Grassroots community seeds sorghum in eastern Indonesia to adapt to climate change
- In 2022, Ambrosia Ero and Hendrikus Bua Kilok joined forces in Lembata Island to boost locally grown food staples, including persuading a junior high school to plant a field of sorghum on the school estate.
- They helped establish a village organization, Gebetan, which began by documenting nutritious crops grown by past generations of Indigenous farmers on the island. They then conducted outreach to farmers on the resilience of sorghum to drought.
- The grass roots organization has won 84 million rupiah ($5,000) in funding to expand on this work with crops that are better able to withstand the increasingly adverse growing conditions in East Nusa Tenggara province owing to climate change.

Norway fund drops Eramet over Indonesia mine threatening forests, Indigenous tribe
- Norway’s $1.6 trillion government pension fund is divesting its $6.8 million stake in French miner Eramet after its ethics council found “unacceptable risk” of severe environmental damage and human rights violations at the PT Weda Bay Nickel mine the company operates in Halmahera, Indonesia.
- Weda Bay Nickel sits in the Wallacea Biodiversity Hotspot and has already cleared about 2,700 hectares (6,700 acres) of rainforest since 2019, far exceeding its plan, threatening endemic species and risking extinctions before they’re documented.
- Weda Bay Nickel sits in the Wallacea Biodiversity Hotspot and has already cleared about 2,700 hectares (6,700 acres) of rainforest since 2019, far exceeding its plan, threatening endemic species and risking extinctions before they’re documented.
- The case highlights growing investor scrutiny over whether nickel for electric vehicle batteries and other clean-energy technologies can be sourced without destroying tropical forests or violating Indigenous rights.

Critics say FSC update risks weakening accountability for forest harm
- The world’s biggest sustainable timber certifier has updated how it applies its “corporate group” rules, which determine whether certified companies are held responsible for violations by affiliates, suppliers or subsidiaries.
- NGOs like Forest Peoples Programme, Greenpeace and Rainforest Action Network warn the change could let forestry giants such as APP and APRIL rejoin the FSC without fully remedying past deforestation and land conflicts.
- The NGOs took part in the review process, but say it favored corporate voices and misrepresented civil society input, raising concerns that the update prioritizes company reputations over community rights.
- Critics say narrowing the corporate group scope risks shielding parts of conglomerates from scrutiny just as the FSC tests its remedy framework with some of the world’s largest forestry companies.

Ani Dasgupta watched wetlands tame floods in Kigali. He believes nature is infrastructure we can fund.
- Ani Dasgupta’s path runs from Delhi’s slums to the World Bank and now WRI, where he argues climate, nature, and development must move together. His leadership emphasizes moral purpose, trust, and “orchestration” that links funders, governments, NGOs, and communities to turn knowledge into action.
- He points to pragmatic models: post-tsunami Aceh’s collaborative rebuild, a Kenyan macadamia venture restoring land while raising incomes with Terrafund’s early support, and Kigali’s wetland revival culminating in Nyandungu Park. These show nature-based solutions can cut risk and create jobs, yet financing remains the bottleneck despite WRI’s estimate that $1 in adaptation yields $10 in benefits over a decade.
- Technology is a means, not a cure-all: radar-powered RADD alerts, Global Forest Watch, and WRI’s Land & Carbon Lab aim to democratize environmental intelligence, with AI lowering entry barriers. Evidence like Indigenous monitoring in Peru halving deforestation underpins his measured optimism that systems can bend if collaboration is real and benefits are visible.
- Dasgupta was interviewed by Mongabay Founder and CEO Rhett Ayers Butler in September 2025.

The Great Insect Crisis
Insects underpin ecosystems worldwide, yet they are disappearing at alarming rates. In this 2019 special series, Mongabay reporter Jeremy Hance traces the global scale of the so-called “Insect Apocalypse,” as reported in the mainstream media — from massive declines in flying insects in Germany to the near-collapse of arthropods in Puerto Rico’s forests. Drawing on […]
Indonesia reopens Raja Ampat nickel mine despite reef damage concerns
- Indonesia has allowed state-owned PT Gag Nikel to resume mining operations on Gag Island in Raja Ampat, despite a ban on mining small islands and a previous suspension imposed in June.
- A 2024 survey commissioned by Gag Nikel reported widespread community complaints of dust, health issues, sedimentation, and coral damage from barges — contradicting the government’s claims of minimal impact.
- NGOs say the “green” rating cited by the government to justify the resumption masks real destruction in Raja Ampat, one of the world’s richest marine ecosystems, and note the government has revoked other mining concessions in the area for similar impacts but not Gag Nikel’s.
- More than 60,000 people have signed a Greenpeace petition opposing mining in Raja Ampat, warning sedimentation could destroy coral reefs and threaten local livelihoods even as the nickel feeds Indonesia’s EV battery supply chain.

