Study revealed Harappan Civilization collapsed due to Climate Change

A recent study published on 27 May 2012 in the journal Proceedings of the National Academy of Sciences revealed that the Harappan civilization, 4000 years ago, was collapsed due to the climate change. The study suggested 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.
