The air in Borneo doesn't smell like wood smoke. It smells like a chemical plant burning in slow motion. When Dwi Sujatmoko walks out onto the smouldering peatlands, his eyes water instantly and his lungs ache from microparticles of ancient carbon. He isn't wearing a military-grade respirator or riding in a million-dollar air tanker. He has a hand shovel, a rusty cart, and a small portable pump.
He is one of thousands of local volunteers—many from the indigenous Dayak and Banjar communities—holding the line against a subterranean catastrophe. Read more on a connected topic: this related article.
Right now, an intense Super El Niño cycle has turned Indonesian Borneo and Sumatra into a tinderbox. Over 200,000 hectares of forest and farmland have scorched since July. A toxic amber haze has choked out the skies, drifting across international borders to blanket Singapore, Kuala Lumpur, and Manila.
The Subterranean Threat of Peatland Wildfires
If you think a wildfire ends when the flames stop dancing in the tree canopy, you’ve never seen a tropical peatland burn. Additional analysis by USA Today delves into related views on the subject.
Normal forests burn wood and brush. Peatlands burn time. Layer upon layer of partially decayed organic matter, accumulated over thousands of years in waterlogged swamp conditions, dries out when drained or exposed to extreme heat. Once that subterranean peat catches fire, it burns underground. It's invisible, stubborn, and nearly impossible to drown out with surface water alone.
Dr Nisa Novita of the conservation group YKAN points out the obvious danger: these swamp ecosystems store massive density of carbon. When they dry out and ignite, they don't just produce smoke—they detonate a carbon bomb. Millions of tonnes of carbon dioxide, carbon monoxide, and methane erupt directly into the atmosphere, accelerating the exact global heating that made the drought so brutal in the first place.
Why Official Aid Always Arrives Too Late
You’d expect a regional crisis affecting tens of millions of people to trigger an immediate, heavy-handed state response. The reality on the ground is messier.
By the time national government budgets allocate funds, commercial fire squads mobilize, and heavy machinery gets barged up shallow jungle rivers, the fires have already burrowed deep into the peat beds. Bureaucracy moves at the speed of paperwork. The fires move at the speed of oxygen and dry root systems.
That leaves local volunteers acting as the first, middle, and last line of defense.
Dayak and Banjar volunteers know these swamp labyrinths better than any satellite map. They dig trench lines by hand to isolate burning peat blocks. They haul water through knee-deep muck under temperatures that cook the air around them. They do this without hazard pay, modern insurance, or guaranteed equipment replacement.
The Regional Haze You Can't Ignore
This isn't a localized tragedy you can safely scroll past. Southeast Asian haze events have a long history of shutting down schools, grounding flights, and spiking hospital admissions for acute respiratory infections. When Borneo coughs, Southeast Asia catches pneumonia.
Yet the economic incentive structures driving the initial drying of these peatlands—largely historical land clearance for palm oil and pulp plantations—rarely face the same immediate pressure as the firefighters in the trenches. Draining a swamp is cheap on a corporate spreadsheet. Putting out the resulting underground inferno with a hand pump costs human sweat and lungs.
What Needs to Change Right Now
We have to stop treating volunteer fire brigades as romantic local heroes and start funding them as frontline climate infrastructure.
If governments and international climate funds are serious about keeping carbon in the ground, the money needs to bypass slow national ministries and land directly in the hands of indigenous and community-led protection units. Stop waiting for the next Super El Niño to expose how fragile our regional response systems really are.
Support local peatland restoration initiatives directly, pressure multinational supply chains to abandon drained peat concessions, and demand that climate finance actually reaches the people standing in the smoke.
