The demand for water has been increasing steadily with increases in population and standard of living. The food and energy crises of the Seventies have made water resources development a priority issue in many countries. Agriculture currently accounts for 80% of all global water consumption but hydroelectric generation does not consume any water. Since irrigation and hydropower generation are compatible uses of water, most recent water developments include both these issues.
Quantity of water available to any country is limited, but demands are continually rising. Accordingly, water use has to be made more efficient and options like interregional water transfers have to be explored. The paper outlines the problems and prospects associated with long distance water transfer projects and discusses the latest plans for this type of development in the People’s Republic of China.
