An archaeological study from UC Davis suggests that there may have been competition for limited resources. Climate change in current times has created problems for humans such as wildfires and reduced growing seasons for staple crops, spilling over into economic effects. Numerous studies have both
New research links historical climate change in the Andes to increased violence, highlighting the vulnerability of people in marginal environments to current and future climate impacts.
Climate change and potential competition for limited resources in the south-central Andes likely led to violence among people living in the highlands at that time, researchers suggest in a new paper. Their study looked at head injuries of the populations living there at that time, a commonly used proxy among archaeologists for interpersonal violence.
The study was published June 5 in Quaternary Research, Cambridge University Press. The co-author of the paper is Randall Haas, formerly of the same lab at UC Davis and currently a professor at Wayne State University.The same results were not found in coastal and mid-elevation regions, indicating they chose nonviolent solutions to climate change or were not affected by it, researchers said.
