Abstract :

In addressing water crisis, most countries are focusing on the management of water demand instead of water supply. In dry and semi-dry areas of Iran such as Fars province, water is an important factor in economic development and major input in agricultural production. The purpose of this study is to assess impacts of different policies for decreasing of applied water for irrigation and increasing water price on cropping patterns .Data were gathered from a stratified random sample by personal interviews of Aspas and Bakan's farmers in Eghlid region which used both surface and ground water. PMP model and CES production function was applied for both areas. The findings showed that the scenarios of 10% decrease in applied water and doubling of irrigation water price did not significantly change optimal cropping pattern compared with the base year cropping.
