Olive cultivation is one of the main agricultural activities in North Sinai, as it aligns with the region's soil characteristics and available water resources. However, the cost of lifting and distributing well water presents a significant challenge to the sustainability of production. This study aims to Comparative economic analysis for the costs of lifting and distributing well water in olive farms in the governorate based on different energy sources, including electricity, diesel, and solar energy, while considering the impact of government subsidies and bank financing on these costs. The study relies on field data collected from farm owners, in addition to secondary data from official sources, using cash flow statements to calculate fixed and variable costs for each energy source under both financed and non-financed scenarios. The results indicate that solar energy is the most efficient and cost-effective option in the long run, especially without reliance on financing, whereas diesel proves to be the most expensive, imposing a financial burden on farmers. Additionally, bank financing increases operational costs due to high interest rates. The study recommends encouraging investment in solar-powered irrigation systems through financial incentives, restructuring energy subsidies to support sustainable projects, enhancing access to affordable financing for farmers, improving irrigation efficiency through modern technologies, and conducting future research to keep up with advancements in water resource management. Implementing these recommendations will support the sustainability of olive cultivation in North Sinai, enhance operational efficiency, and improve the overall feasibility of agricultural investment in the region.
