At Bradford Island, near Bonneville Dam, the river carried more than water. Beneath the surface of the Columbia were toxic sediments, dumped near a place where Yakama people had fished since time immemorial. To officials, it was a cleanup site. To the Yakama Nation, it was a usual and accustomed fishing place, protected by treaty. To Davis Washines, known to many as Yellowash, it was also a crime scene. The victims, he said, were first the water, then the salmon and other life that depended on it, and then the people who depended on them. He did not speak that way for emphasis. He spoke from a life spent moving between law enforcement, ceremony, public service, and the river. Evidence mattered to him. So did harm, responsibility, and the obligations carried through Yakama law, culture, and memory. Yellowash died on May 1st, at his home in White Swan, Washington. He was 74. By then he had held many titles: Yakama Tribal Police chief, Columbia River Inter-Tribal Fish Commission police chief, member of the Yakama Tribal Council, chairman of the Yakama Nation General Council, government relations liaison in the Yakama Nation Department of Natural Resources, trustee, board chair, counselor, teacher, and ceremonial leader. The titles marked a long public life. They did not fully describe it. He began that life in public service in 1973 with the Yakama Tribal Police Department and rose to chief in 1986. He later returned to that role, and then became chief of police for the…This article was originally published on Mongabay

On May 28, 2026, Tedros Adhanom Ghebreyesus, the director-general of the World Health Organization, sent an open letter to the people of the Democratic Republic of Congo before traveling to the country for a field visit: “I am writing because I want to be with you in these moments. And I want you to know that you are not alone,” he wrote, before recalling his involvement during the deadly Ebola outbreak that struck the northeastern DRC between 2018 and 2020. Since May 15, the country has been facing a new outbreak, this time caused by the Bundibugyo variant, a strain of the disease for which there is currently neither treatment nor vaccine. Since the outbreak was declared, the death toll has continued to rise. According to the latest figures, DRC authorities recorded 121 confirmed cases with 17 confirmed deaths, as well as more than 1,077 suspected cases and 238 suspected deaths. The hemorrhagic fever first emerged in Ituri province, on the border with Uganda, before spreading to North Kivu province and to Uganda. That prompted Uganda to close its border with the DRC. While Ituri remains the worst-hit province, the risk of regional spread is high. On May 23, the Africa Centres for Disease Control and Prevention (Africa CDC) identified 10 other African countries at risk from this Ebola outbreak: Angola, Burundi, the Central African Republic, the Republic of Congo, Ethiopia, Kenya, Rwanda, South Sudan, Tanzania, and Zambia. As a result, the international response is intensifying. Dr. Macky Mbavugha is…This article was originally published on Mongabay

MANNAR, Sri Lanka — Each year, the arrival of greater flamingos transforms the lagoons of northern Sri Lanka into a mesmerizing spectacle of pale pink and white. Their synchronized movements across the shallow waters of Mannar attract birdwatchers, photographers, tourists and nature lovers from around the country and abroad. But behind this beauty lies a growing crisis. Recently, three flamingos were killed in Mannar after a collision with overhead power lines that crossed their flight path. Initial reports suggested electrocution, but according to Department of Wildlife Conservation (DWC) veterinary surgeon Balachandran Giritharan, who conducted the necropsies, the birds were not electrocuted. Instead, their long necks were slashed mid-flight when they struck the cables. The incident has renewed concerns among conservationists who have previously warned against energy infrastructure cutting across sensitive wetland habitats such as Vankalai Sanctuary, another Ramsar wetland in Mannar. Environmentalists had identified large waterbirds such as flamingos as being vulnerable to collisions. The latest flamingo deaths also add to the mounting environmental concerns surrounding development projects, particularly in Mannar, including proposed wind power projects. The issue drew international attention after the withdrawal of developer Adani Green Energy Limited (AGEL) from a disputed wind power project in Sri Lanka earlier this year. The Mannar region, with its strategic wind resources, has increasingly become a battleground between renewable energy expansion and biodiversity conservation.

