Indonesia closes 2025 with rising disasters and stalled environmental reform
- Deadly floods and landslides in Sumatra in late 2025 underscored how deforestation, weak spatial planning and extractive development have increased Indonesia’s vulnerability to extreme weather — problems scientists and activists say the government has largely failed to confront.
- Forest loss surged nationwide in 2025, with Sumatra overtaking Borneo as the main deforestation hotspot, while large areas of forest in Papua were redesignated for food estates, agriculture and biofuel projects, raising concerns over carbon emissions and biodiversity loss.
- Despite international pledges to phase out coal, national energy plans continued to lock in coal, gas and biomass co-firing for decades, while palm oil expansion and mining — including in sensitive areas like Raja Ampat — remained central to development strategy, often prompting action only after public pressure.
- Civil society groups increasingly turned to lawsuits amid shrinking space for dissent, rising criminalization of Indigenous communities and activists, and growing militarization of land-use projects — trends campaigners warn are weakening democratic safeguards and environmental protections alike.

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.

The year in rainforests 2025: Deforestation fell; the risks did not
- This analysis explores key storylines, examining the political, environmental, and economic dynamics shaping tropical rainforests in 2025, with attention to how policy, markets, and climate stress increasingly interact rather than operate in isolation.
- Across major forest regions, deforestation slowed in some places but degradation, fire, conflict, and legacy damage continued to erode forest health, often in ways that standard metrics fail to capture.
- Global responses remained uneven: conservation finance shifted toward fiscal and market-based tools, climate diplomacy deferred hard decisions, and enforcement outcomes depended heavily on institutional capacity and credibility rather than formal commitments alone.
- Taken together, the year showed that forest outcomes now hinge less on single interventions than on whether governments and institutions can sustain continuity—of funding, governance, science, and oversight—under mounting environmental and political strain.

Photos: Tourism ambitions clash with local livelihoods on Indonesia’s Lombok Island
- Residents of Tanjung Aan Beach on the Indonesian island of Lombok say they were evicted with little notice or compensation as the Mandalika tourism project advances, leaving many without livelihoods or alternatives.
- The government-controlled developer has defended its process, citing compensation paid in a different land zone, but locals say support didn’t reach the coastal community now being cleared.
- Perspectives diverge sharply: locals describe loss, fear and declining income, while some foreigners and investors argue the development is legal, overdue and ultimately beneficial.
- Younger Lombok residents highlight deeper systemic issues — weak regulation, rising costs and limited opportunities — saying tourism growth increasingly serves visitors, not locals.

Taboo against harming strangler fig spirits protects forests in Indonesian Borneo
- The Iban community in West Kalimantan, Indonesian Borneo, says it believes large strangler fig trees are inhabited by dangerous spirits, leading community members to protect these trees from harm wherever they occur.
- When clearing land for farming, the community protects the fig tree as well as islands of vegetation around the tree, which together account for 1-2% of their farmland dedicated to protecting the strangler figs.
- Research published in Biotropica found that strangler figs are equally or more abundant in the community’s farmland compared with old-growth, with 25 species identified across the landscape.
- These protected fig trees and surrounding vegetation serve as crucial refuges and stepping stones for wildlife, demonstrating how traditional spiritual beliefs can have measurable biodiversity benefits that could be replicated elsewhere.

Bethany “Bee” Smith, researcher who documented a megamouth shark alive, died in a diving accident, aged 24
- Bethany “Bee” Smith was part of a generation of scientists who worked in the field while also explaining their work publicly, narrowing the distance between research and spectacle without denying the risks that came with it.
- Trained as a marine biologist, she spent years studying sharks, working with fishing communities and researchers, and focusing on conservation problems where trust and policy mattered as much as data.
- After years of preparation and failed attempts, she achieved a rare feat: documenting a live megamouth shark, one of the least understood large animals on Earth, in work focused on evidence rather than thrill.
- She died at 24 during a freediving accident in Indonesia while working on a shark conservation project, after reaching a goal that had occupied years of careful effort and preparation.

