Urban water quality pose challenges to low-income communities in Sri Lanka’s commercial capital
- Most urban poor living in Colombo, Sri Lanka’s commercial capital, rely on pipe-borne water for their daily needs.
- Many fresh water sources have become contaminated over a period of 20-25 years due to human interventions and environmental factors.
- As extreme heat impacts the island, water scarcity may force city people to use alternative or less protected water sources, researchers say.
- Studies indicate that other water sources, such as wells and community water schemes, are more likely to show bacteriological non-compliance.

Climate change parches Puerto Rico and Jamaica in rare early wet season drought
A severe drought that has parched the Caribbean since May 2026 was fueled by human-induced climate change, according to a recent study. The rapid analysis was released by World Weather Attribution (WWA), a global network of researchers who analyze the influence of climate change in extreme weather events. In the Caribbean, the wet season runs […]
A sea cucumber venture in Zanzibar seeks to balance business and conservation
- For decades, conservationists have argued that protecting nature cannot rely indefinitely on donor funding. To endure, conservation efforts must generate enough economic value to sustain themselves.
- That search for sustainable financing has prompted governments, investors and conservation organizations to experiment with models that seek to align commercial returns with environmental protection.
- On Tanzania’s Pemba Island, a company called Asili is betting that sea cucumber ranching can do both. The venture is building the infrastructure needed to cultivate and process sea cucumbers for sale while supporting the restoration and protection of marine ecosystems.
- Yet, significant questions remain. Can enough sea cucumbers be produced to make the business commercially viable? Can profits be shared equitably with local communities? And can a model built around conservation and commerce truly deliver on both promises?

Brazil relaxes Belo Monte water rule amid El Niño-fueled Amazon drought risk
Brazilian authorities have temporarily relaxed an environmental rule for the Belo Monte hydropower plant on the Xingu River in the northeastern Amazon. The change comes in anticipation of another potentially severe, El-Niño-fueled dry season. Under the temporary measure, Belo Monte’s operator Norte Energia can cut the flow of the dam’s 119 square-kilometer (46 square-mile) intermediate […]
Indigenous water systems gain ground as climate pressures intensify in Bolivia
- When a 2022 drought hit Bolivia’s Ascensión de Guarayos, restoring traditional paúros helped the community survive after the municipal reservoir ran dry.
- The youth-led effort to revive paúros has grown into a broader conservation project, including a legally protected urban ecological corridor.
- The initiative is part of a global trend to restore Indigenous water systems as low-cost, climate-resilient solutions to growing water scarcity.
- Experts say blending traditional and modern approaches can strengthen water security — but only if local communities lead and retain control.

Polluted waterways and water shortages complicate the fight against Ebola in the DRC
- Safe access to water is scarce across parts of Ituri province, which is the epicenter of the Ebola outbreak in the Democratic Republic of the Congo.
- The Ebola virus is transmitted through direct contact with bodily fluids like blood, saliva and urine of an infected person. It is, therefore, crucial, in order to prevent the spread of the disease, to be able to wash regularly. Response teams also need access to water to clean equipment and areas used by patients.
- People sometimes use taps and showers installed at Ebola treatment centers to collect water, potentially increasing contact between healthy and infected people.
- Artisanal and small-scale mining in the region also put pressure on local water resources, by turning some waterbodies muddy.

Angola’s peatlands highly underestimated, new study suggests
- New research mapping out the Angolan Highlands Water Tower (AWHT), a stretch of elevated plateau spanning 380,382 km², finds that a significantly larger portion of the region hosts peatland than previously thought.
- The findings show that the AWHT, named thus because it receives and regulates vast amounts of rainwater, and because it feeds important freshwater systems across southern Africa, is also a critical carbon sink.
- The research can inform national carbon policies and conservation strategies for these peatlands which store thousands of years-old carbon, experts said.
- The biggest threats to the AHWT’s peatlands are human-made including slash and burn agriculture and the unsustainable use of peat — partially decomposed plant material that builds up in waterlogged soils — which result in the release of CO2.

A mine polluted a Zambian river in 2025: Residents continue to live with the impacts
- A recent study on the ecological impacts of a tailings dam failure in Zambia’s Copperbelt Province in 2025 finds that highly toxic substances such as arsenic, lead and zinc were released into the Kafue River system.
- As a result of the spill at Sino-Metals Leach Zambia’s mine, millions of liters of acidic mining waste were released into waterways connected to the river.
- The assessment links the incident to the death of wildlife and the contamination of soils and water sources in the region.
- Sino-Metals Leach Zambia says it has initiated cleanup measures, but communities still reside on contaminated land, according to civil society organizations.

Climate shocks hit hydropower in Southern Africa, reviving interest in coal
- Prolonged droughts, especially those linked to the 2023–24 El Niño, exposed the vulnerability of Zambia and Zimbabwe’s hydropower-dependent electricity systems, triggering severe power shortages and renewing interest in coal.
- While coal is viewed as a short-term solution to stabilize electricity supplies and support industrialization, it could undermine Paris Agreement commitments, lock in carbon emissions and reduce export competitiveness as trade rules that put a cost on carbon emissions come into play.
- Households and businesses in Zimbabwe are increasingly investing in rooftop solar, demonstrating that decentralized renewable energy is becoming a practical response to unreliable grid electricity.
- Although solar power is becoming more cost-effective, limited access to finance and policies that continue to favor fossil fuels are slowing the transition to cleaner, climate-resilient energy systems across Southern Africa.

Sri Lanka prepares for impending El Niño with traditional and new approaches
- According to traditional Sri Lankan paddy farmers, long dry spells have occurred every four to seven years.
- Sri Lanka has experienced around 25-26 El Niño events from 1950 to date, out of which only three have been strong El Niño events, meteorology department officials say.
- The irrigation department has introduced new water-saving techniques such as alternative wetting and drying to preserve excess water during the forecasted dry season.
- Attempts are also being made to integrate science into decision making, but there are gaps in research due to a lack of access to information, academics say.

Costa Rica banana plantation destroyed protected wetland, complaint alleges
- A legal complaint in Costa Rica alleges that a banana plantation destroyed parts of a protected wetland in Bananito Sur, located in the Valle La Estrella district in the central province of Limón.
- Workers on the La Paz banana plantation, owned by Standard Fruit Company de Costa Rica, a subsidiary of Dole, cut down and burned vegetation, according to several complaints and court filings.
- The area is a state-recognized palustrine wetland, located inland and unconnected to the ocean or rivers. It provides breeding areas for migratory birds and helps resupply the region’s aquifers.

‘The shape of the land will change:’ South African villages resist heavy sands mine
- Communities in South Africa’s Eastern Cape are opposing a proposed heavy mineral sands mine that a South African company wants permission to operate day and night for 30 years on their communal land.
- They say the land targeted for mining is far from unused, supporting more than a 1,000 cattle, traditional medicine gathering, tourism and facilitates access to the coast and fishing.
- The villagers say that if the mine goes ahead, it will damage livelihoods, ancestral graves, biodiversity and water resources.
- The planned mine could also impact their long-running campaign to acquire commercial seaweed harvesting permits and an existing small-scale sand mining business run by a village committee.

Thai MP calls for new committee to scrutinize AI data centers’ environmental impact
- A Thai member of parliament has called for the formation of a new committee to scrutinize the development of new data centers.
- Experts have warned that Thailand needs to find a balance between economic development and the water and energy resources required to fuel data centers.
- Despite these concerns, international tech companies are spending billions of dollars on data centers in Thailand, sparking fears over water scarcity and energy infrastructure.

In Michoacán, Mexico, drying soil threatens water supplies and avocados, says study
- Avocados are grown year-round in the southwestern Mexican state of Michoacán, which exports more than 1 million metric tons of avocados annually.
- A recent study in Michoacán found that between 2001 and 2018, soils with high avocado productivity lost 38 liters per cubic meter of water annually.
- Illegal logging of high-altitude forests to accommodate new avocado plantations simultaneously depletes the aquifer, as avocado trees consume 4-5 times more water than native pines.
- If the trend continues, Michoacán’s avocado-growing areas are expected to suffer increased water stress in the short term, negatively affecting both agricultural production and drinking water access in the region.

How saline drinking water raises preeclampsia risks in coastal Bangladesh (commentary)
- Climate change and rising sea levels are driving salt water intrusion into drinking water sources in coastal Bangladesh, which research links to an increased risk of preeclampsia, a leading cause of maternal mortality.
- Rural communities lack adequate freshwater infrastructure, which means pregnant women are often forced to consume saline water, making them particularly vulnerable to the life-threatening effects of excessive sodium intake.
- To address this hidden health crisis and prevent further maternal deaths, Bangladesh’s government and partner organizations must take urgent action by subsidizing household rainwater harvesting tanks for the most vulnerable coastal families.

From rivers to mangroves, microplastics are contaminating the Amazon
- Recent studies show that microplastics are already present in a variety of Amazonian environments: Major rivers such as the Amazon, urban streams, floodplain areas and mangroves in the Amazon’s Mouth.
- In a single lake in eastern Manaus, researchers found microplastics in the intestines of half the jaraquis — the most consumed fish in Amazonas state
- The contamination is related to irregular waste disposal and lack of sewage collection and treatment, which allow household residues to flow directly into water bodies.
- This is the first story in a three-part special series on microplastics in the Amazon region; upcoming pieces will look into the effects of these particles on aquatic and terrestrial organisms.

Can ‘fog harvesting’ help solve water scarcity in Chile’s Atacama Desert?
- Communities living in Chile’s Atacama Desert, one of the driest places on Earth, look for creative ways to fight water scarcity, including “harvesting” water droplets from the foggy climate.
- Local groups erect large mesh structures that can intercept thousands of liters of water droplets per day from fog being carried by the wind. The water is used for drinking and cultivating fruits and vegetables.
- Researchers have studied the factors that increase harvesting results, including sea level, temperature, solar radiation, and wind speed.
- With more research and support for pilot programs, they say local governments could one day adopt the strategy into their water management plans.

Rivers are not just water bodies: Interview with the Waterman of Odisha
- Ranjan Panda — social ecologist, journalist and researcher — is popularly known as the Waterman of Odisha.
- Panda highlights the invisible and noneconomic losses that communities living in coastal areas deal with due to climate change.
- In this interview, he highlights how rivers should be seen beyond their two boundaries of flow; how there is a stark difference in the ways rural and urban India see rivers.

Indigenous advocates push for rights protections around AI data centers
- At a meeting of the U.N. Expert Mechanism on the Rights of Indigenous Peoples (EMRIP), Indigenous advocates called for attention to the need for AI to be developed in ways that align with Indigenous rights and priorities.
- Data centers, the infrastructure that powers AI technology, require large amounts of energy and water to operate, yet many are constructed in water-stressed regions, leading to widespread opposition among local residents.
- Many sources who spoke to Mongabay raised concerns about their land, water and food sovereignty.
- Some said they believe the infrastructure could create opportunities for Indigenous people, so long as it complies with the principles of free, prior and informed consent (FPIC) and meaningful participation, among other steps.

What will Africa’s story on ocean governance be? Interview with David Willima
- With the High Seas Treaty in force, African proposals to designate marine protected areas in international waters are taking shape.
- Maritime security expert David Willima talks about why the West African marine protected area proposal is advanced and why others still require careful coordination.
- Willima says that with the current transformation marine governance is going through, African countries need to be actively engaged in order to have a voice in global decision-making.

Sea level rise is ruining coastal Bangladesh with salty water (commentary)
- Projections indicate that Bangladesh faces an amount of sea level rise that will bring major saltwater intrusion into precious freshwater supplies, plus human health impacts, flooding and rampant erosion across coastal areas.
- Though Bangladesh did very little to cause climate change, the nation is not without answers, including the government’s Delta Plan 2100, but it is not moving quickly enough to act on them in time to avoid the worst impacts, the author writes.
- “What has been missing is not knowledge or technology, but the institutional will to treat this like the emergency that it is,” the writer argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Thai farmers fear water woes from planned LNG plant
- Farmers in Thailand’s Chachoengsao province worry a planned 600-megawatt LNG power plant could increase water shortages and air pollution in an area already facing recurring drought.
- The project is the latest chapter in an 18-year struggle by local communities, who previously helped stop the same development when it was planned as a coal-fired power station and continue to challenge it on environmental and health grounds.
- Opponents also question why the plant is needed at all, arguing Thailand already has excess generating capacity and that expanding LNG infrastructure could deepen fossil-fuel dependence while delaying a shift to renewable energy.

Women patrol Tanzania’s Pemba waters in a community-led push to protect the sea
- More than 1.8 million people live in Zanzibar, the semi-autonomous archipelago that united with Tanganyika in 1964 to form present-day Tanzania.
- Of Zanzibar’s population, roughly 550,000 people live on Pemba Island, one of its two main islands, where many households depend directly on the surrounding marine ecosystem for food, income, and livelihoods.
- Across the island, a community-led approach to marine resource management is taking root. Local communities are organized through Shehia Fisheries Committees and Collaborative Management Groups, which develop and implement rules governing the use of marine resources, including fisheries and locally managed conservation areas.
- Enforcing those rules, however, is not always straightforward. Community patrol teams often lack the legal authority needed to take action against offenders. In a largely Muslim society where marine patrols have traditionally been dominated by men, women are increasingly joining these teams to help monitor fishing activities and encourage compliance.

Six marine sanctuaries recognized as Blue Parks, four of them in Africa
- On June 16, the Marine Conservation Institute recognized six marine protected areas, three in Madagascar and one each in Senegal, Chile and Canada, as Blue Parks.
- The awards, announced at the Our Ocean conference in Mombasa, Kenya, recognize MPAs whose management is “durable, equitable and effective” at protecting marine life.
- Under the Kunming-Montreal Global Biodiversity Framework, countries agreed to protect 30% of the world’s land, freshwater and marine areas by 2030, but experts say that protection must be meaningful, not just symbolic.
- One of the common features of the awardees is the existence of some form of co-management with Indigenous peoples and local communities.

Failed promises to clean air in South Africa’s coal belt take toll on public health
- South Africa’s coal belt produces more than half of the country’s electricity, but people who live in the shadow of the power stations and mines suffer from a range of health issues linked to pollution from these facilities.
- Despite being declared a priority area for tackling air pollution nearly 20 years ago, residents and campaigners here say little has improved.
- Research by the South African Medical Research Council linked pollutants like PM 10 and sulfur dioxide (SO₂) to increased mortality risk, sinus problems, tuberculosis, asthma and other lung and respiratory issues among residents of the Highveld Priority Area, named for its high altitude.
- Activists are taking legal action to compel the government and industrial players to improve emission standards, enforce them fully and to do away with exemptions.

South America’s farms depend, in part, on a healthy Amazon
- The Amazon is not only a carbon store; it is also a major source of atmospheric moisture that helps sustain rainfall across much of South America.
- A new Nature study finds that deforestation lowers the warming threshold at which large parts of the Amazon could lose stability.
- Recent droughts, El Niño conditions, and fire risk show why degraded forests are less able to withstand climate stress and recover afterward.
- Protecting intact forests, restoring degraded areas, and reducing fire are increasingly important for climate resilience, biodiversity, and South America’s food system.

