To survive climate change, scientists say protected areas need ‘climate-smart’ planning
- Climate change is threatening the effectiveness of protected areas (PAs) in safeguarding wildlife, ecosystem services and livelihoods, with scientists now calling for the incorporation of “climate-smart” approaches into the planning of new and existing PAs.
- Key approaches to developing a network of climate-smart PAs include protecting climate refugia, building connectivity, identifying species’ future habitats and areas that promote natural adaptation. These approaches rely on science-based spatial models and prioritization assessments.
- For example, the Climate Adaptation and Protected Areas (CAPA) initiative supports conservationists, local communities and authorities in implementing adaptation measures in and around PAs across Africa, Fiji and Belize.
- Experts emphasize that climate-smart conservation plans must address immediate local needs, engage diverse stakeholders through transboundary collaboration, and rapidly expand across freshwater and marine ecosystems, especially in the Global South.
Record-breaking heat wave due to climate change hits Iceland & Greenland: Scientists
In May, both Iceland and Greenland experienced record-breaking heat. A new rapid analysis has found that the heat wave in both regions was made worse and more likely in today’s warmer climate. The analysis was conducted by World Weather Attribution (WWA), a global network of researchers that evaluates the role of climate change in extreme […]
Indonesian women sustain seaweed traditions in a changing climate
- The women of Indonesia’s Nusa Penida and Nusa Lembongan islands have harvested seaweed for generations.
- Climate change and tourism development now threaten seaweed cultivators’ centuries-old practices.
- In the face of these changes, seaweed cultivators are working with tourism operators and coral-conservation groups to preserve, and adapt, their traditional practices.
Real-world return on climate adaption investments wildly underestimated, report finds
- Since 2015’s Paris climate agreement, poor, climate-vulnerable nations have made a case for wealthy, industrialized nations (responsible for most climate change) to pay hundreds of billions for climate adaption and resilience. But while making big promises, actual funding by wealthy nations has repeatedly fallen far short of what’s needed.
- One possible reason: The real-world value of adaption and resilience projects has long been grossly underestimated due to incomplete data. A new study uses a novel methodology to put a comprehensive dollar value on such projects. It found that every $1 invested yields $10.50 in environmental and social benefits over a decade.
- Known as the “triple dividend of resilience,” this new methodology counts not only avoided climate change damages, but also economic gains (such as improved infrastructure and job creation) as well as broader environmental enhancements (improved public health and biodiversity protections, for example).
- It’s hoped this new analysis will offer policymakers and NGOs leverage at November’s COP30 climate summit in Belém, Brazil, as they try to convince wealthy nations and financial institutions to unlock the many billions needed by vulnerable nations in adaption and resilience funding to weather escalating climate change impacts.
Is rising CO2 really bad for the world’s drylands? Mongabay podcast probes
Increased carbon dioxide emissions since industrialization have accelerated climate change, and its widespread negative impacts have been reported worldwide. But the rising concentrations of CO2 in the atmosphere are also making some parts of our planet greener in what’s called the CO2 fertilization effect. Some politicians claim this effect means more atmospheric CO2 is doing […]
Urban forests in Niger’s schoolyards serve climate resilience and education
- Trees growing school yards in Niger’s two largest cities are helping to cool classrooms and illustrate the value of urban forests.
- A study of green spaces across 60 schools in Niamey and Maradi two cities found that trees in schools help mitigate extreme heat, a source of food and income, and enhance learning.
- School yards represent a form of protected area within cities, and the study’s author encourages municipal and educational authorities to integrate urban forestry into planning for school infrastructure.
Report urges stricter mining standards to manage climate and social impacts
- A new report from the Mining Observatory finds that key mining states in Brazil are highly exposed to climate risks, water insecurity and environmental degradation.
- Mining for transition minerals can in some cases exacerbate the impacts of climate change on ecosystems and local communities in the states of Pará, Minas Gerais, Goiás and Bahia.
- Researchers told Mongabay that without better socioenvironmental safeguards, the expansion of transition minerals mining represents a “major” threat to these communities’ way of life and the preservation of ecosystems.
- The report urged governments and companies to implement stronger policy frameworks, climate adaptation strategies, robust oversight and better mechanisms to involve rights-holders in key decisions.
Ground-level ozone wreaks havoc on warming planet
Ozone as a layer several kilometers up in the atmosphere protects living beings, including humans, from ultraviolet rays. But its accumulation at ground level can be very dangerous, Mongabay contributor Sean Mowbray explains in an article published in April. Ground-level, or tropospheric, ozone forms when methane, nitrogen oxides, carbon monoxide and volatile organic compounds react […]
Science lays out framework to assess climate liability of fossil fuel majors
- In recent decades a growing number of lawsuits have been launched by states, cities and other government entities to hold fossil fuel companies financially liable for the climate harm caused by the greenhouse gas emissions their products produce.
- But those efforts often come up against challenging legal arguments made by the companies saying that their actions and emissions cannot be scientifically linked to specific climate change-driven extreme weather events.
- Now, fast-advancing attribution science is offering answers to those legal arguments. A new study has created a framework that connects the emissions over time of the world’s largest fossil fuel companies — BP, ExxonMobil, Chevron, Saudi Aramco and Gazprom — to rising temperatures and specific heat-related climate disasters.
- Researchers say that, in time, this framework for assigning attribution and financial damages could be extended to specific fossil fuel companies and a range of climate change-intensified extreme events such as hurricanes, flooding, sea-level rise and wildfires. The framework has yet to be tested in court.
Report shows policy gaps in safeguarding the carbon rights of forest communities
- An absence of government legal and policy reforms is impacting the rights of Indigenous, Afro-descendant peoples and local communities associated with carbon programs in 33 countries, according to a recent report.
- More than half of the reviewed countries don’t have carbon trading regulations, and nearly half have no legal provision to recognize the communities’ right to free, prior and informed consent, the report found.
- It emphasizes safeguarding carbon rights to ensure the communities’ consent and rights over decision-making as countries prepare to comply with the Paris Agreement’s market mechanism for trading high-quality carbon credits.
- Although the voluntary carbon market is faring comparatively better in ensuring these rights, researchers say there still remains much to do in terms of addressing grievances and making sure people stay informed.
Solutions needed as climate change & land use fuel global crop pest menace
- Climate change is colliding with land use practices, deforestation and biodiversity loss to drive a rapidly growing threat of crop pests.
- Future warming of 2° Celsius (3.6° Fahrenheit) above preindustrial levels (likely by the 2040s or 2050s, according to current projections) could see substantial losses of staple crop yields for wheat (an estimated 46% loss), rice (19%) and maize (31%) due to pest infestations, according to a recent paper.
- Temperate regions are likely to see the greatest increases in crop pests as warming creates conditions for migrating subtropical species to establish themselves in previously unhabitable areas.
- The authors underline the need for more pest monitoring, diversification of farmland crops and biotechnological solutions to meet this growing threat.
How to conserve species in a much hotter world
By 2075, we will be living on a planet that is much hotter, possibly 3-5° Celsius (5.4-9° Fahrenheit) hotter than the preindustrial average. But how can humanity help nature improve its climate resilience in the years to come? Mongabay’s Jeremy Hance found some answers after interviewing several conservationists. “In 50 years, it’s entirely possible that […]
Global warming hits hardest for those who can’t escape it
- The world’s most vulnerable people, including refugees, migrants and the poor, increasingly face threats related to climate change.
- Many lack the ability to move away from impacts like heat, flooding and landslides.
- A new study reveals a lack of data showing the causes of this involuntary immobility.
- Experts say governments and organizations can invest in low-cost interventions aimed at reducing suffering.
Agroforestry can reduce deforestation, but supportive policies matter, study finds
- Agroforestry is recognized as a way to boost local biodiversity, improve soils and diversify farming incomes. New research suggests it may also benefit nearby forests by reducing pressure to clear them.
- The study found agroforestry has helped reduce deforestation across Southeast Asia by an estimated 250,319 hectares (618,552 acres) per year between 2015 and 2023, lowering emissions and underscoring its potential as a natural climate solution.
- However, the findings also indicate agroforestry worsened deforestation in many parts of the region, highlighting a nuanced bigger picture that experts say must be heeded.
- Local social, economic and ecological factors are pivotal in determining whether agroforestry’s impacts on nearby forests will be positive or negative, the authors say, and will depend on the prevalence of supportive policies.
Elevator to extinction (cartoon)
As climate change pushes montane species upslope in a bid to escape warming temperatures, species, including birds, occupying the highest altitudes could be left with nowhere to go, making them the most prone to extinction.
Diverse forests and forest rewilding offer resilience against climate change
- Recent studies from two long-running planted forest experiments in China and Panama find that increasing tree diversity in reforestation efforts can boost resilience in the face of climate change, among other benefits.
- Researchers elsewhere propose a “rewilding-inspired forestry” approach that aims to restore biodiversity, aid climate mitigation and bolster forest ecosystems — an approach that requires a significant shift from current forestry practices.
- However, scientists underline that while reforestation and forest rewilding can contribute to curbing climate change, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests.
Heat wave scorches parts of India with record temperatures
Several cities across India saw temperatures top 40° Celsius, or 104° Fahrenheit, this past week, with some areas exceeding 46°C (114.8°F). Delhi experienced a heat wave for three consecutive days, recording its warmest April night in three years, with temperatures 5-6°C (9-10.8°F) above normal for the period. Many areas in the country’s northwest remain on […]
In Panama, Indigenous Guna prepare for climate exodus from a second island home
- The island of Uggubseni, located in Panama’s Guna Yala provincial-level Indigenous region, spent the month of February participating in region-wide celebrations to mark the centenary of a revolution in which the Indigenous Guna expelled repressive Panamanian authorities and established their autonomy in the region.
- Though the intervening century has left the Guna’s fierce independence undimmed, new existential threats now face Uggubseni: Accelerating sea level rise due to human-caused climate change and overpopulation.
- A consensus now exists among Uggubseni residents that moving inland is necessary; but it remains unclear whether the government will be able to deliver the necessary funding and support.
- Although 63 communities nationwide are at risk of sinking due to climate change, there’s only one other model for climate relocation: In June 2024 the Panamanian government relocated around 300 families from Gardi Sugdub, another island in Guna Yala, to a new community on the mainland where problems remain rife.
How is conservation preparing for a much hotter world? Experts share
- Fifty years from now, in 2075, the world will be considerably hotter, perhaps as much as 3-5° Celsius (4.5 to 9° Fahrenheit) above the pre-industrial average.
- Experts say we need to focus on building greater resilience into ecosystems now to help species get through the next half century.
- We should be protecting large landscapes, including altitudinal gradients, according to experts.
- We should also be focusing on good management, community relations, rewilding and restoration.
122 companies responsible for a third of present day sea-level rise: Study
What’s new: Almost half of global average temperature rise and a third of sea-level rise can be attributed to the “carbon majors,” the world’s 122 largest fossil fuel and cement producers, a recent paper shows. What the study says: Research from U.S.-based science advocacy NGO Union of Concerned Scientists (UCS) used climate-carbon cycle models, and […]
Colombian farmers switch from coffee to cacao as temperature and prices soar
- Due to rising temperatures and climate change, small-scale coffee farmers in Colombia are increasingly planting cacao.
- Cacao faces fewer immediate challenges compared to coffee, which is prone to pests and diseases, and can integrate well into agroforestry systems. However, agronomists warn that the switch to cacao can lead to clearing forests and increasing chemical inputs in order to expand existing plantations.
- Higher profits, the high prices of cacao in the market, and the increasing expenses needed to manage coffee crops are also factors pushing small-scale farmers towards the switch.
- Although coffee remains Colombia’s most important agricultural product, cacao is emerging not just as an alternative, but as a defining crop in Colombia’s evolving agricultural future, say agronomists.
Farmers turn to living ‘yam sticks’ to grow their crop and spare the forest
- In major yam-producing areas such as West Africa and the Caribbean, the tuber is traditionally grown using sticks as scaffolds for vine growth, which are traditionally cut from the forest, causing deforestation.
- Scientists and yam breeders are trialing ways to replace these sticks through agroforestry, introducing living supports that can also improve the soil and provide other benefits to farmers.
- Trials using plants such as pigeon pea and bitter damsel as living yam sticks have shown potential.
- However, conservationists say that entrenched traditional farming methods and a lack of funding to promote more sustainable approaches are preventing living vine sticks from widespread application.
Longer periods of drought threaten Brazilian amphibians
- According to a study, global warming will increase droughts in up to 33% of the habitats of frogs, toads and treefrogs; in Brazil, the strongest impacts will be felt on the Amazon and the Atlantic Forest — precisely those with the greatest diversity of amphibians.
- Drought and amphibians are not a viable combination: These animals depend on water and humidity to survive; without that, they may dehydrate in a few hours and die.
- The Atlantic Forest is home to more than 700 species of anuran amphibians, more than 50% of which are endemic; in the Amazon, the greatest focus of potential extinction is the Arc of Deforestation.
- In a warmer and drier climate, the question is whether there will be time for these animals to adapt or evolve over generations to survive these new conditions.
Colombia’s coffee farmers try to balance innovation and tradition to adapt to climate change
- Researchers and coffee farmers in Colombia are trying to find strategies to adapt to unpredictable weather, rising temperatures and erratic rainfall, which are disrupting Colombia’s coffee industry by fueling pests and diseases like the coffee berry borer and coffee leaf rust.
- Cenicafé, the national coffee research center, is continuously developing new hybrid coffee varieties that are resistant to diseases and climate change for farmers, but pests are evolving, requiring more research and genetic diversification.
- Some farmers are restoring the much slower traditional shade-grown coffee practices through reforestation and agroforestry, which help them access premium high-end coffee markets while tackling and adapting to climate change.
- With the limited options presented, some researchers say coffee growers must at times choose between high-yield hybrids or eco-friendly organic farming, weighing sustainability against economic survival.
In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.
Photos: Ethiopian farmers blend tradition, innovation to sustain centuries-old agriculture
- For more than 400 years, the people of the Konso highlands in Ethiopia have used terracing and traditional farming methods to adapting to their harsh environment, building a globally recognize agricultural system on steep, erosion-prone land.
- However, in recent decades, climate change has altered once-predictable weather patterns, making it harder for small-scale farmers to maintain their traditional farming practices and secure their livelihoods.
- Farmers are adjusting to changing weather patterns by blending traditional farming methods with new techniques, aiming to safeguard their livelihoods and ensure the land remains fertile and productive.
- While experts acknowledge farmers’ efforts to adapt, they warn that these efforts alone will not suffice as climate change impacts intensify, stressing the need for external support to sustain local livelihoods and preserve traditional farming practices.
Hotter weather threatens heart health, Australian study warns
Extreme heat is putting people in Australia at serious risk of heart problems and premature deaths, according to new research. As the climate warms, rising temperatures could more than double Australia’s burden of cardiovascular diseases by 2050, unless greenhouse gas emissions are reduced, and people take measures to adapt to the heat, researchers found. Cardiovascular […]
African forum on urban forests calls for greater access to green spaces
- Researchers policymakers, and civil society gathered at the African Urban Forest Forum in Johannesburg to discuss the role of urban forests in African cities.
- The forum centered on how trees can make cities more climate-resilient, providing more equitable access to green spaces, and finding sustainable financing strategy for urban forests.
- In a declaration at the end of the forum, participants called for greater collaboration to increase tree canopy cover in cities and address the combined challenges of rapid urbanisation, climate change and historical inequalities.
Africa’s last tropical glaciers are melting away along with local livelihoods
- Africa’s remaining tropical glaciers are rapidly disappearing as greenhouse gas emissions drive global warming.
- New maps published by Project Pressure show the Stanley Plateau glacier, in Uganda’s Rwenzori Mountains, lost nearly 30% of its surface area between 2020 and 2024.
- The Rwenzoris’ glaciers are a vital source of water for more than 5 million people living in the plains below the mountain range; they also have cultural significance.
- Project Pressure’s ongoing surveys, carried out in collaboration with the Uganda Wildlife Authority, are intended to provide local authorities with data needed to adapt to the loss of the glaciers and other impacts of climate change.
Bleak future for Karoo succulents as desert expands in South Africa
- Recent population surveys show continued decline in two desert-adapted succulent tree aloe species, with conservationists fearing for the state of an understudied third species.
- A years-long drought has accelerated spreading dust-bowl conditions following decades of mining and heavy grazing, with grave consequences for endemic succulents.
- A conservation triage should prioritize cultivating at-risk species in nurseries and botanical gardens, many of which are unlikely to survive reintroduction into their natural habitats.
Australia faces inflation, agriculture losses after Cyclone Alfred
The Australian government has warned of impacts to the country’s economy in the wake of Cyclone Alfred that caused massive losses to infrastructure, agriculture and the dairy industries when it struck in late February. The horticultural industry was among the worst hit, with strong winds toppling and damaging hundreds of orchard trees, and floodwaters inundating […]
Sri Lanka communities left gasping for climate mitigation support
- Despite being highly vulnerable to climate risk, Sri Lanka is slow to tap into climate funding due to a range of issues including inadequate data systems, institutional weaknesses and limited capacity to design and implement viable projects.
- Sri Lanka’s disaster management units require significant funding to initiate mitigation measures amid increasing climate change impacts, where the most vulnerable populations bear the brunt of climate impacts.
- The island’s nationally determined contributions (NDCs) are still to be submitted, adding to delays in pursuing climate finance opportunities for Sri Lanka.
- With many people vulnerable to climate change impacts and lacking adaptive capacity, building resilience calls for much higher financial investments in climate adaptation.
Collaboration, data and tracking move Africa’s Great Green Wall toward its goal
- After years of delays due to insufficient funding and prevailing conflicts, the Great Green Wall in the Sahel, aimed at preventing desertification, gained momentum with an accelerator program announced in 2021.
- As part of the accelerator, efforts are underway to address delays, improve monitoring progress of different projects that are part of the GGW initiative, track them by country, and evaluate their effectiveness, including building a new online database.
- GGW partners say they hope the harmonized monitoring and progress tracking can help sustain funding and realize the objectives of the ambitious initiative in the Sahel.
Agroforestry stores less carbon than reforestation, but has many other benefits, study finds
- New research finds that a reforestation and agroforestry project on Indigenous land in Panama missed its carbon sequestration goal, but returned better-than-average results and had many other benefits.
- The study found that tree planting had higher carbon storage, but agroforestry brought benefits to the local community in terms of extra income and food security.
- Fire was the biggest reason why the carbon goal was missed, which is an increasingly common challenge for carbon projects worldwide due to climate change.
- Researchers say project funders need to work closely with local communities to align goals around carbon storage and livelihoods.
Lake Chad isn’t shrinking — but climate change is causing other problems
- Contrary to popular conception, Lake Chad is not shrinking; new research shows that the volume of water in the lake has increased since its low point in the 1980s.
- However, more intense rain in the region, coupled with the impacts of historic drought, increases the risk of flooding.
- The region is also plagued by continuing conflict and insecurity, making to harder for people to adapt to the impacts of climate change.
- A Lutheran World Federation project is working with communities in the Lake Chad Basin on sustainable agriculture and fisheries, land restoration, conflict resolution and more.
In Kenya, grassland restoration can help reduce conflict, study says
- A study says that grassland restoration, which uses nature-based solutions for climate adaptation, can enhance Kenyan farmers’ security, reduce conflicts and mitigate wildlife retaliatory actions.
- Researchers report that grasslands in Kenya provide 60% of fodder for livestock and 70% of wildlife, requiring proximity for survival.
- Rangelands are degrading, causing animals like elephants and zebras to enter farms for food, causing conflict with farmers; healthier rangelands would prevent wildlife from entering farms.
- The researchers call for including grassland restoration in both national and international environmental plans, specifically in Kenya, along with funding and resources for this effort; additionally, they advocate for policies that consider human-wildlife conflicts and social issues while being sensitive to the specific challenges men and women face in these regions.

