High flying satellites, which have already proved their mettle in delivering television programs, cell phone calls and views of our neighborhoods (thank you, Google Earth), can also locate potable water in countries such as Niger where droughts have made it scarce, the European Space Agency (ESA) announced this week.
The agency said satellites had successfully pinpointed 90 locations in western Niger where, based on satellite images taken between 1993 and 2007, drinkable surface water was likely to be; the Regional Center of the Permanent Interstate Committee for Drought Control (AGRHYMET) confirmed the satellites were right in all cases. AGRHYMET is a Niger-based agency formed in 1974 to gather information about food availability and the management of water and other natural resources in the Sahel, the region in Western Africa that forms the border between the Sahara desert to the north and the less arid forests to the south.
