The downfall of the Indus Valley Civilisation

Climate change could be associated with the downfall of the Indus Valley Civilisation. The climate grew cooler and drier from about 1800 BCE, which could be linked to a general weakening of the monsoon at that time. Another crucial factor may have been the disappearance of many portions of the river system. However, like any other decline of a civilisation, will have been due to a combination of various reasons such as it might have been to dry or that the river was running out of fish. Some researchers are trying to find out how the rivers in that region has changed since 8000 years ago.
