AB: We investigated the feedback between changes in potential evaporation and future irrigated acreage in Southeastern Turkey using observed and simulated meteorological variables. Under the framework provided by the Complementary Relationship, the results of our research demonstrate the existence and quantify the magnitude of scale-dependence in the relationship between irrigated area and the amount of water required per unit area. Assuming that the changes in future evaporation conditions will be similar to the observed changes, water use for irrigation is expected to decrease over 50 percent in selected irrigation sites. This study lends credibility to the hypothesis, which suggests that future land use modifications in the form of irrigated agriculture in Southeastern Turkey have the potential to strongly affect potential evaporation - a key parameter influencing the amount of water required for irrigation. Incorporating this decrease in overall planning of future irrigation projects could lead to significant water savings and improve sustainability of water resources in the region.