In Ecuador, an Indigenous community goes thirsty despite its two rivers
- On the banks of the Puní River’s middle basin, in the Ecuadorian Amazon, illegal mining has increased by 2,700% over seven years, contaminating the main water source for the ancestral Kichwa community of Capirona.
- Residents of Capirona say that, by 2021, the color of the Puní River started to change, turning brownish. Meanwhile, problems such as skin rashes, fungal infections and itching became frequent.
- In samples of mining ore collected by Ecuadorian authorities from an illegal mining camp on the banks of Puní, signs of mercury were found at levels far exceeding the permitted limit for this metal in agricultural soils.
- Industrial farming activity has also polluted the waters of the Shalkana River, another watercourse located within the community. Despite being surrounded by two rivers, residents of Capirona rely on two water tankers sent weekly by municipal authorities, which is enough for barely half of the families for just a few days.

A year on, Australia’s biggest harmful algal bloom continues to wreak havoc
- The largest and longest-lasting harmful algal bloom in Australia’s history, which started in early 2025, has potentially affected more than 20,000 square kilometers of ocean waters and about a third of the coasts in the state of South Australia.
- The algal bloom has devastated marine ecosystems and caused significant economic losses in the local fishing, aquaculture and tourism industries.
- As officials, researchers and communities grapple with its ecological, health and social impacts, the bloom has exposed a lack of preparedness at all levels of government for responding to future HABs.

Northern Thai residents march for action on polluted rivers. ‘This is an emergency’
- A six-day ‘peace walk’ to demand Thai officials take action regarding river pollution that has seen Thai rivers polluted with heavy metals concluded on World Environment Day.
- Health authorities in Thailand have found arsenic in two people living near the Kok River. Heavy metals have also been found in the water and fish of Kok and other rivers.
- A spokesperson for the Thai Prime Minister’s Office said the government established a working group to monitor the contamination problem in the Kok River and has been continuously coordinating with other countries.
- China, which imports rare earth oxides and compounds from Myanmar, also addressed the pollution of rivers in an online statement: “The Chinese government has always placed utmost importance on protecting the environment and ecosystem.”

Despite oil spills in Nigeria’s mangrove forests, Shell continued operations, documents show
- Documents disclosed as part of a lawsuit against UK-based oil company Shell show leadership continued operating a compromised pipeline in Nigeria’s Niger Delta despite knowing it posed a pollution risk in the surrounding coastal wetland environment.
- According to locals in Bille, a town near the pipeline, oil spills between 2011 and 2013 killed thousands of hectares of mangroves and aquatic life that rely on the wetland ecosystem, impacting people who depend on fishing.
- Shell said organized criminal gangs were responsible for the spills and that shutting down the pipeline and removing illegal connections also came with security risks.
- The Niger Delta region is a globally important biodiversity hotspot, hosting four Ramsar Wetlands and the largest mangrove forest in Africa.

Europe removes record number of dams in 2025 to restore rivers, help species
A massive slab of wartime concrete blocked the Pčinja River in Kumanovo, North Macedonia for more than 70 years. A 53-meter-long and 30-meter-wide (174 by 98 feet) structure of reinforced concrete packed with salvaged railway steel impeded the free flow of water and fish for at least 70 kilometers (44 miles) upstream. It was considered […]
Risk of saltwater intrusion into coastal groundwater spans the globe: Study
- Coastal sites throughout the world are seeing notable declines in groundwater levels, putting them at risk of saltwater intrusion, according to a new study.
- About half of drinking water and a quarter of irrigation water comes from groundwater, so this trend threatens a vital source of freshwater for humanity.
- The study authors found that more than 10% of monitored locations showed a significant years-long decline in groundwater levels, indicating a susceptibility to saltwater intrusion, which can render water unusable.
- Many large-scale studies on groundwater and saltwater intrusion are model-based, but this one analyzed data from wells across much of the world.

Who are the women sustaining luxury fishing in Brazil’s Pantanal?
- In the heart of the Pantanal wetland, women from riverine communities spend up to 12 hours a day in murky waters, surrounded by caimans and snakes, to gather live bait that feeds a multimillion-dollar fishing tourism industry.
- Sportfishing in the Pantanal generates around $20 million a year, but the gatherers receive only a few cents for each piece of bait.
- During the close season, from November to February, when fishing is banned, they are supposed to receive compensation from the state; but this season there was still no payment as of early February.
- According to government data, women make up 40% of professional fishers in Brazil’s two Pantanal states, and they do most bait collection in the biome.

Dangerous arsenic levels detected in Thailand’s Mekong mainstream for first time
- Thai authorities have detected dangerous levels of arsenic contamination in sediment from the Mekong River mainstream and three of its tributaries in the country’s north.
- The contamination has been widely linked to a surge in unregulated mining, including for rare earth minerals, upstream in Myanmar’s Shan state.
- Experts warn that toxic heavy metals could threaten aquatic ecosystems, fisheries and the livelihoods of millions of people who depend on the Mekong Basin.
- Regional coordination and monitoring remain limited, with the Mekong River Commission lacking authority over key upstream areas in Myanmar and China.

The world’s great deltas are sinking — and with them, a global food system
- The Mekong Delta is sinking. Projections indicate that 90% of this life-sustaining landform could disappear by 2100 due to human-driven factors such as groundwater pumping and sediment capture by dams, compounding the effects of sea-level rise.
- The Mekong is just one of 40 of the world’s large river deltas threatened by high subsidence rates coupled with rising sea levels, according to a 2026 global study. Among the 19 river deltas seeing the most significant widespread subsidence are those on the Mekong, Nile, Chao Phraya, Ganga-Brahmaputra, and Mississippi rivers.
- As the world’s great deltas sink, humanity loses rich, irreplaceable agricultural lands, fisheries, urban areas and exceptional biodiversity — much of which will not be salvageable beyond a certain point. Delta loss poses a significant threat to global food security, and an existential threat to often impoverished delta communities.
- Delta subsidence can be slowed and even reversed by implementing well-understood mitigation strategies, say experts, by replacing hydropower dams with alternative energy, reducing sand mining and groundwater extraction, and altering agricultural practices. But these solutions are hampered by economics and lack of political will.

Study finds microplastics in tadpoles in the Amazon for the first time
Researchers have recorded microplastics in frog tadpoles and their pond habitats in the wild in the Amazon for the first time, according to a new study. This confirms widespread microplastic contamination in the Amazon Rainforest, the researchers say. Previous studies from the region have found microplastic contamination in fish, invertebrates, soil and water samples. […]
Saline intrusion in Mekong Delta leaves farmers and scientists at odds
- Vietnam’s Mekong Delta is increasingly facing saltwater intrusion, as sea levels rise, land subsides and the river’s natural cycles are disrupted by dams and irrigation infrastructure.
- A growing scientific consensus says Vietnam must learn to adapt to salt water rather than trying to engineer its way out of the problem; this perspective was officially integrated into Vietnam’s public policy with the 2017 Resolution 120.
- In practice, however, hard infrastructure like sluice gates are popular at the local level and continue to be built.
- Progress implementing Resolution 120 has also slowed due to 2025 administrative reforms that restructured ministries and re-drew provincial boundaries in the delta.

Bangladesh struggles to choose between food security & stable groundwater table
- With an aim to stabilize the groundwater table, Bangladesh declared 25 subdistricts of its northwestern part as water crisis zones in late 2025.
- Identifying irrigation as the major factor of the crisis, a government notice asked farmers to immediately halt the cultivation of high irrigation-fed boro paddy.
- Since the zone is also considered a rice-producing hub, the government later changed the direction for a limited time, considering the immediate impacts of hampering staple food production in the country.
- However, development professionals suggested shifts in agriculture practices from high irrigation-fed rice production to alternative crops to ensure a stabilized water table and livelihood for the people living in the region.

UN report flags disproportionate costs of clean energy transition
A new report published by the United Nations University Institute for Water, Environment and Health (UNU-INWEH) warns that wealthy nations’ push toward cleaner energy comes with high environmental and social costs in mineral-producing countries. The investigation links the extraction of transition minerals used in green energy technologies like solar panels and rechargeable batteries to acute […]
Nearly three in four marine protected areas undermined by wastewater pollution
- A global modeling study found that 73% of marine protected areas are exposed to nitrogen pollution from wastewater — often at higher levels than in nearby unprotected waters.
- The findings indicate that marine conservation planning often fails to adequately account for land-based wastewater pollution or to integrate land-sea management.
- Wastewater pollution, largely untreated globally, introduces nitrogen and phosphorous nutrients and other contaminants that degrade marine ecosystems, with impacts on coral reefs, seagrass and water quality, and can undermine the effectiveness of MPAs.
- Addressing the issue is considered feasible but constrained by fragmented governance, underfunding and limited monitoring, despite solutions that include existing technologies, various policy proposals and examples of improved wastewater management.

AI is a double-edged sword for Indigenous stewardship, say U.N. experts
- At the United Nations Permanent Forum on Indigenous Issues 25th session, U.N. experts called attention to the opportunities and dangers of AI-centered conservation efforts.
- A study published by former chair of the permanent forum Hindou Oumarou Ibrahim highlighted that AI can positively contribute to the protection of the environment but also impact efforts, due to its high consumption of energy, water and critical minerals.
- AI can support the protection and management of Indigenous peoples’ lands and resources, such as by monitoring the environment to detect deforestation, fires, or illegal extraction.
- Experts warned that to ensure the protection of Indigenous peoples and their territories, governments must prevent all forms of land-grabbing, water exploitation and mining activities related to data centers and energy sources, and respect Indigenous rights, worldviews and aspirations.

Malawi government suspends coal miner’s license over river pollution
- Northern Malawi hosts the country’s largest coalfields, providing energy to various industries, but some of the mines here have been associated with labor violations and environmental damage.
- In the latest case, a community in one of the key coal mining districts has demanded the closure of a mine for polluting two rivers from which locals draw water for domestic and agricultural use.
- Preliminary investigations by government agencies found evidence of contamination from the mine operated by Coal & Minerals Group Limited, but the company has denied deliberately discharging the waste into the rivers.
- Based on regulators’ findings, the company’s mining licensed has been suspended on the grounds that its operations “seriously threaten” the safety and health of the people and environment.

Asia’s longest free-flowing river contaminated by arsenic linked to Myanmar mines
- Independent testing of the Salween River began in September 2025 after researchers found alarming levels of toxic contaminants in the nearby Kok, Sai and Ruak rivers in Thailand, much of it linked to unregulated mining in Myanmar.
- Rare earth mines exporting crucial minerals needed for artificial intelligence, mobile phones, electric vehicles, renewable energy technologies and other uses have been blamed, but the mining of gold and various critical minerals also continues largely in secrecy across river basins in Myanmar.
- Most suspected mines were found upstream in the Salween’s basin, notably in Shan state, where various factions such as the United Wa State Army and the Myanmar National Democratic Alliance Army, as well as the Myanmar military, are fighting for territory.
- A working group was formed to address the growing issue of contamination across Thailand’s rivers, including the Salween, and tests showed arsenic levels at every monitoring point were more than double safety levels; news of the contamination has put local fishers and communities on alert.

In Tasmania, the mines have closed but the rivers remember
- Legacy copper mining in Tasmania, carried out for more than 100 years, has left parts of the King River ecosystem severely degraded, with scientists describing sections as “biologically dead” due to acid mine drainage and metal contamination.
- Globally, legacy mine waste has polluted hundreds of thousands of miles of rivers, exposing an estimated 23 million people to toxic metals, mostly through long-term sediment contamination rather than major disasters.
- Long-closed mines, which often operated with minimal or no environmental oversight, continue to leach waste from quarry and mine sites and tailings piles, causing long-term and ongoing contamination of rivers, streambeds and floodplains. Remediation across widely polluted landscapes is difficult and costly to carry out.
- Tasmania’s rivers are now a test case for the world: Despite decades of research and mitigation efforts, legacy pollution persists there, offering a warning as demand for critical minerals accelerates globally, with large amounts of copper and other metals required for electric vehicles, AI data center servers and other uses.

In Brazil, unfinished water project leaves Indigenous villages without safe water
- According to Brazil’s Ministry of Health data obtained by Mongabay, of the 4,134 Indigenous villages in Brazil’s North Region, only 1,934 — about 47% — have proper infrastructure to supply drinking water to the population.
- To avoid scarcity, many communities resort to improvised solutions, using buckets and pipes to fill their reservoirs with water from rivers and waterfalls. In times of drought, shallow wells are also dug on riverbanks.
- Their emergency strategy against thirst, however, increases a series of health risks, forcing entire villages to consume ferrous, dirty, and contaminated water — all vectors for infectious diseases.
- In some areas of the North, in addition to chemical purification solutions such as Salta-Z, nanotechnology-based collective filters have helped communities cope with the water crisis — and, according to their complaints, with government neglect.

Afghanistan’s capital is in the grip of a water crisis
KABUL, Afghanistan (AP) — Nestled in a high-altitude valley in Afghanistan’s Hindu Kush mountain range, Kabul is rapidly running out of water. Experts say climate change has played its part, but so has massive population growth and resource mismanagement. Many people, particularly in the poorer areas of the Afghan capital, are left struggling to cope. […]
Novel research finds unexpected climate resilience in up to 36% of Amazon forest
- In recent decades, the Amazon Rainforest has repeatedly and increasingly been struck by devastating drought along with record heat due to climate change. Add to this record wildfires, rapid deforestation and land conversion for agriculture.
- Numerous field studies and modeling have found that these extreme changes are pushing the Amazon toward a tipping point and collapse of the biome — an ecological disaster that would release large amounts of carbon into the atmosphere.
- But one research team, in a recently published study, offered up some hope: They found that little-studied low water table wetland Amazon forests — constituting up to 36% of Amazon trees — have stood up well to, and even thrived, during major droughts, with an increase in aboveground biomass.
- Those findings, the research team says, put the inevitability of an Amazon tipping point and collapse in some doubt, with the possibility that low water table forests could serve as a refugia for biodiversity. They also urge that these areas become a priority for protection and conservation as a hedge against future climate change.

AI infrastructure growth threatens water-stressed Thai regions
Thailand’s massive surge in data center development is prompting concerns about water shortages and pollution in already stressed regions. Mongabay’s Gerry Flynn reports that more than 70 data center-related projects are planned or underway, driven by global demand for AI and supported by government tax incentives. These projects are concentrated in the country’s Eastern Economic […]
A ‘big book’ documenting Cameroon’s sharks & rays fills critical conservation gap
- Between 2015 and 2023, researchers working with fishers recorded more than 7,000 sharks and rays caught at sea and landed along Cameroon’s coast.
- The recorded animals represent 45 species, of which 13 are critically endangered.
- Their research found that most sharks and rays landed in Cameroon’s fisheries are juveniles, raising serious concerns about population recovery.
- The data help scientists better understand species composition, catch trends and conservation priorities along Cameroon’s coast.