A flood of logs post-Cyclone Senyar leaves Padang fishers out of work
- Flash floods in late November swept timber and mud from upstream forests into coastal waters around Padang, blocking access to the sea and cutting off the livelihoods of hundreds of fishers.
- Fishers say massive floating logs have damaged boats and halted daily incomes, forcing many families to rely on credit to meet basic needs.
- Marine scientists warn that suspended sediment and decaying timber threaten coastal ecosystems by blocking sunlight, disrupting food chains and degrading water quality.
- Environmental groups link the disaster to illegal logging and weak forest governance upstream, calling for stronger law enforcement, national disaster status and urgent government action.

Rethinking how we talk about conservation—and why it matters
- Feedback from across the conservation sector suggests a shift in how the movement talks about itself—from crisis-heavy messaging toward agency and evidence—because constant alarm fatigues audiences while stories of progress keep them engaged.
- Respondents to date have emphasized that scalable, durable conservation efforts share core traits: genuine local leadership, transparency about what works (and what doesn’t), visible community benefits, and diversified funding that strengthens resilience.
- Practitioners highlighted the importance of aligning human well-being with environmental outcomes, with models like Health in Harmony showing how rights, livelihoods, and conservation can reinforce one another when communities define their own priorities.
- This piece builds on a conversation Mongabay founder and CEO Rhett Ayers Butler had last week at the Emerging Wildlife Conservation Leaders (EWCL) conference in Washington, D.C.

Pulp giant RGE admits possible deforestation breach in Bornean wildlife habitat
- A new report links forestry giant Royal Golden Eagle’s pulp supply chain to the clearance of 5,565 hectares (13,751 acres) of natural forest in Indonesian Borneo between 2020 and 2024, despite the company’s no-deforestation pledge. RGE says the clearing was likely non-compliant.
- The deforestation occurred in the Mahakam River watershed, one of Indonesia’s last intact rainforest regions and habitat for critically endangered species including Bornean orangutans, Irrawaddy dolphins and Sumatran rhinos.
- Timber from two Bornean concessions flowed through a single wood chip mill to RGE’s Asia Symbol pulp plant in China. The mill had already been linked to earlier deforestation breaches.
- The case may undermine RGE’s effort to regain certification under the Forest Stewardship Council (FSC), and has also renewed scrutiny of banks financing the group, with campaigners urging suspensions until deforestation across its supply chain stops.

Tsunami veteran rescue elephants mobilized for Indonesia cyclone disaster relief
- The number of people killed by flash floods after Cyclone Senyar made landfall over Sumatra on Nov. 26 increased to 1,059 on Dec. 18. In Pidie Jaya district, on the north coast of the semi-autonomous region of Aceh, officials assigned a team of four rescue elephants, veterans of the recovery operation after the 2004 Boxing Day tsunami that killed more than 200,000 people in Aceh.
- The Aceh conservation agency said the elephants were uniquely able to help remove fields of logs carried down valleys by the worst flash floods to hit the region in years, with the scale of debris fields impassable to heavy machinery.
- “They are trained and experienced elephants,” the head of Aceh’s conservation agency told Mongabay, while emphasizing that officials went to great lengths to ensure the Sumatran animals’ welfare.
- At least one Sumatran elephant was presumed killed in flash floods caused by Cyclone Senyar, after residents in a village neighboring the rescue elephants’ workplace discovered the animal’s body Nov. 29.

Tapanuli orangutan, devastated by cyclone, now faces habitat loss under zoning plans
- A proposed zoning overhaul in Indonesia’s North Sumatra province could strip legal protections from nearly a third of the Batang Toru ecosystem, threatening the last remaining habitat of the critically endangered Tapanuli orangutan.
- The proposal came just before a powerful cyclone triggered floods and landslides that may have killed or displaced dozens of Tapanuli orangutans and severely damaged thousands of hectares of forest.
- The changes would weaken scrutiny of mining and plantation projects, including a planned expansion of a nearby gold mine, by removing the area’s “provincial strategic” designation.
- Conservationists say rolling back protections now would be a “nail in the coffin” for the species, calling for emergency protections and expanded conservation measures to prevent population collapse.

