Sustainable tourism is not a static target, but a dynamic process of change, a transition. This book considers how monitoring using indicators can assist tourism to make such a sustainability transition. It encourages the reader to view tourism from a broad, interdisciplinary perspective that draws on material from a wide range of sources including ecology, global change and the new and emerging field of sustainability science. The book explains why monitoring is important for different groups of stakeholders; public and private sector, NGOs and communities. It also examines important monitoring considerations such as what and where to measure, how much will monitoring cost and how the data can be presented. The book puts particular emphasis on indicator use and implementation. It highlights the process and techniques to develop and use indicators and then provides clear and detailed examples of monitoring in practice around the globe at different geographic scales.
