Title Drought, agricultural adaptation, and sociopolitical collapse in the Maya Lowlands Type Journal Article
Year 2015 Publication Proceedings of the National Academy of Sciences Abbreviated Journal Proc Natl Acad Sci USA
Volume 112 Issue 18 Pages 5607-5612
Keywords Maya civilization; drought; societal collapse; climate adaptation; compound-specific isotope analysis
Abstract The Terminal Classic decline of the Maya civilization represents a key example of ancient societal collapse that may have been caused by climate change, but there are inconsistencies between paleoclimate and archaeological evidence regarding the spatial distribution of droughts and sociopolitical disintegration. We conducted a new analysis of regional drought intensity that shows drought was most severe in the region with the strongest societal collapse. We also found that an earlier drought interval coincided with agricultural intensification, suggesting that the ancient Maya adapted to previous episodes of climate drying, but could not cope with the more extreme droughts of the Terminal Classic.
