- Why in news
- On 10 August 2026 the Jal Shakti Ministry told Rajya Sabha the status of the 30 river-linking projects under the National Perspective Plan. Only the Ken-Betwa link has entered implementation as a priority link.
- What it is
- The National Perspective Plan (NPP) is the Government of India's plan for inter-basin water transfer, moving water from surplus to deficit river basins. It has a Peninsular and a Himalayan component. The National Water Development Agency (NWDA) studies and prepares reports for the links.
- Number of links
- 30 links were identified under the NPP: 16 Peninsular and 14 Himalayan.
- Implementing agency
- NWDA has been given the work of river interlinking.
- Environmental safeguards
- An EIA is part of every FR and DPR. Ken-Betwa has an Integrated Landscape Management Plan.
- Kosi-Mechi
- The inter-state Kosi-Mechi link was dropped because of international dimensions. NWDA studied an intra-state version for Bihar.
Don’t confuse with Ken-Betwa vs Polavaram: Ken-Betwa is a priority NPP link implemented as a central project. Polavaram is a National Project executed by Andhra Pradesh and the Polavaram Project Authority.
Don’t confuse with Peninsular vs Himalayan component: The Peninsular component has 16 links and the Himalayan has 14. Himalayan links involve Nepal and Bhutan-side rivers in some cases.
Schemes: 52 Prelims questions since 2013, 10 in Prelims 2026 alone. They test features, the period and who funds it. In Mains, 33 news-triggered questions, mostly GS3.
Why it matters
- Moves water from surplus to deficit basins, helping drought-prone regions.
- Adds irrigation, drinking water and hydropower, as Ken-Betwa shows.
Problems
- Only one priority link has reached implementation; many links remain at report stage.
- Consensus on dams and water sharing between states is pending, and some Himalayan links have international dimensions.
- Environmental, forest and R&R concerns need strict compliance.
Way forward
- Build state consensus through the NWDA and the Centre before preparing project reports.
- Use EIAs and landscape management plans, with long-term monitoring, for every link.
Put in your answer
Ken-Betwa data: About 11.88 lakh hectares irrigation, 62 lakh people drinking water, 103 MW hydropower and 27 MW solar at ₹44,605 crore.
Netravati-Hemavati example: Further studies stopped because the Yettinahole project left no surplus water in the Netravati basin.

Mains practice
15 marks · 250 words
The Jal Shakti Ministry has told Parliament that, of the 30 links identified under the National Perspective Plan, only the Ken-Betwa link has entered implementation as a priority link. In this context, critically examine the rationale of inter-basin water transfer in India and discuss the economic, environmental, social and inter-state challenges that slow the National River Linking Project.
Worth revising until Prelims 2028: most news questions come within two years of the event.
