The dead of the dry season, intensified by a super‑El Niño, has set Borneo’s peatlands ablaze. In 2015, similar conditions sparked the largest fire season on record, and this year’s blaze is already eclipsing that scale. Satellite data shows the fires have burned roughly 900,000 hectares, nearly nine times the size of Singapore.
Air‑quality readings have spiked, with some parts of Borneo recording index values above 1,000, a threshold that triggers emergency health advisories. Across Singapore, the one‑hour PM2.5 concentration hit 284 µg/m³ on Wednesday, the first time the national agency has flagged a “very high” level this year.
Health officials in Indonesia report 283,270 respiratory‑related illnesses linked to the smoke, more than double the 113,336 cases recorded in early September. Transport disruptions have compounded the crisis: 2,000 flights were grounded and several schools in Indonesia, East Timor, and Malaysian states were forced to close.
Jakarta says it has committed 60,000 personnel and 50 aircraft to firefighting, and it plans to add 5,000 forest rangers to its ranks. The ministry also announced a peatland rehabilitation program and threatened legal action against 223 individuals and nine companies suspected of illegal slash‑and‑burn.
Critics argue that the government’s refusal to declare a national disaster has stalled aid mobilization. Malaysia and Singapore have offered assistance, but Jakarta declined, citing sovereignty concerns, a move that has inflamed regional tensions.
Experts warn that the fires are unlikely to be contained until the region receives sustained monsoon rains, projected to arrive in early November. Meanwhile, the government has convened an emergency task force to coordinate cross‑border clean‑up operations.
