Fishers are amongst the poorest people in Bangladesh. Most possess few capital assets, many are landless and have few alternative livelihood options. Their access to lakes, rivers and floodplains is strongly affected by decisions made by the people who control aquatic resources at the local level, particularly the rich and elites. The Community Based Fisheries Management Project is an action research project, which the WorldFish Center has been assisting the Department of Fisheries, Bangladesh to implement over the last ten years. The second phase of the project, CBFM-2, has involved the development and testing of a range of community based and co-management models in 116 water bodies through supporting the development of 130 Community Based Organisations (CBOs) in partnership with 11 NGOs. Social capital is one of the five different types of capital (natural, physical, human, financial and social) that are needed for households to develop sustainable livelihood strategies. It consists of the networks and norms that govern the interactions among individuals, households and communities. Social capital can be categorised into three types: bonding, bridging and linking but the boundaries between these vary across contexts. The aim of the study was to see whether poor fishers involved with the CBFM-2 project have benefited through increasing their social capital.