Those killed during Elvis’s passage were involved in “lightning events” in Vohibato district in eastern Madagascar, according to […]
Mexican fishers relocate in wake of sea level rise, raising job concerns
- In the southern Mexican state of Tabasco, most residents of the El Bosque community have been relocated after their homes were destroyed by coastal erosion.
- Community members have expressed concern about job security, as the new site is 12 kilometers (7.4 miles) away from the sea and residents cannot as easily fish, which they depend on for their livelihoods.
- While planned relocation has emerged as a critical strategy to protect those impacted by climate change, reports have shown relocation does not always reduce socioeconomic pressures.
- Although fishers from El Bosque are concerned about the impact of the relocation on their livelihoods, some see it as an opportunity for younger generations to seek alternative livelihoods and better opportunities.
Explosive ‘bomb cyclone’ pummels Europe, hitting UK hardest
Back-to-back storms have ravaged the U.K. and neighboring Ireland and France, causing torrential rains, power outages and flooding the past several days and overall “wild weather,” the Associated Press reported.

Brazil’s ‘innovative’ reforestation agenda discussed in Davos (commentary)
- At the World Economic Forum 2025 in Davos this week, a coalition of leaders from across Brazilian sectors will discuss the integrated, pre-competitive agenda needed to scale forest restoration.
- Forest restoration is a key part of successful climate action, providing carbon removal, biodiversity protection and sustainable economic growth, but it requires immediate investment and action, the authors of a new op-ed write.
- Brazil’s coordinated approach across business, finance, and conservation sectors has resulted in approximately $528 million in restoration investments in the past 18 months, setting a global example for impactful forest restoration and climate action.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
In DRC bid to grow more food, smallholders are overshadowed by industrial farming
- More than 25 million people in the Democratic Republic of Congo suffer food insecurity, largely due to insecurity and inadequate infrastructure.
- South Ubangi province is mostly free of the armed conflict prevalent in the eastern part of the country, but nearly three-quarters of its residents face high levels of food insecurity.
- Agriculture is the livelihood for 80% of people in the province and the government is exploring ways to reinforce their production.
- For the most part, this means incentivizing massive agro-industrial plantations, even at the expense of overlooking smallholder farmers, but some experts say this won’t guarantee improved food security.
Can carbon markets save forests?
Voluntary carbon markets generate funding intended for forest conservation, but are they delivering real-world results for climate, biodiversity, and communities? This special issue offers critical insight into the ongoing debate over the integrity of the trade of credits derived from forest carbon projects and their role in addressing climate change and halting deforestation. In 2023, […]
Climate change forces Jakarta fishing families to marry off young daughters
Climate change is driving families on Indonesia’s northern Javanese coast toward child marriage as a survival strategy amid dwindling fish stocks and increasing economic hardships, two Mongabay reports show. Mongabay contributor Maulia Inka Vira Fendilla traveled to North Jakarta’s Kalibaru neighborhood in 2023 and met Janah and Jaroh, sisters who were both married off at […]
From Bhutan to Nigeria & Kenya, women endure climate change differently than men
- Research shows that globally, women and girls suffer greater effects of climate change and environmental disasters than men; at the same time, women environmental journalists often face greater obstacles on the job, and women’s voices are often missing from stories about climate change.
- Three recent Mongabay fellows, all women, report on specific examples from their home countries (Bhutan, Nigeria, Kenya) in which women disproportionately experience the effects of climate change and extreme weather.
- In all three examples, women exhibit a perseverance that ensures their own and their families’ survival — and sometimes aids their own independence and resourcefulness.
Young people in Africa call for a fair increase in funding for climate adaptation
- Young activists in Africa are calling for doubling adaptation financing for climate change.
- The youths presented their demands during COP29, dubbing it the ‘six30 campaign’.
- Experts say the adaptation funds for the continent is seriously underfunded.
Philippines’ ‘extraordinary’ typhoon season was climate-fueled: Scientists
From late October to November this year, six consecutive tropical cyclones battered the Philippines, affecting 30 million people.

Researchers propose a ‘circular economy’ solution to housing affordability against climate change
A global housing affordability crisis is underway, so when the Center for Demographics and Policy at Chapman University in the U.S. released a report this year highlighting the “disastrous” state of housing affordability for 94 markets — where median home prices far exceed median wages by many times, making housing much more expensive for the […]
Land use change impacting seven planetary boundaries, solutions urgent, say scientists
- A new scientific report lays bare the stark impacts of land-system change and land degradation on planetary health, while also offering solutions to these problems. The report was published on the eve of the 16th session of the UN Convention to Combat Desertification, running Dec. 2-13 in Riyadh, Saudi Arabia.
- Seven of nine planetary boundaries are now adversely impacted by unsustainable land use and other land practices, the report finds. Six of those boundaries are already transgressed, having moved beyond their safe operating space for humanity and into the high-risk zone.
- Scientists warn that the seriously degraded land use boundary, interacting with the other transgressed planetary boundaries, could result in a domino-effect that may rapidly push Earth systems past dangerous and irreversible tipping points, threatening life as we know it.
- Unsustainable agricultural practices are a leading driver of land use degradation globally, responsible for vast amounts of greenhouse gas emissions, the majority of deforestation and freshwater use. Urgent measures are needed to restore ecosystems, shift to sustainable agriculture, and prevent further degradation.
PNG climate migrants sail away with native trees to their new home
Residents of the Carteret Islands in Papua New Guinea are on a “green migration,” contributor Thibault Le Pivain reports for Mongabay.

India, U.K. deal with storms that are ‘symptom of our changing climate’
India is bracing for intense rainfall over the next few days as a deep depression over the Bay of Bengal is set to intensify into what will be called Cyclone Fengal by Nov. 29, according to local media reports. The India Meteorological Department (IMD) said the cyclone is likely to pass near the coast of […]
As climate change upends Ethiopia’s pastoral wisdom, adaptations can help
- In the face of climate change, pastoral and agropastoral communities in eastern Ethiopia remain at the receiving end of worsening droughts and climate shocks that have taken a toll on animal rearing and traditional livelihoods.
- For generations, pastoralists and agropastoralists across the country have used traditional knowledge and weather forecasting for preparedness and drought conditions.
- But these techniques are no longer as effective in the face of frequent unpredictable dry spells and population pressures on pasture.
- Researchers suggest combining this traditional knowledge with innovative strategies to help pastoralists gather real-time data on water conditions that can be key to drought adaptation in the region.
Cities are climate solution leaders: Interview with Vancouver’s Gregor Robertson
- 2024 will likely be the hottest year on record, surpassing the heat record set in 2023. The resulting extreme heat waves, floods, droughts and wildfires took a terrible toll in death, global suffering and economic loss.
- The biggest climate change impacts have by far been in the world’s cities. And the world’s cities have responded proactively, becoming climate solution leaders, even as national governments have dragged their feet for nearly three decades.
- If nations and investment banks offered billions in financing to boost climate work now underway in cities, that effort could then be vastly scaled up, said Gregor Robertson, former mayor of Vancouver, Canada, and a special envoy to the Coalition for High Ambition Multilevel Partnerships. This is an exclusive Mongabay interview.
In a Noah’s Ark move, PNG migrants bring thousands of trees to safer ground
- Facing sea level rise and food insecurity, 17 families from the Carteret Islands have relocated to nearby Bougainville, bringing hundreds of specimens of trees and plants, representing dozens of species, across a small stretch of ocean.
- They’ve planted more than 175,000 plants, breathing life into a forest on new lands donated by the Catholic Church.
- This “green migration” is helping them preserve their lifestyle and identity, sources say, echoing the journey of early Polynesian settlers who carried “canoe plants” as they sailed and settled across the Pacific.
- Scientists say green migrations could become part of climate relocation planning, but there also needs to be careful consideration of whether species can be moved and become unsustainably invasive.
Recent surge in methane emissions driven by microbes: Study
Emissions of methane, a greenhouse gas several times more potent than carbon dioxide, increased at record-high rates between 2020 and 2022. A new study suggests that rather than fossil fuels, microbes were responsible for this recent methane surge. Until the early 2000s, fossil fuel production drove much of the increase in atmospheric methane, study lead […]
Organizations tackle droughts, floods in Brazil by planting forests
- Many areas of Brazil have been hit with severe droughts and floods in recent years; scientists say climate change is increasing the incidence of extreme weather events.
- Forests protect against erosion and pollution and help store water in soil and aquifers, buoying water security.
- Organizations across the country are leading efforts to reforest cleared areas — particularly along rivers and other water sources —to mitigate the damaging effects of droughts, floods and other effects of climate change, as well as safeguard and improve habitat for wildlife.
- Experts and stakeholders say broader support is needed at the federal level, while a representative of Brazil’s Ministry of Environment and Climate Change says the government is rolling out conservation plans of its own.
‘We are not asking for handouts,’ Rwandan President Kagame says at COP29
BAKU, Azerbaijan – The debate around international climate finance is often interpreted to mean developing countries demand wealthier nations cover the growing climate bill. However, at the ongoing U.N. Climate Change Conference in Baku, Azerbaijan, African leaders argue they are not seeking free money. Instead, they want the world to recognize the true value of […]
Shipping emissions reduction sheds light on marine cloud geoengineering
- Unprecedented marine heat waves in the North Atlantic have been driven in part by a recent drop in shipping emissions, leading to a reduction in highly reflective marine clouds that had previously masked some of the warming from humanity’s greenhouse gas emissions, studies find.
- New limits on sulfur dioxide emissions from shipping, introduced by the International Maritime Organization in 2020, created an inadvertent “natural experiment” that is helping to improve models of the interaction between atmospheric aerosols, clouds and climate.
- The sulfur dioxide emissions reduction also provides the clearest test to date of marine cloud brightening (MCB) — a controversial geoengineering approach proposed to mitigate climate change. It shows that to be effective and avoid a dangerous termination shock, MCB would need to be continuous and sustained.
- Reducing atmospheric aerosol pollution has major benefits for human health, but will also inevitably lead to an unmasking of more dangerous climate warming. This means that improvements in air quality must simultaneously be coupled with decarbonization, experts say.
Grounded: A pilot who quit flying to help tackle climate change works to change aviation, for good
Todd Smith didn’t intend to quit his career as a commercial pilot, but a visit to the Quelccaya Ice Cap in Peru, which has been receding by about 60 meters, or 200 feet, per year, prompted a frank personal examination of the airline industry’s impacts on the planet. During a subsequent medical leave, he decided […]
African leaders at COP29 demand funding without further debt
BAKU, Azerbaijan — As developing countries grapple with increasing floods, droughts and other climate-related impacts, their limited financial resources are under considerable strain. This situation often leaves many governments with little choice but to borrow money to address the devastating effects of climate change. Developing countries have historically produced very few of the carbon emissions […]
U.S. policy experts confident of future climate action despite Trump election
- In 2015, the world came together to achieve the landmark Paris climate agreement. But in 2016, Donald Trump’s ascendency to the U.S. presidency stunned the world, as he promised to withdrew the U.S. from the Paris accord and moved to disrupt action on climate change.
- The Biden administration worked to reverse that damage, with the U.S. again taking a leadership role in global climate summits and passing the Inflation Reduction Act, one of the most ambitious U.S. laws ever to combat global warming and boost the post-carbon economy.
- Now, with Trump elected again, the world stands ready for his climate denialism, and his likely withdrawal of the U.S. for a second time from the Paris Agreement. Global momentum is expected to continue unabated, with alternative energy thriving, Brazil hosting COP30 in 2025, and China and the EU doubling down on climate action.
- In the U.S., “Just as we did during the last Trump administration, we are going to put a focus on our work with cities and with states and many private-sector leaders who stood tall then and stand tall now,” said Gina McCarthy, EPA administrator during Barack Obama’s second term, and managing co-chair of America Is All In, an NGO.
Africa needs COP29 funding & international finance reform to manage climate change (commentary)
- From 11 to 22 November, the world will be looking to leaders to ramp up action and financial support for nations on the frontlines of climate change.
- COP29 is billed as the ‘finance COP’ because it is time for countries to set a new global climate finance goal. Will Africa get the support it requires, this time?
- “It is important to acknowledge the significant role that the COPs play in addressing climate change [but] it is equally crucial to prioritize efforts aimed at comprehensively reforming the international financial infrastructure to ensure fair and just treatment of Africa,” writes Mongabay Africa’s program director.

