Marine heat waves and raw sewage combine to put human health at risk
- Climate change is fueling an increasing number of marine heat waves across the globe.
- When this intensifying heat is coupled with pollution — especially sewage, nitrogen fertilizer agricultural runoff, wildfire soot and possibly plastics — waterborne bacterial pathogens can multiply, raising human health concerns.
- These connections are exemplified in the escalating spread of Vibrio, a group of naturally occurring bacteria whose numbers are multiplying and undergoing global distribution shifts due to complex relationships between marine heat waves and pollution.
- Vibrio infections can range in severity but can result in sickness and death. One notorious Vibrio species is known as the flesh-eating bacteria; another causes cholera.

Earth’s freshwater fish face harsh new climate challenges, researchers warn
- Climate change is rapidly altering freshwater ecosystems — raising temperatures, altering flood pulses and oxygen levels — and driving complex, region-specific changes in how fish grow, migrate and survive.
- Long-term U.S. data show sharp declines in cold-water fish as streams and lakes warm, while warm-water species gain only slightly. Some cold-adapted species are now disappearing as deep waters cease being a cold refuge.
- From Africa to the Arctic, impacts are emerging, including stronger lake stratification, declining fisheries and rivers turning orange as thawing permafrost releases toxic metals. Declining freshwater fisheries increasingly put food security at risk, especially affecting diets and health in traditional and Indigenous communities.
- Scientists say management and conservation techniques rooted in past conditions no longer work. New approaches must anticipate shifting baselines as climate change rapidly accelerates.

Collapses of Amazon riverbanks threaten communities and shipping routes
- Extreme droughts, human interventions and growing boat traffic are contributing to riverbank collapses that endanger riverside communities in the Brazilian Amazon.
- Four public river ports in Amazonas state have been damaged by riverbank collapses in the past decade, prompting concerns about the safety of Amazon port infrastructure.
- Brazil’s Federal Public Ministry is investigating alleged failures to prevent collapses at regional ports that connect riverside communities and provide access to essential services.

Nepal Indigenous leaders refile writ petition against hydropower project
- In 2024, Indigenous Bhote-Lhomi Singsa people filed a writ petition against a hydropower project expressing concerns over what they say is a flawed EIA, forged signatures and community rights violations in Lungbasamba landscape, a biocultural heritage home to endangered flora and fauna.
- More than a year since the petition, leaders say the construction work has progressed in the absence of an interim order from the court to halt the construction, which has impacted their livelihoods, supported by farming, yak herding and trade in medicinal herbs.
- Demanding the project’s cancellation with an interim order to halt the ongoing construction activities, and to declare the EIA void, leaders filed another petition in November.
- Given the criticisms over the project and impacts outlined by the EIA report, the company says it still looks forward to the project, which is set to be completed in 2028.

With a target on their bellies, can California’s sturgeon survive?
- California’s green sturgeon and white sturgeon face numerous threats from dams, harmful algal blooms and overfishing.
- White sturgeon are highly prized for their eggs, which are made into caviar.
- Their numbers have dropped so precipitously that they’re now being considered for protection under the California Endangered Species Act.
- The state banned commercial sturgeon fishing in 1954, but the amount of poaching and caviar trafficking is unknown, and there have been cases linked to criminal networks involved in other illegal activities.

New mapping reveals hidden mining boom in Laos that threatens the Mekong
- Satellite analysis has identified 517 suspected riverbank mines in Laos, many likely illegal, with clusters along key Mekong tributaries, raising fears of widespread, unmonitored contamination.
- Officials in Attapeu province confirmed illegal mining remains pervasive despite crackdowns, with most operations missing from official records and many linked to Vietnamese or Chinese supply chains.
- The mining surge, including gold and rare earth extraction, poses major risks to ecosystems and communities in the Mekong Basin, where water testing capacity is weak and signs of declining fish populations and polluted rivers are emerging.
- Researchers say Mekong countries must coordinate regionally and engage China, the main importer of the region’s mining output, while strengthening enforcement and environmental oversight to address a rapidly expanding, largely unregulated mining sector.

In Chocó, river defenders say race for energy transition threatens lifelines
- Colombia is looking to accelerate its energy transition amid growing international demand for strategic minerals. But activists from El Carmen de Atrato in Chocó, western Colombia, allege that El Roble, the country’s only active copper mine, is harming the environment and local community.
- The Atrato River, which flows beneath El Roble, was granted constitutional rights in 2016, yet activists raise long-standing concerns over water pollution, tailings dam risks and alleged failures to meet conservation commitments in the area surrounding the mine.
- Critics say the mine has been allowed to operate under antiquated environmental regulation, with a modern environmental licence still under review.
- El Roble rejects all allegations, stating it is a responsible business that complies with environmental regulations. The company says it is the primary source of employment in El Carmen and points to its track record of local investment and community projects.

Scientists chart a new source, and length, for Africa’s famous Zambezi River
- Historically, the Zambezi River in Southern Africa was believed to begin its journey at a spring in northwestern Zambia.
- A new study suggests the river actually starts off in a shallow depression in Angola’s southern highlands, at the source of a river called the Lungwebungu, giving the Zambezi a new total length of 3,421 km (2,126 mi), or 342 km (213 mi) longer than previously thought.
- The Lungwebungu and several other Angolan rivers contribute about 70% of the water reaching Victoria Falls, making them critical to the long-term health of the Zambezi and the people and wildlife who depend on it.
- The study highlights the importance of protecting the Upper Zambezi Basin, where another recent study recorded significant forest loss over the past three decades.

Forest loss, fires and invasions soar in Nicaraguan wildlife refuge, watchdog warns
- The Rio San Juan Wildlife Refuge in southern Nicaragua is part of the best-preserved humid forest in Central America, but illegal invasions, deforestation and mining have destroyed nearly a third of this protected area in less than 10 years, according to an NGO.
- In a report, Fundación del Río alleges the invasions are encouraged by officials linked to the country’s ruling Sandinista National Liberation Front, as well as people close to President Daniel Ortega and his wife.
- The report warns of an increase in the trafficking of mercury and cyanide, typically used in illegal gold mining, which it says endangers the rivers in the region.
- It also says the invasions are displacing the Indigenous Rama people and Afro-descendant Kriol people who have long helped preserved the wildlife refuge.

New riverside lake in Nepal wins hearts, but faces government opposition
- The Bagmati Lake (Bharat Taal), constructed recently in Nepal’s southern Sarlahi district, attracts Nepali and Indian tourists with recreational activities, generating revenue, employment and cross-border tourism.
- The lake, which may have helped improve groundwater levels, soil moisture and crop yields in surrounding areas, has provided habitat for migratory birds.
- However, the fate of the lake hangs in the balance as the country’s anti-corruption court looks into alleged corruption and the lack of environmental compliance during its construction.

Bird diversity drops in human-dominated habitats, Nepal study suggests
- Areas dominated by humans are home to fewer species, with similar ecosystem function and proximity in the evolutionary family tree, a recent study in Nepal’s southern plains suggests.
- Human activities act like a filter, letting only certain birds survive. Even natural areas show signs of such filtering when logging and hunting remove sensitive species, leaving behind only closely related groups of birds that are resilient and adaptable.
- A mosaic landscape provides more “homes” and more ecological roles for birds, helping them survive even amid human disturbances.

Brazil nut hauling effort gets easier with zip lines and ‘Amazon Waze’
- Researchers are developing solutions to help Brazil nut collectors in the Amazon Rainforest reduce the physical toll of the trade.
- These include zip lines to haul heavy sacks across difficult terrain, and ergonomic baskets to reduce back strain while picking up the nut pods.
- These new technologies could encourage Indigenous youths to continue the practice, a crucial step for sustaining local communities who keep the Amazon standing.
- These advances are part of Brazil’s national push for a bioeconomy, a model designed to generate economic growth and social inclusion while protecting the rainforest.

Toxic runoff from politically linked gold mine poisons Cambodian rivers, communities
- Communities along Cambodia’s O’Ta Bouk River are experiencing severe water contamination, skin ailments and the collapse of fish stocks, which they blame on an unregulated gold mine operating upstream inside Virachey National Park.
- Satellite imagery analysis shows more than 2,400 mining sites across Mekong river basins — including alluvial and heap-leach gold mines — whose toxic runoff threatens rivers, floodplains, farmland, wildlife and millions of downstream residents.
- Communities downstream of the gold mine told Mongabay that authorities have failed to act on the problem, despite multiple indicators suggesting the pollution of the river is linked to mining activity.
- Evidence points to mining operations linked to tycoon Try Pheap, allegedly operating illegally and with political protection, leaving communities fearful for their health, livelihoods and food security as contamination spreads through the Mekong Basin.

Lesotho communities allege greenwashing by project transferring water to South Africa
- The Lesotho Highlands Water Project (LHWP), a scheme to transfer water from Lesotho’s river systems to neighboring South Africa, also aims to provide hydropower to Lesotho’s people.
- However, complainants from communities impacted and displaced by the complex of dams, water channels, feeder roads, and bridges accuse the developers of promoting the LHWP as a climate mitigation project and ignoring its impacts on their livelihoods and the environment, and call it “greenwashing.”
- The project is degrading the environment, polluting water streams used by residents, destroying cultivable land used to grow food crops, eating into forests, and reducing access to pastures, according to the complaint filed with the African Development Bank (AfDB), which is partly financing the LHWP.
- “We are not just being denied benefits from the project, we are suffering harm from it,” the complaint says.

Makassar women press for water as taps and wells run dry in sweltering Indonesian city
- Located on the coast of Sulawesi Island’s largest city, Makassar, Tallo ward endures high water stress and contamination of local sources with heavy metals and other pollutants.
- Water stress is a well-documented driver of gender-based violence around the world, with extensive correlation established by numerous research studies, and causation in many circumstances.
- In Makassar, women are commonly responsible for ensuring local households are supplied with water, which typically involves hauling more than two dozen plastic containers of water across town.
- In response to these challenges, a grassroots women-led organization has entered direct talks with local political leaders and the municipal water company in a bid to improve access to water for consumption and sanitation.

Photos: Drones help First Nations track down cold-water havens for salmon amid warming
- Indigenous fisheries association and river guardians, representing several Mi’kmaq nations in eastern Canada, have launched a drone-based thermal-mapping campaign to locate and protect cold-water refuges vital for threatened Atlantic salmon.
- Warming temperatures are pushing the Atlantic salmon beyond their ideal thermal tolerance, compounding existing pressures on the species, such as overfishing.
- Warming waters and declining river flows during droughts are impacting both the fisheries and the cultural lifeblood of Mi’kmaq society.
- Indigenous river guardians hope the project will pre-emptively shield cool-water habitats before key spawning and migration corridors become unviable.

The price of gold: In Venezuela, mining threatens Indigenous Pemón
- Across southern Venezuela, Indigenous communities have been drawn into mining for gold as their traditional way of life has been disturbed and they lack other economic opportunities.
- Armed groups and a push for extractives have turned the Imataca Forest Reserve in the state of Bolivar into a mining hotspot, sources tell Mongabay, boosting deforestation and river pollution and destroying the livelihoods of Indigenous Pemón families.
- In Canaima National Park, the collapse of tourism and the COVID-19 pandemic have pushed communities into mining. Many operations in the park are run by Pemón, who own rafts, employ local workers and partner with external financiers providing machinery and fuel in exchange for a share of the gold.
- In theory, Venezuela legally guarantees land rights for Indigenous people and requires consultation on extractive projects, but communities denounce a lack of consultation, with both legal and illegal mining encroaching on their territories.

Healthy rivers, healthy people: A Brazil project links human & ecosystem well-being
- A night fishing trip 30 years ago showed Brazilian public health doctor Apolo Heringer the meaning of health: a clean river full of fish — a notion that inspired the Manuelzão Project to restore the Velhas River Basin in southeastern Brazil.
- The basin includes Belo Horizonte Metropolitan Region (BHMR), capital of Minas Gerais, the third-largest metropolitan region in Brazil and home to approximately 5.7 million people in 34 cities; here, the combination of high population density, inadequate urban planning and lack of infrastructure has damaged the rivers that cross the region.
- After sewage treatment plants began operating in the area, fish started returning to the waters; the dorado (Salminus franciscanus) was chosen as an indicator of good water quality since it needs a lot of oxygen to survive and polluted waters have low oxygen levels.
- Connections between the river, its health and people’s understanding are crucial to the Manuelzão Project and its goals for collective health.

India’s Ganga River drying at unprecedented levels
The Ganga River, which sustains the lives of at least 600 million people, is facing its worst dry spell and lowest streamflow in 1,300 years, according to a recent study, reports Mongabay India’s Simrin Sirur. Researchers extrapolated the Ganga’s water levels going back to the year 700 C.E. using a combination of paleoclimatic and historical […]

Thai agri giant CPF sues activist over claims linking it to invasive fish outbreak
- The head of a Thai NGO focused on agricultural monitoring and food sovereignty is being sued by agribusiness giant Charoen Pokphand Foods (CPF) for alleging the firm is linked to the outbreak of an invasive fish species in Thailand’s waterways.
- The lawsuit has been slammed as a SLAPP (strategic lawsuit against public participation) and a tactic to divert attention away from containing the outbreak and identifying the source and parties responsible.
- The blackchin tilapia has spread to at least 19 provinces, where it outcompetes wild and commercially viable aquatic species, disturbing ecosystems and devastating farmers’ livelihoods.
- The case comes as Thailand awaits public hearing of new anti-SLAPP regulations aimed at curbing judicial harassment.

Belém faces its social and natural demons as host to COP30
- Deforestation and the city’s historic shift from rivers to roads led to a massive influx of people into low-lying baixadas, where 57% of residents lack services, such as sewage, and are highly prone to flooding.
- The lack of trees in one of the Amazon’s most revered cities, especially in poor neighborhoods, contributes to projections that Belém will face 222 days of extreme heat by 2050.
- Experts argue that the infrastructure projects being implemented don’t offer sustainable solutions, reflecting a long-term failure to address Belém’s water and sewage crises.

Rare earth mining expands into Laos, threatening entire Mekong River
- Satellite data show at least 27 new rare earth mines have opened across Laos since 2022, mostly in protected areas and many within the Mekong River Basin, raising transboundary pollution risks for Vietnam and the wider Mekong system.
- Though rare earth mining is banned in Laos, operations — often funded by Chinese investors — continue under local-level permissions, reflecting weak oversight and growing Chinese influence as Laos seeks to boost its resource exports.
- Past incidents of chemical spills and fish die-offs have already harmed communities in northern and northeastern Laos, yet limited press freedom and civic space mean contamination and environmental impacts remain largely unreported and unmonitored.
- Experts warn that a rare earth mining boom could have severe ecological and social consequences, including deforestation, loss of livelihoods, and toxic pollution, with local communities powerless against unregulated mining backed by local elites and foreign capital.

Nickel mining damage near UNESCO site stirs outrage in southern Philippines
- A recent survey by the Davao Oriental provincial government engineering office revealed that a strip mine operating in the province had scraped bare about 200 hectares of forestland.
- After the survey, the provincial governor said the province would order the Pujada nickel mine to cease operations.
- The mine is within 10 kilometers of two protected areas: the Mount Hamiguitan Range Wildlife Sanctuary, a UNESCO World Heritage Site; and the Pujada Bay, a nationally protected seascape.

Negro River study finds genetic damage in fish after oil spill
- Scientists assessed harmful effects on Amazonian fish after a barge capsized in 2013 with approximately 60,000 liters of petroleum asphalt cement in Manaus.
- Although the concentration of the contaminant decreased with rising water levels, the fish continued to exhibit effects of exposure three months after the accident, including DNA damage and neurotoxicity.
- The Negro River’s waters are rich in dissolved organic matter, which may increase the toxicity of the chemical compound.
- This research adds to other studies that attest to the harmful effects of oil on vertebrates, aquatic insects and plants in the Amazon, given the pressure for greater exploration in the region.

More Thai rivers and downstream communities at risk from Myanmar’s rare earth mines
- Satellite data reveal 513 rare earth mining sites across rivers feeding into the Mekong, Salween and Irrawaddy in Myanmar, including 40 new ones in 2025 — far more than previously estimated.
- Toxic runoff from unregulated mines in Shan and Kachin states has polluted rivers flowing into northern Thailand, causing some $40 million in losses to farming, fishing and tourism.
- Communities in the Thai provinces of Chiang Mai and Chiang Rai are struggling with contaminated water and weak government response, prompting grassroots groups to demand testing, clean water sources, and a halt to imports from Myanmar.
- China’s tightening controls and rising demand for rare earths have fueled Myanmar’s mining boom, with conflict and lax oversight allowing environmental destruction and cross-border pollution to spread downstream through Southeast Asia.

A closer look at Peru’s Amazon reveals new mining trends, deforestation
- A new analysis from the Monitoring of the Andes Amazon Program shows differences in mining patterns in the central and northern departments of the country, compared with southern departments like Madre de Dios.
- The mapping analysis is one of the first visualizations of Peru’s mining problem on a nationwide scale.
- The organization called for a better gold traceability system and for small-scale and artisanal mining activities to be subject to stricter environmental oversight.

