L’uso del Telerilevamento satellitare per una corretta analisi degli impatti ambientali del turismo, nel Parco Nazionale del Sagarmatha (Nepal).

A broad definition of tourism may be the moving of people from one place to the another and between different countries too. The consequence is the participation of trades, governments and single persons which have to provide all necessary services. The main elements for the developing of tourism business are: the per capita income growing, the technological communication increasing and the largest availability of free time for holidays. We can consider other factors for touristic needs too as: a physiological, cultural and religious requirement to satisfy own wishes; the belief that it’s necessary to visit a specific place to gratify a specific condition and finally the economic availability. An important point of attention is the quantitative and qualitative decreasing of natural touristic resources. This is due to urban spreading and to environmental impact of touristic activities too. The Sagarmatha National Park with its grandiose landscape views, the highest peaks in the world and the local cultural tradition lends to an elitist tourism of climbers and trekkers. The price to be paid for it is high in terms of economic and natural resources. This study aims to begin to analyze the outer dis-economies in the touristic integrated offer in this geographic area. The adopted methodology proposes multi-temporal remote sensing techniques as a tool for understanding the environmental impacts. We hope to contribute to know more about the natural response to touristic impact and to facilitate the land-use planning for bio-potential index increasing. These actions are effective if we consider to support the local Sherpa communities and their quality of life.
