This book brings together research on various aspects of environmental migration in the context of international law, with a particular focus on the emergence and development of regulation in the field of environmental migration at the global and regional levels. It discusses a theoretical framework for international regulation of environmental migration, analysing the notion and legal status of environmental migrants, categories of environmentally displaced persons, problems of legal regulation in the field of environmental migration at the international level, as well as specific circumstances of international labour migration induced by environmental factors. The annexes here bring together the most important international acts governing various aspects of forced and labour migration. As such, the book will appeal to international law experts, students, post-graduate students, researchers, and the general reader interested in international migration law.
