In the framework of the MEDCOP Climat held in Tangier (Morocco) on 18 and 19 July 2016, the thematic water session “Challenges of Water/Energy/Food Security Alliance to face Climate Change” was organised on Monday 18 July afternoon to come up with the best Mediterranean solution in the water sector as a Mediterranean recommendation for the COP22. The Mediterranean Water Knowledge Platform together with the “Water-energy-food security nexus mainstreaming into policies and institutions in the MENA Region” were presented and discussed. A general agreement was reached among the 70 participants to integrate the 2 solutions into a unique one. Indeed, they both tackle the governance challenges with an interdisciplinary approach, the Nexus requires data that can be provided by the Knowledge Platform and the WEF nexus can be part of the white papers to be developed as a product of the platform to support decision making for water planning. Finally, it was felt that the nexus should be renamed as Alliance to be more positive and extended to other sector, covering at least the environment and potentially health.