Indonesia flooding traced to corporate canals that drain peatlands: Report
- Flooding in Indonesia is increasingly traced to corporate destruction of peatlands rather than natural causes, according to a new report by NGO Pantau Gambut.
- The construction of industrial-scale canals poses a growing threat; the report found that 281,253 kilometers of canals have cut through peatland ecosystems, draining the peat and compromising its sponge-like function.
- In addition, the report concluded that peatland protection laws are deeply flawed, as they serve corporate profit interests, rather than environmental protection.

Indonesia’s giant Java seawall plan sparks criticism & calls for alternatives
- Indonesia has launched a massive new project on Java’s northern coast, framed as protection for millions of residents from worsening environmental threats.
- The plan has drawn sharp criticism from experts and activists who question its methods, costs and potential impact on vulnerable communities.
- Calls are growing for deeper public consultation and long-term solutions that go beyond quick fixes.

Vian Ruma, Indonesian activist, found dead. Aged 30.
He taught mathematics in a small state school on Flores and organized the parish youth group on weekends. Numbers ordered his days; community gave them purpose. In recent years, he also helped mobilize opposition to plans to tap the island’s restless geology for power. On Sept. 5, 2025, Vian Ruma was found dead, hanging from […]
Death of activist critical of geothermal project raises alarm in Indonesia
- Vian Ruma, a 30-year-old opponent of a geothermal project on Flores Island, was found dead under circumstances his family and allies say point to foul play.
- His death highlights Indonesia’s long and worsening record of attacks on environmental defenders, with activists saying most violence and killings of activists in the past decade have targeted this group.
- Under President Prabowo Subianto, cases of threats and attacks on environmental human rights defenders have more than doubled in early 2025 compared to the same period last year.
- Police and companies increasingly use criminal charges to silence critics, deepening fears among civil society of shrinking space to call out environmental violations.

Maluku coconut growers cry crisis as Indonesia land-grabs feed energy transition
- Numerous villages in Indonesia’s Halmahera Island face extensive compulsory purchase actions for farming land by mining companies with extraction permits issued by the government.
- One farmer said he faced sustained pressure from local authorities to accept offers of $1.22 per square meter of land, which did not account for the recurring revenues earned from multiple coconut harvests per year.
- The South Wasile’s police chief sent an emphatic denial to Mongabay Indonesia when asked whether local police were involved in company efforts to persuade farmers to sign contracts of sale.
- Mongabay has reported this year from Halmahera on a rise in respiratory disease and high levels of mercury present in blood samples in communities living alongside Weda Bay Industrial Park (IWIP), the giant nickel smelting center on Halmahera.

Indonesia prioritizes gas over renewables to meet power demand surge
- Indonesia’s state electricity company PLN is betting big on natural gas as a “bridging fuel” ahead of a big buildup of renewables.
- But it is at least half again more expensive than coal, and domestic supplies are running low.
- Critics say gas is costly, existing plants are underused, and the policy risks locking Indonesia into fossil fuels while diverting funds from clean energy.
- Domestic gas supply is also declining as wells age, raising fears of shortages by the mid-2030s unless new reserves are tapped.

Americans’ love of RVs tied to destruction of orangutan habitat: Investigation
- Investigations by the NGOs Earthsight, Auriga Nusantara and Mighty Earth have found that plywood from forests cleared in Indonesian Borneo — including critical orangutan habitat — is ending up in U.S. RVs made by brands like Jayco, Winnebago and Forest River.
- Logs from a concession held by PT Indosubur Sukses Makmur were traced to plywood giant KLAM, then exported via U.S. intermediaries (MJB Wood, Tumac Lumber and Patrick Industries) into RV manufacturing supply chains.
- Indonesia allows legal clearing of natural forests, while the U.S. bans only illegal logging under the Lacey Act — creating a loophole that lets deforestation-linked wood enter supply chains unchecked.
- FSC-certified sustainable alternatives exist and would add as little as $20 to an RV’s price, but RV makers prioritize low costs, critics say; experts call for stronger Indonesian protections and U.S. deforestation-free import laws.

EUDR implementation comes laden with potential unintended consequences
- The European Union’s regulation on deforestation-free products (EUDR) is set to enter into force at the end of 2025, after a one-year delay. Experts say this tool is needed to address deforestation within the bloc’s commodities supply chains, but experts say the EUDR, unless revised, may come with unintended consequences.
- A shift of deforestation-linked commodities from the EU to nonregulated markets (known as leakage) could undermine the EUDR, while smallholder farmers could be sidelined to more easily meet the regulation’s goals, worsening social problems, risking land use change and even causing harm to ecosystems beyond forests.
- Experts propose a range of measures to address these problems in advance of EUDR implementation, including direct forest protection, inclusion of other vulnerable ecosystems in the legislation and greater efforts by government and companies to help smallholders adapt to regulatory requirements.

