Mapping the world by watershed

From World Resources Institute’s Watersheds of the World (2003) visualizations of some social-ecological properties of the world’s major watershed:

Cropland Area by Basin

Average Population/km2 (1995)

Water availability per person (1995)

The map shows the 114 major watersheds in the world. The map includes the largest transboundary watersheds and small basins that are representative of a particular geographic area. Omitted regions, shown in white, are primarily smaller coastal drainage basins or regions with no permanent rivers (more info).
