Indonesia’s Peatland Fires Spark Regional Haze Crisis and Threaten New Capital

Core Event: Peatland Fires and Transboundary Haze
Since early July 2026, wildfires have engulfed Indonesia’s peatlands on Borneo and Sumatra, producing a haze that has drifted across Singapore, Malaysia, the Philippines and Brunei. The fires have carbonised roughly 200,000 hectares of forest and farmland, and satellite monitoring recorded 946 hotspots on August 31. By September 2, about 400 hectares had burned around the under-construction capital Nusantara, including 300 hectares at Bukit Suharto forest park. Air-quality indices have reached “acutely unhealthy” levels—up to 75 times WHO limits in some locations.
Background & Context
The blaze coincides with a “Super El Niño” that has deepened drought across the archipelago. Drained peatlands, a result of decades of logging, plantation expansion and canal construction since the Suharto era, become highly flammable and emit carbon dioxide continuously, even when not burning.
Data & Statistics
- Area burned: 200,000 ha total; 73,311 ha in six hardest-hit provinces; 400 ha around Nusantara.
- Hotspots: 946 detected on August 31 2026.
- Emissions: 10 % of the 2015 fire season’s total already released by early September; 57 gigatonnes of carbon emitted from Indonesia’s fires between August and September.
- Health impact: > 50,000 respiratory infections recorded by Indonesia’s Health Ministry between July and August, including 12,000 children under five.
- Air-quality indices: 780 in Palangkaraya and 593 in Pontianak.
Official Statements & Responses
Disaster-mitigation director Agus Riyanto requested cloud-seeding and water-bombing operations near Nusantara and confirmed a helicopter deployment from South Kalimantan. The disaster agency reported 53 aircraft conducting water-bombing, with additional support from Japan. Malaysia declared a state of emergency in Sarawak and suspended outdoor Independence Day celebrations; its health ministry noted a rise in asthma cases to 1,811 during the week of 23-29 August. Indonesia’s Health Ministry continues to treat tens of thousands of haze-related patients.

- “Indonesia is only about three weeks into its fire season, but we're seeing fire activity track sharply upward, similar to 2015,” — Robert Field, Columbia University researcher
Conflicting Reports & Gaps
Sources differ on the total area burned: BBC estimates 200,000 ha across Borneo, Reuters cites 73,311 ha in six provinces, and the fire-monitoring platform reports 400 ha near the new capital. No single source provides a consolidated national total, leaving the full scale of the crisis unclear. Satellite data capture surface hotspots, but underground peat fires can evade detection, suggesting official hotspot counts may understate the actual fire footprint.
What’s Next
Indonesia plans to commence cloud-seeding once atmospheric conditions permit, while water-bombing continues. Religious leaders gathered in front of the Nusantara state palace on September 4 to perform “Istisqo” prayers for rain. Officials stress that September marks the height of the El Niño season, indicating that fire-fighting and mitigation efforts will intensify throughout the month.