New model reveals hidden dynamics of Indonesia’s booming songbird trade
- Researchers have built the first model mapping supply and demand in Indonesia’s vast songbird trade, finding that species traits like mimicry and rarity drive demand more than species identity.
- The study identified 332 species from trade data from 2015-2022, and grouped them into three demand clusters: competition birds, vulnerable species at risk from poaching, and household pets kept for status or rarity.
- Findings show substitution fuels the trade, with sellers offering similar species at different price points, quickly expanding pressure to new species and compounding conservation risks.
- The model offers a blueprint for conservation strategies, highlighting the need for market monitoring and community engagement to address cultural drivers behind the trade without triggering backlash.

Censured Sumatra coal plant blamed for sickening children in Indonesia’s Bengkulu
- A 2×100 megawatt coal power plant established by Chinese state-owned enterprise, Power Construction Corporation of China (PowerChina), incurred environmental penalties in 2023 from Indonesia’s environment ministry for dumping fly ash into a protected marine area off the city of Bengkulu in Sumatra.
- Residents of Teluk Sepang in 2019 formed a grassroots organization to advocate for clean air while holding to account PowerChina’s Indonesian affiliate, PT Tenaga Listrik Bengkulu.
- Data from a local clinic in Teluk Sepang showed a large share of young people living in the shadow of the coal plant suffer from respiratory diseases.

On Java’s Mount Slamet, two former trappers find new calling as bird protectors
- Ari and Junianto began hunting birds as children in the foothills of Java’s Mount Slamet, near their home in Sambirata village.
- Trapping birds for the illegal wildlife trade became their main livelihood over time, with much of the trade shifting from local markets to social media as the pair came of age and internet access proliferated.
- Ari and Junianto’s view of their vocation shifted in their 20s, and they began to work with conservation organizations to help map bird nests and protect forest areas. Today the pair are active conservationists in Banyumas district, giving talks in schools on the district’s birdlife and working with local charities.
- Banyumas, and the wider Central Java province, is home to numerous endangered and critically endangered species of birds owing to the trade in caged birds, according to the conservation authorities.

Indonesia’s fish farm expansion to absorb D.C.-sized swath of protected forests
- This year, Indonesia’s government announced the first stage of a five-year plan to expand and intensify aquaculture production on 78,000 hectares (193,000 acres) along the north coast of Java Island.
- The first phase, 20,400 hectares (50,400 acres), will cover four districts in West Java province.
- Civil society leaders in Indonesia point to problematic experiences with similar “strategic” projects administered by the central government, adding that the initial plan in West Java risks further diminishing local fishers’ standing, rather than stimulating the community economy.
- A review of zoning documents by Indonesian environment watchdog Walhi showed the initial stage in West Java would include reclassifying 16,078 hectares (39,730 acres) of protected forests for the project — an area nearly the size of Washington, D.C.

Small islands offer big hope for conservation of endemic species, study shows
- New research in Indonesia shows that small islands, often considered extinction hotspots, can act as crucial refuges for rare mammals like the anoa and babirusa, which face severe threats from deforestation and poaching on larger land masses.
- Genetic analyses of more than 110 individuals revealed that while small-island populations have lower genetic diversity and higher inbreeding, they also carry fewer harmful mutations — likely because long-term isolation allowed natural selection to purge them.
- Smaller islands were also found to host higher-quality, better-protected forest habitats, suggesting that conserving these areas may be more effective than attempting “genetic rescue” by moving animals from mainland populations, which could introduce harmful mutations.
- The study highlights the need to refine taxonomy, prioritize protection of small-island habitats, and integrate these overlooked areas into conservation planning, as they may hold the key to the long-term survival of iconic and endemic small-island mammals.

Can we undo extinction? A growing effort to restore lost sharks
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In the turquoise shallows of Raja Ampat, Indonesia, a conservation experiment is attempting the rewilding of an endangered shark. The initiative, known as ReShark, seeks to restore populations of the Indo-Pacific leopard shark (Stegostoma tigrinum), also called the […]
Global brands join drive for deforestation-free palm oil in Indonesia’s Aceh
- Major brands including Nestlé, PepsiCo and Unilever have launched the Aceh Sustainable Palm Oil Working Group to align with a new road map for deforestation-free palm oil in the Indonesian province.
- Aceh, on the island of Sumatra, is home to the Leuser Ecosystem and other critical habitats, but has lost nearly 42,000 hectares (104,000 acres) of forest since 2020, much of it driven by expansion of oil palm plantations.
- The initiative aims to boost the livelihoods of smallholder farmers, protect high conservation value forests, and help producers comply with new global rules like the EU Deforestation Regulation.
- While the plan has drawn international backing, civil society groups stress its success depends on ensuring accountability, transparency and sustained pressure to halt illegal deforestation.

