In lakes and rivers, the management of water supply and quality has largely proceeded on the basis of local considerations rather than at the global scale that has been more typical of environmental management of the atmosphere and ocean. It is increasingly apparent, however, that high-quality water resources are now in critically short supply not only because of local problems such as over-irrigation and eutrophication, but also as a result of larger-scale climate effects on the hydrosphere. This magnitude of impact will increasingly require the integrated monitoring and management of water resources on a planetary scale, with world criteria for environmental assessment, restoration, and conservation strategies. The increasing extent of world trade in potable freshwater heightens the urgency for establishing international approaches, criteria, and regulations.
