Coastal lands are one of the complex ecosystems between the land and sea, characterized by high ecological diversity and also by extremely specialized and important species. Coastal areas, because of their position between land and sea, are attractive for many human activities. Unfortunately, coastal lands have had a long history of misuse, exploitation, and mismanagement. Sustainable development of Egypt's desert is the only alternative to overcome the major problems of the country particularly: overpopulation and the shortage of food, fodder, oil and raw materials for strategic industries. Unfortunately, cultivation of the conventional crops e.g. wheat ... etc. in the desert is causing a quick depletion of its groundwater. The natural wealth of the flora of Egypt's desert can be considered the backbone of its sustainable developmental programs. Vegetation forms of the coastal and inland deserts, including those of the Afro-Asian and Red Sea coastal lands, are shrinking at an accelerating rate, particularly in relatively highly populated areas.
