Water Availability in Africa: 1979 to 2010

Caption

Researchers analyzed water availability trends in African maize-growing regions from 1979 to 2010. Each quarter-degree grid cell represents a 200-square-mile area and is colored according to its average water availability level during the maize growing season. In redder areas, water availability is more limited by rainfall levels, while bluer areas are more limited by evaporative demand.
