Global Issues in Water, Sanitation, and Health: Workshop Summary
National Academies Press, Sep 25, 2009 - Medical - 328 pages
As the human population grows--tripling in the past century while, simultaneously, quadrupling its demand for water--Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet.
