The study problem was represented in the decrease of the Egyptian irrigation water resources which requires facing the problem of severe water scarcity. The research aims to study the rationalization of irrigation water use through two important methods: firstly, putting the return of the water unit into consideration when setting the appropriate crop composition and the second method is putting into consideration the foreign trade policy of virtual water. There are crops with a high return per unit of water, the most important of which are vegetable crops, the responsible authorities must work to expand their production, especially as they are important export crops. And crops with a low or medium return per unit of water which are import crops, and are linked to the level of food security. Therefore, its area cannot be minimized, and it should be expanded vertically only, if more food security is required. There are crops such as some vegetables and legumes, and these should not be expanded. As for the virtual water trade, it became clear that the cereal crops, namely wheat and corn, are import crops, and from these two crops large quantities of virtual water are achieved amounting to about 14.3 billion cubic meters. As for export crops, most of them are crops with low water needs per ton produced, with the exception of cotton and rice crops, the per ton of water requirement is high, and therefore not expanding their cultivation represents an effective policy to rationalize the use of irrigation water.
