Energy demand in Indonesia is increasing rapidly, by 43% between 2005 and 2016. Indonesia thus relies on imported fuel (27%). Around 16.8 mill ha of land in Indonesia is severely or highly severely degraded. Restoration is very costly, ranging from approximately US$250 to 3000/ha. Biofuel species such as nyamplung (Calophyllum inophyllum) could be used to restore around 5.7 million hectares, at a relatively low cost.
