摘要

Previous related studies confirmed that Egypt falls under the "water poverty" line or the "water scarcity limit" estimated at around 1000 m~3 annually per capita of the renewal water resources and need the local needs in agriculture, industry, energy and the other necessary needs for the process of socio-economic development. Accordingly, "an increasing "water gap" arose, so the water allotment per capita shrank from 2500 m~3 in 1950's down to 600 m~3 and continue to shrink to reach around 250 m~3 by 2050 under the constant water allocation for Egypt and the overpopulation and the increasing water needs, reusing the water and put the virtual water to use, [5]". The aim of research is to study the economic use for agricultural water resources in the Northwest Cost via reconsidering the cropping pattern combination of agricultural crops. Therefore, Methodology and data sources could be explained as that The research used the descriptive and quantitative economic analysis and some other statistical methods to identify the relationships that govern the main variables besides the quantitative measuring; the multi-purpose programing method was used to set alternatives to the typical cropping pattern with regard to maximizing the utilization of the available water resources for agriculture under the constraints and limitations of the available economic resources in the Northwest Coast. Finally, the research results estimating the net return of water unit for the first and second alternatives indicated a rise in the return of water unit in the proposed crop structure versus the current return of water unit in the crop structure, the second scenario was the best according to the return value of water unit in the proposed crop structure as the rise came to 20.9% than the current crop structure. It was indicated that the return rise achieved in this scenario came to 103 million LE with an increase of 15% than the net return in the current crop structure. Estimation results showed also that the highest average of water unit return was confined to Prickly Pear in the 3 alternatives followed by tomato and apricot, as for the third alternative, assessments indicated a rise in water requirements for the proposed pattern with 2268 million M~3 with 299.2% than that its current counterpart resulting in a reduction in such requirements for other crops i.e. wheat, onion, garlic, winter tomato, winter eggplant, groundnut, summer watermelon, summer cantaloupe, date palm and prickly pear.
