ECOLOGICAL CHANGES IN ANCIENT INDIARakesh
A few studies available have focused on climate change, migration and topographical change in ancient India, however, topographical changes, history and migration is fully interconnected to each other.Many studies based on literary and archaeology suggested that Aryans migrated to the Ganga Yamunadoab from the northwest, but scholars do not inform what route they followed and what topographicalchanged were brought by Aryans during the earlier migration? Aryan followed the course of the Yamunaand Ganga because this route was less dense forest. While, north region was surrounded by hilly regionand cold, while, south region (modern Rajasthan) was dry zone area, as well as, most of the area was notsuitable for agriculture. The studies (Basham, 1967; Romila Thapar, 2002) explained how Aryan settled inthe Ganga plain but these did not throw light over the Aryanâs migration in the humid zone. However,archaeological evidences suggested that people were already moving from the west to east; even fromsouth to north. But archaeologist failed to explain pattern of migration during 1000-1500 BCE. It seems thatenvironmental conditions were much favourable in the Ganga valley; as well as, the area was suitable forthe mixed economy.
