“But the water problems of our world need not be only a cause of tension; they can also be a catalyst for cooperation

….If we work together, a secure and sustainable water future can be ours.”

Kofi Annan, February 2002

Comparing 1948-1999 and 2000-2008 TRENDSThere is an increase in the percentage of cooperative events in 4 basins:

Jordan, Tigris-Euphrates/Shatt al Arab, Ganges-Brahmaputra-Meghna, Danube

BAR-scale for MENA Region switches mode from negative to positiveGlobally 65.9% of the water-related events were cooperative 29.4% were conflictive events.

Meeting the demand Without managing the supply

Sustainability means providing an adequate and reliable water supply of desired quality –now and for future generations – in a manner that integrates economicgrowth, environmental protection and social development.

Ongoing IHP Projects in the Arab Region

Initiating Future Water Collaboration in the Arab region based on Arab Water Security and IHP-VIII: Water Security.

• An Expert Group Meeting was successfully organized in Sharm El Sheikh, Egypt during 17-18 September 2014. • A proposed initial title of the initiative is “Sustainable Water Resources Management under Scarcity Conditions in the Arab

Region”. • Fourteen regional water experts attended the meeting representing 8 Arab countries, namely: Egypt, Sudan, Oman, Bahrain,

Tunisia, Morocco, Kuwait and Jordan in addition to representatives of regional organizations and institutions such as League of Arab States (LAS), Arab Water Council (AWC) and UNESCO Cairo Office (UCO).

Capacity Building for Water Strategies and Action Plans formulations

• Joint collaboration with Arab G-Wadi Secretariat-Oman, LAS, ISESCO, AWC, GIZ, ALECSO. • A regional workshop is planned during 16-18 Nov. 2014

Gender Mainstreaming in IWRM at Rural Areas

• Preparation of a comprehensive technical study in Morocco in joint collaboration with UNESCO Chair on Water, Women and Decision Power of Morocco

• Support the organization of a special session within the 3rd Arab Water Forum in joint collaboration with the Arab Water Council

Groundwater Governance in the Arab Region

• Organization of a regional Workshop on Effective Groundwater Governance in the Arab Region, Sharm El Shiekh, Egypt; 19-21 September 2014

• Thirteen regional water experts attended the workshop representing 11 Arab countries, namely: Egypt, Sudan, Oman, Bahrain, Tunisia, Morocco, Kuwait, KSA, Yemen, Algeria and Jordan in addition to representatives of UNESCO Cairo Office (UCO)
