Spatial and Developmental Policy Directions Affecting Marine Spatial Planning in the Northern Aegean Sea, Greece.

European strategic policy directions toward a sustainable blue economy have strengthened interest in maritime investments, thus increasing sectoral competition for marine space. Emerging repercussions out of such a rising interest need to be handled by marine spatial planning (MSP) as a means of properly allocating marine space to diverse uses; managing conflicts and promoting synergies among them; and pursuing a multi-use perspective of this space. A critical stage of each MSP exercise is the exploration of land- and marine-based policy directions and their current or potential repercussions in the marine environment. Such an exploration is carried out in this work by means of a qualitative policy review for informing the MSP process in the Northern Aegean Sea, Greece. By delving into diverse policy frameworks at various spatial levels—i.e., local (urban), regional, and national/European—constraints, but also perspectives in policy choices/maritime uses in the MSP context, are identified, thus guiding more informed MSP choices in the specific study region while attaining a successful integration or coordination between land and marine developments.