Indigenous monitoring project helps protect isolated peoples in Colombia’s Amazon
- Indigenous communities neighboring the peoples living in isolation in Colombian Amazon have spent more than a decade helping the latter remain separate from the outside world.
- Members of the Curare-Los Ingleses Indigenous Reserve and of the community of Manacaro use traditional knowledge and technology alike to monitor threats to their territory and to protect nearby communities living in isolation.
- In Manacaro, women take on traditionally masculine roles by patrolling the rivers, collecting data, and safeguarding their neighbors’ lives amid the advance of armed actors and illegal mining.
- Surveillance work has provided evidence of uncontacted peoples, such as the Yuri and Passé ethnic groups, which was fundamental in the federal government’s decision to formally recognize them.

‘We can have abundant rivers and wildlife’: Director of ‘The American Southwest’ on new film
- “The American Southwest” is a new film that explores the importance of the Colorado River in western North America to people and to wildlife.
- Part natural history film, part social documentary, it explores the challenges the Colorado faces as its resources are stretched thin by the demands for cities, energy and agriculture.
- Negotiations over the river’s water after a current agreement expires at the end of 2026 offer an opportunity for more equitable sharing that includes the river itself and long-marginalized representation from the Native tribes who live along the river’s length.
- The film appeared in theaters beginning Sept. 5 and on streaming platforms Oct. 10.

Climate change and aging drains wreak havoc on Kolkata, India
On Sept. 23, the city of Kolkata in eastern India came to a standstill: The capital of West Bengal state received more than 12% of the city’s average annual rainfall in just 24 hours, some 247.5 millimeters (9.7 inches). The subsequent flooding claimed lives and caused extensive property damage. Scientists say climate change has made […]
Cameroon inaugurates controversial dam despite local dissent
- The inauguration of Cameroon’s Nachtigal dam has boosted the country’s electricity supply.
- The dam’s construction has also led to loss of livelihoods for fishers and sand miners on the Sanaga River around the dam site.
- In 2022, these workers received compensation from the dam, but as the full dimensions of their losses emerge, they say this was inadequate.

Turning a stream into a river: Inside India’s Yettinaholé diversion project
- In Karnataka’s Western Ghats, a biodiversity hotspot, a river diversion project is bringing long-term changes to local villages — and the environment.
- The Yettinaholé Integrated Drinking Water Supply Project aims to divert 24 TMC of stormwater from the Yettinahalla and other nearby streams to several dry districts hundreds of kilometers away.
- Village life is also undergoing a series of development changes — as well as an uptick in conflicts with elephants coming from the nearby forests; meanwhile, local fishers wonder how many of the streams they rely on will become part of the diversion project, fearing for the future of their livelihoods.

Satellite data show burst of deforestation in Myanmar rare earth mining hotspots
- The largely unregulated mining of rare earth minerals in Myanmar’s Kachin state is taking a heavy toll on forests, rivers and human health, according to sources and satellite imagery collected by Mongabay.
- From 2018 to 2024, townships where the mining is concentrated lost about 32,720 hectares (80,850 acres) of tree cover in subtropical and moist forests.
- Researchers say all rare earth minerals from Kachin state wind up at magnet manufacturers in China, which supply some of the world’s best-known producers of electric vehicles, wind turbines and electronics.
- Myanmar’s ongoing civil war is a complicating factor in the issue, with the armed group that controls the Kachin mining sites currently renegotiating terms with Chinese companies and authorities that import the elements, while also formulating regulations for rare earth mining. Whether these will meet international standards remains to be seen, sources say.

Largest turtle nest in the world revealed in drone study
Scientists studying the world’s largest river turtles, a South American species that grows to a length of nearly a meter, or 3 feet, have found the largest nesting aggregation ever recorded. Using drones to conduct a population survey in the western Brazilian Amazon, researchers recorded a nesting area of the endangered giant South American river […]

The Yangtze River is one of the busiest inland waterways in the world with 16 major ports. […]
In Brazil’s Pantanal, too many tourists may be the jaguar’s new predator
- Once rare, jaguar sightings in the Pantanal now number more than 1,000 a year, drawing tourists from around the world.
- Ecotourism has transformed jaguars from hunted predators into valuable attractions, boosting local livelihoods.
- But overcrowding, with up to 30 boats surrounding a single animal, risks stressing wildlife and eroding visitor experiences.
- As safaris become increasingly popular, jaguars are getting more habituated to humans, drawing them closer to ranches, where conflicts arise.

Kafue River Transect
From its source in the wetlands near Zambia’s northwestern border, through the industrial zones of the Copperbelt, to where it plunges through a steep gorge toward the Zambezi, the Kafue River sustains some of Southern Africa’s richest ecosystems, vital to communities, wildlife, and energy production. Mongabay contributor Ryan Truscott joined an initiative exploring the river’s […]
Shrinking Mekong megafish underlines risks to the river, study finds
- A new study has found that the Mekong River’s largest freshwater fish are shrinking in size, with critically endangered species like the giant catfish and giant barb now averaging less than half their historical size.
- Researchers analyzed more than 397,000 samples of 257 species across Laos, Cambodia and Vietnam, finding that fish longer than 60 centimeters (2 feet) are shrinking fastest, while smaller species show little change.
- Overfishing, habitat loss, dam construction, sand mining, pollution and climate change are driving the decline, raising fears of collapse in one of the world’s most important inland fisheries.
- Scientists warn the trend mirrors global declines in large freshwater species, such as in the Amazon and Nile basins, but recent discoveries of massive fish like a 300-kg stingray show it’s not too late for recovery if urgent action is taken.

Escalation in tourism, climate change leaves Nepal’s Mustang in fragile state
- The completion of an all-weather road has transformed ‘lower’ Mustang, shifting from a remote trekking hub to a mass tourism destination. Visitor numbers has surged nearly 50% in one year, fueled largely by domestic and Indian Hindu pilgrims.
- Hotels and lodges have mushroomed along fragile riverbanks with weak zoning enforcement. Tourism water demands and usage have led to untreated sewage entering the Kali Gandaki River.
- Once arid, Mustang is now facing monsoon rains as Arabian Sea warming has started to push rain clouds farther north. The August 2023 flood devastated Kagbeni village, highlighting rising risks of flash floods and landslides.
- While tourism provides livelihoods and the energy is largely renewable, locals remain in the flux of economic opportunity and growing climate risks. Researchers call for urgent data, early warning systems and relocation from high-risk zones.

Development banks under fire for backing disputed Nepal hydropower project
- Civil society leaders in Nepal continue to raise concerns about the in-development Tanahu hydropower project in Gandaki province, citing a lack of proper consultation, inadequate compensation for displacement, and environmental impacts.
- Project developer Tanahu Hydropower Limited (THL), a subsidiary of the national electricity utility, says it has completed the consultation process.
- Half of the complaints against hydropower projects in Nepal documented by a rights watchdog are related to the Tanahu project, which receives funding from the Asian Development Bank, European Investment Bank and World Bank.
- Most of Nepal’s electricity is generated through hydropower, and the government plans to expand the country’s generating capacity nearly eightfold to 28,500 megawatts by 2035.

In western Nepal, farmers switch to growing turmeric; elephants stay away
- In western Nepal’s Bardiya district, farmers from marginalized communities are replacing traditional crops with turmeric — a plant elephants avoid — dramatically reducing human-elephant conflict.
- Backed by conservation groups and supported by scientific studies, the community-led shift to turmeric farming offers a replicable model for coexistence.
- The initiative combines traditional knowledge, scientific research and targeted support to turn a long-standing conservation challenge into an opportunity for ecological and economic resilience.

Displaced and dispossessed, Cambodia’s ethnic Cham fishers struggle to survive
- Ethnic Cham fishers in Cambodia say they face repeated evictions from their floating homes, often timed with major events and justified as environmental protection.
- They report unequal treatment by authorities, with harsher crackdowns on their small-scale fishing while larger, illegal operations go unpunished.
- Displacement and enforcement have pushed many into poverty, with little access to alternative livelihoods or support systems.
- Experts and advocates warn that current policies risk erasing Cham culture and call for more equitable, historically informed solutions.

Asia’s longest free-flowing river faces threats of dams and diversions
The Salween River, at around 3,300 kilometers, or 2,000 miles, is Asia’s longest free-flowing river, running from Tibet through Myanmar to the Andaman Sea. But Indigenous groups and communities living along its banks in China, Myanmar and Thailand say they fear hydropower development might cause the river to suffer the same fate as the Mekong […]
Can rainwater-fed ponds revive Bangladesh’s hilly streams?
- Natural streams in Bangladesh’s southeastern Chittagong Hill Tracts are drying up due to climate change and human activities.
- Rainwater harvesting in man-made ponds holds hopes for the revival of streams and could boost local biodiversity.
- The nature-based solution faces obstacles such as lack of resources and structural vulnerability.
- Experts suggest that co-management with the participation of local communities could bring good results to conserve such natural streams in the region.

Sacred sites & cultural practices key to Indonesia fish conservation: Study
- Researchers have found that sacred waters protected by Indigenous traditions are crucial for fish conservation in Indonesia but remain excluded from national conservation frameworks.
- The study highlights how cultural practices have long preserved aquatic biodiversity, urging their integration into official conservation strategies.
- Experts call for deeper anthropological insight and recommend recognizing sacred sites through Indonesia’s Essential Ecosystem Areas to connect traditional and scientific conservation.

Africa’s freshwater fish face a crisis — but solutions are within reach
A new WWF report is sounding the alarm on Africa’s freshwater fish: one in four fish species it assessed is at risk of extinction. These declines threaten not only biodiversity, but also the food security, livelihoods and cultural identity of millions of people who depend on inland fisheries across the continent. Released in the lead-up […]
Bicolored waterberry: The overlooked tree shaping Zambia’s rivers
- The bicolored waterberry (Syzygium guineense subsp. barotsense) is a dominant tree along the Kafue and other major Zambian rivers, where it plays a vital structural and ecological role.
- Though capable of self-pollination, the tree’s flowers attract bees, birds and moths, creating vibrant micro-ecosystems in its canopy.
- While not currently threatened, riparian clearing poses local risks, and the trees’ value to pollinators may offer a path to conservation.

River of giants: Canoe team tracks hippos in one of Africa’s last strongholds
- A team from The Wilderness Project has conducted a survey of hippos along Zambia’s Kafue River, one of the last strongholds of the species in Southern Africa.
- The expedition faced regular close encounters with hippos, which are highly territorial and can be dangerous to people, especially when traveling by boat.
- The team counted nearly 2,400 hippos, most of them along a 350-kilometer (217-mile) stretch of the Kafue within the Kafue National Park and adjoining protected areas, underscoring the park’s conservation importance.
- Despite their ecological significance as ecosystem engineers, hippos remain understudied and increasingly vulnerable to habitat loss and pollution, including upstream mining spills.

Wildlife & tourists on the up in Zambia’s Kafue Park: Q&A with manager Craig Reid
- Zambia’s Kafue National Park, co-managed by Zambia’s Department of National Parks and Wildlife and conservation NGO African Parks, is home to up to 22 different species of antelopes, the highest diversity in Africa, more than 500 species of birds and at least 2,400 hippos in the river from which the park takes its name.
- Park manager Craig Reid says the nine game management areas that provide a buffer zone around the park have been modified in one way or another — including by climate-affected farmers and livestock herders — and illegal hunting also poses a threat to the core zone’s ecological integrity, as does pollution from mining and large settlements upstream.
- But, he says, around 3 million hectares (7.4 million acres) of the GMA buffer remains completely unsettled, and the park and the stretch of the Kafue that runs through it are doing well – more than $4 million worth of fish is sustainably caught within its boundaries every year.
- African Parks plans to introduce as many as 60 black rhinos to Kafue NP in the coming years and has already reestablished a thriving population of Kafue lechwe, a wetlands antelope unique to this landscape.

Canada’s Pacific Coast hit hard by trawling, with limited transparency: Report
- Trawling vessels pursuing fish are damaging marine ecosystems in Canada’s West Coast waters and could be operating illegally in some cases, and yet they work with insufficient transparency, a new NGO report says.
- Nine large trawlers have together trawled swaths of the ocean collectively larger than the size of Ireland since 2009; they have likely trawled in prohibited zones at least 47 times and have disrupted Chinook salmon (Oncorhynchus tshawytscha) migratory routes, which are foraging areas for an endangered population of killer whales (Orcinus orca), the report says.
- A trawling industry group dismissed the NGO’s findings, saying they lacked context and the fishery was very well regulated.
- A Canadian regulatory agency said the fishery was well managed, with strict monitoring and enforcement of rules.

‘Croc on a rock’: How a group of explorers suffers for science
- A team from The Wilderness Project is traversing Zambia’s Kafue River by canoe, collecting ecological data as part of a long-term survey.
- The expedition involves grueling portages over sharp, slippery rocks, close encounters with crocodiles and hippos and physically demanding conditions.
- Researchers gather DNA from fish and invasive crayfish, record nocturnal wildlife sounds and retrace a sampling transect first surveyed the year before.
- Despite the challenges, moments of beauty and wildlife encounters — from elephant herds to misty hornbill flights — punctuate the journey.

A success story at Zambia’s leopard hotspot: Interview with ecologist Chisomo M’hango
- At the Musekese Conservation research station, deep in Zambia’s Kafue National Park, trainee field ecologist Chisomo M’hango analyzes camera trap images of leopards, lions and wild dogs.
- M’hango and colleagues have identified 95 individual leopards, one of the highest densities of this vulnerable species anywhere in Southern Africa.
- The camera traps have caught relatively few lions, likely due to lack of prey in an area where widespread hunting of large antelopes has taken place for decades; M’hango says lion numbers are starting to rise, signaling renewed efforts to prevent poaching in the park and its buffer areas is bearing fruit.
- There are also encouraging signs that populations of wild dogs are recovering, with the single pair monitored soon after Musekese’s research began in 2020 multiplying into three healthy packs of this gregarious endangered carnivore.

From cattle to crayfish, human pressures mount on Zambia’s Kafue River
- A group of scientists paddled the length of Zambia’s Kafue River to document ecological pressures, including invasive species, habitat changes and human encroachment.
- Australian red-clawed crayfish (Cherax quadricarinatus) have infested the river, outcompeting native species, disrupting fisheries and altering fishing practices. The crayfish invasion spans nearly the entire 1,600-kilometer (995-mile) river, traced to an original introduction in 2001.
- Overgrazing and invasive plants like the giant sensitive bush are transforming some riparian zones, threatening biodiversity, including endemic species like the Kafue lechwe (Kobus leche kafuensis).
- Researchers with The Wilderness Project’s Great Spine of Africa project are using standardized field methods to monitor river health and the spread of invasive species to inform future conservation efforts.

Brazil court halts plan to blast 35-km river rock formation hosting endangered species
A federal court in Brazil has blocked the start of planned explosions along a 35-kilometer (22-mile) rock formation called Pedral do Lourenço in the Tocantins River, pausing a major infrastructure project until a judge can inspect the site. The decision suspends the federal government’s attempt to clear the way for large cargo ships to travel […]
Mining spill highlights need to protect Zambia’s vital Kafue River & its fish
- Researchers from The Wilderness Project (TWP) are documenting fish diversity along Zambia’s Kafue River to build a DNA reference library.
- The TWP scientists are collecting fin clippings and environmental DNA to help identify species, including some potentially new to science, without needing to catch them in the future.
- The river, a vital source of food and income for local communities, suffered from major pollution in February when a mine waste dam failed upstream.
- Protected stretches of the river within Kafue National Park offer crucial refuge for fish and other aquatic life, enabling recolonization after environmental shocks like toxic spills.

Bangladeshi village grapples with contaminated water flowing in from India
- A transboundary canal carrying wastewater from upstream India has been impacting the agriculture and aquatic resources of a village in downstream Bangladesh for several decades.
- According to data, the parameters of some essential components of the water, like ‘dissolved oxygen’ and ‘biochemical oxygen demand,’ exceed the tolerable limits of local aquatic species.
- The Bangladeshi government has raised concerns regarding the water pollution with its Indian counterparts and is continuing discussions to solve the crisis as per the bilateral and multilateral agreements.
- The government is also planning to set-up a wastewater treatment plant in the affected area to keep the water quality tolerable for agriculture, livestock use and aquatic species.

Banks bet big on fossil fuels, boosting financing in 2024, report finds
- Bank financing for the fossil fuel sector rose by $162.5 billion in 2024, more than 20% compared to 2023, according to a Rainforest Action Network report.
- Fossil fuel-related financing declined in 2022 and 2023, but in 2024 almost 70% of the 65 banks analyzed increased their funding for companies involved in fossil fuels.
- Experts say the findings demonstrate the limits of voluntary climate-related commitments by the banking industry, with many institutions backsliding on their promises to decarbonize their portfolios.
- They also highlight the importance of government regulation and civic action to address ongoing financial support for fossil fuel infrastructure and expansion.

