Loopholes undermine palm oil industry’s antideforestation pledges
- More than a decade after the palm oil industry adopted “No Deforestation, No Peat, No Exploitation” (NDPE) commitments, new satellite data show forest clearing for palm oil in Indonesia persists, with more than 31,000 hectares (nearly 77,000 acres) lost in 2025.
- Campaigners say deforestation increasingly slips through structural gaps in the system, including incomplete traceability, fragmented smallholder supply chains, and loopholes that allow companies linked to forest clearing to continue selling into supposedly deforestation-free markets.
- Investigators cite cases in Indonesia, the top producer of the commodity, as examples of how palm fruit from deforestation-linked plantations can still enter global supply chains through third-party mills and opaque ownership structures.
- Analysts warn these unresolved weaknesses could create major problems for compliance with the European Union Deforestation Regulation (EUDR), which will require firms to prove commodities sold in the EU are not linked to recent deforestation.

Indonesia seizes mercury shipment bound for illegal mines in the Philippines
- Inspectors at Jakarta’s Tanjung Priok Port found hundreds of individual containers of mercury hidden in carpets in a shipment bound for the Philippines in late April.
- Mercury is used in the so-called artisanal and small-scale mining sector to separate gold particles from ores recovered at illegal mines. However, the heavy metal is a severe neurotoxin that causes developmental disorders in children as well as devastating cognitive and physical impairments in adults.
- Pollution from mining has contaminated rivers, crops and fisheries, with studies linking exposure to serious health risks and reporting suggesting increased incidences of malaria transmission.
- Experts say the all-time high price of gold reached this year is driving more people to illegal mining sites, undermining international efforts to restrict the use and trade of mercury.

‘Same dangerous project’: Fury after Indonesia revives disputed mine
- Indonesia’s environment ministry has reapproved a controversial zinc and lead mine in North Sumatra, less than a year after the Supreme Court forced it to revoke the project’s earlier environmental approval over disaster-risk concerns.
- The revised environmental assessment replaces a proposed tailings dam with a plan to bury mining waste underground, but critics and independent experts say the mining company cannot realistically bury all of its waste and will still require a dangerous aboveground storage facility.
- Residents, activists and legal advocates argue the new approval is legally flawed because it relies on a framework already annulled by the Supreme Court, and say the company failed to conduct meaningful public consultation or provide key documents to affected communities.
- Communities opposing the mine say previous company activities have already caused environmental damage, flooding and water disruptions, and vow to continue fighting a project they fear could threaten lives and farmland in the earthquake-prone region.

What drives the trafficking of gibbons? Conservationists shed light on demand
As gibbon seizures reached a record high in 2025, conservationists warn that dismantling the illegal trade requires a deep understanding of the diverse motivations driving consumer demand, contributor Ana Norman Bermúdez reports for Mongabay. In 2025, authorities confiscated 336 gibbons between January and August alone, representing approximately 20% of all recorded seizures since 2016, according […]
Nine killed at illegal mine in latest Sumatra landslide tragedy as gold surge continues
- A mining accident in Indonesia’s West Sumatra province buried 12 miners on May 14, nine of whom were killed, following a period of heavy rain.
- The disaster is the latest fatal accident at an unpermitted mining site in the interior of Sumatra in recent years, with officials and civil society analysts saying the sustained high price of gold, which at the time of writing was threefold higher than six years ago, is drawing more people to illegal mines.
- Walhi, Indonesia’s largest environmental NGO, said at least 48 people were killed in West Sumatra, one of Indonesia’s 38 provinces, in the last 15 years.
- The green group said the true number could be much higher owing to the remote nature of the illegal industry.

Smallholders are not the weak link in forest protection (commentary)
- Smallholders are often treated as risks in deforestation-free supply chains, writes Aida Greenbury, yet many are also among the people with the strongest reasons to keep forests standing.
- Greenbury argues that standards, traceability rules and buyer requirements can push costs onto farmers who lack the maps, documents, legal recognition and market access needed to comply.
- She says forest protection will work only if companies, donors, governments and NGOs make long-term commitments to smallholders, including support for land rights, incentives, better yields and trusted local institutions.

