VALUE OF WATER IN IRRIGATED CROP PRODUCTION USING DERIVED DEMAND FUNCTIONS: A CASE STUDY OF SOUTH SASKATCHEWAN RIVER IRRIGATION DISTRICT1
Authors:Suren N Kulshreshtha  Devi D Tewari
Abstract:ABSTRACT: Water abundance has led most North American societies to use water freely without priorizing its use. As water scarcity becomes reality in the southern part of Saskatchewan, planners and managers of water require information about the value of water in irrigation, as well as in alternative uses. In this study, the value of water to the producer in irrigation is developed both for the short and long run. The basis of this imputation is a derived demand function for water using linear programming. Water demand was bound to be inelastic at lower prices, and highly elastic at higher prices. The short-run value of water varied between $0.44 and $127.82 (1986 dollars) per acre-foot for different levels of product prices. However, the long-run value was estimated between zero and $1.59 per acre-foot of water.
Keywords:value of water  irrigation water demand  Saskatchewan