Sweden needs a rights of nature legal framework (commentary)
- On July 1, the reassessment of Sweden’s hydropower plants will resume under the framework of its national plan.
- This is necessary, a new op-ed argues, because the expansion of hydropower has led to sharply reduced salmon populations, and eels are on the verge of extinction. These species are without rights, yet they have a natural right to exist.
- “Some might object that a river or an eel cannot speak in a courtroom. But there are also humans who lack that ability. In such cases, a legal guardian is appointed. In the same way, nature can be given representatives to act on its behalf in court,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Nicaragua government tied to illegal land invasions in wildlife refuge, documents suggest
- Río San Juan Wildlife Refuge in southeastern Nicaragua has suffered a wave of deforestation in recent years, fueled by land deals that allow settlers to clear the rainforest for farming, mining and cattle ranching.
- Without government support, Indigenous and Afro-descendant communities have patrolled the forests on their own but are overwhelmed by the number of people settling in the area.
- Some residents have crossed the border into Costa Rica due to security concerns.
- Recently, the government also authorized more dredging on the San Juan River, despite losing a previous case about dredging at the International Court of Justice.

In Ecuador’s Amazon, Big Oil exploits Indigenous communities in the absence of the state
- Over the last 30 years, the three companies that have operated Block 10, an oil concession in the central Ecuadorian Amazon, have sought to divide local communities.
- They’ve also promoted practices intended to undermine residents’ autonomy, substituting for the state in providing basic services such as health care and education and creating disputes over job opportunities.
- An investigation by the cross-border project Every Last Drop reveals how Indigenous leaders and organizations are resisting these efforts.

Its absorbing narrative takes the reader to the frontlines of some of Earth’s most embattled […]
Specter of dams and diversion looms over Southeast Asia’s Salween River
- The Salween River, one of Asia’s last free-flowing rivers, supports Indigenous communities and biodiversity across China, Myanmar and Thailand, but faces threats from at least 20 proposed hydropower dams, mainly in Myanmar.
- Myanmar’s postcoup instability has stalled dam construction, though powerful armed groups and foreign investors, particularly from China and Thailand, remain key players in determining the river’s fate.
- The Thai-backed Hatgyi Dam and the Yuam River Diversion Project risk submerging villages, displacing Indigenous Karen communities, and diverting massive amounts of water for agriculture in central Thailand.
- Local resistance, legal challenges and transboundary activism are mounting, with critics calling for permanent protection of the Salween and condemning the exclusion of affected communities from decision-making.

World Bank to finance controversial DRC hydropower project, concerns remain
The World Bank recently approved an initial $250 million in financing for the controversial Inga 3 mega dam project in the Democratic Republic of Congo, a move that worries civil society organizations. Inga 3 has long been planned as part of the Grand Inga hydropower project, a series of dams at Inga Falls on the […]
Rare earth rush in Myanmar blamed for toxic river spillover into Thailand
- Water tests from the Kok and Sai rivers near Thailand’s border with Myanmar have revealed elevated arsenic levels, leading Thai officials to warn citizens to avoid contact with river water.
- The pollution is widely believed to be linked to unregulated mining in Myanmar’s Shan state.
- Extraction of gold in Shan State has surged in the years since the 2021 military coup in Myanmar; more recently, mounting evidence suggests rare earth mining is also expanding across the state.
- Elevated arsenic levels have also been found at testing points in the Mekong, which is fed by both the Kok and Sai rivers.

The Yurok tribe have reclaimed Blue Creek, 138 years after it was taken from them
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. The Yurok tribe of northern California has achieved what once seemed impossible: reclaiming the 19,000-hectare (47,000-acre) watershed of Blue Creek, a cold-water artery vital to salmon survival and tribal identity. This marks the largest land-back conservation deal in California […]
The curse of river dolphin ‘love perfumes’ (cartoon)
Already imperiled by habitat loss, climate change and the recent incidences of droughts in the Amazon, the endangered Amazon River Dolphins have yet another curse cast upon them- the myth that the perfume made from their oil, known locally as pusanga, works as an aphrodisiac. Sold both in local markets and online, this trade threatens an […]
In Nepal, northernmost sighting of Eurasian otter raises hope, concerns
- The northernmost Eurasian otter sighting in Nepal was recorded in the Karnali River, raising hopes for the species’ range expansion. But as the animal was found dead in a fishing net, conservationists highlight challenges to the species’ conservation.
- Researchers emphasize the rarity of such sightings in high-altitude, remote areas like Humla, where otters had been considered cryptic or absent for decades.
- The discovery builds on a series of recent sightings across Nepal, including in urbanized Kathmandu Valley, suggesting a wider distribution than previously known.
- Threats to otters include overfishing, poaching, hydropower projects, sand mining and net entanglement, all of which imperil not just the Eurasian otter but also Nepal’s two other otter species.

In a big win, Yurok Nation reclaims vital creek and watershed to restore major salmon run
- Four dams are now down on the Upper Klamath River in northern California in the largest river restoration project in U.S. history. But a rarely mentioned cold-water creek is essential to restoring health to what was once the third-largest salmon run on the West Coast of North America.
- Blue Creek is located just 25 km (16 mi) from the mouth of the Lower Klamath at the Pacific Ocean. Critically, it’s the first cold-water refuge for migrating salmon that enables the fish to cool down, survive, and move farther upriver to spawn. The dams and logging have damaged this important watershed for decades.
- The Yurok, California’s largest Indigenous tribe, lost ownership of Blue Creek to westward U.S. expansion in the late 1800s. In 2002, a timber company, negotiating with the Yurok, agreed to sell back the 19,000-hectare (47,100-acre) watershed to the tribe.
- It took Western Rivers Conservancy, an Oregon-based NGO, nearly two decades to raise the $60 million needed to buy the watershed. In a historic transition, Blue Creek returns this spring to the Yurok for conservation in its entirety. The tribe considers the watershed a sacred place.

Study shows Vietnam’s ethnic communities’ grapple with hydropower plant impacts
- A recently published study based on fieldwork in northwest Vietnam shows how even small hydropower projects can have a large impact on communities.
- With an increase in small hydropower projects, residents of Bien La commune report loss of farmlands, fishing, local jobs and culture, as well as insufficient compensation.
- While these impacts force the villagers to migrate to other districts in search of jobs, the community women try to revive their culture of traditional textiles and indigo dyeing to preserve their way of life.

Villagers in Sumatra bring ancient forest flavors back to the table
- Women living around the 7th-century Muaro Jambi temple complex in Sumatra, Indonesia, have revived ancient ingredients and cooking techniques to serve one-of-a-kind meals to visitors.
- Their dishes are inspired by the plants and animals depicted on the bas-reliefs of another ancient Buddhist site: Borobudur in Java.
- The ancient menu has proved popular both among visitors and locals, who are rediscovering their agrobiodiverse heritage.
- The women have nurtured an ancient food forest and garden in Muaro Jambi to conserve the diverse wild plants and varieties in their menus.

Mining company returns to haunt Thailand’s Karen communities as resistance mounts
- A long-dormant fluorite mine is being reopened in northern Thailand, but the ethnically Karen communities that live in Mae Hong Son province’s Mae La Noi district are staunchly resisting the return of the mining company.
- Universal Mining, a Thai company, aimed to reopen its fluorite mine in 2021 following an injection of Chinese investments, but so far has failed to secure the environmental impact assessment needed to recommence mining operations in Mae La Noi.
- Experts warn that Universal Mining may be able to find a way around the environmental regulations as the Thai government has earmarked parts of Mae La Noi for extraction in its national mining strategy.
- According to rights advocates, the conflict brewing between the mining company and the Karen communities is a reflection of limited rights Thailand gives its Indigenous People.

Brazil set to blast 35 km river rock formation for new Amazon shipping route
- The Brazilian environmental agency, IBAMA, approved a license to blast a natural rock barrier on the Tocantins River in Pará state to enable boats to pass during the dry season, as part of wider efforts to build a massive waterway for commodities.
- Federal prosecutors requested the suspension of the license due to missing studies and other issues.
- A federal court stated that the proposed blasting will have a limited and controlled impact, asserting there are no Indigenous, Quilombola (Afro-Brazilian) or riverine communities living in that section of the Tocantins River — a claim that advocates say is inaccurate.
- Rock removal will impact endangered fish, Amazon turtles and the Araguaia river dolphin, which is found only in this region and feeds on fish that spawn in Pedral do Lourenço.

In Pakistan, desert irrigation plans spark protests & fears among Sindh farmers
- In Pakistan, thousands of protesters have fought against the Cholistan Canal Project, which would divert water from the Indus River to irrigate millions of hectares of desert for corporate farming.
- Opponents say the project would threaten local desert species and leave small-scale farmers and fishers in Sindh province without the water they need; this comes on top of an existing water shortage in the region.
- Water has been one of the region’s most contentious issues, dating back decades and causing a rift between Sindh province and the Federation of Pakistan; now, the future of Pakistan’s water is even more uncertain since India suspended the Indus Waters Treaty of 1960, which governs shared waters between the two countries.

Future of Mexican communal land in limbo as mining company overstays agreement
- Canadian mining company Equinox Gold has failed to implement a closure process after its land use and social-cooperation agreement with the Carrizalillo ejido in Mexico’s Guerrero state ended on March 31.
- It instead announced the indefinite suspension of its Los Filos mine, which the country’s agrarian attorney and legal experts say is not permitted in Mexico.
- Prior to the termination date, representatives of the ejido told Mongabay the company carried out a smear campaign to pressure them into signing a renegotiation proposal which they rejected because of its unfair conditions.
- Meanwhile, members of the ejido who rely on rent payments from the company to survive, have not received any compensation from the company and cannot return to their agrarian way of life because the mine occupies most of their land and the few available areas are contaminated.

Central Java villages take fast fashion to the cleaners at Indonesia’s Supreme Court
- Indonesia’s Supreme Court recently confirmed the bankruptcy of the country’s largest textile group, Sritex, which made garments for global fast fashion retailers like H&M.
- The court also awarded damages to 185 people in Central Java province who had filed a class action suit against a Sritex subsidiary over toxic gas leaks and river pollution.
- More than 10,000 Sritex workers lost their jobs as the heavily indebted firm collapsed, but local residents say the environment has showed signs of recovery since the subsidiary stopped producing synthetic fibers near Java’s longest river, the Bengawan Solo.

Antibiotic pollution widespread in world’s rivers, study finds
Nearly a third of all antibiotics that people consume end up in the world’s rivers, a new study finds. This could potentially harm aquatic life and impact human health by promoting drug resistance, researchers say. Antibiotics, critical for treating various bacterial infections, are widely consumed by people, livestock and aquaculture fish, but the drugs are […]
How manatees won over an entire village
BARRA DO MAMANGUAPE — Brazil. It’s hard to imagine today, but manatees were once hunted and eaten. These gentle sea mammals were considered a delicacy in Brazil, with their meat consumed by local fishermen and their skin and oil exported to Europe during colonial times. This exploitation pushed the species to the brink of extinction. […]
Dredging and pollution threaten fishing in the Niger River
- Some fishers in Bamako, Mali’s capital, are raising concerns about dredging of the Niger River in search of gold.
- They say the combination of dredging and increasing plastic pollution is causing fish stocks to decline.

Meet the Nepali lawyers defending nature one case at a time
- Lawyers in Nepal are increasingly turning to public interest litigation to demand accountability and stronger enforcement of environmental laws.
- They have filed public interest cases targeting issues like air pollution, deforestation, illegal quarrying and the misuse of protected areas.
- Their efforts have led to landmark rulings by the Supreme Court, including directives for better regulation and enforcement of existing laws. However, many of these rulings remain unimplemented due to government inaction and bureaucratic delay.
- Critics caution that while litigation is a powerful tool, it must be used judiciously, and that civil society must also mobilize to ensure environmental justice beyond the courtroom.

Amazon people brace for a drier future along the endangered Madeira River
- The Madeira River, the largest tributary of the Amazon, has been losing water flow over the last 20 years while facing severe droughts.
- The water drop is worrying the local population, whose livelihoods depend on balanced water bodies for small-scale agriculture, wild fruit extractives, fishing and transportation.

Armed groups and junta profit as toxic mines devour southern Myanmar
- Since Myanmar’s 2021 coup, lead mining in the country’s southern Tanintharyi region has exploded, with the number of mining sites more than doubling as lawlessness enables rapid expansion.
- The environmental impact has been severe, with polluted rivers, dying crops, and communities losing access to clean water.
- Armed groups and junta officials profit from the boom by collecting bribes and taxes, turning mining into a revenue source across all control zones.
- Environmentalists warn that without immediate action and sustainable planning, the region’s ecosystems and natural resources may be permanently lost.

Vital Mekong fish corridors tracked for first time, but funding cuts threaten future research
- By implanting fish with small electronic transmitters, researchers were able to track key migration corridors in the Mekong River.
- The findings underscore the threat that dozens of planned dams along the Mekong will cut off these vital migratory paths.
- The study, which the lead author describes as a “pilot effort,” was funded by USAID; the funding gap caused by the U.S. foreign aid freeze leaves the future of such research in question.

Floods devastate normally arid parts of Australia’s Queensland

Groundwater overuse puts Brazil’s river flow at risk, study finds
- A recent study reveals the potential risk of river water flowing underground in Brazil due to high groundwater extraction, which could lead to losses in streamflow.
- Researchers found a correlation between groundwater use and river flow reductions, particularly in dryland areas.
- Overexploitation of groundwater could severely affect Brazil’s agriculture, energy production, and ecosystems, with illegal and unregistered wells likely contributing to the problem.
- Experts stress the importance of improving water resource management, with calls for better hydrogeological monitoring and more localized studies to better understand the potential harms facing Brazil’s water sources.

Brazil plans new Amazon routes linking the Pacific & China’s New Silk Road
- New roads and riverways integrating the Brazilian Amazon and ports on the Pacific coast of South America are expected to be announced in 2025, reducing shipment costs to supply China.
- Brazil’s plans to build ports and roads to help move grains, beef and iron ore from the rainforest echo a development vision that dates back to the military dictatorship in the 1960s and 1970s.
- Environmentalists warn the new routes boost deforestation and encourage land-grabbers and ranchers to keep exploring the Amazon as a commodity hub.

Locals debunk myths linking endangered pink river dolphins to ‘love perfumes’
A colonial-era myth about endangered pink river dolphins in the Amazon has led to a false belief that perfumes or pusangas made from their body parts are potent love potions. According to a recent Mongabay documentary, the myth has created a market for the perfumes, further endangering the dolphins. The film, released in February, follows […]
Sumatran culinary heritage at risk as environment changes around Silk Road river
- Research shows that landscape changes across the Musi River Basin in Indonesia’s South Sumatra province risks food security across the river delta as fish stocks diminish and protein availability declines, including in the provincial capital, Palembang.
- Some fish traders and artisans in the city of 1.8 million worry culinary culture in Palembang is becoming endangered as rising sedimentation in the Musi River threatens the freshwater snakehead murrel fish.
- Reporting in March, during the fasting month of Ramadan, showed prices of food staples made from this fish increasing sharply from previous months as demand surged for fast-breaking events.

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.

Esmeraldas oil spill in Ecuador devastates rivers and wildlife refuge
A massive oil spill in Ecuador, in the northwestern Esmeraldas province, has covered multiple rivers and a key wildlife refuge in thick, black sludge, impacting more than half a million residents. A rupture appeared in a 500-kilometer (310-mile) pipeline operated by the state-owned oil company Petroecuador on Mar. 13, according to a statement by the […]
Indigenous Dayak community makes strides on Borneo toward forest autonomy
- In Mekar Raya, a semi-remote pocket of Ketapang district near the west coast of Indonesian Borneo, the local Dayak Simpan Indigenous society are navigating the complex bureaucracy of the state in a bid to gain semi-autonomous control of their customary forest.
- Under the national “social forestry” program, Indonesia’s central government has released more than 8 million hectares (20 million acres) from the national forest estate to management by local and Indigenous communities.
- The Dayak Simpan in Mekar Raya have previously resisted attempts by the palm oil industry to survey local land. Local sources say devolved management of the forest to the community will all but eliminate the risk of this land-use change.
- Several areas of the forestry are held sacred by the Dayak Simpan, with customary rules prohibiting the felling of trees or disturbance of water courses.

As the rainforest gets drier, Amazon Indigenous groups thirst for clean water
- The 2024 extreme and historical drought that hit the Amazon exposed a chronic problem: access to drinking water and sanitation in Indigenous lands, where only a third of households have proper water supply systems.
- In some Amazon rivers in Brazil, cases of diseases related to inadequate basic sanitation, such as malaria and acute diarrhea, have been increasing amid climate change and population growth.
- Indigenous organizations have been demanding the implementation of adapted infrastructures in the villages, such as water tanks, wells, cesspools and septic tanks.
- The Brazilian federal government already has resources and plans to begin addressing these issues.

