The planet's most fascinating and yet tantalisingly under-researched component is now a rapidly growing tourism frontier. The sea attracts millions of tourists annually with its diverse array of exclusive activities, but its sheer size brings with it considerable problems for management. Within the context of other economic activities that may compromise the success, if not the very existence of marine ecotourism, this text examines the wide range of marine ecotourism resources, not only natural, but also cultural and man-made. Covering economic, marketing planning and regulation issues, this book also considers the vital role of marine ecotourism in raising awareness of the significance of the seas and oceans to sustainable coastal livelihoods. At a time of great concern over the effects of climate change and high profile issues such as depletion of fish stocks and oil spillages, the insights this book provides are essential reading.
