Resumen
This paper aims to explore the topic of sustainable tourism activity. The subject has emerged in the last two decades from discussions about the content of the report, Our Common Future. The decision to transform developing countries into new offerings for ecological and cultural tourism brings to the discussion the imprecise and conflicting definitions of the concept and the need to distinguish between the development of tourism, and sustainable tourism supported on the principles of sustainable development. The research reviews the environmental and social contexts of the Oecusse-Ambeno region in East Timor. It discusses the new sustainable tourism activities in the region with the need to ensure that the concept includes a strong base of perceived authenticity in the human context and the physical environment. The problems of the carrying capacity control of tourism development, and the term?s relevance to mass or conventional tourism, are strategically anticipated. The region is confronted with an offer that supports more peacefulness, and that is more aligned to the culture and the natural environment. This paper provides insight into the ways in which tourists perceive the authenticity of visitor attractions and highlights the importance of the cultural and environmental values of tourism destinations for strategic planning and marketing purposes.
