Percentage of Other Lands covering Source Watersheds

The use of the land covering the watersheds have an enormous impact in the cost and treatment of the water, as well as for the availability and quality of the water supply. Globally, a watershed is covered by 40 percent of forestall area, 30 percent of cropland and 20 percent of grassland and pasture; but it will vary from country to country. This footprint analysis involve 534 cities, who draw water from 20 percent of the world’s land surface.