Rare Javan leopard sighting renews focus on conservation, monitoring efforts
- A rare Javan leopard was recorded on camera in Mount Lawu forest, Central Java, after officials installed camera traps following a hiker’s report.
- The endangered big cat’s presence highlights Mount Lawu’s ecological importance, where Tahura Mangkunagoro park conserves diverse plants, birds and mammals.
- With only around 350 Javan leopards left in the wild, the sighting underscores urgent threats to the species from habitat loss, hunting and human pressure.
- Authorities and conservation groups are expanding camera-trap surveys and preparing a 2026–2031 action plan to safeguard the species through better monitoring, habitat protection and community engagement.

Indonesia’s Bajau fishers lament nickel mining’s marine pollution
For many members of the nomadic Bajau sea tribe on Indonesia’s Kabaena Island, growing up meant swimming and fishing in clear waters, just outside their homes built on stilts. However, in 2010, the water turned red, which the villagers blame on runoff from nearby nickel mining, Mongabay’s Hans Nicholas Jong reported in July. “Now, I […]
Sustainable biomass certification scheme is flawed, degrades forests, report finds
- The Sustainable Biomass Program (SBP) is a private certification scheme developed by the bioenergy industry to assure the sustainability of biomass for fuel. A new report alleges that SBP is certifying biomass whose production has caused forest degradation.
- The NGO-commissioned report raises questions about SBP’s certification process, especially methods for verifying wood pellet producer and supply chain sustainability claims to safeguard against deforestation and forest degradation. SBP certification is used to justify green subsidies to the industry, mostly by European nations, but increasingly in Asia.
- SBP acknowledges the concerns raised by the report and said it is open to dialogue. The organization emphasized that its standards are designed to assess “the sustainability and legality of biomass sourcing at the level of the Biomass Producer, not at the forest management unit level” and that it does not “make overarching climate impact claims.”
- The nonprofit environmental groups that commissioned the report question how SBP can assure sustainability without assessing forest management and climate impacts.

New coalition focuses on ‘reuse’ to tackle top polluter Indonesia’s plastic waste problem
- Thirteen organizations and businesses in Indonesia have launched the Indonesian Reuse Association (AGUNI) to promote sustainable reuse systems as an alternative to single-use plastic.
- AGUNI members, ranging from micro-enterprises to startups, already operate more than 1,000 refill and reuse access points nationwide.
- Indonesia faces a severe plastic waste crisis, leaking an estimated 1.3 million metric tons of plastic into the ocean annually, making it one of the world’s top marine polluters.
- Experts say reuse is more sustainable than recycling, and AGUNI aims to scale adoption, strengthen member capacity, and support a circular economy that reduces pollution and benefits the economy.

Indonesia’s idle land problem
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Indonesia is defying the global trend in tropical deforestation. While forest loss in much of the tropics reached record highs in 2024, Indonesia’s rate fell by 14% compared with the previous year. Yet beneath this apparent success lies […]
Pulp and paper giant APP moves closer to regaining FSC stamp despite pending review
- The Forest Stewardship Council has allowed Asia Pulp & Paper — “one of the world’s most destructive forestry companies” — to resume its remedy process toward regaining certification it lost in 2007 for deforestation and land conflicts.
- Watchdog groups say the decision is premature because a legal review of APP’s links to Paper Excellence/Domtar, the biggest pulp and paper company in North America, is still unfinished.
- Critics warn the move could erode trust, enable greenwashing, and expose communities in conflict with APP-linked companies to further harm.
- NGOs are calling for the remedy process to be paused until the review is completed and for full transparency on corporate ownership and compliance.

Indonesia’s aquafarm revamp sparks fears for fate of farmers and mangroves
- Indonesia plans to revitalize 78,000 hectares (193,000 acres) of state-owned aquaculture ponds, starting with 20,400 hectares (50,400 acres) in West Java province, aiming to boost yields, create 119,000 jobs and attract investors.
- Small-scale farmers like Warno in Karawang district, who rent and maintain ponds from the state, say they fear losing their livelihoods without compensation if the government takes over their farms.
- NGOs and experts warn the program could fuel mangrove clearing, coastal damage and privatization of coastal areas, while sidelining local communities’ rights and voices.
- Critics also raise concerns over the government’s push for more farming of saltwater tilapia, citing risks from the invasive species and an industrial aquaculture model that could reduce locals to laborers.

How Indonesian companies dodge fines for forest & peatland fires
- While Indonesia’s courts have fined plantation companies more than $21 trillion rupiah ($1.3 billion) for forest and peatland fires, almost none of that money has been collected.
- This fuels a cycle of impunity where fires continue to flare up in concessions already found guilty by court.
- In a common pattern, companies found guilty of burning forests either shield their assets, declare bankruptcy or exploit loopholes to avoid paying.
- Indonesia’s enforcement gaps also allow repeat offenders to continue operating unchecked, profiting from the very land they were banned from using.