At least 146 dead in back-to-back tropical cyclones in Philippines
Two tropical cyclones recently struck the Philippines one after the other, leaving at least 146 people dead, according to government reports. The country first felt the peak intensity of Severe Tropical Storm Trami (local name Kristine) on Oct. 24. The storm maintained sustained winds of up to 95 kilometers per hour (59 miles per hour) […]
Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.
More krill fishing and no new protected areas for Antarctic seas after latest talks
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) held its annual meeting Oct. 14-25 in Hobart, Australia.
- The international body comprised of 27 members is charged with conserving marine life in Antarctic waters, an area that is changing rapidly due to human-caused climate change.
- In 2009, the CCAMLR pledged to create “a representative network” of marine protected areas in the Southern Ocean, yet negotiations over four proposed MPAs have been at a standstill for years, due to repeated vetoes by the Chinese and Russian delegations.
- Despite a year of interim negotiations, CCAMLR members failed again at the latest meeting to reach agreement on creating any new marine protected areas and rolled back regulation of the burgeoning Antarctic krill fishery.
Botanical gardens play key role in biodiversity & climate conventions (commentary)
- “As world leaders and scientific institutions from across the globe gather to discuss the biodiversity crisis at COP16 and climate change at COP29 this fall, it’s critical that they do not neglect the important work that is already being done by one of the world’s key stewards of nature – botanical gardens,” a new op-ed argues.
- Botanical gardens have an important role to play in the overall effort to combat the dual climate and biodiversity crises and can offer important solutions, but they are often underutilized, despite housing a wide array of experts on plants and fungi.
- “At the rate the planet is warming, there is no time to leave their untapped potential behind,” writes the CEO of The New York Botanical Garden.

Indigenous perspectives and a fossil fuel phaseout treaty featured at Climate Week
The Mongabay Newscast traveled to Climate Week in New York City in September to document the perspectives of conservation NGOs, activists and policymakers hailing from Asia to African and the Amazon. On this episode, we share an array of views on the myriad topics discussed there, like improving conservation finance, an effort to popularize a […]
Coastal farmers in Bangladesh give up shrimp farming for agriculture to combat salinity
- The decades-long shrimp aquaculture on Bangladesh’s southwest coast, which negatively impacts the environment in many ways, including creating a freshwater crisis, is now losing its importance as the farmers are gradually inclining toward agriculture again.
- Increased salinity, both due to sea-level rise and diversion of the upstream flow of freshwater, and peer pressure had forced the coastal farmers to venture into shrimp cultivation about four decades ago.
- For the last couple of years, excessive salinity and repeated viral outbreaks in shrimp farms have pushed the farmers back to agro-based farming again.
- Crop diversification plays a positive role in addressing the changes; however, water shortage poses a big challenge in restoring agriculture.
Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.
Indigenous communities can decide for themselves on carbon market risks (commentary)
- It’s been a tough year for the voluntary carbon market, and last year was also challenging — scandals embroiled many carbon credit projects in 2023, and management malfeasance and staff abuse have affected projects, too, including ones based in Indigenous communities.
- Critics have put Indigenous communities at the forefront of critiques of carbon projects, suggesting that market-based approaches are inherently contrary to their worldviews, but this is not necessarily the case, a new op-ed argues.
- “Indigenous peoples should be free to see the voluntary carbon markets as a place of both risk and opportunity. We don’t want to suggest that present inequities will solve themselves, and indeed we worry about reform efforts stalling once the heat from the scandals cools a bit. The agenda we need now puts Indigenous self-determination at the top and supports it with honest assessment of risks and real investments in support,” the authors write.

A future where we might ‘get climate right’: A conversation with Ayana Elizabeth Johnson
Solving our ecological and climate problems looks a lot less like a techno-utopia and more like a mosaic of actions both to protect and restore nature, and to increase and safeguard human equity in the face of climate change, marine biologist Ayana Elizabeth Johnson says on Mongabay’s latest podcast episode. In other words, flashy technology, […]
Inaugural Planetary Health Check finds ocean acidification on the brink
- A first of its kind Planetary Health Check by an international team of scientists indicates that six of nine planetary boundaries are not only transgressed, but are moving further into zones of risk. In addition, recent research shows that a seventh boundary, ocean acidification, is on the verge of transgression.
- Intensifying ocean acidification spells problems for marine life, fisheries and economies. Based on current human CO₂ emission trajectories, this boundary may be breached in a few years, say experts. Others argue this threshold may already have been crossed, with regional acidification above safe limits.
- Together, the nine planetary boundaries identify limits within which Earth systems can operate safely to maintain the planet’s habitability. Transgressing boundaries heightens risks of breaching tipping points that would bring about irreversible shifts to the planet, threatening humanity and life as we know it.
- This inaugural Planetary Health Check is the first of yearly scheduled reports on the wellbeing of Earth systems. Annual reports are now needed due to humanity’s rapid crossing of planetary boundaries, and due to the urgency of providing up to date scientific data to policymakers.
Bangkok turns to urban forests to beat worsening floods
- Bangkok is launching city forests to help beat flooding by soaking up excess rainwater runoff.
- A new park slated to open in December will feature 4,500 trees, a floodplain and a weir to slow the flow of water; another newly opened $20 million city forest acts as a sponge during the monsoon season.
- Bangkok is sinking, and fast: according to the World Bank, 40% of the Thai capital could be flooded by 2030.
- The key to solving the city’s flooding problem is to learn to live with water, not to rid the city of water, says one landscape architect helping to launch the urban forests.
How coastal communities are adapting to sea level rise with ‘living shorelines’
Along the U.S. East Coast, communities are adapting to sea level rise with a promising approach called “living shorelines.” These projects bolster shorelines against stronger storms and higher tides with native plantings and natural materials like driftwood and even holiday trees. Maine Geological Survey coastal geologist Peter Slovinsky joins the Mongabay Newscast to describe several […]
Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.
Conserving & restoring waterways can mitigate extreme urban heat in Bangladesh
- Conserving existing wetlands and restoring urban waterways can be an effective way for urban planners to protect city residents from extreme heat.
- In Dhaka, as in other large cities, paved urban landscapes absorb heat and intensify the risk of heat waves. Areas of cities that are prone to such thermal intensity are known as “heat islands.”
- Urban sprawl frequently fills or covers wetlands and waterways as cities grow.
- Conserving green spaces is important to reducing urban heat and protecting people in cities from extreme heat, but conserving wetlands and waterways is even more effective.
As waterbodies lose oxygen, are we breaching a potential planetary boundary?
- A new perspective piece argues that aquatic deoxygenation — the depletion of oxygen in marine and freshwater environments — should be considered its own “boundary” in the planetary boundary framework first proposed by scientists in 2009. Human-caused nitrogen pollution and climate change have greatly worsened aquatic deoxygenation worldwide.
- The planetary boundary framework defines nine natural biophysical and biochemical system processes that maintain the resilience of the Earth system, allowing life to thrive. But each boundary includes limits within which humanity needs to safely operate.
- The paper’s lead author says that increased scientific understanding of dissolved oxygen in marine and freshwater environments shows that it regulates, and is regulated by many of the other planetary processes, which in turn warrants the inclusion of aquatic deoxygenation in the planetary boundary framework.
- The framework is a rapidly evolving theory. Whether aquatic deoxygenation is already indirectly taken into account by the existing framework, as some argue, or whether it should be considered as its own planetary boundary remains to be determined.
Cloud brightening over oceans may stave off climate change, but with risk
- Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.
- However, this solar radiation management (SRM) geoengineering technique is highly controversial, and experts say governance of MCB field experiments and deployment is needed now at the national and international levels.
- Ongoing efforts to include marine cloud brightening under an international anti-marine pollution treaty, the London Protocol, could be one effective route to setting standards for research and field experiments.
- But if MCB is deployed on a large scale, some experts say there is the potential for serious negative effects on the global climate system. These impacts could be especially severe if deployment is uncontrolled and lacks science-based governance.
Uttarakhand villagers thirst for water as tourism, temps & development rise
- An influx of tourists and new residents to Uttarakhand, driven by heat waves and work-from-home options, is straining local resources, particularly water.
- Nearly 12,000 natural springs reportedly have dried up in recent years, with 90% of Uttarakhand’s population depending on these vital water sources.
- Widespread construction for tourism disrupts aquifers and natural water percolation, exacerbating water scarcity and affecting water quality; water sources are further threatened by changing rainfall patterns and rising temperatures.
- Local residents, especially women and marginalized communities, face increased hardships in accessing water amid growing allegations of water diversion by hotels.
Climate change could return a stolen lake to Indigenous people, a century later
- Semá:th Xhotsa, or Sumas Lake, in Canada was the center of First Nations’ food system and culture, before European colonists drained it in 1924 to create farmland.
- Almost 100 years later, catastrophic flooding threatens to refill the lake and displace the farmers.
- First Nations people and university researchers have proposed restoring the lake ecosystem to adapt to climate change-driven flooding, and as a method of reparation, but the local government is pushing back.
Geoengineering gains momentum, but governance is lacking, critics say
- As the climate crisis advances, geoengineering — intentionally modifying Earth systems on a large scale to cool the planet or store additional carbon — is increasingly a hot topic. But an intense debate is raging as to how to govern research and deployment of these deeply contentious strategies.
- Stratospheric aerosol injection (SAI) — involving the release of sunlight-blocking particles such as sulfur dioxide into the lower atmosphere to block the sun’s rays — is at the forefront of a range of geoengineering technologies and approaches.
- Most SAI research to date involves modeling, while small-scale experimentation is foundering. SAI, though likely capable of cooling Earth’s climate, comes laden with governance challenges, myriad uncertainties and knock-on effects to the climate, ecosystems and human health.
- Projected deployment within a decade or two is cause for concern, say experts who warn that policy guidance and regulatory mechanisms at the national and international levels are now patchy at best, leaving huge gaps in oversight, transparency and monitoring of field research and potential deployment.
Biomass power grows in Japan despite new understanding of climate risks
- New biomass power plants continue to come online in Japan, requiring an ever-greater quantity of imported fuel. The government’s feed-in tariff scheme, which has been tweaked but not canceled, incentivized these projects.
- Although understanding of forest biomass’s negative environmental and climate impacts is growing in Japan, policy advocates say operators of existing biomass power plants need to pay back construction bank loans, and the government’s refusal to admit its mistake is keeping biomass plants running.
- A major biomass fuel type is wood pellets, which in Japan is presently primarily sourced from plantation forests in Vietnam and primary forests in British Columbia, Canada. While BC ecologists have spoken out against wood pellets, and found allies in Vietnam, the biomass issue has proved challenging for Japan’s forest advocates.
- Though historically a small source of wood pellets for Japan, the growing popularity in Indonesia of pellets for both export and domestic use risks tropical forests there being cleared to make way for biomass energy plantations, NGOs warn.
Don’t even study it: Geoengineering research hits societal roadblocks
- As climate change accelerates, some scientists are calling for more field research into solar geoengineering concepts. However, these ideas are running into opposition from other researchers, some governments and the public.
- A series of recent setbacks has put solar geoengineering research on the back foot, attempting to figure out a way to navigate the opposition.
- Proponents of field research say it would help humanity better understand the potential and problems with solar geoengineering, while opponents argue that there are too many risks and it could take our eye off the ball: cutting carbon emissions.
- The debate has spilled into the international arena, pitting nations that support greater research against those that would like to see a solar geoengineering non-use agreement.
Biochar could play big role in Bhutan’s carbon storage — but it’s news to farmers
- A new study shows that Bhutan has the potential to sequester 68% of its greenhouse gas emissions through biochar, a carbon-rich material made from organic waste that is used to help plants grow.
- The research shows that using crop residue as mulch and biochar can significantly increase yields; however, many farmers in Bhutan do not know about biochar nor do they have access to the raw materials, such as rice husks, necessary for its production.
- While many studies note biochar’s potential for mitigating climate change, some research shows that too much biochar under certain conditions can harm soil, soil organisms and water availability and can cause soil erosion.
As New England forests are razed for solar power, experts urge smarter siting
Every year across a handful of New England states and elsewhere in the U.S., developers cut forests to build utility-scale solar energy projects. Journalist and author Judith Schwartz lives near a forest in the otherwise environmentally progressive state of Vermont, where a company plans to install an 85-acre (34-hectare) solar power project and export the […]
Sun block: The promise and peril of solar geoengineering
- Recent research and interest, especially from the U.S. government, has pushed a solar geoengineering idea known as SAI, or stratospheric aerosol injection, to the top of lists of potential ideas to cool the planet. SAI would use fleets of high-flying aircraft to disperse sunlight-reflecting particles, including sulfates, into the stratosphere.
- As climate change worsens and carbon emissions continue to rise, researchers say we must be ready with other potential tools to stave off total catastrophe, such as the disintegration of the West Antarctic Ice Sheet with sea-level rise that would drown coastal cities.
- But critics say any geoengineering is too unpredictable and could allow governments to lower their ambitions on cutting emissions. They also argue that there’s no global governance policy to implement geoengineering justly.
- As debate intensifies, however, some feel it’s only a matter of time, given the current and projected trajectory of warming, until the world seriously considers geoengineering deployment.
Traditional foods have the potential to help Kashmir communities adapt to climate change: study
- A new study documented an array of wild edible plant species that four ethnic communities in the Kashmiri Himalayas traditionally depend on for food, medicinal use and to earn a living.
- Although the authors say the wild food sources show promise to alleviate food scarcity a and adapt to climate change, threats persist from over-extraction, changing climate, and traditional knowledge loss.
- Local food advocates are urging communities to cultivate and eat wild edible plant species to conserve traditional knowledge of their rich array.
Women in Sierra Leone unite after devastating floods
FREETOWN, Sierra Leone – In this episode of Mongabay Sessions, Romi Castagnino, Mongabay’s associate video producer, interviews documentary director Ibrahim S. Miles Kamara about his impactful film, Freetown Floodfighters: Women’s Resilience on the Frontline. This documentary highlights the efforts of community groups led by women to build resilience against climate change-induced floods in Freetown, Sierra […]
Can iron fertilization of the oceans help solve the climate crisis? (commentary)
- In response to climate change, several carbon dioxide removal approaches involving the marine environment are being studied, with ocean iron fertilization being among those with the greatest potential, according to the U.S. National Academies of Sciences.
- The introduction of iron into ocean regions that are iron-limited stimulates the growth of phytoplankton, which play a pivotal role in carbon sequestration, and while critics have long pointed out that such fertilization could cause wide ranging ecological consequences, a number of researchers are pursuing it with new energy.
- “It is important to conduct research and hold public deliberations to explore if iron fertilization could be effectively and safely done, and whether coastal communities and rights holders might actually want it,” a new op-ed argues.

