This research aims to study the production and water situation of some agricultural crops in Lower Egypt and Upper Egypt, and to guide it when reclamation and cultivation in new areas, whether in the north of the valley or the south of the valley, by estimating the loss, whether in the quantity and value of production or the quantities of water used to cultivate these crops between Upper Egypt and Lower Egypt regions. It became clear from the results obtained from the research that land reclamation and cultivation in northern Egypt, such as Delta, Sinai and the northern coast, is more feasible than reclamation and cultivation in the south, due to the hot climatic conditions in the south, the increase in evaporation and the high water requirements of crops, in addition to the low feddan productivity of most of these. Crops in the south compared to their needs in the north. The results also indicate that the productivity of the water resource was higher for all selected crops in Lower Egypt than Upper Egypt, except for the crops of winter onions, garlic, winter tomatoes and winter potatoes. When the decision was taken to plant a thousand feddans of each crop of the crops under consideration in Upper Egypt, a loss resulted in both the value of production and the quantity of production, and the total loss in the selected crops amounted to about 875.64 thousand pounds, while the loss in the amount of water used amounted to about 2.37 million.
