coastal farmers, with the support of the government and various nongovernmental organizations, are now farming sunflowers and benefiting from the alternative crop.
- Bangladesh currently produces only 10% of the oilseeds it uses; imports from different countries meet the rest of the demand.
- The government estimates that the country could produce sunflower to meet the local demand for cooking oil by up to 26% by cultivating the oilseed in saline-prone zones.

Maluku farmers sweat El Niño drought as Indonesia rice prices surge
- Rice prices surged across Indonesia during the second half of 2023 as the effects of El Niño led to widespread crop failures.
- In December, President Joko Widodo ordered military personnel to help farmers plant rice in a bid to boost domestic production, and curb food price inflation.
- On Buru Island, Mongabay Indonesia spoke with farmers who described risks of conflict as water scarcity forced farmers to queue for access to water.

We need a better understanding of how crops fare under solar panels, study shows
- In agrivoltaics, farmers grow crops beneath or between solar panels.
- Proponents say the technology can help achieve clean energy goals while maintaining food production, but experts caution that careful analysis and guidelines are needed if we’re not to compromise agricultural production.
- A new synthesis of previously published studies finds that overall crop yields decline as the amount of land covered by solar panels increases.
- This ground cover ratio is a convenient, easily measured and reproducible metric that can be used to predict crop yields and better evaluate agrivoltaic systems.

In Mexico, Xalapa’s chronic water scarcity reflects a deepening national crisis
- Residents of Xalapa, the capital of Veracruz, Mexico, have been struggling with a worsening water shortage that often leaves people without daily access to household water for washing.
- The problem is nationwide, in 30 of 32 states, forcing residents to purchase and recycle water and postpone bathing.
- Experts have blamed climate change and extreme heat for the country’s water shortages; others also blame corruption that allows companies to pay for unlimited water use.
- Deforestation for development, an increase in construction and building and population increases are also factors.

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.

Agricultural nitrogen pollution is global threat, but circular solutions await
- Nitrogen is an essential element for living organisms, needed to build DNA, proteins and chlorophyll. Although nitrogen makes up nearly 80% of the air we breathe, it’s availability to plants and animals is extremely limited. As a result, nitrogen has been a limiting factor in crop growth since the dawn of agriculture,
- Humanity shattered those limits with the Haber-Bosch process to make ammonia and synthetic fertilizers, driven by fossil fuels, and now used in vast amounts on crops. But that nitrogen influx has disrupted Earth’s natural nitrogen cycle. Today, nitrogen pollution is causing overshoot of several planetary boundaries.
- Nitrates pollute waterways, causing eutrophication. Nitrous oxide is a powerful greenhouse gas and an ozone-depleting substance. Ammonia is a cause of air pollution, with severe health impacts. Nitrogen is also used to produce potentially long-lived synthetic substances that themselves can become pollutants.
- Better agricultural management and technology could cut a third or more of nitrogen pollution. Circular economy solutions include better fertilizer efficiency, enhanced natural nitrogen fixation, and recovery and reuse of wasted nitrogen. Societal changes are also needed, including a shift in human diet away from meat.

A Mekong island too tiny for industrial farming now points to Vietnam’s future
- In the decades following the U.S. war in Vietnam, the Vietnamese government championed intensive farming methods that boosted rice harvests and turned the country into an export powerhouse.
- While much of the Mekong Delta was reshaped to support intensive farming, the coastal island of Con Chim was deemed too small to be worth installing the necessary dikes and sluice gates, leaving farmers there to continue traditional patterns of wet and dry season agriculture and fishing.
- Now, in an era dominated by climate concerns, Vietnam plans to scale back rice farming and shift to more nature-based agricultural practices. Once a forgotten backwater, Con Chim now stands as a rare guidepost to a more sustainable agricultural future.
- This story was produced in partnership with the Global Reporting Program at the University of British Columbia’s School of Journalism, Writing, and Media.

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.

In Brazil’s Caatinga, adapted agroforests are producing food from dry lands
- In northeastern Brazil, the model known as Agrocaatinga has proven to be the most productive and effective in increasing food security for families, generating income and preserving native vegetation.
- Previously degraded lands now produce around 50 types of food, thanks to the combination of an agroforestry system with rainwater harvesting techniques.
- Agrocaatingas emerged from the commercial demand for wild passion fruit, a native fruit that today yields up to $600 per harvest for families — four times the local per capita monthly income.

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.

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.

Amazon women create sweet business success with wild, vitamin-C packed fruit
- A women’s group in Colombia’s Amazon is successfully leading a sustainable, and profitable, business by harvesting camu-camu, an acidic wild fruit with more vitamin C than an orange or lemon.
- The business has been able to produce four to 14 tons of fruit pulp per year for sale around the country, while sustainably managing the plant species’ population.
- The women played a pioneering role in Colombia by showing that non-timber forest resources could be used to generate income in areas of protected rainforest.
- The sustainable use of such resources has become a successful conservation strategy that has received praise from scientific institutes and environmental authorities.

Battling desertification: Bringing soil back to life in semiarid Spain
- Southeastern Spain is experiencing the northward advance of the Sahara Desert, leading to declining rainfall, soil degradation, and climate change-induced droughts, threatening agricultural lands that have been farmed for many centuries.
- Local farmers recently began adopting regenerative agriculture practices to better withstand long, persistent droughts punctuated by torrential rains and subsequent runoff.
- Many farmers in the region have formed a collaborative group called Alvelal to address encroaching desertification, depopulation, and the lack of opportunities for youth.
- Alvelal members manage more than 15,000 hectares (37,000 acres) of farmland using regenerative agriculture techniques and aim to expand further, conserving more farmland against the onslaught of climate change, while restoring natural corridors and promoting biodiversity.

Kenya’s Lake Victoria floods leave orphaned children to run their households
- Beginning in 2019, devastating floods on the shores of Kenya’s Lake Victoria have inundated homes, displaced families and left some orphaned children in charge of caring for their siblings and running the household.
- Many families continue to live in makeshift camps, hoping to rebuild and renew their lives; the effects of the flooding have been particularly harsh on children who have had to drop out of school or work to ensure the family’s survival.
- Experts attribute the floods to a combination of factors, including climate change, increased rainfall and lack of vegetation to control runoff; in 2015, an international research team predicted swiftly rising waters that could harm the region.
- UNICEF reports a concerning increase in the number of children affected by flooding in recent years, as climate change leads to more crises that can disrupt education, destabilize families and leave long-term effects on child development and psychosocial well-being.

An ‘aquatic moonshot’ in Vietnam aims to fight livestock methane with seaweed
- Scientists from the R&D company Greener Grazing aim to reduce global greenhouse gas emissions by growing and marketing a red seaweed (Asparagopsis taxiformis) as an additive for livestock feed.
- Worldwide, some 3 billion cattle and sheep produce roughly 231 billion pounds of methane annually; researchers estimate some 100 million tons of A. taxiformis would be needed to eliminate 98% of those emissions, a figure that’s roughly three times current global production of all seaweeds.
- Greener Grazing is experimenting with growing A. taxiformis in central Vietnam’s Van Phong Bay, but there are challenges.
- Skeptics also say the benefits of seaweed are limited in both the amount of methane that can be reduced as well as the capacity for scaling production to meet the size of the problem.

Seaweed: The untapped economic potential for Bangladesh
- Bangladesh currently produces some 400 tons of seaweed, valued at 55 million taka (about $500,000), while a study suggested the country could produce 50 million tons of seaweed annually by 2050.
- Despite the potential to grow and earn more foreign currency through export, the sector is dealing with a number of difficulties, including inadequate investment as well as proper guidelines and regulations.
- According to the Food and Agriculture Organization (FAO), seaweed farming is one of the fastest-growing aquaculture sectors globally, with an annual production of about 33 billion tons, valued at $11.8 billion.

Salinity hinders Bangladesh agriculture; groups respond with seeds & information
- Bangladesh is the fourth-highest rice-producing country in the world, but much of that production is threatened by salinity.
- More than 30% of the cultivable land in Bangladesh is in the coastal area; a comparative study of the salt-affected area showed that of 2.86 million hectares (7.1 million acres) of coastal and off-shore lands, about 1.056 million hectares (2.6 million acres) — an area roughly the size of Lebanon — of arable lands are affected by varying salinity, hampering agricultural production.
- In the coastal zones, farmers mainly cultivate low-yielding, traditional rice varieties during the wet season, while in the dry season (January- May), most of the land remains fallow because of soil salinity.
- To cope with the situation, government and nongovernmental organizations are introducing different types of saline and extreme weather-tolerant crop varieties to use the farmland yearly.

Indigenous peoples undersupported on frontline of hotter, drier, fiery world
- It’s official: This has been the warmest June-July-August on record, and much attention has focused on the urgent need to achieve climate resilience in impacted urban areas. But how are rural Indigenous communities around the world living with these new extremes?
- Indigenous peoples — from Africa to the Arctic to Central America — report unprecedented heat waves, droughts, storms and wildfires, extremes that are impacting the wildlife they hunt, the plants they gather, crops they grow, livestock they raise, and their very survival.
- Given that many Indigenous peoples live close to the land and depend directly on local resources, they’re especially vulnerable to the massive changes now sweeping our planet.
- But while Indigenous peoples are considered by many researchers and activists to be Earth’s best land stewards, their communities aren’t receiving the funding or resources necessary to adapt to a hotter, drier, stormier, fiery world, often due to the lack of access to their traditional lands.

DRC food sovereignty summit yields support for agroecology, local land rights
- The Alliance for Food Sovereignty in Africa (ASFA) recently held a meeting in Kinshasa to argue for the reorienting of food production around agroecology in the Congo Basin.
- Civil society groups, donors, government representatives and small-scale farmers gathered to exchange views on challenges and solutions to food security.
- Across Africa, agricultural policy is geared toward greater reliance on large-scale farms and mechanization, commercial seeds, pesticides and synthetic fertilizer.
- A declaration issued at the close of the summit instead called for investment in agroecological methods, as well as recognition of and protection for Indigenous and local peoples’ land rights.

Agroecology alliance calls for more food at less cost to nature in Congo Basin
- The Alliance for Food Sovereignty in Africa (AFSA) will make the case for reorienting food production systems and agricultural policy at a meeting in Kinshasa from Aug. 29-31.
- Food security across the Congo Basin is threatened by impoverished soils, climate change, and displacement due to armed conflict, forum attendees say.
- Governments in the region back improved seeds and synthetic fertilizer for small-scale farmers as well as large-scale agriculture projects to boost yields and revenue.
- AFSA argues these strategies cause more harm than good to both farmers and forests, and calls for a turn to agroecological methods instead.

