Malaysia declares air-quality emergency as haze from Indonesian fires reaches critical level

Haze has become a recurring seasonal problem across Southeast Asia, driven primarily by forest and peat fires in Indonesia. The combustion of these lands releases thick smoke that can linger for weeks, creating visibility problems and health concerns throughout the region. The phenomenon typically peaks during the dry months, when low rainfall and prevailing winds facilitate the spread of particulate matter over large distances.

The smoke routinely crosses national borders, affecting neighboring Malaysia, Brunei and Singapore, where authorities often issue air‑quality warnings and advise the public to limit outdoor activities. The transboundary nature of the haze underscores the need for coordinated fire‑management strategies and regional cooperation to mitigate its environmental and public‑health impacts.
