Global freshwater resources: quantity and distribution by region
Philippe Rekacewicz, UNEP/GRID-Arendal
Glaciers and icecaps contain approximately 70% of the world's freshwater, but groundwater is by far the most abundant and readily available source of freshwater. This graphic illustrates the quantity (in cubic kilometres) and distribution of the world's freshwater resources in glaciers and permanent ice caps, in groundwater, and in wetlands, large lakes, reservoirs and rivers. Further information is given in the accompanying text.
