Migration and development are two complex and interrelated issues. While migration is frequently caused by underdevelopment, it may also present a vehicle to foster development and a means of escape from poverty. This collection sheds light on the migration-development nexus seen from many angles, and presents the latest knowledge and research on issues such as migrants' remittances, the development potential of return migration, development questions relating to conflict situations and livelihoods of refugees. Three country studies (Afghanistan, Somalia, Sri Lanka) examine the theories in practice, while some of the articles discuss possible policy options regarding immigration and asylum, development assistance and emergency relief.
