<p>Indonesia has ca. 20-27 Mha of peatlands, which function as one of the world’s carbon sinks, since a large amount of carbon is fixed within peat and swamp forests. In recent years, peat swamp forest wildfires have occurred during every El Nino dry season in Central Kalimantan, Indonesia, resulting in the emission of a large amount of carbon dioxide. In this study, we derived peatland ground surface subsidence maps, which can be used as fire hazard maps, using 5 time-series scenes of ALOS-2/PALSAR-2 SAR image data taken between April 2015 and October 2016.</p>
