This is one of Libya's largest agricultural projects. Because only about two percent of Libya's land receives enough rainfall to be cultivated, this project uses the underground aquifer. The green circles in the desert frequently indicate tracts of agriculture supported by center-pivot irrigation. The agricultural project is an easy-to-recognize landmark for orbiting astronauts aboard the International Space Station. The Libyan government also has a project called the Great Manmade River to pump and transport these groundwater reserves to the coast to support Libya's growing population and industrial development. As of December 2011, the excessive exploitation of the aquifer has provoked the complete drying up of the lake in the oasis.
