Just growing more food won't help to feed the world | Richard Ewbank

Rush to increase production has caused catastrophic environmental degradation. We need to make agriculture climate-resilient and more efficient

The World Bank's view that we need to grow 50% more food by 2050 to feed 9 billion people, while finding ways to reduce carbon emissions from agriculture at the same time, ignores one very simple fact - we already grow enough food for 10 billion people.

But a combination of storage losses after harvest, overconsumption and waste mean that some 800 million people in developing countries are malnourished.