River culture is the rhythmic pulse of the Bengal Delta (commentary)
- Reviving rivers in Bangladesh is not simply an ecological issue, but also a socio-cultural one, and an economic imperative.
- The government and the people must come together to protect and restore the rivers, not just for environmental sustainability and justice, but also to preserve the rich heritage and cultural identity associated with these waterways, a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Thai farmers demand action to restore ecosystems, compensate for invasive fish
- Citizens rallied in Bangkok this week demanding accountability and action from the government and private corporations following an outbreak of invasive fish that has ravaged Thailand’s freshwater ecosystems and aquaculture industry.
- Blackchin tilapia, an omnivorous species native to West Africa, is highly adaptable, breeds rapidly and is capable of outcompeting native wildlife and commercially farmed species, including shrimp.
- Thailand’s largest agricultural conglomerate has come under scrutiny because it obtained a permit to import the species in 2010, shortly before the first detections in the wild in the same province as its research facility.
- The activists urged the government to eradicate the species, compensate affected farmers and identity the parties responsible for the outbreak.

1 in 4 freshwater species worldwide at risk of extinction: Study

Still no sweet spot in 2024 for Nepal in balancing conservation & development
- Nepal faces ongoing challenges in balancing the development of infrastructure such as roads, railways and hydropower dams, with the need to conserve its rich biodiversity, forests and rivers.
- Infrastructure projects continue to raise ecological concerns, including habitat fragmentation, pollution, and risks to wildlife.
- Plans like the rerouting of the East-West Railway and buffer zones around rivers in Kathmandu have sparked protests due to fears of displacement, loss of property and economic hardships.
- These conflicts underline the challenges of aligning development with community and environmental needs.

River dredging in Bangladesh: Investigation shows government claims don’t add up
- A large part of Bangladesh, the country with the highest number of rivers, is a delta formed by sediments carried down by rivers from the Himalayan region. The population’s most significant livelihoods — agriculture, navigation and inland fisheries — depend on these waters.
- These rivers carry about 2.4 billion tons of sediment annually, including sand, clay and silt, a large portion of which needs to be cleared by dredging for navigability.
- As per a 2017 notice by Bangladesh’s water transport authority, the country restored around 547 kilometers (340 miles) of waterways between 2009 and 2017 to the county’s river system. The authority’s 2022-23 annual report says that between 2010 and 2023, the volume of 3,700 km (2,300 mi) of waterways increased.
- However, Mongabay found the authority’s claims of restoring waterways on this large scale is only on papers, as many of the rivers that are recorded as dredged are still not navigable.

Grassroots efforts sprout up to protect Central America’s Trifinio watershed
- A major watershed in Guatemala, Honduras and El Salvador has been so polluted, industrialized and interfered with that 20% of it could dry up in the next few decades, according to a U.N. report.
- The Trifinio Fraternidad Transboundary Biosphere Reserve, which covers the triborder region of Guatemala, Honduras and El Salvador, suffers from a free-for-all of deforestation, chemical runoff and mining that threatens the existence of the watershed.
- If it dries up, millions of people could be left without water for drinking, bathing and farming.
- While conservation groups continue to lobby for funding, residents frustrated with government inaction have started to organize themselves to fight everything from mining and runoff to illegal building development.

Greater Mekong serves up 234 new species in a year, from fanged hedgehog to diva viper
- Researchers and local nature enthusiasts described 234 new-to-science species across the Greater Mekong region in 2023.
- Among the new assortment of critters are sweet-smelling plants, glamorous snakes, a dragon lizard, a psychedelic-orange crocodile newt, and several new mammals, including a mole shrew and a fanged hedgehog.
- The Greater Mekong is a fast-developing region of Southeast Asia, characterized by intensive agriculture, internationally significant inland fisheries and rapid urban expansion.
- As such, the newly described species and their habitats are under pressure from multiple threats, not least from the illegal wildlife trade that also flourishes in the region. Experts say consistent and concerted action is required to secure their future.

Andes glacier melt threatens Amazon’s rivers & intensifies droughts
- A new study found that Andean tropical glaciers have reached their lowest levels in 11,700 years, with drastic consequences for the Amazon due to the overlap of the two ecosystems.
- The findings come to light as record droughts in the Amazon in 2023 and 2024, exacerbated by climate change, have severely impacted local communities, including food insecurity and lack of access to drinking water.
- The ice loss in the Andes could reduce the water flow to the Amazon rivers by up to 20%.
- Venezuela is on the verge of becoming the first country in modern history to lose all its glaciers.

Thai citizens protest plans for Mekong dam amid transboundary concerns
- Citizens in northern Thailand staged protests along the shore of the Mekong River on Dec. 7 to draw attention to a controversial dam slated to be built on the river’s mainstream over the border in Laos.
- They demanded Thai banks and policymakers withdraw their support for the scheme due to its as-yet-unknown cross-border environmental and social impacts.
- The protests follow a particularly turbulent wet season marked by record-breaking floods that wrought high costs on riverside communities. Experts have said the dam would exacerbate such events should it be built.
- Halting the project to allow sufficient time for thorough transboundary ecological and social studies is absolutely critical, the activists said.

The uncertain future of Amazon river dolphins amid historic drought
- This year, the drought in Amazon rivers is already worse than in 2023, when 209 pink and grey river dolphins were found dead in Lake Tefé, in Amazonas state, largely due to overheating of the waters.
- To avoid a new tragedy, local organizations have taken action in advance, establishing emergency operations with stronger monitoring, staff training and equipment acquisition.
- However, no dolphin deaths due to heat stress have been recorded this year; instead, dozens of carcasses of aquatic mammals have appeared in Amazon lakes as a result of another sinister effect of drought: increased interactions with humans.

Researchers find high levels of mercury in Amazon’s Madeira River water & fish
- In a groundbreaking expedition, researchers from Harvard and Amazonas State University began monitoring water quality and mercury contamination in the Amazon Basin’s largest tributary.
- The Madeira River Basin has been heavily impacted by human actions, such as hydropower plants, deforestation and illegal gold mining, which degrade its ecosystems.
- Initial results from Harvard reveal high levels of mercury in the Madeira, although still below the limit recommended by Brazil’s authorities.
- Predatory fish species showed mercury levels above the recommended limit, while scalefish traditionally consumed by riverine populations were below.

Rappahannock Tribe first in US to enshrine rights of nature into constitution
- The Rappahannock Tribe in Virginia has become the first tribal nation in the U.S. to adopt a tribal constitution that grants legal rights to a river, specifically protecting the Rappahannock River’s rights to exist, flourish, and maintain clean water.
- The constitutional provisions allow the tribe and individual tribal members to bring legal cases on behalf of the river itself, with a tribal court system planned for 2025 to enforce these rights.
- This historic move comes from a tribe that has lived alongside and been sustained by the river for thousands of years, with Chief Anne Richardson describing the river as “the Mother of our Nation,” which has provided physical, cultural and spiritual nourishment to the tribe.
- The Rappahannock’s actions are part of a rights-of-nature movement that includes Ecuador’s constitutional recognition of nature’s rights in 2008 and New Zealand’s granting of legal personhood to the Whanganui River in 2017.

Studies link stronger dengue outbreak in Bangladesh to climate change
- A typical consequence of climate change, drier monsoons with sudden bursts of heavy rain has led to days of inundation and long periods of standing water, creating an ideal situation for breeding mosquitoes, which may be linked to the stronger outbreak of dengue.
- Bangladesh has experienced noticeable changes in the timing and characteristics of its monsoon season. Traditionally occurring from June to August, the monsoon now extends from July to early October.
- Dengue cases have risen dramatically worldwide, with Asia responsible for 70% of reported instances, according to WHO. Researchers indicate that temperatures between 27 and 32 degrees Celsius are optimal for the breeding of Aedes mosquitoes, the vectors of the viral disease.
- As of Nov. 18, the death toll from the dengue outbreak in Bangladesh is 415, with around 80,000 infected, while the country recorded 1,705 dengue-related deaths in 2023.

Dam displaces farmers as drought parches Indonesia’s Flores Island
- In 2015, Indonesia announced the construction of seven dams to provide water in East Nusa Tenggara province, an eastern region of the archipelago where access to freshwater is scarce during the annual dry season.
- One of the national priority dams, the Lambo Dam on Flores Island, has yet to be finished because of a land dispute with Indigenous communities in Nagekeo district.
- Research shows that much of Indonesia, particularly in the east, face increasing water stress due to climate change, as well as drought spikes brought on by the positive Indian Ocean dipole and El Niño patterns.

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.

In Bhutan, a smoked fish tradition helps sustain a vanishing ethnic group
- Bhutan’s last remaining Olep hunter-gatherers rely on a traditional smoked fish, Nya Dosem, made from snowtrout (Schizothorax genus), to sustain their livelihoods.
- The community obtains special fishing permits to allow them to fish for these snowtrout, spending months along the Harachhu River and its tributaries in an area that is also home to the critically endangered white-bellied heron (Ardea Insignis).
- The Oleps’ fishing practices are monitored to ensure the local ecology is preserved, that spawning seasons are honored and that other local species are conserved; in this way, the environment sustains the Oleps, and the Oleps sustain the environment.

In Kenya, a river restoration initiative pays for itself, and then some
- The water supply for the Kenyan capital, Nairobi, depends on the Tana River, which flows for 1,000 km (620 mi) across the northern part of the country into the Indian Ocean.
- In recent decades, farmers have cut down forests to grow crops on ever-steeper hillsides in the river basin’s upper reaches, damaging water quality.
- The Upper Tana-Nairobi Water Fund was established in 2015, drawing money from corporations and government to pay for watershed restoration and reforestation of this vital resource.
- The fund has enjoyed some success, but obstacles include building up expert knowledge of nature-based solutions by officials in the water sector

Six months after its worst floods, Rio Grande do Sul works to bounce back
- A combination of wet El Niño weather and human-induced climate change were key drivers of the worst flooding event in Brazil’s Rio Grande do Sul state earlier this year.
- The flooding affected 90% of the state and displaced more than half a million people.
- Poor land management is also responsible for the region’s vulnerability to floods, as current agricultural practices in the highlands favor runoff and reduce the soil’s ability to soak up water, with lowlands particularly exposed to high waters.
- While some scientists are still deciphering the causes and behavior of the floodwaters, other experts are working to rehabilitate farmland, tackle soil erosion, and source native seeds for ecological restoration.

Mining and logging threaten Bolivia’s newest protected area
- The Gran Manupare reserve was created in January 2024 in northern Bolivia’s Pando department, making it the newest protected area in the country.
- However, the reserve already faces threats from gold mining along the Madre de Dios River, which forms its northern border.
- Logging is another threat that experts warn could enter Gran Manupare, which holds highly sought-after mahogany trees.

NGOs raise concerns over oil exploration in Republic of Congo national park
- NGOs are calling on the government of the Republic of Congo to revoke a permit allowing oil exploration in Conkouati-Douli National Park, the country’s most biodiverse area.
- They argue that oil exploration and exploitation will have a catastrophic impact on the park and local communities living in and around it.
- They also argue that the project runs counter to agreements reached with international donors to fund forest protection and breaks the Republic of Congo’s own environmental law.

Record-breaking floods in northern Thailand intensify scrutiny of Mekong dam project
- Major flooding along Mekong tributaries in northern Thailand has heightened scrutiny of plans to build a major hydropower dam spanning the pivotal watercourse over the border in Laos.
- Experts say the Pak Beng Dam would worsen severe seasonal flooding by elevating water levels upstream into the stretch of the Mekong that flows through northern Thailand.
- In 2023, Thailand’s national electricity authority signed an agreement to purchase electricity from the controversial scheme, essentially greenlighting the next phase of development.
- This week, farmers, activists and policymakers met in the flood-prone province of Chiang Rai to discuss the potential cross-border impacts of the dam, with many speakers urging the Thai government and Thailand-based investors to reconsider their support of the scheme due to the risks of the dam exacerbating devastating floods.

Supreme Court decision on saving Kathmandu rivers stirs up heated reactions
- The Supreme Court of Nepal has ruled to extend no-construction zones along major rivers in Kathmandu Valley, sparking varied reactions.
- Environmental activists praise the decision for addressing severe river pollution and encroachment, but the federal government has requested a review due to local opposition.
- The ruling introduces an additional 20-meter (66-foot) buffer zone, which would impact thousands of households, raising concerns about property rights and potential displacement.
- Critics argue the ruling will cause economic hardship and require substantial compensation, prompting the government and local authorities to seek revisions.

Extreme drought pushes Amazon’s main rivers to lowest-ever levels
- Amid an extreme, unprecedented drought, almost all major Amazon rivers have registered their lowest levels in history.
- Experts say the outlook for the next months is even worse, putting researchers on alert for the possibility of Amazon’s worst drought ever.
- The low river level in Manaus, Amazonas’ state capital, may increase prices of products shipped through the city’s harbor.
- The drought has isolated some Indigenous communities, while others have to walk long distances through dry riverbeds carrying groceries and equipment.

Lack of research as contaminated Yaqui River poses health risks
- Amid a water crisis, Yaqui communities in the northwestern Mexican state of Sonora lack safe drinking water due to contamination by arsenic, salinity and heavy metals as unveiled by several studies over the years.
- The water crisis, driven by decades of overexploitation, unequal water distribution and drought, intensifies contamination, particularly affecting coastal areas with saltwater intrusion and surpassing safe limits in certain regions.
- Members of the Yaqui tribe blame mining operations and agribusiness for the contamination, but there are few studies to confirm their source.
- They argue contamination has led to diabetes and health complications among community members, as well as cultural impacts.

Scientists find unexpected biodiversity in an African river, thanks to eDNA
- Scientists have used environmental DNA analysis to identify 125 species of aquatic and terrestrial animals in the remote Corubal River in West Africa.
- The identified species include critically endangered animals as well as species that weren’t previously known to occur in the region.
- The Corubal flows through Guinea and Guinea-Bissau; because of its remote nature, there haven’t been a lot of large-scale attempts to study the biodiversity in the river and its basin.
- The scientists are also working to collect specimens and tissue samples from animals encountered along the river to build a DNA reference database for the future.

In the Brazilian Amazon, seedlings offer hope for drying rivers
- In Brazil’s Maranhão state, the advance of monoculture and decades of forest destruction have driven a shift in precipitation patterns, diminishing rains and drying out springs that feed important rivers.
- This represents a major threat for the Guajajara Indigenous people, for whom these springs hold spiritual significance and guarantee the health of the rivers they depend on for fishing, bathing, drinking and cultural rituals.
- In an effort to restore drying springs, Indigenous people in the Rio Pindaré reserve are mapping headwaters and planting species native to the Amazon rainforest – like buriti, pupunha and açaí palms – along their margins.
- Scientists say this type of reforestation could help restore balance to water cycles in the region, mitigating the broader impacts of drought and climate change.

Rio Tinto-linked mine still not fulfilling promises to Mongolian herders
- In 2017, nomadic herders in Mongolia’s Gobi Desert secured an agreement obliging one of the world’s largest copper-gold mines, Oyu Tolgoi, to make good on a list of 60 commitments, including compensation and improved access to land and water.
- Today, compliance researchers and herders say two-thirds of these commitments are complete and or in progress, but complain of slow progress with the remainder, including the all-important issue of access to clean water.
- Communities have also expressed concern over seepage of mining waste into the groundwater, and say the company, a subsidiary of multinational mining giant Rio Tinto, should be held accountable.
- The nomadic herding way of life is on the decline the area due to lack of progress on achieving these other commitments, herders tell Mongabay.

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.

A national park and its rangers in Bolivia endure persisting road construction, illegal mining
- Illegal mining continues in the headwaters of the Tuichi River in northwestern Bolivia, with miners encroaching into the strictly protected areas of the Madidi National Park.
- As part of a project backed by La Paz’s government, a road is being built through the middle of the protected area,.
- Madidi’s park rangers are living under constant strain. They are threatened and attacked by miners, and are unable to enter some parts of the protected area to carry out their duties.

The Andes are a key supplier of gold for the Amazon Basin
- In recent decades, gold mining in Peru is no longer only taking place in the Andean areas but also in the Amazon. There, illegal miners are increasingly exploiting the precious metal found in alluvial deposits.
- A similar situation can be observed in the Bolivian Yungas, very close to the Peruvian border in the Madre de Dios region. Despite operations against illegal mining, the activity persists.
- On the border of Ecuador and Peru, much of the area comprising the mineral-rich Cordillera del Condor has been set aside as a protected area or Indigenous territory, but there are still large areas open to mining, particularly in Ecuador where multinational corporate miners are investing in both copper and gold mines.

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.

Reporting confirms alleged Indigenous rights violations in Nepal hydropower project
- Tucked between mountains sacred to Indigenous peoples in eastern Nepal, a conflict is brewing between Sangrila Urja Pvt. Ltd., a hydropower company, and yak herders who say the company violated the law by lying in government reports.
- The tug-of-war between the hydropower company and the Bhote Singsa communities is taking place in the Lungbasamba landscape, a biocultural heritage home to endangered flora and fauna and that communities have preserved for generations.
- Mongabay was able to verify most of the communities’ claims and confirm fabricated information in the environmental impact assessment, forged signatures during a public hearing and a lack of proper consultation with the community. The company director refutes the allegations and evidence and says it awaits the resumption of its activities once a lawsuit filed by civil society organizations confirms they can move forward with the project.
- This report won first place from the 2025 Indigenous Media Awards for Best International Indigenous Coverage.

