| Abstract | ||
| The study aimed to determine the optimal crop pattern through multi-objective linear programming and to assess the environmental impact of applying the proposed crop pattern scenarios in New Valley Governorate. The research relied on an analytical model (multi-objective linear programming) to select the most appropriate crop pattern under minimum, maximum, and combined minimum–maximum constraints of cultivated area, based on the determinants of land, labor, and water. This was conducted with the purpose of minimizing water requirements while maximizing returns. The study employed the multi-objective linear programming approach within the available physical and economic constraints of New Valley Governorate during the research period. The results indicated that, under the first proposed scenario, water requirements achieved a substantial and noticeable reduction, which positively reflected on the environment within the framework of the sustainable use of the non-renewable groundwater resources in the governorate. The research recommended adopting the proposed and suggested crop pattern based on the study’s findings, given its positive impact on maximizing net returns and reducing the water requirements of agricultural crops in New Valley Governorate | ||
