Egypt is predominantly desert and only 5% of Egypt‘s total land is cultivated and permanently settled. It is well-known that soil and water are fundamental resources for agriculture. However, water is the most limiting factor for crops’ productivity. Unfortunately, water resources in Egypt are becoming scarce. Surface-water resources originating from the Nile are now fully exploited, while groundwater resources are limited.
The objectives of this study are mainly concerned with a descriptive and quantitative analysis of the available land and groundwater resources in Egypt. Besides, determining suggested cropping patterns in desert lands on the light of groundwater limitation.
To fulfill the study main goals, a non–linear programming model was applied to achieve this purpose considering groundwater constraints. The objective function is concerned with maximizing the net revenue of the irrigation groundwater per unit. This study depends of secondary data collected from different sources.
The results of this study show that, among the cropping patterns obtained by the five models, the third model is the best cropping pattern because it maximizes the net profit, followed by the fourth model. These two models save approximately 45.8% and 35.5% of the available groundwater resources for a hundred of years respectively. Although the first and the second models save approximately 61.4% and 54.2% of groundwater consumption respectively, these two models reduce the net revenue, estimated at approximately 26.9% and 36.0% out of the highest net revenue respectively.
