Tourism research: Water demand by the tourism sector

Abstract

Within the context of a study of the scenarios of global change, a quantification of the water demands by the tourism sector that were as precise as possible and at the best possible spatial resolution was undertaken. Whether the water demand by the tourism sector is reconcilable in the sustainable long term can be estimated from this quantification. The facilities were located on points and associated with unique proxels in order to be able to carry out the spatial distribution of the water demand by the tourism sector with DANUBIA (In this way, the spatial distribution of the tourism facilities could be transferred to the model. The tourism research subproject basically follows a supply-oriented approach for creating a model. This means that elements of the tourism infra- and suprastructure facilities are treated as actors in the model that can be influenced by the environment and are responsible for the tourism water demand. At present, the content of the Tourism model consists of three subcomponents: the “DeepTourism� component, the Attractiveness model”� and the Water consumption model�. The demand for drinking water by the tourism sector is quite heterogeneous is space and time. Particularly high demands occur in the Alps and as a whole in the region of Munich. Overall, it can be concluded that there is a slight overestimate in the calculation of the demand for drinking water by the tourism sector.
