Potential land for plantation of Jatropha curcas as feedstocks for biodiesel in China

摘要: As a renewable energy, biofuel has attracted great attention in China and the rest of world. Concerned with national food security, recently shifted its development priority from grain-based to non-grain-based biofuels, including forest-based biodiesel, since 2007. Jatropha curcas is one major biodiesel feedstocks. However, there rising debate on availability land for expanding areas. The overall goal this paper evaluate potential used as feedstock China. Based remote sensing data use, meteorological, soil slope, suitable environment plantation, study uses Agro Ecological Zone method considers social-economic constraints plantation China’s production region, Southwest results show that while are some lands expand areas, amount these will hardly meet government’s target curcas-based biodiesels future. may need reconsider long-term targets biodiesels.
