Current demand for water resources in Egyptian agriculture

Abstract

Water is one of the most important inputs and elements of development, and the importance of water in Egypt is increasing due to the lack of resources and increased demand in recent periods, where rain is scarce and covers most of its deserts. The River Nile is the main water supplier in the Arab Republic of Egypt, where the share of the river about 55.5 billion cubic meters per year, and the problem is limited to the study of the current and future use of water, while Egypt suffers from the constant amount of water available to cover these uses, The high rates of Egyptian population growth, with Egypt's share of water remaining constant, and hence the problem of water shortage, is a threat to the national economy in general and the agricultural sector in particular. The aim of the study is to use water for the time being and to work to increase the efficiency of water use in future years The study shows that the quantities of water used in irrigation for agricultural crops in Aswan fluctuated between the minimum and the decrease, ranging between a minimum of about 40.1 billion m3 in 2012 and a maximum of about 62.1 billion M3 in 2008 with an annual average of about 50.48 billion m3 during the same period. And the study of the equation of the general time trend for the quantities of water used for irrigating agricultural crops in Aswan and it shows that there is no mathematical picture suitable for the nature of the data and that the data revolve around the mean arithmetic. The problem of the study is limited to the multiplicity of current and future agricultural uses of water while Egypt suffers from the constant quantity of water available to cover these uses, especially in light of the high rates of Egyptian population growth with the stability of Egypt's share of water. And the agricultural sector in particular. Despite the continuous efforts to increase the Egyptian agricultural production, the value of the gap is increasing in some basic crops in a way that the national economy is exposed to the sharp effects of global variables, C Egyptian. Which necessitates the need for horizontal expansion. However, this expansion is governed by many factors. The most important of these is the scarcity of water resulting from Egypt's limited share of Nile water at the present time, with the per capita decline reaching 540 m3 in 2016, which is below the poverty line. The problem of the study is limited water resources and the diversity and increase of agricultural activities, especially food. Therefore, the identification of optimal economic use becomes a fundamental problem to be allocated to the distribution of these limited water resources to the growing and growing needs according to different scenarios commensurate with local and global situations.
