Human being’s continuation depends mainly on water which covers three-fourths of the earth’s surface. However, seawater, salt water, represents about 97% of the earth’s water and the rest is fresh water. The deficiency of potable water resources in most of MENA countries threatens their stability as a result of population growth, and their dependency on little amount of groundwater and rain water in different aspects of life. Using solar power, especially concentrating solar power, in seawater desalination will participate in solving water-shortage problems, and it will play significant role in keeping the environment safe and clean as a fact of using renewable clean energy instead of fossil fuel which can cause harm for the environment. This paper illustrates how the water desalination, based on solar power, is sustainable and show the real potentials of MENA region in order to limit its water deficits in a long-term perspective, and represents the adequate combinations of technologies for concentrating solar power (CSP) and seawater desalination in order to help providing the demand of fresh water to the North Africa and Middle East by exploiting the potential of inexhaustible renewable water resources and the existing of solar power which can be used for seawater desalination. Environmental issues related to the process of seawater desalination have been taken in consideration as an important part of the paper.
