The rain fall was low in harappan region
Answers
The Indus Valley, or Harappan, civilisation was an expansive human settlement along the banks of the Indus and Ghaggar-Hakra rivers from around 3,500 BCE, occupying large parts of what are Gujarat, the Indus valley and northwest India today. The civilisation’s many advancements, especially in urban planning and engineering, have had it occupying the pride of place in India’s history as a sign of our own advanced knowledge systems.
Around 1,300 BCE, the civilisation petered out for reasons that aren’t entirely known. A change in monsoon patterns has been the prime suspect. However, the lack of continuous climate records from the time has prevented scientists from confirming this suspicion, leaving the civilisation’s dissipation a matter of debate.
