How to feed the world in 2050

By 2050 the world's population will reach 9.1 billion, 34 per cent higher than today. Nearly all of this population increase will occur in developing countries. Urbanization will continue at an accelerated pace, and about 70 per cent of the world's population will be urban (compared to 49 percent today). 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. Annual cereal production will need to rise to about 3 billions tonnes from 2.1 billion today and annual meat production will need to rise by over 200 million tonnes to reach 470 millon tonnes.