Orangutans rescued from the wildlife trade undergo intensive re-training to return to the wild
NORTH SUMATRA, Indonesia — Welcome to jungle school, where orphaned orangutans are learning the basics for survival that they will need for life in the wild. At the Orangutan Information Centre (OIC) in North Sumatra, vets and biologists are rehabilitating orangutans who have been confiscated from the illegal wildlife trade. Once they have mastered the […]
Indonesia’s 1st Javan rhino translocation ends in death, in conservation setback
- Indonesia’s first effort to translocate a Javan rhino ended in loss when Musofa died days after his move to a protected facility in Ujung Kulon National Park.
- Officials said a necropsy found long-standing health problems linked to severe parasitic infection, though questions remain about the sudden decline linked to the relocation.
- Conservationists say the setback should not stop efforts to save the species, which faces serious risks from low numbers and limited genetic diversity.

Green labeler PEFC under fire for certifying Indonesian firm clearing orangutan habitat
- Sustainable forestry certifier PEFC is under fire for its endorsement of Indonesian plantation firm IFP despite it being a major recent deforester, with tens of thousands of hectares cleared in orangutan habitat and ongoing forest loss documented into 2024.
- Earthsight and other NGOs say the certification exploits loopholes, including PEFC’s “partial certification” model that lets companies exclude recently cleared areas while still selling certified timber.
- Deforestation-linked timber may have entered global supply chains, with mills processing IFP-linked wood exporting large volumes to the EU ahead of the bloc’s new deforestation regulation.
- Critics say PEFC’s weak safeguards and Indonesia’s IFCC certification system enable greenwashing, and call for IFP’s certification to be revoked and rules tightened to bar any company or corporate group involved in post-2010 forest clearing.

Sumatra’s ‘natural’ disaster wasn’t natural: How deforestation turned a rare cyclone catastrophic
- Cyclone Senyar was an unusually rare event for Sumatra, but the scale of destruction cannot be explained by weather alone. Decades of deforestation, mining, plantations, and peat drainage left watersheds unable to absorb intense rainfall, turning extreme weather into a mass-casualty disaster.
- Forest loss and land conversion have systematically weakened Sumatra’s natural defenses. The island has lost millions of hectares of forest since 2001, increasing runoff, destabilizing slopes, and amplifying floods and landslides when heavy rain hits.
- Peatland drainage has created a hidden, compounding flood risk. Canals dug for plantations dry and compact peat soils, causing land subsidence and transforming once water-retentive landscapes into low-lying areas prone to chronic inland and coastal flooding.
- Rising exposure, not just rising hazards, is driving future risk. Urban expansion into floodplains and degraded catchments means that even rare storms now endanger more people and infrastructure, locking much of Sumatra into a cycle of disaster unless land-use governance changes.

Sumatran flood disaster may have wiped out a key Tapanuli orangutan population, scientists fear
- As many as 35 critically endangered Tapanuli orangutans — 4% of the species’ total population — may have been wiped out in the catastrophic floods and landslides that struck the Indonesian island of Sumatra recently, scientists warn, after the discovery of a carcass.
- Satellite and field evidence show massive destruction of the western block of the Batang Toru ecosystem, with thousands of hectares of steep forest slopes destroyed — an “extinction-level disturbance” for the world’s rarest great ape.
- Conservationists have lost contact with monitored orangutans in the disaster zone, raising fears more individuals were killed or displaced as feeding areas and valleys were obliterated.
- The tragedy has renewed calls to safeguard the Batang Toru ecosystem by halting industrial projects and granting it stronger protection, as climate-driven disasters escalate across Sumatra.

Boom in burning waste for fuel could put human health and environment at risk
- Refuse-derived fuel (RDF) — conglomerated waste often composed of up to 50% plastic — is being burned globally in waste-to-energy incinerators, cement kilns, paper mills, and by other industries.
- Proponents say RDF reduces fossil fuel use and produces cleaner energy, while diverting waste from landfills.
- Critics say a lack of monitoring often hides RDF’s true environmental and human health footprint, and that when burned alongside fossil fuels, the technology can significantly worsen pollution. Health issues potentially connected to RDF contaminants range from cancer to hormone disruption.
- That’s a major concern as RDF ramps up, with countries in the Global South especially starting to use and dispose of waste in this way. Burning RDF and the incineration of plastic waste has been linked to greenhouse gas emissions and also extremely toxic pollutants such as dioxins.

