The 7th meeting of the Water Expert Group of the Union for the Mediterranean (UfM) took place in Barcelona in July 2017. The purpose of the meeting was to discuss the drafts of the Working Programme prepared by the UfM secretariat in collaboration with the GWP-Med. In addition, there was a session dedicated to presenting different initiatives related to the water-energy-food-ecosystems nexus The UfM gathers 43 countries, from the European Union, North Africa and the Middle East of the Mediterranean area. The creation of the Water Expert Group (WEG) was mandated by the Euro-Mediterranean Ministerial Conference on Water (22 December 2008, Dead Sea, Jordan) and confirmed by the UfM Ministerial Declaration on Water (Malta, 2017). The Ministers agreed to entrust the Group of Water Experts (WEG) to develop and execute an UfM water agenda. The WEG is comprised of high-level representatives from the relevant Ministries and convenes twice a year.
