Agricultural water availability, water salinity, irrigation sources and irrigation systems in pistachio farms in Iran were studied. One hundred respondents were selected through a multi-stage random sampling in Kerman Province (Iran) during 2003-04. The results revealed that 70% of farmers experienced agricultural water limitation, and 82% utilized low-quality water with a salinity degree of more than above 5 millimohs. In 94% of the sampled farms, water was extracted from deep wells, and 97% of the farms were managed under a traditional irrigation system popularly called flood irrigation. These bottlenecks resulted in high water extraction costs, low water use efficiency, and low pistachio productivity per unit of water utilized. Consequently, the profitability of pistachio orchards has declined recently, mainly owing to water limitation. To achieve a certain level of profitability that ensures a minimum net benefits, at least in the short run, farmers have to increase the extraction of underground water.
