The aim of this investigation is to evaluate some proposed adaptation measures in order to overcome the projected impacts of climate change over on-farm irrigation system in Egypt. Improve irrigation systems efficiencies, change irrigation systems, and deficient irrigation were evaluated by using multi-criteria approach of evaluation. Adaptation measures were studied under current climate conditions and climate change projections of IPCC SRES scenarios for years 2025s, 2050s and 2100s, and evaluated regarding to the change in crop-water demands, change in crop-yield, change in water use efficiency, irrigation-energy requirements and the abetment cost. Improving surface irrigation efficiency was likely had a higher potentiality to overcome the negative impacts of climate change in old land. Deficit irrigation had negative effects on overcoming the impacts of climate change, but it could be acceptable for the conditions that the water saving is more important than crops reduction.
