In the current world disorder, security is on everyone's lips. But what is security from a cross-cultural perspective? How is it imagined and experienced by people on the ground? Crucially, what visions of the future are at stake in people's potentially divergent concerns with security: what, and when, is the time of security? Exploring diverse notions and experiences of time involved in security practices across the globe, this volume brings together a selection of international scholars who conduct ethnographic research in a broad ambit of securitized contexts – from the experience of Palestinian detainees in Israel or forms of popular violence in Bolivia, to efforts to normalize social relations in post-conflict Yugoslavia and ways of imagining threat in left-radical protest movements in Northern Europe. Interrogating recent debates about the role of "securitization" in contemporary politics, the book paves the way for novel forms of security analysis at the crossroads between anthropology and political science, focusing on the comparative study of the temporalities of securitization in a multi-polar world. Offering a pioneering synthesis, the book will be of interest not only to anthropologists, but also to students and scholars in political science and the growing field of Security Studies in International Relations.
