We know that most of the world’s hungry live in the developing nations in the South. They are hungry because they cannot afford to buy food or grow it themselves, usually because of poverty, but also due to conflict, poor infrastructure, poor agricultural practices, and the over-exploitation of the environment, among other things. They are also hungry because much of their agricultural production is focused on generating food and livestock feed to supply Western markets. Recent price rises caused by harvest failures, commodity speculation, and the diversion of grain to produce biofuels over recent years have hardly helped matters (see for example Tom Philpott’s excellent blog on the horrendous impact U.S. biofuels policy is having on global food prices – and hunger).
