Rivers, Dams & Water DisputesTemples of Modern India, Re-examined

Nehru called dams the 'temples of modern India'. In Bihar, the Kosi, Gandak and Son projects brought irrigation, power and flood control; elsewhere, big dams displaced people and divided states. This page weighs the benefits and costs of river projects and asks how water disputes can be solved.

Multipurpose river projects

Multipurpose river projects refers to the building of large dams where the many uses of the impounded water are integrated with one another. e.g. for generating hydro-electricity and for supplying water for irrigation, industrial and domestic purposes.

Multi-purpose projects, launched after Independence with their integrated water resources management approach, were thought of as the vehicle that would lead the nation to development and progress, overcoming the handicap of its colonial past. Jawaharlal Nehru proudly proclaimed the dams as the 'temples of modern India'; the reason being that it would integrate development of agriculture and the village economy with rapid industrialisation and growth of the urban economy.

Shared rivers, shared quarrels

India has about twenty major river basins running through the nation and many of these traverse more than one state. This leads to conflicts regarding the use and distribution of water.

Some of the major River Water Disputes in India are Cauvery Water Dispute (between Karnataka and Tamil Nadu), Mahanadi water dispute (between Odisha and Chhattisgarh), Mahadayi river disputes between Goa, Karnataka and Maharashtra, Krishna river dispute between Maharashtra, Karnataka and AP etc.

Example: One dam, many uses: the same reservoir stores monsoon floodwater (flood control), releases it through canals in the dry season (irrigation), drops it through turbines (hydro-power) and supplies towns (drinking water).

“The decision should be based on adequate cost and benefits analysis not only in economic terms but also in social and environmental terms.”