Bali rice experiment cuts greenhouse gas emissions and increases yields
- Rice paddies are responsible for 11% of the world’s methane emissions. There are more than 200 million rice farms in Asia.
- Working with local farmers, researchers in Bali, Indonesia, have discovered how to dramatically reduce the greenhouse gas emissions output of rice fields. Initial indications are showing a 70% reduction.
- The farming breakthrough also boosted the yield of crops and reduced the amount of pesticides flowing to coral reefs.

In Philippines, climate change tests Indigenous farming like never before
- In the uplands of the Philippines’ Iloilo province, Indigenous Suludnon farmers maintain deep connections to the agroecosystem that has sustained their community for generations.
- Agroforestry systems and diversified planting have helped the Suludnon cope with a changing climate, and traditional knowledge of natural signs of hazardous weather have allowed them to prepare for storms.
- However, with climate change bringing increasingly frequent extreme weather events, along with crop pests and disease, the Suludnon’s time-refined methods are coming under strain.

Morocco rolls out a phosphorous-fueled plan to heal soils across Africa
- Farmers across Africa are faced with eroded, phosphorus-limited soils, leading to low crop yields, despite having some of the world’s richest phosphate deposits in Morocco.
- Soil scientists at Mohammed VI Polytechnic University in Morocco are building a countrywide network of farmers and soil experts to routinely test soil for its nutrients and other properties, giving farmers more tailored fertilizer recommendations.
- Morocco is the first country in Africa to create soil fertility maps, a way to map out the productivity of arable land, with the practice now catching on in other countries.
- Researchers and others in the agriculture sector see Morocco as a potential leader in boosting soil productivity and revolutionizing agriculture in Africa to expand production beyond subsistence farming.

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.

Philippines’ largest freshwater wetland and Indigenous livelihoods face multiple threats
- The floating community of the Manobo Indigenous tribe depend on the rise and fall of water in the Philippines’ Agusan Marsh; however, the marsh faces challenges that threaten its ecosystem and the lives of the people who depend on it.
- Development projects, locals and others moving into the fertile region are burning and draining the peatlands and swamp forests for conversion into farmland.
- The continued expansion of agricultural areas in the Agusan Marsh, known as the Philippines’ least-disturbed freshwater wetland, has changed habitats in the basin and, with land use conversion, fragmented ecosystems.
- A recent study published in the journal Nature found extensive global wetland loss over the past three centuries due to various causes, including similar ones seen in the Agusan Marsh.

Vietnamese rice farmers go high-tech to anticipate a low-water future
- Since the 1970s, Vietnam’s “rice-first” policy facilitated the construction of an elaborate series of dikes and dams that allowed farmers in the Mekong Delta to flood their fields to allow for multiple harvests per year.
- Now, in the face of climate change impacts, seawater intrusion, upstream dams and new government policies that mandate water conservation, farmers in the delta need to find ways to reduce their water consumption.
- In one pilot project, university researchers have teamed up with local farmers to implement a technique called alternate wetting and drying (AWD), supported by a smartphone application that allows farmers to save water and reduce emissions.

Breadfruit: A starchy, delicious climate and biodiversity solution
- Originally from Southeast Asia, breadfruit trees produce large, potato-like fruits that can be used in many different culinary applications, making this a reliable crop for places struggling with poverty and food security.
- According to recent research, the increased temperatures of climate change will widen breadfruit’s range, especially in Sub-Saharan Africa.
- A few small organizations have been working to spread breadfruit trees around the world by encouraging farmers to plant breadfruit alongside other food crops in agroforestry plots. NGOs say this style of planting not only increases food security but makes these food systems even more resilient to climate change.

Can Spain keep the rising sea from washing away a critical delta?
- One of Europe’s most important deltas, a vital wildlife sanctuary and economic engine, is facing a myriad of threats stemming from climate change and water management.
- Rising sea levels and stronger storms are washing away the very sediment that constitutes the Ebro Delta and sending saltwater far inland.
- The government plan to bolster the delta relies heavily on trucking sediment to its exposed outer banks, but it’s a stop-gap measure until researchers can develop a more sustainable long-term solution.
- The question is: Can they find one in time?

Climate emergency may channel millions in resources toward corn-based ethanol in the Amazon
- An agribusiness magnate from the U.S., who is already the biggest producer of corn-based ethanol in Brazil, plans to leverage “green” investments from governments and banks to meet negative carbon emissions using an unproven method.
- His company is trying to implement in the Brazilian state of Mato Grosso a copy of his Midwest Carbon project, an initiative that plans to capture 12 million tons of carbon in ethanol plants and store them in North Dakota, below ground.
- Even though the company alleges that it is rigorously controlling the environmental practices of its corn suppliers in Brazil, an investigation found that the local executives are themselves connected to illegal deforestation in Mato Grosso.

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.

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.

In Senegal, rice intensification helps farmers grow more with less
- To fight food insecurity and climate change, Senegal is increasingly employing a relatively new strategy for growing rice, known as the “system of rice intensification” (SRI).
- Developed in Madagascar in the 1960s, this method of growing rice intentionally stresses the plants, which allows the farmer to use less water, improves soil fertility, decreases methane emissions, and, most importantly, increases yields.
- Critics of the method say it’s more a list of principles than set rules, with some farmers also turning to herbicides to deal with weeding.
- Still, the method has been scientifically shown to provide numerous benefits for growing rice in drier climates.

Deforestation linked to less rainfall, study shows; El Niño could make it worse
- A new study shows concerning links between deforestation and reduced precipitation in tropical regions, which can in turn lead to reduced agricultural yields and food security issues.
- Now, researchers are concerned about the potential for another El Niño, which typically brings hotter, drier conditions to tropical regions, particularly in Southeast Asia, and can compound the effects of deforestation and reduced rainfall.
- The 2015-16 El Niño triggered crop losses, disease outbreaks, malnutrition and food insecurity, livestock deaths and other hardships that affected 60 million people globally; researchers say these trends signal the need for greater climate resilience in local communities.

In Indonesia, clouds form over East Java’s promising band of avocado growers
- Global avocado production is rising to meet demand from increasingly health-conscious consumers.
- South and Central American producers remain the world’s largest, but production in Indonesia is rising quickly.
- Farmers have found new ways to increase value, but research shows rising temperatures and increased rainfall threaten to undermine productivity.

Organic farming, and community spirit, buoy a typhoon-battered Philippine town
- After their town was devastated by floods in 2004, residents of Kiday in the Philippines shifted to organic methods when rebuilding their farms.
- Today, the Kiday Community Farmers’ Association practices agroecology and agroforestry, maintaining communal plots as well as private gardens.
- The association receives nonprofit support, but government funding continues to prioritize conventional agriculture over more sustainable methods.
- Farmers in Kiday also face a new threat in the form of the government-supported Kaliwa Dam, which is under construction upstream of the village.

‘Alarming’ heat wave threatens Bangladesh’s people and their food supply
- Temperatures across Bangladesh have hit record highs as the country swelters in the heat wave currently sweeping across much of Asia.
- Dhaka recorded its highest temperature in six decades this month, at 40.6°C (105.1°F), with meteorologists warning that heat waves like this are becoming more common.
- The heat also threatens the country’s all-important rice crop, with the government advising farmers to ensure sufficient irrigation to prevent heat shock to their plants.
- With the heat now easing, a new fear has emerged: Cooler temperatures signal the start of the monsoon, which, in the northeast region of Bangladesh often means floods that can also destroy rice crops.

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.

Amid changing climate, Bangladesh farming groups conserve indigenous rice seeds
- Bangladesh, the fourth biggest rice-producing country in the world, produces around 39 million tons of rice annually to feed its 170 million people, with 130 lab-developed high-yielding varieties.
- For higher production, farmers have turned to a few high-yielding varieties, despite having around 1,000 indigenous varieties that have better adaptive quality amid changing climatic patterns; the trend has forced many traditional varieties to go extinct.
- By cultivating indigenous rice varieties, some farmers are fighting back against monoculture, and a few nongovernmental conservation organizations, as well as individuals, are creating awareness about protecting local varieties.
- Bangladesh Resource Center for Indigenous Knowledge (BARCIK) alone is conserving more than 600 local rice varieties and engaging with farmers across the country.

Fish kills leave Kenya’s Lake Victoria farmers at a loss, seeking answers
- According to a Kenyan government report, fish farmers in sections of Lake Victoria lost more than 900 million Kenyan shillings ($7.2 million) in massive fish kills in November 2022.
- Scientists attribute the fish kills to reduced levels of dissolved oxygen likely due to a natural phenomenon called upwelling, which can be exacerbated by climate change and extreme weather.
- Local farmers who lost their fish, however, attribute the die-offs to pollution from Lake Victoria industries, which agencies have accused of discharging untreated effluent into the lake in recent years.

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.

For Dutch farming crisis, agroforestry offers solutions: Q&A with Lennart Fuchs & Marc Buiter
- The Dutch government aims to halve nitrogen emissions by 2030 by downsizing and closing farms, sparking a wave of farmer protests and a surprising win for a new agrarian political party.
- Agricultural and environmental experts are calling for the need to introduce food system solutions that both address farmer livelihoods while tackling the climate and environmental crises.
- Agroforestry, agroecology and silvopasture — climate change and conservation solutions that can be profitable — are among the solutions they say can contribute positively to the country’s nitrogen goals.
- Mongabay spoke with two Dutch agricultural experts — Lennart Fuchs from Wageningen University & Research, and Marc Buiter from the Dutch Food Forest Foundation — on how agroforestry could be part of a solution that works for both farmers and the environment.

Companies eye ‘carbon insetting’ as winning climate solution, but critics are wary
- A tool that wields the techniques of carbon offsets is surging among companies claiming that it reduces their carbon footprints. The tool, known by some as “insetting,” had simmered for more than a decade on the fringes of climate action among brands that rely on agriculture, but is now expanding to other sectors.
- Insetting is defined as company projects to reduce or remove emissions within their own internal supply chains. Proponents say it is valuable for agriculture-based firms struggling to address indirect emissions from land that has already been deforested. Like offsets, insetting can bring social and economic benefits to communities.
- Some oppose the tool outright, saying it is subject to the same problems as offsets (including lack of permanence and enforceable standards), but can also be worse as it can lead to double-counting climate benefits and can have weaker oversight.
- Having now become popular with major corporations such as Nestlé and PepsiCo, insetting as a climate tool is poised to see increased scrutiny as companies and researchers figure out its place in corporate action and reckon with the urgency to reduce emissions from agriculture.