‘Sharing is off the table’ as drought reshapes the culture of Ethiopia’s pastoralists
- Pastoralists in Ethiopia’s Somali region say that worsening drought is eroding traditional systems of sharing that once helped communities survive.
- A recent study finds rainfall patterns have grown increasingly unpredictable, making it harder for pastoralists to plan and sustain their herds.
- Indigenous systems such as Gergar — a form of social insurance — and communal grazing are weakening as households struggle to sustain their own herds.
- As climate pressures grow, pastoralists are turning to alternative livelihoods, while assistance struggles to keep up with the scale of the problem.

Indonesia reviews firms in river basins after latest floods affect 7% of Bornean province
- The province of South Kalimantan experiences annual flooding, frequently worse than other Indonesian provinces on the island of Borneo.
- In late December, Indonesia’s environment minister said the government would review companies operating within watersheds in the province after a large share of the province’s 4.4 million people were impacted by floods at the end of last year.
- Civil society organizations and scientists say land-use change in the water catchment area has reduced the drainage capacity of soils and increased the likelihood of runoff, which inundates a large share of settlements in the province every year.
- A spokesperson for the environment ministry told Mongabay in March that a review of companies operating in the river basis was ongoing.

Local conservationists sustain research on threatened heron amid Myanmar instability
- Community-based surveys in northern Myanmar have documented a small population of white-bellied herons, one of the world’s most threatened bird species.
- Experts say the sightings reaffirm the conflict-torn area’s importance as one of the world’s few remaining strongholds for the critically endangered species.
- Several threats to the birds were identified, including opportunistic hunting using homemade guns, which the researchers plan to mitigate through outreach programs in local communities.
- The surveys were funded by a wider conservation program that aims to boost local capacity for conservation to cover diminished government support and reduced NGO presence amid Myanmar’s political crisis.

Study finds deforestation accounts for major Amazon rainfall decline
- A study looking at land and atmosphere interactions in the Amazon Basin across four decades found that 52-72% of the rainfall decline in the southern Amazon is due to large-scale deforestation.
- Between 1980 and 2019, annual precipitation in the southern Amazon declined by 8-11%, with most of the region losing on average 7.7% of its forest cover over largely the same period.
- The research also indicates that climate models might underestimate the contribution of deforestation to precipitation reduction by as much as 50%, which could mean that rainfall thresholds in the Amazon could be crossed earlier than expected.

A nature-based solution to save the Mekong Delta’s water future (commentary)
- The Mekong Delta — a global rice and aquaculture hub — is increasingly at risk from climate change, with rising seas, salinity intrusion, pollution and groundwater depletion threatening the livelihoods of dependant communities and lives of millions of residents in the delta.
- In Vietnam, a proposed nature-based groundwater replenishment system aims to combine water treatment, aquifer recharge and wind energy to boost clean water supply, reduce salinity and stabilize the delta’s fragile ecosystems.
- Backers say the plan could deliver hundreds of millions of dollars in annual benefits through higher farm yields, improved public health and stronger climate resilience, though it will require major investment and coordinated governance to succeed.

In Laos, ancestral spirits are helping save one of the world’s rarest crocodiles
- A decade-long conservation program built around local culture is restoring a globally significant population of a critically endangered crocodile species to the Xe Champhone wetlands of central Laos.
- Of the world’s 27 crocodilian species, the Siamese crocodile is among just four classified as critically endangered, with fewer than 1,000 thought to survive on Earth.
- This month, 56 crocodiles were released back to the Xe Champhone wetlands and the program has released 294 individuals since it began in 2013.
- The locals’ spiritual connection to crocodiles, upheld for generations in a landscape stripped of most large wildlife, may be the single most important reason this species still exists here.

Huge amounts of nanoplastics discovered in tap and bottled water
The amount of nanoplastics in drinking water in the U.S. has been wildly underestimated. That’s according to a new study that found the amount of plastic in both tap and bottled water was 10-100 times higher than previous estimates. For the new study, researchers used more advanced methodology and found more plastic. “It is like […]
World Water Day: Earth’s freshwater reveals new species & faces mounting threats
Water covers most of our planet, yet less than 3% of it is freshwater and most of it is contained in glaciers, making it not readily usable. Contamination and overuse threaten the valuable supplies of freshwater that humans and other animals, especially aquatic organisms, depend on to live. On World Water Day, a United Nations […]
Indonesia court orders release of withheld impact studies on new capital
- Indonesia mining industry watchdog Jatam has won a case at the country’s Supreme Court requiring the government to disclose environmental impact assessments pertaining to two utility water projects at the country’s new capital city site.
- In 2019, then-president Joko Widodo announced he would move the capital of the world’s fourth-most-populous country from Jakarta to Nusantara, a new site surrounded by forests and Indigenous communities on the east coast of Borneo.
- At issue are the Sepaku Semoi Dam and Sepaku River intake, two infrastructure projects at Nusantara that have impacted local Indigenous populations, Jatam said.
- The NGO called the ruling a victory for transparency, but criticized efforts to withhold documents and pointed to a 2008 law as well as Indonesia’s Constitution requiring public access to information.

Brazil is both the world’s environmental treasure and its most exposed victim (commentary)
- Brazil is one of the countries most exposed to climate breakdown and the one with the most power to slow it. Its failure to act on either front is becoming an economic and political emergency, argue Robert Muggah and Igor Oliveira of the Igarapé Institute.
- Brazil’s major biomes—the Amazon, Cerrado, and Pantanal—function as an interconnected system that regulates rainfall, water supplies, and agricultural productivity across the country. Degrading one part of that system destabilizes the others, creating cascading economic and environmental risks.
- Despite mounting evidence of climate vulnerability—from floods and droughts to energy and food price shocks—Brazil’s political and economic institutions have yet to integrate climate risk into national planning at the scale required, leaving the country increasingly exposed to systemic disruption.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

If Florida reefs aren’t protected, storms will increase flooding & costs: Study
- Coral reefs absorb incoming waves, protecting shorelines from tropical storms.
- A recent Earth’s Future study examines flood risks from tropical storms to communities in Florida, if coral reefs keep degrading at current rates.
- The study finds that future coral reef degradation will increase the annual risk of flooding to people by 42% and to buildings by 47%.
- This increased degradation would predictably cause $412.5 million in damages to structures and economic disruption of $438.1 million annually.

Thai data center boom sparks fears of water shortage, air pollution
- Thailand is experiencing a rapid data center boom, with more than 70 projects planned or underway, many clustered in the industrial Eastern Economic Corridor.
- Residents and farmers in Chonburi and Rayong provinces say they fear the facilities will intensify water shortages and pollution in a region already struggling with industrial impacts.
- Data centers require large volumes of water for cooling and major electricity supply, raising concerns about wastewater contamination and increased burning of fossil fuels.
- Critics say the sector is expanding with little transparency or community consultation, leaving locals uncertain about environmental safeguards and benefits.

Beyond the Potomac River, sewage spills threaten cities with old infrastructure and little funds
WASHINGTON (AP) — A major sewer pipe collapse has dumped hundreds of millions of gallons of sewage into the Potomac River, highlighting a nationwide problem involving failing infrastructure. The Potomac spill was a huge, but rare event that led to an emergency declaration and federal help. But across the country, sewer overflows happen tens of […]
Mining rush for critical minerals threatens Amazon land reform settlements
- A survey of mining records found dozens of requests for copper, manganese and nickel targeting land reform settlements in northern Brazil’s Carajás region in the last five years.
- The rush for critical minerals is creating potential “sacrifice zones” of contaminated waterways and declining fish populations in the Amazonian settlements.
- These minerals are vital for cars, batteries and war industries, linking increasing global demand to local Amazon conflicts and poverty, despite a local tax boost.

25 years after ‘disaster’ declaration, major U.S. fishery makes a comeback
- In 2000, the U.S. commerce secretary declared the groundfish fishery on the U.S. West Coast a “disaster,” with 10 key species overfished to below a quarter of their healthy levels.
- Fisheries authorities empowered by federal conservation laws took drastic action: They cut off vast tracts of the ocean to trawling, slashed fishing quotas and bought fishing vessels to remove them from operation. Many fishers were thrown into painful retirement.
- Careful management and innovation in the intervening years has led to a remarkable turnaround: In October 2025, fishery officials declared the last of the 10 overfished species to be rebuilt, years earlier than expected, and fishers have catches they thought would never be possible again.
- Even so, fishers’ profits have been low, and experts worry that key conservation programs could lose their teeth to cost-cutting measures and deregulation.

Falling Amazon river flows trigger reality check at Belo Monte power plant
- Studies warn that climate change could slash hydropower generation across the Amazon by up to 40%, with controversial Belo Monte among the most exposed plants in Brazil.
- Researchers and regulators say relying on historical river flows is no longer viable as droughts intensify and rainfall patterns drop.
- Belo Monte’s operator argues the plant remains strategic for Brazil’s energy security, despite growing climate risks.

Petrostates stymie effort to rein in Arctic shipping carbon emissions
- Black carbon emissions (colloquially known as soot) produced by marine shipping contribute to Earth’s warming climate and also reduce ice and snow cover. In the Arctic, those emissions are hastening regional heating and sea ice loss.
- In the 21st century, climate change has so diminished Arctic sea ice thickness and extent that transpolar crossings in summer by large numbers of commercial vessels has not only become possible but also increasingly frequent, resulting in a marked increase in black carbon emissions from dirty fossil fuels.
- In February, members of the International Maritime Organization (IMO) considered a proposal by several nations to require use of cleaner polar fuels, which emit lower amounts of black carbon. But the effort was blocked and delayed by large petrostates, including the U.S., Russia and Saudi Arabia.
- Implementation of the measure is expected to be delayed by at least two years. With Arctic sea voyages forecast to soar from thousands of trips annually to tens of thousands by 2050, NGOs are calling for greater support for clean polar fuels as a quick and effective way of reducing warming pressure on the Arctic region.

The Amazon’s most valuable export isn’t timber — it’s rain
- Tropical forests actively generate rainfall by releasing moisture into the atmosphere, with each square meter producing hundreds of liters of rain annually across surrounding regions. Clearing even small portions can measurably reduce precipitation, especially during dry seasons.
- Much of the rain that falls far inland originates from forests through long-distance moisture transport known as “flying rivers,” meaning farms, cities, and reservoirs may depend on ecosystems located hundreds or thousands of kilometers away.
- Reduced rainfall from deforestation can undermine agriculture, river flows, and hydropower, revealing forests as a form of natural water infrastructure that supports food production, energy systems, and economic stability.
- By assigning a monetary value to forest-generated rainfall, researchers estimate the service in the Amazon alone is worth on the order of tens of billions of dollars annually, underscoring that forest loss threatens not only biodiversity and carbon storage but regional climate systems themselves.

Seven years after Brazil’s worst dam disaster, mining operations bounce back
- Seven years after a dam holding mining sludge collapsed in Brumadinho, southeastern Brazil, killing 272 people, mining giant Vale and its partner Itaminas are resuming operations at the very same mining complex.
- The reopening of the Jangada mining site threatens the local community’s water security by potentially lowering the water table and compromising springs that supply hundreds of families in Brumadinho’s rural area, residents say.
- Residents, victims’ relatives and civil society organizations have flagged the lack of information about the environmental risks that persist in a territory scarred by one of the worst mining-related disasters in Brazil.

Forests don’t just store carbon. They keep people alive, scientists say
- Forests influence climate not only by storing carbon but by cooling the air, moderating extreme temperatures, and regulating water flows in ways that directly affect human well-being, concludes an academic review published this week in the journal Science.
- These effects are strongest at the local level: intact forests can make surrounding areas markedly cooler, stabilize rainfall, and create microclimates that support agriculture, health, and daily life.
- When forests are cleared, those protections can disappear quickly, often producing hotter, drier conditions and exposing large populations to increased heat stress and associated health risks.
- The greatest climate benefits occur where forests are native, underscoring that protecting and restoring natural ecosystems can be as important for adaptation to climate change as for reducing emissions, argues the paper.

Farmers fear displacement, drought, flooding tied to Cambodia’s Funan Techo Canal
- The Cambodian government is set to begin construction of the Funan Techo Canal, a nearly $1.2 billion, 180-kilometer (112-mile) waterway navigation project that will cut across four provinces to connect the Mekong River to the sea.
- The primary rationale for building the canal is to reduce Cambodia’s shipping costs, as well as to generate jobs and economic development.
- Mongabay has followed this mega-project’s development for more than a year, speaking with more than 50 people living along the canal’s proposed route. Virtually everyone we spoke with noted that the government has provided very little information about the project, and amid the uncertainty, fear has taken root.
- In inland communities in the rich floodplains of the Mekong River, farmers we spoke with said they worried they’d lose their homes or land, and that construction would disrupt the annual months-long inundation of the wetlands they rely on for planting rice as well as for fishing, crabbing and raising livestock.

Mapping underground fungal networks: Interview with SPUN’s Toby Kiers
- Mycorrhizal fungi are found in every soil system on Earth, and have symbiotic relationships with the plants whose roots they live on.
- They receive carbon dioxide from plants in exchange for nutrients, making them major carbon repositories and an important tool for carbon sequestration.
- The Society for the Protection of Underground Networks (SPUN) is deploying a wide range of technologies, from remote sensing to imaging robots, to map these crucial underground networks.
- “We think of these networks as one of Earth’s circulatory systems, but people are not paying attention,” SPUN co-founder Toby Kiers tells Mongabay in an interview.

Kathy Jefferson Bancroft, guardian of a stolen lake
- For decades, Kathy Jefferson Bancroft challenged the idea that Owens Lake was merely a technical problem, insisting it be understood as a living place with history, meaning, and obligations.
- As Tribal Historic Preservation Officer for the Lone Pine Paiute–Shoshone Tribe, she worked at the intersection of Indigenous knowledge and Western science, pressing agencies to account for longer timescales and deeper responsibilities.
- Her advocacy helped protect sacred sites, resist destructive mining and mitigation schemes, and reshape how land and water decisions were made in California’s Owens Valley.
- Bancroft’s work rested on a simple proposition that unsettled bureaucracies: water is not something to be managed at will, but something that carries memory, limits, and consequence.

Ethiopia’s Renaissance mega-dam fuels energy hopes and regional anxiety
- Ethiopia inaugurated Africa’s largest hydroelectric dam in 2025, positioning itself as a regional energy exporter while millions of its citizens still lack access to electricity.
- Egypt, which lies downstream in the Nile Basin, views the Grand Ethiopian Renaissance Dam as an existential threat, warning of risks to Nile water security and regional stability.
- Scientists caution that dam failures or mismanagement could trigger catastrophic flooding in Sudan and Egypt.
- Critics argue that the dam may serve as a geopolitical and public relations tool, while its environmental and social impacts remain insufficiently assessed.

