The paper reflects on fieldwork conducted since 2000 with displaced communities in Lower and Middle Casamance, Senegal, amid arguably West Africa's longest-running civil conflict. While this is a small conflict in a geographically confined space, Casamance presents a microcosm of dynamics common to other displacement situations in Africa. In this context the paper explores how the understandings, lived experiences and practices of the displaced transcend normative categories used by aid actors to define and manage such situations. Five thematic areas are examined: enumeration of the displaced; complex mobilities, both rural-urban and transnational; historiographic understandings of displacement; political manipulation of displacement situations; and the dynamics of return and reconstruction. The paper concludes by summarising failures of understanding in these areas among much of the aid community, and their consequences. It argues that well-grounded and socially nuanced understandings of displacement may inform more effective aid interventions and enhance the peace process.
