On the occasion of the MARE Conference 2017, MERCES WP1 work was presented. The 9th People and the Sea conference explored the nature of maritime mobilities and the ways climate and environmental change, economic development and maritime activities are affecting their direction and volume. Topics to be addressed are: How are maritime mobilities linked and regulated? What are the distributional effects for different maritime activities, and coastal and port communities? How to design innovative governance arrangements that can foster sustainable maritime mobilities?
