As blue growth (widely accepted as the sustainable development in the marine and maritime sectors as a whole) is gaining increasing traction, oceans and seas are seen as new frontiers for global capitalism. In African countries this trend has spurred a new wave of appropriation and control of maritime spaces for the blue economy. At a time of unprecedented expansion of global production and trade, the African continent is facing new challenges in maritime governance. The governance of the seas has profoundly changed in the 21st century with the explosion of maritime transport, the globalization of the exploitation of marine resources, and the growing concern for environmental issues. The idea of an integrated policy of seas and oceans management became a cornerstone of international and national instruments aiming to regulate maritime circulation and exploitation of marine resources. Integrated maritime management policies put emphasis on liberalization of the marine sectors and resources and the security agenda, taken in its broad sense to guarantee freedom of trade and environmental sustainability. These efforts, whose putative purpose is to combine economic, social, and environmental goals, has resulted in an unsteady balance between different sectors, scales, and actors and opened the door to controversies, dissent, and politics. Although the priorities of this global policy agenda continue to transform the maritime governance in Africa, the African states and societies are also actively reshaping it. While African states alter international maritime policies according to their own ends, these are also constantly molded through struggles over norms, resources, and spaces and conflicts arising from the dialectics of possession and dispossession. The text focuses on the four key areas of maritime governance: ports, offshore exploitation, security, and environment. Even though from the perspective of integrated maritime governance these fields are interwoven, they are subject to particular policies. Hence, while focusing on policies in each area separately, it also analyzes their relationships with each other in order to illuminate the complexity of power configurations.
