Malaysia and Indonesia launch joint cloud-seeding to battle wildfire haze crisis

Indonesia has granted Malaysia permission to conduct joint cloud-seeding operations across their shared border as wildfires on Sumatra and Kalimantan continue to pump thick haze into the region.

The transboundary pollution has forced the closure of nearly 600 schools in Malaysia and reduced visibility so severely that Kuala Lumpur's Petronas Twin Towers, normally visible for miles, have disappeared behind a grey shroud.

Coordinated airspace operations

Malaysia's disaster management agency and meteorological department are now scheduling cloud-seeding flights in border areas, with the Indonesian military handling coordination on the ground. Natural Resources and Environmental Sustainability Minister Arthur Joseph Kurup confirmed on Monday that 16 Malaysian locations had recorded unhealthy readings on the air pollutant index as of 10am on August 26.

The wildfires driving the crisis are burning across Indonesia's Sumatra island and Kalimantan, the Indonesian portion of Borneo that Malaysia shares. Authorities from both nations are coordinating response operations along the Bornean frontier.

Relief versus prevention

While the joint cloud-seeding effort offers immediate relief from the choking conditions, experts caution that fire prevention at the source remains the fundamental challenge. The haze episodes, a recurring regional crisis, stem from slash-and-burn land clearing practices that ignite peatlands and forests, sending plumes of smoke across Southeast Asia when weather patterns shift.

The school closures and air quality emergency underscore how quickly the situation has deteriorated, turning what is typically a seasonal environmental nuisance into a public health crisis that disrupts daily life across multiple Malaysian states.
