【 摘 要 】

Peat fire emits a large amount of carbon to the atmosphere. This emission can affect atmospheric composition and also the climate system. This paper discussed the carbon emission from the 2015 peat fire, the largest after 1997 one. Indonesian National Carbon Accounting System (INCAS) published by The Indonesian Ministry of Environment and Forestry was used to calculate the carbon emission from the peat fire. Peat fire emission factors used in the calculation for region of Sumatera and Kalimantan were selected from previous study, while for Papua's region extrapolation method was applied. Peat area burned was estimated by using Normalized Burn Ratio (NBR) based on hotspot data enquired from MODIS. The cumulative peatland area burned from July - October 2015 in Indonesia was estimated to be about 623,304 ha, where about 270,691 ha (43%), 320,756 ha (51%) and 31,857 ha (5%) were found in Sumatera, Kalimantan and Papua, respectively. By considering only the three biggest gaseous carbon compounds released by biomass burning (CO2, CO, and CH4), therefore total carbon emitted to the atmosphere during these four months peat fire was estimated to be about 0.002 Gtonnes, of which 81% was in the form of CO2; 16% CO and 2.3% CH4.
