Several initiatives have been taken worldwide to promote international coordination and integrated approach in marine management. At the European level, ten years after the adoption of the Marine Strategy Framework Directive (MSFD), the Member State strategies still present some ecological, economic and social challenges. This review identifies the minor, intermediate and major impediments (respectively defined as ‘bottlenecks, showstoppers and train-wrecks’) to marine management, resulting from a 4-year analysis of national, regional and European reports. Most of the problems are linked to the resistance of countries to collaborate and to the inability to integrate the work already carried out under other pieces of legislation. The European countries will need to better integrate and coordinate their actions in marine management in the second cycle of the MSFD, in order to achieve its final goal of Good Environmental Status as well as the objectives of other environmental policies.