Death toll rises in Sumatra flood catastrophe as gov’t moves to protect Batang Toru forest
- The number confirmed killed following the most fatal flooding to hit the Indonesian island of Sumatra for decades increased to almost 1,000 on Dec. 9.
- On Dec. 6, Indonesia’s Environment Minister Hanif Faisol Nurofiq suspended companies operating in the badly affected Batang Toru ecosystem, an old-growth Sumatran rainforest home to the Tapanauli orangutan (Pongo tapanuliensis), the world’s most endangered species of ape.
- The chief executive of Mighty Earth praised the move, saying reducing deforestation was critical to avoiding a repeat of the disaster.
- In the week beginning Dec. 8, first responders in three provinces continued work in challenging terrain to recover the dead and rescue the injured two weeks after a rare cyclone, named Senyar, made landfall over Indonesia’s largest island.

Rescue teams racing after last week’s flooding in Indonesia, Sri Lanka and Thailand
BATANG TORU, Indonesia (AP) — Rescue teams raced Wednesday to reach communities isolated by last week’s catastrophic floods and landslides in Indonesia, Sri Lanka and Thailand as over 800 people remained missing and economic damage became more clear. Over 1,400 were killed: at least 770 in Indonesia, 465 in Sri Lanka and 185 in Thailand, with three […]
Indigenous Dayak sound alarm as palm oil firm razes orangutan habitat in Borneo
- Indigenous Dayak communities report wildlife encroaching into villages, land grabbing, and loss of cultural and livelihood resources as a palm oil company begins clearing forests on their customary lands — in some cases without consent or even prior notification.
- PT Equator Sumber Rezeki (ESR) has already cleared nearly 1,500 hectares (3,700 hectares) of rainforest inside this region that’s designated a UNESCO Biosphere Reserve and orangutan habitat, with much of the deforestation occurring this year and signaling far more destruction to come.
- The company’s parent group, First Borneo, is driving widespread deforestation across Kapuas Hulu with two other plantations, yet its palm fruit is still entering global “zero-deforestation” supply chains through intermediary mills despite corporate no-buy pledges.
- Environmental groups are urging the government to halt or revoke ESR’s permits and protect the orangutan-rich landscape, warning that continued clearing undermines Indonesia’s climate commitments and threatens both biodiversity and cultural survival.

As agroforestry declines in Indonesia’s Flores, a traditional ecological lexicon fades with it
- In Indonesia’s Flores highlands, the Manggarai people once practiced diverse agroforestry that blended farming with forest care — traditions carried in hundreds of specialized words for crops, tools and rituals.
- A new study recorded 253 of these agroforestry terms now at risk of disappearing as monoculture farming, tourism and forest loss reshape Manggarai’s landscapes and livelihoods.
- From 2002 to 2024, Manggarai lost about 71 hectares (175 acres) of humid primary forest, mostly cleared for monoculture plantations that disrupt traditional agroforestry systems.
- Researchers say reviving the fading lexicon — through schools, community exchanges and policy support — can help restore Indigenous knowledge crucial for biodiversity, food security and climate resilience.

Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Off the western coast of Sumatra, Indonesia, the Mentawai Islands rise from the Indian Ocean in a patchwork of forests and rivers where macaques, gibbons and hornbills thrive. Among the Indigenous Mentawai, an ancient cosmology called Arat Sabulungan […]
Saving forests won’t be enough if fossil fuels beneath them are still extracted, experts warn
- A new analysis finds that tropical forests in 68 countries sit atop fossil fuel deposits that, if extracted, would emit 317 billion metric tons of greenhouse gases — more than the remaining 1.5°C (2.7°F) carbon budget — revealing a major blind spot in global climate policy.
- Because Brazil’s proposed Tropical Forest Forever Facility (TFFF) focuses only on stopping deforestation, researchers warn it risks missing far larger emissions from potential oil, gas and coal extraction under protected forests.
- India, China and Indonesia hold the largest fossil reserves beneath forests, with Indonesia facing acute trade-offs as most of its coal lies under forest areas where mining threatens biodiversity and Indigenous communities, including rhino habitats in Borneo.
- Experts say that compensating countries for leaving fossil fuels unextracted — through mechanisms like debt swaps or climate finance — could unlock massive climate benefits, but fossil fuel phaseout remains excluded from TFFF negotiations despite growing calls to include it.

