The Middle East is a region of international concern and political unrest. This book forms a complete reference to both the hydrological as well as the social, economic, political and legal issues in the region and shows how water shortages threaten the renewal of military conflicts and disruption in the area. With resources over-extended due to natural and human causes, the book analyses the river basins of the Euphrates, Tigris, Nile and Jordan and provides detailed study of the hydrology, hydrography and geography of these river basins; it also analyses the needs of the economies and societies of the countries bordering these basins. Conclusions on likely areas of conflict are set within the legal framework of the Helsinki and International Law Commission Rules.