‘Non-market’ solutions to deforestation need more support, advocates say
- In a report released May 29, three environmental groups called for a shift away from carbon markets and toward “non-market” solutions to deforestation.
- The Paris Agreement has a clause calling for such solutions, which the groups said could include financing for Indigenous groups, payment for ecosystem services, and debt relief.
- The report criticized carbon markets, saying incentives for brokers and project developers are misaligned with global environmental priorities.
Marshallese worries span decades — first nuclear tests, now sea-level rise
- The Marshall Islands were the site of numerous U.S. nuclear tests in the 1950s that displaced communities and altered their way of life.
- Locals across the islands and atolls are now at risk of evacuation and losing more of their ties to the land if sea-level rise continues at its current rate.
- For many Marshallese elders, their connection to the land is deeply rooted in their mind, body and soul: It is an integral part of their identity and culture.
- Elders talk about their concerns for the future and explain their intimate connection to their land.
Cutting forests for solar energy ‘misses the plot’ on climate action (commentary)
- In many places, solar power projects are being sited on natural forestlands, even in America’s greenest state, Vermont. This ignores the fact that natural forests are key climate solutions, and also studies which indicate solar projects are best sited in abandoned industrial site, above parking lots, and on warehouse roofs.
- In the latest example, an industrial solar project is proposed to replace a tract of forest in Shaftsbury, in the southwestern corner of the Green Mountain State, despite community opposition.
- “Because climate change has been framed as an energy problem that can be solved with solar panels, well-meaning legislators have crafted incentives that [are] exploited by out-of-state investment firms like the one holding an axe over our trees,” a new op-ed explains.

Are carbon credits another resource-for-cash grab? Interview with Alondra Cerdes Morales & Samuel Nguiffo
- Indigenous and traditional communities around the world are increasingly being recognized for their stewardship of forests.
- That’s led to their lands being seen as prime targets for carbon credit projects, the idea being that the carbon sequestered here can be sold to offset emissions elsewhere.
- While some Indigenous communities have welcomed these projects and the funds they bring in, others say they’re just another example of the monetization of natural resources that’s driving the climate crisis in the first place.
- Mongabay interviewed two leading Indigenous voices on both sides of the debate, who say the issue is a deeply nuanced one that carries implications for Indigenous land rights, culture and sustainability.
Report ranks 60+ ideas, including geoengineering, to save the Arctic
- Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
- A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
- The report ranked tried and true measures, like restoring peatlands, the highest, but some geoengineering ideas, such as solar geoengineering, also ranked high.
- Researchers say, however, that while geoengineering ideas may be worth studying, the goal right now must be to aggressively cut emissions. Some also fear that geoengineering will become a costly distraction, diverting attention from the need for fossil fuel companies to cut production, and for decarbonization of the economy.
‘Weather whiplash’ cycles of floods & droughts imperil Nigerian farming
- Farmers in Nigeria — and other regions, particularly in sub-Saharan Africa — are suffering huge losses due to extreme weather shifts in quick succession, a phenomenon that researchers refer to as “weather whiplash.”
- Research shows a connection between poverty and weather whiplash, and farmers in poorer regions are five times more exposed to drought-downpour cycles than people in wealthier regions.
- In April, the independent SciLine service for journalists hosted a webinar with agricultural scientists who discussed these extreme weather cycles, the impacts of climate change on agriculture in different regions and the need for homegrown approaches to support agriculture resilience.
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.
From polling stations to weather stations, the heat is on in India (commentary)
- Parts of India are facing a heatwave, for which the heat in the state of Kerala is a curtain raiser. Kerala experienced its first recorded heatwave amid the ongoing election campaign.
- Heatwaves, droughts and floods do not distinguish along political lines. If the destruction is across board, the mitigating action also has to be across political lines, writes Mongabay-India’s Managing Editor, S. Gopikrishna Warrier, in this commentary.
- Climate change poses economic, social and political challenges, influencing election discourse and policy agendas.

