Mountain regions in the Alps and beyond are increasingly shaped by competing land uses and intensifying natural hazards. Tourism development, hydropower and other renewables, hazard mitigation, agriculture, forestry, biodiversity conservation, and settlement expansion all claim limited space and resources. These overlapping claims interact with climate change, socio-demographic shifts, and economic pressures to produce complex land use conflicts and new constellations of risk. Impacts are rarely isolated: they tend to cascade across sectors, scales, and places, raising questions about systemic risk and resilience in mountain socio-ecological systems.

This session invites interdisciplinary contributions that examine how land use decisions in mountain regions generate, redistribute, and transform natural hazard risk and other forms of vulnerability. We welcome conceptual, empirical, and methodological work that addresses (among others):

• Land use conflicts and trade-offs in relation to natural hazards and climate extremes
• Systemic and cascading risks in mountain socio-ecological systems
• Approaches to assessing and governing resilience in the face of interacting pressures
• Modelling and scenario tools (e.g. agent-based models, participatory approaches) for exploring alternative land use and risk futures
• Institutional, cultural, and political dimensions of land use competition and risk management in Alpine and other mountain settings

• Cases where competition was leading to open land use conflicts or where cooperation, negotiation, or adaptive governance strategies prevented an escalation

The session aims to bring together researchers and practitioners from natural and social sciences, engineering, planning, and governance to jointly reflect on how land use competition, natural hazards, and systemic risks can be better understood and addressed. Contributions from different Alpine regions and comparative mountain case studies are particularly encouraged.
