This report is the first regional assessment to comprehensively assess the impact of climate change on water resources in the Arab region as a single geospatial unit by generating ensembles of regional climate and hydrological modelling projections until the year 2100. It is also the first to conduct an integrated assessment of these climate change impacts as they effect the socioeconomic and environmental vulnerability of Arab States.
The findings presented in this report are based on a common and uniform methodological framework applied across the Arab region, which thus allows for regional dialogue and exchange among Arab stakeholder groups. Both the preparation and the findings of this report have informed policy dialogue on climate change at the Arab regional level. It has enhanced the capacity of governments, experts and civil society to draw upon climate science to inform decision-making by regularly informing, and engaging with, them throughout the preparatory process via intergovernmental sessions, expert groups, consultative forums, workshops, working groups, task forces and high-level events.