Herders turn to fishing in the desert amid severe drought, putting pressure on fish population
- As Northern Kenya’s unabating drought continues, a growing wave of pastoralists are finding it challenging to keep their livestock alive and are switching to fishing in Lake Turkana, the world’s largest desert lake.
- However, environmentalists, fishing authorities, and some fishers worry that potential overfishing and increased pressures on fish populations will cause a collapse in fish stocks and the lake’s ecosystem.
- Authorities are also concerned about the rampant use of illegal fishing gear, such as thin mesh nets that catch undersized fish in shallow breeding zones, and an illegal tilapia smuggling network draining the lake by the tons.
- Though no studies have yet been done to assess fish populations, some environmentalists and fishers are calling for better enforcement of regulations to keep livelihoods afloat.

On Lombok, rising sea levels force fishers into different jobs
- Residents of the Indonesian island of Lombok say sea levels are rising at alarming levels, swallowing seaside towns.
- People are abandoning their family trade of fishing to instead grow seaweed or leave the island for stable employment.
- The provincial government created a climate adaptation task force to address the compounding problems of climate change, as families send their children to school and hope they choose a life different from fishing.

Pollution and climate change set stage for rise in antimicrobial resistance
- A new report from the United Nations Environment Programme illustrates the role that pollution, climate change and biodiversity loss can play in the development of antimicrobial resistance.
- The compounds used to treat bacterial, viral, parasitic and fungal infections have saved countless lives, but their overuse and their presence in the environment from human waste, agriculture and effluent from the pharmaceutical industry and places like hospitals has given rise to resistance to these chemicals in potentially harmful microbes.
- If this resistance continues to increase, experts warn that an additional 10 million people may lose their lives by 2050 — about the same number who died of cancer in 2020.
- The report’s authors recommend stronger safeguards around industrial runoff, better sanitation and more judicious use of antimicrobials to address this potential crisis.

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.

In Brazil’s agricultural heartland, rivers run dry as monoculture advances
- The Paraná River Basin has suffered an unprecedented drought since 2021, affecting hydropower generation, river-borne food shipments, and freshwater supplies for 40 million people across Brazil, Argentina and Paraguay.
- In Brazil, the prolonged drought has hit some of the region’s most important reserves, including Várzeas do Rio Ivinhema State Park, which houses one of the last slices of forest in Mato Grosso do Sul state and acts as a refuge for hundreds of species.
- The drought has drained lagoons in the park, made parts of the reserve more prone to wildfires, and disrupted the breeding cycles of native birds.
- Environmentalists blame the advance of large-scale monoculture in the region, which has cleared most of the forests and ushered in changes in rain patterns and droughts.

Breaking free from photosynthesis: Will high-tech foods save nature?
- Soaring industrial livestock production is dramatically increasing greenhouse gas emissions, deforestation and biodiversity loss. Current meat production methods are unsustainable and fast pushing the natural world and the global food system to the edge of collapse, argues British environmentalist George Monbiot.
- Monbiot says conventional solutions, like a global switch to veganism and/or the large-scale implementation of sustainable agroecology, are advancing too slowly to avert looming disaster. The only solutions, he says, are rapid high-tech fixes.
- The best approach, he contends, is one that would free food production from photosynthesis, using hydrogen drawn from water to feed protein- and fat-rich bacteria. The revolutionary technology can produce meat and cheese from the air that, reportedly, tastes as good as the “real” thing.
- Critical voices fear this not-yet-widely-tested techno fix may be a “magic bullet” that doesn’t work in the real world. Others say the only path to averting climate catastrophe is via mobilization around food sovereignty — the right of everyone to healthy foods produced by ecologically sound and sustainable methods, including innovations by traditional peoples.

With climate reparations finally on the table at COP27, what now?
- The question of who should pay damages for climate change-induced losses is finally on the table at the COP27 climate summit in Sharm el-Sheikh, Egypt.
- While mitigation and adaptation goals aim to curb carbon emissions and prepare for future impacts, loss and damage is concerned with harm already wrought by climatic disruptions or locked in by current emission levels — and with who should foot the bill.
- Emerging research on climate-related damages shows that the U.S. could face the biggest claims for reparations, even though drawing direct causal links between carbon emissions arising in one country and damaging climatic events in another country is complicated.
- “Is there a scientific basis for loss and damage and climate liability? The answer is yes,” says Justin Mankin, a climate scientist at Dartmouth College in the U.S. and co-author of a recent study on calculating climate damages.

Agroecology can feed Africa and tackle climate change — with enough funding
- Advocates say agroecological systems are the way to meet the climate crisis in its fullness — from limiting emissions to coping with climatic shocks — provided it gets the support of national governments and international donors.
- They are pushing for agroecology to be considered a climate solution by leaders at the COP27 climate summit in Egypt later this month.
- The agroecology movement is forged around opposition to the mindless transplantation of large-scale industrial agriculture to African countries, which is also one of the major sources of greenhouse gas emissions in more industrialized nations like the U.S.
- But its direct impacts on carbon budgets and effectiveness as an adaptation tool are understudied. Proponents like Bridget Mugambe say this hurdle could be overcome with adequate funding.

Pandemic dip was just a blip as global emissions rebound, report shows
- A recent report published by the Emissions Database for Global Atmospheric Research (EDGAR), a scientific group associated with the European Commission, found that while global CO2 emissions dropped in 2020, they returned to nearly pre-pandemic levels in 2021.
- The report found that China, the United States, the 27 countries that make up the European Union, India, Russia and Japan continue to be the world’s largest emitters, contributing about 70% of global CO2 emissions. Some of these countries’ emissions continued to rise, but others fell from 2019 levels.
- While experts say the EDGAR report provides a comprehensive view of global emissions, they point to limitations in the data, such as the fact that it only accounts for CO2 but not other greenhouse gas emissions.
- It’s estimated that the world has already warmed about 1.2°C (2.2°F) above pre-industrial levels, but some experts say we can still meet the target of the Paris Agreement targets if nations have the political will to instigate change.

‘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.

Seaweed an increasingly fragile lifeline for Philippine farmers
- Commercial seaweed farming began in the Philippines in the 1970s and has grown to be one of the country’s most significant aquaculture enterprises, supporting more than 200,000 coastal families.
- In communities in Palawan, seaweed farming also plays a role in protecting marine life, with small farmers serving as extra eyes and ears in the fight against illegal fishing.
- As climate change intensifies, warmer waters are making seaweed farms more susceptible to pests and diseases, threatening the survival of the industry and the families that depend on it.

Urban farming in Indonesia addresses food needs and climate crisis
- Grassroots initiatives in several Indonesian cities have sprung up aimed at achieving food security through urban and family farming.
- Proponents say this is a great way to diversify food variety and cushion the impact of rising food and commodity prices.
- They also tout its ecological benefits, including lower emissions and healthier soil than with commercial farming.

Bad weather knocks down Brazil’s grain production as ‘exhaustively forewarned’
- Brazil’s agricultural GDP declined by 8% in the first quarter of 2022 due to a severe drought in the country’s south caused by a rare triple-dip La Niña.
- In Rio Grande do Sul, the nation’s southernmost state, 56% of last year’s total soy harvest was lost, harming thousands of farmers.
- Scientists warn that climate change will make Brazil’s southern region, an agribusiness stronghold, widespread crop losses more common.
- Despite warnings, climate denial in the agriculture sector is getting in the way of mitigation efforts as the government of President Jair Bolsonaro and the agribusiness lobby push an anti-environmental agenda.

In Sumatra, rising seas and sinking land spell hard times for fishers
- Fishers operating near the port of Belawan on the Indonesian island of Sumatra are reporting declining catches and a hit to their livelihoods from tidal flooding.
- The flooding has grown more frequent and severe, exacerbated by rising seas and the clearing of mangrove forests for oil palm plantations.
- Traders who buy local catches have also been affected by the flooding, which can cut off commercial transport routes.
- This region of northern Sumatra is one of the areas targeted by the Indonesian government for mangrove restoration, but until that yields results, the fishers say they’re essentially helpless.

As stronger storms hit Bangladesh farmers, banks are climate collateral damage
- Farmers in coastal areas of Bangladesh are increasingly defaulting on their loans due to climate change-driven storms that are destroying the farms they put up as collateral.
- Agricultural loans for the year to May 2022 amounted to the equivalent of $3 billion, or a fifth of the value of all loans distributed in Bangladesh.
- Increasingly frequent and severe storms therefore pose as much of a threat to the country’s financial sector as to farming communities and the environment.
- The warming of the sea in the Bay of Bengal as a result of climate change is supercharging storms, giving them more energy, helping them to drive tidal surges farther inland and dump larger volumes of rain than before.

Climate change amplifies the risk of conflict, study from Africa shows
- New research shows that climate change can amplify the risk of conflict by as much as four to five times in a 550-kilometer (340-mile) radius, with rising temperatures and extreme rainfall acting as triggers.
- Many countries most vulnerable to climate impacts are beset by armed conflicts, such as Somalia, which is grappling with widespread drought amid a decades-long civil war; the research suggests the country is trapped in a vicious cycle of worsening climatic disasters and conflict.
- Both too little rain and too much rain are triggers for conflict, the research finds: persistent rainfall failures increase instability over a broader geographic region while extreme rainfall increases the likelihood of confrontations over a smaller area and for a shorter time, the analysis suggests.
- The research underscores the importance of tackling climate change impacts and conflict mitigation together because misguided climate adaptation strategies can intensify existing tensions.

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.

A tale of successes and new challenges in Senegal: Q&A with ICCA coordinator Salatou Sambou
- The Kawawana conserved area (ICCA) was created by a group of Indigenous Jola fishers in Casamance. After almost ten years, they have succeeded in restoring an area where biodiversity had all but disappeared.
- Now that biodiversity and resources have recovered, life in the village has become more secure. The model’s success has also encouraged young people to return and to renew their commitment to its conservation.
- But the ICCA has also come up against many challenges, such as the COVID-19 pandemic, state indifference to poachers and climate change, since Mongabay’s last reporting in 2018.
- Mongabay interviewed Salatou Sambou, ICCA coordinator involved in the Kawawana conserved area, about the recent successes and challenges the ICCA is facing.

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.

