This study adopts a participatory approach to characterize Hydrosocial Territories (HST) in the Upper Valdivia River Sub-basin, aiming to identify territorial patterns and power relations that shape water governance. By integrating hydrosocial theory with geospatial and social network analysis, the research provides a comprehensive understanding of the socio-ecological dimensions of water systems in a context of megadrought and climate change. The methodology combines qualitative and quantitative approaches, including content analysis, review of legal frameworks, geospatial and geoeconomic analysis, semi-structured interviews with key stakeholders—including community leaders, indigenous groups, and women’s organizations—focus groups, and participatory workshops using the World Café methodology. Direct field observations and engagement in local events further enrich the data collection process. This research identifies key governance structures, institutional norms, and negotiation spaces that influence water access and distribution, facilitating the development of socially acceptable, cost-effective, and contextually relevant adaptation strategies. By emphasizing the role of local knowledge and community participation, this approach enhances informed decision-making and promotes more equitable and sustainable water management practices. Additionally, the findings contribute to policy recommendations that strengthen territorial planning and resilience strategies in hydrologically vulnerable areas.
