Abstract
Egypt appears to be particularly vulnerable to climate change especially with water scarcity problem. Climate change not only affects the temporal and spatial distribution of water resources, but also will increase the crop water consumption ( ). The aim of this study is to estimate the effects of climate change on irrigation requirement ( ) for ''Wheat" at different geographic regions in Egypt: El-Dakahlia, El-Fayoum and Assuit governorates were selected as Lower, Middle and Upper Egypt regions. The climate change data has been obtained from ''MIROC-ESM'' climate model with ''RCP 8.5'' climate scenario during 2018, 2040 and 2080 as a current, short and long term periods respectively. The results showed that the ETc would increase by 5 %, 8 % and 13 % in 2040 but, in 2080 would decrease by 8.5 % in Assuit. Whereas, in El-Dakahlia and El-Fayoum would increase by 8 % and 13 % respectively. The IR values would increase by 12 %, 21 % and 14 % to become ( 636.61 mm/season),(572.3mm/season) and (331.25 mm/season) in 2040 for Assuit, El-Fayoum and El-Dakahlia, respectively. But, expected to decrease in Assuit by 15 % to reach (478.4 mm/season) and increase by 23 % and 17 % to be (584.01 mm/season) and (339.85 mm/season) in 2080 for El-Fayoum and El-Dakahlia, respectively. These results indicated that, climate change would increase the water consumption for wheat in all examined regions in Egypt, and the highest impact would be in Middle and Lower Egypt followed by Upper Egypt during 2040 and 2080.
