Fossil water aquifer system in northeastern Africa
The transport of pipe segments for the Great Man-Made River in the Sahara desert, Libya, during the 1980s: a network of pipes that supplies water from the Nubian Sandstone Aquifer System, a fossil aquifer in the Sahara desert of Libya. The Great Man-Made River is the world's largest irrigation project.
The Nubian Sandstone Aquifer System (NSAS) is the world's largest known fossil water aquifer system. It is located underground in the Eastern end of the Sahara desert and spans the political boundaries of four countries in north-eastern Africa.[1] NSAS covers a land area spanning just over two million km2, including north-western Sudan, north-eastern Chad, south-eastern Libya, and most of Egypt. Containing an estimated 150,000 km3 of groundwater,[2] the significance of the NSAS as a potential water resource for future development programs in these countries is large. The Great Man-Made River (GMMR) project in Libya makes use of the system, extracting substantial amounts of water from this aquifer, removing an estimated 2.4 km3 of fresh water for consumption and agriculture per year.
