Not many years ago, river linking was a concept but it is becoming a reality in the country. Discuss the advantages of river linking and its possible impact on the environment.
Approach · directive: “discuss”
What it asks · Discuss the benefits of interlinking rivers and the environmental risks that come with moving water between basins.
It asks 2 things — answer each
- Discuss the advantages of river linking
- Discuss its possible impact on the environment
Open with · Historical opening: the National Perspective Plan (1980) identified 30 links, 14 Himalayan and 16 peninsular, to move water from surplus to deficit basins; in December 2021 the Cabinet approved the first, Ken-Betwa, at Rs 44,605 crore.
Cover
- Irrigation and drought relief: Ken-Betwa alone promises 10.62 lakh hectares in drought-prone Bundelkhand, from Panna to Jhansi.
- Flood moderation: storages and diversions on the Ganga-Brahmaputra system can reduce floods in Bihar, Assam and eastern Uttar Pradesh.
- Other gains: drinking water for 62 lakh people and 103 MW hydropower in Ken-Betwa; navigation, groundwater recharge and industrial supply elsewhere.
- Ecological cost: dams and canals submerge forests and displace people; the Ken-Betwa reservoir lies in the Panna tiger landscape.
- River health: changed flows, less silt and freshwater to deltas and estuaries, salinity ingress and effects on fish and wetlands.
- Other concerns: contested 'surplus', climate change altering flows, huge cost, inter-State disputes and downstream neighbours Bangladesh and Nepal.
- Way forward: independent appraisal of each link, the Mihir Shah Committee's (2016) National Water Framework law, and cheaper options first: watershed development, rainwater harvesting, micro-irrigation and demand management.
Close with · River linking should be the last resort after a basin's own water is saved; appraised link by link, it can serve SDG 6 (water for all) without sacrificing the rivers themselves.

The National Perspective Plan (1980) identified 30 links, 14 Himalayan and 16 peninsular, to move water from surplus to deficit basins; in December 2021 the Cabinet approved the first, Ken-Betwa, at Rs 44,605 crore.
Advantages of river linking
- Irrigation and drought relief: Ken-Betwa promises 10.62 lakh hectares in drought-prone Bundelkhand, from Panna to Jhansi.
- Flood moderation: storages on the Ganga-Brahmaputra system can temper floods in Bihar, Assam and eastern UP.
- Multiple uses: drinking water for 62 lakh people and 103 MW hydropower in Ken-Betwa; navigation elsewhere.
Possible impact on the environment
| Aspect | Promise | Risk |
|---|---|---|
| Water | 10.62 lakh ha irrigated | 'surplus' basins uncertain |
| Forests | 103 MW hydropower | Panna tiger habitat submerged |
- Submergence: dams drown forests and villages; Ken-Betwa's reservoir lies in the Panna tiger landscape.
- River health: altered flows, less silt and freshwater to deltas, salinity ingress, blocked fish migration.
- Contested science: 'surplus' is debatable and climate change shifts rainfall and glacier melt; inter-State disputes and downstream Bangladesh and Nepal add friction.
Way forward
- Appraise each link: independent environmental and social assessment first, within the National Water Framework law the Mihir Shah Committee (2016) proposed.
- Cheaper first: watershed development, rainwater harvesting, micro-irrigation and demand management.
River linking should be the last resort after a basin's own water is saved; appraised link by link, it can serve SDG 6 (water for all) without sacrificing the rivers.