Indonesia’s nickel boom linked to rising illness and worker harm, reports find
- A newly published report by Indonesia’s human rights commission, Komnas HAM, includes new evidence of environmental and public health harms caused by the nickel mining industry in eastern Indonesia.
- Mongabay Indonesia has previously reported on increases in respiratory disease recorded by health workers in a community alongside the Indonesia Weda Bay Industrial Park in North Maluku province.
- The Komnas HAM human rights report also includes data showing high rates of respiratory disease around the Indonesia Morowali Industrial Park in Central Sulawesi province.
- A separate report published by a labor nonprofit focusing on interviews with workers showed many knew of colleagues who had died suddenly, while reports of suicide were common.

19,000 Great Pyramids a year: Report flags unsustainable rate of sand mining
- A new analysis of global sand extraction indicates the industry is removing roughly 50 billion metric tons a year, a pace that far outstrips natural replenishment.
- Experts say the loss of sand from landscapes, river deltas, and coastal zones threatens ecosystems, livelihoods and many processes on which life depends.
- Although the sand mining industry is operating at unsustainable levels, experts say measures exist to lessen its impact.
- Solutions include coordinated governance, stronger monitoring and long-term, cross-border planning.

Solar brings power to women entrepreneurs in Borneo, but rural energy inequality remains
- In the village of Muara Enggelam, East Kalimantan province, the arrival of affordable and reliable renewable energy has sparked a flurry of new businesses, some started by women who were previously unable to fulfil their economic ambitions.
- The remote village in Indonesian Borneo received its first installation of solar energy in 2015 following an allocation from Indonesia’s energy ministry.
- The electricity capacity remains limited, but households have been able to start small businesses selling food and drinks, while mobile internet has expanded market access via social media platforms.
- However, across the archipelago of 270 million people, the energy transition appears to have stalled in rural villages using solar, which a report authored by civil society organizations Celios and Greenpeace attributes largely to government fossil fuel subsidies.

At world’s largest shark conference, scientists warn of a grim outlook across the board
- Hundreds of researchers and conservationists met in Colombo from May 4-8 for Sharks International, held once every four years.
- Major topics at the conference included the trade in shark and ray meat, reducing shark bycatch, and the use of new technologies in conservation.
- Participants also highlighted innovative programs that encourage community-based conservation, and grappled with the contentious topic of closing fisheries to aid recovery of threatened species.

In eastern Indonesia, communities revive customary systems to protect the seas
- A new documentary, “Jejak Wallacea,” highlights how coastal communities across eastern Indonesia are reviving customary marine management systems to protect ecosystems threatened by destructive fishing, turtle hunting and habitat loss.
- Communities featured in the film use locally rooted approaches including seasonal fishing closures, turtle hatcheries, mangrove restoration, customary sanctions and community patrols to manage reefs, fisheries and coastal forests.
- Conservation groups behind the project say community-led systems rooted in Indigenous and local knowledge can succeed where top-down conservation models and formal protected areas alone often fall short.
- The initiatives have helped protect species including sea turtles, dugongs and thresher sharks, but organizers say long-term success depends on stronger government recognition and support for community-based conservation.

Wetland destruction blamed for rise in croc attacks on Indonesia’s Bangka Island
The destruction of coastal wetlands for illegal tin mining and oil palm plantations is to blame for a surge in crocodile attacks on people on Indonesia’s Bangka Island, residents say. Mongabay Indonesia contributor Taufik Wijaya reported that in February this year, a 40-year-old fisherman was killed by a saltwater crocodile (Crocodylus porosus) in the Menduk […]
New study explores how reforestation could help Java’s leopards survive
- A new study finds that strategically restoring degraded forests could help reconnect fragmented habitat for the endangered Javan leopard, giving the species more room to move across densely populated Java.
- Researchers created the first islandwide model of habitat connectivity for the species, showing how targeted reforestation could help offset some of the barriers created by roads, railways and urban development.
- Conservationists say isolated leopard populations face increasing risks from habitat loss, human conflict, disease and inbreeding, with only an estimated 320 Javan leopards remaining in the wild.
- Experts caution that the model still needs to be tested with real-world tracking data, but say reconnecting forests will be essential for the long-term survival of Java’s last apex predator.

