Book excerpt: This edited collection goes beyond the limited definition of borders as simply dividing lines across states, to uncover another, yet related, type of division: one that separates policies and institutions from public debate and contestation. Bringing together expertise from established and emerging academics, it examines the fluid and varied borderscape across policy and the public domains. The chapters encompass a wide range of analyses that covers local, national and transnational frameworks, policies and private actors. In doing so, Migration, Borders and Citizenship reveals the tensions between border control and state economic interests; legal frameworks designed to contain criminality and solidarity movements; international conventions, national constitutions and local migration governance; and democratic and exclusive constructions of citizenship. This novel approach to the politics of borders will appeal to sociologists, political scientists and geographers working in the fields of migration, citizenship, urban geography and human rights; in addition to students and scholars of security studies and international relations.
