Abstract
Land, landscape and soil have major implications on physical, economic, social and cultural development of a region. The three great ancient civilizations had also deep rooted in the earth with the prevailing and inherited milieu. The Harappan Civilization, once flourished in ancient time, lasted for hundreds of years covering present day India, Pakistan, Afghanistan, Iran and Iraq which have nourished by the more or less essence of physiographic environment. The manifold reasons of initiation, flourishment, expansion and ultimate destiny might have been preserved in the lithospheric cover of the Earth. The present study asserts and makes an endeavour to sort out mostly natural causes responsible for the growth and decline of the Harappan Civilization.