The price of financial stability should not be environmental destruction. Yet when countries turn to the International Monetary Fund (IMF) for help, their forests may quietly suffer. The IMF is currently reviewing the design of its lending programs, and it is time for change. Its recipe for getting economies back on track often features required reforms such as cutting government expenditure, increasing revenue collection through taxes or utility tariff increases, winding down public ownership of state-owned enterprises and encouraging the private sector to step up: austerity in other words. These policies are meant to restore stability in times of crisis, but growing evidence shows that IMF programs often fall short in helping countries break out of the cycle of economic and financial distress. Instead, they can trigger collateral damage in the form of negative health outcomes, worsened poverty and inequality and eroded social protection. Image by Forster et al., 2026 (CC BY 4.0). Our new research provides evidence that these programs also have an important and often overlooked environmental dimension, revealing that countries experience 9.2% higher annual tree cover loss during years in which they are under an IMF program. In a typical three-year IMF program, this amounts to forest loss the size of Barbados. This finding comes as no surprise as IMF programs are known to generally cut government spending, and environmental protections are often the first to go. These conditions that come in exchange for financial assistance are a major shortcoming when it comes to effects on forests,…This article was originally published on Mongabay

A newly released book documenting urban forestry efforts across Africa argues that trees and green spaces are no longer a luxury for African cities, but a critical response to climate change, biodiversity loss, and urban inequality. Published by Johannesburg City Parks and Zoo (JCPZ), Urban Forests and Green Spaces in Africa: Case Studies and Lessons from Across the Continent brings together 34 case studies from 14 African countries, covering everything from restoring biodiversity around wetlands in Rwanda’s capital Kigali, creating Miyawaki forests (forests with native trees planted closely together) in Kenya’s capital Nairobi, greening heat-stressed neighborhoods in Zimbabwe’s capital Harare, transplanting baobabs in Senegal to rehabilitating degraded urban land in South Africa. Hot days, hot nights, and heatwaves have become more frequent across Africa, concludes the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, the world’s most authoritative scientific assessment on climate change. The report also finds that coastal cities are vulnerable to floods related to rainfall events and sea level rise. Palm-lined trees provide near-continuous canopy cover along a boulevard in Bahir Dar, the capital of Ethiopia’s Amhara region. The book notes that canopy closure along some of the city’s main streets approaches 100%, making Bahir Dar one of the most heavily treed urban centers in Africa. Image courtesy of Cathy Watson/CIFOR-ICRAF. As African cities experience rising temperatures, worsening floods, biodiversity loss, and rapid urbanization, the book argues that urban forests and green infrastructure are essential tools for climate resilience. Beyond storing carbon, trees and green spaces…This article was originally published on Mongabay

In the Amazon, a forest can remain on the map while losing much of what makes it function. The Amazon rainforest is often discussed through a few familiar measures: deforestation, carbon, protected areas, and tipping points. Each is useful. But they do not fully explain why biodiversity continues to decline even where maps still show forest, laws exist, and international pledges sound ambitious. A territory can be recognized and still be invaded. A satellite can detect illegal clearing and still fail to trigger a penalty. A story can describe crisis and still leave readers unsure what can be done. Six gaps help explain the problem: finance and forest economy, governance, enforcement, forest function, Indigenous rights, and narrative. They overlap in ways that make each harder to close. The finance and forest-economy gap Protecting forests costs money every year. It requires staff, transport, monitoring, community work, legal support, fire control, restoration, and the ability to respond when illegal actors arrive. Yet the money available for those tasks remains far below the scale of the problem. Globally, UNEP estimates that forest investments need to reach about $300 billion a year by 2030 to meet climate, biodiversity, and land-degradation targets. The report also notes that this figure excludes some enabling conditions, including governance and law enforcement, which means the true need is probably higher. The Brazilian Amazon shows the imbalance more clearly. WWF and Conservation Strategy Fund estimate that Brazil needs about $12.8 billion a year to meet forest policy goals.

