1 Introduction
Egypt is the second national communication and will be a typical example of a developing country that is very susceptible to global climate change. The final climate of
Egypt is dry, hot, with a gentle winter season with rain over the coastal areas, and
a hot and dry summer season that exposes it to numerous threats to its economic,
social and environmental property. Global climate change has a general trend towards
warming of the air temperature, with an increase of humidity in the hazy days, misty
days, the turbidity of the atmosphere, regularity of hot days and sand storms [1]. Also,
expected to feature to the growing threats to national security fueled by a growing
population of regarding 104 million, of that almost 56.7% unit of measurement a rural
population, and 43.3% unit of measurement urban population to keep with applied
analysis for 2017 [2]. The population is calculated to realize 120 million by 2020, and
then the growth rate anticipated to be unchanged. Regarding 97% of the population
in Egypt lives on the Nile River depression (11 km
2 ), and so the Delta which about of
29,000 km
2 , and represents regarding 4% of Egypt’s total area [3, 4]. Incredible population intensification associated with harboring an enlarged demand on the already
irregular resource base. Egypt’s security threats which can be extra tormented by
the impacts of global temperature change on animal and agriculture in general as
well as water security, food security and impoverishment gap, and energy security
also. The increasing of human population related to loss of agricultural land because
of urbanization processes and alteration water accessibility concomitant with global
climate change create quiet opposes to agriculture [5]. Additionally, the drought and
salinity are the foremost vital environmental factors that triggered the decreasing
growth and productivity of plants [6]. Consequently, increasing water productivity is
a fundamental strategy to extend food production underneath conditions of restricted
water system [7]. In Egypt, the forage crops play crucial dependability in farm animal
production. Wherever, the forage crops are used in different features (Green fodder,
hay, and silage) characterized by the high feed conversion ratio to achieve the highest
net profit. Consequently, the water use efficiency had the highest correlation with
each contemporary and dry forage yields [8]. In this chapter, many attempts that
discussed are summarized at Fig. 1. Which illustrate the interactions between and
among the energy, water, land, and climate systems take place within a social and
economic context.
2 Climate Change Impact
Having explored the term environment and its implications, this part presents
the importance of water resources values to externalities related to environmental
impacts.
