One Earth Future, through its programs OEF Research, Oceans Beyond Piracy, and Secure Fisheries, presents a unique effort to measure and map intersecting issue areas in maritime security in sub-Saharan Africa. The Stable Seas Maritime Security Index investigates how complex challenges like illicit maritime activity, coastal welfare, and capacity-building overlap, requiring international and regional cooperation. Linkages among various maritime threats are highlighted by combining quantitative measures with close examinations of important case studies from across the region.
