This report examines the extent and nature of artisanal and small scale gold mining (ASGM) in Central Kalimantan, Indonesia. In the observed areas, landscape change analysis reveals general trends of decreasing dense vegetation/forest, substantial growth of agriculture, and varying degrees of increase for mine affected areas as well as exposed soils. The results of ASGM characterization indicate a variety of techniques employed including dredging, open pit mining, and rock mining. Nevertheless, evidence of active ASGM exploitation is more prevalent in some areas than others. This attests to the dynamic nature of ASGM in the Central Kalimantan region, which may be attributable to the continual discovery of new opportunities for mining, as well as the fact that ASGM is illegal in many of the areas where it occurs.
