Indonesia’s ongoing battle with wildfires has triggered a regional toxic haze crisis, severely curtailing international disaster response efforts as thick smog grounds firefighting aircraft in Borneo, according to officials.
Smog Grounds Japanese Water-Bombing Helicopters in West Kalimantan
Around 350 members of Japan’s Self-Defense Forces arrived in Borneo’s hard-hit West Kalimantan province last week alongside three helicopters to assist local firefighting operations, public affairs officer Takeshi Koga told AFP. While their water-bombing mission eventually started on Wednesday, subsequent flights faced immediate disruptions due to hazardous atmospheric conditions. Thursday flights were entirely cancelled because poor visibility reduced the range of sight to less than three kilometers, or 1.9 miles, according to Koga.
The deployment marks the first known overseas firefighting operation carried out by the Japan Self-Defense Forces. A Japanese military transport ship docked in Borneo on Thursday carrying 300 crew members, landing ship JS Kunisaki, and three CH-47 helicopters. Col. Syunji Nakahara, commander of the disaster relief activities, stated at a port in Mempawah district that the mission aims to learn from the Indonesian military’s operational experience and coordinate closely to help residents resume stable lives quickly.
Escalating Wildfires and Regional Environmental Impact
Indonesia regularly faces forest and land fires during the dry season, which spans from July to October. However, blazes this year are notably severe due to an intensifying El Niño climate phenomenon expected to be the strongest since comparable records began four decades ago, alongside climate change, decades of forest degradation, and slash-and-burn land-clearing practices that alter naturally fire-resistant landscapes, according to AFP.
The resulting toxic haze and smoke have drifted far beyond Indonesia’s borders, impacting public health in neighboring Malaysia and Singapore, and stretching more than 800 kilometers away to the Philippines. The smoke breached Malaysia’s emergency-level threshold for air pollution, prompting authorities to declare an emergency in a town within Sarawak state on Borneo. In Indonesia, the pollution has forced school closures across Sumatra, affecting more than 1.4 million students nationwide.
Data Discrepancies in Burned Land Estimates
Official tallies and independent satellite tracking projects report vastly different figures regarding the total geographic area impacted by the fires this year.
| Reporting Source | Timeframe Recorded | Estimated Burned Area |
|---|---|---|
| Indonesian Forestry Ministry | January to July | More than 202,000 hectares |
| Nusantara Atlas Project | January to July | Close to 300,000 hectares |
| Nusantara Atlas Project | Including August estimates | Nearly 896,000 hectares |
To supplement local response teams accessing remote terrain, Indonesian authorities have escalated containment operations by accepting aircraft support from international partners, including the United States, Russia, Australia, Canada, and Ukraine, alongside Japan.
Did you know?
The land area burned in Indonesia between January and July—recorded at over 202,000 hectares by the Forestry Ministry—is nearly three times Singapore’s size.
Frequently Asked Questions
Why did Japan deploy military forces to Indonesia?
Around 350 members of the Japan Self-Defense Forces arrived in West Kalimantan aboard landing ship JS Kunisaki with three CH-47 helicopters to assist Indonesian authorities with aerial firefighting efforts and reach difficult terrain, according to AFP.
How has the weather affected the firefighting response?
Thick smog and low visibility reduced the range of sight to less than three kilometers, forcing officials to cancel scheduled water-bombing flights on Thursday, according to public affairs officer Takeshi Koga.
Which countries are affected by the Indonesian wildfire smoke?
The toxic haze has blanketed parts of Indonesia, Malaysia, and Singapore, and drifted as far away as the Philippines, according to AFP.
What is causing the severity of the current wildfire season?
Experts point to an intensifying El Niño climate phenomenon—expected to be the strongest in four decades—combined with climate change, forest degradation, and traditional slash-and-burn land-clearing practices, according to AFP.
