Escalating Wildfires Threaten Lives, Health and Biodiversity in Indonesian Borneo
By Drooid · · How we work
Core Event
Since early 2026, a “super” El Niño has driven an unprecedented wildfire season across West Kalimantan, Borneo. Satellite monitoring shows thousands of hotspots burning peatland and forest, producing hazardous haze that blankets Pontianak and drifts across neighboring countries.
Background & Context
Indonesia’s dry season, intensified by El Niño warming of Pacific sea-surface temperatures, has created prolonged drought. Traditional slash-and-burn clearing for oil-palm plantations is reported as the primary ignition source, while peat soils prolong fire persistence.
Data & Statistics
- Burned area: Government data record 202,000 ha burned from January to July; YKAN estimates an additional 600,000 ha in August, with the Nusantara Atlas model projecting ? 900,000 ha total by end-August.
- Emissions: Indonesia emitted 19.7 million metric tons of fire-related pollutants during the week to 7 Sept, over one-third of the global total.
- Health impact: Respiratory-illness visits in the seven affected provinces rose from 50,891 on 1 Sept to 113,336 by 9 Sept. Over 12.5 million people have been exposed to haze, according to the health ministry.
- Biodiversity risk: The Cabang Panti orangutan research station lies within 200 m of active flames; five long-term study orangutans were observed fleeing the fire.
Impact
Human Health
Residents and firefighters receive oxygen cylinders through the “Rumah Oksigen” campaign. Popong Solihat, head of a Pontianak health clinic, notes a sharp rise in respiratory cases.
Wildlife and Research
The fire threatens the only remaining low-land rainforest tract in Borneo, endangering habitat for more than 2,500 Bornean orangutans. Researchers warn loss of forest could render the Cabang Panti data set unusable.
Community Response
Volunteer groups such as Power of Mama—Indonesia’s first all-female firefighting team—patrol high-risk zones, record hotspots with drones and educate villagers about safer land-clearing methods. Over 40 local assistants, staff and villagers have built firebreaks and improvised sprinkler systems to protect the station.
Official Statements & Responses
President Prabowo Subianto announced a presidential instruction banning land-clearing by fire and pledged to revoke permits of violators. The Ministry of Forestry reported a recent decline in “high-confidence” hotspots in Central and West Kalimantan, while acknowledging ongoing activity elsewhere. Copernicus senior scientist Mark Parrington warned that seasonal fire emissions and regional haze are already above normal levels. YIARI director Karmele Llano Sanchez described peatland fires as “very difficult to put out” because they burn below the surface.
Verbatim Quotes
- “It is very difficult to put out peatland fires since the fire is below the surface,” — YIARI
- “Orangutans are fleeing from these forests. It’s just horrible,” — Prof Cheryl Knott, Boston University
- “Five orangutans from our long-term study population were observed fleeing the fire, some only metres from the flames,” — Wahyu Susanto, Yayasan Palung
Conflicting Reports & Gaps
Estimates of total burned area vary dramatically: official figures (202,000 ha) contrast with independent assessments (600,000–900,000 ha). Health impact data differ in scope; Reuters provides provincial case counts, while AP notes more than 1.4 million students nationwide affected by school closures. No comprehensive, independently verified assessment of total economic loss or long-term ecological damage has been released.
What’s Next
The government has ordered the Ministry of Forestry to enforce the new land-burning ban. International assistance continues, with Japan supplying aircraft for water-bombing and cloud-seeding, and other nations offering additional aerial resources. Meteorological forecasts predict the El Niño will peak this month, sustaining dry conditions and limiting natural rainfall relief.