Podcast: Indigenous, ingenious and sustainable aquaculture from the distant past to today
- On today’s episode of the Mongabay Newscast we look at Indigenous peoples’ long relationship with, and stewardship of, marine environments through two stories of aquaculture practice and research.
- Nicola MacDonald joins us to discuss Kōhanga Kūtai, a project in New Zealand that aims to replace the plastic ropes used by mussel farmers with more sustainable alternatives. MacDonald discusses the project’s blending of traditional Maori knowledge with Western science.
- We also speak with Dana Lepofsky, a professor in the archaeology department at Simon Fraser University in British Columbia, Canada, who shares her research upon clam gardens along the Pacific coast of North America. Some of these clam gardens have been found to be at least 3,500 years old, and were such a reliable and sustainable source of food that there’s a movement afoot to rebuild them today.

In Sierra Leone, local fishers and foreign trawlers battle for their catch
- At wharfs across the Freetown peninsula in Sierra Leone, local fishers say in recent years it’s become harder to get a good catch. They blame foreign trawlers for overexploiting the country’s fish stocks.
- Sierra Leone’s Ministry of Fisheries and Marine Resources says it has systems meant to curb illegal, unreported, and unregulated fishing, but enforcement remains a challenge.
- In 2019, China signed a fisheries agreement with Sierra Leone that includes a promise to build a $55 million harbor, but some fishers say boats owned by its citizens are among the worst offenders.

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.

Partnering with farmers is key to land restoration success (commentary)
- The UN declared 2021–2030 to be the Decade on Ecosystem Restoration, but global initiatives aiming to tackle land degradation run the risk of failing unless they shift their approach to include farmers.
- Agricultural techniques that restore land such as agroforestry boost crop production and also positively contribute ‘ecosystem services’ such as fuelwood production, habitat creation, carbon sequestration and erosion control.
- We must acknowledge that local people have a wealth of knowledge about where they live, so tapping into this knowledge and gaining their partnership is key to long-term restoration goals, a new op-ed argues.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Cradle of transformation: The Mediterranean and climate change
- The Mediterranean region is warming 20% faster than the world as a whole, raising concerns about the impacts that climate change and other environmental upheaval will have on ecosystems, agriculture and the region’s 542 million people.
- Heat waves, drought, extreme weather and sea-level rise are among the impacts that the region can expect to see continue through the end of the century, and failing to stop emissions of carbon dioxide and other greenhouse gases could make these issues worse.
- Charting a course that both mitigates climate change and bolsters adaption to its effects is further complicated by the Mediterranean’s mix of countries, cultures and socioeconomics, leading to wide gaps in vulnerability in the region.

Indonesians, too reliant on palm oil, should go back to their roots (commentary)
- Scarce supplies and high prices for cooking oil have sparked recent widespread public criticism in Indonesia, the world’s top producer of palm oil.
- Yet before the introduction of the African oil palm into Indonesia, communities across the archipelago were producing the oil they needed from coconuts.
- Mongabay Indonesia’s Taufik Wijaya recalls this practice from his childhood in South Sumatra, when the Western-influenced diet of deep-fried food hadn’t yet taken hold.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

As the Horn of Africa heats up, the risks of insecurity are rising (commentary)
- World leaders are increasingly concerned about the complex connections between climate and insecurity, including the risk that climate disruption is a “conflict multiplier.”
- The threat is particularly acute in the Greater Horn of Africa, where populations already grappling with food insecurity and armed conflict are experiencing some of the fastest-warming conditions in the world.
- Noting that “the fortunes and stability of this region of 365 million people now look to be at the mercy of weather-driven mayhem”, Robert Muggah, Peter Schmidt, and Giovanna Kuele of the Igarapé Institute draw attention to various efforts already underway in the region to build resilience and call for stepped-up support from global powers.

World’s biggest tropical crop bank opens in Colombia, taking food research high tech
- Colombia has inaugurated the world’s largest repository for beans, cassava and tropical forages near the city of Cali.
- To withstand droughts, heat, floods and disease, crops need to be resilient, and that resiliency comes from genetic diversity.
- The Future Seeds facility will not only safeguard the biodiversity of important tropical crops, but is also expected to serve as a living laboratory for some of the most advanced technologies in agricultural research including a rover built by Google’s Project Mineral, and the use of artificial intelligence.

Banning high-deforestation palm oil has limited impact on saving forests: Study
- Import bans on palm oil produced through deforestation haven’t had as strong an effect in preventing forest loss as might be expected, according to a new study.
- The paper’s modeling looked at what impact restrictions in Europe on imports of high-deforestation palm oil from Indonesia would have had from 2000-2015.
- They found these restrictions would have reduced deforestation by just 1.6% per year, and emissions by 1.91% per year compared to what actually occurred.
- The study authors and other researchers say the findings underscore the point that demand-side restrictions are only one tool in addressing commodity-driven deforestation, and should be part of a wider suite of incentives and disincentives.

Bleached reefs still support nutritious fish, study finds
- A recent study published in the journal One Earth looked at the nutrients available in fisheries in Seychelles before and after bleaching killed around 90% of the island nation’s coral in 1998.
- Warming ocean temperatures have caused mass bleaching of corals across the tropics, sometimes causing the deaths of these reef-building animals, and the phenomenon is expected to continue as a result of climate change.
- The research found that bleached reefs continue to support fisheries that provide essential micronutrients to human communities.

By cultivating seaweed, Indigenous communities restore connection to the ocean
- In many places, Indigenous communities are working to restore seaweed species that have been traditional food sources or supported traditional diets.
- From kelp farms in Alaska to seaweed-focused community education in Hawai‘i, the projects take many forms.
- These Indigenous groups are reemphasizing the ability of marine algae and plants to support food sovereignty, climate resilience, and connections to tradition.

Warmer, oxygen-poor waters threaten world’s ‘most heavily exploited’ fish
- A new report using core samples taken from the seabed has determined that the Humboldt Current system off the coast of Peru was home to smaller fish during the last interglacial period, 130,000 years ago.
- The conditions back then — with little oxygen content in the ocean and temperatures about 2°C (3.6°F) warmer than the average temperature in the current Holocene epoch — mirror those that scientists have predicted for 2100.
- While many studies have argued that warmer water and lower oxygen lead to smaller fish, the added pressure of industrial fishing has made it difficult to determine the threat that climate change will pose on fisheries.
- The Humboldt Current system is one of the most productive fisheries in the world, contributing to more than 15% of the global annual fish catch, so significant changes to this system will threaten food security.

Indigenous food systems can provide game-changing solutions for humankind (commentary)
- Although strides have been made in agricultural systems to feed the world population, they have also led to increased emissions and biodiversity loss.
- Indigenous food systems, practiced over millennia, can provide solutions, as shown in a recent report whose findings have spurred scientists and a coalition of several countries to work together to preserve and strengthen Indigenous food systems.
- This article is the last of an eight-part series showcasing Indigenous food systems covered in the most comprehensive FAO report on the topic to date.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

As its topsoil washes away, the Corn Belt is losing yields — and carbon
- Scientists have found that the Corn Belt region of the U.S. Midwest, which produces 75% of U.S. corn, has lost around 35% of its most fertile topsoil since European colonization in the 1600s.
- This was the first study to use satellites and lidar to estimate the relationship between soil loss and the topography of the land, verified by on-the-ground soil samples. Hilltops were often completely denuded of topsoil and soil in low-lying areas was prone to erosion.
- When soil is lost, so is the carbon stored in the ground. Globally, more carbon is stored in the soil than in all the Earth’s plants and the atmosphere combined.
- Bringing soil back to the Corn Belt, experts say, will require a combination of regenerative agriculture and managing farms at the landscape level, planting in areas with high average yield and restoring other areas to pasture or using soil-building methods such as cover cropping.

Urban ecology that saved Argentina’s Rosario held up as a model for others
- The Argentine city of Rosario has over the past two decades developed private-public partnerships to set aside land for farming and create a network of local markets where farmers locally sell their crops.
- Local sustainable farming is seen as a solution to mitigate climate change and promote biodiversity, and Rosario’s urban agriculture program does this by growing food for domestic consumption.
- This reduces greenhouse gas emissions from food transportation, boosts the amount of green space within the city to reduce the urban heat island effect, and allows diverse wildlife populations to thrive alongside crops.
- Rosario’s detailed maps identified vacant land unsuitable for other purposes and reimagined that land to create farms within the city, while collaboration with neighboring jurisdictions has led to the development of an agricultural green belt surrounding Rosario.

Mali’s centuries-old pastoralist traditions wilt as the climate changes
- As the world rediscovers the ingenuity of nature-based solutions, a detailed FAO report published this year highlights the traditions of nomadic pastoralists in Mali who have sustained an eco-friendly lifestyle over centuries.
- The Kel Tamasheq people, living amid the Saharan sands near Timbuktu, eat primarily local produce, generate little waste, and boast a negligible carbon footprint.
- The community’s world revolves around a transhumance tradition that follows seasonal movement; during the dry season, which lasts for more than six months of the year, the pastoralists migrate south with their livestock in search of grazing land and water.
- Climate change and increasing desertification have heavily impacted the food system of the Kel Tamasheq, especially the withering of Lake Faguibine, intensifying the community’s dependence on markets.

Small coffee farmers lay their chips on smart agriculture to overcome climate crisis in the Cerrado biome
- A long drought followed by a strong freeze in 2020 damaged the coffee harvest in Brazil, the world’s biggest producer and exporter of the crop.
- Small farmers in the Cerrado region who generally don’t use irrigation because of the area’s historically abundant rainfall were hit the hardest.
- To take on the challenges brought on by the changing climate, coffee farmers in the Cerrado have joined a climate-smart agriculture program.
- The strategies adopted for more resilient crops include agroforestry, connected landscapes, and water resource management.

As climate-driven drought slams farms in U.S. West, water solutions loom
- Drought in the U.S. West has been deepening for two decades, with no end in sight. Unfortunately for farmers, water use policies established in the early 20th century (a time of more plentiful rainfall), have left regulators struggling with their hands tied as they confront climate change challenges — especially intensifying drought.
- However, there is hope, as officials, communities and farmers strive to find innovative ways to save and more fairly share water. In Kansas and California, for example, new legislation has been passed to stave off dangerous groundwater declines threatening these states’ vital agricultural economies.
- Experts say that while an overhaul of the water allocation system in the West is needed, along with a coherent national water policy, extreme measures could be disruptive. But there are opportunities to realize incremental solutions now. Key among them is bridging a gap between federal water programs and farmers.
- A major concern is the trend toward single crop industrial agribusiness in semi-arid regions and the growing of water-intensive crops for export, such as corn and rice, which severely depletes groundwater. Ultimately, 20th century U.S. farm policies will need to yield to flexible 21st century policies that deal with unfolding climate change.

