The contribution of aquaculture and fisheries to gross domestic product (GDP) is one of the most widely used indicators of its economic performance. Despite strong interest in and great efforts made towards assessing the contribution of aquaculture and fisheries to GDP, there is a general lack of understanding or consensus on how to properly measure the sector’s contribution to GDP and effectively use the measures for evidence-based policy and planning for sustainable aquaculture and fisheries development. While a fisheries GDP measure has been included in the Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development (i.e. SDG Indicator 14.7.1: Sustainable fisheries as a percentage of GDP in small island developing states, least developed countries and all countries), it is nevertheless a Tier III indicator for which no internationally established methodology or standards are yet available. This paper contributes to improving the understanding and measurement of aquaculture and fisheries’ contribution to GDP by: (i) using input-output models (including mathematical formulas and numerical examples) to formulate and clarify a set of measures of aquaculture and fisheries’ contribution to GDP; (ii) discussing alternative methods to estimate the measures under data-poor environments; (iii) suggesting an empirical methodology and general guidelines on the estimation and reporting of the measures; and (iv) exploring how to utilize the measures for evidence-based policy and planning. The conceptual framework and empirical methodology suggested in the paper will help move towards internationally established methodology, standards and guidelines on measuring aquaculture and fisheries’ economic contribution.

Ocean margins are the transitional zones between the oceans and continents. They represent dynamic systems in which numerous processes shape the environment and result in impacting the utilization and hazard potentials for humans. These processes are influenced by a variety of steering mechanisms, from mountain building and climate on the land to tectonics and sea-level fluctuations in ocean margins. This book examines various aspects of regulation for the long-term development of ocean margins, of the impact of fluids and of the dynamics of benthic life at and below the seafloor in ocean margin systems.

The world is regularly confronted on television and in other mass media with dramatic images of African boat migrants. Seemingly desperate, these Africans, most of them males, are willing to risk a perilous journey at sea, hoping for a better life in Europe. And, even worse, hundreds more are believed to die each year, swallowed up anonymously by the choppy waters off Africas coast. This book focuses on fishermen who have played a pivotal role in boat migration from Senegal to Spains Canary Islands, advancing various reasons for the fishermens prominent role. Besides their long history of migration, their proven experience with navigating, their familys push and investment, their perceptions and ideologies about Europe, there is also their growing marginalization as a result of the deepening crisis in the Senegalese fishing sector and the inadequate policies of the Senegalese government that prevents them from having good prospects of improving their standards of living. The book provides deep insights into the meaning of boat migration, and on the effects of success or failure on the migrants and their families. It goes beyond the usual economic explanations to convincingly situate boat migration within the long-standing West African culture of migration, and highlight the significance of socio-cultural and political factors. Among the fascinating findings are the perception of migration as status enhancing and a rite de passage in the Senegalese fishing communities, and the profound roles of the extended family, social networks and, above all, religion, especially the widespread influence of the marabout. The importance of information and communication technologies in sustaining transnational networks is equally highlighted.
