Climate Change triggered the Collapse of Harappan Civilization

Mon 04 Jun 2012

According to a recent study published in the journal Proceedings of the National Academy of Sciences on 27 May 2012 the Harappan civilization, 4000 years ago, collapsed due to the sheer change in climate. The study reveleded that decline in monsoon rains led to weakened river dynamics, and played a critical role both in the development and the fall of the Harappan culture which relied on river floods to fuel their agricultural surpluses.

The researchers found out that Harappan civilization, one of world’s largest and earliest urban civilizations, covered an area of more than 386000 square miles (1 million square kilometers), extending over plains of the Indus River from the Arabian Seato the Ganges. It was believed that 10% of the world population resided in the civilization.
