The objectives of this Technical Paper are to highlight the contribution that inland and coastal small-scale fisheries can make to poverty alleviation and food security and to make practical suggestions on ways that this contribution can be maximized. This paper is organized into three main sections. The first section discusses the concepts of poverty, vulnerability and food security, and briefly outlines how these concepts have evolved in recent years within the field of fisheries (in line with the rest of the development literature). The second section reviews the actual and potential contribution of small-scale fisheries to poverty alleviation and food security. It illustrates, through use of examples, the role that small-scale fisheries can play in economic growth at the national level and poverty alleviation and rural development at the local level. The third and main section of the document discusses ways of increasing the contribution of small-scale fisheries to poverty alleviation and food security.
