Jakarta (Dec 2, ANN): Satellite data has shown that forest and land fires this year mostly burned idle land, peatlands or former forests, strengthening case for the mass reforestation of degraded peatlands, a research institute said on Monday (Dec 2).

“While there has been much speculation in the news that the heavy fire season has taken a toll on the country’s remaining rainforests, there was no hard evidence to support that notion, ” said David Gaveau, a landscape ecologist and research associate at the Center for International Forestry Research (CIFOR) in Bogor, Indonesia.

“We set out to determine how much land had burned and what type of land cover had been burning. This knowledge is crucial to understanding consequences and formulating solutions.”

Scientists at CIFOR analysed time-series images taken by Sentinel-2 satellites between Jan 1 and Oct 31. They performed the analysis on the Google Earth Engine.

The satellite assessment estimated that 1.64 million hectares burned over the period, across seven Indonesian provinces, including 670,000 ha (41 percent of the total burnt area) in peatlands. Fires were recorded in Central Kalimantan, Jambi, West Kalimantan, South Kalimantan, Jambi, South Sumatra and Papua.

CIFOR recorded that in 2015, in one of the worst fires in Indonesia, 2.6 million hectares were burned, emitting 1.2 billion tons of CO2, representing half of the country’s total emissions that year.

The satellite images showed that 76 percent of burnt land in 2019 was lahan terlantar (idle land). The areas were forest several years ago, but cycles of repeated burns have converted them into unproductive, degraded scrublands.

“There has been much speculation in the news that Indonesian fires are ignited by land clearing activities to establish plantations. Clearing land for this purpose only partly describes the situation. Uncontrolled fires easily propagate well beyond the intended area of burning because of large areas of flammable idle and degraded scrubland, the legacy of past deforestation, ” CIFOR statement said. - The Jakarta Post/ANN
