Eco-crisis: The devastation of Borneo's forests

Warning: Do not look at this map if you don't want to feel depressed. 

The image shows how much of Borneo's biodiversity-rich forests have been destroyed or degraded in the last four decades -- and it's enough to ruin anybody's breakfast.

From 1973 to 2010, the tropical rainforests of Borneo have been razed twice as fast as those elsewhere on the planet, according to a freely available study that just appeared in PLoS One.

In the paper, David Gaveau, Sean Sloan, and colleagues analyzed Landsat imagery to see how much of Borneo's mega-diversity forests have been cleared, burned, or degraded by industrial logging. 

It's not a pretty picture -- as also detailed here in the leading environmental website Mongabay.

In 1973, more than three-quarters of Borneo was blanketed by native forest, much of which was undisturbed or little disturbed, according to the study.

By 2010 nearly 17 million hectares of the forest -- an area larger than England, Wales, and Northern Ireland combined -- had vanished.

Echoing an earlier study that spanned all of Indonesia, industrial logging, oil palm, and wood-pulp plantations were apparently the biggest culprits, along with slash-and-burn farming.

Increasingly, large expanses of Borneo are dominated by selectively logged native forests.  As highlighted previously here at ALERT, these forests still retain considerable biodiversity and carbon, but are intensely vulnerable to being cleared or burned.

The challenge at hand for Borneo is clear, the study concludes.

It's vital to slow forest destruction, by safeguarding existing protected areas and especially by defending the selectively logged forests that now increasingly dominate the island.
