The changing status of water as a natural resource.

This paper considers the way freshwater resources are perceived in an era of climate change. It is suggested that in many parts of the world water is moving from being a renewable resource (or continuous natural resource) to a potentially renewable resource (PRR). In some areas water is moving from being a PRR to a nonrenewable resource. Selected water problems from three continents are investigated in the context of this theoretical construct. Recent experience in the United Kingdom is then also investigated as a case study of these changes before brief conclusions are drawn. [ABSTRACT FROM AUTHOR]
