It has been widely accepted that trafficking of human beings is a human rights issue. However, it has been difficult to address the human rights aspects of the phenomenon in practice, because a comprehensive analysis of applicable human rights norms and principles has not been fully developed, and therefore the nature of obligations imposed upon States is not entirely clear. The purpose of this book, then, is to establish a human rights framework to promote better understanding of the multi-faceted problems inherent in trafficking of human beings, articulate obligations imposed upon States, and facilitate a holistic approach. The book also contains chapters on case studies at the national, regional, and international levels, thereby combining the theory and practice.