Climate change agricultural impacts to heighten inequality: Study
- Major changes in crop productivity will be felt globally in the next 10 years according to new computer simulations. Climate impacts on crops could emerge a decade sooner than previously expected in major breadbasket regions in North America, Europe and Asia according to the new forecasts.
- Researchers combined five new climate models with 12 crop models, creating the largest, most accurate set of yield simulations to date. Corn could see yield declines of up to 24% by 2100, while wheat may see a boost to productivity. In some sub-tropical regions, climate impacts on crops are already being felt.
- High- and low-emissions scenarios project similar trends for the next 10 years, suggesting these agricultural impacts are locked-in. But actions taken now to mitigate climate change and alter the long-term climate trajectory could limit corn yield losses to just 6% by 2100.
- Climate adaptation measures such as sowing crops earlier or switching to heat- tolerant cultivars are relatively cheap and simple to implement, while other actions, such as installing new irrigation systems, require financial investment, planning, and time.

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.

An Indigenous community in India’s Meghalaya state offers lessons in climate resilience
- The Indigenous food system of the Khasi community in Nongtraw village in Meghalaya offers lessons in climate resilience and sustainable food systems, says a United Nations Food and Agricultural Organisation report.
- The traditional food production system is supported by jhum (shifting cultivation), home gardens, forest and water bodies and shies away from the use of synthetic chemicals. It is based on community-led landscape management practices, regulated by local governance.
- Factors such as the emergence of cash crop production (broom grass), the impact of India’s public distribution system on the local subsistence system and over-reliance on market-based products are weakening the food system’s resilience.
- Research priorities on Indigenous food systems should include systematic documentation of a wide variety of Indigenous foods known to the Indigenous communities, their contribution to food security and dietary diversity.

Between land and sea: Agrobiodiversity holds key to health for Melanesian tribes
- Residents of Baniata village on the Solomon Islands’ Western province practice an ancient agroforestry system that intercrops 20 edible species and features the ngali nut, a delicacy sold in domestic and international markets.
- The community’s traditionally self-sufficient and biodiverse diet features 132 species, notably the fe’i banana, a Melanesian specialty that contains 100 times the vitamin A of a typical banana.
- The resilient food system and diet is increasingly affected by climate change, imported crops, processed foods, and the loss of traditional knowledge in younger generations.
- This article is one of an eight-part series showcasing Indigenous food systems covered in the most comprehensive FAO report on the topic to date.

Climate change means hunger in our communities, African women leaders at COP26
- Activists and delegates from developing countries, including many African nations, have strained but so far failed to define the debate at COP26 as one of climate justice. They emphasize that developed nations have largely caused the climate crisis, while developing nations often suffer the worst consequences.
- In 2015 when countries signed the Paris climate agreement, the per capita emissions of Madagascar, which is facing the world’s first climate change-induced famine, stood at 0.12 tons/person, compared to 16 tons/person for the United States.
- At a COP session organized by the British philanthropy Campaign for Female Education (CEMFED) this week, delegates from countries in Sub-Saharan Africa underlined the link between climate change and hunger.
- The climate talks have come under scrutiny for poor representation from African nations, some of the most vulnerable to climate impacts.

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.

In Peruvian Andes, ancient crops hold promise for a climate-blighted future
- The government of Peru has declared Marcapata Ccollana a new agrobiodiversity zone in the Andean highlands.
- The reserve is home to an Indigenous community that preserves Incan farming techniques and grows more than 100 varieties of root vegetables in addition to many kinds of beans, maize and grains.
- Agricultural biodiversity is an essential resource for adapting global food supplies to the challenges posed by climate change.

Children born in 2020 will see spike in climate disasters, study says
- The study used climate modeling to determine specialized impacts by region, finding that at the current level of carbon reduction pledges, people born in 2020 will experience many more extreme climate events in comparison to those born in 1960.
- On the world’s current course, those children will experience twice as many wildfires overall, three times as many crop failures, and seven times as many heat waves.
- At a geographical scale, children born in low-income countries that are least responsible for the climate crisis will confront significantly higher spikes in extreme events than in wealthier countries.
- If the world takes a more aggressive approach to limiting warming to 1.5°C (2.7°F) by 2100, the number of climate disasters experienced by younger generations would drop substantially, with the model predicting 45% fewer heat waves, 39% fewer droughts, and 28% fewer crop failures.

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.

Amazon, meet Amazon: Tech giant rolls out rainforest carbon offset project
- Tech giant Amazon has announced a nature-based carbon removal project in the Brazilian Amazon Rainforest in partnership with The Nature Conservancy (TNC).
- The project will help small farmers produce sustainable agricultural produce through reforestation and regenerative agroforestry programs, in exchange for carbon credits that will go to the internet company.
- Called the Agroforestry and Restoration Accelerator, the initiative is expected to support 3,000 small farmers in Pará state and restore an area the size of Seattle in the first three years, and in the process remove up to 10 million metric tons of carbon dioxide from the atmosphere through 2050.
- In addition to addressing climate and social issues, the partners say the project intends to address the shortcomings of the carbon credit market by creating new standards for the industry.

In Peru, ancient food technologies revived in pursuit of future security
- Surrounded by mountains and eagles, a man from a highland community in Peru has built a stone and mud qolca, a food storage silo inspired by ancestral technologies.
- In his community, as in the rest of the Andes, increasingly erratic rainfall patterns and unexpected frosts and pest plagues threaten the rich local biodiversity and their generous harvests.
- Almost 500 years after the construction of the last qolca in the Cusco Valley, this new effort is a bid for a tomorrow without hunger in these times of pandemic and climate crisis.

Scientists look to wheatgrass to save dryland farming and capture carbon
- Intermediate wheatgrass is an imported grain that has been grown in the U.S. Great Plains and Intermountain West since the 1930s; but could it be used in marginal fields in dryland areas?
- Kernza, an intermediate wheatgrass bred by the Land Institute, is being planted in eastern Wyoming, where researchers from the University of Wyoming are uncovering whether the crop can help farmers stabilize and bolster their soils, while providing a profitable crop.
- Planting perennial crops, like Kernza, can help soil health and stability, retain moisture, and cut down on planting costs and greenhouse gas emissions from annual plantings.

Mexico devises revolutionary method to reverse semiarid land degradation
- Land degradation is impacting farmlands worldwide, affecting almost 40% of the world’s population. Reversing that process and restoring these croplands and pastures to full productivity is a huge challenge facing humanity — especially as climate change-induced drought takes greater hold on arid and semiarid lands.
- In Mexico, a university-educated, small-scale peasant farmer came up with an innovative solution that not only restores degraded land to productivity, but also greatly enhances soil carbon storage, provides a valuable new crop, and even offers a hopeful diet for diabetics.
- The process utilizes two plants commonly found on Mexico’s semiarid lands that grow well under drought conditions: agave and mesquite. The two are intercropped and then the agave is fermented and mixed with the mesquite to produce an excellent, inexpensive, and very marketable fodder for grazing animals.
- The new technique is achieving success in Mexico and could be applied to global degraded lands. Experts with World Agroforestry warn, though, that agave and mesquite are highly invasive outside their region, but suggest that similar botanical pairings of native species are potentially possible elsewhere.

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.

Humans’ role in climate warming ‘unequivocal,’ IPCC report shows
- The greenhouse gases humans have released into the atmosphere over the past 100 to 150 years has led to a 1.1°C (2°F) rise in global temperatures, according to the Intergovernmental Panel on Climate Change, or IPCC.
- The authors of the IPCC’s latest report use the strongest language yet to connect human activity to climate change, calling the link “unequivocal.”
- The report draws on the findings of thousands of studies, pointing to the need to cut CO2 emissions immediately while also suggesting that many of the impacts of climate change are irreversible.
- This report focuses on the science behind climate change and will be combined with two subsequent reports on the adaptation and vulnerability to the impacts of climate change and ways to mitigate its effects to produce the IPCC’s sixth assessment, scheduled for publication in September 2022.

A world of hurt: 2021 climate disasters raise alarm over food security
- Human-driven climate change is fueling weather extremes — from record drought to massive floods — that are hammering key agricultural regions around the world.
- From the grain heartland of Argentina to the tomato belt of California to the pork hub of China, extreme weather events have driven down output and driven up global commodity prices.
- Shortages of water and food have, in turn, prompted political and social strife in 2021, including food protests in Iran and hunger in Madagascar, and threaten to bring escalating misery, civil unrest and war in coming years.
- Experts warn the problem will only intensify, even in regions currently unaffected by, or thriving from the high prices caused by scarcity. Global transformational change is urgently needed in agricultural production and consumption patterns, say experts.

Old and new solutions pave way to net-zero emissions farming, studies show
- Agriculture and food account for one-third of global greenhouse gas emissions, making these sectors critical in efforts to address our current overshoot of the climate planetary boundary. They are also having profound impacts on freshwater, biodiversity and biogeochemical cycles.
- New and emerging technologies could pave the way to net-zero emissions agriculture in the next two decades, using robotics, electric vehicles, improved crop varieties and distributed monitoring, according to a new study. Precision agriculture could cut emissions by 71% and help build soil carbon stores.
- A second study reports that microbial protein cultivation powered by solar panels could achieve up to 10 times higher protein yield per unit of land than staple crops like soybeans, reducing greenhouse gas emissions from land conversion and synthetic fertilizers.
- A third report shows that Europe could feed a projected population of 600 million by 2050 with organic farming alone, by reducing consumption of animal products to around 30% of our diet, implementing crop rotations, and reconnecting livestock and cropping systems via use of manure.

Study puts 2050 deadline on tipping point for Mekong Delta salinity
- The increasing salinity in Mekong Delta is currently being driven by the building of dams upstream and sand mining downstream, but climate change will likely be the predominant factor by 2050, a new study shows.
- The Mekong Delta is a key farming region, and already more frequent and extensive saltwater intrusion is killing off large swaths of crops with greater frequency.
- The study’s authors say regional stakeholders need to address the anthropogenic drivers of saltwater intrusion in the delta now, before climate change makes it a global problem.
- The study also has implications for other delta systems across Asia, which face similar pressures, both anthropogenic and climate change-driven.

