Escalating Wildfires and Transboundary Haze (September 2026)
Since the start of the year, Indonesia’s islands of Borneo and Sumatra have been engulfed by forest and peat-land fires. Independent monitoring by Nusantara Atlas recorded 734,000 hotspots as of late September, more than 30 % above the 2019 peak season. The fires have burned at least 895,000 ha, and smoke has drifted across Malaysia, Singapore, Brunei, the Philippines and Vietnam, creating “hazardous” AQI readings that exceed 300 in several cities.
Background & Context
Indonesia’s dry season runs from July to October. This year a “super” El Niño has intensified drought, and decades of slash-and-burn clearing on drained peatlands have left the soil highly flammable. Landscape ecologist David Gaveau notes that peat fires can burn underground for weeks, resurfacing repeatedly.
Data & Statistics
- Respiratory cases: Health-ministry data show 113,336 acute respiratory infections by 9 September, up from 50,891 on 1 September.
- Air-quality: Sampit (central Kalimantan) recorded an AQI of 1,142 on 10 September; Kuching (Malaysia) logged 157 the same day.
- Emissions: Fire Emissions Watch measured 19.7 million metric tons of fire emissions in the first week of September, over one-third of the global total.
- Economic loss: CELIOS estimated fire-related losses between 39.29 trillion and 123.1 trillion rupiah for January–August.
Official Statements & Responses
Indonesia’s Cabinet Secretary Teddy Indra Wijaya emphasized that “all forces continue to move” in a coordinated effort that includes 64 aircraft and 54,000 personnel deployed to Borneo and Sumatra. President Prabowo Subianto pledged tougher penalties, describing the fires as “ecological terrorism” and ordering revocation of licences for responsible companies.
Japan’s Ministry of Defense announced the deployment of a CH-47 Chinook aboard JS Kunisaki (arrived 21 September), marking the first overseas firefighting operation by Japan’s Self-Defense Forces. Malaysia contributed three helicopters, an aircraft and 52 personnel; Japan also sent additional helicopters and a fire-fighting force.
Criticism & Opposition
Political and legal campaigner Fajri Fadhillah argued that ASEAN’s 2003 haze-pollution agreement is insufficient, calling for “mutual accountability” among member states.
On-the-Ground Reports
Local residents describe daily life under a “toxic smog” that forces schools to close and hospitals to fill. In Malaysia, video editor Mohamad Haazim reported that the haze “deeply disrupted my daily routine,” confining him to indoor exercise.
Conflicting Reports & Gaps
Sources differ on the total burned area: the health ministry cites 895,657 ha, the Straitstimes says “nearly 900,000 ha,” while Eco-business mentions “more than 895,000 ha.” The Kuwait Times reports 202,000 ha burned between January and July, whereas Nusantara Atlas estimates close to 300,000 ha for the same period, a discrepancy of roughly 100,000 ha.
What’s Next
Forestry Minister Antoni indicated that September is “the month of struggle” and that fires could peak before the rainy season begins in November. The government has pledged to continue water-bombing operations, expand aerial assets, and seek regional cooperation, while NGOs call for stronger enforcement of peat-land protection and faster legal action against repeat offenders.