Already disappearing, Southeast Asia’s striped rabbits now caught in global pet trade
- Rare, elusive and little-known to science, two species of striped rabbits are endemic to Southeast Asia: Sumatran striped rabbits from Indonesia and endangered Annamite striped rabbits from the Vietnam-Laos border region.
- Both species are threatened by habitat loss and illegal snaring, despite having protected status in their range countries.
- In recent months, authorities have seized at least 10 live rabbits smuggled from Thailand on commercial flights to India, highlighting the first known instance of these rabbits being trafficked internationally for the pet trade.
- Conservationists say this trend is alarming, given that the two species are on the brink of extinction. They urge range countries to add the two species to CITES Appendix III, the international wildlife trade convention, and to work with Thai authorities to establish a conservation breeding program with the seized rabbits.

Bearing witness to Indonesia’s environmental challenges: Sapariah Saturi
- Sapariah “Arie” Saturi grew up in West Kalimantan amid recurring forest and peatland fires, experiences that shaped her understanding of Indonesia’s environmental crises.
- After beginning her journalism career in Pontianak in the late 1990s, she joined Mongabay Indonesia at its inception and helped build it into a national environmental newsroom.
- As managing editor, she oversees a dispersed team of more than 50 reporters, beginning her days before dawn to edit stories, coordinate coverage, and guide investigations across the archipelago.
- Her commitment is grounded in independence, empathy, and the belief that environmental journalism can help communities, influence policy, and deepen public understanding of Indonesia’s overlapping crises.

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.

With military backing and oligarch allies, Indonesia pushes controversial food estate
- The Indonesian government is fast-tracking a massive food estate and biofuel push in South Papua, anchored by new plantations, an $8 billion bioethanol supply chain, and major infrastructure projects including a new highway and expanded airport plans.
- The initiative revives decades of state-driven “food estate” ambitions that have repeatedly failed — from Suharto’s peat-wrecking Mega Rice Project to Joko Widodo’s abandoned cassava fields — yet now comes with stronger political will, military backing, and efforts to attract private and international partners, including Brazil.
- Funding and execution remain shaky, with the appointed operator, PT Agrinas Pangan Nusantara, still unfunded amid competing fiscal pressures as the government pursues costly programs like nationwide free school meals.
- Large-scale land clearing is already underway amid reports of militarized suppression of local resistance, while oligarch allies such as the Jhonlin Group are playing prominent roles, underscoring both the urgency and controversy surrounding Prabowo’s self-sufficiency drive.

Indigenous Dayak resist new southern Borneo national park amid global protection deficit
- Indigenous peoples and student protesters staged several demonstrations in Indonesian Borneo in August in a bid to pressure local authorities to cancel plans for a 119,779-hectare (295,980-acre) national park in the Meratus mountain range.
- Meratus Mountains National Park would be the first national park in South Kalimantan province, and the 58th in Indonesia.
- The draft plans will absorb almost two dozen villages impacting several thousand families, many of whom fear displacement given the lack of formal state recognition of Indigenous communities.
- Local civil society organizations say the public protests reflect a lack of consultation with affected communities, a pattern established by many governments as countries rush to protect 30% of the world’s land and marine areas by 2030.

How Indonesian communities rescued the Bali starling from the brink of extinction
One of the world’s rarest birds has rebounded from near extinction after Indigenous communities on the Indonesian island of Bali committed to protect it under traditional laws, Mongabay contributor Heather Physioc reported. The Bali starling (Leucopsar rothschildi) is a songbird with striking white plumage and a cobalt-blue face. In 2001, just six birds were known […]
Study maps whale shark stranding hotspots in Indonesia, highlights conservation needs
- A new study has identified whale shark stranding hotspots in Indonesia and linked them to seasonal ocean conditions, offering scientists a clearer picture of when and where risks are highest.
- The researchers found that most strandings involved juveniles and often occurred during upwelling seasons; they highlighted that human pressures such as fishing gear, ship traffic and pollution may further increase the danger.
- The study calls for stronger rescue networks, better community training, and international cooperation to improve survival rates and protect these migratory animals across the region.

