The Mission Lighthouses come as a response to a number of obstacles and challenges in major European sea and river basins. To tackle these challenges, four basins have been selected and identified at the Atlantic-Arctic, Mediterranean Sea, Baltic-North Sea, and Danube-Black Sea basins.
The lighthouse sites were selected taking into account territorial coverage involving all Member States; coverage of the main elements of the water system, working with naturally coherent and continuous ecosystems and covering all three Mission objectives; and building on prior political commitments for basin-scale cooperation and existing capacities and networks.
Each basin aims to address at least one of the objectives as part of Mission Ocean and Waters, and these will be pursued through Lighthouses.