World Orangutan Day: Ongoing threats & habitat loss haunt these great apes
Despite years of research into their complex behavior and intelligence, orangutans remain critically endangered on the islands of Borneo and Sumatra, where they’re endemic. Mongabay has extensively covered the threats they face from habitat degradation and what studies say about how human activities affect them. This World Orangutan Day, on Aug. 19, we take a […]
Air quality study of East Java waste-to-energy plant sparks dispute, health warnings
- Indonesia’s largest environmental group reported that air quality around Surabaya’s Benowo waste-to-energy plant frequently exceeded World Health Organization safety limits, with pollution spreading into residential areas, markets, schools and other public spaces.
- Officials and the plant’s operator disputed the findings, maintaining that government-approved monitoring shows no breaches of pollution thresholds, while refusing to release the data.
- Environmental health experts warned that fine and coarse particles from waste burning can cause respiratory illness, heart disease and cancer, urging stricter standards, better waste separation and a shift toward community-based zero-waste systems.

NASA satellites show surge in Indonesia hotspots as 2025 fires send smoke to Malaysia
- NASA satellite data show a dramatic uptick in fire hotspots across Indonesia, with smoke from Sumatra detected in Malaysia in late July.
- The July spike follows early warning signs in May and June, with most fires detected in peatlands and fire-prone agricultural areas, raising alarms over worsening air quality, public health, and environmental damage.
- Activists warn the 2025 fire season could be one of the worst in recent memory, rivaling past disaster years.
- The crisis unfolds a decade after Indonesia’s 2015 fire disaster, which burned 2.6 million hectares, caused an estimated 100,000 premature deaths, and triggered a regional haze crisis affecting Singapore and Malaysia.

Can we undo extinction? A growing effort to restore lost sharks
- ReShark is the world’s first shark rewilding program, aiming to restore Indo-Pacific leopard sharks to reefs where they’ve disappeared, starting in Raja Ampat, Indonesia.
- The initiative repurposes surplus eggs from aquariums, transporting them across oceans and rearing them in locally managed hatcheries before releasing them into the wild.
- A growing community of Indonesian conservationists—including trained “shark nannies,” students, and villagers—is central to the project’s success and sustainability.
- With global collaboration and scientific rigor, ReShark aims to produce a model for reversing extinction—one grounded in genetics, local stewardship, and public engagement.

Study maps rare Borneo forests with unique habitats & urgent need for protection
- A new study has mapped lowland heath forests (kerangas) in Indonesian Borneo, revealing major changes in their extent and limited formal protection.
- In Central Kalimantan’s Rungan-Kahayan landscape, researchers documented unique habitats rich in biodiversity but surrounded by competing land uses.
- They noted that these forests are often overlooked due to misconceptions about their soils, despite their ecological and cultural importance.
- The study calls for urgent action to better understand, protect and sustainably manage these rare ecosystems.

Borneo killing linked to coal industry stays unsolved as Indonesia VP visits Dayak village
- On Nov. 15, 2024, two Indigenous men were attacked before dawn at a checkpoint in Muara Kate, a roadside hamlet in East Kalimantan province, established by the local population to enforce a ban on mining vehicles using local roads. This community decision followed the death of a young pastor a month earlier in an accident with a coal truck.
- Police have questioned staff from coal miner PT Mantimin Coal Mining in connection with the case, but at the time of writing, authorities had yet to name any suspects in connection with the November murder.
- In June, Indonesia Vice President Gibran Rakabuming Raka visited the community where the killing took place; an aide to the vice president said a report would be made to President Prabowo Subianto.
- Killing of environmental defenders in Indonesia is rare compared with countries like Brazil and the Philippines, but political scientists say democratic conditions in Indonesia have been eroded in the past decade.

Who is clearing Indonesia’s forests — and why?
- Most tropical countries are experiencing record-high deforestation rates, but in Indonesia, forest loss is slowing.
- But nearly half of the forest cleared in 2024 can’t be linked to an identifiable driver, raising red flags about speculative land clearing, regulatory blind spots and delayed environmental harm.
- Land is often cleared but not immediately used; research shows that nearly half of deforested lands in Indonesia remain idle for more than five years.
- Experts say these trends signal regulatory failure, as the government issues permits widely and concession holders face few consequences for clearing forest and abandoning the land, creating a cycle of destruction without accountability.

