La crise alimentaire, le développement durable et les biocarburants : perspectives d’avenir

Biofuels, extracted from cereals and other food crops, are attracting greater interest, especially as a substitute for fossil energy. However, the use of food products for biofuel production has been recently described as crime against humanity, since it contributes to raise the world market food pr...
