Book excerpt: This Handbook provides a state-of-the-art analysis of the critically important links between migration and security in a globalising world, and presents original contributions suggesting innovative and emerging frontiers in the study of the securitization of migration. Experts from different fields reflect on their respective conceptualisations of the migration-security nexus, and consider how an interdisciplinary and multifaceted dialogue can stimulate and enrich our understanding of the securitisation of migration in the contemporary world.
