Indonesia has approximately 14 Mha of degraded lands. These lands have potential for growing biofuel species to meet needs for energy security, income generation and land restoration. One promising species, Calophyllum inophyllum, is suitable for growing on 5.7 Mha of degraded land in Indonesia, and could contribute to green energy production and restoration of this degraded land. During its early growth stage, the species can grow by up to one metre per year and is tolerant to harsh environmental conditions. Its seeds provide high levels of non-edible oil, thus making it ideal for biodiesel production. In addition, waste and by-products from the biodiesel production process can be used as raw materials in the pharmaceuticals and cosmetics industries, and as compost for soil enrichment. Growing various cash crops together with Calophyllum inophyllum in agroforestry systems can provide extra income for farmers, thus creating added value for Calophyllum inophyllum cultivation.