When nature becomes a security risk
Britain’s national security thinking has traditionally been shaped by familiar concerns: hostile states, terrorism, energy supply, and, more recently, cyber threats. A new assessment from the U.K. government adds a different category to that list. Global biodiversity loss and ecosystem collapse, it argues, now pose a direct and growing risk to national security, with implications […]
A ‘new baseline’: Study captures accelerating sea-level rise in Africa
- Sea-level rise has accelerated across Africa in recent decades, thanks to global warming and, in particular, to the melting of ice sheets and glaciers, according to a recent study.
- Sea levels across the continent have risen four times faster since 2010, on average, than they had in the 1990s. About 80% of the sea-level rise is due to added water mass from meltwater.
- The impacts include flooding, erosion of coastal land, intrusion of salty seawater into freshwater drinking sources and displacement of coastal communities.
- In many coastal areas, sea-level rise occurs even as the land itself is sinking due to groundwater extraction or other factors, exacerbating its impacts.

Critical wetland in Angola gets formal Ramsar recognition
In a remote part of Angola’s highlands, a critical natural reservoir or “water tower” has been recognized as a wetland of international importance. Known to locals as lisima lya mwono, or “source of life,” the area supplies water to the region’s most important rivers and supports unique native wildlife. Officially designated last October by the […]
IUCN launches group to conserve at-risk microbes vital to life on Earth
- Microbial communities, though invisible to the naked eye, are vitally important to planetary health and to Earth’s ecosystems. But they are often neglected in conservation strategies.
- Like other branches of life, microbial communities are under threat due to climate change, pollution, land use change and a wide range of other human actions. Degraded microbial communities can have harmful consequences for human well-being, ecosystems health and wider planetary processes.
- A newly launched specialist group under the International Union for the Conservation of Nature (IUCN) aims to place microbes on the conservation agenda.
- The new IUCN group plans to develop conservation strategies aimed at identifying and protecting at-risk microbial species vital to planetary health and create a Red and Green List, similar to those that exist for threatened animals and plants.

What can—and cannot—be done to save the world’s glaciers
- Glaciers function as critical infrastructure, supplying water, food, and energy for nearly half the world’s population, even though they cover only a small share of the Earth’s surface. That support system is now contracting rapidly.
- Global measurements show sustained and accelerating glacier loss since the 1970s, driven primarily by human-caused warming. In many regions, what was once seasonal melt has become irreversible decline.
- The impacts extend well beyond the mountains, affecting agriculture, hydropower, ecosystems, and disaster risk in downstream communities across Asia, South America, and beyond.
- While scientists and policymakers are testing ways to manage shrinking ice and rising hazards, adaptation has limits. Without deep cuts in greenhouse-gas emissions, many glacier-fed regions will soon face long-term water decline.

Photos: Top new species from 2025
- Scientists described several new species this past year, including a tiny marsupial, a Himalayan bat, an ancient tree, a giant manta ray, a bright blue butterfly and a fairy lantern, to name a few.
- Experts estimate that fewer than 20% of Earth’s species have been documented by Western science, with potentially millions more unknown and unnamed.
- Although such species may be new to science, many are already known to — and used by — local and Indigenous peoples, who often have given them traditional names.
- Many new species are assessed as threatened with extinction as soon as they are found, highlighting the urgent need for conservation efforts.

On Indonesia’s longest river, a Borneo community passes crucial public health milestone
- Sekadau is the largest settlement in a district of the same name on Indonesia’s longest river, the Kapuas River in Borneo.
- Historically, Sekadau has recorded higher rates of acute illness that local authorities suggested may be attributable to the widespread practice of open defecation in the river, a public health menace that exacts a range of costs from economic productivity to child stunting.
- This year, the district of Sekadau announced it had eliminated open defecation from all 94 villages in the district of 211,559 people, thanks in part to a campaign to build affordable toilets.
- Data collected by local authorities showed instances of ill health have declined swiftly over the last decade.

Project sees long-term success restoring forests in the high Andes: Study
- The Polylepis forests of Peru are some of the highest high-altitude forests in the world, playing an essential role in the water cycle.
- Over the past few decades, various restoration projects have worked to restore Polylepis forests across their former range.
- In 2022, researchers revisited a restoration project in Aquia, Peru, to understand what factors contributed to its success. The study concludes that stakeholder participation and formal conservation agreements helped the project succeed.
- Over the past four years, initiatives by ECOAN and Accion Andina have built on previous success.

Ethiopian youth groups restore Rift valley lake & livelihoods
- Youth groups are restoring the ecosystem in and around Ethiopia’s Abijata-Shalla National Park, once covered with acacia woodlands but stripped bare in recent years as water has been lost to irrigation and a soda-ash factory.
- Spanning 887 square kilometers, the park is a vital refuge for biodiversity, hosting migratory birds and a range of species, making it one of the region’s most important wildlife strongholds.
- Wetlands International staff have trained local youth and community members in sustainable land management, teaching them how to identify and correct unsustainable practices such as overgrazing, deforestation and farming on steep slopes.
- The work relies heavily on consultations with local communities, ensuring solutions align with community needs.

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.

West and Central Africa tackle coastal erosion
- Coastal erosion along the coastline of West and Central Africa has been attributed to both natural causes and to human causes, including infrastructure development.
- With support from international finance agencies, governments cross the region have favored intensive engineering solutions to attempt to protect eroding shorelines.
- Environmentalists say nature-based interventions such as restoring mangrove forests that can stabilize soil and protect marine biodiversity.

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.

Can two Amazons survive? Invisible e-waste is poisoning the world
- E-waste, which refers to discarded electrical or electronic devices, is the fastest growing domestic waste stream in the world, and it is highly toxic, threatening public health. Much of this e-waste, largely produced by rich countries, is dumped in poor countries, with Asia and Africa major destinations.
- Because poor countries mostly lack the highly sophisticated equipment and processes needed to dismantle and recycle these complex composite products safely, unskilled scrap workers, including children, plunder them for resalable components, often with a disastrous impact on their health and the environment.
- Increasingly, the torrent of discarded cell phones and obsolete computers is greatly exacerbated by invisible e-waste: a vast, varied plethora of microchip-containing products, ranging from vaping devices to e-readers, toys, smoke detectors, e-tire pressure gauges and chip-containing shoes and apparel.
- Invisible e-waste greatly adds to developing world recycling challenges. The U.N. Environment Programme warns that “the increasing proliferation of technological devices has skyrocketed the amount of electronic waste worldwide” with nations now facing “an environmental challenge of enormous dimensions.”

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.

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.

Indian megacities are sinking putting thousands of buildings at risk: Study
Parts of Delhi, Mumbai, Chennai, Kolkata and Bengaluru, India’s largest cities, are slowly sinking, mainly due to overextraction of groundwater, according to a recent study, reports Mongabay India’s Manish Chandra Mishra. Researchers used eight years of satellite radar data and found that 878 square kilometers (339 square miles) of land across the five megacities show […]
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.

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.
- Documents show that a company linked to tycoon Try Pheap controlled the mining area at the time when communities reported pollution that’s left them fearful for their health, livelihoods and food security.

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.

IDB financed meat & poultry company that polluted Indigenous Ecuador lands: Report
- A report from the Independent Consultation and Investigation Mechanism of the Inter-American Development Bank (IDB) Group says that agribusiness Pronaca contaminated for decades the Tsáchila Indigenous Territory in Ecuador.
- IDB Invest financed Pronaca, a major player in meat and poultry products, without adequately evaluating the company’s environmental and social impacts, according to its own conclusions.
- According to the report, for years, the company discharged residual waters from pig farms into the rivers that the Tsáchila depend on, affecting their health, culture, farming and tourism.
- Inés Manzano, Ecuador’s Minister for Environment and Energy, is married to Christian Bakker, who is part of the family who founded Pronaca.

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.

Plans to dispose of mining waste in Norway’s Arctic Ocean worries Sámi fishers, herders
- Mining company Blue Moon Metals plans to dispose of its mining waste in Repparfjord, a nationally protected salmon fjord in the Norwegian Arctic that Indigenous Sámi fishers rely on.
- When operational, the Nussir ASA copper mine will deposit between 1 million and 2 million metric tons of tailings at the bottom of the fjord annually, according to the company’s permit.
- The Norwegian Environment Agency told Mongabay that the company plans to place its mining waste into the fjord in a controlled manner to limit the dispersal of harmful residues.
- Some Sámi residents, whose livelihoods depend on fishing and reindeer herding, told Mongabay they fear the tailings and mine will destroy vital marine habitats for salmon and disrupt traditional reindeer breeding and migration areas.

AI data center revolution sucks up world’s energy, water, materials
- Data centers are springing up across tropical Latin America, Southeast Asia, Indonesia and Africa. But these facilities are often unlike those of the recent past. Today’s advanced data centers are built to provide artificial intelligence (AI) computing capacity by Big Tech companies such as Microsoft, Google and Amazon.
- As large AI data centers proliferate, they are competing for water, energy and materials with already stressed tropical communities. National governments frequently welcome Big Tech and AI, offering tax breaks and other incentives to build AI complexes, while often not taking community needs into consideration.
- Aware that fossil fuels and renewables by themselves likely can’t handle the astronomical energy demands posed by AI mega-data centers, Internet companies are reactivating the once moribund nuclear industry, despite intractable problems with radioactive waste disposal.
- Voices in the Global South say that AI computing (whose producers remain principally in the Global North) is evolving as a new form of extractive colonialism. Some Indigenous people say it is time to question limitless technological innovation with its heavy environmental and social costs.

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.

Study finds deforestation fuels West Africa’s water crisis
A new study warns that deforestation across Ghana, Niger and Nigeria is intensifying West Africa’s water crisis, threatening the health and livelihoods of more than 122 million people. Drawing on 12 years of satellite data from 2013-2025, the joint report by WaterAid and Tree Aid finds a direct correlation between forest loss and the decline […]
Report identifies 10 emerging tech solutions to enhance planetary health
- A recent report underlines 10 emerging technologies offering potential to accelerate climate action, restore ecosystems, and drive sustainable innovation within safe planetary boundaries. These technologies include AI-supported Earth observation, automated food waste upcycling, green concrete and more.
- Innovative AI improvements in Earth observations (EO) can better identify and track human-caused environmental impacts and offer improved early warning alerts for planetary boundary overshoot. Such systems use AI-powered analytics to synthesize satellite, drone and ground-based data for near-real-time results.
- Artificial intelligence and automation can also work in tandem to manage citywide food waste programs, ensuring that food scraps are diverted from landfills or incineration, decreasing carbon emissions and reducing waste.
- Another tech solution is green concrete which could not only reduce emissions from traditional cement production, but when incorporated into infrastructure construction, can offer a permanent storage place for captured CO2.

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 […]
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.

Lithium mining may threaten a precious resource — water: Voices from the land (commentary)
- Large-scale lithium mining may impact scarce and precious water resources and balance in Argentina’s arid ecosystems, says Clemente Flores, president of the El Angosto Indigenous community.
- Flores says Indigenous communities manage water communally and this regulates how much they can grow, how many animals they can have, and it shapes their way of life and customs.
- Companies are mining “to save the world from the impacts of climate change by using the minerals for renewable technologies,” he says in this opinion piece. “But we want to be included among those who will be saved — not sacrificed to save others.”
- This commentary is part of the Voices from the Land series, a compilation of Indigenous-led opinion pieces. The views expressed are those of the authors, not necessarily Mongabay.

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.

How to clean solar panels in arid areas? Waterless systems could improve efficiency
- A recent report details a waterless solar cleaning system design developed to address the challenge of dust accumulation on solar panels in arid regions; it is one of multiple waterless cleaning systems that have come about in recent years.
- The study reported a significant 26.2% average increase in power output and reduced losses due to dust accumulation.
- The development of this waterless system design has the potential to unlock new opportunities for energy access and economic development in sub-Saharan Africa, although cost and availability questions remain.
- Waterless solar panel cleaning systems could be particularly beneficial in arid regions where water scarcity is a significant issue; this technology can help to support sustainable development and reduce the strain on local water supplies.

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.

Guava yields in South Asia shrink due to unpredictable heat & rainfall
- Changing rainfall patterns due to climate change are posing threats to guava farming in South Asia, the global hub of the tropical fruit.
- In recent years, rising temperatures and delayed monsoons have been affecting the flowering and fruiting of even the drought-tolerant guava varieties.
- Experts in India, Pakistan and Bangladesh have identified links to climate change with vulnerabilities in guava farming and suggest solutions.

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.

‘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.

Local divers pick away at Lake Malawi’s underwater garbage problem
- Accumulations of trash lie below the tranquil waters of Lake Malawi National Park, a problem local environmentalists say likely extends throughout Lake Malawi, the world’s fourth-largest freshwater lake by volume.
- They blame dumping by lake users as well as poor waste handling upland within Malawi and in Mozambique and Tanzania, which share the lake’s shoreline. Malawi does not have public waste recycling facilities and all municipalities dump waste in open landfills where it risks draining into river systems.
- Divers with a local nonprofit volunteer collecting lake garbage in return for training and the use of diving equipment to make a living guiding tourists.
- Meanwhile, the Malawian government is working with universities to map and eventually clean up garbage hotspots in the lake as it works to strengthen waste management in the country.

Copper rush pushes Vale to ramp up mining near Amazonian protected areas
- Mining giant Vale has obtained a preliminary license for its Bacaba project, the first step toward doubling its copper production in the Brazilian Amazon over the next decade.
- Experts warn the expansion, near several conservation areas, will worsen deforestation, increase water stress and raise the risk of pollution.
- The global demand for copper is expected to rise by more than 40% by 2040, and almost all of Brazil’s known reserves are in the Amazon.

Uphill battle to save California’s endangered mountain yellow-legged frog
- Conservation organizations released 350 mountain yellow-legged frogs earlier this year, marking another step in an intensive, long-running reintroduction project for this highly endangered species in Southern California.
- Once abundant across its range, populations have declined drastically because of invasive fish species, climate change impacts, and the deadly chytrid fungus that is wiping out amphibians worldwide.
- Conservationists are testing out new ways to boost survival rates of released frogs. Though it’s hoped the species may one day recover, today they are locked in a fight against extinction.

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.

Women in Mexico step up to protect the island farms traditionally inherited by men
- In Mexico, traditionally women did not inherit chinampas, island farms first built by the Aztecs thousands of years ago. The farming on such islands, which sit in Mexico City, has also traditionally been done by men.
- Today, women are buying up chinampas and doing sustainable farming, along the way helping to maintain ecosystems that are threatened by urbanization and water pollution.
- This wetland system is the last remnant of what was once the great Tenochtitlan, the capital of the Aztec Empire built on the lakes that once filled the Valley of Mexico.
- What remains of Xochimilco today represents only 3% of the original extension of those lakes. However, the chinampas are still key to the stability of the city.

