Sommario/riassunto

The Middle East and North Africa (MENA) Region is one of the most water stressed regions in the world. Water scarcity has already become a challenge to development in many of the countries. Due to increasing population and Projected climate change impacts, MENA's annual water demand gap is projected to grow five-fold by 2050, from today's 42 Km3 to 200 km3 by 2050.Despite its extreme scarcity, water is managed poorly. Inefficiencies are common in the agriculture, municipal and industrial systems; and many utilities are financially unsustainable. As a result, countries overexploit their fossil
