Irrigation in India helps improve food security, reduce dependence on monsoons, improve agricultural productivity and create rural job opportunities. India’s total area under irrigation is 64.7 million hectares. Of this maximum 45% is shared by tube wells followed by Canals and wells. So, in India wells and tubewells has the maximum area.
