"Environmental Security remains the most comprehensive volume on the topic, with contributions from leading thinkers in the field collectively providing a comprehensive and critical overview of key issues and debates."Professor Jon Barnett, The University of Melbourne"Environmental security is increasingly invoked but rarely addressed as systematically and expertly as in this text. The topics and authors are carefully selected to properly represent this diverse subject area and the refreshing of this process for this second edition ensures that this important book more than maintains its currency."Peter Hough, Professor of International Relations, Middlesex University, London"This timely book provides an important in-depth analysis and overview of the field of environmental and climate security and is an essential guide for both novice and established scholars and practitioners working on climate security."Judith Nora Hardt, Centre Marc Bloch, Berlin
