This above mentioned Monsoon failure theory is a doubtful correlation. This Monsoon decline theory is absolutely fine,there is no objection to that theory at all. But, only problem is that this monsoon decline theory is being correlated to the fall of Indus Valley Civilization,which is a kind of illogical correlation.
This theory is being slightly far-fetched. The Indus river is a perennial river and it doesn't dry up even in harsh summers because of the melting of glaciers. The river Indus supports nearly 18 crore people even today, can't it have supported a few thousand people 5000 years back? It looks like that there is some misinterpretation here.
There is a possibility that IVC never declined at all. These Indus Valley excavation sites are looking deserted because these sites were used as grave yards from time immemorial by various occupants of these lands.These sites have been wrongly identified as Metropolises, whereas in reality they were only Necropolises. This wrong identification is the reason for confusion surrounding theories like this about IVC. Follow the below given link for detailed information.