Africa’s largest freshwater lake could be site of Kenya’s nuclear power plant
- The proposal to build a 1,000-MW nuclear power plant on Kenya’s southeastern coast has faced strong opposition from residents and environmental experts, who warn of potential harm to communities, fisheries and the environment.
- Government agencies are now holding consultations at another prospective location on the other side of the country, near Lake Victoria, Africa’s largest freshwater lake.
- Kenya’s energy needs today are met mostly from low-carbon sources, and the country is on track to achieve universal energy access by 2030, but authorities say nuclear power is needed to meet future development goals.
- Some experts, however, warn about the high costs, delays, and long-term environmental risks associated with nuclear power projects.

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.

There’s far less land available for reforestation than we think, study finds
- In recent years, policymakers have made pledges for huge tree-planting projects a cornerstone for meeting national carbon reduction goals, while doing little to seriously cut fossil fuel emissions. But a new study shows the carbon sequestration estimates made for those forestation projects may be wildly optimistic.
- The new research determined that land found suitable for forestation in past studies — an area about the size of India — shrank by as much as two-thirds when adverse impacts on biodiversity, food security and water resources were taken into account.
- When the new study figured in environmental and social constraints, the potential for existing tree-planting pledges to store a promised 40 gigatons of carbon by 2050, was reduced to just 12.5 gigatons — a significant sum, but far from what’s needed to offset continued fossil fuel use.
- The new study urges policymakers to be more pragmatic in their planting strategies, and prioritize lands best slated for permanent reforestation. Other researchers urge decision-makers to put more effort and money into protecting already existing biodiverse forests, which hold high carbon storage potential.

The fate of flying rivers could decide Amazon ‘tipping point,’ report says
- The Amazon’s “tipping point” refers to the transition of the rainforest into a drier, savanna ecosystem. The rainforest’s ecological balance depends on the transport and recycling of moisture, but deforestation has been shown to disrupt the region’s water cycle.
- Moisture moves east to west, from the Atlantic Ocean across the Amazon Basin via what scientists call “aerial” or “flying rivers,” a critical mechanism in the region’s water cycle.
- A new report from Amazon Conservation’s Monitoring of the Andes Amazon Project identified areas of deforestation that disrupt these flying rivers from hundreds of miles away. It also found that not all parts of the Amazon have the same tipping point.
- The researchers stressed the need for regional, transboundary conservation efforts that account for varied threats in different parts of the Amazon.

Scientists weigh giant sea curtain to shield ‘Doomsday Glacier’ from melting
- Scientists have proposed using anchored seabed curtains to block warm ocean water from accelerating ice loss at Antarctica’s rapidly melting Thwaites Glacier — a possible climate fix that falls into the realm of geoengineering.
- Thwaites is losing 50 billion metric tons of ice annually and could raise sea levels by more than 60 cm (2 ft) if it collapses.
- Critics warn that a handful of proposed geoengineering projects in the world’s polar regions distract from decarbonization efforts, while supporters argue some geoengineering may be a necessary last-resort measure as governments fail to address rising greenhouse gas emissions.
- The curtain project could cost up to $80 billion, scientists estimate, but may prevent trillions in climate-related damages.

What Republic of Congo’s gold rush is leaving behind
DIMONIKA BIOSPHERE RESERVE, Republic of Congo — Gold mining by the Chinese company City SARL inside the Dimonika Biosphere Reserve in the Republic of Congo has devastated 5 hectares (12 acres) of forest. Artisanal gold miners and some local community members have had to leave the area, depriving them of food and drinking water. Water […]
Indonesia’s giant Java seawall plan sparks criticism & calls for alternatives
- Indonesia has launched a massive new project on Java’s northern coast, framed as protection for millions of residents from worsening environmental threats.
- The plan has drawn sharp criticism from experts and activists who question its methods, costs and potential impact on vulnerable communities.
- Calls are growing for deeper public consultation and long-term solutions that go beyond quick fixes.

In Argentina, lithium exploration proceeds amid community disputes
- In 2023, the Argentine crude oil exporter Pan American Energy announced its plans to start exploring for lithium in Argentina’s Jujuy and Salta provinces.
- Sources told Mongabay that the company did not conduct an adequate free, prior and informed consultation (FPIC) with affected communities before beginning to explore for lithium on their ancestral land.
- They also expressed concerns about the lack of public information about the mining projects and the potential impact on the Salinas Grandes and Laguna de Guayatayoc basin, which Indigenous communities in the region depend on for their livelihoods.
- Lithium mining here may impact two important flamingo species that inhabit the region and other key wetland bird species, biologists have said.

Lithium mining leaves severe impacts in Chile, but new methods exist: Report
- A new report on the impact of lithium mining in South America’s lithium triangle finds the rush to extract lithium in Chile’s Salar de Atacama has had a severe impact on the area’s water supplies.
- This has impacted the region’s Indigenous peoples, including the Lickanantay (Atacameño) peoples, who have faced a loss of vegetation cover and the disappearance of lagoons they depend on.
- Indigenous Colla people, whose land has not yet been exploited, told Mongabay they are concerned about the potential impact on their water supply if mining proceeds without implementing more sustainable mining methods, such as direct lithium extraction (DLE) technologies.
- Researchers say DLE can reduce the amount of water needed for lithium mining but it still comes with challenges.

Cambodian irrigation dam construction threatens riverine communities in the Cardamoms
- Cambodia has begun clearing more than 7,300 hectares (18,000 acres) of protected rainforest in Kravanh National Park to build an irrigation dam, with nearly 4,000 hectares (10,000 acres) to be submerged by its reservoir.
- The Cardamom Mountains, where the park is located, are among Cambodia’s last biodiversity hotspots, home to elephants, pangolins and gibbons, but dam projects and illegal logging are accelerating habitat loss.
- Villagers upstream of the dam say they’ll lose forest access, water and livelihoods, while downstream rice farmers stand to benefit; residents report they were not properly consulted.
- The project overlaps with a REDD+ carbon-offset area and appears to have broken ground without a completed environmental impact assessment, raising legal and transparency questions.

Post-Blob, California’s kelp crisis isn’t going away
- Kelp forests function as major habitat for marine biodiversity, but are in rapid decline worldwide, largely because of climate impacts on the oceans.
- A 2013 marine heat wave known as “the Blob,” combined with the mass die-off of sea stars, caused a 95% loss of Northern California’s kelp forests.
- The loss of sea stars allowed the purple urchins that they thrive on to spread rapidly, converting lush kelp forests into “urchin barrens” in parts of California. There’s been very little recovery since.
- Restoration of kelp forests is extremely difficult and requires far more resources than are currently being committed.

New study pinpoints tree-planting hotspots for climate and biodiversity gains
- Reforestation is gaining global momentum as a climate solution, but its success depends on how and where it’s done.
- A new study mapped locations where tree planting and forest regrowth are most likely to deliver climate, biodiversity and community benefits, while avoiding negative trade-offs. It identified 195 million hectares (482 million acres) of reforestation hotspots, a figure significantly smaller than previous estimates.
- Previous studies have been criticized for including grasslands and drylands, where planting trees may harm biodiversity and compromise ecosystem services. Some experts, however, argue that restrictive approaches risk excluding important ecosystems from restoration agendas.
- Scientists caution that tree planting alone won’t solve climate change, and that protecting existing forests while cutting emissions would provide greater climate benefits.

Discovery of dazzling blue butterfly underscores peril facing Angola’s forests
- Scientists have described a new butterfly species, Francis’s gorgeous sapphire (Iolaus francisi), from Angola’s Namba Mountains, where its survival depends on mistletoe plants.
- High-altitude evergreen forests, known as Afromontane and covering about 590 hectares (1,460 acres) in the Namba Mountains, are the largest of their kind in Angola but remain without legal protection.
- Researchers warn that fires, timber harvesting, and especially unregulated farming could devastate the forests, as has happened at Kumbira, another Angolan Afromontane forest.
- Conservationists say community-led initiatives are key to protecting Namba, as Angola’s parliament moves to consider protected status for nearby Mount Moco, another Afromontane oasis.

An Indigenous-led solar canoe initiative expands across the Amazon
- Eight years since its launch, a solar-powered canoe initiative by the Kara Solar Foundation in Ecuador has expanded to Indigenous coastal communities in Brazil, Peru, Suriname and the Solomon Islands.
- Kara Solar representatives and Indigenous leaders say the project leads to a decrease in gasoline and diesel use that pollute waterways, reduces the need for road expansion and helps communities develop non-extractive income projects.
- By 2030, they hope to expand and support the operation of 10,000 solar-powered boats across the Amazon Basin and build a network of Indigenous-owned and operated recharge stations.
- But access to the required large amount of financing or investment remains a challenge and the project is exploring funding models for communities.

In Nepal, artificial ponds offer drought relief despite lingering doubts
- As Nepal’s plains face severe drought, communities are building artificial ponds to cope with water shortages for drinking, irrigation and other uses.
- The ponds are becoming popular as a “nature-based solution” with both local communities and the government supporting their construction.
- Scientific studies and anecdotal evidence suggest that these ponds are successful in raising groundwater levels as well as reducing negative human-wildlife interactions.
- However, experts warn of significant gaps in knowledge, noting that many ponds are poorly designed, unscientifically built or located in unsuitable areas.

Ocean-based carbon storage ramps up, bringing investment and concern
- Storing captured carbon in the subsea — in depleted oil and gas wells or in aquifers — is ramping up as a climate solution, with projects planned across the globe by industry and governments.
- Tipped as a way to address “hard-to-abate” emissions from industries such as cement, steelmaking and chemicals, it’s hailed by proponents as a viable and necessary part of the transition to net-zero greenhouse gas emissions.
- But critics say offshore CCS poses great risks and will perpetuate a history of failure that has plagued onshore efforts to store carbon.
- It also raises environmental concerns, such as the potential for carbon leakage that could undermine climate efforts and harm marine life, contributing to already increasing ocean acidification.

As fast-spreading mussel sweeps across Asia, Sri Lanka faces new invasive threat
- The black mussel (Mytella strigata), a fast-spreading mollusk of South American origin was recently discovered in shrimp farms along Sri Lanka’s western coast, closer to Anawilundawa, an important Ramsar wetland in the Indian Ocean island.
- Native to Pacific and Atlantic coasts from Mexico to Argentina, this mussel has turned invasive in the U.S., Southeast Asia and India’s Kerala backwaters, thriving in a wide range of salinities and temperatures.
- In invaded regions, dense colonies foul aquaculture gear, reduce oyster spat settlement, and outcompete native bivalves, threatening both biodiversity and livelihoods.
- Alongside M. strigata, invasive mollusks like the giant African land snail and apple snails are already established, underscoring the need for stricter biosecurity, early detection and rapid response.

How will fisheries change in a hotter world? Experts share
- Fifty years from now, in 2075, global ocean temperatures are forecast to rise by between 2° and 5° Celsius (3.6° and 9° Fahrenheit). Warming is already reshaping fisheries worldwide, and even more dramatic changes are expected as fish largely move to cooler latitudes.
- These fish migrations will change ecosystem patterns and will likely have unexpected consequences even in places far from the fish themselves. They also may devastate fishing communities, both on an economic scale and a social one.
- However, there are potential solutions to avoid the most catastrophic effects for fishers and ecosystems alike, including setting aside some ecosystems as marine protected areas, changing fisheries management strategies and retraining communities to provide supplemental income.

Global wetlands conference results in resolutions for protection & restoration
- In July, scientists, government officials and community leaders gathered in Zimbabwe for the 2025 international conference on wetlands to agree on global commitments for the sustainable conservation and restoration of these ecosystems.
- The conference adopted a series of resolutions and agreements, including one on the protection of migratory birds and wetland-dependent species, as well as the Fifth Strategic Plan, which aims to halt and reverse wetland loss by 2034.
- The strategic plan highlighted the importance of including youth, Indigenous peoples, women and local communities in successful wetland conservation efforts.
- Conserving and restoring 550 million hectares (roughly 1.3 billion acres) of wetlands is essential to meeting global biodiversity and climate targets, according to the Global Wetland Outlook, but funding for wetland conservation remains low, accounting for only 0.25% of global GDP.

Restoration brings back fresh water, wildlife to degraded páramos in Ecuador
- Ecuador’s Antisana páramo, southeast of Quito, was degraded for centuries by cattle ranches.
- In 2010, the Quito Water Conservation Fund and the Quito’s water utility secured funding to buy one of the most heavily impacted properties.
- The Quito Water Conservation Fund, funded by contributions from drinking water users, is a sustainable initiative that protects vital water sources.
- Once non-native livestock were removed and restoration began, native vegetation, wetlands and species like deer, rabbits and foxes returned.

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 […]
Nepal’s hydropower developers watch closely as court nears key verdict
- Nepal’s private hydropower developers await the full text of a Supreme Court verdict that will decide the fate of infrastructure, such as dams and transmission lines, inside the nation’s natural protected areas.
- The court’s initial summary order, issued in January, scrapped a 2024 law that had permitted such projects. It found the law unconstitutional, citing violations of the right to a clean environment and principles of intergenerational equity.
- Hydropower producers, who contribute to about 63% of Nepal’s 2,991 MW installed capacity, argue the verdict stalls hundreds of projects worth 25,000 MW and threatens existing plants by blocking crucial transmission lines.

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.

Report reveals severe impact of last year’s drought on Amazonian communities
- A new U.N. report documents some of the most widespread and damaging impacts of the 2023-24 drought in the Amazon basin, which affected hundreds of thousands of Amazonian people.
- The main impacts were impeded transportation, drinking water shortages, deaths of aquatic wildlife and wildfires.
- In 2023, the drought led to a loss of 3.3 million hectares (8.1 million acres) of surface water relative to 2022 and nine Amazon countries experienced extremely high temperatures and their lowest rainfall in 40 years.
- Researchers warn that droughts are expected to worsen as climate change continues.

A forest garden project attempts to expand into the Sahel
- A project in the Sahel and East Africa claims to fight both soil erosion and poverty through regenerative agroforestry.
- U.S.-based NGO Trees for the Future (TREES) trains farmers in what it calls the forest garden approach, an ancient model to plant diverse species next to each other.
- The approach is one of seven selected by the U.N. as a world restoration flagship program and aims to scale up massively to plant a billion trees by 2030.
- However, some experts say the potential for scaling up is limited, especially in the semiarid Sahel region, given the need for easily accessible sources of water.

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.

