A study by the University of California, Davis identified a pattern of increasing severity during periods of climate change in the south central Andes from 470 AD to 1500 AD. The study suggests that climate change and competition for limited resources are leading to conflicts among mountain communities in the region.
After analyzing data on skeletal remains and ice deposition, the study’s authors found a strong association between decreased precipitation and increased rates of traumatic brain injury, indicating higher rates of interpersonal violence.
Interestingly, the same trend was not observed in coastal and mid-altitude regions, possibly due to alternative strategies or greater agricultural and economic diversity.
