Abstract
In Egypt, being an arid country with low erratic rainfall of up to 700mm
per annum, water management is of particular importance. Without an
efficient management, water will become a constraining factor in the socio-economic development in Egypt. Water resources provide multiple services that are essential to human development, such as water for food
production, drinking-water, conservation of natural ecosystems,
recreation and hydropower. The growing population of Egypt and related
industrial and agricultural activities have increased the demand for water
to a level that reaches the limits of the available supply.
The main objective of the current study is scrutinizing how to maximize
the economic outcomes from irrigation water and enhance the environmental and social performance of irrigation water.
The maximization of the economic value of irrigation water will carried
out using the linear programming approach. The applied methodology in
the current study comprises several steps that can be summarized as
follows: determining the study area, collecting required data and
information about different water uses, developing scenarios considering
the various national constraints to optimize the water allocation in a way
to maxirnize the economic water returns, and determining the optimal
cropping pattern Finally, the study proposed a cropping pattern which increased the economic value of irrigation water from 0.88 LE/m3 to 0.92 LE/m3 and increased the production of some strategic crops like Wheat, Maize, by 5% and 10% respectively and increased the production of Seasame to 8 thousand tons, Soybeans to 25 thousand tons, and sunflower to 3
thousand tons respectively besides, decreasing the cultivated area of high
consumptive water crops like Rice by 10%.