Biofuel in Mexico: Uphill battle against bureaucracy, organized crime
- Biofuels based on pressed plant oils, and made especially from used cooking oil, could help Mexico’s public transport sector transition to a cleaner and climate-friendly energy era, according to researchers and industry entrepreneurs.
- But there is a lack of government regulatory support, while the nation’s new president is betting on fossil fuels and neglecting biodiesel options and nature-based climate solutions.
- As a result, small biodiesel producers have to operate in a legal gray zone, while industry entrepreneurs are held back in the development of the technology and the market.
- Mexico isn’t alone: Many nations large and small are struggling with hurdles imposed by fossil fuel-friendly governments and a lack of supportive regulations to create a level playing field for the rapid development and deployment of biodiesel and other climate-friendly alternative energy solutions.

Converting biowaste to biogas could power cleaner, sustainable Earth future
- Biogas made from organic materials — including food and agricultural waste, and animal or human manure — is a renewable, sustainable, affordable and inclusive energy alternative becoming increasingly available to households, farms, municipalities and nations.
- Converting biowaste into biogas, via anaerobic digestion technology, is a strategy that could contribute to multiple U.N. Sustainable Development Goals and the Paris climate agreement. Biodigesters are already in use to meet a range of energy needs around the world.
- Current limiting factors to the sector’s growth include technical and adaptive challenges, lack of awareness in many regions, and unsupportive policy instruments that can discourage biogas adoption.
- Ahead of COP26, the critically important U.N. climate meeting coming this November, the World Biogas Association is urging governments to integrate biogas into their Nationally Determined Contributions — their voluntary emissions reduction targets, as agreed to under the Paris Agreement.

Cleaning up Cambodia’s kitchens could curb deforestation, climate change
- NGOs and companies across Cambodia are taking action in response to the mass use of charcoal and forest biomass in household and restaurant kitchens countrywide. The shift away from these polluting fuel sources to cleaner energy alternatives is being sparked by health and environmental concerns.
- Education is a key strategy for implementing the shift away from charcoal and wood, as their use is ingrained in the culture, with many Cambodians saying food doesn’t taste as good when cooked with other fuels.
- One innovative solution is turning the country’s coconut husks into “green charcoal,” which is already earning the nation recognition for being a global leader within the sustainable charcoal sector.
- Cambodia’s farmers are also moving away from using forest biomass for energy, and are instead utilizing biodigesters to turn household and farm waste into biogas for cooking and to make organic fertilizer.

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.

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.

Industrial diets are imprinting on human bodies, new study finds
- A new analysis shows that eating mass-produced food grown with the help of synthetic fertilizers, sourced internationally, is changing the chemistry of modern humans.
- It is especially true for urbanized and wealthier communities and nations where annual per capita income exceeds $10,000, where supermarkets supply most of the food.
- The isotope composition of nitrogen and carbon present in hair, nails and bones has changed, making present-day humans more similar to each other but very different from their ancestors who lived before the advent of industrial agriculture.
- The problem with these kinds of diets divorced from natural complex food chains is that the system is not resilient in the face of threats, study authors said.

Food systems drive a third of greenhouse gas emissions, study estimates
- A new study provides a comprehensive look at how food systems — from the growing of food to its distribution to its consumption and even its disposal — contribute to global greenhouse gas emissions.
- It suggests that food systems are responsible for a third of all human-made greenhouse gas emissions, reinforcing previous research that provided similar estimates.
- According to one expert, the dietary habits of people in developed nations can largely determine the greenhouse gas emissions in low-income countries, although the study does not explicitly state this.
- Experts say that reform is needed to make food systems more sustainable, and to function within the Earth’s planetary boundaries.

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.

Developing nations pay for rich countries’ hunger for healthy, exotic food
- A new study shows that high-income countries place enormous demands on developing countries’ by importing crops that rely heavily on pollinators.
- The researchers apply the principle of Virtual Water, where goods are seen not just as movements of things but also of raw materials and services, in this case of pollinators.
- A growing demand in places like the U.S. and Europe for healthier diets, rich in fruits and beans, is also putting pressure on scarce pollination services.
- Pollination services may be free, but there are hidden costs to maintaining them, and it is communities in developing countries who pay them, the study suggests.

Podcast: Can agroecology feed the world?
- Agroecology is an approach to sustainable farming that is quickly spreading around the globe, transforming the way food is produced.
- We’re joined on this episode of the Mongabay Newscast by food systems expert Anna Lappé who discusses why the idea that agroecology is a “low yield” practice is a myth, and just how important the growing adoption of agroecological practices around the globe is to the future of life on Earth.
- We’re also joined by behavioral scientist Philipe Bujold of the NGO Rare’s Center for Behavior & the Environment, who tells us about the organization’s Lands for Life program, which employs behavioral science to encourage smallholder farmers in Colombia to adopt more sustainable, climate-friendly farming practices.

Dusty winds exacerbate looming famine in Madagascar’s deep south
- At least 1.27 million people need humanitarian assistance in Madagascar’s drought-hit deep south, according to a Jan. 18 request by the U.N. and the Malagasy government for $75.9 million in international aid to cope with the crisis.
- The area is also experiencing dust and sand storms, a natural phenomenon known as a tiomena that is exacerbating the crisis by smothering crops, forests, buildings and roads.
- Tiomenas may be increasingly common as southern Madagascar undergoes a long-term drying trend.
- Experts say upgrading the area’s water supply system is an urgent priority and recommend massive tree planting to provide wind breaks, protect soils from erosion and create more humidity.

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.

In Madagascar’s hungry south, drought pushes more than 1 million to brink of famine
- In Madagascar’s deep south, 1.35 million people, including 100,000 children, could fall victim to malnutrition this year, as the worst drought in a decade grips the region.
- This remote region has witnessed 16 famines since 1896, eight of which occurred in the past four decades. Most were the direct result of rainfall deficits, but misguided or failed policies have deepened the distress.
- This year, with crop failures, pandemic-related restrictions curbing access to markets, and sharp increases in prices of essentials, food has remained out of reach for thousands.
- Such droughts and the attendant famines are likely to become more frequent due to climate change, producing more hunger and distress in one of the poorest countries in the world.

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.

Could disruptions in meat supply relieve pressure on the Amazon? (commentary)
- Ranching and beef production have put great pressure on the Brazilian Amazon, resulting in significant deforestation which harms biodiversity, could add to the destabilization of the global climate, and even lead to future pandemics. While much Brazilian meat is consumed domestically, a large portion is exported to China.
- With the pandemic raging out of control in Brazil, meat plants have become viral “hot spots” and helped to spread COVID-19 in several places around the country. Meanwhile, the global pandemic has, for a variety of reasons, now reduced meat consumption in both Brazil and China.
- Meat and dairy are responsible for public health problems and for 18% of global greenhouse emissions, so any reduction in consumption could be good for the health of the planet. Though the pandemic has led to untold human suffering, could cratering demand for meat lead to a new environmental consciousness?
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

A Philippine stingless bee helps boost coconut yields and empower women
- Tetragonula biroi, a stingless bee native to the Philippines, is being cultivated on a farm to both produce honey and pollinate coconut trees.
- The farm, owned by Luz-Gamba Catindig and employing local women, has seen an increase of up to 50% in its coconut yields; researchers say the presence of these pollinators, known as kiwot bees, can boost yields by up to 80%.
- Key to these improvements in productivity are upgrades to the common beehive, developed by local bee experts working with university researchers.
- Although kiwot bees produce less honey than the more common western honey bee (Apis mellifera), they produce more propolis, a resin-like substance with high medicinal and therapeutic potential.

In Sri Lanka, crop-destroying insects follow the COVID-19 pandemic
- In May, Sri Lanka recorded a sporadic increase in crop-damaging yellow-spotted grasshoppers (Aularches miliaris), leading to concerns that a pest outbreak could impact food security.
- Sri Lankan experts are also watching as harmful desert locusts (Schistocerca gregaria) damage crops in neighboring India and Pakistan, though it seems unlikely these locusts will arrive in the island nation.
- The decline of natural predators and recent changes in the climate may be helping to increase the frequency of these potentially devastating insect invasions.
- Experts have used drones to map and verify crop damage caused by grasshoppers.

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.

How coffee growers can adapt to a precipitous industry: Q&A with Dean’s Beans founder Dean Cycon
- Climate change is making traditional coffee-growing areas in the tropics less suitable for the crop, forcing farmers to look for new land at higher elevations and higher latitudes.
- Scientists are trying to tackle the problem by developing climate-resistant coffee plants, but solutions already exist from arid regions in Africa that can be adapted by farmers in Latin America.
- “This is something the scientific community is completely ignoring,” says Dean Cycon, founder of Dean’s Beans Organic Coffee and a longtime advocate of social justice for the millions of coffee farmers in the global south.
- In an interview with Mongabay, Cycon offers his unique insights into one of the world’s favorite beverages, the challenges of climate change, the plight of tropical farmers, and the solutions he sees as still within reach.

For Philippine farmers reeling from disasters, lockdown is another pain point
- Farmers in the Bicol region in the Philippines are experiencing the brunt of the lockdown, imposed since March 16 to contain the COVID-19 pandemic.
- The situation is especially hard for rice farmers, most of them still reeling from the impacts of successive typhoons, drought, and cheap imported rice.
- The Philippine government has allotted a 1.17 trillion peso ($23.2 billion) stimulus package, including support for some 18 million families most affected by the lockdown. In Bicol, more than one million families are expected to receive support.
- The Philippine lockdown is expected to lift by May 15, although the government says the country may have to continue dealing with COVID-19 for the new two years.

Climate fix? ‘Fertilizing’ oceans with iron unlikely to sequester more carbon
- Since the 1980s, scientists have studied whether adding iron to the oceans might represent a relatively simple and inexpensive solution to climate change.
- The idea is that adding iron would encourage the growth of carbon-munching marine phytoplankton that would pull carbon out of the atmosphere on a global scale.
- But a new study by researchers at the Massachusetts Institute of Technology suggests that iron fertilization, as the process is called, is unlikely to work.

Managing fisheries helps stocks recover — most of the time
- A recent study, representing 49% of the fish landed between 1990 and 2016, reveals that, on average, fish stocks are healthy where intensive fisheries management is implemented.
- The research demonstrates that managing fish populations with robust scientific data has helped turn the tide against overfishing in places around the world where it is practiced.
- But disagreements between scientists exist over whether other strategies, such as marine protected areas, should complement fisheries management in an effort to protect life in the world’s oceans.

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.

