Mining operations are governed by a series of regulations that have been passed by the Indonesian Ministry of Energy and Mineral Resources, Ministry of Forestry, and Ministry of Environment. Among other things, these regulations spell out how concession lands need to be rehabilitated following the cessation of mining operations. While, a small number of companies comply with these environmental regulations, a much larger number fail to meet their regulatory obligations entirely. This situation is having very detrimental environmental and social consequences in the region, as tens of thousands of hectares of mined land are simply abandoned with little, if any, rehabilitation. The problem of post mining land in Indonesia is quite difficult to solve. Post-mining land is considered marginal land that can’t be utilized. One of the reasons for the poor quality of post-mining rehabilitation is the lack of technical capacity. However, if everyone is just blaming, the post-mining land will be abandoned and unused. Most coal mine companies, particularly the small and medium sized ones, lack knowledge about best-practices, even though there are some very good examples of successful mine rehabilitation in East Kalimantan.