Agriculture drives most tropical peatland loss in Indonesia, Peru and DRC: Study
Agriculture is the biggest driver of peatland loss in Indonesia, Peru and the Democratic Republic of Congo, home to the largest expanses of tropical peatlands in the world, a recent study has found. Peatlands are crucial in the fight against climate change: They cover less than 3% of the world’s landmass, but sequester more carbon […]
Paying people to see wildlife: Inside a $1-per-hectare conservation experiment in Borneo
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Stop telling people to protect wildlife. Start paying them instead. That’s the idea in a new experiment in Kapuas Hulu district, in Indonesia’s West Kalimantan province, which is testing whether conservation can be made to work with local […]
Indonesia should avoid controversial programs to fund conservation (commentary)
- Protecting nature is often a struggle due to funding gaps, which governments across developing countries are struggling to close.
- While officials may pursue plans to fund conservation with programs like carbon credits, as in the case of Way Kambas National Park in Indonesia, these may ironically impact critical habitats for threatened species.
- “Indonesia should not be overconfident that it can close the gap by using controversial programs,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Conservationists fear fires could erase years of orangutan habitat recovery
- Fires have burned part of a restoration site being prepared for orangutan habitat in Indonesia’s West Kalimantan province, raising fears that another severe fire season could undo years of recovery work.
- The restoration project, led by the government, Yayasan IAR Indonesia and local communities, has replanted about 300 hectares (740 acres) with 150,000 trees to help keep critically endangered orangutans out of nearby farms.
- Conservationists say the fires, likely sparked by nearby land clearing for oil palm, spread rapidly through dry peat and scrub vegetation, despite the area still being in the rainy season.
- With severe El Niño conditions forecast later this year, conservation groups warn they lack sufficient resources to fully prepare for another major fire season like the devastating 2015 crisis.

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.

A 10-year whale shark satellite study helps create new protected area in Indonesia
- Fishers and scientists joined together in Indonesia for a 10-year study to protect whale sharks (Rhincodon typus).
- The bagan fishers’ unique relationship with the endangered whale sharks enabled scientists to satellite tag the fish.
- The data from the decade-long study revealed previously unknown migration routes, feeding grounds and a whale shark nursery.
- The data will be used to help create a marine protected area designed for whale sharks.

International Leopard Day: A spotty outlook for the spotted cat
Leopards are the most widespread of the big cats, but their range across Asia and Africa is shrinking. In many places, so are their numbers. Recent Mongabay coverage of leopards (Panthera pardus) revealed a global trade in leopard trophies and body parts, but also more hopeful signs, such as leopards persisting on the edge of […]
In Indonesia, a schoolboy moves mountains on waste as government targets reform
- At just 12 years old, Syazwan Luftan Riady started a grassroots nonprofit of young people in East Java province focused on environmental protection.
- Now a second-year student at a prominent university in Indonesia, Luftan is also the protagonist of a children’s book and has received recognition from a U.S. organization for his campaigning work.
- The United Nations Environment Programme notes that Indonesia generates 3.2 million metric tons of plastic waste every year, the second most in the world after China.
- Indonesia’s president, Prabowo Subianto, announced in February a “war on waste” and is overseeing construction of 33 new electricity generation projects fueled by household waste. The president has also called for a volunteer army of schoolchildren to help clean up the country’s beaches and rivers.

Species thought extinct for thousands of years ‘rediscovered’ thanks to Indigenous knowledge
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. On a remote peninsula in Indonesian Papua, a species long thought extinct by scientists has been confirmed to survive. The evidence did not come from a formal survey. It began with conversations with Tambrauw elders, who described a […]
Tropical forest loss falls in 2025, but world still off track on deforestation goals
- Tropical primary forest loss fell sharply in 2025, down 36% from 2024, but the decline may reflect fewer fires rather than sustained progress.
- Despite the drop, the world still lost an area of tropical primary forest larger than Switzerland last year, leaving countries far off track from their 2030 goal of ending deforestation.
- Smaller forest-rich countries are losing remaining forests fastest, while major forest nations like Brazil show gains linked to stronger enforcement.
- Climate-driven fires, weak governance and commodity pressures continue to drive forest loss, making recent gains fragile and uncertain.

