Abstract
rid and semi-arid regions of the world is mainly characterized by lack or little amount of precipitation as well as irregular tempo-spatial distribution of annual rainfall and highly evapotranspiration. On the other hand, recent permanent drought in East Azerbaijan province has led to a reduction in available water resources, a sharp drop in the groundwater levels, Urmia Lake receding and drying and increasing saline lands surrounding the Urmia Lake. Also the orchards and farm lands that seriously depend on groundwater level have been indiscriminately and disproportionately developed related to the climate condition. Therefore, modification of agricultural patterns is the best way to efficient water use in agriculture and is considered as the only practical solution in relation to the sustainable development of agriculture. This study was conducted in order to determine the appropriate area for growing pistachio orchards and replacing it with second and third order of gardens.
