| Abstract | ||||
| The optimal utilization of agricultural productive resources is considered one of the most important goals of agricultural economic development in the Egyptian agricultural economic structure. between production and consumption, Therefore, the research aimed to study the current situation of the current crop structure, and to reach the most appropriate crop structure, which reduces water needs and maximizes the total net yield of agricultural crops at the same time using the method of programming goals. In addition to working out different scenarios and alternatives for cropping structure to help the decision-maker and decision-maker achieve sustainable agricultural development in South Sinai; It was found from the results that the first scenario achieved a net return that exceeds that of the current cropping structure, and that it achieved a surplus in water needs to compensate for the lack of water resources in the governorate. The second scenario (achieving food security): the expansion of the agricultural lands cultivated with wheat, barley, and beans to reduce the food gap, and maximize the net yield. It also achieved a saving in the amount of water needs compared to its counterpart in the current crop structure, and an increase in the net water unit yield greater than its counterpart in the crop structure. The current crop is to achieve a surplus in daily labor, and the study recommended the need to educate farmers about the application of the proposed crop combinations that achieve the highest possible return for them with low water needs.