UK’s Drax targets California forests for two major wood pellet plants
- Golden State Natural Resources (GSNR), a California state-funded nonprofit focused on rural economic development, along with the U.K.’s Drax, a global maker of biomass for energy, have signed an agreement to move ahead on a California project to build two of the biggest wood pellet mills in the United States.
- The mills, if approved by the state, would produce 1 million tons of pellets for export annually to Japan and South Korea, where they would be burned in converted coal power plants. The pellet mills would represent a major expansion of U.S. biomass production outside the U.S. Southeast, where most pellet making has been centered.
- GSNR promotes the pellet mills as providing jobs, preventing wildfires and reducing carbon emissions. California forest advocates say that cutting trees to make pellets —partly within eight national forests — will achieve none of those goals.
- Opponents note that the U.S. pellet industry is highly automated and offers few jobs, while the mills pollute rural communities. Clear-cutting trees, which is largely the model U.S. biomass firms use, does little to prevent fires and reduces carbon storage. Pellet burning also produces more emissions than coal per unit of energy produced.
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.
Multilateral development banks must prioritize clean & community-led energy projects (commentary)
- Multilateral Development Banks (MDBs), governments, and corporations across 160 countries consider or approve more than one investment per day in the energy sector.
- Despite commitments to tackle the climate crisis, many of these investments support the fossil fuel industry, while others invest in false clean energy solutions like hydropower which often cause harm to local communities.
- “To achieve a just energy transition, MDBs and governments must prioritize sustainable renewable energy models that empower communities and ensure inclusive energy access,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
U.S. East Coast adopts ‘living shorelines’ approach to keep rising seas at bay
- Along the U.S. East Coast, communities are grappling with the dual destructive forces of rising sea levels and stronger storms pushed by climate change, resulting in effects ranging from ‘ghost forests’ of saltwater-killed coastal trees in the Carolinas, to inundations of New York City’s subway system.
- While the usual response has been to build higher seawalls and other concrete or rock structures, a natural approach that aims to protect coastal areas with natural assets that also create habitat and are generally cheaper and less carbon intensive — ‘living shorelines’ — is increasingly taking hold.
- State agencies and landowners alike are shoring up the shore with innovative combinations of locally sourced logs, rocks and native plants and shrubs to protect homes, dunes and beaches.
- In Maine, where a trio of powerful winter storms recently pummeled the coast, living shorelines designers are in growing demand.
Consent and costs are key questions on extraction of ‘energy transition’ minerals
- The many environmental, social, and health impacts of extracting minerals that power renewable energy, mobile phones and electric vehicles need more debate and detailed media coverage, an Indigenous rights activist and journalist say on the podcast.
- Mongabay speaks with Galina Angarova, Indigenous executive director of the SIRGE Coalition, and environmental journalist Ian Morse about critical questions to ask about the demand for certain minerals and who benefits from their extraction.
- Research indicates as much as 54% of all transition minerals are on or near Indigenous land, however, no nation has properly implemented the protocols of Free Prior and Informed Consent (FPIC), a framework that’s key to ensuring that local communities are aware of, benefit from – and especially are not harmed by – such activities.
- The risk of global supply chain disruptions due to the concentration of minerals in relatively few countries, or the potential formation of cartels restricting their supply, adds further complexity to the situation, the two podcast guests say.
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.
Circular solutions vital to curb enviro harm from cement and concrete
- Concrete is ubiquitous in the modern world, but building cities, roads and other infrastructure and more comes with an environmental cost. Cement and concrete production is responsible for significant pollution, human health impacts and vast amounts of climate-fueling emissions.
- Manufacturing cement is particularly problematic as the chemical process used to make it produces nearly 8% of global carbon emissions. Experts also underline that demand for the mined and quarried aggregate materials used to make concrete, such as sand, is responsible for biodiversity and ecosystem harm.
- Demand for cement and concrete is set to grow, especially in developing countries to improve infrastructure and living standards. Experts say that solutions reigning in the sector’s environmental footprint are vital, especially curbing greenhouse gas emissions that could absorb a major chunk of our remaining carbon budget.
- Solutions to address these challenges include a suite of technological advances, material changes, improved resource efficiency, and circular economy approaches. Some specifics: electrifying cement kilns, low-carbon concrete, carbon capture, and bio-architecture utilizing natural building materials.
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.
Panama delays promised relocation of sinking island community
- The government of Panama continues to delay the process of relocating almost 1,300 Indigenous Guna inhabitants from an island experiencing rising sea levels due to climate change.
- The lack of space on the tiny Caribbean island of Gardi Sugdub means there’s no room to relocate, and a new site on the mainland for the community has been in the works since 2019.
- But plans for the relocation have been repeatedly delayed due to administrative issues, previous COVID-19 restrictions and poor budgeting, leaving residents skeptical that government promises will be upheld.
- Members of this fishing community have also expressed concern about the relocation site, which is a 30-minute walk from the coast, and about the design of the new homes, for which the government didn’t seek Guna input.
Rainwater reserves a tenuous lifeline for Sumatran community amid punishing dry season
- Kuala Selat village lies on the coast of Indragiri Hilir district on the Indonesian island of Sumatra.
- In the first half of the year, residents of the village arrange buckets and drums to collect rainwater to meet their daily needs.
- They will then stockpile water to last through the dry months from June-September, but a longer dry spell has led to an acute shortage of water.
- Residents say they believe the water crisis in the village was linked to bouts of diarrhea, and that many fled the village during an outbreak.
Enviva bankruptcy fallout ripples through biomass industry, U.S. and EU
- In March, Enviva, the world’s largest woody biomass producer for industrial energy, declared bankruptcy. That cataclysmic collapse triggered a rush of political and economic maneuvering in the U.S. (a key wood pellet producing nation), and in Europe (a primary industrial biomass energy user in converted coal plants).
- While Enviva publicly claims it will survive the bankruptcy, a whistleblower in touch with sources inside the company says it will continue failing to meet its wood pellet contract obligations, and that its production facilities — plagued by chronic systemic manufacturing problems — will continue underperforming.
- Enviva and the forestry industry appear now to be lobbying the Biden administration, hoping to tap into millions in renewable energy credits under the Inflation Reduction Act — a move environmentalists are resisting. In March, federal officials made a fact-finding trip to an Enviva facility and local communities who say the firm is a major polluter.
- Meanwhile, some EU nations are scrambling to find new sources of wood pellets to meet their sustainable energy pledges under the Paris agreement. The UK’s Drax, an Enviva pellet user (and also a major pellet producer), is positioning itself to greatly increase its pellet production in the U.S. South and maybe benefit from IRA subsidies.
E-bikes could cut smog, energy use and congestion globally — but will they?
- The global market for e-bikes is surging. These bicycles, usually equipped with pedals and an electric motor assist, are popular with consumers and commuters and are becoming part of local business delivery systems. The trend could significantly reduce particulate pollution and smog, as well as cut carbon emissions in the transportation sector.
- But there are barriers. No international manufacturing standard yet exists for e-bikes. Also, transportation and charging infrastructure doesn’t adequately accommodate e-bikes, especially in the developing world where electric bicycles have the potential to replace super-polluting gas-powered scooters, motorcycles and pedicabs.
- Poorly made or improperly maintained e-bike batteries have developed a reputation for sometimes causing fires, exploding and even killing people, which has caused hesitation among consumers. While this safety problem is a real one, manufacturers and enthusiasts say the e-bike industry can effectively deal with it.
- Some governments are offering subsidies and tax incentives to e-bike buyers, while some companies are offering deals allowing customers to trade in gas two-wheelers for e-bikes. As sales and use grow, updated bike lane construction and safety rules setting permissible e-bike horsepower, speed and size will be required.
This year’s ranking of EV carmakers from most to least ‘clean’: Report
- A new scorecard by a coalition of labor and environmental civil society organizations ranked the top 18 automakers against 80 measures of what a clean car supply chain would look like.
- While car companies are increasingly embracing electric vehicles, a lack of tailpipe emissions is not enough for a car to be considered truly ‘clean,’ the authors say.
- From the steel, aluminum, tires, batteries and people affected along the supply chain, the mining and manufacturing of these metal-dense machines puts heavy burdens on landscapes, Indigenous peoples and workers.
- Ford and Mercedes-Benz lead the automotive world in working to clean up their supply chains, while Tesla jumped to third from last year’s ninth spot. East Asian firms fell behind as they lacked policies to address decarbonization in the production of steel and aluminum.
We need rapid response support for Indigenous peoples in the face of growing extreme weather events (commentary)
- Climate change can sometimes feel distant and intangible, but the increasingly frequent extreme weather events in tropical forest regions like the Amazon and Congo Basin are already having very real-world impacts on Indigenous and other local communities in these areas.
- While Indigenous and grassroots organizations are often the first responders and are best placed to know the needs of their communities, they face huge challenges in accessing heavily bureaucratic disaster response funding.
- This is why we are calling for the establishment of a dedicated fit-for-purpose rapid response fund for them to be able to respond and recover from such events.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
‘Another catastrophe’: Flooding destroys Indigenous agroforestry projects in Peru’s Amazon
- Heavy rains likely caused by El Niño began flooding Peru’s Ene River at the beginning of March, with waters reaching around 2 feet high and spreading across 5,000 hectares (12,355 acres) of land occupied by around 300 Indigenous Asháninka families.
- Families in five Asháninka communities lost their homes as well as years of work on successful and sustainable agroforestry projects for cacao, coffee and timber, among other products.
- The flood waters have only recently receded, so a long-term or even mid-term plan for recovering their agroforestry projects hasn’t been developed yet.
- The Asháninka have faced many other setbacks over the years, from drug trafficking groups to unsustainable development projects, but have often overcome them to defend their territory. This flood marks the latest setback.
‘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.
Critics fear catastrophic energy crisis as AI is outsourced to Latin America
- AI use is surging astronomically around the globe, requiring vastly more energy to make AI-friendly semiconductor chips and causing a gigantic explosion in data center construction. So large and rapid is this expansion that Sam Altman, the boss of OpenAI, has warned that AI is driving humanity toward a “catastrophic energy crisis.”
- Altman’s solution is an audacious plan to spend up to $7 trillion to produce energy from nuclear fusion. But even if this investment, the biggest in all of history, occurred, its impact wouldn’t be felt until mid-century, and do little to end the energy and water crises triggered by AI manufacture and use, while having huge mining and toxic waste impacts.
- Data centers are mushrooming worldwide to meet AI demand, but particularly in Latin America, seen as strategically located by Big Tech. One of the largest data center hubs is in Querétaro, a Mexican state with high risk of intensifying climate change-induced drought. Farmers are already protesting their risk of losing water access.
- As Latin American protests rise over the environmental and social harm done by AI, activists and academics are calling for a halt to government rubber-stamping of approvals for new data centers, for a full assessment of AI life-cycle impacts, and for new regulations to curb the growing social harm caused by AI.
UN probes controversial forest carbon agreement in Malaysian Borneo
- The government of Sabah state in Malaysian Borneo will continue to move forward with an opaque nature conservation agreement despite concerns raised by the United Nations.
- In a letter, the U.N. calls in question the transparency of the agreement and the state’s approach to the human rights law principle of free, prior and informed consent.
- The agreement was signed by state officials and a representative of a Singaporean company in 2021. Shortly after news of the deal became public, some Indigenous groups in the state said they hadn’t been consulted or informed about the deal covering 2 million hectares (4.9 million acres) of the state’s forests.
- The U.N. letter was written by a group of “special procedures experts” with mandates established by the U.N. Human Rights Council, including the special rapporteurs on the rights of Indigenous peoples, on human rights and the environment, and on the right to development.
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.
Global conference to accelerate nature-based solutions: Q&A with Self Help Africa’s Patricia Wall
- This week, more than 150 conservation and community organizations, experts and policymakers are gathering in Zambia for the Accelerating Nature-based Solutions conference.
- Discussions will dive deep into critical issues and concerns regarding nature-based solutions and the roles of agroforestry, farmer-managed natural regeneration and wildlife conservation in NbS.
- The conference will also address the issue of carbon offsetting and greenhouse gas emissions, and the need to safeguard the rights of local communities or Indigenous communities when implementing nature-based solutions.
Study on Brazilian heat wave deaths shows gender & racial disparities
- A new study estimates that the deaths of nearly 50,000 people in Brazil in recent decades could be attributed to the occurrence of heat waves, and it points out that these extreme events have become increasingly frequent.
- The paper reveals that Blacks, Browns, females, older adults and those with lower educational levels are the most affected population subgroups, suggesting that the impacts of heat waves are felt unevenly, thus exposing socioeconomic inequalities.
- The researchers analyzed data from 14 metropolitan regions with a population of 74 million people, representing nearly one-third of Brazil’s population.
- This research is important because it joins others in analyzing racial and gender dimensions of the populations most vulnerable to extreme events, the scientific coordinator at Iyaleta Research Association says.
Pollution poses big risks to global clean water supplies, study shows
- Nitrogen pollution could intensify global water scarcity threefold by 2050, scientists warn in a recently published paper. In addition, “newly emerging pollutants,” such as microplastics, heavy metals, pathogens and pharmaceuticals, emitted into waterways could cause “severe water degradation in the future.”
- Modeling the escalating impact of nitrogen pollution on water quality, the scientists found that more than 3,000 river basins globally are at risk of water scarcity by 2050 in one future scenario. That finding comes along with concern that climate change could exacerbate water quality decline and increased scarcity.
- Nitrogen pollution and water contamination by heavy metals and pathogens have serious known public health consequences, while health impacts from microplastics and pharmaceuticals need far more research.
- The researchers suggest solutions that include curbing nitrogen pollution through better fertilizer management practices and improved wastewater treatment.
In climate-related flooding, a Ugandan river turns poisonous
- Uganda’s Nyamwamba river, in the Rwenzori Mountains, has begun to flood catastrophically in recent years, partly due to climate change.
- Along the river are copper tailings pools from an old Canadian mining operation, which are becoming increasingly eroded by the flooding.
- According to a series of studies, these tailings have been washing into the water supply and soil of the Nyamwamba River Basin, contaminating human tissue, food and water with deadly heavy metals.
- Cancer rates are higher than normal near the tailings pools, and scientists fear that as the flooding continues to worsen, so will the health crisis.
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.
As lightning strike fatalities increase, Bangladesh still has no reliable preventive measures
- Between 2011 and 2020, lightning strikes claimed the lives of 2,164 people, or nearly four people every week, in Bangladesh, according to the country’s disaster management department. However, a Bangladeshi NGO reports at least a thousand more lightning related fatalities between 2010 and 2021.
- Researchers linked the increased frequency of lightning with climate change; as for the increased death toll, they blamed the government’s inefficient protection measures, including the lack of tall trees.
- To reduce the number of fatalities, the government has started working on long-term solutions, such as installing lightning arresters and growing palm trees. Nevertheless, a significant sum of money is being squandered and nothing functions as expected, say experts.
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.”
Climate change brings a river’s wrath down on western Uganda
- Since the 1960s, Uganda’s climate has warmed by an average of 1.3°C (2.3°F).
- The warming is partly responsible for an increasing number of catastrophic floods on the Nyamwamba River, in western Uganda’s Rwenzori Mountains.
- In 2020 alone, 173,000 people were affected by flooding in Kasese district, when 25,000 houses were destroyed.
- Many of those rendered homeless by the floods continue to languish in temporary housing camps four years on.
U.S. natural gas expansion would surrender world to fatal warming, experts say
- The United States is planning a major expansion of its export infrastructure for liquified natural gas (LNG), a fossil fuel mostly containing methane. Public outcry in the U.S. over the risk to the global climate forced U.S. President Joe Biden to pause the LNG permitting process for reconsideration in January.
- However, the U.S. continues investing billions in new LNG infrastructure abroad. Scientists and climate activists around the globe are warning that LNG expansion renders U.S. climate commitments unreachable, locks in fossil fuel emissions for decades and could trigger catastrophic warming.
- LNG emits more than coal when exported due to massive leaks of methane into the atmosphere during oceanic transport, a preprint study has found. Another report estimates that emissions from planned U.S. LNG exports, if all 12 facilities are approved, would total 10% of the world’s current greenhouse gas emissions.
- Climate impacts around the world would be severe, scientists say. Drought in Europe, for example, is already leading to higher food and energy prices, creating conditions for poverty even in developed nations, while a tipping point in the Amazon Rainforest could lead to mass deaths due to extreme heat and humidity.
Locals at the mouth of the Amazon River get a salty taste of climate change
- Ocean rise and changes in the Amazon River are ruining the way of life in an archipelago close to where the Amazon River runs into the Atlantic.
- In Bailique, locals are experiencing longer periods of salty water, a natural phenomenon that is becoming more usual due to climate change.
- Açaí berries, the prime economic drive of the community, are becoming saltier, and palm trees are being eaten by the erosion caused by changes in the Amazon River’s flow.
- Part of the population has already left the region, as others struggle to adapt to the new landscape.
What principles should define natural climate solutions? A new study has some answers
- The increased popularity of natural climate solutions (NCS), which aim to protect and restore natural ecosystems to address climate change, has resulted in misunderstandings and confusion around what constitutes such a solution.
- Researchers distill five foundational principles of natural climate solutions and 15 operational principles to guide their implementation; among others, the principles include equity, emphasizing the need for practitioners to respect human rights and self-determination of Indigenous peoples.
- Researchers argue that natural climate solutions that adhere to these principles are durable and effective in tackling climate change in the long run, resulting in widespread adoption.
- While experts agree that the outlined principles reduce confusion and spur climate action, they call for tightening the definitions of some principles to strengthen the proposed framework.
Freeze on Russian collaboration disrupts urgently needed permafrost data flow
- Accelerating Arctic warming threatens to thaw more and more carbon-rich permafrost and release vast amounts of greenhouse gases into the Earth’s atmosphere, but scientists don’t know when such a tipping point event might occur.
- The potential for large and abrupt permafrost emissions adds urgency to better understanding the factors that could turn permafrost from a carbon sink into a carbon source.
- However, more than half of all Arctic permafrost lies under Russian soil, and a two-year freeze on collaborations between Russian scientists and the international scientific community — prompted by the Russian invasion of Ukraine on Feb. 24, 2022 — is disrupting data flows and hamstringing the polar research community.
- Despite an uncertain geopolitical landscape, scientists are determined to close the data gap with work-arounds such as pivoting to “proxy” field sites, ramping up remote sensing with AI, and mining archived data for new insights. But reintegrating Russian research with other Arctic research is a priority of the scientific community.
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.
As climate disasters claim their children, Bangladeshi mothers seek safety in bigger families
- Climate change is exacerbating child mortality in flood-prone areas of Bangladesh, prompting mothers to have larger families as a response to the fear of losing children to disasters.
- Studies indicate an 8% surge in infant mortality risk in flood-prone regions, resulting in more than 150,000 lives lost between 1988 and 2017.
- While Bangladesh has seen improvements in disaster management, reduced cyclone deaths, and progress in health for mothers and children, climate change poses new threats, especially to vulnerable coastal communities lacking adequate protection.
- A National Adaptation Plan offers solutions such as water conservation and livelihood opportunities, but challenges like funding, coordination and transparency need attention for effective implementation, experts say.
The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
- Every species of animal and plant that lives or breeds in the Arctic is experiencing dramatic change. As the polar region warms, species endure extreme weather, shrinking and altered habitat, decreased food availability, and competition from invading southern species.
- A wide array of Arctic organisms that rely on sea ice to feed or breed during some or all of their life cycles are threatened by melt: Over the past 40 years, the Arctic Ocean has lost about 75% of its sea ice volume, as measured at the end of the summer melt season. This translates into a loss of sea ice extent and thickness by half on average.
- Researchers note that the rate of change is accelerating at sea and on land. While species can adapt over time, Arctic ecosystem alterations are too rapid for many animals to adapt, making it difficult to guess which species will prevail, which will perish, and where.
- The only thing that could limit future extinctions, researchers say, is to quickly stop burning fossil fuels, the main driver of climate change.
Fashioning a circular future for traditional and alternative leather
- Crafting leather from animal hides is an age-old industry, but its production today continues to mostly follow a linear model often mired in a range of environmental problems, including pollution, the creation of huge amounts of waste, high water use, and climate change-causing emissions.
- Applying cleaner and circular economy-based solutions to the leather industry is needed to change this paradigm and make the supply chain more environmentally friendly, say experts. Some companies are heading down this path, but efforts to roll out such solutions globally to all producer nations face a host of barriers.
- Some companies see the future of a sustainable leather industry in synthetic and biobased alternatives, using a smorgasbord of waste agricultural materials and more in the place of animal hides and plastics. But these alternatives, too, come with their own sustainability challenges or questions of scalability.
- Above all, experts say, achieving viable long-term circular solutions for the leather industry will require a diverse range of sustainable supply chain and production innovations, including the use of alternative materials.
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.
Ocean heating breaks record, again, with disastrous outcomes for the planet
- New research shows that ocean temperatures are hotter than ever in the modern era due to human-driven global warming.
- High ocean temperatures are placing a strain on marine life and biological processes while also increasing extreme weather events on land.
- The world is also seeing an escalation in the frequency and intensity of marine heat waves, events in which sea temperatures exceed a certain threshold for five days or more.
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.
Markets and forests: 7 takeaways from our series on the forest carbon trade
This is the wrap-up article for our five-part series on forest carbon credits and the voluntary market. Read Part One, Part Two, Part Three, Part Four and Part Five. Mongabay recently published a five-part series on the carbon trade and its use as a tool to address climate change. The exchange of carbon credits, typically […]
The future of forest carbon credits and voluntary markets
- Observers predicted that 2023 would be a “make-or-break” year for voluntary carbon markets and “an inflection point” for their role in addressing climate change and global deforestation.
- Amid criticisms around carbon accounting, carbon neutrality claims, and issues with forest communities, governance bodies say they’ve worked to increase consistency and “integrity” for the voluntary carbon market and specifically the forest conservation strategy known as REDD+.
- Concerns remain from a variety of observers, including those who say the focus of credit-buying companies should be on eliminating their carbon emissions from across their entire suite of operations.
- But proponents of markets say that while decarbonizing is absolutely necessary to minimize the rise in global temperatures, the carbon trade allows for the mitigation of pesky residual emissions that it’s either impossible or too expensive to get rid of at this point.
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.
Con Chim: A window into Vietnam’s past and future beyond rice fields
CON CHIM, Vietnam —In response to escalating climate concerns, Vietnam is rethinking its approach to agriculture by reducing rice farming and adopting nature-based practices. Con Chim, once an overlooked region, is now emerging as a beacon of sustainable farming. Watch this video to learn more about how this transformation is setting a new standard for […]
Leveraging the hypothetical: The uncertain world of carbon credit calculations
- Criticisms of the voluntary carbon trade and forest conservation strategies like REDD+ have centered largely on the carbon accounting methods used to calculate credits.
- Each credit traded on voluntary markets is supposed to represent the reduction, avoidance or removal of 1 metric ton of carbon dioxide from the atmosphere.
- But recent science has raised questions about how REDD+ and other types of project figure out the number of tons of emissions saved.
- The process relies on establishing a baseline rate of deforestation against which a project’s emissions-reducing or -removing success is measured. But critics say the process can be faulty and that the conflicts of interest of the parties involved in setting the baseline have not been addressed until recently.
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.
‘Cowboys’ and intermediaries thrive in Wild West of the carbon market
- A host of different players have crowded into the voluntary carbon trade as its value has grown.
- Motivated by the potential for profit, a concern for climate change or some combination of the two, these companies and organizations link the credits generated by projects, such as those that fit in the forest conservation scheme known as REDD+, with buyers, often companies and individuals in the Global North looking to compensate for their climate impacts.
- Some groups say they help shoulder the burden of tasks like marketing so that the communities and project staff on the ground can focus on the “change-making work.”
- But others, sometimes called “carbon cowboys,” seem interested in the money to be made from trading carbon. Some have faced allegations that they don’t bring the necessary expertise to their work, or that they don’t adequately inform local communities about the intended projects and the potential pitfalls.
Do carbon credits really help communities that keep forests standing?
- Communities play a critical role in REDD+, a forest conservation strategy that aims to reduce emissions that can be sold as credits to raise money for forest protection.
- REDD+ projects often include components for the benefit of the communities, such as a focus on alternative livelihoods and provision of health care and education.
- But reports that REDD+ communities have faced abuses and rights violations have emerged recently in connection with high-profile REDD+ projects.
- Several Indigenous-led organizations have voiced their support for REDD+ because, they say, it provides an avenue to fund their climate-related conservation work, while other groups say it’s not the answer.
Forest carbon credits and the voluntary market: A solution or a distraction?
- Voluntary carbon markets and forest carbon credits have faced widespread criticism that reached a zenith in 2023.
- Media reports detailed concerns about their dubious climate benefits, respect for communities and land rights, and their use by Global North companies to avoid the difficult task of decarbonizing their operations.
- Supporters of forest conservation strategies like REDD+ say that they can and should play a role, as healthy forests can absorb a significant amount of atmospheric carbon. They also say REDD+ brings much-needed funding to protect and restore forests, not only for their carbon, but because of the biodiversity and communities they support.
- As 2023 draws to a close, and with it the U.N. climate conference in Dubai (COP28), proponents of the voluntary carbon trade are working to increase the “integrity” of markets in ways they hope make them a viable tool to deal with climate change.
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.
As the world swims in plastic, some offer an answer: Ban the toxic two
- Anti-plastic campaigners have achieved limited initial success in passing bans based on the toxic health effects of some plastic types, especially those that contain known carcinogens and hormone-disrupting chemicals.
- Some activists say that two of the most toxic types of plastic, polystyrene and polyvinyl chloride (PVC) should be completely banned. But so far, bans of polystyrene in Zimbabwe, Scotland and elsewhere have focused only on certain products, such as takeout containers.
- PVC is used in medical devices and children’s products, despite its well-known toxicity. PVC and polystyrene are both used in consumer construction, where they can leach chemicals into water or home air, or release particles into the wider environment.
- The U.S. EPA is reviewing vinyl chloride, PVC’s main ingredient and a known carcinogen, but the outcome won’t be known for several years and may only affect U.S. production, not imported products made of PVC. More than 60 nations want a ban on “problematic plastics” by the global plastics treaty now being negotiated.
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.
In Brazil’s Caatinga, these families excel in farming productivity
UAUÁ, Bahia, Brazil — In northeastern Brazil, the innovative Agrocaatinga model is revolutionizing food security, income generation, and native vegetation preservation. This sustainable approach combines agroforestry with rainwater harvesting techniques, revitalizing previously degraded lands to produce over 50 different food types. Originating from the growing commercial demand for wild passion fruit, this model enables families […]
Reports allege abuses by Glencore in Peru and Colombia, and the banks funding them
- Mining giant Glencore continues to commit serious environmental and human rights violations in its mines in Peru and Colombia despite public promises to respect human rights and the environment, according to three news reports by advocacy organizations.
- The reports document cases of air and water pollution, extensive environmental damage, lack of consultation with communities, and restricting access to land.
- European banks and investors, including Groupe BPCE, HSBC, Abrdn and BNP Paribas, hold the largest investments in Glencore, pumping $44.2 billion into the company between 2016 and 2023.
- Glencore denies the allegations made against it and says it has continued to make progress on its climate targets and remains on track to meet its environmental and human rights commitments.
Marine conservation technology hub rises from old L.A. wharf (analysis)
- In 2014, the Port of Los Angeles gave a 50-year lease to an aging wharf called City Dock No. 1 to a project called AltaSea.
- AltaSea is a non-profit project founded in 2014 that in less than 10 years has become a leading ‘blue economy’ research hub focused on renewable ocean energy, sustainable aquaculture and other blue technologies.
- Hub tenants include marine renewable energy startups, sustainable aquaculture projects, a marine seed bank, a research effort aimed at decarbonizing oceanic shipping, and other projects.

