Asian peat fires add to warming
By Paul Rincon
BBC News science reporter

Burning peatland, RGS
The fires can rage out of control during dry periods
The destruction of tropical peatlands is contributing significantly to global warming, according to a study.

Peatlands in South-East Asia are being burnt in fires started with the intention to clear forest, but in dry periods they can rage out of control.

This can free vast amounts of carbon dioxide into the atmosphere, Dr Susan Page of Leicester University, UK, said.

The peatlands, which contain up to 21% of global land-based stores of carbon, could be destroyed by 2040, she added.


Where you've got large-scale drainage of the peatland and clearance of the forest, the peat is far more susceptible to igniting.

It has been calculated that in 1997, 2.67 billion tonnes of the greenhouse gas carbon dioxide were released through burning of these peatlands. This is equivalent to 40% of one year's global fossil fuel combustion, Dr Page says.

That year was unusually high, however; the intermediate estimate is one billion tonnes, about 15% of fossil fuel combustion for a year.

Forgotten resource

Tropical peatlands are spread across numerous islands in South-East Asia, including Borneo, Sumatra and Papua. The peat is found in lowland areas, can exceed 10m in thickness and has a high carbon content of about 60%.
