Discuss the causes and consequences of inter-State water disputes in India. (2026, 20 Marks)
Almost every major Indian river crosses state lines, so a single hydrological unit is shared among politically autonomous claimants. Alan Richards and Nirvikar Singh argue that such disputes persist because they are absorbed into general centre–state bargaining rather than settled by neutral institutions. Their causes are physical, legal and political; their consequences reach far beyond water.
Causes
- Scarcity and variability: per-capita availability was assessed at about 1,486 cubic metres in 2021, inside the “stress” band, and the Pennar, Sabarmati and several east-flowing basins are already below the scarcity line. Monsoon failure turns allocation into a zero-sum contest, as in the Cauvery distress year of 2023.
- Rising demand: agriculture takes roughly four-fifths of withdrawals, and urban drinking water (Bengaluru; Hubballi–Dharwad via the Mahadayi diversion) and industry (Chhattisgarh’s barrages upstream of Hirakud) now compete with it.
- Clashing doctrines: upper riparians claim territorial sovereignty and lower riparians historic use; Punjab denies that a non-basin state like Haryana has any claim. Tribunals apply equitable apportionment without an agreed weighting of factors.
- Colonial and reorganisation legacies: the Cauvery agreements of 1892 and 1924 and the 1886 Mullaperiyar lease; Punjab’s 1966 division and Andhra Pradesh’s 2014 bifurcation, which left Krishna entitlements undivided.
- Union abdication: Parliament has never used Entry 56 for a general river law, and no board has ever been set up under the River Boards Act 1956. States also build projects early to strengthen their bargaining positions.
- Electoral incentives: since regional parties came to power in the disputing states, chief ministers gain more from being seen to fight than from settling.
Consequences
- Political: water becomes an identity issue. Karnataka’s bandh of 29 September 2023, Tamil Nadu’s rail blockades and the SYL canal in every Punjab election show its mobilising power.
- Federal: states defy or legislate against settlements — Karnataka’s 1991 ordinance and Punjab’s Termination of Agreements Act 2004, both held unconstitutional. In May 2025 Punjab resisted the Bhakra Beas Management Board‘s release of extra water to Haryana until the High Court restrained it (6 May 2025). Horizontal conflict also invites vertical centralisation, as the Union and the courts step in.
- Economic: the SYL canal is unfinished four decades on; Mekedatu and the Mahadayi diversion are stalled; farmers face seasonal uncertainty and projects cost overruns.
- Ecological: allocation fights crowd out environmental flows, delta health and groundwater.
- Legal: despite Article 262, disputes return to the Supreme Court through Articles 136 and 131. Cauvery took from a 1970 request to a 2018 judgment; the 1987 Ravi–Beas report is still unnotified; Krishna-II has sat for two decades; and in the Pennaiyar dispute the Court itself ordered a tribunal on 2 February 2026.
The picture is not wholly bleak. The largely consent-based Godavari award (1979) has generated little litigation, and since 2018 the Cauvery Authority has turned open conflict into annual administered bargaining: the disputes persist, but they rarely escalate.
Way forward
- Revive the lapsed ISRWD (Amendment) Bill 2019: a permanent tribunal, mediation first, a national data bank, and self-executing awards.
- Create basin organisations and a National Water Commission (Mihir Shah Committee, 2016), with distress-sharing formulas.
- Use negotiation forums: the SYL chief ministers’ meeting (27 January 2026) and the 31st Southern Zonal Council (August 2026) show dialogue moving what litigation could not.
Conclusion
Scarcity sets the stage, but politics sustains these disputes: an absent Union, electorally rewarded intransigence and unenforced awards. Their costs — political mobilisation, federal distrust, stalled investment and ecological neglect — can be contained only by basin-level, data-driven cooperative federalism.
