Abstract
In this chapter, ETo values were calculated for three studied governorates using Penman-Monteith equation, and then water requirements for the studied crops were calculated. Furthermore, the effect of climate change on ETo values were calculated after comparing between RCPs scenarios developed from four AR5 global models and its four RCPs scenarios with measured weather data for a 30-year period, where goodness of fit test was applied. The analysis indicated that RCP6.0 scenario from CCSM4 model has the highest agreement between measured and projected weather data. Thus, the data from this scenario was used to develop more accurate values for water requirements for the three crops grown in the three main regions in Egypt in 2029/30 season.
