This book covers new conceptual, methodological, and empirical issues that will progress the debates on Vernacular Security Studies (VSS) and the value of studying ordinary articulations of (in)security. Bringing together established and emerging scholars, it offers a timely and much needed engagement with this explicitly critical - and increasingly prominent - framework in security research. Demonstrating its value in different geographical, thematic, and historical contexts these experts consider the impact of VSS on a range of topical issues including multi-species relations, decolonial/postcolonial approaches to security, migration, borders, and cities. This volume will be of great interest to scholars and students engaging with 'bottom-up' approaches in critical security studies or critical International Relations.
