This chapter summarises the key findings of the report and offers a set of recommendations to strengthen international co-operation in the sustainable management and development of the ocean economy of the future. It puts forward a working definition of the ocean economy which encompasses not only the ocean-based industries but also the natural assets and ecosystem services that the ocean provides. Focusing on the ocean industries, the chapter outlines the findings of the OECD Ocean Economy Database and briefly presents the estimates of the current value added and jobs provided by the ocean economy worldwide. Turning its attention to the future, the chapter describes the principal forces driving the ocean economy forward, and estimates value added and employment in the global ocean economy by 2030. The results suggest rapid growth of most ocean industries over the next couple of decades, putting increasing strain on the ocean environment and its resources and posing significant challenges to ocean management. The chapter ends by proposing a set of recommendations for governments, business and research which could significantly enhance sustainable ocean management.
