The purpose of these Policy Briefs is to ensure effective dissemination of information collected and generated as a result of the World Bank-funded Study of Good Management Practice in Sustainable Fisheries, the ACP Fish II Feasibility Study (EC), and a Workshop on Fiscal Reform in Fisheries (DFID and GTZ). This Policy Brief 9, discusses resource rent which is a key concept in the management of fisheries as it refers to a source of considerable wealth, potentially or actually available to society. Resource rent generated in fisheries can be a critical contributor to sustaining effective fisheries management, and can contribute to government revenue and to the wealth and wellbeing of society. If its potential is not well understood and there are no limits on fishing effort, this wealth will not be realised. Potential resource rents of great value can easily be squandered on excess capacity, leading to depletion of fisheries resources. Namibia, which became independent in 1990, is a good example of successful fisheries management leading to the generation and capturing of resource rent of significant value.
