Abstract: This study analyzes precipitation and temperature projections in the regulated Chili system using the SSP 1.26 and SSP 5.85 climate change scenarios from the CMIP6 Global Climate Models. Statistical bias reduction methods were applied using empirical quantile mapping for 13 sub-basins, based on historical data gridded from the PISCO product. The results indicate an increase in precipitation and temperature by 2100, with larger increases in high altitude areas under both scenarios. In the SSP 5.85 scenario, the projected changes are more pronounced, suggesting an increased risk of extreme weather events. These findings underscore the need to adapt water infrastructure and water management policies in the basin to mitigate the impacts of climate change. Nature-based solutions, coupled with conventional infrastructure, could be key to improving water resilience in the region.
