civilization collapsed: not due to climate change

Climate change was probably not the sole cause for the collapse of the Harappan civilisation says researchers. The civilization was use to inhibit in the Indus-Ghaggar-Hakra river valleys, and they did not give up despite the decline in the monsoon.

The recent research by a team of researchers from IIT Kharagpur, Institute of Archaeology, Deccan College Pune, Physical Research Laboratory and Archaeological survey of India (ASI) also shows that the civilization itself was much older than thought -- it is at least 8,000 years old.
"Our study suggests that the climate change was probably not the sole cause of Harappan decline. Despite the monsoon decline, they did not disappear. They changed their farming practices and switched from water-intensive crops when monsoon was stronger to drought-resistant crops when it was weaker,” pointed out the researcher.
Our work shows that they did not give up, despite the change in climate conditions," Anindya Sarkar of the Department of Geology and Geophysics, IIT Kharagpur and the lead investigator told the media. "Our study suggests that other causes, like change in subsistence strategy, by shifting crop patterns rather than climate change was responsible for the Harappan collapse," Sarkar said.
In the Indian subcontinent, the major centres of this civilisation include Harappa and Mohenjo-Daro in Pakistan and Lothal, Dholavira and Kalibangan in India. The findings have been published in the journal 'Nature Scientific Report' on May 25.
