Caption: False-colour Landsat satellite image of circular, pivotally-irrigated wheat fields east of Riyadh, Saudi Arabia. Young growing corn appears in red, with older, more mature crops appearing almost black. Water is tapped from deep fossil reserves (underground wells) and fed through large rotating booms to water crops that would otherwise die in this barren region. In an effort to approach self-sufficiency in food production the Saudi's instigated an expansion program of irrigated agriculture in the early 1980's. They used this method (called center-pivot) primarily but also introduced some canal irrigation.
