Abstract :
In most arid and semi arid regions, as in most parts of Iran, insufficient supply of water has become one of themost important constraints to economic development. In these areas, the main issue in water management is tofulfill the ever-increasing demand for water. The supply of water is usually limited, while the quantity of waterdemanded has increased mainly due to population growth. It is believed that a rationalized water pricing systemwould play a crucial role in the optimal allocation of water resources. Planning for efficient use of water isimportant when there is a severe limit to its availability. The demand elasticity for every good, service, or inputdetermines how a change in price, ceteris paribus, affects users’ quantity demanded. This study investigates thestructure of irrigation water demand by estimating the derived demand for water on one particular crop, barley, in Iran. The analysis is based on deductive econometric method, and on total statistical and panel data. A demandfunction was estimated after performing the relevant statistical tests. The price elasticity of irrigation waterdemand and other elasticities were also computed. Data and information from 2001 to 2006 from 26 provinces inIran was collected from secondary sources
