The Middle East and North Africa (MENA) is the most water-scarce region in the world. A deserted environment of the region caused absolute water scarcity in such countries as Yemen, Jordan, Libya, and others. What makes the water situation in the MENA especially complex is the combination of acid climate with the political instability of the region. Effects of climate change, droughts and floods exacerbate in conditions of violent conflicts, poor water management, and population growth. The complex political situation slows down water management of the most important rivers in the region - the Nile, the Jordan, and the Tigris-Euphrates – which are all transboundary. Moreover, conflicts in Iraq, Libya, Syria, and Yemen lead to high number of internally displaced people, deprived of access to water and sanitation.
