This issue of Policy Matters is titled, "Exploring the Right to Diversity in Conservation Law, Policy, and Practice". Thirty-five articles and 4 book reviews from a variety of countries in Africa, Asia, and the Americas explore initiatives of duty-bearers, initiatives of rights-holders, and challenges and opportunities presented by the law, policy, and practice of rights-based approaches in topical themes such as protected areas and ICCAs, forests and REDD, and the protection of traditional knowledge and customary ways of life. Holly Shrumm, Editor-in-Chief, gratefully thanks all peer reviewers, peer editors, and authors for their dedicated efforts over the past several months.