Indonesian farmers plant hope for isolated Javan gibbons
In Indonesia’s Central Java province, two groups of Javan gibbons have become isolated in two small forest patches. To help the gibbons make their way to larger forest areas, a local NGO, SwaraOwa, is working with farmers in the region to restore and build “corridors” that would connect the fragmented forest blocks, Mongabay reported in […]
As Indonesia reclaims forests from palm oil, smallholders bear brunt of enforcement
- Indonesian authorities have reclaimed 2 million hectares (5 million acres) of forest from illegal oil palm plantations under a militarized crackdown, but critics say it disproportionately targets Indigenous communities and smallholders while sparing large corporations, deepening land inequality.
- Much of the reclaimed land is being handed over to state-owned plantation company PT Agrinas Palma Nusantara, raising concerns that private monopolies are being replaced by a state one, with some communities pushed into profit-sharing schemes critics call exploitative.
- In biodiversity-rich Tesso Nilo National Park, thousands of families are being forcibly evicted, while powerful figures like a local legislator evade sanctions, highlighting a two-tiered policing system.
- Activists are calling for a new forestry law to address outdated legislation, protect Indigenous land rights, mandate ecological restoration, and close legal loopholes that allow corporate violators to avoid accountability.

Civil society challenges Indonesian deregulation law over rights and environment
- Indonesia’s controversial Job Creation Law is facing new legal challenges from civil society groups who say it weakens environmental protections and human rights.
- One lawsuit targets provisions that restrict public involvement in environmental impact assessments and remove key legal tools for opposing harmful projects.
- A second lawsuit challenges special privileges granted to large-scale infrastructure projects, accusing the law of facilitating forced evictions and land grabs.
- A case study cited in the legal battle is the Rempang Eco City project, which residents say has displaced Indigenous communities without their consent and through the use of violence.

Batang coal plant’s seawater permit imperils marine life, fishing communities
- The Batang coal-fired power plant in Central Java, now legally permitted to use vast amounts of seawater for cooling, has raised alarms among experts over its impact on marine ecosystems and traditional fisheries.
- Since operations began, the plant has displaced fishing communities, polluted coastal waters with heated discharge and caused up to a 50% decline in shrimp catches, particularly affecting traditional fishers in Roban Barat.
- Community resistance was met with intimidation and arrests, while some residents accepted compensation from the operator, PT Bhimasena Power Indonesia, further dividing the local population.
- Critics, including Greenpeace and KIARA, say the project reflects Indonesia’s coal-centered energy policy, undermining both environmental justice and climate goals, as the country continues to expand fossil fuel use despite international pressure to shift toward renewables.

Across Southeast Asia, Indigenous women challenge extraction and erasure
- Across Southeast Asia, Indigenous women activists face discrimination, repression and violence, while often being excluded or unsupported even within their own communities.
- Among them is Maria Suryanti Jun, who is leading opposition to a geothermal project in Poco Leok, Indonesia, citing a lack of transparency and free, prior and informed consent from the community.
- Women like Maria face unique challenges in environmental defense due to patriarchal norms, limited education and cultural roles — but are often deeply connected to the land and emerge as key defenders.
- Despite obstacles, these activists are building solidarity and pushing for change through international advocacy, capacity-building programs, and expanding women’s access to education and leadership.

Where there’s political will, there’s a way to stop tropical deforestation, study finds
- A study focused on why deforestation rates have slowed in Indonesia and the Brazilian Amazon revealed that political will was a critical factor, often as a result of pressure from civil society and diplomacy to conserve forests.
- The authors surveyed the expert opinions of researchers, policymakers and advocates working on forest conservation in Brazil or Indonesia.
- In Brazil, experts said government action — like satellite monitoring and recognizing Indigenous lands — was key to stopping deforestation.
- Indonesia’s forest conservation success comes not just from political will, but also from corporate efforts and pressure from civil society groups.

Indonesian palm oil company sues experts who helped secure $18m pollution ruling
- Two top Indonesian environmental experts, Bambang Hero Saharjo and Basuki Wasis, are being sued by palm oil firm PT Kalimantan Lestari Mandiri for their court testimony that helped convict the company for massive fires in Borneo.
- The lawsuit is widely condemned as a SLAPP (strategic lawsuit against public participation) — a legal tactic to silence critics — and raises concerns about the chilling effect on scientists who testify in environmental cases.
- Despite existing anti-SLAPP regulations in Indonesia, poor enforcement has allowed such lawsuits to proceed, with activists calling the case a form of judicial harassment and an attempt to evade responsibility for ecological damage.
- The case highlights broader issues of corporate impunity and weak enforcement of environmental rulings, as the company continues to operate and burn peatland, even after a binding court order to pay fines and restore the land.

Orangutans make up for lost sleep with daytime naps, study finds
- New research based on more than a decade of field observations indicates that wild Sumatran orangutans balance their sleep needs much like humans do, by napping during the day.
- The team found the shorter an individual’s sleep period overnight, the longer was its cumulative nap period the next day.
- Orangutan sleep also varied with temperature, activity levels and proximity of others, indicating the great apes have to trade off between foraging, socializing, traveling and sleep.
- Deforestation, habitat fragmentation and climate change are all likely to influence the capacity of orangutans to manage their sleep needs, with clear consequences for their overall health and survival.

