Book excerpt: In 2015, the General Assembly of State Parties to the World Heritage Convention passed a ground-breaking Sustainable Development policy that seeks to bring the World Heritage system into line with the UN’s sustainable development agenda (UNESCO 2015). World Heritage and Sustainable Development provides a broad overview of the process that brought about the new policy and the implications of its enactment. The book is divided into four parts. Part I puts the policy in its historical and theoretical context, and Part II offers an analysis of the four policy dimensions on which the policy is based – environmental sustainability, inclusive social development, inclusive economic development and the fostering of peace and security. Part III presents perspectives from IUCN, ICOMOS and ICCROM – the three Advisory Bodies to the World Heritage Committee, and Part IV offers ‘case study’ perspectives on the practical implications of the policy. Contributions come from a wide range of experienced heritage professionals and practitioners who offer both ‘inside’ perspectives on the evolution of the policy and ‘outside’ perspectives on its implications. Combined, they present and analyse the main ideas, debates and implications of the policy change. This book is key reading for all heritage professionals interested in developing a better understanding of the new Sustainable Development policy. It is also essential reading for scholars and students working in the area.
