　　A new study in West Africa shows how farm irrigation systems powered by the sun can produce more food and money for villagers.The study in Benin found that solar­powered pumps are effective in supplying water，especially during the long dry season.

　　Sub­Saharan Africa is the part of the world with the least food security.The United Nations Food and Agriculture Organization estimates that more than one billion of the world’s people faced hunger last year.Around 265 million of them live south of the Sahara Desert.Lack of rainfall is one of their main causes of food shortages.
