This chapter argues the need to rethink ‘durable’ solutions to displacement, with emphasis on facilitating refugees’ mobility to enable them to come up with their own transformative solutions. More specifically, it considers whether migration might offer a ‘fourth solution’ to complement the conventional solutions of repatriation, local integration, and resettlement. The chapter suggests that it is important to recognize and contest the inherent ‘sedentary bias’ that characterizes state-centred responses to migration during conflict and crisis. It also highlights the failure to ‘solve’ forced migration by framing the ‘refuge problem’ in terms of physical dislocation, rather than focusing on the denial of the political rights of refugees and internally displaced persons as citizens. Finally, the chapter looks at attempts to implement mobility-focused solutions in West Africa and Afghanistan and the prospects for successful implementation of such a mobility-centred strategy in the face of political hostility towards migration.