Nickel boom on an Indonesian island brings toxic seas, lost incomes, report says
- Nickel mining on Indonesia’s Kabaena Island has polluted the sea, degraded forests and disrupted the lives of Indigenous Bajau fishers and farmers, who have reported severe drops in income, fish catches and seaweed quality.
- The mining has harmed biodiversity, threatening leatherback turtle nesting sites and the island’s unique long-tailed macaques, while also causing health issues among locals, including skin and respiratory problems, according to a report by NGOs.
- Affected communities report land seizures without proper consultation or compensation, limited public participation, and criminalization of protests, all in violation of Indigenous rights and national laws.
- The report ties the mining firms to political elites and global EV supply chains, including alleged links to Tesla and Ford, and calls for mining permit audits, stronger protections for affected communities and full accountability from companies.

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

Burning, burying and banning: Indonesia’s cities struggle to manage their garbage
- Indonesia’s garbage crisis is growing, with illegal dumping and unmanaged waste threatening communities, tourism, and ecosystems — as seen in the unsanctioned disposal of nearly 200 truckloads of trash near a popular beach in Yogyakarta.
- Despite a 2008 law banning open dumping, enforcement has long been delayed, but as of April 2025, the central government has officially ordered the closure of 343 landfills and threatened jail time for noncompliant local officials.
- Local governments are scrambling to comply, with some cracking down on illegal dumping, promoting waste sorting, or offering cash incentives — though problems like corruption, poor infrastructure, and public resistance to waste separation persist.
- Experts say lasting solutions require public cooperation, better funding, and consistent enforcement, as Indonesia struggles to change long-standing attitudes and behaviors toward waste management.

Hope and frustration as Indonesia pilots FSC’s logging remedy framework
- Indonesia is the first test case for the Forest Stewardship Council’s new remedy framework, which allows logging firms to regain ethical certification by addressing past environmental and social harms.
- However, NGOs have found serious flaws in the process, including lack of consent, rushed assessments, and exclusion of many affected Indigenous communities.
- The process also faces backlash over poor transparency, intimidation of Indigenous rights activist, and allegations of undisclosed corporate ties to ongoing deforestation.
- Some communities see the framework as a rare chance to reclaim land and rights — but only if it becomes truly fair and accountable.

Strengthening global forest certification and delivering remedy: Interview with FSC’s Subhra Bhattacharjee
- The Forestry Stewardship Council, a voluntary global certification was established in 1993 by environmentalists, Indigenous groups, human rights advocates and the timber industry to help ensure sustainable forestry practices.
- A recent report has raised alarm over the implementation of the remedy framework, which allows companies to reclaim certification if they redress past environmental and social harms.
- Mongabay interviewed FSC’s new director-general, Subhra Bhattacharjee, who stressed Indonesia’s role in how the remedy framework will be implemented worldwide.
- “When you think of Indonesia, you think of these lush natural tropical forests. You think of the breadth of the biodiversity … sometimes it takes my breath away, the kind of biodiversity we have. The world depends on these natural tropical forests,” she says.

Study finds worrying uptick in proboscis monkey trade in Indonesia
- Proboscis monkeys, endemic to Borneo, are threatened by habitat destruction, forest fires and hunting. But until two decades ago, trade wasn’t a threat to the CITES-listed species, which is challenging to keep in captivity.
- A recent study, analyzing 25-year seizure and trade data involving proboscis monkey trade, finds nearly 100 individuals in trade in Indonesia, with an alarming rise in online trade and zoo exchanges in recent years, many of which are likely acquired from the wild.
- Conservationists say this uptick in trade poses a threat to the endangered species and urge Indonesian authorities to enforce existing legislation to protect proboscis monkeys from trade. They also say social media platforms must do more to curb wildlife trade on their platforms, which is also a concern for proboscis monkeys.

Indonesia moves to revise sea sand export policy after court ruling
- Indonesia’s Supreme Court earlier this year struck down key parts of a 2023 regulation allowing sea sand exports, citing legal contradictions and environmental risks.
- The annulled policy had reversed a two-decade ban and faced backlash for potentially harming marine ecosystems and coastal communities.
- The government now says it’s revising the regulation, arguing that dredging can benefit ocean health and support domestic infrastructure projects.
- Critics warn the practice threatens fisheries, marine carbon stores and long-term sustainability, and call for a shift toward restoration over exploitation.

Sharks didn’t rebound—so Mark Erdmann is putting them back
- For over 30 years, Mark Erdmann has combined scientific discovery with grassroots conservation in Indonesia, helping communities protect their reefs from destructive practices and documenting more than 220 new species.
- As a leader behind Raja Ampat’s pioneering community-governed marine protected areas, Erdmann has shown how local stewardship can revive ecosystems—bringing back sharks, rays, and sustainable tourism.
- Despite new threats like over-tourism and revived mining, Erdmann remains hopeful, pointing to rising public resistance, tech-enabled rewilding programs like ReShark, and a new generation of Indonesian conservationists.
- Erdmann spoke with Mongabay Founder and CEO Rhett Ayers Butler during a voyage in the Pacific in June 2025.

