Despite the emergence of various marine and coastal governance approaches to address the effects of human activities within the marine environment, conflict continues. This conflict could derail attempts to achieve blue growth and conservation policies, as well as the United Nations Sustainable Development Goals. But, perhaps now that we have a better understanding of the causes of conflict, and how existing approaches address such causes, we can start to make changes to governance as required to prevent such conflict. This chapter provides a brief recap of all previous chapters. It then outlines what the findings of this book mean for the policies of blue growth and conservation specifically, within the framework of the Sustainable Development Goals. The chapter ends with some implications for theory and, conceivably more importantly, for practice in the prevention of marine and coastal conflict.
