Description

 Water transfer through market mechanisms has gained increasing attention as a means to achieve higher efficiency in water resource management. However, dealing with the transfer of irrigation water, which is characteristically different from resources of other kinds in the sense that it forms a part of a region’s water cycle,presents a severe challenge. This paper presents two case studies illustrating how the special features of irrigation water constrain the free trade of irrigation water resources. One case involves the water transfer within an irrigation project on the South Island of New Zealand. The other is related to the redistribution of water between regions within the Drought Water Bank in California, USA. Both are cases in which simple market mechanisms have not been applied. Public authorities responsible for the management of regional water resources handle the entire process of individual cases of water transfer. In such cases, public authorities conduct investigations related to the technological possibilities presented by the transfer and then carry out subsequent reviews of the project’s impact on regional economies and ecosystems. Social receptiveness is the strongest constraining factor of the free trade of irrigation water, which invariably creates relations among surrounding actors, irrespective of the transfer size.
