This interdisciplinary study addresses the complex dynamics of anthropogenic climate change and hydrological processes in Northwest Patagonia, focusing on the tributary rivers integral to the region's aquaculture sector. Unprecedented droughts since 2010, coupled with evolving climate trends towards a warmer and drier climate (30-50°S), necessitate a comprehensive understanding of hydrological impacts. The research aims to inform water policy through three key objectives: assessing hydrological drought effects on key rivers using 33 metrics and the VIC model, conducting a collaborative risk analysis considering exposure, climate hazard, and vulnerability, and evaluating the economic costs and benefits of implementing Secondary Environmental Quality Standards (NSCA) in tributary rivers. A robust methodology encompasses high-frequency monitoring, GCMs projections, and economic impact assessments. Collaborating with Chilean research centers and international partners like ICRA, the study emphasizes interdisciplinary cooperation. An outreach program targets diverse audiences, fostering communication of findings and highlighting the reciprocal relationship between science and society. Ultimately, this research seeks to enhance the resilience of Northwest Patagonia's aquatic ecosystems, contributing to informed water policies aligned with Chile's Long-Term Climate Strategy.
