Aridity lead to collapse of IVC

                     A new study,of variations in the Indian monsoon over 10,000 years, by researchers at the Woods Hole Oceanographic Institution (WHOI) is shedding new light on the end of the Harappan civilisation. According to a WHOI release: ‘The geological record and archaeological evidence tell a story of the possible fate of India’s earliest civilisations. Cultural changes occurred across the Indian Subcontinent as the climate became more arid after about 4,000 years. In the already dry Indus basin, the urban Harappan civilisation failed to adapt to even harsher conditions and slowly collapsed. But aridity favoured an increase in sophistication in central and south India where tropical forest decreased in extent and people began to settle and [undertake] more agriculture. Human resourcefulness proved again crucial in the rapid proliferation of rain-collecting water tanks across the Indian peninsula, just as the long series of droughts settled in over the last 1,700 years.’