Indonesia escalates ‘war on waste’ with criminal probe into Jakarta landfill disaster
- On March 8, seven sanitation workers were killed at Southeast Asia’s largest landfill, the Bantargebang dump site east of Jakarta, Indonesia’s capital city.
- The country’s environment minister at the time, Hanif Faisol Nurofiq, told Mongabay that criminal charges against a former environment agency lead for the capital could be followed by charges against other civil servants.
- The criminal investigations into the former environment Jakarta and also in Bali were announced two months after President Prabowo Subianto announced a “war on waste” amid revived plans to build incinerators capable of turning millions of tons of household waste into electricity.

Deforestation is surging in Indonesia
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Indonesia’s forests, long held up as a case of tentative progress, are again under pressure. New analysis shows deforestation rose sharply in 2025, reversing several years of decline and returning to levels not seen in nearly a decade, […]
Investigators eye organized crime links in 3-ton pangolin scale haul at Jakarta port
- Customs officers in Jakarta planned to conduct interviews this month in connection with the seizure of more than 3 metric tons of pangolin scales, which inspectors found in a shipping container bound for Cambodia in late February.
- Mongabay Indonesia visited the address registered to the company exporting the container, but it appeared to be a shopfront, while its contact numbers registered in a government database were inactive.
- Indonesian authorities continue to make more pangolin scale seizures: This month, a Navy vessel intercepted a Vietnam-flagged cargo boat off the northwest coast of Java found to be carrying 780 kg (1,720 lbs) of scales.

Wetland destruction for mining, oil palm tied to crocodile attacks in Indonesia
- Bangka-Belitung, an island province located to the north of Sumatra Island, accounted for more than a quarter of the world’s tin production five years ago.
- Satellite analysis shows that this globally significant mining industry has come at extensive environmental cost: Bangka-Belitung lost 36% of its old-growth forest between 2002 and 2024, besides the deforestation incurred in the 20th century.
- In 2024, Indonesia’s Attorney General’s Office announced the country’s largest ever criminal corruption case, after investigators uncovered collusion with the state-owned tin miner, PT Timah, and illegal mining operators on Bangka.
- Meanwhile, local wildlife charities say deforestation of the coastal wetland on the west of Bangka Island, which was inhabited by humans at least as far back as the 7th century, may be to blame for the rise in human-wildlife conflicts afflicting local populations.

Fossil fuel subsidies and high costs stall energy transition across rural Indonesia
- Research by the Center of Economic and Law Studies (Celios) and Greenpeace shows the number of villages across Indonesia using solar energy among households declined by more than a quarter between 2021 and 2024.
- The authors of the Village Energy Transition Index said adoption of renewable energy in villages may reflect high installation costs and government subsidies for fossil fuels.
- Significant regional inequality exists between Java and other wealthier regions compared with the east of Indonesia, where solar potential energy is greater and where more rural communities would benefit from the technology.
- Anecdotal testimony indicates installations of basic photovoltaic systems often do not last long due to difficulties and costs associated with repairing units after a component fails, a particular challenge in coastal areas where salt corrosion is a factor.

EU deforestation law nudges timber trade, Indonesia probe shows, but risks persist
- An investigation tracing Indonesian timber to recently cleared forests shows EU-bound supply chains still carry deforestation risks, even as the bloc prepares to enforce stricter rules.
- The upcoming EU Deforestation Regulation (EUDR) is already shifting behavior, with some European buyers and Indonesian suppliers cutting ties and tightening traceability.
- But trade data from 2025 show high-risk imports continue, highlighting uneven progress and persistent loopholes in complex, opaque supply chains.
- Researchers and advocates say only full, consistent enforcement of the EUDR, alongside stronger due diligence and reforms in Indonesia, will meaningfully curb deforestation-linked timber trade.

See an orangutan, take a photo, earn some money: A viable conservation model?
- KehatiKu, a conservation program in Indonesian Borneo, pays citizen observers to document wildlife sightings and upload them via an app.
- Payments vary by species, with the highest rate, around $6, paid for verified orangutan sightings. Dedicated observers can make more than they would be paid at a full-time job.
- By paying citizen observers directly, the program aims to gather data on wildlife and incentivize conservation while spending much less than conventional conservation projects.
- The program has collected around 175,000 records in its first year of operations, but one expert notes that it has historically proven challenging to keep people engaged in long-term conservation initiatives.

