Fully revised and updated in its third edition, this timely book brings together the study of conflict and war and the problems surrounding economic development of developing societies who are most prone to experiencing problems in moving on after war. The book does so by reflecting on the issues surrounding war as it unfolds and after it has (in principle) ‘ended’, within the context of the history, present day problems and future prospects. The book aims to highlight the possibilities, successes and failures of past and present policies that bring ‘development’ to countries and peoples that want to be more involved in deciding their own futures after conflict and war, and often find themselves subject to what can be seen as arbitrary and even alien ways of thinking and acting by institutions in which they theoretically have membership and agency but often do not in practice. The case studies have been fully updated to reflect changes and developments since the second edition of this text and there are questions at the end of each chapter to promote reflection. This new edition presents a deeper dive into the history of conflict and the emergence of new theories and policy guidance about present and future options in the fields of conflict and development. Accessible and engaging, this textbook is a pivotal resource for a nexus of subjects related to the often separated fields of conflict and development studies, as well as practitioners in this area.
