Crop areas were farmed in two highly diverse manners. Areas relying on non-irrigated cultivation (''secano''), which made up 85% of the entire crop area, depended solely on rainfall as a source of water. They included the humid regions of the north and the northwest, as well as vast arid zones that had not been irrigated. The much more productive regions devoted to irrigated cultivation (''regadío'') accounted for 3 million hectares in 1986, and the government hoped that this area would eventually double, as it already had doubled since 1950. Particularly noteworthy was the development in Almería—one of the most arid and desolate provinces of Spain—of winter crops of various fruits and vegetables for export to Europe.
