Evolution of water resources in the Bajo de Sarmiento extraandean Patagonia natural and anthropogenic impacts

This research paper examines the hydrogeomorphological dynamics of the Bajo de Sarmiento in extra-Andean Patagonia, analyzing how the combination of long-term climatic variability and human activity has impacted water bodies from the Holocene to the present.

• While climatic variability, specifically aridity prevailing since the middle Holocene, has historically been the primary driver affecting water body dynamics in the region, human activities based on local social perceptions of resources have intensified these effects over the last 120 years.
• The combined impact of climate and human activity has resulted in the basin shifting from an exoreic to an endoreic regime and caused one of its lakes to recede to the point of nearly disappearing by 2016.
