Indonesia’s 2026 Wildfire Crisis: Super El Niño Fuels Record Emissions and Regional Haze

Core Event – Escalating Fires Across Sumatra and Borneo
In 2026 Indonesia’s fire season has intensified across Sumatra and the Indonesian part of Borneo. By early September, authorities reported that 76,933 hectares (190,106 acres) have burned, while satellite maps show more than 200,000 hectares consumed since early July. The fires are driven by an unusually strong “super” El Niño that has produced prolonged drought, and by human activities that drain peatlands for agriculture. Water-bombing aircraft, cloud-seeding planes and three Japanese CH-47 Chinook helicopters are being deployed to combat the blazes.
Background & Context – Super El Niño and Peatland Vulnerability
El Niño depresses rainfall across Indonesia; the 2026 episode coincides with a positive Indian Ocean Dipole, amplifying dryness. Indonesia holds roughly 36 percent of the world’s tropical peatlands, water-logged soils that store ancient carbon. When peat is drained it becomes a “vast reservoir of ready fuel,” allowing fires to smolder underground for weeks and release large quantities of carbon and fine particles. The 2015 super El Niño produced the last comparable crisis, burning 2.6 million hectares and causing an estimated 100,000 premature deaths.
Impact – Health, Air Quality, and Regional Spread
The thick smoke has drifted to Malaysia, Singapore, the Philippines and beyond, reducing visibility to less than 1 kilometre in parts of Pontianak. Residents report coughing, shortness of breath, sore throats, fever, diarrhoea and vomiting. Schools across Kalimantan and Sumatra have shifted to remote learning, affecting more than 250,000 students. Flights have been delayed and national parks closed, disrupting tourism and transport.
Official Statements & Responses – Government and International Action
Indonesia’s Defence Ministry announced that the Japanese helicopters will operate from Pontianak, adapting flights to hotspot movement. A Defence spokesperson said water sources are being drilled to support aerial drops. The Environment Ministry expressed “concern” over hazardous AQI readings and is monitoring Copernicus data, noting that satellite-derived emissions do not directly reflect local air quality.
Mark Parrington, senior scientist at the Copernicus Atmosphere Monitoring Service, warned that “emissions worsen global warming and climate change, which in turn can increase the frequency and severity of drought and fire conditions.”
On-the-Ground Reports – Volunteer Firefighters and Residents
Dayak volunteers are using hand tools and portable pumps to battle fires that have carbonised 200,000 hectares. In Pontianak, resident Fatmawati said visibility was “less than 1 kilometre” and that water supplies had turned black from soot.
Conflicting Reports & Gaps – Satellite Detection Limits and Emission Estimates
Ecologist Mark Cochrane warned that MODIS and VIIRS sensors can miss “the worst smoke events” because thick haze blocks the view, meaning underground peat fires may be “below the detection limit.” Copernicus scientists also acknowledge that their emission estimates could be conservative for the same reason.
What’s Next – Anticipated Rainfall and Ongoing Assistance
Meteorologists expect the wet season to begin in October or November, offering the “rainy session” that could finally suppress the blazes. The Japanese Chinook operation will conclude later this month, after which Indonesia plans to evaluate the effectiveness of post-2015 fire-prevention measures.