Indonesia labeled ‘Fossil of the Day’ for echoing industry talking points at COP30
- Indonesia has been publicly rebuked at COP30 with a “Fossil of the Day” award after civil society groups accused its delegation of echoing fossil fuel and carbon industry lobbyists during negotiations on Article 6.4, the U.N.’s new carbon market mechanism.
- Observers say Indonesia’s position closely mirrors the talking points in an industry-backed letter calling for weaker safeguards under Article 6.4 — a move critics warn could undermine the integrity of global carbon markets and benefit groups with financial stakes in nature-based carbon projects.
- Indonesia denies being influenced by lobbyists, even though at least 46 representatives from fossil fuel and heavy-industry companies are accredited under its delegation — raising broader concerns about corporate access to negotiations amid a COP already flooded with a record proportion of fossil fuel lobbyists.
- Experts warn Indonesia’s push to loosen Article 6.4 rules risks weakening international oversight, aligning the mechanism with the far less transparent Article 6.2, and potentially undermining both Indonesia’s climate credibility and the robustness of the Paris Agreement’s carbon market safeguards.

But a new group has been found — in a peat swamp about 32 km (20 mi) away. In October last […]
As Indonesia turns COP30 into carbon market showcase, critics warn of ‘hot air’
- Indonesia is using the COP30 climate summit to aggressively market its carbon credits, launching daily “Sellers Meet Buyers” sessions and seeking international commitments 6 despite unresolved integrity issues in its carbon market.
- Experts warn Indonesia’s credits risk being “hot air,” since its climate targets are rated “critically insufficient,” meaning many claimed reductions may not be real, additional or permanent — especially in forest-based projects.
- Forest and land-use credits, Indonesia’s biggest selling point, are among the riskiest, with high risks of overcrediting, leakage and nonpermanence; ongoing fires and deforestation further undermine credibility.
- Environmental groups say the carbon push distracts Indonesia from securing real climate finance, enabling wealthy nations to offset rather than cut emissions, while leaving Indonesia vulnerable to climate impacts and dependent on a fragile market.

Gibbon trafficking pushes rehabilitation centers to the max in North Sumatra
- Famed for their free-flow swinging through the forest canopy, gibbons are being relentlessly shot, stolen and incarcerated to supply an escalating illegal pet trade that targets babies in particular.
- Experts point to misleading social media content and a surge in private zoo collections as fueling the trade. Hundreds of the small apes have been confiscated by authorities across South and Southeast Asia in the past decade, with India and the UAE emerging as primary destinations.
- Gibbon rehabilitation centers, mostly operated by NGOs struggling for funding, are buckling under the numbers of animals in need of rescue and care.
- The trade imposes overwhelming suffering on the trafficked animals and immense wastage among the complex social groups gibbons live in, driving already threatened species ever closer to extinction.

To fix the climate, simply empower Indigenous people (commentary)
- While nations search for complex climate solutions at this year’s COP30 climate meeting in Belém, a simple yet powerful answer is just waiting in the wings: empowering the world’s most powerful protectors of forests and nature – Indigenous people – and we must let them point the way, a new op-ed argues.
- Ending fossil fuel use and transforming global food systems are essential but expensive and take time, but nations like Indonesia can score an immediate climate win by enacting its long debated Indigenous Peoples Bill, for example.
- “Humanity seeks an answer, but the answer has always been here,” the Sira Declaration states. “The answer is us.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Rise in Chinese off-grid coal plants in Indonesia belies pledge to end fossil fuel support
- Chinese president Xi Jinping has pledged to end the country’s financing of overseas coal projects — but a surge in Chinese-backed coal-fired power plants to supply electricity to nickel mining and processing undermines that pledge.
- Chinese investment has been flowing into Indonesia’s metal mining and smelting sector in a bid to supply raw materials to electric vehicle battery makers amid a transition to the zero-emission vehicles.
- By the end of the decade, about 44% of processed nickel for use in batteries and also for stainless steel will come from Indonesia.

Asian golden cat range expands, but declines continue amid rising threats
- The Asian golden cat (Catopuma temminckii) is a medium-sized cat species that was once abundant across Asia, ranging from India to China. Today its population is undergoing a significant decline.
- That’s resulted in it now being declared a threatened species as its habitat is lost or fragmented, and indiscriminate snaring removes it from forests, particularly in Southeast Asia.
- Targeted research, conservation and funding are rare for this species, resulting in significant knowledge gaps about its basic ecology and threats. That uncertainty is causing some conservationists to say it could warrant endangered status.
- It’s hoped that increasing threat levels imperiling the Asian golden cat will spur donor funding, giving researchers the tools to shine a light on the needs of this lesser-known felid. Nepal has so far led the way in conservation efforts.