Nearly a million birds shipped from Africa to Asia in 15 years; canaries top the list
- Hong Kong and Singapore, two Asian wildlife trade hubs, imported more than a million live wild birds, nearly two-thirds from Africa between 2006 and 2020, according to a new analysis of customs data. Canaries, including species declining in the wild, topped the list.
- More than two-thirds of the birds came from African countries where export regulations are weak, including Mali, Guinea, Tanzania and Mozambique.
- This massive live bird trade depletes wild populations and may spread dangerous diseases or invasive species, researchers say.
- Experts urge countries to restrict imports of live birds, implement stricter quarantine measures and adopt an approved list of pets that don’t pose risks to biodiversity or human health.

Indonesia braces for possible ‘Godzilla El Niño’ as fire season escalates early
- The 2026 fire season in Indonesia is already showing early signs of escalation, as burned areas reached 32,637 hectares by February, 20 times higher than the same period in 2025.
- Some global forecasts suggest this year’s predicted El Niño could become one of the strongest in at least a decade, raising the risk of prolonged drought and widespread fires, although significant uncertainty remains over how intense it will ultimately be.
- Fire monitoring by the watchdog Pantau Gambut show that many hotspots are in oil palm and timber concession areas, which the group says suggests that legal permits alone do not guarantee fire-safe land management and highlights gaps in oversight and enforcement.

‘Rediscovered’ species in Papua spotlight importance of Indigenous knowledge
- Two species of marsupial thought by scientists to be extinct for thousands of years still live in the forests of Indonesian Papua on the island of New Guinea, according to recently published research.
- One of the animals, the ring-tailed glider, is sacred to the Tambrauw people, and it’s part of a newly proposed genus, Tous, borrowing the Tambrauw name for the glider.
- The other animal, a pygmy long-fingered possum, was discovered during a mammal-watching trip on the Bird’s Head Peninsula.
- The research involved substantial collaborations with local communities and Indigenous elders.

Repeated failures expose gaps in Indonesia’s nickel waste management
- A deadly 2026 landslide in Indonesia’s Morowali nickel hub highlights risks in “dry stack” waste systems, which can still liquefy under poor conditions.
- Indonesia’s booming nickel industry generates massive volumes of toxic waste, with dry stack or “filtered” tailings promoted as safer than the typical wet sludge, but often poorly implemented.
- Experts cite design flaws, weak oversight, and challenging local conditions, including rainfall and seism activity, as key factors behind repeated failures.
- Watchdogs are calling for a halt to new tailings facilities and stronger safeguards, warning of ongoing risks to workers, communities and ecosystems.

The mother of orangutans
Dr Birutė Galdikas spent almost 50 years studying solitary and elusive orangutans in Borneo, at a time when no one believed it possible. Her pioneering work transformed scientific understanding of the great apes and their behavior. She passed on March 24 at the age of 79. Dr. Galdikas was one of three women who revolutionised […]
In Indonesia, a coastal vine used as medicine now signals ecological decline
- The beach morning glory (Ipomoea pes-caprae) vine is widely used as a traditional medicine in the north of Indonesia’s Sulawesi Island, and in many tropical coastal communities, to treat common complaints, and by fishers to treat stings from venomous fish.
- In addition to its medicinal use, the plant, also known as bayhops, reinforces beaches by binding sand dunes, increasing the resilience of global coastlines to risks of abrasion and erosion.
- Beach morning glory is a ubiquitous crawling vine, but some communities in Sulawesi’s Gorontalo province say the medicinal plant has disappeared locally due to industrial development and infrastructure construction.

Indonesia’s plan to rezone national park sparks backlash
Indonesia is moving to rezone Way Kambas National Park, transforming the Sumatran sanctuary from a “cost center” into a “profit center.” As Mongabay’s Hans Nicholas Jong reports, the government has framed the initiative as a carbon-trading and luxury-tourism initiative to fund conservation for ecosystem restoration. The proposed land reclassification would cut the park’s strictly protected […]
Indonesian geothermal projects stall amid Indigenous concerns over justice
An island in eastern Indonesia was meant to lead the country’s transition into renewable energy. But nearly a decade later, the “geothermal island” has suspended projects due to local resistance and concerns for justice and safety. Mongabay’s Basten Gokkon reports that, back in 2017, up to 21 geothermal sites were identified on the island of […]
Indonesia’s deforestation surges 66% in 2025, reversing years of decline
- New satellite data show that deforestation in Indonesia surged in 2025, up 66% from the previous year, marking a sharp reversal after several years of decline.
- The implications extend beyond forest loss, as rising deforestation could derail Indonesia’s climate goals, including its target of turning the forestry and land use sector into a net carbon sink by 2030.
- NGO Auriga Nusantara points to policy decisions under both the current and former administrations; at the same time, government-backed projects have been allowed to expand into forest areas, often without adequate spatial planning.

