Situation of Water Use Efficiency in Egyptian Agriculture during the Period 2012-2016

THE CURRENT research aims to enrich efforts exerted to increase crop production efficiency, which requires improving water use efficiency without posing negative impacts on the quantity or quality of water at the level of inlets. The most important results of the study were that the amount of losses in irrigation water reached its highest value between the field and the dam by about 7.815 billion m^3, while the amount of water lost between the dam and heads of irrigation canals reached about 5.525 billion m^3, but between the heads of the canals and the field it reached about 2.288 billion m^3. The productivity efficiency of the irrigation water unit, the net return of the irrigation water unit, the return of the invested pound, and the ratio of irrigation costs to total costs reached its maximum value in winter crops compared to summer crops at the level of the Republic. Finally, the research recommended that the government perform periodic maintenance of irrigation water canals along various stages, especially in Upper Egypt.
