Just before this document was finalized, the global warming issue once again made the cover of Time (April 28, 2008). This is perhaps a good measure of how central and influential the global warming topic would be on people.
Inside the magazine, a twelve-page special report details why becoming green is crucial for the world. It covers many different issues, from signing aggressive carbon regulation to working on alternative energy. In a way, they are all directly or indirectly related to the main idea of this document, which basically examines the water sector from the point of view of the effect of climate change on droughts and water scarcity and its implications for policy and sustainability.
The document draws information from many recently published peer review reports and papers. Hopefully, it will serve as an important reference for discussions on the influence of climate change on droughts and water scarcity in dry regions during the Water Tribune week in July 2008.
The author wishes to take this opportunity to thank the World Bank for providing the needed support to produce the document, particularly Martha Perdomo for methodically reviewing the document. Thanks also to other colleagues who kindly provided many important and helpful suggestions.
