UPSC / SSC current affairs note · Polity
Why in news
The latest 2026 directive from the Cauvery Water Management Authority (CWMA) has again triggered protests in Karnataka, continuing a pattern seen since 1991. This recurring issue highlights the persistent inter-state water dispute and its political sensitivity.
Background
The Cauvery water dispute involves the states of Karnataka, Tamil Nadu, Kerala, and Puducherry. It dates back to colonial-era agreements and has been adjudicated by tribunals and the Supreme Court. The 1991 tribunal award and subsequent orders have been contentious, especially in Karnataka, which often faces water scarcity.
Key facts
Every major order directing Karnataka to release Cauvery water has sparked protests, political mobilisation, and legal battles.
The 1991 Cauvery Water Disputes Tribunal (CWDT) award was the first major order.
The Supreme Court issued rulings in 2016 and 2018 modifying the tribunal award.
The Cauvery Water Management Authority (CWMA) was constituted in 2018 to implement the final award.
The latest directive is from 2026, issued by the CWMA.
Protests have been a recurring feature in Karnataka in response to these orders.
The dispute involves multiple states: Karnataka, Tamil Nadu, Kerala, and Puducherry.
The issue is a classic example of inter-state river water sharing conflicts in India.
