The Dutch company BioShape acquired a 50-year lease in 2006 for 81,000 ha of bio-diverse land in the Tanzanian Kilwa district to cultivate jatropha at a site located to the north of the Mavuji river, about 20km inland from Kilwa Masoko. It planned to sell biodiesel to the European Union market on the back of an EU Renewable Energy Directive that set a 10 per cent binding target for use of renewable energy in the transport sector by 2020. Huge tracts of land were cleared, much of it ecologically sensitive woodland. But one of the main investors in BioShape, Eneco Energie BV, pulled out in early 2009. In November 2009, the company ceased operations. Areas of dispute stretch back to the beginning of the project, with allegations of irregularities in the Environmental Impact Assessment. Other concerns were around food security, because people left farming to work for Bioshape, where there were complaints of long working hours and poor pay. There were also concerns about the level of compensation paid for land as payments did not meet expectations. Furthermore, there were allegations that Bioshape was more interested in the land for its timber value as timber from forests cleared was exported.
