Tamil Nadu-Karnataka Cauvery Water Dispute: Assembly Resolution Highlights Systemic Failure in Transboundary Water Governance and Climate Adaptation

The Cauvery dispute dates back to 1892, when the British colonial government formalised water allocation between the Madras Presidency and Mysore State, embedding colonial-era inequities into modern governance. The 1924 agreement, extended post-independence, failed to account for demographic and ecological changes, setting the stage for recurring conflicts. The 2018 Supreme Court verdict, which upheld Karnataka’s share while acknowledging Tamil Nadu’s rights, exposed the inadequacy of adjudicatory mechanisms in addressing basin-wide challenges.
The Tamil Nadu Assembly’s resolution against Karnataka’s Mekedatu dam plan is not merely a bilateral dispute but a symptom of India’s broader failure to govern water as a shared, living entity.
The colonial legacy of adversarial water governance, compounded by climate change and elite capture, has reduced the Cauvery to a zero-sum resource, pitting states against each other while marginalising those who depend on it most. Indigenous systems like *aeri* tanks and *vayalagam* wetlands, which once sustained basin resilience, offer a blueprint for decentralised, equitable management—but their erasure from policy discourse reflects a deeper epistemic violence. The path forward requires a paradigm shift: from state-centric adjudication to basin-wide cooperation, from dams as symbols of progress to rivers as sovereign entities, and from political brinkmanship to participatory, climate-resilient governance. Without this, the Cauvery’s future—and the millions who depend on it—will be dictated by scarcity, conflict, and the absurd theatre of electoral politics.
