The farmers of Makeni, in central Sierra Leone, signed the contract with their thumbs. In exchange for promises of 2,000 jobs, and reassurances that the bolis (swamps where rice is grown) would not be drained, they approved a deal granting a Swiss company a 50-year lease on 40,000 hectares of land to grow biofuels for Europe. Three years later 50 new jobs exist, irrigation has damaged the bolis and such development as there has been has come 'at the social, environmental and economic expense of local communities', says Elisa Da Vià of Cornell University in this article from The Economist about land grabbing.
