Thick smoke is rolling across Borneo again. Satellite images show hundreds of fire hotspots scattered across Kalimantan, the Indonesian portion of the world's third-largest island. Residential areas are choking on haze. Flight schedules are disrupted. And the smoke doesn't respect borders — it's drifting into Malaysia and Singapore, triggering air quality alerts and diplomatic tensions.

Indonesia's government and media outlets have been quick to point fingers at El Niño, the periodic climate pattern that brings drought conditions to Southeast Asia. It's a familiar narrative, one that gets dusted off every few years when the fires return. El Niño makes the forests drier, the reasoning goes, so fires spread more easily.

But that explanation is only half the story — and arguably the less important half.

The Inconvenient Truth About "Natural" Fires

El Niño does create conditions that make fires more likely to spread. During El Niño years, rainfall drops and vegetation dries out, turning forests into tinderboxes. But here's what the climate pattern doesn't do: it doesn't light the match.

The overwhelming majority of fires in Kalimantan aren't accidental, and they're not natural. They're deliberately set by people clearing land for agriculture — primarily for palm oil plantations and pulp wood operations. Burning is the cheapest and fastest way to clear forest and peatland. You don't need expensive machinery or large labor crews. You just need fire.

According to research from Indonesian environmental organizations, more than 90% of the fires during previous major burning seasons could be traced back to land clearing activities. The pattern is consistent: fires cluster on recently deforested areas, along plantation boundaries, and on degraded peatlands that companies are preparing for development.

Why Burning Persists

If everyone knows burning causes these catastrophic haze events, why does it keep happening? The answer is depressingly simple: the economic incentives haven't changed.

For small-scale farmers and large plantation companies alike, the cost-benefit calculation favors burning. The fines for illegal burning, when they're actually enforced, are often less than the cost of legal land clearing methods. Prosecution is rare. And when fires do break out, it's notoriously difficult to prove who started them — especially once the smoke obscures everything.

Indonesia has laws against burning for land clearing. The country even has a moratorium on new permits for peatland development, implemented after the devastating 2015 fires that caused an estimated $16 billion in economic losses. But enforcement remains patchy, especially in remote areas where monitoring is difficult and local officials may have financial stakes in plantation development.

There's also a timing issue. Companies and farmers often wait for dry conditions — exactly the kind El Niño brings — to set their fires, because the flames spread more effectively and do a more thorough clearing job. So El Niño doesn't cause the fires; it creates the optimal conditions for the fires that people were planning to set anyway.

The Peatland Problem

Borneo's peatlands make the fire situation particularly dangerous. Peat is partially decomposed organic matter that accumulates in waterlogged conditions over thousands of years. When it's drained for agriculture, it becomes incredibly flammable.

Worse, peat fires burn underground, smoldering for weeks or months. They're nearly impossible to extinguish completely and they produce enormous amounts of smoke. A relatively small peat fire can generate more smoke than a much larger forest fire.

Peatlands also store massive amounts of carbon. When they burn, they release decades or centuries worth of accumulated carbon into the atmosphere in a matter of weeks. The 2015 fires released more greenhouse gases in a few months than Germany's entire annual emissions.

What Would Actually Help

The solutions aren't mysterious. Other countries in the region have dramatically reduced agricultural burning through a combination of strict enforcement, real-time satellite monitoring, and economic incentives for alternative clearing methods.

Malaysia's Sarawak state, which shares Borneo with Indonesia, has reduced fire incidents by more than 80% since 2005 through aggressive enforcement and public awareness campaigns. Companies caught burning face not just fines but loss of their operating licenses.

Indonesia has the technology to do the same. The country has access to the same satellite monitoring systems. It has environmental laws on the books. What's been lacking is the political will to enforce them consistently, especially when enforcement might disrupt economically important plantation operations.

Some Indonesian provinces have experimented with "fire-free village" programs that provide communities with equipment and training for mechanical land clearing, along with financial incentives for staying fire-free. These programs show promise, but they're small-scale and underfunded.

The Cycle Continues

As smoke from Kalimantan once again blankets the region, the familiar pattern is repeating. Government officials express concern. Neighboring countries lodge diplomatic protests. Media coverage spikes. And El Niño gets the blame.

But when the rains return and the smoke clears, the underlying incentives will remain unchanged. The peatlands will still be drained. The plantations will still expand. And a few years from now, when conditions are dry again, Borneo will burn.

The question isn't whether El Niño contributes to fire conditions. It does. The question is whether we're willing to address the human decisions and economic structures that ensure those conditions get exploited. Until we do, blaming the weather is just another form of smoke screen.