COP28 ‘breakthrough’ elevates litigation as vital route to climate action
- In the past three decades, the United Nations has sponsored 28 annual climate summits. But that process has failed to provide a legally binding path to significant carbon emission reductions or to the phaseout of fossil fuels responsible for the climate crisis.
- The just concluded COP28 summit, held in Dubai and largely controlled by fossil fuel interests, has pledged “transitioning away from fossil fuels” but that deal is also voluntary. Now, with the world on track for catastrophic global warming, litigation is increasingly being used to force governments to regulate fossil fuels and enforce existing laws.
- Thousands of climate-related lawsuits are underway to reduce emissions, stop drilling or gain compensation for the Indigenous and traditional peoples who are the most vulnerable to climate impacts.
- But despite some court wins for the environment, the litigation process is slow and unlikely to achieve major results in time to staunch fast-moving warming. Even when lawyers do win climate suits, there is no guarantee governments or corporations will obey judicial decisions.
Earth on ‘devastating trajectory’ to global tipping points. But there’s hope.
- A new report on global tipping points warns of imminent serious disruptions in major Earth systems if global temperatures continue rising due to human-induced climate change.
- It suggests that current levels of warming will likely push five major Earth systems past their tipping points, and another three will follow if global temperatures exceed 1.5° Celsius (2.7° Fahrenheit) of warming above preindustrial levels.
- However, along with these dire warnings, the report also notes the launch of positive tipping points within society, such as the rollout of renewable energy technologies.
- Other reports also describe the urgency to enact positive change as humanity continues pumping carbon into the atmosphere, wreaking havoc on the environment.
Thailand tries nature-based water management to adapt to climate change
- With an economy largely underpinned by irrigated crops like rice, water is a crucial resource in Thailand. But as climate change exacerbates floods and droughts in the country, sustainable water management is an increasing challenge.
- Nature-based solutions that incorporate the natural processes of the country’s abundant rivers, floodplains and watershed forests are beginning to be trialed via various projects at large and small scales.
- A new report assesses the efficacy of two nature-based approaches to water management in Thailand, which represent a step away from the country’s typically top-down, hard-engineering approach and present several benefits to the environment and communities.
- However, environmental and societal tradeoffs, complex policy frameworks, and the need for greater understanding and expertise around the concept, design and implementation of nature-based approaches are barriers to their widespread implementation.
Any fossil fuel phase-out deal at COP28 must include global shipping (commentary)
- If ocean shipping were a country, it would be the sixth-largest carbon emitter, eclipsing Germany, so the International Maritime Organization recently set targets to reduce shipping’s 1 billion tons of annual emissions in order to reach zero by 2050.
- International shipping accounts for about 2.2% of all global greenhouse gas emissions, plus 40% of all cargo carried by these ships is oil, gas, and coal, making shippers a key cog in the global fossil fuel supply chain.
- “I call on the COP presidency [to] include all global polluters in any agreement on phasing out fossil fuels, even those far out at sea,” a new op-ed states.

Ecologists help migratory birds adapt to climate change
- Warmer and earlier spring seasons cause problems for migratory birds, who return to breeding sites after winter to find that most of their food is already gone.
- Researchers drove European pied flycatchers north from the Netherlands to Sweden, where spring arrives two weeks later and food supplies peak at the right time for newly hatched chicks.
- Birds born in Sweden flew back to the same northern sites on their own to breed, showing that scientists might be able to help some species adapt to climate change.
Climate loss & damage fund ‘the furthest thing imaginable from a success’
- The fifth and final meeting of the U.N. Transitional Committee to design a loss and damage fund ahead of COP28 climate summit concluded in Abu Dhabi last month without a mandate that wealthy, industrialized nations pay into it, sources say.
- Frequent Mongabay contributor and journalist Rachel Donald joins the Mongabay Newscast as co-host to speak with Brandon Wu, director of policy and campaigns at ActionAid USA, to unpack this most recent negotiation.
- In addition to leaving out a provision for contributions from wealthy nations, the fund will be housed in the World Bank, a global lending institution that continues to fund coal projects and has been linked to human rights abuses.
- The text of the fund will move to the 2023 United Nations Climate Change Conference (COP28) in Dubai next month, where it will be considered by member countries.
Kenyan pastoralists fight for a future adapted to climate change (commentary)
- Pastoralism provides much of the milk and protein consumed in Kenya, but it faces a perilous future especially from climate change but also a lack of infrastructure and land rights.
- Recent droughts have exacerbated the challenges, leading to conflict between pastoralist communities struggling to find enough forage and water for livestock.
- Fresh ideas and new programs are arising to help ease the situation in areas of northern Kenya, from where this dispatch originates.

How Indigenous peoples and local communities can make the voluntary carbon market work for them (commentary)
- The voluntary carbon market has the potential to address $4.1 trillion in nature financing gap by 2050 and support Indigenous peoples and local communities — when done right, argue a cohort of Indigenous leaders in a new commentary.
- The voluntary carbon market can work for and support Indigenous peoples and local communities (IPs and LCs), and them for it, but these communities have not been adequately engaged or consulted to participate in this carbon market.
- The Indigenous leaders announce the new IPs and LCs Voluntary Carbon Market Engagement Forum that is taking shape and will try to address these IPs and LCs’ priorities. The Forum is now coordinating open calls for Governing Board members and Forum partners.

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.
Carbon counting without the guesswork: Q&A with FCL proponent Jerry Toth
- REDD+ projects aim to incentivize efforts that maintain standing forests, rather than cutting them down, by providing payments based on the carbon emissions kept out of the atmosphere.
- But REDD+, which is short for “reducing deforestation and forest degradation in developing countries,” has been widely criticized lately, in part because skeptics say that the accounting methods are open to manipulation by developers aiming to sell more credits — credits that many not represent a verifiable climate benefit.
- One alternative is the forest carbon ledger (FCL). FCL seeks to value the total amount of carbon in a forest and would provide payments based on how well that storage is maintained over time.
- Mongabay spoke with Jerry Toth, co-founder of a conservation group working to protect and restore the last remaining remnants of the Pacific Forest of Ecuador called the Third Millennium Alliance (TMA). Toth said FCL may provide a more robust alternative to REDD+ carbon accounting.
Glencore’s coal expansion plans face shareholder and Indigenous opposition
- Swiss-based mining giant Glencore says it plans to challenge the proposed listing of a heritage site, the Ravensworth Homestead, that could deter the planned expansion of its Glendell coal mine.
- Glencore, the largest coal producer in Australia, faces criticism from shareholders for its lack of transparency on how it plans to meet its climate targets, especially in light of proposed thermal coal mine expansions in the country.
- Listing the homestead, which is a culturally significant site for the Indigenous Wonnarua people, is now being reconsidered by heritage officials after a process that sources say has dragged on.
- The Glendell mine is one of several that could increase their emissions under a loophole in the government’s revised “safeguard mechanism” that’s intended to bind the mining sector to a reduction in emissions.
Circular economy poised to go beyond outdated oil, gas and coal, experts say
- The exploitation of oil, gas and coal is now destabilizing all nine planetary boundaries and driving a triple crisis of climate change, biodiversity loss and pollution. The solution, experts say, is to move from a hydrocarbon-based linear economy to a diversified circular economy. This is Part 3 of a three-part miniseries.
- To step back from dangerous environmental thresholds, humanity needs to cut its use of fossil fuels, petroleum-based synthetic fertilizers and petrochemicals (especially plastics), with many analysts unequivocal about the unlikelihood of utilizing oil, gas and coal resources to implement a global circular economy.
- To achieve a circular economy, fossil fuels need to be phased out and alternative energy sources put in place. Bio-fertilizers need to be adopted and scaled up, and nitrogen fertilizers must be managed better to prevent overuse. Plastic production needs to be curbed, with a ban of single-use plastics as a start.
- Unfortunately, the world isn’t on target to achieve any of these goals soon, with surging oil and natural gas production by the U.S., Saudi Arabia and Russia expected to push the planet past the maximum 2° C (3.6° F) temperature increase agreed to in the 2015 Paris Accord — putting Earth at risk of climate catastrophe.
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.
Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.
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.
Can carbon markets solve Africa’s climate finance woes?
- The African Carbon Markets Initiative, a consortium of Global North donors, corporate representatives, conservation groups and energy lobbyists, is pushing to expand carbon markets on the continent.
- The effort has gained the vocal support of Kenyan President William Ruto, along with a number of other African heads of state, who see carbon markets as a way to generate badly needed climate finance.
- But African environmental groups have sharply criticized carbon markets, saying they represent a “false solution” to the climate crisis and will mostly enrich bankers and traders based outside the continent.
- The drive to scale up carbon markets in Africa and elsewhere is set to be a major agenda item at this month’s COP28 climate summit in Dubai.
Muslim community must have a seat for global climate change discourse (commentary)
- Muslims account for nearly a quarter of the world’s total population, much of which is impacted by climate change.
- At the same time, Islamic worldviews can bring solution-based perspectives to events like the upcoming COP28 climate conference later this month.
- “It should be recognized that Islamic frameworks of climate solution thinking are important, and the climate issues facing Muslims need to be at the forefront of climate discourse as well,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
The Cloud vs. drought: Water hog data centers threaten Latin America, critics say
- Droughts in Uruguay and Chile have led residents to question the wisdom of their governments allowing transnational internet technology companies to build water-hungry mega-data centers there.
- As servers process data, they need lot of water to keep them cool. But if demand grows as expected, the world will need 10-20 times more data centers by 2035, and they’ll be using far more water. Many will likely be built in economically and water-challenged nations already facing climate change-intensified droughts.
- Latin American communities fear that this “data colonialism” will consume water they desperately need for drinking and agriculture, and are critical of their governments for giving priority treatment to transnational tech giants like Google and Microsoft, while putting people’s access to a basic human necessity at risk.
- Surging digital data use by 2030 may cause each of us in the developed world to have a “digital doppelganger,” with our internet use consuming as much water as our physical bodies. But much of the stored data is “junk.” Critics urge that nations insist on tougher regulations for transnational companies, easing the crisis.
Critical questions remain as carbon credit deal in Sabah presses forward
- Details around a secretive “nature conservation agreement” signed in 2021 between a Singaporean company and the government of Sabah, a Malaysian state on the island of Borneo, remain elusive.
- Several internationally known companies that work in climate mitigation have said they’re not affiliated with the agreement, despite implications by Jeffrey Kitingan, a deputy chief minister and the deal’s primary backer, that they are involved.
- Kitingan also revealed that Hoch Standard, the Singaporean company, is controlled by a single director through another company registered in the British Virgin Islands.
- Kitingan said the project is moving forward, leading to renewed calls from civil society, Indigenous and research organizations for the release of more details about the agreement.
Amid record melting, countries fail again to protect Antarctic waters
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with protecting marine life and managing fisheries in the Southern Ocean, met from Oct. 16-27 in Hobart, Australia, with 26 member countries and the European Union participating.
- For the seventh year in a row, the CCAMLR declined to establish new marine protected areas (MPAs) around Antarctica, despite having committed to creating “a representative network of MPAs” in 2009.
- Scientists, conservationists and some governments have been pushing for greater protections, concerned that the melting ice in Antarctica has reached alarming levels, jeopardizing some key populations of penguins, krill, whales, seals and other marine animals.
- The stalemate came even as a new threat to wildlife emerged in the region: the discovery last week that a virulent form of avian flu had reached Antarctic bird colonies.
With record ocean temps, is the Great Barrier Reef facing catastrophe?
- The inaugural international edition of the famed South by Southwest (SXSW) film festival and conference took place from October 15-22, 2023 in Sydney and Mongabay spoke with some of the most interesting presenters there.
- On this edition of the Mongabay Newscast, multiple guests working in coral reef conservation, kelp reforestation and sustainable agriculture detail their projects and challenges they’re tackling.
- Like the catastrophic Great Barrier Reef bleaching event of 2016, if the current conditions line up just right, “we could lose a huge part of the reef by February,” says guest Dean Miller of the Forever Reef Project, which is now racing to add the final coral specimens to its “biobank.”
- Guests also include John “Charlie” Veron from the Forever Reef Project, Mic Black from Rainstick, and Adriana Vergés from the Kelp Forest Alliance.
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.
Meet the farmers in southeastern Spain fighting desertification
LOS VÉLEZ, Spain — Southeastern Spain faces a pressing environmental challenge: the encroachment of the Sahara Desert. This northward advance results in reduced rainfall, soil degradation, and severe droughts driven by climate change, jeopardizing centuries-old agricultural lands. In response to these challenges, local farmers are increasingly turning to regenerative agriculture practices. These innovative methods aim […]
As oceans warm, marine heat waves push deep beneath the surface, study shows
- A new study found that the ocean experiences the most intense marine heat waves at a depth of between 50 and 250 meters (160 and 820 feet), where a large portion of the ocean’s biodiversity can be found.
- It also found that parts of the ocean between 250 and 2,000 m (6,600 ft) had less intense but longer marine heat waves, with a duration twice as long as at the surface.
- The intensity and duration of marine heat waves could have widespread effects on marine biodiversity, increasing the likelihood of species displacement and mortality, the study suggests.
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.
How nonprofit journalism revealed many problems with the UN’s climate neutrality claims
- Despite claiming to be 95% “climate neutral,” the United Nations — a long-standing and vocal proponent of climate action — isn’t, a new report has found.
- Mongabay teamed up with reporters at The New Humanitarian in a yearlong investigation spanning multiple countries to investigate the U.N.’s claims.
- The investigation found that many projects that issue carbon credits to the U.N. were linked to environmental damage or displacement, and 2.7 million out of 6.6 million credits were linked to wind or hydropower — which experts say don’t represent true emissions reductions.
- Investigative reporter Jacob Goldberg from The New Humanitarian joins the podcast to explain how the team arrived at these surprising findings.
Return of the wolf to Nepal’s Himalayas may threaten snow leopards
- The return of wolves to Nepal’s Himalayan region is putting greater pressure on populations of naur, or blue sheep — and by extension on snow leopards, whose main prey is naur.
- New research shows that naur tend to exhibit greater vigilance in areas where both wolves and snow leopards are present, while lowering their guard somewhat when no wolves are around.
- Conservationists say the growing wolf presence threatens snow leopards through direct competition for food and through stressing out, and weakening, naur populations.
- Snow leopards already face pressure from common leopards and tigers, which are moving further uphill in response to both human threats and a changing climate.
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.
On Jakarta’s vanishing shoreline, climate change seen abetting child marriages
- Marriage before the age of 18 is classified as a form of gender-based violence by the United Nations, but is commonly practiced in low-income communities to mitigate household economic pressures.
- On Jakarta’s northern coastline, child marriage is common in fishing communities responding to inflationary pressures and declining stocks of fish in near-shore waters.
- Janah, now 23, fears she lacks the agency to break a cycle that saw her married at the age of 16.
At Climate Week, guaranteeing Indigenous land rights and funding is crucial (commentary)
- Indigenous territorial rights are likely to again be affirmed as vital to facing the climate crisis during Climate Week events in New York City from September 17-24.
- Such statements are welcome but rarely do they come with guarantees of territorial rights or climate finance for Indigenous communities to steward and protect those lands, however.
- “Discourses about facing the climate crisis are worth next to nothing if they are not accompanied by territorial guarantees and resources for those who keep the biomes standing,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
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.
‘We don’t have much time’: Q&A with climate scientist Pierre Friedlingstein
- “It’s not going in the right direction yet,” Pierre Friedlingstein tells Mongabay of the effort to meet the Paris Agreement goals; a member of the IPCC and a climate professor, he says he’s mildly optimistic about the trend in global emissions.
- Friedlingstein says he’s hoping deforestation will go down in the coming years in Brazil, but he’s not sure that Indonesia, another major global carbon sink, is ready to go in the right direction at the moment.
- He says the COVID-19 pandemic showed that climate is still “not on the top of the list” of government priorities, given that all nations sought to boost economic growth after lockdowns, despite the carbon emissions they incurred.
NASA satellites reveal restoration power of beavers
- A new partnership between NASA and researchers is measuring the impact of beavers reintroduced to landscapes in Idaho.
- Beavers are one of the world’s most powerful ecosystem engineers, building new habitats by slowing water flow and reducing flooding, while also boosting biodiversity.
- Beavers are all the more important in an age of rapid climate change, as they produce wetter and more resilient habitats, even in the face of wildfires.
- “NASA is interested in how satellite Earth observations can be used for natural resource management,” a member of the space agency’s Ecological Conservation Program tells Mongabay.
Study: Tricky balancing act between EV scale-up and mining battery metals
- A recent study finds rapidly switching to electric vehicles could significantly cut emissions but also increase demand for critical battery metals like lithium and nickel.
- Mining metals like lithium has major environmental impacts including deforestation, high water use, and toxic waste.
- Electrifying heavy-duty vehicles requires substantially more critical metals than other EVs and could account for 62% of critical metal demand in coming decades despite making up just 4-11% of vehicles.
- The researchers recommend policies to support recycling, circular economies, alternative battery chemistries, and coordinated action to balance environmental and material needs.
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.
‘In business to save the planet,’ Patagonia says people & planet should be the priority of corporations
- In the words of its founder, outdoor gear company Patagonia exists to “force government and corporations to take action in solving our environmental problems.”
- In 2022, the company made headlines when founder Yvon Chouinard announced the transfer of company ownership ($3 billion in assets and $100 million in annual profits) to a nonprofit and a trust, the dividends of which would go to environmental advocacy organizations, making “Earth the only shareholder.”
- Joining our podcast to discuss Patagonia’s 50-year legacy is environmental action and initiatives director Beth Thoren, who shares the company’s theory of change, discusses how traditional capitalism is no longer working for people or the planet, and its poignant “Not Mars” campaign.
- “If we continue to live in the world where shareholder value is the only thing that is valued, we will burn up and die,” she says.
In a world of climate risks, Sri Lanka is finding ways to adapt
- In a landscape of interconnected and mutually compounding risks, climate change has emerged as a key risk factor for Sri Lanka, specifically for vulnerable sectors and groups.
- Risk management frameworks need to acknowledge and incorporate these emerging risks. While Sri Lanka already has risk management mechanisms and instruments in place, there are opportunities to scale up these mechanisms, close existing gaps and mobilize additional means of implementation.
- Sri Lanka is in the process of strengthening its national environment policy related to climate change, including through global and international processes, which could remove constraints and help enhance risk management in the country.
- Key areas for improving and future-proofing Sri Lanka’s risk management framework include awareness creation, education, and the wider enabling environment; multi-stakeholder collaboration and decision-making processes; leveraging new and innovative risk management instruments; and connecting the national to the international level, such as the U.N. climate change convention negotiations or the Global Shield initiative.
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.
REDD+ projects falling far short of claimed carbon cuts, study finds
- New research reveals that forest carbon credits are not offsetting the vast majority of emissions that providers claim.
- A team of scientists looked at 26 REDD+ deforestation-prevention project sites on three continents, leading to questions about how the developers calculate the impact of their projects.
- The researchers found that about 94% of the credits from these projects don’t represent real reductions in carbon emissions.
- Verra, the world’s largest carbon credit certifier, said the methods the team used to arrive at that conclusion were flawed, but also added it was in the process of overhauling its own REDD+ standards.
EVs offer climate hope, but total auto supply chain revamp is vital
- Internal combustion engine vehicles (ICE) and electric vehicles (EV) both have supply chains that generate significant environmental impacts. Experts argue that circular economy principles — based on reducing, reusing and recycling materials — are key to increasing EV sustainability. But the auto industry has far to go to get there.
- Circularity is deemed particularly important for EVs, which are tipped as a vital climate solution and as the future of light transport across the globe. But their introduction globally is dependent on soaring material resourcing and production, all coming with “embedded emissions,” pollution and other impacts.
- At present, circularity is low in the auto industry, but experts see great potential, particularly for EV batteries. They argue for changes all along the supply chain to reduce material use and encourage advanced recycling.
- Others emphasize a holistic approach to land transport that reduces demand for automobiles in favor of public transportation. Circular economy solutions need to be achieved quickly in the transport sector if emissions are to be cut enough to help curb climate change and reduce pollution and other environmental ills.
Three new studies on Indigenous conservation for International Indigenous Peoples Day
- Indigenous peoples and local communities have nuanced, in-depth knowledge of climate change impacts that needs to be recognized by scientists and policy-makers, according to researchers.
- Industrial development threatens nearly 60% of Indigenous lands worldwide and renewable energy infrastructure expansion could become a dominant driver, according to a new peer-reviewed study.
- Indigenous groups and a growing body of studies emphasize the importance of Indigenous leadership, rights and land tenure for climate change mitigation.
From debt to diversity: A journey of rewilding, carbon capture and hope
- Rewilding has transformed an English estate from a debt-ridden, conventional farm to a profitable haven of biodiversity.
- A study also shows that the rewilded farmland at Knepp absorbs more carbon dioxide than conventional farms, providing hope for climate change mitigation and soil restoration.
- The U.K. is transitioning to a new environmental land management framework offering incentives for practices that restore soil health and biodiversity, but private investment is still needed to bridge the funding gap.
- Nature restoration investment mechanisms to attract private investment are being developed using Knepp data and government funding.
Internal combustion vs. EVs: Learning from the past to boost sustainability
- Sales of electric vehicles are gathering pace, with numbers taking to the road steadily increasing in the U.S., Europe, and China; though that rollout is lagging far behind in emerging economies, especially in the Global South. That’s an issue that will need to be addressed if the world is to maximize transportation carbon cuts.
- EVs clearly outperform internal combustion engines (ICEs) in their vehicle carbon emissions. But assessments must be made across the whole life cycle of both types of vehicles to create true comparisons of environmental impacts and learn from them. EVs, for example, require lithium, the mining of which seriously pollutes.
- Even the amount of emissions produced by EVs needs to be carefully evaluated. While the cars themselves are clean, total emissions vary greatly depending on how the electricity to run them is produced (if the electrical grid is powered by coal, oil or gas, that’s very different than energy coming from wind and solar).
- For EVs to achieve their full sustainability potential, every aspect of automotive production needs to be assessed not only for environmental impacts, but for their effects on society, livelihoods and more. The use of a circular economy blueprint for creating clean EV supply chains will be assessed in part two of this story.
Nepal’s climate change adaptation strategy needs One Health approach (commentary)
- It is expected that climate change will adversely affect Nepalese biodiversity, human well-being, and economy, from a retreat of glaciers, agricultural losses, and impacts on tourism.
- The spread of infectious diseases can also be fueled by rising temperatures and shifting precipitation patterns.
- “Given the simultaneous exposure of animal and human populations to climate change impacts such as floods and landslides, proactively preparing for and combating ensuing issues like epidemics are best tackled using an integrated One Health approach,” a new op-ed argues.

