Mountain huts play a crucial role in supporting sustainable tourism and facilitating safe access to high-altitude environments. Through the European Mountain Association (EUMA) database, which gathers data from 36 member associations and represents 3,266,106 individual members, we analyze the distribution, utilization, and maintenance needs of almost two thousands huts across Europe. By leveraging a federated data architecture, this study provides an integrated perspective on hut infrastructure and its role in adapting to climate change. The collected data with other open data source (like natural spring) allow for identifying maintenance priorities and environmental impacts, helping both policymakers and local managers implement evidence-based strategies for sustainable mountain tourism. With increasing pressures from climate change, understanding the dynamics of these essential infrastructures is vital for long-term resilience. This poster will highlight key statistics derived from the database, demonstrating how open data and digitalization contribute to optimizing hut management. Excerpt:
