CROPWAT 모델을 이용한 기후 변화에 따른 이라크의 밭작물 관개용수량 및 관개계획 모델링

The objective of this study is to determine the impacts of potential climate change on daily and total crop water requirement (CWR) of citrus trees in Iraq (Three provinces; Baghdad, Sallah Aldeen, Wasit) using crop modeling (CROPWAT 8.0) in conjunction with the climate scenarios derived GCMs. Baseline climate is based on the 30 years period from 1989 to 2019 of the mean daily normal, and two time periods in the future years (2020 to 2050). The climate parameters of the temperature, precipitation, relative humidity, sunshine duration and wind speed were downscaled using the GCMs methods. To determine the future crop water requirements (CWR), the CROPWAT model (FAO, 1992) was used to simulate the daily and the season total CWR and irrigation requirements for the present and the future decades. Crop evapotranspiration (ET) and Reference crop evapotranspiration (ET) for crop were determined using CROPWAT 8.0. The enable efficient use of water and better irrigation practices irrigation scheduling as the supply of water through rainfall is limited in these areas. The study will show that effective water requirement and irrigation scheduling for the crop (citrus tree) in Iraq. the first results show for historical 30 years to Baghdad station the total Etc (1442.3mm/dec) and the total effective rainfall (143.5mm/dec) and the total water irrigation requirement is (1298.8mm/dec) for 12 months to citrus trees. Hence irrigation requirement is needed to satisfy crop water requirement. That lead us the effective water is enough to compensate crop water requirement and the how much we need water for irrigation during the season or during the growth and optimum yield and extension and increase the orchard (citrus trees) without any economic loss. The main problem irrigation in Iraq includes declining of water quality, shortage of water resources after new dams along two rivers in Turkey and Syria are developed, climate changes and low water productivity in the unit area. This study will give us the great knowledge in water requirement and irrigation scheduling to get a high production and horizontal expansion. The CROPWAT model allows the development of irrigation schedule for different management conditions and the calculation of scheme water supply for different areas under different crops.
