The European Alpine region is one of the most sensitive to climate change impacts. ClimAlpTour is a European research project of the Alpine Space Programme, dealing with the expected decrease in snow and ice cover. The research reported herein analyses the municipality of Auronzo di Cadore (22,000 ha) in the Dolomites. The local economy depends on tourism which is currently focused on the summer season. Since recently the Community Council is considering options on how to stimulate a further development of the winter tourism. This paper refers to a prototype agent-based model, called AuronzoWinSim, for the assessment of alternative scenarios of future local development, taking into account complex spatial and social dynamics and interactions. Different typologies of winter tourists compose the set of human agents. Climate change scenarios are used to produce snow cover projections. AuronzoWinSim is planned for use in a participatory context with groups of local stakeholders.
