Boom in burning waste for fuel puts 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.

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.

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.

A new ‘fairy lantern’ species is found at a Malaysian picnic site
In November 2023, naturalist Gim Siew Tan chanced upon an unusual plant with whitish-peach flowers growing near the buttress of a tree at a popular picnic site in Hulu Langat Forest Reserve in Selangor, Malaysia. Researchers subsequently collected and analyzed specimens of the plant and found that it was a new-to-science species of “fairy lantern” […]
Reforestation and wild pig decline spark surge in miniature deer in Singapore
- Once thought extinct in Singapore, a little-known species of miniature deer has reemerged in unprecedented numbers on a small island reserve in the Johor Strait.
- Researchers documented the greater mouse-deer thriving on Pulau Ubin at the highest population density recorded anywhere in the species’ range.
- The team put the surge down to increased availability of prime habitat following a decade of forest restoration, as well as reduced competition for food after the collapse of the island’s wild pig population due to African swine fever.
- Experts say the dramatic “ecological cascade” underscores the need for long-term, ecosystem-wide monitoring throughout Southeast Asia, particularly at sites impacted by sudden shifts triggered by disease.

Once they have mastered the basics of climbing, building nests […]
Philippine mangroves survived a typhoon, but now confront a human-made challenge
- A new study shows mangroves in Tacloban, the Philippine city hit hardest hit by Typhoon Haiyan in December 2013, have expanded beyond pre-storm levels.
- This recovery was driven by community-led reforestation efforts from 2015-2018, when residents planted 30,000 Rhizophora mangrove seedlings across 4 hectares (10 acres) of Cancabato Bay.
- Satellite image analysis and modeling reveal how the forest was destroyed by Haiyan and how it later withstood 2019’s Typhoon Phanfone.
- However, experts warn that the recovering mangroves may be threatened by an ongoing project to build a causeway across the bay, which could generate pollution and physical disturbances.

Filipinos wade through floodwaters due to sinking land, rising sea & corruption
- Rising sea levels and sinking lands are leaving communities in the Philippines with the challenge of adapting to a combination of hazards that are reshaping coastal and island life.
- Globally, around 40% of the population lives in coastal areas, with more than 850 million people in low elevated coastal zones less than 10 meters above sea level, including more than 150 million living less than 5 above sea level.
- Between 2000 and 2019, an estimated 1.6 billion people were affected by different types of flooding, threatening infrastructure and disrupting basic services.
- On July 28, Philippine President Ferdinand Marcos Jr. in his State of the Nation Address ordered an investigation into possible corruption in flood control projects; since then, the scandal has ignited a broader anti-corruption movement among Filipinos.

More than 1,400 dead across Asia after ‘rare’ cyclone & typhoon converge
At least 1,400 people have died as a result of flooding and landslides across Sri Lanka, Indonesia, Thailand and Malaysia, with many more still missing. The unusual combination of a tropical typhoon and two tropical cyclones is behind the mounting humanitarian disaster. Scientists and meteorologists note that Cyclone Senyar formed just north of the equator, […]
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.

Endangered knowledge and endangered plants: Threats to Indigenous medicinal traditions in Borneo
- Borneo’s Indigenous Punan people’s centuries-old plant knowledge is fading as younger generations turn to modern medicine, and secrecy limits knowledge sharing.
- Two important medicinal species, Cissus rostrata and Coscinium fenestratum, face severe conservation threats.
- Researchers emphasize long-term partnerships with Indigenous communities as essential for preserving both biodiversity and cultural heritage.

Returning baby gibbons to the wild
Across Southeast Asia, the trafficking of gibbons is on the rise, as demand for them as pets on the black market has soared. On the frontline of this rising issue is the Sumatran Rescue Alliance which forms part of Orangutan Information Centre. But rehabilitating and releasing gibbons back to the wild can be a long […]
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.

What was achieved for Indigenous peoples at COP30?
- The two-week COP30 climate summit in Belém, Brazil, saw the largest global participation of Indigenous leaders in the conference’s history.
- With the adoption of measures like the Intergovernmental Land Tenure Commitment, a $1.8 billion funding pledge, and the launch of the Tropical Forest Forever Facility (TFFF), the summit resulted in historic commitments to secure land tenure rights for Indigenous peoples, local communities and Afro-descendant people.
- Yet despite these advances, sources say frustrations grew as negotiators failed to establish pathways for rapid climate finance for adaptation, loss and damage, or to create road maps for reversing deforestation and phasing out fossil fuels.
- While some pledges appear ambitious, Indigenous delegates say effective implementation of the pledges will depend on government transparency and accountable use of funds.

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.

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

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.

In Thailand, a cheap bottle crate hack gives tree saplings a fighting chance
- A recent study in Thailand finds that raising native tree seedlings inside repurposed bottle crates improves performance compared to standard methods in community-run nurseries.
- Saplings grown in bottle crates had better root formation and superior growth when planted out in a deforested site, thanks to better air circulation for the roots.
- Crating the saplings also saved on labor costs, which more than offset the cost of purchasing the crates.
- Adoption of the new method could improve the quality of saplings grown in community nurseries, a benefit for reforestation projects where sapling survival is key to success.

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.

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.

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.

