دراسة اقتصادية لكفاءة استخدام مياه الري في جمهورية مصر العربية

الملخص EN

The research aimed to study the efficiency of irrigation water use in the Republic of Egypt, by studying the quantities of irrigation water used at the level of the regions of the Republic, as well as at the level of the governorates in those regions, and studying and identifying the provinces with the highest consumption of irrigation water, as well as studying the efficiency of the delivery of irrigation water at the level of those regions and studying the technical and economic indicators for the efficiency of irrigation water use, the study resulted in a set of results, the most important of which is that the highest net yield per unit of water for summer lug crops was for cotton, followed by sugar cane.

the crop of maize is the crop of sorghum, then the crop of rice.

while by studying the net water yield per unit of winter locust crops, the permanent alfalfa crop came to the fore with the highest net water yield per unit at the level of the three regions of the Republic, while the wheat crop came in second place.

the level of the regions of the Republic is few, which makes them the most flexible crops when drawing the varietal map of crops at the level of the Republic.

and by studying the productive efficiency of the study crops (rice, maize, sugar cane, wheat, sugar beet, sustainable alfalfa) at the level of the governorate, by using the data envelope methodology for winter crops, Menoufia was the highest governorate in lower Egypt for the production of wheat crop, and for the sugar beet crop, the Gharbia came in the first place, and for the sustainable alfalfa crop, Kafr El-Sheikh governorate came in the first place.

for summer crops using the data envelope methodology, Kafr El-Sheikh governorate ranked first in the production efficiency of the rice crop while Dakahlia governorate has the highest efficiency in the production of maize crop.

Kafr El-Sheikh governorate ranked first in the production efficiency of sugar cane crop.

this may be attributed to the decrease in the water ration in lower Egypt, and this is what is justified by the effect of the relative decrease in the productivity.