Why do we need deep-sea mining? Given the potential consequences for the health and biodiversity of the ocean, that seems a vital question to answer before any commercial mining starts. The question is even more important as the economic case for deep-sea mining is being increasingly undermined by financial evidence, and is nowhere near strong enough to justify the risks to ecosystems we barely understand. Deep-sea mining in international waters is a unique proposition given that the international seabed is not owned by any state. Instead, it is considered the ‘global commons,’ belonging to all of us, so that any extraction should be justified for the benefit of all humankind. Given deep-sea mining companies also have financially-mandated deadlines, the arguments for it also have to address why there is a supposed urgency. This is especially true given that scientists stress the many unknowns, both about the deep-sea environment itself and the likely cumulative impact of the industry. Over the years, those proposing deep-sea mining have come up with a number of reasons why such mining is necessary and urgent, beyond potential profit. The arguments have evolved to claim that minerals will primarily feed into the energy transition away from fossil fuels. A squat lobster in the deep sea. Image by Schmidt Ocean Institute (CC BY-NC-SA 4.0). As covered by Mongabay, effective counter-arguments have questioned how necessary the specific minerals from deep-sea mining are for the energy transition, including whether ongoing changes in battery technology and demand will negate any estimated…This article was originally published on Mongabay

Globally, about half of drinking water and a quarter of irrigation water comes from under the ground. Yet many coastal sites throughout the world are seeing notable declines in their groundwater levels, putting them at risk of saltwater intrusion, a new study says. The study, published April 14 in the journal Nature Water, found that more than 10% of monitored locations showed a significant years-long decline in groundwater levels, indicating a susceptibility to saltwater intrusion, which can render water unusable. Annika Nolte, a data scientist at the University of Bremen in Germany and lead author of the study, said the results amounted to a “warning” and the work offered a “broad global look at the existing risks” while also identifying “specific regions where we should prioritize management and monitoring.” Sections of a cornfield in the eastern United States.

Earlier this month, state-owned oil company Petroecuador announced a new project involving “hydraulic fracturing” in an oil block in the Ecuadorian Amazon. As a result, some observers spoke out against the environmental risks of high-volume shale “fracking,” in which water and chemicals are injected at high pressures into the tight bedrock to release trapped oil and gas. Shale fracking tends to cause air pollution, uses high quantities of water, and can result in contamination that creates public health risks for surrounding communities. But while “hydraulic fracturing” and shale “fracking” involve similar processes, they’re carried out at entirely different intensities, with different designs, the observers later said. The two terms are often used interchangeably, and the government didn’t explain the distinction or follow up when the groups asked for clarification, they said. “It’s striking because, for us, one of the concerns is the lack of information associated with this announcement,” Sebastián Valdivieso, Ecuador country director for the Wildlife Conservation Society (WCS), told Mongabay. The announcement concerned oil in Block 57, also known as the Shushufindi Libertador block, located in Sucumbíos province, which is largely covered by Amazonian rainforest. New drilling there would yield 930 barrels a day, extracted with the help of service provider Chuanqing Drilling Engineering Corporation (CCDC), a subsidiary of China National Petroleum Corporation. In its announcement, Petroecuador said it was the first time in the country’s history that hydraulic fracturing would be used on subsurface limestone, where those kinds of operations aren’t usually carried out.

Avian vampire flies (Philornis downsi) were not discovered in the Galápagos Islands for almost three decades after they were thought to have arrived from mainland Ecuador in the 1960s. Even then, the first were found by accident. Birgit Fessl, a landbird ecologist, was surveying for native species on the island of Santa Cruz in 1997 when she reached into the branches of a tree to take down the huge, domed nest of a woodpecker finch. Inside was a surprise. “We found one dying chick, another dead one which just looked sucked dry and 20 large maggots full of blood,” said Fessl, who now leads the Charles Darwin Foundation’s Landbird Conservation program. “I was stunned — the first dead baby in my hands. Then I realized it wasn’t an accident: It was everywhere,” she told Mongabay over a WhatsApp call. Across each of the Galapagos’ human-inhabited islands, vampire flies had already wrought havoc, killing some chicks in nests they infiltrated and leaving others maimed for life. “But it went unseen because people didn’t really know what to look for.” Around the world, more than 37,000 invasive species have been introduced to new environments. Many of these cause suffering, from vampire flies maiming finches to yellow crazy ants (Anoplolepis gracilipes) spraying acid at the eyes of shrikes (Laniidae) on Minami-Daitō Island, Japan, and Australian quolls (Dasyurus) bleeding from the nose after eating toxic cane toads (Rhinella marina). But none of these are measured by the current global standard for assessing the impact…This article was originally published on Mongabay