Modern farms need both high- and low-tech farming practices (commentary)
- Farmers across Argentina have had to contend with new and unprecedented pressures. As a third-generation Argentinian farmer, I have seen this first-hand.
- The key to surviving any major change is to adapt, and by embracing both low-tech and high-tech practices, farmers can thrive and prosper even in the face of significant climate and food security challenges.
- The use of biotech seeds, especially, provides farmers with much more flexibility in combating weeds and pests, without having to resort to mechanical production that breaks up the soil. Many countries have been slow, or perhaps reluctant, to adopt this kinds of technology. Yet Argentinian farms have reaped the benefits and are now able to make progress towards more sustainable agriculture.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Study examines how the Atlantic surfclam is successfully adapting to climate change
- Global climate change poses a severe threat to marine life, but scientists have found at least one species that appears to be successfully adapting to warmer ocean waters.
- A recent study published in the Proceedings of the National Academy of Sciences found that, even without factoring in the impacts of fishing, global animal biomass in Earth’s oceans is expected to decrease by as much as 17 percent by 2100 under a “high emissions” scenario that leads to 3-4 degrees Celsius of warming.
- However, a new study published in the journal Marine Ecology Progress Series, shows that, as ocean temperatures rise, Atlantic surfclams, a large saltwater clam found mostly in the western Atlantic Ocean, are capably shifting their range into waters that would have previously been inhospitable to their survival.

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.

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.

Ocean acidification could impact Atlantic cod populations more severely than previously thought
- A 2016 study determined that, at the ocean acidification levels expected by the end of the century if we do nothing to draw down CO2 emissions, twice as many cod larvae will die within their first 25 days, causing the number of cod who reach maturity and reproduce to drop by 8 and 24 percent for the Western Baltic and Barents Sea populations, respectively.
- Scientists hoped that those cod who managed to reach maturity might be helping the species adapt to the conditions brought on by global climate change. But new research appears to have dashed those hopes.
- The new study, which was published in the journal Global Change Biology last month, found that surviving cod larvae suffer significant organ damage and developmental delays that could cause problems throughout their lifetimes.

Our brains can lead us astray when making ‘eco-friendly’ decisions
- Humans rely on a set of cognitive tools, developed to help us sustain interpersonal relationships, to govern our choices that affect the global climate, a pair of psychologists suggests.
- People who purchase food with “eco-friendly” labeling might be apt to buy more of it thinking of it as an offset, when, in reality, all consumption has a climate cost.
- The team suggests that more accurate labeling could help consumers understand which choices are “less bad” rather than “good” for the environment.

Warmer waters shrink krill habitat around Antarctica
- A new study has found that fewer young krill are surviving to adulthood around Antarctica as ocean temperatures have risen in the Southern Ocean in the past few decades.
- The researchers, who looked at decades of data on krill body lengths and abundance, found that the highest densities of krill had shifted southward by some 440 kilometers (273 miles) since the 1920s.
- The scientists note that the findings could alter food webs in the Southern Ocean.
- Currently, the internationally managed krill fishery does not take the location and size of the krill population into account.

Policymakers are not adequately factoring land use and human diets into climate mitigation strategies: Study
- A recent study finds that governments and researchers routinely underestimate the potential for changes to land use and human diets to reduce greenhouse gas emissions and mitigate the impacts of global warming.
- Published in Nature last month, the research suggests that policymakers are not adequately accounting for the amount of carbon that could be stored in forests and other natural vegetation if those lands weren’t used for producing food, and are also failing to recognize the carbon emissions that will result from increased agricultural production.
- According to the study’s lead author, Tim Searchinger, a research scholar at Princeton University and a senior fellow at the World Resources Institute, these oversights on the part of climate policymakers are particularly crucial because successfully mitigating climate change will require more carbon be stored in forests and other native vegetation, even while the world will have to produce as much as 50 percent more food every year in order to feed the growing global population.

As climate change takes its toll, world leaders call for adaptation
- A new global initiative led by former U.N. secretary-general Ban Ki-moon aims to help the world adapt to the fallout from a changing climate.
- The Global Commission on Adaptation differs from current climate initiatives, which focus largely on mitigation, i.e. efforts to slow the emissions of greenhouse gases.
- The launch of the commission comes in the shadow of a new U.N. report warning of dire consequences from climate change affecting hundreds of millions of people around the world unless the global temperature rise is kept below 1.5 degrees Celsius (2.7 degrees Fahrenheit).
- But even if this is achieved, Ban says, irreversible changes have been made that are already manifesting as unseasonal heat waves, more destructive storms, and other extreme weather events — which will require adaptation rather than mitigation by countries worldwide.

Land rights, forests, food systems central to limiting global warming: report
- In the wake of the dire, just released UN Intergovernmental Panel on Climate Change report, a climate advocacy group known as CLARA (Climate, Land, Ambition and Rights Alliance) has published a separate report proposing that the world’s nations put far more effort into land sector measures to store carbon and reduce greenhouse gas emissions.
- They suggest that these nature-oriented, land-based approaches could be far more effective, and more rapidly implemented, than relying on costly or largely untested high tech solutions such as bioenergy, carbon capture-and-storage, and geoengineering.
- Among the approaches CLARA proposes are the establishment of far stronger land rights for indigenous peoples (who are among the world’s best forest stewards), as well as a serious reduction in deforestation and the restoration of forest ecosystems worldwide.
- The CLARA report also calls for the transformation of agriculture (less tilling, less fertilizers, more support for small farms), and a global revolution in dietary habits, including a reduction in meat consumption and less food waste.

Crop losses to insects will accelerate as the globe warms: study
- Insects already eat between 5 and 20 percent of the most important grain crops produced around the world — and new research finds that they could be responsible for even more crop damage in the near future as global temperatures continue to rise.
- Insect-driven losses of wheat, rice, and maize — the three major grain crops, which together provide more than 40 percent of calories consumed by humans worldwide — will increase 10 to 25 percent for every degree Celsius the average surface temperature of planet Earth rises, according to a study published in Science late last month.
- While bug populations may actually decline in some tropical areas, major grain-producing regions in northern climates are projected to be among the hardest-hit.

Ecology monks in Thailand seek to end environmental suffering
- At a time when Pope Francis is calling upon religious leaders to step up as environmental advocates, Thai Buddhist monks are answering the call. Through rituals like tree ordinations, monks are integrating Buddhist principles into the environmental movement in order to garner support from their followers and encourage sustainable practices.
- Although Buddhism is typically a religion famed for its detachment from society, ecology monks believe that their religion is inherently tied to nature.
- With such an immense amount of influence in villages throughout Thailand, Buddhist monks are utilizing their position to add a unique moral dimension to the environmental movement. However, rituals alone are not enough.

New research proposes solutions for reducing environmental costs of feeding Earth’s 7.6-billion human population
- Researchers at Oxford University in the UK and Agroscope, a Swiss agricultural research institute, have compiled an extensive database on food production around the world in order to determine the best means of reducing the environmental impacts of what we eat.
- To pinpoint possible solutions for reducing the impact of food production on terrestrial and aquatic ecosystems and the global climate that would be effective for the large and diverse range of food producers across the globe, the researchers compiled a database covering five different indicators of the environmental impacts of 38,700 farms and 1,600 processors, packaging types, and retailers.
- They found that environmental impacts can vary widely — by as much as 50-fold — even among producers of the same food product. These discrepancies in the environmental tolls exacted by the same foods when grown in different geographies and under different production practices present a number of opportunities to mitigate those impacts.

Rwandan people and mountain gorillas face changing climate together
- The Critically Endangered mountain gorilla (Gorilla beringei beringei), has been brought back from extinction’s brink in Rwanda, with numbers in the Virunga Mountains around Volcanoes National Park estimated at 604 individuals in 2016, up from 480 in 2010. But long-time observers say climate change is bringing new survival challenges to the area.
- Longer and deeper droughts in recent years have caused serious water shortages, which impact both local farmers and the mountain gorillas. People now must often go deep into the park to find clean water, which increases the likelihood of contact with the great apes, which increases the likelihood for the transfer of human diseases to the animals.
- Hotter temps and dryer conditions could also pressure farmers to move into gorilla habitat in future, as they seek more productive cropland at higher altitudes. Also, as the climate changes, bamboo availability may be decreasing, depriving gorillas of a favorite food. This could force troops to forage outside the park in croplands, possibly leading to conflict.
- Forced changes in diet could impact gorilla nutrition, making the great apes more susceptible to disease. A major disease outbreak could be disastrous due to low population numbers. Scientists urge more research to understand how climate change affects human behavior, which then affects gorillas, and how the fate of the two primates intertwines.

Beyond polar bears: Arctic animals share in vulnerable climate future
- The media has long focused on the impacts of climate change on polar bears. But with Arctic temperatures rising fast (this winter saw the warmest October to February temperatures ever recorded), a wide range of Arctic fauna appears to be at risk, though more studies are needed to determine precise causes, current effects on population, and future projections.
- Diminishing Arctic snow, especially in the spring, may leave wolverines without ideal places to den. Caribou and reindeer populations have been in serious decline due to natural population fluctuation, but scientists don’t know if their numbers will recover under changed climate conditions.
- Lemmings are also being impacted by diminishing snow, often leaving the rodents without cover in spring and autumn. Their decline could impact the predators that prey on them, including Arctic foxes, red foxes, weasels, wolverines, and snowy and short-eared owls.
- Snowy owls have raised concerns because the seabirds they hunt in winter, which congregate around small holes in the Arctic ice, could become more widely dispersed in broader stretches of open water and therefore be harder to prey on. Scientists say more study of Arctic wildlife is urgently needed, but funding and media attention remains sparse.

New study: Radar reveals bats are a bellwether of climate change
- New research indicates that bats could signal seasonal shifts due to climate change.
- The study, published in the journal Global Change Biology, is the first to use radar to track an animal migration.
- The scientists found that bats that migrate between Mexico and a cave in Texas are now arriving about two weeks earlier than they did in 1995.

‘Adaptation Bangladesh: Sea Level Rise’ film shows how farmers are fighting climate change
- A recent documentary looks at how Bangladeshi farmers are adapting to rising sea levels.
- The film documents how Bangladeshi farmers are keeping their farms from flooding by building floating gardens made of water hyacinth and bamboo.
- The film won the Best Short Film at the New York WILD Film Festival, which begins on Feb. 22.
- Mongabay interviewed cultural anthropologist Alizé Carrère to learn more about why she chose to focus on Bangladesh and why this story is important.

