GENEVA — World food production will have to increase by up to 100 percent by 2050 and focus on greener methods to sustain an expected 9 billion population, the U.N. said Tuesday in its annual survey of economic and social trends.
The U.N.’s annual World Economic and Social Survey called for governments to invest nearly $2 trillion a year to help small-scale farming and to reduce environmental harm.
Only a fraction of the small-investment goal has been reached so far through allocations from $20 billion in climate-change funds managed by the World Bank aimed at helping developing countries boost clean-energy technology, sustainable farming and other initiatives, the survey said.