Holistic care for an Ethiopian lake system: Interview with Redwan Mohammed
- Redwan Mohammed leads a project to restore Ethiopia’s Ziway-Shalla river basin, which is under pressure due to deforestation and erosion.
- Abijata-Shalla Lakes National Park lies at the basin’s heart, centered on a pair of saline lakes that provide vital habitat to migratory waterbirds.
- The river basin is also home to around 60,000 farmers and herders as well as commercial flower farms and other light industry.
- Mohammed’s employer, Wetlands International, focuses on protecting wetlands because they provide essential ecosystem services such as water filtration, flood control, and habitat for wildlife.

Small steps towards larger goal of protecting East African wetlands
- Conservation NGO Wetlands International had lofty ambitions when it rolled out its Source to Sea project in East Africa in 2021, covering the Rift Valley wetlands and the Indian Ocean mangroves.
- Difficulties that arose included underestimating the time needed to get government agencies, civil society and community groups on board, overambitious planning, and communication barriers with locals.
- They quickly realized that residents’ urgent livelihood needs needed to be acknowledged and addressed before more abstract concepts such as wetland conservation and integrated catchment management could be introduced.
- Today, the project has made essential contributions to the lives of participating communities and the catchment’s health, created awareness of mangroves and wetlands among the different groups involved, and helped influence policies on water resource management.

In the wake of Bangladesh’s deadliest dengue outbreak, researchers respond
- In 2023, Bangladesh experienced the deadliest outbreak of dengue fever in the country’s history.
- Climate change will likely make severe disease outbreaks more common.
- Common prevention strategies, like insecticides, are becoming less effective as mosquitoes gain resistance and the nature of disease changes.
- In response, researchers, nonprofits and Bangladeshi residents are searching for ways to protect their communities and families.

A tribe once declared ‘extinct’ helps reintroduce salmon to the Columbia River
- For thousands of years, Kettle Falls was a vital salmon fishing ground for the Sinixt, but early 20th-century dam construction blocked salmon migration.
- Wrongfully declared extinct in Canada in 1956, the Sinixt fought for recognition and were officially acknowledged as Aboriginal Peoples of Canada in 2021.
- In 2023, the U.S. government signed a $200 million agreement with a coalition of tribes, including the Sinixt, to fund an Indigenous-led salmon reintroduction program into the Columbia River system above dams in Washington.
- Sinixt leaders say this project is an important effort to help right a historical wrong in the legacy that led to their “extinction” status, while many hope to one day join salmon efforts on their traditional territory in Canada.

Indigenous communities in the Bolivian Amazon combat droughts and floods
- The Tsimané, Mosetén and Tacana Indigenous ethnic groups in the Bolivian Amazon feared the worst for early 2024. They believed that the cycle of floods would bring misfortune and affect their communities
- However, the water management projects they have implemented have provided favorable results and helped the communities avoid disasters. This is an example of a communitywide effort to commemorate World Water Day 2024, which was March 22.
- Members of these Indigenous communities collect water from several watersheds and transport it through kilometers of pipes so that it reaches their homes, a complex engineering project that also has allowed them to adapt to the more intense droughts and floods caused by climate change.

On heavily dammed Mekong, tracking study tries to find where the fish are going
- Despite the huge environmental and economic importance of migratory fish in the Mekong River, there’s been little empirical data documenting where and how fish travel within the Lower Mekong Basin.
- For a recent study, researchers teamed up with fishers in Laos to tag hundreds of fish with transponders before releasing them to continue their migrations.
- The study found that these fish travel hundreds of miles along the river, including through several active and planned hydropower projects in Laos.
- It also found that at least a portion of the fish were able to traverse a fish ladder on an existing dam.

Loss of water means loss of culture for Mexico’s Indigenous Yaqui
- The sacred waters of the Yaqui tribe in the northwestern Mexican state of Sonora have dried up after decades of overexploitation, unequal water distribution and drought.
- This poses serious threats to Yaqui culture, which previously used certain sections of the Yaqui River for traditional ceremonies.
- It has also led to the decline of plant and tree species, such as the alamo (Ficus cotinifolia) and the giant reed (Arundo donax), which are used to build traditional structures in Yaqui villages.
- Important features of the Yaqui ritual dance, known as the pascola and deer, rely on the cocoons of the four-mirror butterfly, an endemic species that depends on the Yaqui River for its survival and is in decline.

Study to benchmark water quality finds key Amazon tributary in good shape
- Researchers have found that water quality in Brazil’s Negro River, the second-largest tributary of the Amazon, remains largely excellent, the result of a sparse human presence and strong conservation measures.
- The sampling of 50 sites along the main stream of the blackwater river was carried out to develop a water quality index (WQI) for this type of Amazonian river, which hasn’t been done before.
- In August, the research group will present this new WQI to the Amazonas state water resources council; if approved, the index will be used as the model for monitoring blackwater rivers in the state.
- The project on the Negro is the first of the program, which aims to develop a WQI for each of the largest rivers in Amazonas state, such as the Madeira, Solimões and Purus, and establish continuous monitoring during the wet and dry seasons.

Cambodia’s Funan Techo Canal project: A catalog of worries (analysis)
- Cambodia plans to build a 180-km (110-mi) canal from its capital to its coast on the Gulf of Thailand, a $1.7 billion project aimed at reducing its dependence on moving cargo through ports in neighboring Vietnam.
- But this analysis concludes that the plan is financially unfeasible, would have severe environmental impacts, and would exacerbate water scarcity in a region already suffering from critically low levels in the Mekong.
- The Cambodian government’s argument that the canal would make freight transport cheaper falls apart under cursory calculations, which show shipping costs will be even higher than via the Vietnamese ports.
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

Indigenous communities in Sarawak left in the dark about hydropower proposal
- Malaysian officials recently announced new dam projects on three rivers in the Bornean state of Sarawak without the free, prior, and informed consent (FPIC) of local people.
- The managing director of the Sarawak-based NGO SAVE Rivers, Celine Lim, says her community relies on the Tutoh River for food and for transport, so the announcement “definitely threw the community into a frenzy because no one knew of this plan before the announcement.”
- Project opponents have gathered 650 signatures on a petition calling for more information from the government before the project can move forward, after initial requests for information were ignored.
- Lim joins Mongabay’s podcast to share with co-host Rachel Donald how the potential dam projects could impact the rivers and human communities, and reflects on lessons learned from a recent visit with Indigenous communities in California who successfully argued for the removal of dams on the Klamath River and are now restoring its floodplain.

As drought parches Mexico, a Yaqui water defender fights for a sacred river
- In the northwestern Mexican state of Sonora, Mario Luna Romero faces constant threats to his life for fighting to protect his community’s rights to its water in the region.
- Within the Yaqui Territory are the remnants of the Yaqui River, which is sacred to the Indigenous tribe and has been drained of all its water after decades of overexploitation, unequal water distribution and droughts. Mexico, including the Yaqui Valley, is experiencing a deadly heat wave, drought and water shortages.
- Luna was arrested in 2014 and spent a year and 11 days in a maximum-security prison; meanwhile, other colleagues have been harassed by government officials or killed by criminals.
- This 4-part series won for Best Coverage of Indigenous Communities as part of the 2025 Indigenous Media Awards.

Global migratory freshwater fish populations plummet by 81%: Report
- A new global study reveals an average 81% decline in migratory freshwater fish populations between 1970 and 2020.
- Habitat loss, degradation and overfishing are the main threats to migratory fish, which are crucial for food security, livelihoods and ecosystems worldwide.
- While 65% of species have declined, 31% have shown increases, suggesting that conservation efforts and management strategies can have positive impacts.
- The report calls for stronger monitoring efforts, protection of free-flowing rivers, and meeting global biodiversity goals to address this crisis.

From the Amazon to the Himalayas, an invasive catfish makes its Nepal debut
- Researchers discovered specimens of Pterygoplichthys disjunctivus, an Amazonian catfish, in a river in eastern Nepal, marking the first record of this species in the country’s rivers.
- How the fish ended up here remains uncertain, with possible explanations including religious release or upstream migration from India.
- Experts warn the presence of the species could severely disrupt Nepal’s freshwater ecosystems, due to the lack of natural predators and their potential to outcompete native species.

If forests truly drive wind and water cycles, what does it mean for the climate?
- Theoretical physicists Anastassia Makarieva and Viktor Gorshkov developed the controversial “biotic pump” theory more than a decade ago, which challenges traditional climate and hydrological science.
- The theory posits that forests drive moisture-laden air currents, thereby governing wind and rain and implying that further global forest loss could have unknown effects on weather and water supplies.
- While yet to be disproven or validated, some scientists say it’s vitally important to study and test this theory, and potentially include it in climate-modeling scenarios.
- Makarieva joins Mongabay’s podcast to discuss the theory and its implications for future climate modeling with co-host Rachel Donald.

In Indonesia’s Aceh, a once-isolated forest hosts local travelers on bamboo rafts
- In the semiautonomous region of Aceh, an Indigenous community has repurposed the bamboo rafts they use to commute downriver to sell tourism services to nearby urban settlements.
- The forests of Samar Kilang were once out of reach of Indonesia’s economy, until road access enabled local people to travel into the highlands.
- The nonprofit Katahati Institute has been working with women in Samar Kilang to market nontimber forest products and support the community’s ecotourism venture.

From Egypt to Syria, ‘water cancer’ chokes waterways
- Water hyacinth, an invasive species from the Amazon, is a major threat to freshwater life and livelihoods in Syria’s Orontes River and in Egypt’s Nile Delta.
- The plant grows and spreads quickly, outcompeting other species for space, oxygen, nutrients and sunlight.
- Along the Orontes, in a region controlled by opposition groups, farmers and fishers have little recourse for tackling the invasive species.
- In the Nile Delta, communities have more experience battling the plant and state-led dredging campaigns help clear water hyacinths every year, but they remain hard to control.

On World Otter Day, an uphill struggle for these creatures in Nepal
- Severe degradation of Nepal’s rivers due to overexploitation has negatively impacted otters and other aquatic species.
- Dumping of raw sewage and industrial waste, leaching of agricultural pesticides, and rapid urbanization and infrastructure developments are undermining otter habitats across the country.
- The widespread damming of rivers coupled with unsustainable fishing practices have also reduced food sources for Nepal’s otters.
- The country is home to two, possibly three, otter species, but conservationists say funding and attention for the welfare of these animals tend to be overshadowed by that for Nepal’s higher-profile wildlife, such as tigers and rhinos.

Will the Mekong and Salween pay the price of China’s energy transition?
- Proposals by some of the world’s largest greenhouse gas emitters to transition their energy sectors away from fossil fuels and toward renewables have generally been welcomed by the scientific community as progress in the right direction.
- However, while acknowledging the energy transition as essential, energy experts caution policymakers to also consider the unintended social and ecological consequences of scaling up renewable infrastructure, such as large-scale hydropower dams and wind and solar farms.
- A new study finds that China’s plans to decarbonize its energy sector by 2060 could have inadvertent but severe impacts on local farmland and transboundary river basins, including the regionally significant Mekong and Salween.
- The authors say that strategies to reduce electricity demand combined with increased investment in emerging energy technologies could curb the need for further hydropower expansion in the upper stretches of the pivotal rivers, thereby reducing cascading downstream impacts.

Banks backing Mekong hydropower failing on due diligence, report reveals
- A new report shows that major banks operating in Southeast Asia are failing to address the environmental and human rights consequences of their investments in large-scale hydropower dams along the Mekong River.
- The report from sustainable finance watchdogs reveals regulatory shortcomings at regional and national levels that it says fail to hold banks accountable for their investments.
- Riverside communities and rights groups have long questioned why banks operating in Mekong countries continue to fund environmentally damaging hydropower projects in neighboring countries, despite the high costs and consequences for communities in their own country.
- The report calls on financial institutions to adopt more sustainable banking policies and practices when deciding which projects to support.

Indigenous communities along Argentina’s Río Chubut mobilize to conserve waterway
- A caravan of Indigenous Mapuche activists recently concluded an 847-km (526-mi) trek down Argentina’s Chubut River, meeting with communities along the way to raise awareness of the issues they face along the shared waterway.
- From each trawün, or gathering, they determined that Indigenous access to land and water is diminishing, that large-scale projects on their lands are going ahead without their prior informed consent, and that Mapuche communities need a unified stance toward state decisions.
- Huge swaths of land along the river have been bought up by private interests, including foreign millionaires, cutting off access for the Mapuche to the Chubut that they consider not just a physical resource but a spiritual entity.
- The Mapuche are also concerned about policy changes under Argentina’s new libertarian administration, which has already kicked off a massive deregulation spree and could lift a ban on open-pit mining in the region.

Meet the 2024 Goldman Environmental Prize Winners
- This year marks the 35th anniversary of the prestigious Goldman Environmental Prize, which honors one grassroots activist from each of the six inhabited continents.
- The 2024 prize winners are Alok Shukla from India, Andrea Vidaurre from the U.S., Marcel Gomes from Brazil, Murrawah Maroochy Johnson from Australia, Teresa Vicente from Spain, and Nonhle Mbuthuma and Sinegugu Zukulu from South Africa.

Latest Peruvian oil spill cuts Indigenous communities from life-giving river
- On March 5, a collision between two oil barges in the Peruvian Amazon led to an oil spill in the Puinahua River, near Pacaya-Samiria National Reserve, a protected region of rainforest.
- Since the spill, local Indigenous communities, who almost exclusively depend on the river for their livelihoods, have been unable to collect water or fish due to fear of contamination.
- The impacted communities are awaiting compensation for their losses, yet face a deadlock as environmental assessments, which could take weeks, must be conducted first before payments are made.
- The ecological, economic and social impacts of the oil spill have not yet been published; for decades, the Peruvian Amazon has been subjected to hundreds of oil spills and leaks, which experts say have wreaked havoc on the basin.

Bangladesh uses satellite transmitters on saltwater crocodiles in Asia’s first
- On March 13, the Bangladesh forest department tagged satellite transmitters on two saltwater crocodiles for the first time in Asia and released them in the Sundarbans waters.
- So far, four saltwater crocodiles — three from captivity and one from the wild — have been tagged and the preparation is in place to tag more.
- The forest department has already started collecting data using the satellite transmitters to understand the crocodile’s habits in this ecosystem and identify nesting its hotspots, ecology, mortality rate and habitat range.
- Experts say the satellite data will play an important role in crocodile conservation in Bangladesh, where the species is critically endangered, and will help the authorities make proper conservation management plans to protect it.

Indigenous efforts to save Peru’s Marañon River could spell trouble for big oil
- In March, the Federation of Kukama Indigenous Women in the Parinari district of Loreto won a lawsuit against the oil company Petroperú and the Peruvian government, protecting the Marañon River from oil pollution.
- Since the 1970s, the exploration of oil reserves in the Peruvian Amazon has resulted in hundreds of oil leaks and spills, compromising the health of Indigenous communities.
- While the defendants have already appealed the decision, a favorable ruling in higher courts could force oil and gas companies to answer for decades of pollution in the Peruvian Amazon.

Sumatra villages count cost of deadly river tsunami swelled by illegal logging
- Several days of extreme rainfall beginning March 7 triggered fatal flash flooding across Indonesia’s West Sumatra province, resulting in at least 30 deaths and devastating villages on the fringe of Kerinci Seblat National Park.
- Deforestation upstream of the affected areas has exacerbated the risk of landslides and flash floods, according to officials.
- The Indonesian Forum for the Environment, a national civil society organization, called for government action to address illegal logging and land management practices to prevent future disasters.

Amazon prosecutors get sharper impact tool to charge illegal gold dealers
- New research from the NGO Conservation Strategy fund, working with federal prosecutors in Brazil, has refined a tool that puts a dollar value on the socioenvironmental costs of illegal gold mining across vital ecosystems in the Amazon.
- Brazilian environmental investigators and prosecutors say the updated Mining Impacts Calculator is improving cases they’re bringing against the largest buyers of illegal gold in the country.
- Each kilogram of gold of artisanal mining causes damage valued at up to $389,200, more than twice the market value of gold, the new study found.
- Prosecutors in Colombia, Peru, Ecuador and other Amazonian countries are also adopting the new calculator, but with gold values soaring and official corruption entrenched, observers say that reducing illegal mining will remain a significant challenge.

‘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.

Nepal’s release of endangered crocs into historical habitat raises concerns
- Nepal recently released 25 critically endangered gharials into a tributary of the Mahakali River to reintroduce them to historical habitats, but concerns have arisen over transparency and timing of the process.
- Gharials are released into the Chaudhar river, part of the Terai Arc Landscape, to augment dwindling populations, although previous translocations have yielded mixed results.
- Researchers highlight challenges faced by gharials, including migration obstacles due to dams and barrages, and they advocate for better timing of releases to optimize adaptation and survival.
- Issues such as lack of publicized government studies, potential influence of reciprocal gifts in translocation decisions and denial of budget-related motives are raised amid efforts to conserve gharials.