Oil surge sharpens calls for Indonesia to shift away from fossil fuels
- Indonesia faces rising fiscal and economic pressure as global oil prices surge amid the U.S.-Israel war on Iran, exposing its heavy reliance on imported fossil fuels.
- Analysts say the crisis underscores the need to accelerate renewable energy development, which could reduce exposure to volatile global markets and improve long-term economic stability.
- Despite this, the government is also boosting coal output and exploring expanded biofuel use — moves that critics warn could undermine climate goals and create new environmental risks.
- Civil society groups are calling for windfall taxes on fossil fuel companies to fund a just energy transition, arguing current policies risk deepening inequality and dependence on extractive industries.

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.

US-Indonesia trade deal slammed as ‘extractive colonialism’ over mining, fossil fuels
- Activists warn a new U.S.-Indonesia trade deal could accelerate mining, deforestation and fossil fuel use, with weak, nonbinding environmental safeguards.
- The agreement prioritizes critical minerals and energy access, opening up Indonesia’s resource sectors to deeper U.S. investment while limiting state control.
- Expanded nickel mining and coal-powered processing risk worsening pollution, land conflicts and forest loss, especially in already affected regions like Sulawesi and the Malukus.
- Large fossil fuel import commitments could undermine Indonesia’s climate goals, highlighting contradictions in the global energy transition and raising concerns for Indigenous and local communities.

Birutė Galdikas, primatologist who spent a lifetime studying & defending orangutans, has died at 79
- Birutė Galdikas established one of the longest-running field studies of any wild mammal, helping to transform scientific understanding of orangutans and their behavior.
- Her work combined research with hands-on rehabilitation, returning hundreds of orangutans to the wild while navigating debates over the role of intervention in field science.
- As Borneo’s forests declined, she expanded her efforts into conservation, founding an organization and working with local communities to protect habitat under growing economic pressure.
- As part of the “Trimates”, a group of female researchers recruited by Louis Leakey, she helped bring great apes into public view and frame orangutans as emblematic of broader environmental loss.

Palm oil clearing advances in Bornean orangutan habitat despite red flags
- A palm oil firm has cleared more than 3,000 hectares (7,500 acres) of forest inside a UNESCO biosphere reserve in Indonesian Borneo, threatening areas identified as orangutan habitat.
- The concession overlaps with a wildlife corridor linking two national parks, raising concerns over habitat fragmentation and increased human-orangutan conflict.
- Authorities have acknowledged the presence of the habitat inside the company’s concession, but proposed voluntary conservation measures rather than halting clearing, drawing criticism from environmental groups.
- The case highlights broader issues of weak enforcement, disputed land rights with Indigenous communities, and supply-chain loopholes that continue to allow deforestation-linked palm oil into global markets.

The ocean’s enforcement gap
- Governments have designated vast marine protected areas and pledged to conserve 30% of the ocean by 2030, enforcement often lags behind these commitments.
- Research shows that the ecological benefits of marine protected areas depend less on their size than on whether rules are visible, monitored, and enforced.
- New tools—such as satellite imagery, vessel-tracking systems, and data analytics—are making it easier and cheaper to detect illegal fishing and focus enforcement efforts.
- As monitoring improves, the future of ocean conservation may depend less on creating new protected areas than on ensuring existing rules are consistently applied.

Songbird trade threatens lesser-known ‘master birds’ with secondary extinctions: Study
- Master birds are used in songbird competitions in Southeast Asia and other parts of the world to “teach” competitors elements of their songs. This trade, largely unknown and under-researched, is pushing some species to the brink of extinction.
- A recent market study investigated the trade in crested jayshrikes, a popular master bird in Indonesia, and discovered rampant trade: This bird was sold openly across the country, despite its protected species status.
- The trade in master birds has driven serious declines of numerous species in the wild, including the Javan green magpie.
- To save these rapidly disappearing birds, the researchers say that stricter law enforcement is urgently needed to shut down illegal markets and stem the trade.

