The blue economy, comprising coastal and marine resources, offers vast benefits for sub-Saharan Africa: of the 53 countries and territories in the region, 32 are coastal states; there are 13 million sq km of maritime zones; more than 90% of the region’s exports and imports come by sea; and the African Union hails the blue economy as the ‘new frontier of African renaissance’.Despite their importance, the region’s coastal and marine resources have been neither fully appreciated nor fully utilized. They are only now being recognized as being key to Africa’s potential prosperity. As the region grows, it has, in general, not taken adequate safeguards to protect these valuable resources. That is partly because some of the problems (pollution, for example) are regional and know no borders. All too often, short-term gains are made at the expense of the long term (overfishing, for example). This book provides, for the first time, a study of the constraints and opportunities the blue economy offers for sub-Saharan Africa. It includes an introduction and overview; sectoral analyses (including tourism, fisheries, mineral resources, culture, shipping and maritime safety); country case studies; and analyses of regional and international efforts towards better coastal zone and marine management.

Sub-Saharan Africa is vastly diverse, and the 49 countries of the region range significantly in terms of population, size and economic scale. The region also differs in topography, climate, history, culture, languages and political systems. Given this vast diversity, it is, accordingly, difficult to draw general conclusions about the continent’s economic performance as a whole. Additionally, the lack of current statistics for several countries makes it difficult to make accurate assessments of economic conditions. Nevertheless, some broad comparisons can be made: of the world’s developing areas, sub-Saharan Africa has the worst record in virtually all of the most important social and economic indicators: the region has the lowest gross national income per head, the lowest life expectancy at birth, the lowest youth literacy rate, the highest rate of adult HIV infection and the highest number of children not living past five years of age. This volume begins by examining recent economic developments and trends. It then looks at the major economic constraints the region has faced in recent years, breaking down those constraints as either ‘external’ (e.g. terms of trade) over which the individual countries have but limited control, or ‘internal’ (e.g. governance and economic policy), over which there is more control. The book concludes by arguing that, despite the notable challenges cited above, sub-Saharan Africa is poised for a transformation, based on closer regional economic co-operation, a growing middle class, increased demand for locally produced goods and services, and a young population.