Deadly landslide and flooding in Colombia and Venezuela linked to rapid urbanization
Heavy rainfall in Colombia and Venezuela caused deadly landslides and widespread flooding in June. A new analysis now points to rapid urbanization, deforestation, mining and overgrazing as having reduced the region’s climate resilience. “The rapid growth of population and informal settlements in areas prone to landslides, particularly in Colombia, puts people and infrastructure at risk,” […]
Tropical forest roots show strain as changes aboveground filter below
- Tropical forest plant roots have not received as much research attention as aboveground vegetation. This knowledge gap affects our understanding of how rainforests adapt to change, including their ability to capture and store atmospheric carbon.
- An emerging field of research is looking at how root systems respond to global change. New evidence dramatically underlines the outsized importance of tropical forests in the global carbon cycle. Tropical forests represent one of the world’s largest carbon sinks, largely thanks to plant roots, which add carbon to soils.
- Despite the challenge of studying tiny roots hidden underground, researchers are uncovering important insights. Some tropical forests send roots deeper into the soil under dry conditions, possibly seeking moisture, which may aid in drought tolerance. Others seem unable to do this, making them more vulnerable to climate change.
- Recent plant root studies are confirming the immense stress tropical rainforests are under, with conditions changing faster than roots belowground can adapt. Knowing more precisely which forests can, and can’t, tolerate escalating climate change and other stressors could better inform management and conservation decisions.

How private funding helped one NGO survive the USAID cuts
- After the U.S. government announced large cuts to USAID funding earlier this year, NGOs that relied on it were left in a state of uncertainty, with some needing to suspend activities or lay off staff.
- NGOs like World Neighbors that relied largely on private funding say this focus comes with several advantages and has helped it continue its work with little interruption after the USAID cuts.
- While government funding is often vulnerable to fluctuations in national politics, private funding also comes with its own challenges, such as smaller grants and more competition.
- Experts say a blend of government and private funding could be the best option for international NGOs seeking to support Indigenous peoples and other local communities to conserve or restore their lands.

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.

As Thailand’s fishing cats face habitat loss & conflict, experts seek resolution
- Fishing cats have lost vast swathes of their former range in Thailand, where decades of wetland conversion to fish farms, shrimp ponds and plantations have decimated their numbers.
- With habitats shrinking, these wild cats have been driven to living in human-dominated landscapes, where conflicts often arise.
- Fishing cats perceived as competing with farmers for fish and chickens are sometimes killed in retaliation.
- Activists and NGOs are working to reduce these conflicts and encourage landowners to preserve patches of remaining habitat suitable for the cats.

Ancient Himalayan village relocates as climate shifts reshape daily life
SAMJUNG, Nepal (AP) — A Himalayan village in Nepal has vanished — emptied by climate change. Samjung, perched in the high-altitude Upper Mustang region, was once home to a few dozen yak herders and barley farmers. But its streams dried up and snowfall disappeared. Then, a sudden flood destroyed many homes. That was the last […]
Two coasts, one struggle for octopus fishers battling overfishing and warming waters
- In Spain and Mexico, demand for octopus is up, but octopus populations are down.
- In both countries, artisanal octopus fishers are sticking to traditional fishing techniques while joining eco-certification schemes with tighter regulations, hoping to protect not just the cephalopod population, but their own livelihoods.
- But while this may offer a lifeline to the fishers’ economies, it may only work well for the octopus populations when all fishers in an area join in, experts say — and that’s not the case in Mexico, where illegal octopus fishing is rampant.
- Moreover, factors beyond fishers’ control, like warming waters, may affect the fishers and the octopuses alike.

Bitcoin boom comes with huge intensifying environmental footprint
- Bitcoin is often portrayed by promoters as existing in a separate cyber universe, distinct from the biological world. This view is far from reality, say critics, who point to bitcoin’s serious and escalating environmental impacts, with its global spread also raising environmental justice concerns.
- Bitcoin mining demands huge amounts of computing power and is an energy hog. It monopolizes entire data centers that are currently multiplying globally. Most of the energy needed to mint bitcoin comes from the burning of fossil fuels, which produces significant carbon emissions, worsening climate destabilization.
- Bitcoin data centers need huge amounts of water for cooling. The semiconductors required for mining are made in a process using toxic PFAS (forever chemicals). Bitcoin equipment and processing chips at the end of life also add to global e-waste. Despite these harms, bitcoin is poised for explosive growth
- Prominent influencers, including U.S. President Donald Trump, cheerlead loudly for bitcoin. Trump has said that “America will become the world’s undisputed bitcoin mining powerhouse.” His son, Eric Trump, has debuted American Bitcoin, a bitcoin mining firm. Neither Trump has addressed bitcoin’s global environmental costs.

From catching fish to picking trash, Thailand’s sea nomads are forced off the water
The Moken, a nomadic seafaring people in Thailand, have for generations lived most of their days at sea, moving from one place to another, fishing and foraging. However, with protected areas and increasing tourism restricting their access to fishing, and fish populations declining, the Moken are no longer able to follow their traditional way of […]
Of mushrooms and mycelium: How fungi are powering eco-friendly solutions
Often hidden from view, fungi are a critical part of our ecosystems. Some can be eaten as mushrooms; others help trees and forests thrive. But that’s not all: they’re also helping us create low-cost, sustainable housing materials and additional income for farmers, says Gabriela D’Elia, director of the Fungal Diversity Survey and a fungi enthusiast, […]
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.

After crackdown on illegal miners, Indigenous Munduruku still grapple with health aftermath
- In November 2024, the Brazilian government launched an operation to oust illegal gold miners from the Munduruku Indigenous Territory in the Amazon Rainforest.
- However, there was little government action to address health issues in the aftermath of the destruction wrought by gold mining, Indigenous leaders and experts say.
- A wide range of diseases linked to mercury contamination and other environmental destruction derived from illegal gold mining spread in Munduruku lands, including diarrhea, itchiness, flu, fever, childhood paralysis and brain problems.
- Munduruku leaders sent a letter to the federal government requiring actions to provide health assistance to their people, detailing a list of required actions, including measures to combat mercury contamination, malaria, food insecurity and lack of drinking water.

Heavy rains inundate northeast India
Dozens of people are reported dead amid torrential rains over the past week in India’s northeastern region, local media reported. The most heavily affected states are Assam and Arunachal Pradesh. In Assam, more than 640,000 people have been affected as the Brahmaputra River and its tributaries overflowed beyond danger levels, flooding many areas. Around 40,000 […]
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.

Marine artificial upwelling, problematic climate solution slow to advance
- Artificial upwelling is a form of geoengineering that aims to use pipes and pumps to channel cool, nutrient-rich water from the deep ocean to the surface. In doing so, it could fertilize surface waters, prompting the growth of plankton, which can then absorb and store large amounts of atmospheric carbon.
- Long considered a potential marine carbon dioxide removal (CDR) method, artificial upwelling has more recently been coupled with seaweed farming to potentially soak up even more atmospheric CO2.
- But technological challenges have plagued open-water upwelling experiments, while environmentalists worry that large-scale use could ultimately prove ineffective and ecologically harmful.
- Experts state that though upwelling could prove a viable solution to improve fisheries and protect coral reefs from marine heat waves, more research is needed. Considering the rapid current pace of climate change, it’s debatable as to whether implementation at scale could come in time to stave off dangerous warming.

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.

Community-led system boosts fisheries in a corner of fast-depleting Lake Malawi
Lake Malawi’s fish stocks are declining, but one community stands apart: around Mbenje Island, a traditional fisheries management plan has ensured thriving fish populations for generations, Mongabay contributor Charles Mpaka reports. Landlocked Malawi is highly dependent on the lake, which supplies 90% of the country’s fish catch; more than 1.6 million people rely directly or […]
Study offers new tool to compare environmental impacts of crops
In a recently published study, researchers offer a new tool to compare how different crops affect the environment in different regions. Named PLANTdex, the tool assesses the environmental impact of a crop by considering five key indicators — greenhouse gas emissions, freshwater biodiversity loss, marine biodiversity loss, land biodiversity loss, and water resource depletion — […]
Report urges stricter mining standards to manage climate and social impacts
- A new report from the Mining Observatory finds that key mining states in Brazil are highly exposed to climate risks, water insecurity and environmental degradation.
- Mining for transition minerals can in some cases exacerbate the impacts of climate change on ecosystems and local communities in the states of Pará, Minas Gerais, Goiás and Bahia.
- Researchers told Mongabay that without better socioenvironmental safeguards, the expansion of transition minerals mining represents a “major” threat to these communities’ way of life and the preservation of ecosystems.
- The report urged governments and companies to implement stronger policy frameworks, climate adaptation strategies, robust oversight and better mechanisms to involve rights-holders in key decisions.

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.
- Damage to the river’s ecosystems is taking a toll on their livelihoods, with some forced to give up fishing for the more lucrative, but environmentally destructive, activity of river sand mining.

Rwanda’s Olivier Nsengimana inspires protection for gray crowned cranes in East Africa
- Ten years ago, the gray crowned crane (Balearica regulorum), faced with habitat loss and capture for illegal trade, was quietly slipping toward local extirpation in Rwanda.
- The Rwanda Wildlife Conservation Association (RWCA), led by veterinarian Olivier Nsengimana, has been at the forefront of a campaign to end the keeping of cranes as pets, rehabilitating many captive birds and releasing them into the wild.
- The association is also enlisting community members to strengthen protection of the cranes’ wetland habitat from encroachment and damage — a strategy that it is extending to neighboring countries via partnerships with other NGOs.
- For these efforts, Nsengimana has been awarded the 2025 Whitley Gold Award, making him a two-time winner after he first received the award in 2018.

In Brazil’s Jequitinhonha valley, communities share how to reduce lithium mining impacts
- In southeastern Brazil’s Jequitinhonha Valley, a region that is home to up to 85% of the country’s known lithium deposits, residents say the arrival of the mining company Sigma Lithium brought new community conflicts and issues with their water supply.
- Some researchers say decisions concerning where and how to mine, as well as the types of consultation practices companies use, result in different levels of impact, but that there’s no way governments can ensure corporate responsibility.
- Local communities in the Jequitinhonha Valley have a blueprint on how companies can improve relations and mitigate impacts.
- Sigma Lithium did not respond to Mongabay’s request for a comment, but its website states its mission is to support the growth of the electric vehicle industry as a producer of sustainable lithium.

Eucalyptus for Brazil’s steelmaking dries out communities in Minas Gerais
- Eucalyptus plantations in Brazil’s Alto Jequitinhonha Valley, grown to make charcoal for the steel industry, have drastically reduced local water resources, harming rural communities, locals and experts warn.
- Despite years of complaints by a local NGO, Aperam, the steelmaking company that owns the plantations, continues to hold FSC certification for sustainable forestry. A recent audit, however, has flagged problems in its most recent assessment for certification.
- Studies show that eucalyptus plantations in the region have lowered groundwater levels by 4.5 meters (nearly 15 feet) since the mid-1970s, jeopardizing the water supply for local communities and their livelihood.
- Aperam also profits from its plantations by producing biochar from eucalyptus waste, which it uses to boost soil carbon sequestration, and selling the concept as a form of carbon removal to companies looking to offset their own emissions.

Bolivian communities push back against foreign-backed lithium projects
- In 2024, Bolivia’s state-owned lithium company, signed contracts worth a combined $2 billion with Russian and Chinese companies to mine lithium from Salar de Uyuni in the country’s southwest.
- Local communities already experiencing water shortages say they’re concerned the projects will divert large amounts of freshwater from agricultural lands.
- Experts have pointed out inconsistencies with the contracts, including the lack of environmental impact assessments required under Bolivian law, and the lack of community consultation.
- Bolivia holds an estimated 23 million metric tons of lithium reserves, or about a fifth of the global total, which is in growing demand for production of electric vehicle batteries.

Lithium Triangle mining may strain water sources more than expected, study says
- Measuring water availability for lithium extraction can still be unpredictable, especially in the high-altitude Lithium Triangle in Chile, Argentina and Bolivia.
- Current models can overestimate how much water is available, potentially exacerbating scarcity for local communities, according to a new study in Communications Earth and Environment.
- The study suggests using a more accurate model as well as improving transparency and resources for gathering observational data where lithium is being extracted.

Uttarakhand’s extreme weather wreaks havoc on crops, livelihoods & futures
- In Uttarakhand, extreme weather events like droughts, erratic rainfall and hailstorms have severely affected farming, leading to lower crop yields, increased pests and financial distress for farmers.
- Festivals and agricultural practices linked to seasonal changes are losing their significance due to shifting flowering and harvesting periods, affecting both cultural traditions and livelihoods.
- Reduced snowfall and irregular rainfall have led to water shortages, depleting natural aquifers and springs that local communities rely on for drinking water and irrigation, while forest fires, intensified by extreme heat, have caused loss of human life and biodiversity.
- Climate change is also impacting tourism and small businesses, with rising temperatures and unpredictable weather affecting visitor numbers and local economies.

Floods devastate normally arid parts of Australia’s Queensland
Intense flooding submerged usually dry areas of Queensland state in eastern Australia during the last week of March, forcing many people to evacuate and leave their livestock behind. David Crisafulli, the Queensland premier, called the floods “unprecedented” as several places in western Queensland recorded the worst floods in the last 50 years, CNN reported. Some […]
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.

Photos: Ethiopian farmers blend tradition, innovation to sustain centuries-old agriculture
- For more than 400 years, the people of the Konso highlands in Ethiopia have used terracing and traditional farming methods to adapting to their harsh environment, building a globally recognize agricultural system on steep, erosion-prone land.
- However, in recent decades, climate change has altered once-predictable weather patterns, making it harder for small-scale farmers to maintain their traditional farming practices and secure their livelihoods.
- Farmers are adjusting to changing weather patterns by blending traditional farming methods with new techniques, aiming to safeguard their livelihoods and ensure the land remains fertile and productive.
- While experts acknowledge farmers’ efforts to adapt, they warn that these efforts alone will not suffice as climate change impacts intensify, stressing the need for external support to sustain local livelihoods and preserve traditional farming practices.

Drowned lands and poisoned waters threaten Peru’s campesinos and their livestock
- Peru’s Lake Chinchaycocha, also known as Lake Junín, and its endemic species are under threat in part due to environmental problems caused by mining activities, hydroelectric power operations, the discharge of urban wastewater and the overexploitation of resources.
- Campesino communities nearby have lived for decades with this contamination, which they blame for killing so much livestock that one community had to open a cemetery specifically for animals.
- For several months a year, due to the flooding by the nearby dam, homes and pastures are inundated with contaminated water, forcing residents to migrate to higher ground.
- Studies have confirmed the presence of heavy metals in the water exceeding environmental quality standards, but there haven’t been any studies yet linking this to human and livestock health impacts in the region.

In ‘The Battle for Laikipia,’ the human face of resource conflict in Kenya
- During Kenya’s colonial era, Maasai, Samburu and other pastoralist communities were evicted from what is now Laikipia county to make way for British settler farms.
- Today, much of that land is still concentrated in the hands of British descendants, as well as other Kenyans and foreign investors who own large ranches and wildlife conservancies.
- Over the past decade, some of these ranches have been embroiled in conflicts with Laikipia’s pastoralist communities over access to water and forage for their herds.
- These conflicts are the subject of “The Battle for Laikipia,” a documentary film shot over seven years and to be screened at the 2025 D.C. Environmental Film Festival, where Mongabay is a media partner. Mongabay spoke to Daphne Matziaraki, one of the filmmakers.

