Indonesia is grappling with a public‑health crisis as a relentless haze, generated by extensive forest and peatland fires, has driven more than 175,000 people to seek medical care for respiratory problems since August. The situation underscores the intertwined challenges of climate‑driven weather patterns, land‑use practices, and the capacity of emergency services to respond.

Scale of the health impact

According to the health ministry, the recorded cases range from mild coughs to severe pneumonia, with over 40,000 of those affected being toddlers. The number of wildfire‑related respiratory illnesses more than doubled in September, rising from 50,891 on 1 September to 113,336 by 9 September, before climbing to the current total of roughly 175,000.

Firefighting effort and its limits

Indonesia has mobilised more than 54,000 officials and dozens of jets for water‑bombing missions across the islands of Borneo and Sumatra. Despite this large deployment, the vast terrain and especially the peatland conditions hinder containment. Cabinet Secretary Teddy Indra Wijaya affirmed that “all forces continue to move” to extinguish the fires and protect the public.

Environmental backdrop

The fires are being amplified by a strong El Niño event, dubbed “Godzilla,” which has created unusually dry conditions. Independent monitoring by Nusantara Atlas identified about 734,000 hotspots, a figure over 30 % higher than the 2019 season, one of Indonesia’s worst wildfire years. Since January, at least 895,657 hectares—almost six times the size of Greater London—have burned.

Broader consequences

Beyond human health, the haze has disrupted education, forced school closures, and threatened wildlife, including critically endangered orangutans. A recent incident in West Kalimantan saw an orangutan die after being rescued with emergency treatment for hypoxia.

Legal and political response

Indigenous groups and civil‑society organisations in West Kalimantan have filed a class‑action suit against the central and local governments, alleging deliberate negligence in addressing the fires. Their lawyer, Glorio Sanen, argued that the recurring pattern of haze demonstrates prior knowledge of the risks.

Mitigation attempts

Cloud‑seeding operations have been conducted, sometimes in partnership with Japan’s Self‑Defense Forces. While meteorologists debate the efficacy of seeding, the practice aims to stimulate rain over fire‑affected zones. Neighboring Malaysia’s Sarawak state also launched a five‑day cloud‑seeding effort, partly to raise water levels in hydropower dams ahead of an anticipated dry spell in October.

Regional spread of the haze

The smog has travelled beyond Indonesia, reaching parts of the Philippines, where officials advise residents to stay indoors, and Singapore, where daily haze advisories are now routine.

Analysis

Health burden: The rapid rise in respiratory cases, especially among children, signals acute exposure to particulate matter well above safe thresholds. The data suggest that the haze is not a transient inconvenience but a sustained health emergency.

Fire management challenges: The combination of peatland fires, which burn underground, and the sheer scale of the affected area overwhelms conventional firefighting tactics. Water‑bombing alone cannot reach subterranean peat fires, highlighting the need for alternative strategies.

Policy implications: The legal action by indigenous groups reflects growing frustration with perceived governmental inaction. It may pressure policymakers to adopt stricter land‑use regulations and invest in preventive measures, such as better monitoring and community‑based fire management.

Uncertainty

While the health ministry provides case numbers, the exact proportion of those illnesses directly attributable to haze versus other seasonal factors remains unclear. Additionally, the long‑term effectiveness of cloud‑seeding as a fire‑mitigation tool is still debated among experts.

Overall, the convergence of an extreme El Niño, extensive peatland fires, and limited firefighting capacity has created a perfect storm for public health in Indonesia. Addressing the crisis will require coordinated regional action, stronger environmental safeguards, and transparent reporting to mitigate both immediate and future risks.
