The papers in this collection offer empirical cases that, both historically and geographically, demonstrate the fluxes in the role of borders, legal framework and structures of surveillance in upholding state control over territory and human mobility (cf. Roy, this issue). The shrinking spaces of asylum around the world are now well-documented (e.g. Anderson, 2013; Hyndman and Mountz, 2008). This issue moves beyond just refugees, however, to focus on how migration governance in general is evolving in the 21th century.
