دراسة اقتصادية لكفاءة استخدام الموارد المائية في جمهورية مصر العربية باستخدام التحليل التطويقي للبيانات (DEA)‎

الملخص EN

The agricultural sector is considered one of the most important sectors consuming water, as it consumes about 82.5% of the total actual consumption of water.

irrigation water is the strategic element in agriculture and the basis of agricultural expansion, so the research problem was represented in the limited water resources and the low level of efficiency of its use in irrigation.

so the research aimed to estimate the economic efficiency and productivity of using irrigation water for the most important agricultural crops in Egyptian agriculture.

in achieving its objectives, the research relied on the use of descriptive and quantitative analysis methods, where some indicators of the economic efficiency of the use of irrigation water were used, in addition to the use of data encirclement analysis (DEA) as one of the linear programming methods that are used to measure the productive efficiency of the use of irrigation water, using the available data from the published and unpublished and issued by scientific authorities.

the results of the research related to indicators of economic efficiency for the use of irrigation water showed that winter onions were one of the most efficient crops in the study in terms of using irrigation water, according to indicators of economic efficiency, while summer rice and maize were among the crops with low efficiency in the use of irrigation water due to the low net return of the water unit, which amounted to about 612 and 507 pounds for each of them, respectively.

as for the rice crop, it was one of the inefficient crops in the use of irrigation water, due to the high water requirements needed to produce a ton of it, which amounted to about 1479 m3, and the low net return of the water unit, which amounted to about 612 pounds.

while wheat was one of the crops with medium efficiency in using irrigation water, the net return of the water unit amounted to about 1601 pounds.

the study also showed that the governorates of lower Egypt which have the highest efficiency in using irrigation water for rice production were Dakahlia, Kafr el-Sheikh, Beheira, Gharbia, Menoufia, and Qalyubia, where the efficiency degrees for each of them reached about 1.00, 0.955, 0.917, 0.908, 0.846, 0.836, respectively.

also, the governorates of lower Egypt also that have the highest efficiency in using irrigation water in summer maize production were Dakahlia, Menoufia, Kafr el-Sheikh, Sharkia, Beheira and Gharbia governorates, which were estimated at about 1.00, 0.928, 0.924, 0.918, 0.891, and 0.888, respectively.

the governorates of lower Egypt with the highest efficiency in using irrigation water for sugar cane production were Kafr el-Sheikh, Dakahlia, and Qalyubia governorates, where the efficiency degrees for each of them reached about 1.00, 0.946, 0.823.

while the highest governorates in central Egypt were Minya governorate, where the degree of efficiency was about 0.830, and the highest governorates in upper Egypt were Qena, Aswan, where the efficiency for each of them reached about 0.930, 0.910, respectively.