Projected Pantanal waterway threatens protected areas, may render navigation impossible
- Construction of a waterway on the Paraguay River could accelerate a dehydration process already underway in Brazil’s Pantanal, impacting priority conservation areas and quality of life in local communities.
- Licenses for new fluvial ports are already being issued along the river and a contract signed by the administration of President Luiz Inácio Lula da Silva makes way for dredging needed for barges loaded with ore and grains to pass.
- The Association for Tropical Biology and Conservation has published a resolution asking that the project not move forward because of the risks it poses to the Pantanal biome.

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.

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.

Nile Basin farmers grow food forests to restore wetlands and bring back a turtle
- Sugarcane is a widely grown crop in the Nile Basin, but its destructive effects on soils, water resources and biodiversity have become increasingly apparent.
- As the thirsty crop draws down water resources, aquatic species like the critically endangered Nubian flapshell turtle suffer a loss of habitat, forage and nesting sites.
- In an effort to revive soils, diversify diets and incomes, and boost water levels that many animals rely on, communities are implementing agroforestry projects in lieu of monocultures.
- The resulting “food forests” attract an array of wildlife while refilling wetlands and river systems where the culturally important flapshell turtles swim.

Gharial conservation plan leaves Nepal fishing communities searching for new jobs
- Since the creation of Chitwan National Park, some Indigenous Bote people who have lost access to their ancestral lands and livelihoods have been employed by the park as gharial keepers to help conserve the critically endangered species.
- However, community members say the park’s restrictions on their fishing livelihoods to protect the reptile species is taking a toll on their economic needs and restricting their rights; the possibility of working as gharial keepers and other livelihood alternatives are insufficient, they say.
- Many parents are now encouraging their children to migrate to Persian Gulf countries to work as migrant laborers in order to lead a better material life.
- Conservationists say restricting fishing is an important step in protecting the species, which would struggle to survive if many economically dependent communities fished in the rivers.

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.

Controversy brews over proposed dam on Kathmandu’s Bagmati River
- A proposed dam on Kathmandu’s Bagmati River aims to collect rainwater during the wet season and release it in the dry season to rejuvenate the river, but skeptics question its viability and safety.
- Concerns include environmental impact, potential destruction of trees, pollution and the risk of dam failure in earthquake-prone Nepal.
- Political, ecological and community-related questions remain unanswered, with some advocating for alternatives and further analysis before proceeding.

Hydropower in doubt as climate impacts Mekong Basin water availability
- Warmer and drier wet seasons in the upper basin of the Mekong River are affecting the availability of water for hydropower generation along the major watercourse, according to a new analysis.
- At a recent online discussion, regional experts questioned the viability of hydropower on the Mekong as a long-term, sustainable energy solution, given the increasing presence of climate risks.
- With large-scale dams in upper parts of the basin failing to fill their reservoirs, panelists at the event asked whether they are truly worth their documented impacts on downstream ecosystems, livelihoods and communities.
- Panelists recommended continued information sharing and improved coordination of dam operations to preserve the river’s crucial flood pulse that triggers the seasonal expansion of Tonle Sap Lake in Cambodia, and also highlighted the conservation importance of the Tonle Sap watershed, including tributaries in Cambodia’s Cardamom Mountains.

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.

Risks to Myanmar’s last saltwater crocs point to coastal conservation needs
- A new study confirms that Myanmar’s last population of saltwater crocodiles is perilously isolated and that without efforts to connect suitable coastal wetlands, the future of the species is in the country is uncertain.
- Deforestation and conversion of coastal habitats for commercial production, persecution due to conflicts with people, and hunting and wild capture to supply demand for crocodile meat and skin products have all taken their toll on crocodile numbers.
- The researchers recommend conservationists and policymakers in Myanmar focus on reconnecting remaining coastal habitats, including existing coastal protected areas, and identify key crocodile habitat areas and potential movement corridors to aid such conservation action.
- Enhancing coastal habitat connectivity would not only enable crocodile population recovery, it would also reduce pressure on communities coping with negative interactions with crocodiles.

Amazon catfish must be protected by the Convention on Migratory Species COP-14 (commentary)
- The latest Convention on Migratory Species of Wild Animals (also known as the Bonn Convention) meeting (COP-14) is taking place in Uzbekistan this month, and the government of Brazil has proposed protections for two catfish species with extraordinary migrations, the dorado and piramutaba (manitoa).
- The dorado’s migratory journey for instance spans a distance of 11,000+ kilometers round trip, from the Andes to the mouth of the Amazon River, and along the way it connects multiple ecosystems and feeds local and Indigenous fishing communities, but is under increasing threat.
- “During COP-14, the dorado and piramutaba will take a prominent place thanks to the Brazilian Government’s proposal to include them in CMS Appendix II…It is essential that the governments at the meeting adopt Brazil’s proposal,” a new op-ed argues.

New guidebook supports U.S. tribal nations in adopting rights-of-nature laws
- A new guidebook aims to assist tribal nations across the United States in adopting legal frameworks that recognize the rights of nature.
- The growing rights-of-nature movement seeks to protect the environment by legally acknowledging its inherent right to exist and thrive independent of human use.
- The guide examines real-world challenges and pathways for passing laws and includes case studies of tribes that have enacted rights-of-nature laws through constitutions, ordinances and resolutions.
- The guide contains practical guidance on steps like surveying community perspectives, holding educational gatherings, and forming planning committees.

Communities on troubled Java river mold future from plastic waste
- The Ciliwung is a highly polluted river running from Mount Pangrango in western Java, through the city of Bogor, before ending in the bay north of Jakarta, Indonesia’s capital.
- Since 2018, Bogor Mayor Bima Arya Sugiarto has overseen an initiative to rehabilitate the river, which was awash with plastics and dangerous levels of fecal coliform bacteria.
- Bogor is among more than 50 global cities participating in the Plastic Smart Cities, initiated by WWF to help eliminate plastics from nature.

Nepal’s gharial population rises, but threats to the crocs persist
- The population of critically endangered gharials in Chitwan National Park, Nepal’s stronghold for these crocodiles, increased by around 11% as of the start of 2024, totaling 265 individuals compared to 239 the previous year.
- While the increase is positive, a recently published study shows the critically endangered crocs are unevenly distributed throughout their range, with threats from fishing, changes in river flow, and infrastructure development deterring them from certain prime habitats.
- The study also flagged the low success rate of a raise-and-release program for captive-bred gharials: 404 gharials have been released under the program, but the overall population has increased by just 80.
- Juveniles released under the captive-breeding program are likely suffering high mortality rates in the wild or getting washed downstream to India; experts say a possible solution is to release them as far upstream as possible.

Courage & calm despite attacks: Q&A with Colombian activist Yuly Velásquez
- For years, Colombia’s largest oil refinery, owned by the national oil company Ecopetrol, has discharged oil and toxic waste into water bodies, impacting fish and the livelihoods of fishers.
- Yuly Velásquez, a local fisher and president of an environmental organization, has spent years documenting water contamination and corruption linked to the refinery, and she faces consistent threats and attacks.
- According to a 2022 report by the NGO Global Witness, Colombia is the most dangerous country in the world for environmental and land defenders, with 60 murders that year.
- In this interview with Mongabay, she discusses the threats environmental defenders face in Colombia and what helps her stay resilient in the face of attacks.

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

Why the Amazon’s small streams have a major impact on its grand rivers
- An unprecedented time-series study in the basin of the Tapajós River, a major tributary of the Amazon, assesses the level of degradation of small rivers threatened by agribusiness expansion.
- Researchers from several universities will assess the conservation status of 100 streams spread between the municipalities of Santarém and Paragominas, at the confluence of the Tapajós and the Amazon, which were first analyzed in 2010.
- The impact of dirt roads and their network of river crossings, which causes sediment load, siltation, erosion and changes in water quality, was one of the factors that caught researchers’ attention in the initial time-series study.
- Experts say that local development models should ideally start from water to land, rather than the other way around, given the importance of water for the rainforest, its biodiversity, and the inhabitants who depend on both.

The waters of the Xingu: A source of life at risk of death
- In Xingu Indigenous Park in the Brazilian Amazon, rivers and lakes are natural arteries that provide life for animals and Indigenous communities, serving as a base for eating, bathing, social interaction and refuge in times of drought.
- The waters of the Xingu, however, are threatened by monocrop plantations around the park, which dry up the springs and pollute the rivers with pesticides.
- At the same time, climate change is exacerbating the periods of drought, with some rivers drying up entirely during these times.
- In this photo essay, photographer Ricardo Teles shows the relationship that the Indigenous peoples of the Xingu have with the waters that bathe their territory.

Illegal gold mining threatens Indus River water and biodiversity in Pakistan (commentary)
- The Indus River in Pakistan is being extensively disturbed by unregulated mining of the river’s bed (‘placer mining’) for gold.
- Numerous operations employing an estimated 1,200 heavy machines dig daily into the riverbed and dump buckets of sediment and rocks into screening devices, destroying habitat and muddying the water flowing downstream.
- “It is crucial to the development for the region’s economy and environmental preservation efforts to regulate placer gold blocks along the Indus River,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Xingu waters: source of life at risk in the Brazilian Amazon
XINGU INDIGENOUS PARK, Brazil — Xingu Indigenous Park, located in the southern Brazilian Amazon, spans 26,400 square kilometers and is home to 16 Indigenous groups. These communities rely on the park’s rivers and lakes for food, social interaction, bathing, and as a refuge during droughts. However, the Xingu water basin faces significant threats from monoculture […]
Conservation ‘setback’ looms as Nepal opens protected areas to hydropower projects
- Nepal’s government has approved a controversial new proposal allowing the development of large-scale hydropower plants within protected areas, prompting concerns about conservation setbacks.
- The “Construction of Physical Infrastructure Inside Protected Areas” procedures was officially approved Jan. 4, permitting hydropower developers to build projects entirely within protected areas, release minimal water during the dry season, and acquire land more easily.
- Conservationists, lawyers and Indigenous communities have opposed the policy, calling it legally flawed and warning that it threatens conservation achievements in the face of climate change.
- More than two dozen conservationists submitted feedback during the policy’s public consultation phase, but these weren’t accommodated to any significant degree in the final document.

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

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

Illegal gold mining devastates Peruvian Amazon river and communities
- Mongabay Latam traveled along 38 kilometers (24 miles) of Peru’s Cenepa River, near the border with Ecuador, where illegal mining dredges run around the clock in search of gold, hemming in seven Indigenous Awajún communities.
- The constant mining activity and presence of the miners has brought violence, crime and sexual exploitation to the Awajún communities and wrought widespread environmental destruction that shows no signs of slowing.
- Police and environmental defense leaders conducted raids in early October, but the lack of permanent enforcement in this part of the Amazon has allowed the dredging rafts to returned and once again churn up the river basin.

Study: Fishing with pesticides and dynamite puts Ecuadorian Amazon in peril
- Illegal fishing with agrochemicals and explosives across several of Ecuador’s Amazonian states is an uncontrolled problem, causing long-lasting, irreversible damage to aquatic ecosystems, recent research has shown.
- The study links high levels of poverty to the wider practice of unsustainable fishing, and calls for tighter controls on the sale and availability of agrochemicals and dynamite across the country.
- Fish caught using toxic chemicals can be dangerous for human consumption, the study warns, and says there should be more action to help educate communities about these dangers.

Could mugger crocodiles be brought back from regional extinction in Bangladesh?
- Once, mugger crocodiles (Crocodylus palustris) were common in Bangladesh’s major rivers, including the Padma, Jamuna, Meghna and most of their tributaries, but the species is thought to have gone extinct in the country due to unchecked poaching for its prized skin.
- Although the IUCN in 2000 declared the mugger regionally extinct in Bangladesh, three adult muggers were recovered from the country’s river and water bodies in only 11 days, Oct. 17-28 this year.
- The crocodiles were taken to the Karamjol Crocodile Breeding Centre in Khulna, and authorities are working on how muggers could be brought back to nature by increasing their population through captive breeding.
- Experts suggest establishing a safe zone for the crocodiles in the upper Padma River.

Cocopah Tribe aims to restore Colorado River habitat — and tribal culture
- On the lands of the Cocopah Tribe in the U.S. state of Arizona, declining water levels on the Colorado River have paved the way for invasive plants to take over a riverside once full of native trees.
- Native vegetation along the river not only provides habitat for wildlife but also has shaped Cocopah culture by providing resources to build homes, art and other items.
- This year, the Cocopah Tribe’s Environment Protection Office cut the ribbon on a project to restore land along the river to what it looked like decades ago, complete with a walking trail.
- For 2024, the tribe plans to use $5.5 million in grant funding to restore habitat and plant native trees along an even longer stretch of the river, helping to preserve Cocopah culture for generations to come.

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.

Paradise lost? Brazil’s biggest bauxite mining firm denies riverine rights
- Mineração Rio do Norte (MRN), Brazil’s largest bauxite producer, launched a new mining project in the Amazon region in 2019 but failed to notify and consult four impacted traditional riverine communities that have been established for generations. The villages say their lives are heavily impacted.
- MRN’s stance of no significant impact is backed by IBAMA, Brazil’s environmental agency, because it only is required to recognize Indigenous and Quilombola populations as legitimate traditional peoples guaranteed prior, free, informed consultation — a right enshrined in international law.
- Other traditional riverine communities are being denied such a right, say critics who are calling on President Luiz Inácio Lula da Silva’s government to instruct IBAMA to reduce the impact of mining on riverine communities.
- Action by IBAMA could help preserve the way of life for hundreds of traditional riverine people likely to be affected by a series of new mines planned by MRN. The ruling could also act as a precedent for other traditional communities not currently guaranteed prior, free, informed consultation.

Brazil’s biggest bauxite mining firm denies riverine rights
ORIXIMINÁ, Pará state, Brazil — In 2019, Mineração Rio do Norte (MRN), Brazil’s largest bauxite producer, initiated a controversial new mining project in the Amazon region without notifying or consulting four traditional riverine communities that have thrived there for generations. These villages report significant disruptions to their way of life due to the mining activities. […]
How scientists and a community are bringing a Bornean river corridor back to life
- Decades of deforestation to make way for oil palm monoculture have transformed the Kinabatangan River floodplain in east Sabah, Malaysian Borneo, dividing wildlife populations and confining many of the region’s most iconic species to small fragments of forest that cling on along the river.
- Local communities and conservation initiatives are working together to restore and reconnect pockets of remaining habitat along the river to preserve the vital wildlife corridor, but restoration in the unpredictable and often-waterlogged floodplain is notoriously difficult.
- One such initiative, Regrow Borneo, is facing the challenge by leveraging the expertise of scientists and local knowledge of community members who have been planting forests along the Kinabatangan for decades.
- They say that by focusing their approach on a model that benefits both people and wildlife, they hope their program inspires others to shift away from simply planting numbers of trees toward restoring forests where they’re most needed, including in areas that present challenging conditions.

Last of the reef netters: An Indigenous, sustainable salmon fishery
- Reef net fishing is an ancient, sustainable salmon-harvesting technique created and perfected by the Lummi and other Coast Salish Indigenous people over a millennium.
- Rather than chasing the fish, this technique uses ropes to create an artificial reef that channels fish toward a net stretched between two anchored boats. Fishers observe the water and pull in the net at the right moment, intercepting salmon as they migrate from the Pacific Ocean to the Fraser River near present-day Washington state and British Columbia.
- Colonialism, government policies, habitat destruction, and declining salmon populations have separated tribes from this tradition. Today, only 12 reef net permits exist, with just one belonging to the Lummi Nation.
- Many tribal members hope to revive reef net fishing to restore their cultural identity and a sustainable salmon harvest but face difficulties balancing economic realities with preserving what the Lummi consider a sacred heritage.

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.

New study pushes for protection of one of Africa’s ‘least understood treasures’
- A new study reveals the extent of a tropical water tower in Angola, which performs the same role as snow-capped mountains in the Northern Hemisphere.
- The Angolan Highlands Water Tower contains peatlands and freshwater lakes that supply major rivers in the region, and the wildlife-rich Okavango Delta in Botswana.
- Despite this vital hydrological role, the water tower currently has no formal protection.
- The team behind the study hopes it will help to strengthen the case for recognition of a vast portion of the water tower as a Ramsar Site of International Importance.

‘We just want to be left in peace’: In Brazil’s Amazon, soy ambitions loom over Indigenous land
- Deforestation is surging around Indigenous reserves in Brazil’s agricultural heartland, threatening one of the last stretches of preserved rainforest in the region.
- The destruction is trickling into protected areas too, including Capoto/Jarina Indigenous Territory, home to Brazil’s most famous Indigenous leader.
- Indigenous advocates blame land speculation on the back of plans to pave a stretch of the MT-322 highway, which runs across the Capoto/Jarina and Xingu Indigenous Park.
- Indigenous people worry the road will ease access into their territories, opening them up to land-grabbers, wildcat miners and organized crime groups.

