New research from IIT Gandhinagar reveals how a series of prolonged droughts spanning over 85 years forced the abandonment of major Indus Valley cities like Harappa and Mohenjo-Daro. By analyzing paleoclimate records and employing advanced climate models, scientists demonstrate how declining monsoon patterns and water scarcity gradually transformed one of the world's earliest urban societies, offering valuable lessons for modern climate adaptation strategies.
