Sustainable food consumption and production in a resource-constrained world

“By 2050 the world’s population will reach 9.2 billion (...). Nearly all of this population increase will occur in developing countries. (...) about 70 percent of the world’s population will be urban (...). Income levels will be many multiples of what they are now. In order to feed this larger, more urban and richer population, food production (net of food used for biofuels) must increase by 70 percent.”