Dam-building on Mekong poses risk to regional industries, report says
- A new report from WWF highlights how vital regional supply chains that rely on a healthy and connected Mekong River are undermined by hydropower development.
- Recent decades have seen scores of hydropower dams built on the Mekong River system, including 13 large-scale projects spanning the river’s mainstream channel, with hundreds more either planned or under construction.
- The report looks at how the economic value of hydropower in the Lower Mekong Basin measures up against its high economic trade-offs for five key sectors that underpin regional economies.
- The report provides recommendations for governments, investors and businesses to understand the true cost of hydropower and mitigate the inevitable risks they face over the decades to come.

Java farmers displaced by dam remain treading water after decades
- Farmers displaced by Indonesia’s Jatigede Dam have been forced to find new livelihoods or move to different regions of the archipelago.
- Many families were paid the equivalent of just 50 U.S. cents per square meter of land at the time, or 4.5 cents per square foot, as land acquisition accelerated in the 1980s.
- Indonesia’s second-largest dam is about to commence operation as a 110-megawatt hydroelectric plant, in addition to providing irrigation water for around 1 million farmers.

Nepal’s water hyacinth helps exotic fish invade, harming native species: Study
- Exotic fish species such as Nile tilapia and glassfish were introduced by humans to Pokhara, Nepal’s Lake City for various reasons, and they compete with and prey on native fish species.
- A study suggests that water hyacinth, an invasive plant species, could be helping exotic fish species in Pokhara’s lakes to invade the lakes and reduce the diversity and abundance of native fish species.
- The researchers suggest that urgent conservation action is needed to control the spread of both water hyacinth and exotic fish species, and to protect the native fish species and the ecosystem of the lakes.

To keep track of salmon migrations in real time, First Nations turn to AI
- Partnering with First Nations, a new interdisciplinary study proposes harnessing artificial intelligence and computer-based detection to count and produce real-time data about salmon numbers.
- Monitoring their population when they return to the rivers and creeks is crucial to keep tabs on the health of the population and sustainably manage the stock, but the current manual process is laborious, time-consuming and often error-prone.
- Fisheries experts say the use of real-time population data can help them make timely informed decisions about salmon management, prevent overfishing of stocks, and give a chance for the dwindling salmon to bounce back to healthy levels.
- First Nations say the automated monitoring tool also helps them assert their land rights and steward fisheries resources in their territories.

More action needed to protect freshwater ecosystems, report says
- A recent report from the international conservation NGO WWF argues that freshwater ecosystems are too valuable to go overlooked as new conservation policies are created.
- Freshwater underpins global food security, the economy and public health, putting the total value of water in 2021 at around $58 trillion, or 60% of the global GDP, the report estimates.
- WWF urged governments to revitalize efforts to conserve 30% of rivers, lakes and wetlands by 2030 and for the private sector to develop better risk assessments that eliminate pollution from their supply chains and consider how they contribute to water scarcity.

Oil firm Perenco eyes new blocks in DRC amid criticism of its track record
- Oil multinational Perenco has bid on two new oil blocks being auctioned off by the government of the Democratic Republic of Congo.
- Perenco operates the country’s only oil production facilities, at Muanda, near the mouth of the Congo River.
- Local and international critics accuse the oil company of polluting the environment, affecting fishing and farming, as well as residents’ health; the company denies this.

Fishing ban extension raises hopes for iconic Amazon pink river dolphin
- The Amazon river dolphin, or boto, is an integral feature of the rainforest’s biodiversity and culture, and is central to several Indigenous tales.
- Even though the dolphin isn’t fished for human consumption, it’s become endangered over the decades because fishers use its flesh as bait for catching piracatinga catfish.
- The Brazilian government earlier this year renewed a moratorium on fishing of piracatinga, first imposed in 2014, in the hope of saving the dolphin, but experts say fishers have just been ignoring the rule.
- The measure became even more relevant in October following the detection of more than 100 dead dolphins in an Amazon lake — experts suspect that the deaths are directly linked to the extreme drought affecting the region.

Conservationists condemn Nepal proposal to allow hydropower in protected areas
- The Ministry of Forest and Environment has proposed a new procedure that would allow large-scale hydropower development inside protected areas, with fewer environmental safeguards and more legal loopholes.
- Conservationists and legal experts have criticized the proposal as going against the Constitution and the National Parks and Wildlife Conservation Act as well as risking the biodiversity and ecosystem services of Nepal’s protected areas.
- They have also warned that the proposal could undermine the balance between development and conservation and expose the country to more climate change impacts such as floods and landslides.
- The Department of National Parks and Wildlife Conservation has defended the proposal as documenting the existing practices and bolstering the balance, not upsetting it.

Muddied tropical rivers reveal magnitude of global gold mining boom: Study
- A new study reveals that 59,000 kilometers, or nearly 37,000 miles, of tropical rivers have been damaged by mining, based on 7 million measurements taken from satellite images spanning four decades.
- The new study reveals a runaway river mining boom starting in the mid-2000s, largely caused by a tremendous spike in gold prices since the 2007-2008 financial crisis. Since then, the price of gold — an element which accounts for 90% of river mining in the tropics — has only gone up.
- An estimated 5-7% of the world’s large tropical rivers are considered severely affected by sediment from river-mining activities, with 173 large rivers impacted in the global tropics.
- Up to a third of global freshwater fish species are found in tropical rivers. Mining, much of it illegal or informal, seriously impacts both human and natural communities in numerous ways. Sediment traps aquatic life in dense, cloudy, muddied water, with sunlight unable to reach plants and fish.

Tropical lakes are carbon super sinks, even more than forests, study shows
- Research shows that Amazonian water bodies capture 39% more carbon per unit area than the rainforest itself.
- The research also revealed that lakes and rivers located in tropical regions with preserved forests sequester 10% of the carbon in these locations.
- The study shows the importance of preserving wetlands against climate change, the researchers say.

For International Youth Day, three youth conservation success stories
- This Saturday is International Youth Day, a day established by the U.N. to draw attention to youth issues worldwide.
- This year celebrates youth developing the “green skills” needed to shift the world into one that is environmentally sustainable and climate-friendly.
- In recognition of the international day, Mongabay spoke with three youths worldwide who initiated successful environmental restoration organizations in their communities.

Rio de Janeiro’s defender of mangroves
- Guanabara Bay in Rio de Janeiro has suffered for decades from inefficient sewage treatment, oil spills and mangrove deforestation.
- For more than 30 years, biologist Mario Moscatelli has been fighting to reverse this process and revitalize the landscape.
- For denouncing corruption, environmental crimes and government inaction, he faced intimidation and even death threats.

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

The endless struggle to clean up Rio de Janeiro’s highly polluted Guanabara Bay
- Once a nursery for marine life, Guanabara Bay in Rio de Janeiro is now dying from the dumping of thousands of liters of sewage into its waters; artisanal fishers now survive by picking up the garbage that floats in the bay.
- Faced with failed promises of de-pollution by the government, civil society organized itself, creating areas of environmental protection and pressuring the companies responsible for basic sanitation in the state, which is still deficient today.
- On the shores of the Rodrigo de Freitas lagoon, a biologist started replanting the mangroves; life returned and the site has become a model of what can be done to save the Guanabara Bay.

How biological surveys prevent destructive dams in the Balkans
- Over 3,000 hydropower dams are proposed to be built in the next few years on Balkan rivers.
- A conservation research and advocacy project says this number is too high, due to such dams’ likely detrimental effects on fragile freshwater ecology, and argues that permits granted to hydropower companies do not take biological richness adequately into account.
- The Balkan country of Albania agreed with them recently, using the group’s data as part of its decision to cancel a giant dam project proposed for the Vjosa River, and instead named the area a national park.
- Mongabay visited the group’s latest biological survey of the Neretva River in Bosnia-Herzegovina and shares this new video report.

Offshore oil plans in Brazil threaten South America’s largest coral reef
- The Parcel de Manuel Luís coral reef, off the coast of northeastern Brazil, is a vital habitat for several species, including 53 at risk of extinction.
- Despite vetoes from Brazil’s environmental regulator, the local government is seeking to give the go-ahead to oil drilling projects in this part of the Pará-Maranhão Basin.
- Oil drilling in the region also poses a threat to the longest continuous stretch of mangrove in the world, which runs from the Maranhão coastline to the northern state of Amapá, in the Amazon.

Clean me a river: Southeast Asia chokes on Mekong plastic pollution
- New research shows that the drift of microplastics from the Mekong River to the coastlines of countries around the South China Sea depends on variable factors, including seasonal changes in winds and ocean currents.
- The Philippines is most exposed to plastic waste that mainly drifts from the Mekong River to the sea during the monsoon season, with 47% of the stranded particles ending up on its coast, followed by Indonesia at 24%, Vietnam at 17%, and Malaysia at 8%.
- Environmental advocates say the findings of this study underscore the importance of international cooperation in combating plastic pollution, which harms marine biodiversity and coastal economies.

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?

Death of rare male gharial in Nepal highlights conservation crisis
- A male gharial, a critically endangered crocodilian, was found dead in Nepal’s Chitwan National Park, entangled in a fishing net and hook.
- Male gharials are vital for the survival of the species, which has a skewed sex ratio and faces threats from fishing, habitat loss, and poaching.
- Park officials are trying to boost the male population by incubating eggs at a certain temperature, but critics question the effectiveness and sustainability of this approach.

Nepal’s rhinos are eating plastic waste, study finds
- A study found plastic waste in the dung of one-horned rhinos in Nepal’s Chitwan National Park, which could harm their health and survival.
- The plastic waste comes from the rivers that flood the park during monsoon season, as well as from visitors who litter the park.
- The study suggested that the government and its conservation partners should conduct clean-up programs and implement sustainable waste management plans to protect the rhinos, which are a vulnerable species.

Dam-building spree pushes Amazon Basin’s aquatic life closer to extinction
- A recent study looking at 343,000 kilometers of waterways along 6,000 rivers across the Amazon Basin highlights the importance of free-flowing rivers to migratory species of fish and turtles, as well as river dolphins.
- More than 20 species are threatened by the construction of hydroelectric dams on long-distance rivers, considered to be key corridors for biodiversity.
- The study’s researchers identified 434 dams that have either been built or are currently under construction across the whole of the Amazon Basin, and a further 463 proposed dams that are in various stages of planning.
- One of the proposed dams on the Tapajós River would leave at least four pods of river dolphins isolated from one another, leaving them facing a similar fate to the tucuxi river dolphins impacted by similar projects on the Madeira River and today threatened with extinction.

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

Seeking environmental DNA in Himalayan rivers: Q&A with Adarsh Man Sherchan
- Conservation geneticist Adarsh Man Sherchan is one of the leading experts keeping track of the impacts that Nepal’s dozens of dams are having on freshwater species.
- The Himalayan country has more than 120 hydroelectricity plants, many of which were built without prior aquatic biodiversity assessments.
- With advances in assessment technologies, notably environmental DNA (eDNA), and a growing cohort of trained experts like Sherchan, there’s a greater focus on identifying and mitigating the impacts of dams on river life.
- In an interview with Mongabay, Sherchan talks about why eDNA is a gamechanger for monitoring species, the process of getting eDNA samples from rivers, and why jeans and flip-flops are a no-go for fieldwork.

Expedition catches Amazon river dolphins to help save this iconic pink species
- In December, researchers gathered extensive data on a population of Amazon river dolphins in the Amanã Sustainable Development Reserve in the Brazilian state of Amazonas.
- They fitted some of the dolphins with radio transmitters to help map their preferred zones and identify priority regions for species protection.
- At the top of the food chain, the river dolphins play important roles as regulators of Amazonian river life and as environmental indicators for potential zoonoses.
- Hydroelectric dams, fishing, and contamination from mining pose the greatest threats to the species across its range.

Fishers confirm scientists’ warning: Brazil’s Belo Monte dam killed off the river
- Seven years after the Belo Monte hydroelectric plant went into operation, fishers confirm what scientists have been verifying in studies: the fish have disappeared from this stretch of the Xingu River.
- According to Brazil’s Public Prosecutor’s Office, the construction of the dam caused the direct deaths of more than 85,000 fish, equivalent to 30 metric tons, between 2015 and 2019.
- The loss of fish has reverberated up the food chain, with local fishing communities no longer able to make a living that generations before them took for granted.

Award-winning community group in Sumatra cleans up lake
- A group of locals have since 2013 tried to clean up the trash pooling in Lake Sipin in the Sumatran province of Jambi.
- Their efforts have received national attention, with their leader, Leni Haini, awarded the country’s highest environmental award in 2022 by the government.
- Indonesia has announced a plan to restore 15 lakes (Sipin isn’t included) across the country by 2024, citing their high degree of degradation, chiefly sedimentation, which has resulted in their rapid shrinking and a decline in the biodiversity they host.
- These lakes are crucial in supporting the livelihoods of millions of Indonesians, serving as a source of freshwater, a form of flood control, and a site for fish-farming and tourism.

Conservationists aim to save critically endangered European eels on Italy’s Po River
- European eels (Anguilla anguilla) are critically endangered, their population having plummeted by 97% since 1980.
- Illegal fishing, dams and other barriers to their migration, droughts, pollution and habitat changes are putting the eels’ survival at risk.
- These eels reproduce once in their lifetime, only in the Sargasso Sea, where they die. Their unique lifecycle and migratory pattern further complicates conservation efforts.
- In Italy’s Po River Basin, researchers are working to conserve eels through interventions including the construction of fish passages to defragment rivers, reproduction in captivity and teaching fishers to recognize and release the likeliest breeders.

Residents of southeast Alaskan town debate mine that’s bound to change region
- After years of debate, a proposed mine in southeast Alaska near the Chilkat River has a permit to dig an exploratory tunnel and release wastewater.
- The mine has become a divisive topic in the town of Haines, where the Chilkat River sustains the region’s thriving fishing industry.
- Some residents are concerned about how the project could impact salmon in the river and their fishing jobs.
- Others believe the mining companies running the project will be responsible when it comes to protecting the river, while providing jobs in mining.

Greater Mekong proves an ark of biodiversity, with 380 new species in a year
- Scientists described 380 new-to-science species from the Greater Mekong region of Southeast Asia between 2021 and 2022.
- Researchers working in Cambodia, Laos, Myanmar, Thailand and Vietnam identified 290 plant, 19 fish, 24 amphibian, 46 reptile and one mammal species, including a thick-thumbed bat, a color-changing lizard, and a Muppet-looking orchid.
- However, many of these species already face the threat of extinction due to human activity, prompting advocates to call for increased protection of their habitats by regional governments.
- The most urgent threats to the region’s wildlife and habitats include the construction of hydropower dams, climate change, illegal wildlife trade, and loss of natural habitats.

As tourism booms in India’s Western Ghats, habitat loss pushes endangered frogs to the edge
- India’s Western Ghats, a global biodiversity hotspot, is home to many endemic and endangered species of amphibians, some of which are new to science and others suspected of lying in wait of discovery.
- Deforestation due to infrastructure and plantation expansion in the southern Western Ghats threaten the region’s amphibian species, many of which have highly restricted habitats.
- Adding to their woes is an increased risk of landslides in parts of Kerala due to erratic, heavy monsoon rains and erosion due to loss of forest.
- To save them, experts are calling for a systematic taxonomic survey of amphibians in the region and for legal protection of endangered species.

Second chance for Lula as controversial Amazon dam goes up for renewal
- In the biological and cultural hotspot of the Volta Grande in Brazil’s Amazon, Indigenous communities and scientists have teamed up to monitor the impacts of the Belo Monte hydroelectric project, one of the biggest in the world.
- The dam complex has diverted 80% of the Xingu River’s water flow, significantly affecting the aquatic life in the Volta Grande river bend and pushing the entire ecosystem toward collapse, along with the local communities who rely on it.
- The complex’s environmental license, which lasts six years and dictates the amount of water flowing through Belo Monte, is currently up for review by the federal environmental protection agency, IBAMA.
- President Luiz Inácio Lula da Silva played a key role in pushing for the construction of Belo Monte, and now, back in power, can influence a new path for the environment and local communities, activists say.

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

On the border of Colombia and Venezuela, illegal gold mining unites armed forces
- On the border between Colombia and Venezuela, just a few kilometers from Colombia’s Guainía department, illegal mining shakes the region’s economy while devastating the environment. The absence of the government is obvious.
- According to witnesses and photographs, the areas around Yapacana Hill are full of improvised billiard halls, restaurants, ice cream shops, brothels, grocery stores, clinics and even nurseries; this is all occurring under the strict control of Colombia’s National Liberation Army and FARC dissidents.
- In a 2020 study, a Venezuelan organization called SOS Orinoco revealed the massive scale of the illegal mining in Yapacana: In that year, mining affected a total of 2,035 hectares (about 5,029 acres), an area equivalent to about 1,884 soccer fields that is visible in satellite images.

