Extreme Climatic Events as Drivers of Ecosystem Change

Extreme climatic events played a pivotal role in the decline of Anasazi culture in the Four Corners region, including the abandonment of Mesa Verde's cliff dwellings by the late 13th century. The study reveals that population shifts and cultural changes were driven by environmental pressures, such as prolonged droughts, which disrupted agricultural practices like maize farming on semi-arid mesa tops. Research analyzed historical occupation patterns, construction activity, and climate data to link these extreme events to the decline of large population centers, including multi-storey great houses in the San Juan Basin. The findings highlight the vulnerability of human societies to climatic variability, offering insights into the resilience and adaptation strategies of prehistoric communities.
