• As per some scholars, the reason for the decline is the change in the course of River Ghaggar-Harka that had led to an increase in the aridity of the place. Around 2000 BC, there was found an increase in arid conditions. The location where the Indus valley civilization once flourished is a desert today.

Answer 2

Answer:

Many scholars believe that the collapse of the Indus Valley Civilization was caused by climate change. Some experts believe the drying of the Saraswati River, which began around 1900 BCE, was the main cause for climate change, while others conclude that a great flood struck the area.
