Prato Valentino 2050 project, led by Associazione Val.Te.Mo. in collaboration with Ge.S.Di.Mont. Research Center at the University of Milan (UNIMONT) and the Department of Sociology at the University of Milan Bicocca, aims to develop a long-term strategy for the sustainable transition of Prato Valentino, a small ski resort in the Italian Alps, facing increasing challenges due to climate change. Historically dependent on winter tourism, the area is experiencing declining snowfall and rising temperatures, necessitating a shift towards a more diversified, year-round tourism model. The project’s objectives include fostering a participatory co-creation process with local stakeholders to define a shared territorial vision for 2050, promoting sustainable outdoor and slow tourism alternatives, enhancing local socio-economic resilience. The project is developed by integrating expertise and best practices from international initiatives such as the Alpine Space TranStat project. The methodology follows a multi-phase approach: (1) data collection and analysis of environmental, economic, and tourism dynamics, (2) stakeholder network analysis and community mapping, (3) participatory workshops to co-design future scenarios, (4) formulation of an integrated strategic roadmap, and (5) communication and knowledge transfer through webinars, local events, and transnational collaborations. By fostering a science-based and community-driven approach, the project seeks to provide a replicable model for Alpine regions adapting to climate-driven transformations in the tourism sector.
