This book is intended as an introductory text from senior undergraduate level up, to be used in courses on international studies and relations, political studies, history, human geography, anthropology and human ecology, futures studies, applied social studies, public health, and other fields. It represents in a coherent fashion the new subject of human security and sets it apart from more traditional models of security. Its approach is deliberately multidisciplinary and transcultural. In addition to a thorough overview of the human security concept, the chapters address problems and opportunities in international law, politics, international relations, human ecology, ethics, law enforcement, development aid, human rights, and public health. The reader is also introduced to specific human security regimes that address human rights violations, peace building and conflict resolution, as well as global environmental governance. The book encourages a vision of the future that acknowledges the certainty of change, extrapolates significant current trends, and questions the values, beliefs and ideals that tend to inform dominant notions of development. Because of its transdisciplinary approach, the book will appeal to a very wide range of interests at the post-secondary/tertiary level. It will be of particular interest to college and university undergraduate students as well as graduate students and researchers, and also to educators from various disciplines in the natural sciences, social sciences, and humanities.
