Tapping into fossil ground water, Saudi Arabia has been steadily developing agricultural fields using center pivot irrigation. A remarkable example is in the Wadi As-Sirhan Basin in northwest Saudi Arabia. In the 1984 Landsat image (top), no fields are yet present. By 2000, ASTER showed extensive farming activity (middle); vegetation is bright red. And by 2011, the ASTER image shows several areas where wall-to-wall fields were developed, each about 1 km in diameter (bottom). The images cover an area of 19.5 x 33 km, and are located at 30.5 degrees north latitude, 38 degrees east longitude.