Consensus grows: climate-smart agriculture key to Paris Agreement goals
- Attendees at the annual Global Landscape Forum conference in Bonn, Germany, this week sought approaches for implementing “climate-smart” agricultural practices to help keep global temperature from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) by 2100.
- Some 40 percent of the earth’s surface is used for food production, with 400 million small farmers worldwide, plus industrial agribusiness, so policymakers understand that climate-smart agriculture, practiced broadly, could play a significant role in reducing carbon emissions and helping nations meet their Paris carbon-reduction pledges.
- Numerous agricultural management practices to reduce carbon emissions, enhance food security, productivity and profitability, are available now. They include wider use of cover crops, low and no till techniques, increased application of organic fertilizers such as manure, judicious use of chemical fertilizers, and the growing of crops bred for climate resiliency.
- These techniques are already being embraced to a degree in the U.S. and globally. Land of Lakes and Kellogg’s, for example, are insisting on sustainable farm practices from their suppliers, while John Deere is building low-till equipment that allows for “precision farming,” optimizing returns on inputs while preserving soils and soil carbon.

Global climate change increasing risk of crop yield losses and food insecurity in the tropical Andes
- Findings published last month in the journal Global Change Biology portend a difficult path to rural agricultural adaptation in the tropical Andes and drastically reduced crop yields at a time of growing populations and food insecurity.
- Researchers found that, with a temperature increase as small as 1.3 degrees C to 2.6 degrees C, nearly all corn plants died when grown at the same elevations as previous years and generations — either eaten by birds or ridden with pests.
- When the same crop was grown at a higher elevation in order to stay within its temperature comfort zone, the changing soils had an impact. Plants survived with fewer pests, but the crop yield and corn quality was reduced and thus the market value was diminished.

Lemur species losing favorite food to climate change, new study says
- The greater bamboo lemur tends to feed on nutritious bamboo shoots, switching to the woody trunk of the plant only during the dry season.
- A longer dry season due to climate change could force them to subsist on this less-than-optimal food source for more of the year, potentially pushing this critically endangered species closer to extinction, according to a new study.
- This discovery could have implications for other threatened species, like the giant panda, that depend on one type of food.

As Northwest salmon economy teeters on brink, Trump gives it a push
- Northwest salmon fisheries are in trouble, impacted by warming oceans and overdeveloped, dammed and silted spawning rivers and streams.
- Pre-contact indigenous groups in the region once organized their societies around sustainable fishing tribal agreements that worked. More recently, under past presidential administrations, Canadian, US and tribal authorities came together to save the declining salmon fisheries.
- Especially successful have been federally funded local, state and tribal programs, administered by NOAA, that protect and restore Northwest spawning streams — an investment in habitat and healthy local economies.
- Trump’s 2018 budget would cut all those programs, though for now Congress has restored them. However, politicians and regulators are concerned that Trump’s abandonment of Northwest fisheries and local economies will persist through his administration.

Unfair trade: US beef has a climate problem
- Across the globe, beef consumption, is seeing rapid growth, fed by cheap imports and served by an industrialized agricultural global trade model that’s been linked to a host of environmental impacts, climate change chief among them.
- Beef consumption in previously meat-light countries like Japan presents profit opportunities for the global beef industry. But scientists and activists argue that increasing beef consumption and industrial farm production go against efforts to combat climate change.
- President Trump’s recent decision to pull out of the Trans-Pacific Partnership (TPP), a global trade deal, upset the US beef industry’s plans of expanding into lucrative Asian markets, including Japan, calling into question if, or when, a future deal will be signed.
- TPP, like other global trade treaties, fails to acknowledge climate change or include mechanisms to curb it. Critics say TPP (which continues to be negotiated by 11 nations) and future trade deals must change radically — protecting not only business and the economy, but the environment.

A lingering ‘legacy’: Deforestation warms climate more than expected
- Tropical deforestation results in the release of not only carbon dioxide but also methane and nitrous oxide, leading to greater-than-anticipated warming of the global climate.
- The study compared emissions from land conversion with those from burning fossil fuels for energy and other sources.
- The researchers found that tropical deforestation at current rates could cause a 1.5-degree Celsius rise in global temperatures by 2100.

Healthy soils can boost food security and climate resilience for millions (commentary)
- Drylands take centre stage this week as world leaders gather in Ordos, in the Inner Mongolia region of China, for the thirteenth session of the Conference of the Parties to the UN Convention to Combat Desertification (UNCCD COP13).
- The health of many dryland ecosystems has declined dramatically over recent decades, largely due to unsustainable farming methods, increasing drought, deforestation, and clearance of natural grasslands.
- Changing the way drylands are farmed to conserve life underground is the only way of restoring these ecosystems and the agricultural outputs they sustain.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Modern Fish Act: boon to recreational fishing or risk to U.S. fishery?
- The Magnuson-Stevens Fishery Conservation and Management Act sets strict, scientifically adjusted, annual catch limits on U.S. commercial, charter and recreational fisheries in order to sustain saltwater fish stocks, and is seen as a model of fishery management globally.
- The Modern Fish Act (MFA), a bill introduced in the U.S. House in April, would do away with limits on recreational fishermen, who argue they have no impact on fishery stocks. Environmentalists, however, say the MFA introduces legal loopholes that would allow for uncontrolled fishing at potentially unsustainable levels that could cause stocks to crash.
- Critics also say that the MFA muddies the waters between federal and state management, and allows political and economic considerations to override science in management decisions. The bill is still moving through Congress, and its chances for passage are presently unknown.
- The Trump administration has already made moves to undermine scientifically arrived at recreational fishing limits. Its Commerce Department overruled a NOAA limit on the red snapper season in the Gulf of Mexico, a ruling experts say could delay the fishery’s recovery.

Ever wondered how much your pet’s diet impacts the environment?
- There are approximately 163 million dogs and cats kept as pets in the US, and it’s safe to assume even most vegetarians feed their pets some kind of non-vegetarian food product, given that dogs and cats are both carnivorous species.
- That got University of California, Los Angeles (UCLA) geography professor Gregory Okin wondering: Just how bad is the production of pet food for the environment?
- Meat production has well-documented impacts on the environment, as Okin notes in a study he published this month in the journal PloS ONE: “Compared to a plant-based diet, a meat-based diet requires more energy, land, and water and has greater environmental consequences in terms of erosion, pesticides, and waste.”

Canary in the Arctic coal mine: warming harms migrating red knot
- The Arctic is warming faster than any other part of the world, and its ecosystems are changing quickly, with shifts in the timing of insect hatches, plant growth and more.
- Those changes are impacting migratory species that move between the Arctic, the tropics and temperate zones. One such species is the red knot, a shorebird whose Arctic food supply and stored energy have been reduced due to climate change.
- A recent study found that young red knots (Calidris canutus) have shrunk by about 15 percent since 1985. This shrinkage includes a smaller beak which jeopardizes the juvenile birds’ survival as they dig for bivalves.
- Researchers have detected a variety of global warming risks to species as they move from tropical wintering and Arctic summering grounds, and along migratory routes, including shrinking tundra; rising seas; increasingly extreme weather; ocean acidification; and changes to specialized environments, such as temperate stopover havens.

Trump budget threatens Zimbabwe climate change resilience programs
- President Trump has threatened to cut U.S. aid to developing nations by a third. This could impact Zimbabwe which receives $150 million annually to decrease food insecurity for 2.1 million people.
- Aid to Zimbabwe is important to rural farmers, victims of escalating drought due to climate change. USAID finances dams and irrigation projects, making agriculture sustainable.
- The 2018 budget isn’t due to be finalized by Congress until October 1, 2017, leaving Zimbabwe’s people in uncertainty as to the direly needed aid.
- What seems certain is that the climate resilience program will not be expanded to meet the needs of yet to be served Zimbabwean communities.

Economic impacts of climate change on global fisheries could be worse than we thought
- Previous research has shown that global warming will cause changes in ocean temperatures, sea ice extent, salinity, and oxygen levels, among other impacts, that are likely to lead to shifts in the distribution range and productivity of marine species, the study notes.
- In all, the UBC researchers found that global fisheries could lose approximately $10 billion in annual revenue by 2050 if climate change continues unchecked — a 10 percent decrease, which is 35 percent more than has been previously estimated.
- Countries that are most dependent on fisheries to feed their populations will experience the biggest impacts, according to the study.

Rising CO2 is reducing nutritional value of food, impacting ecosystems
- As CO2 levels rise, so do carbohydrates in plants, increasing food’s sugar content. While carbon-enriched plants grow bigger, scientists are finding that they contain proportionately less protein and nutrients such as zinc, magnesium and calcium.
- A meta-analysis of 7,761 observations of 130 plant species found that overall mineral concentrations in plants declined by about 8 percent in response to elevated CO2 levels — 25 minerals decreased, including iron, zinc, potassium and magnesium.
- New research found that as atmospheric CO2 rose from preindustrial to near current levels, the protein content in goldenrod pollen fell by 30 percent. Bees and other pollinators rely heavily on goldenrod as protein-rich food for overwintering. The loss of pollinators could devastate many of the world’s food crops.
- Research into the correlation between CO2 concentrations and the nutrient content of food is in its early stages. More study is urgently needed to determine how crops and ecosystems will be altered as fossil fuels are burned, plus mitigation strategies.

Climate change a significant, growing threat to health, says US report
- A Climate and Health Assessment presented at the White House by the US Global Change Research Program revealed wide-ranging climate change health impacts.
- Every American is vulnerable, but low income people, certain ethnicities, Indigenous people, the young, elderly, and pregnant women are disproportionately at risk.
- The report is meant to help policymakers generate and implement a proactive response to the many escalating and evolving health impacts due to climate change.

Scientists: stop treating population growth as a ‘given’ and empower women

Climate change, biodiversity loss, resource depletion, water scarcity, and land issues: almost all of the world’s environmental problems are underpinned by too many people inhabiting a finite planet. A new study in the Proceedings of the Royal Society B warns that overpopulation—combined with over-consumption—is threatening to push the entire globe into “a collapse of global […]
From ‘fertilizer to fork’: food accounts for a quarter of the world’s greenhouse gas emissions

Children stand in sweet potato fields in Indonesian New Guinea. A new report finds that poor and small-holding farmers are most vulnerable to the impacts of climate change. Photo by: Rhett A. Butler. Growing, transporting, refrigerating, and wasting food accounts for somewhere between 19-29 percent of the world’s greenhouse gas emissions in 2008, according to […]
Food security in developing world threatened by climate change

If swift action is not taken to prepare farmers in the developing world for hotter, drier, shorter growing seasons, climate change may threaten the lives of hundreds of millions of people by 2050. People in Africa and South Asia are particularly at risk of further impoverishment and hunger in a warmer world. According to the […]
