The Harappa civilization was not built in a day and it was not destroyed in one day or for one reason. Scholars have come forth with several conjectures to explain the decline of Harappan Civilization.
- Due to change in the climatic condition, the area lost fertility and people were compelled to move else where.
- Constant use of firewood for brick manufacture caused deforestation and minimized the rainfall.
- The change of course of the river Indus transformed it into a tract of sand and affected the fertility.
- Natural calamities could have adversely affected the normal life.
- Some scholars are of opinion that the Harappan civilization suffered a decline due to attacks by the hostile tribes.
