This book presents a comprehensive study of the role that the Blue Flag beach program has played around the world, considering economic, social and environmental perspectives. Since its creation in the 1980s, The Blue Flag program awards the management of beaches and marinas based on sustainability, services and quality of their management. To date there are currently close to five thousand awards around the world. Forty years on from the program's creation, this book provides a thorough evaluation of the program, to understand how it has evolved over time, the successes it has enjoyed and the challenges it has overcome, and may face in the future. As an international program, this book reflects the global nature of this program and actively discusses, examines and assesses the different realities and challenges faced by different countries around the world, drawing on case studies from across Europe, North America, Latin America, Africa and Asia. It examines the impact of the award on economic growth, from local to national, environmental protection and education, the development of sustainable tourism, and the sustainable management of beaches. The volume also contributes to emerging debates surrounding the certification of natural resources, where the Blue Flag program has been a pioneer in this field. This book will be of great interest to students and scholars of sustainable tourism, environmental economics, coastal and beach management, environmental conservation and sustainable development.
