The research aimed to study alternative economics of rice through the relative scarcity of water in Kafr El-Sheikh Governorate, and to develop a concept to reduce the cultivated areas in the governorates in line with the requirements of producers and the goals of the national economy, Study the development of the productive capacity of the rice crop and alternative crops in Egypt and Kafr El-Sheikh Governorate,So Study the relative importance of the cultivated area of the rice crop in the governorates and estimate the separate impact of the area and productivity on the production capacity, The rates of temporal change indicate that there is a decrease in the production capacity of the rice crop with its two elements, the cultivated area and the acre productivity at the national and local levels in Kafr El Sheikh Governorate, and Kafr El Sheikh Governorate contributed about 20.8% of the rice production capacity in the Republic, nd the effect of feddan productivity on production capacity exceeds the effect of the cultivated area in the governorates of Dakahlia, Beheira, and Gharbia, and that the effect of the cultivated area on production outweighs the impact of feddan productivity. In the governorates of Kafr El Sheikh, Sharkia, Damietta.
