A Green Revolution for Africa

THE Chichewa people in Malawi have a saying: Njala ndi chilombo. It means "Hunger is a beast". Today, the beast is rampaging around the world and particularly Africa, where shortage of food threatens to undo recent economic and political gains. Climate change is partly to blame. But there is another less well recognised cause: long-term neglect has left African agriculture in a woefully inadequate state.
