In line with the decisions of the 19th ICE, the main aim of this handbook is to provide a step-by-step guide on how to mainstream the Blue Economy into continental, subregional, and national policies, plans, laws, regulations, and practices for the development of African sustainable Blue Economy strategies. It targets African States, Regional Economic Communities (RECs), Regional Seas Conventions, and intergovernmental organizations (IGOs). Therefore, the Blue Economy Policy Handbook intends to raise the level of understanding of the Blue Economy concept by all relevant stakeholders, including African island, coastal, and land-locked States, in pursuit of structural transformation, sustainable economic growth, and enduring societal progress.
