Impact of future climate change on land and water productivity for wheat crop (Wasit Governorate, Iraq) abstract
In AquaCrop model was used to calibrate and verify the performance of the winter wheat crop in south of Iraq Al-Suwaira Research Station using data recorded in period 1/1/2008 and 31/12/2017. The results showed an increase in both annual and monsoon rains at the mid and end century periods for both RCP4.5 and REP8.5 scenarios implementing model GFDL-ESM2M. The annual and monsoon rains decreased in the EC-Earth model for both the RCP4.5 and RCP8.5 scenarios, while increased slightly in the CNRM-CM5 model under RCP4.5 and dropped with RCP8.5. Highest yield was recorded at the base period (2.36 ton/hectare) during the simulation period. The water productivity increased compared to the base period 2040-2050, while it was equal for both base period and the period 2020-2030 and in the RCP8.5 scenario.
