This year, for the sixth time in 11 years, the world will consume more food than it produces, largely because of extreme weather in the US and other major food-exporting countries. Oxfam last week said that the price of key staples, including wheat and rice, may double in the next 20 years, threatening disastrous consequences for poor people who spend a large proportion of their income on food. In 2012, according to the FAO, food prices are already at close to record levels, having risen 1.4% in September following an increase of 6% in July.
