This volume offers a rigorous and interdisciplinary exploration of how the European Union's externalization of migration governance has reshaped territorial, political, and human landscapes at its periphery. Tracing the aftermath of the 2015 migration crisis, the volume examines how informal agreements with Turkey, Libya, Tunisia, and Albania initiated a cascading logic that normalizes legal opacity, erodes accountability, and institutionalizes human rights violations. Moving beyond legal and geopolitical critique, the book investigates the entanglement of migration containment with tourism development in border regions such as Lampedusa and Lesvos, exposing how these territories become doubly burdened as sites of both securitization and commodification. By engaging with law, postcolonial theory, and critical tourism studies, the authors reveal the neo-colonial dynamics underlying EU mobility governance and advance alternative models grounded in accountability, territorial justice, and the defense of fundamental rights.
