Perkembangan Pemetaan dan Distribusi Lahan Gambut di Indonesia
In the distribution of peatlands, spatial data becomes increasingly important in line with increasing interest of various parties regarding the function of peatlands. Peatland maps have a strategic meaning in the planning of peatland utilization for production and for conservation. Peatlands also play an important role in national action plans for GHG emissions reduction (RAN-GRK) and as "activity data" in GHG emissions calculations.
Current estimates of Indonesia's peatlands are about 14.9 million hectares (map scale 1: 250,000), mainly spread throughout the islands of Sumatra, Kalimantan and Papua, with varying thicknesses ranging from 1-10 meters and an average of about 3 meters. Peatland mapping is faced with limited survey data due to low accessibility to some peatlands, especially those in the inner regions of Papua and Kalimantan. Therefore, the "peatland map" is a dynamic document, which needs to be updated according to advances in remote sensing technology and collected survey data. Mapping at the provincial and district levels is also important to support utilization and conservation plans in the area. This poses a challenge to the dominant areas of peatlands, but no peat map with higher level of detail is available e.g. peatlands in North Sumatra, South Sumatra, Central Kalimantan and Papua.
