This book provides a comprehensive introduction to the essential concepts of environmental conflict and peacebuilding by compiling and explaining key terms in an easy-to-navigate A-Z format.Over the past 80 years, scholarly interest in war and peace has flourished, resulting in the institutionalization of disciplines such as international relations, security studies, and peace and conflict studies. Since at least the 1970s, research has also investigated the planetary effects of global environmental change. Environmental peacebuilding emerged at the intersection of environment, conflict, and peace, weaving together several related threads that address both environmental risks of conflict and environmental opportunities for peace. The language used to describe, explain, predict, teach, negotiate, and form policy in the arena of environmental peacebuilding is often nuanced, evolving, and contested. This book fills a gap in the literature, by providing a more consistent understanding and approach to key aspects of environmental peacebuilding. The book begins with a thematic introduction to contextualize the topic, written by a team of world-leading scholars. The book then follows an A-Z format, with over 150 entries from experts in the field describing and explaining key concepts, and providing examples of how different terms are applied within this growing discipline.This comprehensive A-to-Z guide will be useful for students, academics, professionals, and policymakers seeking a wider understanding of environmental peacebuilding. The book will also be useful for those studying security studies, peace and conflict studies, environmental studies, and environmental law.
