World food production must increase 70% by 2050 to cover a projected human population of 9.1 billion, says the UN Food and Agricultural Organization (FAO). The FAO report anticipates nearly all the population growth to occur in developing countries.

“Around 70% of the world population will live in cities or urban areas by 2050, up from 49% today,” the document says.

Food demand is expected to grow as a result of rising incomes, as well. The paper says cereal production will have to increase by 1 billion tons and meat production by more than 200 million tons to reach a total of 470 million tons that will be needed in 2050.
