Will Africa have its "green revolution"?

Mr Mushongi’s sponsors, who funded him for two years at a South African university, have a simple if ambitious aim: to follow the example of the “Green Revolution” in Asia in the 1970s, which multiplied crop yields largely through the introduction of new seed types and fertilisers. This year’s famine in east Africa, and the rising food prices on the back of the high price of oil, have heightened the urgency of the quest.
