The number of blazes in Indonesia’s rainforests has jumped sharply, satellite data showed Thursday, spreading smog across Southeast Asia and adding to concerns about the impact of increasing wildfire outbreaks worldwide on global warming.
Illegal blazes to clear land for agricultural plantations have been raging on Sumatra and Borneo islands, with Indonesia deploying water-bombing helicopters and thousands of security forces to tackle them.
It is just the latest such outbreak worldwide — huge blazes have torn through the Amazon in South America while bushfires are sweeping across eastern Australia in an unusually ferocious and early start to the wildfire season.
Indonesia’s forest fires are an annual problem but have been worsened this year by particularly dry weather, and in recent days sent toxic smog floating over Malaysia and triggered a diplomatic row.
The number of “hotspots” — areas of intense heat detected by satellite which indicate a high chance of fire — jumped sharply in Indonesia on Wednesday, according to the Singapore-based ASEAN Specialised Meteorological Centre.
There were 1,619 hotspots detected on the Indonesian part of Borneo and Sumatra up from 861 a day earlier, according to a tally from the centre, which monitors forest fires and smog outbreaks.
Kiki Taufik, a forests campaigner with Greenpeace in Indonesia, told AFP there has been little rain in the past fortnight, particularly on Indonesian Borneo which saw the sharpest increase in hotspots.
Borneo is shared between Indonesia, Malaysia and Brunei.
