Abstract

Climate change is a challenging topic for irrigation researchers as it has affected crop water demand. In the present study, the effects of Climate change on minimum temperature, maximum temperature, precipitation, and the water demand of 12 crops including wheat, alfalfa, potato, barley, garlic, cucumber, watermelon, pumpkin, sugar beet, rapeseed, grain maize, and bean were investigated and also a trend analysis was carried out up to the year 2050. The impacts of implementing and not implementing the irrigation efficiency enhancement, the cropping pattern changes and the development of the early-maturing cultivars as the adaptation strategies in combination with Climate change scenarios were investigated between the water years 1399– 1428 (2020– 2050). The results showed that without implementing the adaptation strategies, the net irrigation water requirement would increase by 3. 98% to 8. 38% compared with the recorded data. Growth in the irrigation efficiency up to the potential efficiency would cause a 19. 23% reduction in the Gross irrigation requirement on the average. By implementing the cropping pattern changes strategy through stopping the cultivation of some water-intensive crops such as alfalfa and developing the cultivation of rapeseed, net irrigation water requirement would decrease by 10. 9%. By replacing late-maturing potatoes by the early and medium-maturing cultivars and developing of early-maturing grain maze cultivation, Net irrigation requirement decreased by 8. 86%. Furthermore, the results revealed that implementing all the above-mentioned adaption strategies would reduce the Gross irrigation requirement by 34. 0%. Hence, the three above-mentioned strategies can be used as the measures that executive managers and farmers choose to implement in order to adapt to Climate change.