For many Nigerian women, access to sanitary pads remains a challenge. Even those who can obtain them, the prevalence of single-use menstrual products creates problems of its own. They contain plastics and chemicals and are not eco-friendly generating large amounts of waste. After learning that many traditional sanitary pads used contain up to 90% plastic and can take hundreds of years to decompose, Nigerian teenager Raheema Auwal-Panti saw an opportunity to support women while helping the environment. The 15-year-old decided to use low-grade agricultural waste to make sanitary pads. She was motivated by a desire “to sweep up plastic pollution” in Nigeria. “[Even] if no one does something about it, I could do something about it,” said Auwal-Panti, who hails from Minna, the capital of Niger state in Nigeria. She founded ‘PantiPads’ in 2025. Auwal-Panti’s project was selected in a shortlist of 35 global teams for the 2026 Earth Prize, organized by the Earth Foundation, a Switzerland-based nonprofit that empowers, educates and inspires young people to tackle environmental challenges. In northern Nigeria, cassava processing generates significant agricultural waste, which poses environmental risks, particularly to soil quality. The waste includes solid and liquid components, such as cassava peelings, dried with non-dried banana leaves and corn husks. The biomass-rich waste, if poorly managed, can lead to environmental degradation, including organic pollution of water bodies and soil contamination. “Using these wastes to develop eco-friendly pads is currently helping to address menstrual stigma which remains a significant public health challenge that affects girls’ education and overall well-being…This article was originally published on Mongabay

When it comes to decoding camera-trap images, artificial intelligence has become all the rage, especially for terrestrial animals, or those that dwell on the ground. But for more evasive species living high up in trees, the technology is still lacking. A newly developed AI model aims to fill that gap. TropiCam-AI was developed to detect and identify arboreal, or tree-dwelling, species in a part of the world where they abound: the tropical forests of the Americas. Scientists built the model to address the voids that exist in identifying arboreal mammals and birds. “We set up TropiCam-AI with the objective of developing a tool that is specifically meant for neotropical camera-trapping surveys targeting the canopy,” Andrea Zampetti, lead author of the study and Ph.D. candidate in animal biology at the Sapienza University of Rome, told Mongabay in a video interview. Zampetti’s work was done in collaboration with the TROPECOLNET project at the National Museum of Natural Sciences in Madrid, led by Ana Benítez-López. Arboreal species play a key role in ecosystems. They serve as important seed dispersers, with studies finding that primates, small mammals and birds consume up to 90% of plant species in tropical rainforests. However, these are tree-dependent species that, by their very nature, are especially threatened by deforestation, underscoring the need to study, track and monitor them for conservation purposes. A study published earlier this year by Zampetti and colleagues notes that “arboreal camera trapping remains severely underrepresented compared to AI trained on terrestrial images.” AI models for…This article was originally published on Mongabay

The clock is ticking in Brussels. By June 1, the European Commission, the bloc’s executive body, is set to receive feedback on its proposal to remove leather, hides and skins from the EU’s Deforestation Regulation (EUDR). Officials, however, are trying to push this amendment even after the commission’s own research confirmed that cattle hides also drive forest loss, a Mongabay analysis shows. According to the commission’s Staff Working Document, research designed to support proposed regulations, leather can be associated with up to 390 square kilometers (149 square miles) of deforestation per year. That area is roughly twice the size of the city of Pisa, in the heart of Italy’s leather production and trade. This means that bovine hides could account for up to 17% of the total 2,280 km2 (880 mi2) deforestation risk linked to all commodities covered by the new regulation. Although the evidence is part of the documentation, the commission decided to ignore it and balance out “quantitative and qualitative considerations,” it said in the document. The commission’s Staff Working Document was published May 4, alongside a delegated act, as part of a proposed simplification package Brussels is putting forward ahead of the EUDR being enacted at the end of the year. After the public consultation, the commission could formally adopt the draft delegated act. Then the European Parliament and the Council of the European Union generally have two months to object. If they don’t, the changes will automatically be enacted. In its working documentation, the commission argues…This article was originally published on Mongabay

