The researchers found that many settlements were affected by drought linked to
major climate fluctuations. “Geographic factors and technologies introduced by
humans played a big role and influenced societies’ options for development as
well as their particular ways of dealing with drought,” said the team leader
The findings of the study indicated that agriculture flourished and urban
civilisation thrived in normal conditions with proper rain and availability of
water for irrigation. But with rainfall became sporadic and irrigation became
unreliable, agriculture collapsed and cities were abandoned and, thus, some of
the great civilisations faced their end.
Earlier studies also hinted that long term draught, began in 2000 BC, led to
decline of many ancient civilizations in the Persian Gulf and the Indus River
Based on isotope data from the sediment of an ancient lake, a research carried
out by the University of Cambridge and India’s Banaras Hindu University
suggested that a series of droughts lasting over a period of 200 years was
probably responsible for the decline of the great Bronze Age urban civilization
of Indus valley.
In present Pakistan and northwest India, Indus Valley was home to the dead
Harappan Civilization characterized by large, well-planned cities with advanced
municipal sanitation systems.
Research conducted by Yama Dixit, a paleoclimatologist at the University of
Cambridge, UK, and her colleagues suggested a link between the gradual decline
and change in climate basing upon isotopic data and evidences obtained from the
dried up bed of Kotla Dahar, an ancient lake 40 miles east of the north-eastern
edge of the Indus Valley area in Haryana, India.
These findings can give environmental scientists and archaeologists some clues
about how early agrarian societies dealt with climate fluctuations and varying
local environments. “They can also help evaluate current conditions in regions
with a high risk of crop failures,” Riehl adds.
The findings are like warning calls to every one of the present society and to
the leaders across the globe in particular because the earth is undergoing
climatic threats which, probably, are similar to those existed in the prologue
of collapse of some of the classic civilisations.
More than our predecessors, we are adding power to the threats by prioritising
comfort against the nature and emitting more heat and Green House Gases by
undertaking projects for large industries and urbanisation.
It’s now up to us if we should be judicious while listing the menu for our
comfort and sincerely work to save the earth for the future generations or make