New pledge, old problems as Indonesia’s latest Indigenous forest promise draws skepticism
- Indonesia has pledged to recognize 1.4 million hectares (3.5 million acres) of Indigenous and customary forests by 2029, a move the government says will curb deforestation and advance Indigenous rights.
- Advocates call the pledge another empty promise, citing years of stalled reforms, including a long-delayed Indigenous Rights Bill and a slow, bureaucratic process that has recognized less than 2% of mapped customary forests.
- Rights groups say state-backed development continues to drive land grabs and forest loss, with a quarter of Indigenous territories overlapping extractive concessions and widespread conflicts linked to the government’s strategic national projects (PSN).
- Critics urge the government to enact legal reforms and recognize Indigenous land beyond the 1.4-million-hectare target, warning that without real action, the pledge will be symbolic rather than transformative.

Scientists call for stronger action to save Indonesia’s vanishing seagrass meadows
- Marine experts at the Indonesian Seagrass Symposium in Bali warned that seagrass ecosystems — vital for carbon storage, biodiversity and coastal protection — remain largely overlooked in national policy and conservation efforts.
- Seagrass coverage in Indonesia has fallen from around 30,000 km2 in 1994 to about 8,000 km2 today, with losses driven by pollution, mining, coastal development and sedimentation that reduces water clarity and habitat quality.
- Indonesia holds some of the world’s most extensive remaining seagrass meadows, estimated to store more than 30 million metric tons of CO2, making their protection crucial for both national and global climate goals.
- Scientists and conservation leaders urged stronger data collection, funding and institutional capacity to support restoration, monitoring and community participation, positioning Indonesia as a potential leader in seagrass conservation.

Indonesia pledges energy transition — but the country’s new NDC says otherwise
- Indonesia’s newly submitted second nationally determined contribution (SNDC), in accordance with the Paris Agreement, contains emission-reduction targets widely seen as insufficient to meet the goal of limiting warming to 1.5° Celsius.
- This contrasts with President Prabowo Subianto’s pledges to achieve 100% renewable energy by 2035 and to phase out coal within 15 years, raising hopes that Indonesia could embark on a genuine energy transition.
- Under the SNDC’s high-growth scenario of 8% annual economic growth, Indonesia’s emissions are projected to be roughly 30% higher in 2035 than in 2019; in contrast, a 1.5°C-compatible pathway would require a 21% reduction.
- Critics say this suggests deep climate action is still seen as incompatible with rapid economic growth.

Report urges full protection of world’s 196 uncontacted Indigenous peoples
- A comprehensive global report on uncontacted Indigenous peoples, published Oct. 27 by Survival International, estimates that the world still holds at least 196 uncontacted peoples living in 10 countries in South America, Asia and the Pacific region.
- About 95% of uncontacted peoples and groups live in the Amazon — especially in Brazil, home to 124 groups. Survival International says that, unless governments and private companies act, half of the groups could be wiped out within 10 years.
- Nine out of 10 of these Indigenous groups face the threat of unsolicited contact by extractive industries, including logging, mining and oil and gas drilling. It’s estimated that a quarter are threatened by agribusiness, with a third terrorized by criminal gangs. Intrusions by missionaries are a problem for one in six groups.
- After contact, Indigenous groups are often decimated by illnesses, mainly influenza, for which they have little immunity. Survival International says that, if these peoples are to survive, they must be fully protected, requiring serious noncontact commitments by governments, companies and missionaries.

Radioactive leak in Banten exposes workers to danger & reveals regulatory failures
- A radioactive contamination scandal in Banten, Indonesia, has left local workers like Sakinah and Roni jobless and exposed to health risks after Cesium-137 was traced to factories in the Modern Cikande Industrial Estate.
- Government investigations revealed widespread contamination across 22 companies, prompting cleanup operations and health checks for more than 1,500 residents living near the exposure zone.
- Authorities have struggled to find secure storage for the contaminated materials while admitting regulatory lapses that allowed radioactive scrap metal to enter the country unchecked.
- Experts and environmental groups are now urging tighter import controls, improved radioactive waste management and stronger coordination among ministries to prevent another silent disaster.

