Southeast Asia continues to grapple with the recurring problem of transboundary haze pollution, as dense smoke from widespread fires in Indonesia affects air quality in Malaysia, Singapore, southern Thailand, and Indonesia itself. The fires, primarily burning in Sumatra and Kalimantan, have resulted in unhealthy to hazardous air conditions, prompting school closures and increased respiratory cases, particularly among vulnerable populations such as children and the elderly.

Despite efforts by the Association of Southeast Asian Nations (ASEAN) to address the issue, the crisis has persisted for decades. ASEAN initially responded by signing the Agreement on Transboundary Haze Pollution in 2002, committing member states to cooperative measures to eliminate haze. Subsequent initiatives included the establishment of monitoring systems and the development of roadmaps targeting a haze-free regional environment first by 2020, and later by 2030. However, these plans have yet to achieve their intended outcomes.

On August 26, this year, the ASEAN Specialized Meteorological Centre issued its highest regional haze alert amid worsening conditions. In response, member countries coordinated meetings, issued statements, and discussed cloud-seeding as a potential mitigation method. Assistance offers were extended to Indonesia, where government forces are actively combating fires using troop deployments, water resources, aerial firefighting, and direct coordination by the president.

Experts and observers point to underlying causes such as weak enforcement of environmental regulations, economic incentives that encourage land clearing through burning, and a regional reluctance to intervene decisively in the affairs of neighboring countries. This culture of non-interference often results in the conflict being treated as a purely domestic problem for Indonesia, despite its transboundary impact. Critics argue that current approaches focus too much on reactive measures and diplomacy rather than proactive prevention and accountability.

The coordinating body established to operationalize the 2002 agreement remains incomplete and underpowered, limiting its effectiveness. Local populations affected by the haze are calling for stronger enforcement mechanisms that can hold responsible parties accountable and for greater transparency regarding fire origins. They emphasize the need for tangible prevention strategies rather than periodic diplomatic communiqués.

With strong El Niño weather patterns contributing to dry conditions that facilitate fires, the region faces a recurrent cycle that repeatedly exposes the gaps in regional management. While offers of assistance and dialogue have improved relative to past years, many stress that only decisive political will and comprehensive enforcement can break the cycle and reduce the persistent health and environmental hazards posed by the haze.
