"Farmers in South Asia and sub-Saharan Africa are increasingly taking up small-scale irrigation schemes as drought threatens the security of food supplies, a report by the International Water Management Institute (IWMI) said," Reuters reports. "Small-scale irrigation technology, such as motorized pumps and hosing to access groundwater, could cost a sub-Saharan African smallholder $250 or more but could improve crop yields by between 75 and 275 percent, the report said," Reuters adds. "If there is more investment in small-scale irrigation, it means food supply in those countries is more secure. It won't replace the need for staple cereal crops, but it gives farmers more insurance against a food crisis," said Colin Chartres, IWMI director general, according to the news service. "We are going to have to come up with ways of making water go much further if we are going to grow 70 percent more food by 2050 on about 10 percent less water than we use today," he added, Reuters notes (Chestney, 8/24).
