The book examines new frontiers in the implementation of constitutional, international, and regional rights-based approaches to promote environmental protection. The contributions collected here represent the research of scholars from across the globe who were invited to participate in a Symposium on New Frontiers held at North-West University in South Africa in April 2016 by Professors Erin Daly (Widener University Delaware Law School), Louis Kotzé (North-West University Law Faculty), and James May (Widener University Delaware Law School), and doctoral candidate at the North-West University Law Faculty, Caiphas Soyapi. The symposium was made possible through generous funding by the Konrad Adenauer Foundation. We hope that this publication will help to further the global conversation on comparative environmental rights-based approaches among policy-makers and governments, practitioners, non-governmental organizations, civil society, scholars, educators, and post-graduate students. Finally, we are most grateful to all our contributors from all over the world for sharing their research and work with us. Without them, this publication would not have been possible.
