Water, one of the most valuable free gift of nature and part and parcel of life saving gas oxygen, is the life and blood of all creatures of earth without which none can survive. Water, as referred in Vedas and other socio-economic documents, consists of ecological, biological, geological, social, physical, religious, political and cultural values. Today, water scarcity has emerged as global problem consequently, more informed approach is being recognised and articulated all over the globe.India has been facing acute water crises despite its adequacy with growing needs on account of rapid population growth, economic development, pollution and climatic changes. She has been the victim of recurring floods and droughts in maximum part of its geographical areas.
• As per surveys efficiency in water use was mere 40 per cent in India, while it was around 60 per cent in many other countries. so, now inter-linking of rivers is the only major solution.

Thus, for the permanent solution of severe and recurring droughts and floods and scarcity of drinking water the connectivity of Indian rivers has been suggested as quite essential. Keeping in view the various issues like environmental, social, economic, political and inter-state conflicts, International conflicts of rivers water sharing etc., the interlinking of rivers in India is the only solution.The idea behind river interlinking is based on the fact that an enormous amount of water from rivers flows into the sea. It is envisaged that if this is prevented and water is transferred from water surplus rivers deficit, there will be adequate supply of water for everyone in every part of the country. Former President A P J Abdul Kalam opined the same that there was a greater need for inter-linking of rivers in the country to tackle the water crisis. Rivers like Cauvery, Krishna, Tungabhadra and others needed to be inter-linked to solve the severe problem of water crisis. If we can, regional imbalances could be reduced significantly and lot of benefits by way of additional irrigation, domestic and industrial water supply, hydropower generation, navigational facilities etc. would accrue.