This World Water Day, Mongabay looks back at some of its coverage from 2024 on how local communities are […]
With climate change, cryosphere melt scales up as a threat to planetary health
- Earth’s cryosphere — comprised of ice sheets, glaciers, permafrost and snowfall — is in a rapid state of flux due to escalating climate change, with numerous studies underlining the grave risks posed by the thaw.
- Today, that worldwide meltdown poses new threats to human lives — endangering freshwater supplies and food security while increasing the risks of natural disasters and disease outbreaks. Cryosphere loss poses immense dangers to the environment, agriculture, economy and society according to a new report.
- If emissions continue unabated, these problems will only worsen. Scientists warn of compounding risks as cryosphere melt escalates, including sea level rise, the slowing of ocean currents, and the triggering of feedbacks that will add to climate change.
- 2025 is designated the International Year of Glaciers’ Preservation. Experts are calling for drastic cuts to carbon emissions because each fraction of a degree of warming avoided counts toward the preservation of the cryosphere along with the ecosystem services that ice, snow and permafrost provide.

A tale of two cities: What drove 2024’s Valencia and Porto Alegre floods?
- In 2024, catastrophic floods occurred in the cities of Porto Alegre, Brazil, and Valencia, Spain. These two record floods number among the thousands of extreme weather events that saw records for temperature, drought and deluge shattered across the globe. Such horrors have only continued in 2025, with the cataclysmic wildfires in Los Angeles.
- Scientists have clearly pegged these disasters to carbon emissions and intensifying climate change. But a closer look at Porto Alegre and Valencia shows that other causes contributed to the floods and droughts there, and elsewhere on the planet — problems requiring nuanced but Earth-wide changes in how people live and society develops.
- Researchers especially point to the drastic destabilization of the world’s water cycle, which is increasingly bringing far too little precipitation to many regions for far too long, only to suddenly switch to too much rain all at once — sometimes a year’s worth in a single day, as happened in Valencia when 445.5 mm (17.5 inches) fell in 24 hours.
- The problem isn’t only CO2 emissions, but also local deforestation and hardened urban infrastructure that promote flooding. But what may be seriously underestimated is how large-scale destruction of forest, marshland and other vegetation is dangerously altering rainfall patterns, a theory proposed decades ago by a little-known Spanish scientist.

Yaku Raymi: The Quechua Ritual to Save a Glacier
SANTA FE, Peru — What happens when a glacier dies? In the community of Santa Fe, in Peru, water is disappearing, animals are dying due to a lack of pasture and rainfall has become sporadic. The community members know that climate change is affecting the apu, or mountain god, but they say that transforming a […]
Lake Chad isn’t shrinking — but climate change is causing other problems
- Contrary to popular conception, Lake Chad is not shrinking; new research shows that the volume of water in the lake has increased since its low point in the 1980s.
- However, more intense rain in the region, coupled with the impacts of historic drought, increases the risk of flooding.
- The region is also plagued by continuing conflict and insecurity, making to harder for people to adapt to the impacts of climate change.
- A Lutheran World Federation project is working with communities in the Lake Chad Basin on sustainable agriculture and fisheries, land restoration, conflict resolution and more.

Funerary practices in Fiji protect marine areas while honoring the deceased
- Indigenous (iTaukei) people across Fiji have historically protected their freshwater and marine areas in memory of chiefs and community members who have passed away. These are called aquatic funerary protected areas (FPAs).
- Researchers published a study to shine a light on this sustainable resource management practice, which they say could present a community marine conservation solution in the region but is largely absent from scientific literature and rarely implemented as a strategy.
- FPAs differ in size and practice but can stretch from shoreline to fringing reefs and tend to ban fishing and harvesting of many species for 100 nights after they are declared.
- From 1960 to 2019, communities established a total of 188 FPAs where 44% of FPAs were protected for 100 nights, and 47% protected all resources and associated ecosystems form fishing and harvesting.

In Nepal, a eucalyptus boom became an ecological cautionary tale
- Nepal’s Sagarnath Forest Development Project which ran a reforestation program from 1977-1984 and introduced eucalyptus as a fast-growing, low-maintenance solution for deforestation and fuelwood needs.
- While eucalyptus initially thrived, it depleted soil moisture and negatively impacted nearby crops, leading to reduced yields and financial losses for the farmers who had replaced traditional crops like rice and mustard with large-scale eucalyptus plantations.
- Discontent over eucalyptus’s effects, and the lack of guidance by those who promoted the planting scheme, led to widespread removal of trees, legal disputes among farmers, and complaints to local governments.
- Experts say such large-scale exotic tree plantations are no longer permitted under national and international biodiversity laws, with the project’s failure highlighting the importance of considering ecological sustainability, soil health and informed decision-making in reforestation efforts.

‘Silent killing machines’: How water canals threaten wildlife across the globe
- Water canals worldwide are causing widespread wildlife drownings, with significant losses recorded in Argentina, Mexico, Spain, Portugal and the U.S., particularly impacting threatened species.
- Scientists emphasize the lack of awareness and research on this issue, warning that canals act as “wildlife traps,” exacerbating biodiversity loss and habitat fragmentation.
- Proposed solutions include covering canals, installing escape ramps, redesigning structures, and implementing country-specific mitigation strategies to balance irrigation needs with wildlife conservation.

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.

How a Philippine town is dealing with the fallout of its own popularity
El Nido in the Philippines was once a small fishing town, but promotion on social media over the last decade led to a dramatic influx of tourists. Tourism has helped the local economy, but also resulted in coastal water contamination, Mongabay’s Keith Anthony Fabro reports. Home to 50,000 residents, El Nido welcomed 10 times that […]
In Ecuador, a mountain shrub could hold the key to restoring a precious ecosystem
- The spread of agriculture, including the use of fires to clear native vegetation, have devastated Ecuador’s páramo, a high-altitude ecosystem that represents a critical source of drinking water for local communities.
- Reforestation of frailejones, a rare shrub species that helps trap humidity from the air and filter water to the ground, may prove key to restoring the ecosystem.
- A privately financed initiative in Ecuador is researching how to grow the shrub at scale in a nursery for mass replanting, but faces teething challenges in this first-of-its-kind initiative for the country.

Better government policies could help as migratory birds lose habitat in Bangladesh
- Recent studies indicate a steady decline in the number of migratory water birds in Bangladesh over the last few years.
- Researchers said the key threats to migratory birds include habitat loss, cattle grazing in bird habitats, domestic duck farming and conservation mismanagement.
- They underscore the need for a coordinated effort among livestock, agriculture and environment ministries.

Seeking the ‘humanity–wetland’ balance: Interview with Zimbabwean activist Jimmy Mahachi
- For the past decade, Jimmy Mahachi has advocated for his community’s right to water and the preservation of the Cleveland Dam wetland, a peri-urban wetland in the Zimbabwean capital Harare.
- The wetland is threatened by sand mining, development and the overexploitation of water resources.
- Some residents of the New Mabvuku suburb where Mahachi lives haven’t had running water for more than 30 years, forcing them to collect water from unprotected and even contaminated sources.
- In an interview with Mongabay, Mahachi sheds light on the pressures on environmental activism in Zimbabwe and the connection between humanity and wetlands.

This contamination is driven by both natural geochemical processes and human activities like agricultural and industrial practices, reports contributor Esha Lohia for Mongabay India. To understand the state of groundwater in India, the Central Ground Water Board (CGWB) assessed more […]
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.

Brazil’s shipping channel plans in Amazonian rivers will worsen climate change, experts warn
- Dredging and rock-blasting ever-drier rivers for new channels in Brazil might not achieve agribusiness’s goal of cheaper, year-round transport, experts warned, suggesting existing railways as price-comparable and more climate-resilient.
- Though waterway transport is promoted as lowering emissions, in fact proposed new shipping channels on the Tocantins and Madeira rivers increase carbon emissions and deforestation, experts told Mongabay.
- New shipping channel plans used old water data, stopping in 2017 for the Tocantins channel, and didn’t do climate risk projections or climate impact studies. Experts urge these studies must be done, or risk tens of billions of investments in rock-blasting and dredging river beds, leaving “ruins” and “abandoned projects.”
- An August lawsuit by federal prosecutors charges that licensing of rock-blasting and dredging in a 500-km stretch of the Tocantins River in Brazil is an illegal “trick” to circumvent legally required full environmental review of the whole Araguaia-Tocantins channel, for which an economic-technical feasibility study was never done. In March 2022, Ibama’s licensing director determined it was “unviable.”

‘Time is water’: A cross-border Indigenous alliance works to save the Amazon
- A transboundary Indigenous peoples’ alliance has been working in Ecuador and Peru to protect the Amazon Basin in the face of climate change impacts.

- In this essay, three recent fellows share some of the biggest lessons they learned through the reporting they published during the fellowship.
- As these reflections from India, Brazil and Nigeria show, there are many areas of overlap experienced among communities across regions and continents.

As lithium mining bleeds Atacama salt flat dry, Indigenous communities hit back
- The Council of Atacameño Peoples filed a complaint in October 2024 against lithium mining companies operating in Chile’s Atacama salt flat, accusing them of causing the land to sink around their extraction wells.
- The complaint was based on findings from a study published in July that revealed portions of the salt flat are subsiding by up to 2 centimeters, or nearly an inch, per year.
- Scientists warn that one of the main consequences could be the loss of the aquifer’s storage capacity.
- They also point out that since the salt flat lies on a tectonic fault, the subsidence could spread further, including to two protected areas in the region that are home to flamingos and other rare wildlife.

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.

Water returns to Amazon rivers amid historic drought
The Amazon River and its tributaries, which make up the largest freshwater basin in the world, are showing signs of recovery after dropping to record-low levels between September and November 2024. Abnormally low rainfall and high temperatures across the Amazon caused water levels to plummet, shutting down river transport, isolating communities and leaving industries without […]
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.

Severe drought in Peruvian Amazon isolated more than 130 Indigenous communities
- A severe drought that spread over recent months in Peru’s Loreto and Ucayali regions led to the isolation of more than 130 communities.
- Record low river levels affected the navigation of boats that deliver food and supplies as well as the health and livelihoods of communities that rely on fish for food and trade.
- Indigenous leaders from isolated communities have criticized the state for failing to deliver emergency assistance, such as drinking water and medical supplies.
- The frequency and intensity of extreme drought in the Amazon will continue to increase substantially due to climate change, experts warn.

Land use change impacting seven planetary boundaries, solutions urgent, say scientists
- A new scientific report lays bare the stark impacts of land-system change and land degradation on planetary health, while also offering solutions to these problems. The report was published on the eve of the 16th session of the UN Convention to Combat Desertification, running Dec. 2-13 in Riyadh, Saudi Arabia.
- Seven of nine planetary boundaries are now adversely impacted by unsustainable land use and other land practices, the report finds. Six of those boundaries are already transgressed, having moved beyond their safe operating space for humanity and into the high-risk zone.
- Scientists warn that the seriously degraded land use boundary, interacting with the other transgressed planetary boundaries, could result in a domino-effect that may rapidly push Earth systems past dangerous and irreversible tipping points, threatening life as we know it.
- Unsustainable agricultural practices are a leading driver of land use degradation globally, responsible for vast amounts of greenhouse gas emissions, the majority of deforestation and freshwater use. Urgent measures are needed to restore ecosystems, shift to sustainable agriculture, and prevent further degradation.

Controversial U.S. Supreme Court decision threatens the country’s inland wetlands with new development, study says
- In its May 2023 decision Sackett v. Environmental Protection Agency, the U.S. Supreme Court all but gutted the nation’s Clean Water Act of 1972, only maintaining protections for large waterways and opening inland wetlands for development.
- An estimated 7 million to 36 million hectares (17 million to 90 million acres) of nontidal wetlands may have lost federal protections, according to a new analysis.
- Filling wetlands would harm downstream water quality, eliminate critical ecological habitats and elevate the risk of flooding, concerned researchers say.
- The largest wetland areas at risk in the U.S. are near the Gulf of Mexico and Atlantic Ocean coasts and around the inland Great Lakes.

Kenya blames and evicts Ogiek people for deforestation, but forest loss persists
- Long-running evictions of Indigenous Ogiek communities from Kenya’s Mau Forest, whom the government blames for deforestation, haven’t led to any letup in rates of forest loss, satellite data show.
- A human rights court ruling in 2017 recognized the Ogiek as ancestral owners of the Mau Forest and ordered the Kenyan government to compensate them, but it’s done little since then.
- Preliminary satellite data and imagery for 2024 indicate the Mau Forest will suffer extensive losses this year, even after the government evicted more than 700 Ogiek in November 2023.
- The country’s chief conservator of forests has cast doubt on the findings of increased deforestation, while a top official responsible for minorities and marginalized peoples says forest communities can be destructive.

PNG climate migrants sail away with native trees to their new home
Residents of the Carteret Islands in Papua New Guinea are on a “green migration,” contributor Thibault Le Pivain reports for Mongabay. The islanders are leaving their homes due to food shortages resulting from environmental degradation and rising sea levels, and sailing to a larger island in the country, taking with them plants that play important […]
Western Kenya’s most important water-capturing forest is disappearing, satellites show
- Mau Forest is one of the largest forests in East Africa, and the most important water catchment in western Kenya, providing water for millions of people.
- Mau is also home to a plethora of wildlife, including endangered species such as African bush elephants (Loxodonta africana), African golden cats (Caracal aurata) and bongo antelopes (Tragelaphus eurycerus).
- But Mau lost some 25% of its tree cover between 1984 and 2020, and satellites show continuing loss.
- The primary drivers of deforestation are agricultural expansion, including slash-and-burn farming for cattle grazing and crop cultivation.

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.

As climate change upends Ethiopia’s pastoral wisdom, adaptations can help
- In the face of climate change, pastoral and agropastoral communities in eastern Ethiopia remain at the receiving end of worsening droughts and climate shocks that have taken a toll on animal rearing and traditional livelihoods.
- For generations, pastoralists and agropastoralists across the country have used traditional knowledge and weather forecasting for preparedness and drought conditions.
- But these techniques are no longer as effective in the face of frequent unpredictable dry spells and population pressures on pasture.
- Researchers suggest combining this traditional knowledge with innovative strategies to help pastoralists gather real-time data on water conditions that can be key to drought adaptation in the region.

In a Noah’s Ark move, PNG migrants bring thousands of trees to safer ground
- Facing sea level rise and food insecurity, 17 families from the Carteret Islands have relocated to nearby Bougainville, bringing hundreds of specimens of trees and plants, representing dozens of species, across a small stretch of ocean.
- They’ve planted more than 175,000 plants, breathing life into a forest on new lands donated by the Catholic Church.
- This “green migration” is helping them preserve their lifestyle and identity, sources say, echoing the journey of early Polynesian settlers who carried “canoe plants” as they sailed and settled across the Pacific.
- Scientists say green migrations could become part of climate relocation planning, but there also needs to be careful consideration of whether species can be moved and become unsustainably invasive.

