Abstract

The main objective of this study was to investigate the effect of possible non-structural Management schemes with no need of changing irrigation systems and optimal use of agricultural water at the farm level, including improving irrigation water efficiency, changing planting dates and deficit irrigation with preserving the composition and area under cultivation in the region, . Management interventions were designed based on present irrigation management (amount, number of irrigation, etc. ). The main goal was to improve the optimum use of water in the agricultural sector to prevent the continuation of excessive withdrawal of groundwater resources. The information was collected directly from 158 farms, which represents the distribution of the existing conditions of the whole region, and the scenarios for improving the efficiency of irrigation were based on improving available higher efficiency in the region The results showed that improvement of irrigation efficiency for dominant crops in two regions of Dorodzan and Korbal, leads to savings in water allocation by 131. 5 (11. 2%) and 33. 8 (10. 83%) million cubic meters, respectively. Management scenarios of change in planting date using AquaCrop model simulation showed that upto 31. 6 (2. 7%) and 9. 17 (2. 94%) million cubic meters of water in the two regions of Dorodzan and Korbal can be saved. At the same time, different levels of deficit irrigation can reduce water consumption by 85. 5 (7. 3%) and 26. 2 (8. 4%) million cubic meters respectively. . All in all the results of this study show that in many cases, significant amount of water can be saved with minimal operation costs and preserving the existing structural conditions, even without changing the pattern of cultivation.
