摘要:Traditionally, dealing with chronic and inherent irrigation water scarcity in the western UnitedStates has meant augmenting supplies through the creation of large storage and diversion projects. Increasing competition for water from urban populations, mounting costs, and risingenvironmental concerns are making water management policies built on physical solutions lessviable, and alternatives are being sought. The use of water price as a policy tool is one suchalternative receiving increased attention from western water managers. Indeed, the largestprovider of irrigation water in the western United States, the Bureau of Reclamation (USBR),recently required irrigation districts in California's Central Valley to adopt conservation pricing asa Best Management Practice (USBR, 1998).