JAKARTA — More than a decade after the palm oil industry embraced a pledge to not deforest, clear tropical peatlands, or use exploitative practices, policies to that end now cover most of the global palm oil trade, as major traders, refiners and consumer brands have pledged to keep deforestation-linked palm oil out of their supply chains. However, deforestation linked to palm oil continues, particularly in Indonesia, the world’s largest producer of the commodity. Satellite analysis by forest-mapping initiative TheTreeMap shows 31,073 hectares (76,783 acres) of forest were cleared for palm oil in Indonesia in 2025, slightly higher than the 30,956 hectares (76,494 acres) recorded in 2024 — highlighting persistent gaps in how the industry enforces its zero-deforestation pledges. In some cases, palm oil from newly cleared land still enters supply chains that companies describe as deforestation-free. “No Deforestation, No Peat, No Exploitation” (NDPE) policies aim to eliminate three major sources of harm in palm oil production: clearing natural forests, developing plantations on carbon-rich peatlands, and exploiting workers or local communities. By 2020, these commitments covered roughly 83% of palm oil refinery capacity in Indonesia and Malaysia, the world’s main producing region. In recent years, companies have also built systems to enforce these pledges. Many now publish grievance mechanisms where violations can be reported, while third-party monitoring groups use satellite imagery to track forest loss and flag suspicious activity. Large-scale corporate deforestation in Indonesia has fallen compared to the mid-2010s, when some plantation companies were clearing vast areas of rainforest. Deforestation for…This article was originally published on Mongabay

One of the first things H.S. Sathya Chandra Sagar noticed in Gola Rainforest National Park was its profusion of sound. Standing amid the tallest trees he’d ever seen, Sagar could hear the calls of countless birds, the hoot of primates, and in the distance, drumming: chimpanzees, beating fists and sticks on tree roots to check in with faraway friends. The din was a chorus of good news. Sagar, a conservation biologist, had traveled to the Sierra Leone national park as part of his Ph.D. research at the University of Wisconsin-Madison in the U.S. to try and figure out if economic measures aimed at conserving carbon in the Gola Rainforest also helped protect its animal biodiversity. In a study published in Conservation Science and Practice, Sagar and his co-authors find that its noisy soundscape suggests that it does. “We see that if it’s done well, carbon financing initiatives do have the capability to protect both biodiversity, beyond just habitat, and carbon markets,” Sagar says. Gola Rainforest National Park is one of the largest remaining portions of the Upper Guinean Tropical Rainforest, which once covered some 700,000 square kilometers (about 270,000 square miles) of West Africa. After a century of mining and logging, and a devastating civil war in the 1990s, Sierra Leone protected 700 km2 (270 mi2) of this forest that remained within its borders in 2010. In 2012, Sierra Leone established the Gola REDD+ project, a framework created through the United Nations Reducing Emissions from Deforestation and forest Degradation (REDD+)…This article was originally published on Mongabay

This is part 1 of a two-part series examining the U.S.’s efforts to begin deep-sea mining in federal waters. Part 1 explores the process behind proposed lease sales in U.S. federal waters and reactions to those plans. Part 2, to be published soon, will examine the regulations that would govern the industry. The U.S. agency responsible for overseeing deep-sea mining in federal waters is preparing to auction off seabed blocks within months — a step that could kick-start commercial-scale deep-sea mining and make the U.S. one of the first countries to allow it. Deep-sea mining has not yet begun anywhere in the world. Opponents say it could cause widespread and irreversible damage to the marine environment if it begins, while supporters say it could provide an important source of critical minerals. In a budgetary document released in April 2026, the U.S. Department of the Interior (DOI) indicated it intends to hold at least three offshore lease sales during the 2026 and 2027 fiscal years. The lease sales will take place through competitive auctions, providing a pathway for winning companies to gain exclusive rights to explore and exploit minerals in designated tracts of seabed. The first sale is slated for the federal waters of American Samoa in August 2026; a second in the Commonwealth of the Northern Mariana Islands (CNMI) in November 2026; and a third in Alaska in 2027. A spokesperson for the Bureau of Ocean Energy Management (BOEM), the U.S. agency currently responsible for the development of offshore energy…This article was originally published on Mongabay