Crud-to-crude: The global potential of biofuels made from human waste
- Creating liquid biofuels from human waste shows promise as a way to meet one of alternative energy’s greatest challenges: reducing the transportation sector’s heavy carbon footprint. The good news is there is a steady supply stream where waste is treated.
- Humanity produces millions of tons of sewage sludge annually via wastewater treatment. Existing disposal methods include landfilling, application on agricultural land, and incineration; each with social and environmental consequences.
- Harnessing the carbon-rich potential of sludge as a transportation fuel for planes, ships and trucks is part of a drive toward zero waste and creating a circular economy, say experts. A host of projects are underway to prove the effectiveness of various methods of turning all this crud into biocrude.
- Some techniques show promise in lab and pilot tests, but large-scale industrial plants have yet to be built. Using pollutant-laden sewage sludge as a biofuel comes with its own environmental concerns, but lacking a silver-bullet solution to the human waste problem, it could be part of a suite of best alternatives.

‘It gives life’: Philippine tribe fights to save a sacred river from a dam
- Each year, members of the Dumagat-Remontado tribe gather at the Tinipak River to observe an Indigenous ritual to honor their supreme being and pray for healing and protection.
- This year, the rite had an additional intention: to ward off an impending dam project they fear will inundate the site of the ritual.
- The Kaliwa Dam, part of a program aimed at securing a clean water supply for the Manila metropolitan region, is already under construction and scheduled to go online in 2027.
- The project has faced resistance from civil society groups as well as many of the Dumagat-Remontado, who say they fear it will cause both environmental and cultural damage.

Spamming streams with hatchery salmon can disrupt ecosystems, study finds
- In a new study, researchers found that releasing hatchery-bred native masu salmon into freshwater streams in Hokkaido, Japan, destabilized the local ecosystems.
- Overall, the study found that the total number of fish, and number of different species, both declined in the long term due to greater competition for resources like food and preferred feeding spots.
- Masu salmon populations also did not increase in the long term, the research found.
- With hatchery releases increasing in many areas — and for many species — the findings add to the ongoing debate over their wider effects on wild fish populations.

‘Chasing giants’: Q&A with megafish biologist and author Zeb Hogan
- Earth’s freshwater ecosystems are among the most at risk from human-induced threats including overfishing, dam building, pollution and climate change.
- But biologists know relatively little about the animals that live in the murky depths of our rivers and lakes, perhaps least of all about some of their largest inhabitants.
- In a new book, fish conservation biologist Zeb Hogan teams up with journalist Stefan Lovgren to get to the bottom of a curious question: What is the world’s largest freshwater fish?
- An exploration of the world’s freshwater ecosystems from Australia to the Amazon, “Chasing Giants” also looks into the range of threats giant fish face the world over and what scientists, policymakers and the public can do to support their conservation.

A Guatemalan town fights to bar gold mining and save its waters
- Over the last 25 years, local community members have repeatedly rejected a gold mining project on the border of Guatemala and El Salvador for lack of environmental compliance.
- The government of Guatemala has approved the extension of the Cerro Blanco project, which, under new ownership is planned to switch from underground to open-pit mining.
- Worried that mining is contaminating waters and affecting biodiversity, the community of Asunción Mita held a referendum last September, voting to reject the project, but it hasn’t yet obtained recognition from the state.
- While mining is on hold, awaiting a final verdict on the referendum, natural ecosystems and watercourses are bouncing back with life.

In a Bolivian protected area torn up for gold, focus is on limiting damage
- Artisanal gold mining by local cooperatives abounds in protected areas across Bolivia, in particular the Apolobamba highlands near the border with Peru.
- The mining boom here began in the late 1990s, and since then the cooperatives have continued to use mercury amalgamate the gold.
- There are worries over mercury contamination as well as the diversion of river flows away from wetlands to the mines.
- NGOs working with the cooperatives say the local miners are keen on making their operations more sustainable, but that the cost and lack of government support are hurdles to achieving this.

Mouth of the Amazon oil exploration clashes with Lula’s climate promises
- State-owned Petrobras has requested a license to investigate an oil site in a region in the north of Brazil where the Amazon River meets the Atlantic Ocean.
- The region is home to swathes of mangroves and coral reefs that environmentalists say are highly biodiverse and fundamental to local communities.
- Experts demand that Brazil’s environmental agency reject the license, saying the government hasn’t conducted the required detailed studies to assess the potential impact.
- Critics warn that pursuing fossil fuels contradicts President Luiz Inácio Lula da Silva’s vows to adopt a renewable energy strategy and clashes with global climate change guidelines.

Meet the 2023 Goldman Environmental Prize Winners
- This year marks the 34th anniversary of the prestigious Goldman Environmental Prize, which honors one grassroots activist from each of the six inhabited continents.
- The 2023 prize winners are Alessandra Korap Munduruku from Brazil, Chilekwa Mumba from Zambia, Delima Silalahi from Indonesia, Diane Wilson from the U.S., Tero Mustonen from Finland, and Zafer Kızılkaya from Turkey.

Power of traditional beliefs lies at the heart of an anti-mine campaign in PNG
- A newly published study published explores the important role that traditional Papua New Guinean beliefs play in an ongoing campaign against a copper and gold mine on a tributary of the Sepik River.
- Critics say the controversial mine project could potentially pollute one of the most biologically and culturally diverse places on Earth, while supporters point to potential development benefits.
- The Save the Sepik campaign against the mine harnesses traditional governance structures and beliefs, acknowledging the spirits of ancestors, the land and river, in a declaration that has become a rallying cry for the campaign.
- The campaign’s success so far — licenses haven’t been awarded for the mine project — is part of a growing global movement that acknowledges the close relationship some communities have with a sentient environment.

Robust river governance key to restoring Mekong River vitality in face of dams
- Billions of cubic meters of Mekong River water are now harnessed behind dams in the interests of power generation, severely affecting crucial physical and biological processes that sustain the river’s capacity to support life.
- As the pace of hydropower development continues to pick up across the river basin, cracks in the region’s dated and limited river governance systems are increasingly exposed.
- Major challenges include the lack of formal, legally binding regulations that govern development projects with transboundary impacts, and a legacy of poor engagement with riverside communities who stand to lose the most due to the effects of dams.
- Experts say that open and honest dialogue between dam developers and operators is needed to restore the river’s natural seasonal flow and ensure the river’s vitality and capacity to support biodiversity and natural resources is sustained.

As hydropower dams quell the Mekong’s life force, what are the costs?
- The Mekong River is one of Asia’s longest and most influential waterways, sustaining extraordinary species and biodiverse ecosystems and providing nutrition for millions via its fertile floodplains and unparalleled fisheries.
- But over the past few decades, the construction of hydropower dams has undermined the river’s capacity to support life: more than 160 dams operate throughout the Mekong Basin, including 13 on the river’s mainstream, with hundreds more either planned or under construction.
- Besides severing fish migration routes and natural sediment transport throughout the river system, the dams affect the river’s natural seasonal ebb and flow, an ancient rhythm alongside which ecosystems have evolved.
- Communities, scientists and decision-makers now face unprecedented challenges as fish catches dwindle, riverbanks erode, ecosystems collapse and the delta inexorably sinks.

RSPO suspension of Brazil palm oil exporter tied to Mongabay land-grabbing report
- Agropalma, the only Brazilian company with the sustainability certificate issued by the Roundtable on Sustainable Palm Oil (RSPO) — a members organization including palm oil growers, traders, manufacturers, retailers, banks, investors and others — has had its certificate “temporarily suspended” since February.
- In December 2022, Mongabay published a yearlong investigation revealing that more than half of the 107,000 hectares (264,000 acres) registered by Agropalma in northern Pará state derived from fraudulent land titles and even the creation of a fake land registration bureau. Part of the area overlaps ancestral land claimed by Indigenous peoples and Quilombolas — descendants of Afro-Brazilian runaway slaves — including two cemeteries, which is at the center of a seven-year legal battle led by state prosecutors and public defenders.
- Just a few weeks after the publication of the investigation, representatives from the certifiers contacted Quilombola leaders “to understand the denouncements” published by the report, they went to the region and carried out audits in all affected communities; soon after, IBD Certifications Ltd. suspended Agropalma’s RSPO certificate.
- Assurance Services International (ASI), which evaluates the work of certifiers, confirmed that “the report was a reason for ASI to conduct a compliance assessment to IBD, the certifier of Agropalma, at the Certificate Holder’s premises.” University professors hired by ASI as local experts also cited the Mongabay investigation and this reporter when they contacted other key sources quoted in the report, as shown in email correspondence seen by Mongabay.

Human migration to Nepal’s tiger capital adds to conservation challenges
- Chitwan district in central Nepal is home to the eponymous national park that’s come to symbolize the country’s success in growing its tiger population.
- But the district’s human population is also growing, at a rate far higher than the national average, driven by migrants seeking better health services and other urban amenities.
- Conservationists have raised concerns that the growing human presence in the area will pose additional challenges to conservation efforts and put a strain on natural resources such as forests, rivers and land.
- Some warn of an increase in human-tiger conflict, especially involving migrants who don’t share the same traditional knowledge that Indigenous residents have of coexisting alongside the big cats.

For rescued rhino calves in Nepal, return to the wild is a fraught option
- Conservation officials in Nepal are considering what to do with three juvenile rhinos rescued from the wild after being separated from their mothers.
- One option is to return them to the wild in a national park or wildlife reserve with suitable habitat — but with the risk that they could fall prey to tigers. Rhino translocations in Nepal have a poor record — only 38 of 95 rhinos transferred from Chitwan to Bardiya National Park survive, with the rest killed by poachers or farmers.
- That leaves a third option on the table, which is to gift the animals to a foreign country, as part of Nepal’s “rhino diplomacy,” which would leave the young animals facing a lifetime in human company.

Brazil tackles illegal miners, but finds their mercury legacy harder to erase
- As the details of the humanitarian crisis in the Yanomami Indigenous Territory unfold amid action to remove illegal miners, mercury left by the rampant gold mining in the area will remain a lingering toxic legacy.
- A range of solutions is needed to support communities at risk, monitor the situation, assist in the remediation of forests, and prevent continued pollution, experts say.
- New technologies that can filter mercury are under development and testing, but are still far from being viable solutions at the scale that the problem inside the Amazon calls for.

Loss of wetlands threatens South Sumatra’s rich fish-preserving tradition
- Rural communities in South Sumatra, an Indonesian province that’s two-fifths wetlands, have long relied on catching freshwater fish as a source of livelihood.
- The region is renowned for its variety of preserved fish products, which are sold throughout Indonesia.
- However, the wetlands are disappearing at a rapid rate, filled in to make way for oil palm plantations and highways, and threatening the region’s long-running fish-preserving tradition.
- Today, most of the freshwater fish processed here comes from fish farms, and include exotic species not native to the region, which some say doesn’t taste as good as the traditional species.

A freshwater giant is a boon to Bolivian fishers, but an unknown for native species
- Paiche or arapaima (Arapaima gigas) was introduced in Bolivia in 1976 by accident from Peru, and though initially rejected as an exotic species, is today prized by local fishers as a boon to the economy.
- There’s no research on the potential damage caused to riverine ecosystems in the Bolivian Amazon region due to the arrival of paiche, but native fish species have disappeared in some areas where the freshwater giants thrive.
- The Bolivian government has not classified paiche as an invasive species, with some official studies recommending controlling rather than eradicating its population.
- Paiche fishing has also been encouraged as an economic boon to rural communities, where the species accounts for up to 70% of fishers’ catch.

Bangladesh bans suckermouth catfish in light of threats to native fish species
- Considering its aggressive breeding nature and the threats the species poses to native fish populations, the Bangladesh government has recently banned suckermouth fish.
- The suckermouth catfish is mainly an aquarium species that was imported into Bangladesh in the 1980s as an ornamental fish and later introduced into water bodies that are home to the country’s main sources of native fish.
- However, in recent years, the number of suckerfish has increased manifold as local fish species have decreased.
- Earlier, in 2002, Bangladesh banned two other fish species: African catfish and piranhas.

Illegal mines and “floating towns” on the Puré River leave uncontacted Indigenous peoples at risk
- The Yurí-Passé are at risk of coming into contact with illegal miners and drug traffickers, which violates their right and deliberate decision to live in isolation from the Western world.
- According to one study, mercury levels in the blood of communities living along the Caquetá river and its tributaries, such as the Puré River, are much higher than the average.
- Although the Puré River area is located in a protected area, mining activity has increased following a number of threats made against park rangers and an arson attack on a cabin belonging to Colombia’s Natural National Parks authority (PNN) by FARC dissidents. Despite military operations, mining activities continue, with dozens of dredgers thought to be operating on the river.

Element Africa: Lead poisoning, polluted rivers, and ‘calamitous’ mining regulation
- More than 100,000 Zambian women and children are filing a class action lawsuit against mining giant Anglo American for decades of lead poisoning at a mine they say it controlled.
- Illegal gold mining in Ghana is polluting rivers that local communities depend on for water for drinking, bathing and farming.
- A legal case against a village head who allegedly sold off the community’s mining license to a Chinese company has highlighted what analysts call the “confusing” state of mining regulation in Nigeria.
- Element Africa is Mongabay’s bi-weekly bulletin rounding up brief stories from the extractives industry across Africa.

Banned but abundant, gillnets pose main threat to Bangladesh’s river dolphins
- Bangladesh is home to around 2,000 Ganga River dolphins and 6,000 Irrawaddy dolphins, found mostly in the Sundarbans, the world’s largest mangrove forest.
- Both species, considered threatened on the IUCN Red List, run a high risk of entanglement in the gillnets used by local fishers.
- Gillnets are banned in Bangladesh, but remain popular among local fishers, with the government unable to crack down on their use.
- To conserve the freshwater dolphins, the government has embarked on a 10-year action plan that includes declaring more areas as dolphin sanctuaries and raising awareness among fishers.

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.

Series of small dams pose big cumulative risk to Amazon’s fish and people
- Small hydropower plants and small-scale fish farming in the Brazilian Amazon basin are often thought to cause negligible environmental harm, yet a new study reveals their cumulative damage is greatly underestimated and can be more impactful than large dams.
- Dwindling fish populations caused by the construction of thousands of small dams has impacted the livelihoods of millions of Indigenous and riverside people who depend on fishing for food, income and culture.
- Small hydropower plants and aquaculture farming are encouraged through economic incentives, simple licensing procedures, and loose requirements for environmental impact assessments before construction.
- More than 350 dam proposals in the Amazon basin are under consideration and 98 medium-sized dams will be prioritized in Brazil as of next year, ensuring the construction of hydropower plants will continue.

Brazilian archbishop is threatened for defending Indigenous peoples — even during Mass
- Dom Roque Paloschi, president of the Indigenous Missionary Council (CIMI) and archbishop of Porto Velho in the state of Roraima, Brazil, has been under attack because he denounced Indigenous people’s rights violations.
- It has always been risky to live in Amazonia and defend social-environmental issues, but Paloschi says the situation has worsened greatly in the last four years — the period that coincides with Jair Bolsonaro’s administration.
- In 2021, 355 attacks against Indigenous people were reported in Brazil — the most since 2013, according to a CIMI report.

In Brazil’s Amazon, Quilombolas fight major palm oil firm for access to cemeteries
- Areas along the Acará River in northern Pará state are at the center of a six-year legal battle where Quilombolas — descendants of Afro-Brazilian runaway slaves — accuse Agropalma, the country's second-largest palm oil exporter, of land-grabbing over their ancestral lands, including cemeteries, as revealed by Mongabay's yearlong investigation.
- One of these areas is Our Lady of Battle Cemetery, where Mongabay witnessed in November 2021 Quilombolas celebrating the Day of the Dead for the first time in decades. They say access to the area was hampered since it became Agropalma’s “legal reserve” — the proportion of land that the Brazilian legislation obliges a private property owner to maintain in its natural state — in the 1980s.
- In this video, Mongabay exhibits what is called a “historic moment” and firsthand footage and interviews with Quilombolas going to this cemetery for the first time. This video also has impressive images of palm trees just a few steps from the graves at Livramento Cemetery, completely surrounded by Agropalma’s crops. Quilombolas accuse Agropalma of destroying three-quarters of its area to make way for its plantations; the company denies.
- “To support future lawsuits,” prosecutors in Pará state have cited the Mongabay investigation in their procedures looking into the conflicts between Quilombola communities seeking recognition of their territory and areas occupied by Agropalma.

Shadows of oil in Peru: Shipibo people denounce damage, contamination left by company
- Community members guided a team of journalists to the creeks and land of Canaán de Cachiyacu and Nuevo Sucre, in the district of Contamana in Peru’s Loreto region, to demonstrate how they have been affected by the various spills attributed to the Maple Gas oil company for over 25 years.
- Shipibo community members say that due to contaminated water, they still suffer from illnesses and their farms no longer produce crops. The contract established that the company must comply with environmental protection laws, but Perupetro confirmed that it simply abandoned its operations.
- Mongabay Latam traveled to two Indigenous communities on the banks of the Ucayali River and listened to the concerns of their residents regarding the serious environmental impact that they claim was caused by the operations in Block 31-B and Block 31-E.