Progress is slow on Africa’s Great Green Wall, but some bright spots bloom
- Africa’s ambitious Great Green Wall, a mosaic of reforestation efforts to stop desertification, has been plagued by delays and challenges.
- Some reforestation efforts, however, have tasted success, becoming a model for many to follow.
- Experts suggest moving away from viewing the initiative as merely a tree-planting exercise and instead seeing it as a holistic, participatory approach that involves local communities and helps them build their livelihoods and incomes.
- Challenges still abound, however, including a volatile security situation, lack of water, coordination challenges, and scattered long-term monitoring of reforested patches.
Funding circularity: Investing in Asia’s circular economy business models
- As global raw material consumption soars and pollution skyrockets, the need to transition from a consumptive linear economy to a circular one — centering on reduced resource extraction and reuse and recycling to achieve zero waste — has grown more urgent. But paying for that transition poses many challenges.
- Circulate Capital is a Singapore-based investment management firm that finds and funds companies in emerging economies that are developing innovative circular economy business models.
- The company currently invests in companies in South and Southeast Asia that have come up with effective solutions to prevent plastic waste from reaching the ocean. It’s also looking to expand to Latin America.
- “It’s a whole way of creating value that decouples the extraction of resources from the environment and finding ways of making those resources more productive,” Ellen Martin, chief impact officer at Circulate Capital, told Mongabay.
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.
Green gains: Localized efforts leave a mark, notably in drier areas, study shows
- Spurts of green spread across the African continent taken together accounted for over 400,000 square kilometers (154,000 square miles) of greening, an area the size of Zimbabwe.
- According to researchers, it’s important to distinguish how much of this greening is due to human efforts and how results much from broader climatic shifts.
- The team compared greening trends in target plots with neighboring plots; the latter, they hypothesized, would reflect changes in vegetation driven by broader climatic trends.
- Despite these advances, satellite imagery-based monitoring of vegetation growth can be a blunt instrument, especially where the data don’t capture differences in the greening, like those arising from agricultural expansion or reforestation.
A just energy transition requires better governance & equity in the DRC
- The global energy transition has increased demand for critical minerals involved in the making of products such as lithium-ion batteries, solar panels and other renewable energy sources.
- In the Democratic Republic of Congo, this demand has fueled a poorly regulated mining sector that has forced Indigenous communities off their land, polluted water and air, and given little back in the way of infrastructure or development.
- The DRC has also recently opened 27 blocks of land for oil exploration under the auspices of lifting the nation out of poverty, but our guests say the handling of these other mineral revenues doesn’t bode well for an equitable oil boom.
- Joseph Itongwa Mukumo, an Indigenous community member of Walikale in the North Kivu province and director of ANAPA-DRC, and Christian-Géraud Neema Byamungu, Francophone editor at the China Global South Project, speak with Mongabay about the impacts of mining on local and Indigenous communities and what DRC residents need for a just energy transition.
Asian Development Bank’s climate commitments require greater accountability (commentary)
- The Asian Development Bank committed to achieving full alignment with the 2016 Paris Agreement by this month, though it still considers fossil fuel projects to ’not be unaligned’ with this goal.
- It also has announced an Innovative Finance Facility for Climate, which aims to invest billions of dollars to reduce greenhouse gas emissions and build resilience for communities already suffering the impacts of the climate crisis in Asia.
- However, these ambitions have no chance of success without an increased commitment to safeguards and accountability, a new op-ed argues, because projects aimed at mitigating climate change can–and do–go wrong.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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?
Blue carbon deserves a green light for the climate fight (commentary)
- Marine habitats like mangrove forests, seagrass meadows, salt marshes, and kelp forests cover just 0.2% of the ocean surface and provide shelter & food for myriad life forms while containing 50% of the carbon sequestered in marine sediments.
- Yet at a time when the world needs to keep carbon sequestered to mitigate the effects of climate change, about 35% of the world’s mangroves and 30% of all seagrass meadows have been lost or degraded.
- A new op-ed argues that the world should be moving to reverse these trends: “We are currently throwing away a golden opportunity to tackle the climate crisis, bolster sustainable fisheries and allow wildlife to thrive.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Extreme temperatures and erratic weather disrupt Bangladesh’s famous Rajshahi silk industry
- Since the 13th century, Rajshahi, named “Silk City,” has been known for its finest silk, which local growers have produced.
- Earlier, the product was named Bengal silk or Ganges silk. Considering the prospects and reputation of the trade, the then-Pakistan government started producing silk officially. Consequently, it established a silk factory in Rajshahi in 1961, which washanded over to Bangladesh Sericulture Development Board in 1978.
- The silk sector in Rajshahi grew as farmers of the neighboring districts used to produce high-quality silk yarns by the larvae of moths fed on fresh mulberry leaves, which were later used for luxurious clothing items. There are three types of silk produced in Rajshahi: mulberry, endi and tassar, with mulberry silk being the finest and most expensive.
- However, Bangladesh’s once-famous silk industry has faced difficulties in recent years, including the excessive dependency on imported low-cost yarn and different bacterial and viral diseases triggered by constantly variable temperatures and humidity.
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.
Antarctic warming alters atmosphere, ice shelves, ocean & animals
- The world’s latest record-high temperatures are increasingly putting Antarctica’s role in regulating global climate and ocean currents at risk. But so far, most signs indicate that the continent has not yet reached a point of no return. A rapid reduction in fossil fuel extraction and carbon emissions could still prevent the worst outcomes.
- Increased persistence of the Antarctic ozone hole over the past three years could be an indication of climate change, as it cools the south polar stratosphere, though high variability in this phenomenon and its complexity make causality difficult to prove.
- As global warming continues to melt Antarctica’s edges, a modeling study shows that fresh water going into the ocean could result in the next three decades in a more than 40% slowdown in the currents carrying heat and nutrients northward, essential to sustain ocean life as we know it. If ice shelves melt, allowing Antarctica’s ice sheets to flow to the sea, sea level rise will escalate.
- The latest discovery of a new colony of emperor penguins (Aptenodytes forsteri) in a marginal habitat of the Antarctic is good news, but also bad news, as it further highlights the vulnerability of the species as Antarctic ice masses destabilize — volatility that threatens their survival.
Climate warming alters offspring production of birds, study shows
- A global meta-study investigating the effects of climate change on bird reproduction has found an overall decline in annual offspring production over 50 years.
- Offspring production in migratory and large birds decreased, whereas it increased in smaller-bodied and sedentary species.
- Migratory species may find it difficult to adapt to a rapidly changing climate in their breeding and wintering areas. Large birds may have problems adapting to changing climate conditions because they tend to live a ‘slower pace of life’ and have offspring only once a year.
- Curbing our carbon dioxide emissions will halt rising temperatures impacting bird species, say the study’s authors. People can also help boost bird reproduction by creating a cooler environment for bird nests in yards and parks through dense vegetation during heat waves.
U.N. climate chief calls for end to fossil fuels as talks head to Dubai
- International climate talks began in Bonn, Germany, on June 5.
- A key part of the discussion will be the global stocktake, assessing progress toward the emissions cuts pledged by nations as part of the 2015 Paris climate agreement.
- Discussions will work to provide the technical details of the stocktake, but the consensus is that the world is not on track to cut emissions by 50% by 2030, which scientists say is key to keeping the global temperature rise below 1.5°C (2.7°F) over pre-industrial levels.
- The talks are a precursor to COP28, the annual U.N. climate conference, scheduled to begin Nov. 30 in Dubai, United Arab Emirates, which is a major oil- and gas-producing nation.
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.
Expedition to Pacific ecosystems hopes to learn from their resilience
- An expedition led by National Geographic’s Pristine Seas project will voyage across the Pacific over five years to gather information about marine ecosystems needing protection.
- The Pristine Seas team will collaborate with Pacific island nation governments, communities, Indigenous and local peoples, and local scientists, to gather data and produce films.
- The first stop of the expedition will be the southern Line Islands, part of Kiribati, to understand how its reefs recovered after an El Niño triggered a large-scale bleaching event in 2015 and 2016.
Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.
An Asian grass helps Mexican farmers build resilience to climate change
- A longtime ingredient in fragrances, vetiver is becoming an ally for farmers facing the impacts of climate change.
- Planting vetiver grass in tropical and subtropical regions is a cheap and simple way to prevent soil erosion, capture carbon dioxide and detoxify the soil, with this nature-based solution already in use for decades in India and now becoming increasingly popular elsewhere.
- In Mexico, where 76% of the land suffers from erosion, one environmental expert in Veracruz state has become a pioneer in using vetiver to stop soil erosion.
- The method used on a tobacco farm helped reduce crop loss and improve harvests significantly in just its first year of implementation.
Sri Lanka aims to restore ancient irrigation tanks in climate change plan
- Sri Lanka’s well-recognized village tank cascade systems, ancient irrigation structures that interconnect small tanks for rainwater-reliant cultivation, are a remarkable adaptation and mitigation strategy practiced on the island for dealing with extreme climatic conditions.
- Some of the tank cascade systems are likely to have been built around 500 BCE and continue to function sustainably, though not at full capacity; experts are calling for their restoration with extreme care to ensure optimum functionality.
- Recognized as a globally important agricultural heritage system by the U.N. Food and Agriculture Organization (FAO), most of these tanks are now neglected and under pressure from the changing climate, land use, population and agricultural intensification, despite their value as a unique climate adaptation plan.
- Sri Lanka’s dry zone has more than 14,000 small ancient village tanks with many still in good shape, supporting 246,000 hectares (608,000 acres) of paddy cultivation, about 39% of the total irrigable area, but poor maintenance has rendered many others dysfunctional.
Guyana gets ‘Drilled’: Weighing South America’s latest oil boom with Amy Westervelt
- The South American nation of Guyana entered into an arrangement with ExxonMobil after vast oil resources were discovered off its coast, but many questions remain about what Guyana will actually reap from the project.
- Joining the podcast to discuss the project's potential environmental, social, and economic impacts is award-winning journalist and podcaster Amy Westervelt: the 8th season of her acclaimed podcast “Drilled” examines this issue.
- Westervelt also discusses the current state of the world’s efforts to address climate change, the ongoing realities that are seemingly in direct contradiction with those goals, and her views on the power of podcasting.
- “What a total failure of international climate negotiations that Global South countries [are] in this position of having to use oil money to pay for climate adaptation. That’s ridiculous,” Westervelt says during the interview.
Is there a ‘lighter side’ to our possible environmental apocalypse? (commentary)
- Ocean activist and author David Helvarg deals with dark thoughts about the state of the world environment with humor in a new op-ed.
- “As a professional ocean advocate, I try and see the bright side of environmental and climate impacts such as sea level rise. While the ocean today covers 71% of the planet, it could soon cover 75%. More ocean means more ocean to love,” he jokes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
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.
Rewilding animals could be key for climate: Report
- A new report published in Nature Climate Change suggests that trophic rewilding, or restoring and protecting the functional roles of animals in ecosystems, is an overlooked climate solution.
- Reintroducing just nine species or groups of species (including African forest elephants, American bison, fish, gray wolves, musk oxen, sea otters, sharks, whales and wildebeest) would help limit global warming to less than the 1.5°C (2.7°F) threshold set by the Paris Agreement, according to the report.
- Animals play a significant role in how much carbon plants, soil and sediments can capture, as they redistribute seeds and nutrients and disturb soil through digging, trampling, and nest-building.
- The report emphasizes the need for a change in mindset within science and policy to take advantage of the vast potential of wildlife, while working closely with local communities to address social issues that can affect conservation efforts.
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.
Sea level rise looms, even for the best-prepared country on Earth
- The Netherlands, a low-lying European country with more than a quarter of its land below sea level, has been going to great lengths to protect itself from the impacts of climate change, including sea level rise and extreme weather events like heavy rain.
- But even for the Netherlands, a country with the wealth and experience to address these issues, the future remains uncertain, mainly because a range of possible scenarios could play out after 2050.
- According to the Intergovernmental Panel on Climate Change, a low-emissions scenario for the greenhouse gases that amplify global warming could elevate sea levels about half a meter (1.6 feet) above present levels by 2100; a higher-emissions scenario could lead to a 2-m (6.6-ft) rise by 2100 and a 5-m (16.4-ft) rise by 2150.
- Experts say that most other countries need to take the threat of sea level rise more seriously, and that engineering challenges, a lack of awareness and education, sociocultural concerns, and financial constraints are hampering their preparation.
IPCC warns of ‘last chance’ to limit climate change via drastic emissions cuts
- The United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its sixth “synthesis” report March 20, after its approval by world leaders at a weeklong meeting in Switzerland.
- The report’s authors conclude that immediate reductions in carbon emissions are necessary to limit the rise in the global temperature to 1.5° Celsius (2.7° Fahrenheit) above pre-industrial levels.
- Scientists, activists and observers are calling for an end to fossil fuel use.
As Himalayas thaw, snow leopards scramble for habitat: Q&A with Bikram Shrestha
- Snow leopards face a severe prospect of both a shrinking range and fragmented populations as climate change makes their Himalayan homeland less hospitable.
- Bikram Shrestha is a leading snow leopard researcher in Nepal, where he says it’s possible there may not be habitable space for the big cat as temperatures rise.
- He says a key action to conserving snow leopards is to ensure a plentiful supply of prey species, which means ensuring there’s enough suitable habitat for species like Himalayan tahrs and martens.
- Shrestha spoke with Mongabay’s Abhaya Raj Joshi about the need for more research into the world’s most elusive big cat, the prospect of conflict with humans, and why some locals want snow leopards killed.
Reef ruckus: Fish fights erupt after mass coral bleaching, study finds
- An international team of researchers studied the behavioral changes among butterflyfish on a series of reefs in the Indo-Pacific before and after the 2016 global mass coral bleaching event.
- They found that following the bleaching event, fish behaved more aggressively toward one another in their newly degraded reef home.
- The energetic toll of encounters involving fighting and chasing one another could have implications for the long-term survival of reef fish species, the study authors conclude.
- Given rates of ocean warming and predictions for more frequent and intense coral bleaching over the longer term, it’s unclear whether reef fish have the capacity to adapt their behavior to their rapidly changing environments.
Himalayan catfight looms as tigers, leopards venture into snow leopard land
- A warming climate threatens to push Nepal’s three big cat species — tigers, leopards and snow leopards — into closer proximity to each other, with unknown consequences for the survival of each.
- Conventional wisdom says tigers prevail in the country’s southern plains, leopards in the mid-country hill region, and snow leopards in the Himalayas.
- But both tigers and leopards have been observed at elevations above 3,000 meters (9,800 feet), well within snow leopard territory, although conservationists say tigers are less likely to persist at these altitudes over the long term.
- A complicating factor is the role of humans, with human settlements also moving up in altitude in search of more suitable conditions, and putting all four apex species in direct competition.
Goodbye to blue skies? The trouble with engineered solutions
- Humanity has created a lot of ecological problems, and many of the proposed solutions come with giant price tags — or the things lost can even be priceless, like the sight of a blue sky — with no guarantee of solving the situation in the long term.
- Many such solutions — like Australia’s deliberate introduction of the toxic cane toad, which has wreaked havoc on the country’s wildlife — create new problems.
- Solar geoengineering to slow climate change would have the most visible effect to all, likely making the sky appear white: No more blue skies—but how would this affect the global plant community’s ability to photosynthesize, would it harm agriculture?
- Pulitzer Prize-winning author Elizabeth Kolbert joins the Mongabay Newscast to talk about her latest book, “Under a White Sky,” which examines these interventions, the problems they come with and humanity’s seeming inability to stop turning to them.
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.
Trees with edible leaves can boost human nutrition: New book, free download
- Tree planting is widely promoted as a solution to challenges ranging from climate change to biodiversity loss, desertification, and more.
- One less-appreciated benefit of growing trees is for their leaves for human nutrition, but a new book, “Trees with Edible Leaves: A Global Manual,” details more than 100 species whose leaves are highly nutritious.
- Trees are also much easier to grow than annual vegetables, being very simple to maintain once established, and benefit other crops when grown in agroforestry settings.
- Mongabay interviewed Eric Toensmeier, the author of this new resource, which is available as a free download.
Updated guide gives practical advice for buyers of tropical forest carbon credits
- An updated guide written by eight conservation and Indigenous organizations offers a detailed path forward for companies that want to compensate for their carbon emissions in addition to decarbonizing their supply chains.
- Though the carbon market faces criticism over the true value it brings to climate change mitigation, proponents say it can complement earnest efforts to decarbonize supply chains if used properly.
- The updated Tropical Forest Credit Integrity guide calls for due diligence on the part of companies to ensure the credits they purchase will result in climate gains.
- The authors of the guide also stress the importance of including Indigenous peoples and local communities in decisions about offset efforts.
Peatland restoration in temperate nations could be carbon storage bonanza
- Much maligned and undervalued over the centuries, temperate peatlands have seen a lot damage in that time — drained for agriculture, planted with trees, mined for horticulture and fuel. But in an age of escalating climate change, people are now turning to restoration.
- As potent carbon sequesters, peatlands have only recently been given new attention, with active restoration taking place in many nations around the world. This story focuses on groundbreaking temperate peatland restoration efforts in the U.S. Southeast, Scotland and Canada.
- Every temperate peatland is different, making each restoration project unique, but the goal is almost always the same: restore the natural hydrology of the peatland so it can maximize carbon storage and native biodiversity, and improve its resilience in the face of climate change and increasingly common fires in a warming world.
With climate change, Nepal’s leopards get a bigger range — and more problems
- Climate change will make higher-elevation areas of Nepal suitable habitat for leopards, a new study shows.
- This is expected to push the big cats into increased conflict with humans and more competition with snow leopards.
- Most of the current and new habitat will fall outside protected areas, and the leopards’ preferred prey may not be available there, which could prompt the predators to hunt livestock.
- But the finding could also be an opportunity to conserve leopards in their potential new habitat, by educating communities there, ensuring availability of wild prey, and drawing up wildlife management plans.
In wake of ‘natural’ disasters, not reducing biodiversity loss is a big missed opportunity (commentary)
- Following the progress of the COP15 biodiversity summit, it’s time to come together to fully leverage the power of nature to build a prosperous, disaster-resilient future, a new op-ed argues.
- “Working with – and making full use of – the power of nature, and taking advantage of much existing knowledge, would prove a major step forward,” writes a NOAA senior scientist.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay or NOAA.
The EU banned Russian wood pellet imports; South Korea took them all
- In July 2022, the European Union responded to the war in Ukraine by banning the import of Russian woody biomass used to make energy. At roughly the same time, South Korea drastically upped its Russian woody biomass imports, becoming the sole official importer of Russian wood pellets for industrial energy use.
- The EU has reportedly replaced its Russian supplies of woody biomass by importing wood pellets from the U.S. and Eastern Europe. But others say that trade data and paper trails indicate a violation of the EU ban, with laundered Russian wood pellets possibly flowing through Turkey, Kazakhstan and Kyrgyzstan to multiple EU nations.
- EU pellet imports from Turkey grew from 2,200 tons monthly last spring to 16,000 tons in September. Imports from Kazakhstan and Kyrgyzstan reportedly rose too, even though neither has a forest industry. A large body of scientific evidence shows that woody biomass adds significantly to climate change and biodiversity loss.
- Enviva, the world’s largest woody biomass producer, which operates chiefly in the Southeast U.S., may be the big winner in the Russian biomass ban. Since the war began, Enviva has upped EU shipments, and also announced a 10-year contract with an unnamed European customer to deliver 800,000 metric tons of pellets annually by 2027.
Reciprocal Water Agreements protect millions of hectares of Bolivian forest
- In return for committing to protect their water producing forests, farming families living in upper watersheds receive incentives to help them develop sustainable production initiatives and to connect their homes to drinking water.
- These incentives are mainly funded by the municipality and from water service providers via a monthly payment made by service users.
- The model has expanded rapidly in Bolivia and is beginning to be replicated in Colombia, Peru, Ecuador and Mexico.
The tiger in the snow: Cameras capture abundance of life in a Himalayan refuge
- Camera traps have captured tigers roaming at an elevation of 3,165 meters (10,384 feet) in eastern Nepal’s lower Himalayas — the highest they’ve ever been recorded in the country.
- Experts suggest a range of factors for this, including a growing tiger population that’s crowding some of the big cats out of the lowland plains and further uphill.
- Another set of camera trap images were captured in Dadeldhura district in western Nepal, which a previous study identified as a climate refugium, where temperatures remain relatively stable, allowing species to persist during regional and global climate changes.
- Other large mammals have also been recorded on camera trap here, including many that, like tigers, were previously thought to be confined to lower-elevation habitats.
Extreme heat takes a toll on tropical countries’ economies
- Extreme heat costs tropical countries more than 5% of their annual per capita GDP, new research shows, while more prosperous mid-latitude countries lose only about a 1% of GDP due to heat waves, which can even bolster economic growth in some instances.
- Poorer tropical countries suffer the worst effects of heat waves despite being least culpable and least economically capable of adapting.
- The effects of extreme heat and drought can hit hard in local communities, such as among Kenyan families who rely on cattle they can no longer feed.