Indonesia’s most vulnerable push for nation’s first Climate Justice Bill
- Climate change is forcing migration and deepening inequality across Indonesia, displacing rural residents, Indigenous peoples and those with disabilities — groups least responsible for the crisis.

Indonesia court clears wildfire scientists in case brought by palm oil company
- A district court in a Jakarta suburb has dismissed a lawsuit brought by palm oil company PT Kalimantan Lestari Mandiri against two scientists who provided expert testimony in a 2018 court case that found the palm oil firm liable for wildfires on hundreds of hectares of land in Central Kalimantan province.
- Bambang Hero Saharjo and Basuki Wasis, two professors at Bogor Institute of Agriculture, said defending the suit required time that could have been spent in the field or laboratory working to establish the facts in other cases.
- Civil society representatives responded to the ruling with relief. The heads of several nonprofits expressed hope that the verdict would provide reassurance to others that corporate actors had limited ability to use the courts against scientists.

Indonesia retiree rewilds world’s largest volcano lake as church demands plantation closures
- In 2005, career civil servant Wilmar Eliaser Simandjorang became the first district leader of Samosir, home to Lake Toba, the largest lake in Indonesia and largest volcanic lake in the world.
- After retiring, Wilmar devoted his time to building grassroots networks to rewild parts of Lake Toba, while advocating for greater environmental protection in the Sumatran upland.
- In 2013, Wilmar declined to accept the Wana Lestari prize awarded by Indonesia’s government, citing what he saw as shortcomings in government initiatives to manage the land.
- This year, the largest Batak church, the Batak Protestant Christian Church (HKBP), made a public call for the region’s largest plantation company, PT Toba Pulp Lestari (TPL), to be shut down.

New cluster of Tapanuli orangutans discovered in Sumatra peat swamp
- Researchers have confirmed that the critically endangered Tapanuli orangutan, previously thought to live only in Sumatra’s Batang Toru forest, also inhabits a peat swamp forest 32 kilometers (20 miles) away in the Lumut Maju village forest.
- DNA analysis of fecal samples verified the Lumut Maju apes as Tapanuli orangutans, marking the first confirmed record of the species outside Batang Toru.
- The discovery highlights the conservation value of nonprotected peat swamps, which are rapidly being cleared for oil palm plantations, threatening the orangutans’ survival.
- Conservationists warn that the isolated Lumut Maju population, likely fewer than 100 individuals, may not be viable long term unless habitat protection or relocation strategies are implemented.

Indonesia falls short in bid to increase its share of southern bluefin tuna catch
- The Commission for the Conservation of Southern Bluefin Tuna (CCSBT), a multilateral body that manages the stock of southern bluefin tuna, held its annual meeting Oct. 6-9 in Bali, Indonesia.
- Indonesia pushed for a larger share of the global catch, which is currently dominated by Australia and Japan, but CCSBT members instead kept each nation’s share unchanged.
- Members also agreed to once again fully fund a key stock monitoring program, and to set up a future meeting for discussion of seabird protection in the fishery, amid criticism from conservationists that the commission hasn’t done enough to protect seabirds.

Nickel mining threatens Raja Ampat ecosystems, communities & conservation: Report
- A new environmental report warns that expanding nickel mining is placing Raja Ampat’s coral reefs, forests and Indigenous communities under intensifying threat.

In Indonesia’s Mentawai Islands, youths blend ancestral and world faiths to protect forests
- In the Mentawai Islands of Indonesia, Indigenous youths continue to practice Arat Sabulungan, a cosmology that sees nature as filled with spirits, while blending it with Islam and Christianity.
- Researchers documented 11 rituals linking spirituality to forest management, such as offerings before tree felling and periods of abstinence, showing how traditions are adapted across generations.
- Scholars note that rituals can both restrain overuse and legitimize extraction, highlighting the complex role of Indigenous cosmology in shaping human-nature relations under modern pressures.
- Ongoing logging, land-use change and weak government support have stripped large tracts of forest from the Mentawais, undermining the islands’ ecosystems and the cultural practices tied to them.
