Implicit in notions of sustainable development is an holistic triple bottom line approach that seeks to preserve essential ecological processes, protect human heritage and biodiversity and foster inter and intra-generational equity whilst recognising political dimensions of tourism (Hall 2000; WCED 1987). Sustainable tourism seeks to achieve these goals and at the same time meet the needs of tourists and the long-term viability of tourism enterprises without compromising alternative uses or processes (Butler 1993).
