With contributions from Sámi and non-Sámi scholars from Arctic regions, this book provides new insights into our understanding of the significance and legal protection of sacred sites for Sámi of the Arctic. It examines the role of international human rights, environmental law, and longstanding customary law that uphold Arctic indigenous peoples’ rights in conservation, and their associated management systems. It also demonstrates the complex relationships between indigenous knowledge, cultural/spiritual values and belief systems and nature conservation. The book looks forward to providing guidelines for future research and practice for improved integration of the ethical, cultural and spiritual values of nature into law, policy, planning and management. As such, this book offers a contribution to upholding the sanctity of these sites, their cultural identity and the biodiversity associated with them.
