Center-pivot irrigation in Saudi Arabia captured by Landsat 7, 2000

Detailed Description

Landsat 7 captured this image of center-pivot irrigation (green circles) in the Saudi Arabian desert in 2000. Images taken of the same location over several decades show the explosive increase of irrigated land over time, as hidden reserves of water have been tapped beneath desert sands to grow grains, fruits, and vegetables.