Indonesian civil society urges probe after payout for mine recovery that never happened
- The former head of the East Kalimantan provincial mining agency is facing corruption charges, after he allegedly disbursed a guarantee payment used for environmental restoration to a company in East Kalimantan province.
- Muhammad Muhdar, an environmental lawyer at Mulawarman University in Samarinda, the provincial capital, told Mongabay that gaps in land rehabilitation of closed mining pits are so extensive that there’s potential for further unlawful activity to come to light.
- Data from the Mining Advocacy Network, a civil society organization known as Jatam, showed more than 1,700 former coal mine sites in East Kalimantan province, and that around 39 people had died in the excavations, most of them children.

Indonesia tests shows blood mercury rising at ground zero of world energy transition
- Pathology results from a sample size of 46 people living near Indonesia’s Weda Bay Industrial Estate (IWIP) showed a large share in the community around the nickel-processing center had unsafe levels of arsenic and mercury in blood samples.
- The precise cause of these elevated levels of a heavy metal is difficult to determine, but researchers suspect the health effects could be due to IWIP’s coal-fired power sources, pollution from the smelting process, and other environmental factors, such as accumulation in the food chain.
- Globally, research has shown links between heavy metals in the blood of people living alongside mining operations and elevated risks of chronic health conditions, as well as impairment of cognitive development in children.

Listings of Indonesian islands renew fears of privatization for coastal communities
- Listings of Indonesian islands on a foreign real estate site have sparked concerns about privatization, prompting the government to block the site domestically and clarify that islands cannot be sold to foreign entities under national law.
- Officials said the listings were likely aimed at attracting investment, not outright sales, but critics warn such practices enable control over island and offshore areas, often displacing fishers and triggering land conflicts.
- A 2021 regulation allows foreign investors to lease small islands for up to $1,900 per km² per year, and a government portal launched in 2024 streamlines permits for islands smaller than 2,000 km², accelerating commercialization.
- Watchdogs say 254 small islands have already been privatized, often without adequate oversight, and warn that unchecked investment could jeopardize fisher livelihoods and national sovereignty over maritime territories.

Study urges legal protection for Sulawesi’s endangered bear cuscus amid habitat loss
- A new study has revealed that the endangered bear cuscus in South Sulawesi occupies a highly fragmented and shrinking habitat, with less than 1% of surveyed areas deemed suitable, largely due to poaching, mining expansion and forest loss.
- Despite being previously protected, the species was excluded from Indonesia’s 2018 protected species list, and researchers argue this oversight must be corrected given the animal’s vulnerability and ecological importance.
- The study also highlights the cuscus’ broader scientific significance as one of the few marsupials in western Wallacea, as well as its cultural and emotional value to local communities that have learned to coexist with it.
- Experts and the study’s authors urge stronger habitat protection, stricter environmental controls and greater public engagement to ensure the species’ survival.

UN calls out Indonesia’s Merauke food estate for displacing Indigenous communities
- U.N. special rapporteurs have raised concerns that Indonesia’s food estate project in Merauke district is displacing Indigenous communities, clearing forests without consent, and using military forces to suppress dissent, threatening more than 50,000 Indigenous people.
- They point to deforestation of more than 109,000 hectares (269,000 acres), loss of biodiversity, and violations of Indigenous rights, including lack of free, prior and informed consent (FPIC) and intimidation by military forces.
- The Indonesian government has rejected the allegations, claiming compliance with national laws, and saying the project boosts food security and that Indigenous rights and environmental safeguards are respected — despite civil society calling these claims misleading.
- NGOs are urging stronger U.N. monitoring, a fact-finding mission, and genuine FPIC processes, warning that the project risks erasing Papuan Indigenous culture while facilitating corporate land grabs.

How Mongabay Indonesia grew into a trusted environmental voice
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. When Ridzki Sigit first joined Mongabay in 2012, the environmental journalism platform had yet to establish itself in the language of his native Indonesia. The concept was unconventional: a remote, international team with no physical office, focused solely […]
Camera traps and Indigenous knowledge help confirm presence of ‘lost’ echidna species
In November 2023, Mongabay reported on an expedition in which researchers partnered with Indigenous communities and government agencies in Indonesia’s Cyclops Mountains to capture camera-trap images of what was previously thought to be a “lost” species: Attenborough’s long-beaked echidna, the world’s rarest egg-laying mammal. Those findings have now been confirmed in a new study. Listed […]
Natural bridges to reconnect the last Javan gibbons
JAVA — Indonesia. Throughout the misty mountains of central Java, the call of the Javan gibbon (Hylobates moloch) once echoed throughout the forest. Today, their voices are fading. Java is one of the most densely populated regions on Earth, and decades of logging, agriculture and infrastructure development have fragmented the forest, while rampant hunting and […]
