Indonesia faces severe wildfire haze crisis affecting multiple provinces and neighboring countries

The wildfire haze crisis in Indonesia is a significant environmental disaster that can disrupt regional economies and public health.

• Wildfires intensified in Indonesia's Kalimantan and Sumatra provinces, affecting air quality and health across 10 provinces.
• Health services overwhelmed with over 5,000 weekly emergency room visits for respiratory issues, a tenfold increase since earlier this year.
• Regional haze impacts extend to Malaysia and Brunei, prompting cross-border health alerts and emergency responses.

• Annual dry-season fires in Indonesia are exacerbated by El Niño cycles, which prolong drought conditions and increase fire risks.
• Land-clearing practices using slash-and-burn methods contribute significantly to the frequency and intensity of these wildfires.
• The 2026 'super El Niño' has intensified conditions, leading to a dramatic increase in burned areas compared to non-El Niño years.

The wildfire haze crisis in Indonesia is a complex interplay of environmental factors, human activities, and systemic challenges. The ongoing El Niño phenomenon has created prolonged dry conditions, which are ideal for wildfires. This year's 'super El Niño' has intensified these conditions, leading to a significant increase in fire hotspots across the archipelago.

Land-clearing practices, particularly for palm oil plantations, have long been a contentious issue in Indonesia. Farmers often resort to slash-and-burn techniques to clear land quickly and cheaply. However, these methods not only contribute to the immediate outbreak of fires but also create long-term environmental degradation, particularly in peatland areas that are highly susceptible to burning.

As fires spread, they have burned tens of thousands of hectares, with over 286,000 hectares reported as burned since January 2026. The Indonesian government, under President Prabowo Subianto, has responded by revoking permits and arresting individuals linked to arson. Despite these efforts, the scale of the crisis has overwhelmed local firefighting resources, leading to the deployment of aerial firefighting operations and cloud-seeding initiatives to induce rain.

The health impacts are severe. Residents in affected areas are experiencing respiratory issues, with emergency room visits for respiratory symptoms skyrocketing from 500 per week to over 5,000 in West Kalimantan alone since July. Schools have shifted to online learning to protect children from hazardous air quality, which has dropped visibility to as low as 10 meters in some regions.

The crisis has also prompted regional responses, with Malaysia coordinating cloud-seeding operations to mitigate the haze's effects. However, the long-term implications of these wildfires extend beyond immediate health concerns; they threaten regional stability and economic resilience, particularly for sectors reliant on agriculture and natural resources.

• Local residents in affected provinces face immediate health risks and disruptions to daily life.
• Healthcare providers are overwhelmed with increased patient loads due to respiratory issues.
• Agricultural sectors may experience disruptions in productivity and supply chains due to health impacts and environmental degradation.
• Regional governments in Malaysia and Brunei are forced to respond to cross-border haze impacts, straining resources.

• Weather patterns: Monitor rainfall forecasts and El Niño developments, as these will influence fire risks and haze conditions.
• Government actions: Watch for further regulatory changes in land-clearing practices and enforcement actions against illegal burning.
• Health data: Keep an eye on emergency room visit trends and public health responses in Indonesia and neighboring countries.
