Ecological footprint analysis as a tool to assess tourism sustainability

This article has the aim to provide a methodological framework for the calculation of ecological footprints related to leisure tourism. Based on the example of the Seychelles, it reveals the statistical obstacles that have to be overcome in the calculation process and discusses the strengths and weaknesses of such an approach. As many tropical island-states depend heavily on foreign exchange earnings derived from visitors arriving by air, special attention is paid to the use of energy associated with air travel. Furthermore, implications of the findings for national greenhouse inventories are discussed. Finally, as the Seychelles have safeguarded a wide range of ecosystems in protected areas, which are for their existence ultimately dependent on financial resources derived from tourism, the question is raised if long-distance travel can be a means to safeguard biodiversity.
