Study says Mayan civilization was wiped out by drought

A recent study has suggested that the conditions caused by a mild drought might have been the reason for the collapse of the Mayan civilization.


The research published in the journal Nature says a continuous 25 to 40 percent drop in rainfall reduced water supplies in the homeland of the ancient Maya civilization located in what is now southern Mexico and Guatemala.

Researchers at the Yucatan Centre for Scientific Research in southern Mexico and the University of Southampton used modeling techniques in order to estimate the rates of rainfall and evaporation between 800 and 950 CE, the decline period of Maya civilization.

"These reductions amount to only 25 to 40% in annual rainfall, but they were large enough for evaporation to become dominant over rainfall, and open water was rapidly reduced," said Professor Eelco Rohling of Southampton University.

"Societal disruptions and abandonment of cities are likely consequences of critical water shortages, especially because there seems to have been a rapid repetition of multi-year droughts," he added.

Scientists have been analyzing different factors that could have been involved in the collapse of the classic Maya civilization for years offering theories such as social unrest, disease and deforestation.
