Question

which factors led to the decline of indus valley civilization ​

Answer 1

Explanation:

HEY MATE ..

The theory of a huge climatic change or natural disaster gained credibility. It has been found out that around 2000 BC some major climatic changes started occurring in the Indus Valley.

These changes had led to floods in the plains and cities. Historians have found evidence to prove this theory as well. Most of the cities in the Harappan Civilization have been found in a condition as if these had been first abandoned and then rebuilt. Then, there was a fall in the average rainfall in the cities leading to the formation of desert-like condition. This led to the decline in agriculture on which most of the trade was dependent.

Owing to this, people of the Indus Valley started shifting to some other location leading to the decline in the entire civilization. As per some scholars, the reason of the decline is the change in the course of River Ghaggar-Harka that had led to an increase in aridity of the place. Around 2000 BC, there was found an increase in arid conditions. The location where the Indus valley civilisation once flourished is a desert today.