‘Green’ energy transition leaves a dirty trail in the Philippines’ nickel belt
- Nickel mining in the southern Philippines is damaging the environment and health and livelihoods of local communities, according to a recent report from U.S.-based NGO Climate Rights International.
- The report looked at the Caraga region on the island of Mindanao, where 23 active nickel mines currently operate.
- Residents interviewed for the report cited siltation of rivers, farms and coastal areas as damage caused by nickel mines, as well as dust pollution during the dry season. They also listed human rights violations against people opposed to the mines.
- The vast majority of nickel mined in the region is exported to China.

Protecting Vietnam’s vast caves may have sparked a wildlife comeback
- Phong Nha-Kẻ Bàng National Park in Vietnam is billed as a successful example of sustainable tourism, with efforts to conserve the area’s unique caves and wildlife.
- The park’s management has implemented measures to limit tourism’s impact, such as restricting visitor numbers and offering guided tours, which has helped curb illegal hunting and logging.
- Local communities have benefited from tourism, with many former hunters and loggers now working as guides and porters, and wildlife populations are showing signs of recovery.
- The success of conservation efforts in the park has led to plans to expand protection to the Laotian side of the border, creating a transboundary UNESCO World Heritage Site.

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.

Cautious win for Indigenous groups in Malaysia as palm oil firm pauses forest clearing
- Indigenous Penan and Kenyah residents in Malaysian Borneo have filed a lawsuit and a complaint with Malaysia’s sustainable palm oil certifier, accusing palm oil company Urun Plantations of clearing natural forest within its concession along the Belaga River in violation of its lease and sustainability certification.
- Urun Plantations agreed in late October to pause development activities after a palm oil mill suspended buying palm fruit from the plantation.
- Satellite imagery and NGO field evidence indicate ongoing deforestation since 2023, while the company says it is only replanting previously developed land and denies breaching certification rules.
- The company maintains the project has local support, with the dispute underscoring growing tensions in Malaysia’s Sarawak state over palm oil expansion into remaining forests and Indigenous territories.

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.

Karen community fighting corn and coal for clean air in northern Thailand
- Northern Thailand is trapped in a cycle of air pollution driven by maize cultivation for the animal feed industry, with field burning each year choking the region in hazardous haze.
- Government crackdowns and “zero-burn” policies have failed because impoverished farmers see no viable alternative to burning amid falling yields and mounting debt.
- Deforestation, soil erosion and flooding linked to maize farming have devastated ecosystems and rural livelihoods across Chiang Mai province.
- Even as some communities ban maize cultivation to fight haze, new coal projects threaten to undo their gains, revealing Thailand’s conflicting approach to environmental governance.

Witch Hunt: Virulent fungal disease attacks South America’s cassava crop
- Witches’ Broom, a devastating fungal disease, has spread for the first time from Southeast Asia to Latin America, arriving in French Guiana in 2023 and has now infiltrated northern Brazil.
- Cassava is a vital crop for food security in South America and Africa, and a critical cash crop in Southeast Asia, where the fungal disease is spreading rapidly. More than 500 million people worldwide rely on cassava for their dietary needs.
- The pathogen has already caused massive cassava losses in Southeast Asia, with infection rates in some fields near 90%, and now it threatens food security in Latin America. Climate change is helping the fungus thrive and spread, as wetter conditions create an ideal environment for infection.
- Brazil has launched emergency measures, including funding research and farmer training, but scientists warn that without swift containment, cassava production across the tropics could face severe declines.

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.

Ethanol plant spills harmful wastewater into Philippine marine reserve
A chemical spill from an ethanol distillery has put one of the Philippines’ largest marine protected areas at risk. A wall retaining the wastewater pond of an ethanol distillery plant collapsed on Oct. 24, causing about 255,000 cubic meters (67 million gallons) of wastewater to flow into Bais Bay in the central Philippines, according to […]
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.

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

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.

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.

International Gibbon Day: Spotlighting the overlooked, underprotected ‘lesser apes’
Gibbons, commonly called lesser apes, aren’t as well-known as some of their great ape cousins like chimpanzees or gorillas. But the lives of these highly arboreal primates are no less fascinating. They reside in the canopy of the tropical forests of South and Southeast Asia, living in small family groups, each patrolling its own territory, […]
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.

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.
- Fishers and farmers say they’ve been driven abroad by collapsing livelihoods caused by erratic weather, only to face exploitation and unsafe working conditions overseas.
- Indigenous and disabled communities are also seeing their food security, mobility and safety undermined, yet they remain largely excluded from government responses and public discourse.
- Civil society and affected groups are pushing for Indonesia to pass a Climate Justice Bill, which would enshrine climate justice as a constitutional right and protect vulnerable communities through coordinate national policy.

Forest sanctuaries and spiritual balance in the Karen highlands of Thailand
- One of Thailand’s largest Indigenous groups, Karen Pgaz K’Nyau culture is deeply rooted in animist beliefs that emphasize the importance of living in balance with nature.
- Their approach to land management incorporates sacred and community forests and traditional small-scale farming, where rituals, prayers and customary regulations govern the use of natural resources.

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.

Unique diving paradise threatened by mine reopening
A nickel mine in Indonesia’s Raja Ampat archipelago was shut down in June after a mining ban, but operations restarted last September after the government claimed it was compliant with environmental requirements and could be considered a “green mine.” So what does the reopening mean?

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.
