Indonesia’s 2026 Forest Fires Spark Widespread Haze and Health Crisis
9/4/2026, 7:48:14 AM
Core Event
Since mid-July 2026, forest and peatland fires have raged across Kalimantan, Sumatra and West Java. The National Disaster Management Agency (BNPB) recorded 46 hotspots in West Kalimantan on September 4, burning more than 528 ha, while Central Kalimantan reported 72 hotspots covering about 739 ha. SiPongi estimates 202,011 ha burned nationwide between January and July, with July alone accounting for 95,000 ha. Hotspots in West Kalimantan rose to 7,377 by September 1, and active fires reached 104.
Background & Context
A “Super El Niño” that began in June intensified the dry season, drying peatlands and making them highly flammable. Investigations attribute most fires to deliberate burning for oil-palm and pulp-paper plantations.
Data & Statistics
- Burned area: ? 202,000 ha (Jan-Jul); ? 95,000 ha in July.
- Hotspots (Sept 1): West Kalimantan 7,377; Central Kalimantan 5,244.
- Air quality: Pontianak AQI 851; Palangkaraya AQI 675 (hazardous).
- Health: 50,891 acute respiratory infection cases in July-August; 13,500 treated for respiratory infections (Deputy Health Minister Dante Saksono Harbuwono).
- Malaysia: Asthma cases 1,811 (Aug 23-29); conjunctivitis 720.
- Philippines: “acutely unhealthy” PM2.5, >15 × WHO limits.
Health Impact
Respiratory infections surged, affecting 12,600 children under five. Smoke traveled beyond fire zones, exposing neighboring populations. In Sarawak, hazardous Air Pollutant Index readings above 300 were recorded in Kuching and Serian. Residents reported persistent coughs, throat irritation and “mini heart attacks” for infants. In the Philippines, doctors noted headaches, itchy eyes and sore throats linked to the haze.
Wildlife Impact
Thick smoke threatened endangered Bornean orangutans. YIARI treated a 20-year-old male orangutan, Sampurna, after hypoxia, and rescued a mother, Raya, and infant, Rayu, in Central Kalimantan. At least seven orangutans have been treated this year, and ash fell on enclosures at the Labanan Special Purpose Forest orangutan rehabilitation centre in East Kalimantan.
Official Statements & Responses
Forestry Minister Raja Juli Antoni warned September marks the peak of El Niño and the “real battle” to contain the blazes. Deputy Health Minister Harbuwono said roughly 5.5 million people on Borneo and Sumatra have been directly exposed to smoke. ASEAN activated a Level 3 transboundary haze alert, its highest level.
Conflicting Reports & Gaps
The Forestry Ministry’s fire-monitoring service reports 202,011 ha burned (Jan-Jul), while other outlets cite “more than 202,000 ha” without a precise figure. Hotspot counts differ slightly between agencies, reflecting challenges in detecting underground peat fires.
