Gaddafi of Lybia build a man made river, which was destroyed by NATO.
The Great Man-Made River (GMR, النهر الصناعي العظيم) is a network of pipes that supplies water to the Sahara in Libya, from the Nubian Sandstone Aquifer System fossil aquifer. It is the world's largest irrigation project.[1]
According to its website, it is the largest underground network of pipes (2,820 kilometres (1,750 mi))[2] and aqueducts in the world. It consists of more than 1,300 wells, most more than 500 m deep, and supplies 6,500,000 m3 of fresh water per day to the cities of Tripoli, Benghazi, Sirte and elsewhere. It is also the world's largest irrigation project.[3] The late Libyan Leader Muammar Gaddafi described it as the "Eighth Wonder of the World.".[4] But in 2011 it was damaged by NATO, due to which Libya is still facing water shortages.