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.

Fresh calls for oil giants to pay $12 billion for Niger Delta pollution
The governor of Nigeria’s Bayelsa state has renewed calls for oil companies like Shell and Eni to pay $12 billion to clean up the pollution from their operations in the state over the past 50 years. The call comes more than a year after a Bayelsa state-appointed commission released its report in May 2023 detailing […]
In Kenya, a water fund brings to light Indigenous cultural identity issues
- Two years into its implementation, the Eldoret-Iten Water Fund (EIWF) in Kenya is helping to protect vital water resources, restore degraded forests and farmlands and work with local communities.
- While the EIWF has seen considerable success so far, several hurdles have emerged — including disputes with the Sengwer Indigenous community.
- The issues with the Sengwer community stem at least in part from decades of controversy over cultural identity and names, dating to colonial times.
- Despite these challenges, the EIWF, administered through The Nature Conservancy, has made progress and local farmers say they are hopeful about the future; for further details on the EIWF, see Part I of this story.

A Kenya water fund partners with farmers to protect vital resources
- Kenya’s Eldoret-Iten Water Fund (EIWF) is one of dozens throughout the world, established to address threats to important water supplies.
- Administered through The Nature Conservancy, the EIWF’s objectives include partnering with thousands of local farmers to adopt sustainable soil and water conservation practices, restoring and protecting more than 120,000 hectares (300,000 acres) of degraded forests and farmlands, planting more than 1 million trees, reducing sediment flow into rivers and supporting farmers with rainwater harvesting.
- The EIWF also works with local Indigenous communities and includes projects such as beekeeping.
- The EIWF is a response to years of farming practices, population growth, deforestation for charcoal and wood and other factors that have diminished and threatened local water supplies.

Study warns that loosened legislation is driving deforestation in Bahia’s Cerrado
- Unlike Amazonia, where illegality is the rule, authorized deforestation is a greater concern for researchers and environmentalists in Bahia’s Cerrado.
- A new book shows how the appropriation of water by agribusiness is intensifying conflicts in western Bahia, where both deforestation and cattle farming are spreading rapidly.
- Researchers view Brazilian agribusiness operations as agrarian extraction—a model with high social and environmental impact which concentrates wealth, similar to mineral extraction.

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

Chilean Indigenous association participates in key study for lawsuit against mining
- In a unique model for Latin America, a council of Lickanantay people in northern Chile created an environmental unit made up of hydrogeologists, engineers and environmental monitors from the territory’s communities to monitor the territory.
- Their study with a national university shows that the La Brava lagoon, located on the edges of the Atacama salt flat, is fed in part by the salt flat’s brine, which makes it vulnerable to mining activities established in the heart of the salt flat.
- Findings from the study were key in a lawsuit brought by the state defense council against three mining companies for irreparable damage to the Monturaqui-Negrillar-Tilopozo aquifer, the main water source for these lagoons.

Despite court ruling, Yaqui water rights abuses ignored
- For decades, the Yaqui peoples in the northwestern Mexican state of Sonora have been fighting to defend their rights to the Yaqui River, which is sacred to the Indigenous tribe and has been drained of all its water in their territory after decades of overexploitation, unequal water distribution and droughts.
- In 2010, the government approved the construction of an aqueduct, known as the Independencia Aqueduct, to supply water to several cities in the state, which was later found to be a violation of the tribe’s rights.
- Despite a favorable court ruling, which found that the Mexican government did not consult the Yaqui tribe before the aqueduct’s approval, it did not suspend its construction, which was inaugurated in 2012, despite evidence that it would cause irreparable damage to the community.

Community-led wetland restoration may hold key to Harare’s water crisis
- In Zimbabwe’s biodiverse but fast-developing capital city of Harare, a small community has formed a wetland restoration project, known as Conservation of Monavale Vlei, to protect biodiversity and prevent degradation.
- The Monavale wetlands are under threat in part due to environmental problems caused by development, inadequate infrastructure and poor waste management.
- Over the years, the city’s water tables have been falling, as Harare extracts groundwater faster than the aquifers are replenished to meet the demands of its growing population. This issue combined with drought results in a serious water crisis.
- By replicating the Monavale Vlei model, which supports rich biodiversity, residents and experts said the city could benefit from the many ecosystem services the project provides, including water storage, groundwater recharge and water purification.

High CO2 levels are greening the world’s drylands, but is that good news?
The increased concentration of CO2 in the atmosphere since pre-industrial times isn’t just driving climate change — it’s also making much of the world’s drylands greener with increased plant growth. This is known as the CO2 fertilization effect, and politicians sometimes cite it to rhetorically downplay the negative global impacts of climate change, saying it’s […]
Ever-smarter consumer electronics push world toward environmental brink
- Semiconductor microchips are the beating heart of the digital age — processing vast, ever-growing volumes of data on our smart phones, computers and other electronic devices, and on data center servers worldwide.
- As manufacturers compete to produce the ever-smaller, more powerful electronic devices consumers want, new state-of-the-art silicon chips must be designed to handle exponentially advancing computing challenges.
- But the sourcing and manufacture of these increasingly complex silicon chips is material-, energy- and water-intensive, doing major environmental harm — producing major carbon emissions and polluting with PFAS and other toxins.
- Also, the smaller and more integrated chips become, the harder they are to recycle, creating vast sums of e-waste. Experts say governments need to ensure companies embrace environmental stewardship and circular economy standards.

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.

In Chile, a copper mining project tainted by environmental damage sues 32 locals
- In 2023, the Los Pelambres Mining Company’s “Operational Adaptation” project was unanimously approved. The project will allow for the relocation of pipelines that transport copper concentrate, the extension of the mining project’s lifetime, and the construction of a desalination plant.
- The mining company’s extensive history of environmental damage — which includes oil, copper concentrate and industrial water spills — has residents of Pupío concerned, especially because the new pipelines will be installed only 100 meters (330 feet) from their homes.
- However, the opposition of many residents to the new pipelines caused the mining company to bring a lawsuit against them. The 27 defendants are in addition to another five people from Choapa Viejo who are also facing a legal process after protesting for solutions to the environmental damage caused by the company.
- However, in response to the residents’ opposition, the mining company has sued 27 locals. Another five people from Choapa Viejo are also facing legal proceedings after they protested, demanding solutions for the environmental damage caused by the company.

Bangkok turns to urban forests to beat worsening floods
- Bangkok is launching city forests to help beat flooding by soaking up excess rainwater runoff.
- A new park slated to open in December will feature 4,500 trees, a floodplain and a weir to slow the flow of water; another newly opened $20 million city forest acts as a sponge during the monsoon season.
- Bangkok is sinking, and fast: according to the World Bank, 40% of the Thai capital could be flooded by 2030.
- The key to solving the city’s flooding problem is to learn to live with water, not to rid the city of water, says one landscape architect helping to launch the urban forests.

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.

Drought forces Amazon Indigenous communities to drink mercury-tainted water
- River levels in parts of the Brazilian Amazon are even lower than in 2023, when the region experienced its worst drought.
- In the Munduruku Indigenous Territory, in Pará state, low river levels are forcing communities to drink water contaminated by mercury.
- Indigenous leaders call for immediate help while children suffer from diarrhea and stomachaches.

Crop fields make way for profitable orchards in Bangladesh, imperiling food security
- The mid-western region of Bangladesh has long been characterized by dry weather due to low rainfall. However, over the last four decades, the agriculture thrived here due to a government-run irrigation project that relies on groundwater.
- A few years ago, following a significant increase in rice production, but a decrease in the groundwater level, the government started rationing irrigation to save groundwater.
- Consequently, the farmers began to opt for alternative non-water intensive crops and converted their arable lands into orchards, cultivating fruits like mangoes and lychees.
- Experts feared that although the transition may bring a secure cash crop for the farmers, this change in agriculture could hamper the country’s overall food security.

Polluting copper mine in Java suspended as farmers decry lost crops
- A copper mine in Pacitan district on the island of Java has been temporarily closed by Indonesia’s mining ministry after contaminated irrigation water allegedly harmed food crops belonging to 200 families.
- A lawyer for the company, PT Gemilang Limpah Internusa, told Mongabay Indonesia the company would conduct remedial measures and aim to reopen the mine within months.
- In March, Mongabay Indonesia spoke with farmers in Pacitan who had suffered income losses in addition to uncertainty as to the future viability of their crops.

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.

Acre’s communities face drinking water shortage amid Amazon drought
- Acre’s population experienced a flood at the start of 2024 and is now suffering from water shortages due to the severe drought.
- Authorities have installed water tanks for residents of rural communities in Rio Branco, but supplies are insufficient.
- After the extreme drought of 2023, the Amazon is preparing for a new drought, which is already showing signs that it could surpass last year’s crisis.

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.

Uttarakhand villagers thirst for water as tourism, temps & development rise
- An influx of tourists and new residents to Uttarakhand, driven by heat waves and work-from-home options, is straining local resources, particularly water.
- Nearly 12,000 natural springs reportedly have dried up in recent years, with 90% of Uttarakhand’s population depending on these vital water sources.
- Widespread construction for tourism disrupts aquifers and natural water percolation, exacerbating water scarcity and affecting water quality; water sources are further threatened by changing rainfall patterns and rising temperatures.
- Local residents, especially women and marginalized communities, face increased hardships in accessing water amid growing allegations of water diversion by hotels.

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.

Cerrado’s current drought impossible without human-caused climate change: Study
- Since early 2000s, Brazil’s Cerrado has been suffering severe drought episodes, with water shortages affecting hydroelectric power, agriculture and water access. Its water supply has also been under pressure from encroaching agriculture and deforestation.
- Analysis of 700 years of climate data indicated an unprecedented drying trend that started around the 1970s, which experts say was made possible by human-induced warming, and not by climate’s natural variability.
- Researchers collected data from stalagmites in one cave in the state of Minas Gerais and built a climate record for the Cerrado.

In Sonora, communities fight mining to defend their water
- Since June 2, protesters have blocked mining company Grupo México from extracting water in the Sonoran town of Bacoachi, in northwest Mexico.
- Locals say the company has overexploited water resources during a regional drought, putting their livelihoods and public health at risk.
- The company owns the rights to more than half of the watershed’s total volume, according to a government analysis published in 2023.
- The ongoing protest comes as local advocacy groups are preparing to mark the 10th anniversary of an infamous waste spill from the same mine in August 2014.

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.

The nine processes that keep Earth stable
Modern humans, (Homo sapiens), evolved some 300,000 years ago. But modern human societies as we know them—think agriculture, animal domestication, and industrialization—developed only in the last 10,000 years or so. This was largely thanks to a stable climate that emerged around 12,000 years ago. The stability of the planet that allowed human civilization to flourish […]
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.

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.

Across Mexico, World Cup infrastructure threatens biodiversity and communities
- With Mexico co-hosting the FIFA World Cup in 2026, major infrastructure works in the country’s three host cities could have negative impacts on local biodiversity, activists say.
- In Guadalajara, conservationists express concern that new developments might undermine the local puma population, which has seen a comeback in the last seven years.
- In Mexico City, locals say they haven’t been consulted about new roads and building projects that could threaten their water resources as well as tree cover.
- In Monterrey, works planned near a protected area threatens fauna and flora conservation, experts say.

Activists blame policy failures over climate change for Nepal Terai’s water crisis
- Deforestation and unregulated extraction of resources in the youngest and most fragile of the Himalayan ranges have disrupted groundwater recharge and increased soil erosion, contributing to the current water crisis.
- Activists criticize the government for blaming global climate change to deflect from local accountability and for neglecting Chure’s conservation while focusing on Himalayan snowmelt.
- Despite conservation efforts, government plans to export construction materials from Chure continue, risking further environmental damage and criminal influence.

‘Water grabs’ pose big threat to farmers amid water crises
- A new report by IPES-Food shows how investors and agribusiness are taking control of water in Latin America by purchasing rights to land or water to secure access and grow water-intensive crops, such as avocados.
- The researchers say such deals take water away from local farmers and communities and puts it in the hands of agribusiness and investors, creating a crisis for local farmers who already face water shortages.
- In Chile’s Petorca province, a combination of climate change and water acquisitions by large agribusiness has put a strain on an already overwhelmed water system, forcing many residents to leave or buy water at high prices.
- The financial advantages large companies have over smallholders also mean they’re more likely to secure water over farmers when there’s little left.

Photos: Exploring Mexico City’s Aztec-era farms, the chinampas
- Chinampas are part of an agricultural system developed during the Aztec Empire in shallow lakes or marshes in the southern valley of what is today Mexico City.
- The system consists of elevated, narrow platforms used as fields that are surrounded by water canals, and is considered one of the most intensive and productive farming systems ever developed.
- However, for decades, chinampas have faced increasing threats due to urbanization, the overexploitation of water resources, water contamination and unregulated tourism, as well as the growing rejection of chinampa culture by traditional farmers and the loss of ancestral knowledge.

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.

Ancient farming system and campesino livelihoods at risk in Mexico City
- In the south of Mexico City lies a complex lake and canal system dotted with raised agricultural fields known as chinampas, which have been cultivated by campesino farmers ever since the Aztec Empire.
- Chinampa culture is under threat in part due to environmental problems caused by urbanization, the overexploitation of water resources, irregular settlements and unregulated tourism.
- Over the years, greater numbers of the chinampas’ farmers, known as chinamperos, have left the fields to work in the city, an issue that has led to the abandonment of 16,000 chinampas, according to researchers.
- Those who remain face several challenges, such as water contamination and drought, with little government support.

Water is key as study shows restoration of drained tropical peat is possible
- Rewetting of tropical peatland that was drained for agriculture can lead to the recovery of the native ecosystem, a long-term study of a former pulpwood plantation in Indonesia shows.
- Researchers studying the 4,800-hectare (11,900-acre) plot that was retired in 2015 by Asia Pulp & Paper (APP) found the water table had risen, soil carbon emissions had gone down, and native trees were springing up and replacing the planted acacia pulpwoods.
- They attributed these outcomes to APP’s efforts to rewet the peat by blocking the canals previously dug to drain the waterlogged soil.
- The findings suggest that “several million” hectares of peatlands in similar condition can be restored this way, “should plantation owners aim to restore forest in parts or all of their peatlands.”

An ancestral solution ensures water for Peruvian alpaca farmers, but is it enough?
- A community of alpaca farmers in the high Peruvian Andes is witnessing the loss of its mountain glaciers as a result of a warming climate and unseasonal droughts.
- In response, community members have turned to an ancestral practice of harvesting rainwater runoff and snowmelt, caching it in artificial lagoons that they can then tap to irrigate their alpaca pastures.
- Today, the community of Santa Fe, on the slopes of Mount Rit’ipata, has 41 of these lagoons, or qocha, but increasingly prolonged droughts mean it will need many more.
- Other communities across Peru have launched similar water harvesting initiatives, and while the government backs these projects, communities like Santa Fe are ineligible for state funding under a 2022 regulation.
