Global domestic water use for year 2000 (millions of m3/year per 0.5 degree grid cell).

Map description and dataset provided by: Water Systems Analysis Group, Complex System Research Center, Institute for the Study of Earth, Oceans and Space, University of New Hampshire, USA

DescriptionDomestic Water Use

This map shows the distribution of contemporary domestic water use throughout the globe and illustrates the considerable demand for water in the highly populated and industrialized regions of the globe. “Hot Spots” of very high domestic water demand can be readily seen in developed nations associated with the metropolitan areas.

Interpretation

Domestic water demand is linked closely to both population growth and economic development. Over the past few centuries global water use including domestic use has grown nearly exponentially with the more populous and faster growing areas showing the greatest increases in use. With increases in population and industrialization of developing nations the world may face substantial challenges to water infrastructure and associated water services potentially incurring large economic costs.