KATHMANDU — As Nepal expands highways, railways and power lines across the country, a new nationwide study warns the infrastructure boom is cutting through habitats and movement routes used by threatened species. The mapping study, published by WWF Nepal, identifies 515 “biodiversity important areas” (BIAs) and finds extensive overlap between those landscapes and the sites of existing or planned infrastructure projects. A total of 6,529 kilometers (4,057 miles) of roads and 4,862 km (3,021 mi) of power lines already pass through these areas. Nearly a quarter of Nepal’s proposed railway network could also cut across them once completed. The findings sharpen a growing policy dilemma for Nepal: how to build the transportation and power networks needed for economic growth without fragmenting the forests, wetlands and rivers that wildlife depend on, especially outside the country’s protected areas. The BIAs identified in the report fall under 11 categories, including key biodiversity areas, important bird areas, Ramsar wetlands, forest conservation areas, and ecological corridors. Together, they form habitats and ecological zones that allow wildlife to move, breed and survive. Jhamak Bahadur Karki, a former chief warden at Chitwan National Park and faculty member at the Kathmandu Forestry College, who wasn’t involved in the study, said its significance lies in the fact that it highlights biodiversity important areas outside of Nepal’s national parks and wildlife reserves. “The study is eye-opening,” Karki said. “It clearly shows why Nepal needs to pay attention to biodiversity important areas that lie outside protected areas.” Distribution of all infrastructure…This article was originally published on Mongabay

KAMPALA — In the hills and trading centers of western Uganda, bordering the Democratic Republic of Congo, authorities are racing to limit the spread of Bundibugyo ebolavirus, a rare species of Ebola for which there is currently no vaccine or cure. The number of suspected cases in the DRC is fast approaching 1,000, with Uganda reporting seven cases, as of May 25. The first cluster of cases of the ongoing outbreak was detected in early May in Ituri province in the DRC, which shares a border with Uganda. The close community and economic ties between people residing on both sides of the border has complicated efforts to contain the outbreak, with Uganda taking measures to stem the flow of people. The Ebola virus driving the current outbreak is named for Uganda’s Bundibugyo district, where it was first detected almost two decades ago. (International health bodies including the World Health Organization have since moved away from naming disease-causing pathogens after places, citing stigmatization.) Most Ebola outbreaks to date have been caused by the Zaire ebolavirus, which also drove the 2014-2016 epidemic centered on West Africa. The Bundibugyo ebolavirus has been linked to two outbreaks in the past. The second outbreak emerged in the DRC in 2012 remained limited to the country, before subsiding later that year. This time may be different, since cases have emerged in Uganda, and the risk of regional spread is high. On May 23, the Africa Centres for Disease Control and Prevention (Africa CDC) identified 10 other…This article was originally published on Mongabay

TANJUNG BUNGAH, Malaysia — When Yap Jo Leen was tracking dusky langurs in the forests of Penang for her master’s degree in 2016, she watched a langur they called Towkay Soh — Hokkien for “lady boss” — get hit by a car while trying to cross a busy coastal road. Dazed, the langur managed to get back on its feet and retreat into a tree while Yap and her colleagues blocked traffic. As Towkay Soh recuperated over the next few days, the langur group’s empathy for each other was on full display, Yap says. “Female individuals, they would approach her and groom her and even try to make her feel better,” Yap says. “I always believe that the primates, humans and monkeys, we all share a similarity, which is connection.” Two dusky langurs called “Kim” (left) and “Sunny” (right) named by the Langur Project Penang at a playground near a residential area in the Tanjung Bungah area of George Town on Malaysia’s Penang Island. For Malaysia’s endangered dusky langurs, recognizable by the characteristic white “eye masks” that stand out against their black fur, survival increasingly depends on manmade crossings across urban landscapes and the work of “citizen scientists”. Image by Mohd Rasfan / AFP. Other langurs weren’t so lucky. From 2016 to 2018, Yap recorded eight langur roadkill deaths in the same area. So, in 2019, Yap and her collaborators built an artificial canopy bridge over the road, made from old fire hoses. Since then, they’ve recorded zero langur roadkill…This article was originally published on Mongabay