- Here are the posts that captured the most reader attention in 2022.
2022’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2022.
- Hopeful developments this past year include the launch of negotiations on the world’s first legally binding international treaty to curb plastic pollution, a multilateral agreement to ban harmful fisheries subsidies and a massive expansion of global shark protections.
- At the same time, the climate crises in the ocean continued to worsen, with a number of record-breaking marine heat waves and an accelerated thinning of ice sheets that could severely exacerbate sea level rise, underscoring the need for urgent ocean-climate actions.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Hunting for future-proof marine plants in the acidic waters bathing a volcano
- The naturally acidic seawater near an underwater volcano in Italy mimic pH levels that according to worst-case climate projections will be common by the end of the century and beyond.
- Scientists are studying local seagrass and seaweed responses to the acidic conditions.
- One question is whether they could be used for restoration purposes in other places that may become more acidic in a not-so-distant future.
- Even so, some researchers point out that these carbon-sequestering marine plants face more immediate challenges from pollution, habitat degradation and warming waters that need addressing for restoration to succeed.
Mongabay’s 10 most popular videos of 2022
- Here we rewatch the top 10 favorite videos of 2022 on Mongabay’s YouTube channel.
- Indigenous communities and wildlife are among the main characters of the most-watched videos of the past year.
- Mongabay launched two new video series called “Chasing Deforestation” and “Consumed.”
The Netherlands to stop paying subsidies to ‘untruthful’ biomass firms
- On December 5, 2022, Mongabay featured a story by journalist Justin Catanoso in which the first ever biomass industry insider came forward as a whistleblower and discredited the green sustainability claims made by Enviva — the world’s largest maker of wood pellets for energy.
- On December 15, citing that article and recent scientific evidence that Enviva contributes to deforestation in the U.S. Southeast, The Netherlands decided it will stop paying subsidies to any biomass company found to be untruthful in its wood pellet production methods. The Netherlands currently offers sizable subsidies to Enviva.
- Precisely how The Netherlands decision will impact biomass subsidies in the long run is unclear. Nor is it known how this decision may impact the EU’s Sustainable Biomass Program (SBP) certification process, which critics say is inherently weak and unreliable.
- Also in December, Australia became the first major nation to reverse its designation of forest biomass as a renewable energy source, raising questions about how parties to the UN Paris agreement can support opposing renewable energy policies, especially regarding biomass — a problem for COP28 negotiators to resolve in 2023.
Australia rejects forest biomass in first blow to wood pellet industry
- On December 15, Australia became the first major economy worldwide to reverse itself on its renewable classification for woody biomass burned to make energy. Under the nation’s new policy, wood harvested from native forests and burned to produce energy cannot be classified as a renewable energy source.
- That decision comes as the U.S., Canada, Eastern Europe, Vietnam and other forest nations continue gearing up to harvest their woodlands to make massive amounts of wood pellets, in order to supply biomass-fired power plants in the UK, EU, Japan, South Korea and elsewhere.
- In the EU, forest advocates continue with last-ditch lobbying efforts to have woody biomass stripped of its renewable energy designation, and end the ongoing practice of providing large subsidies to the biomass industry for wood pellets.
- Science has found that biomass burning releases more carbon dioxide emissions per unit of energy produced than coal. Australia’s decision, and the EU’s continued commitment to biomass, creates a conundrum for policymakers: How can major economies have different definitions of renewable energy when it comes to biomass?
