This is the VOA Special English Development Report, from voaspecialenglish.com 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 solar-powered pumps are effective in supplying water, especially during the long dry season. Sub-Saharan 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 two hundred sixty-five million of them live south of the Sahara Desert. Lack of rainfall is one of their main causes of food shortages. Jennifer Burney from Stanford University in California led the study. The research team helped build three solar-powered drip irrigation systems in northern Benin. Between thirty and thirty-five women used each system to pump water from the ground or a stream. Each woman was responsible for farming her own one hundred twenty square meters of land. They also farmed other land collectively. The solar-powered irrigation systems produced an average of nearly two metric tons of vegetables per month. During the first year, the women kept a monthly average of almost nine kilograms of vegetables for home use. They sold the surplus produce at local markets. The earnings greatly increased their ability to buy food during the dry season which can last from six to nine months. People in the two villages with the …
