A green evolution:Cereal production tripled in Ethiopia: The Economist

NOT so long ago Jean Pierre Nzabahimana planted his fields on a hillside in western Rwanda by scattering seed held back from the last harvest. The seedlings grew up in clumps: Mr Nzabahimana, a lean, muscular man, uses his hands to convey a vaguely bushy shape. Harvesting them was not too difficult, since they did not produce much.

This year the field nearest to his house has been cultivated with military precision. In February he harvested a good crop of maize (corn, to Americans) from plants that grew in disciplined lines, separated by precise distances which Mr Nzabahimana can recite. He then planted climbing beans in the same field. On this and on four other fields that add up to about half a hectare (one and a quarter acres) Mr Nzabahimana now grows enough to enable him to afford meat twice a month. He owns a cow and has about 180,000 Rwandan francs ($230) in the bank. Although he remains poor by any measure, he has entered the class of poor dreamers. Perhaps he will build a shop in the village, he says. Hopefully one of his four children will become a driver or a mechanic.Read more: The economist