Deadly Indonesia landfill collapse a ‘serious warning’ of systemic failure
A mountain of waste at Indonesia’s largest landfill recently collapsed following days of extreme rainfall that destabilized the massive pile. The tragedy resulted in seven confirmed deaths.
Jakarta port authorities seize 3 tons of pangolin scales in Cambodia-bound container
- A spot inspection of a 20-foot container by customs authorities at Indonesia’s largest port in late February uncovered more than $10 million in pangolin scales.
- There are eight species of the herbivorous pangolin, all categorized as threatened due to habitat loss and poaching, which is largely to supply raw material for Chinese traditional medicine, despite the total absence of any scientific proof of medicinal benefit.
- Indonesia’s Ministry of Forestry and the Bogor Institute of Agriculture, Indonesia’s premier forestry faculty, estimate that every kilogram of pangolin scales requires the death of up to five pangolins.
- Separately, a police officer convicted last year over a scheme to trade 1.2 metric tons of pangolin scales stolen from a police evidence room had his nine-year sentence reduced to seven on appeal.

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.

Facebook shuts Indonesia groups after Mongabay and Bellingcat report illegal wildlife trade
- Facebook parent company Meta has closed nine groups on the social network after reporters from Mongabay and Bellingcat found evidence of illegal wildlife trade being conducted openly on the platform in Indonesia.
- In one Facebook group, reporters last year found an advertisement for a rhinoceros hornbill (Buceros rhinoceros), a protected species.
- “Bad actors constantly evolve their tactics to avoid enforcement, which is why we partner with groups like the World Wildlife Fund and invest in tools and technology to detect and remove violating content,” Meta said in a statement.

Indonesia plan to rezone elephant reserve for carbon trading and tourism sparks backlash
- Indonesia plans to rezone large parts of Way Kambas National Park in Sumatra for carbon trading and luxury tourism to raise conservation funds.
- Critics warn the move could fragment core habitat and harm critically endangered species like Sumatran elephants, tigers and rhinos.
- Experts say carbon projects and reforestation could reduce elephant food sources and worsen human-wildlife conflict.
- Concerns are mounting over transparency, governance and whether revenues will truly support conservation and local communities.

An ancient fishing tradition in Indonesia could help build a more sustainable fishery
In the remote coastal areas of eastern Indonesia, a centuries-old tradition is providing a contemporary blueprint for sustainable development. The practice, known as Sasi Laut, imposes temporary fishing closures of six to 12 months to allow sedentary marine species such as sea cucumbers and shellfish to replenish. A new study published in Marine Policy reveals […]
Mass pilot whale stranding in Indonesia raises questions about ocean health
Villagers in central Indonesia rescued 34 short-finned pilot whales following a mass stranding on March 9, but despite their overnight efforts were unable to save 21 others. Mongabay Indonesia’s Ebed De Rosary reports that residents first discovered the pod in the shallow waters off Deranitan village, in East Nusa Tenggara province, at approximately 3:30 p.m. […]
Indonesia’s orangutan trafficking cases reveal need for a change in approach (commentary)
- Indonesia needs a new approach to illegal wildlife trafficking that does more than intercept and repatriate animals to their home habitats, a new op-ed suggests.
- Seizures of trafficked orangutans have been in the news often lately, and the nation needs to make trafficking of animals such as these unprofitable, unviable and socially unacceptable.
- “Repatriation brings (trafficking) victims home, but it should never become a routine that normalizes the crime. If a country celebrates each return while shipments keep moving through the next gap, it is responding, never preventing,” he argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Sumatra officials stress environment checks continue in wake of deadly cyclone
- More than three months after flash flooding caused by the landfall of Cyclone Senyar over Sumatra killed more than 1,000 people in three provinces, officials continue to face pressure to review companies operating in forests and watersheds.
- In West Sumatra province, environmental officials point to sanctions issued against quarries operating near Mount Sariak, a short distance to the north of Padang, the provincial capital.
- However, West Sumatra is a mountainous province larger than Switzerland, with many extractive areas operating in forests that can take inspectors at least a day to reach from the provincial capital.
- At least 267 people were killed in West Sumatra, with 70 people still missing at the time of writing, after Cyclone Senyar struck on Nov. 26 and 27.
