Analysis of the most recent 10-year periods (2002 to 2011) of MODIS hotspots data (fires) and precipitation in Palang- karaya and Pontianak was carried out to identify seasonal and spatial fire occurrence in Kalimantan under El Niño con- ditions, and to asses future forest condition in Kalimantan. Most data was tallied every 10-day to analyze seasonal and spatial fire occurrence. Seasonal and spatial analysis results for severe fire years, namely 2006 and 2009, under El Niño conditions were as follows: the severest fire incidents for whole Kalimantan occurred in October in 2006 under the dri- est conditions in both Palangkaraya and Pontianak. The severest fires for the Mega Rice Project (MRP) area and its vi- cinity occurred in late September in 2009 under the driest conditions for Palangkaraya. Fire activities in the last 10-year in south Central Kalimantan were severe than other areas in Kalimantan. This may be explained by different dry condi- tions of peat. Namely, the peat in the southern part of Central Kalimantan could become dryer under the relatively longer dry season (about 3-month) compared with other areas (dry season in West Kalimantan is only 2/3-month). One of spatial analysis results clearly showed a so-called a fire belt shape arising from severe fires that occurred mainly on the southern coastal peatlands from West to Central Kalimantan in mid October in 2006.
