The chairperson has proposed creating a river board for the entire Cauvery basin to resolve the ongoing water-sharing dispute between Tamil Nadu and Karnataka. This proposal highlights the concept of managing rivers as single hydrological units rather than dividing them by political boundaries, drawing attention to the underutilized .
Water is a State subject (Entry 17 of State List), but the Union can regulate and develop inter-state rivers under Entry 56 of Union List if Parliament declares it expedient in the public interest. To manage inter-state rivers, Parliament enacted two key laws under Article 262: the Inter-State Water Disputes Act, 1956 (for adjudication) and the River Boards Act, 1956 (for advisory river boards). Despite the legislative framework, not a single river board has been created under the River Boards Act, 1956. This failure stems from the reluctance of States to cede control over water resources and the Centre's hesitancy to intervene, citing water as a State subject. Existing bodies like the Damodar Valley Corporation and the Cauvery Water Management Authority were established through specific statutes, executive orders, or tribunal awards, bypassing the 1956 Act. The Punchhi Commission on Centre-State relations recommended linking the establishment of inter-state river boards with tribunals, emphasizing an integrated watershed approach to resolve disputes before they escalate.
The core geographical principle in water management is the river basin approach, treating a river and its tributaries as a single, interconnected hydrological unit from source to sink. This contrasts sharply with the current administrative approach, where political boundaries disrupt the natural flow and management of the river. Effective management, as seen in international examples like Australia's Murray-Darling Basin Authority, requires understanding complex connections among climate, river flows, ecosystems, and human utilization. In India, disputes arise because upper riparian states (like Karnataka in the Cauvery basin) control the flow to lower riparian states (like Tamil Nadu). A river board operating across political boundaries could optimize water storage, manage floods and droughts more effectively, and ensure a minimum ecological flow, balancing the needs of all basin states.
The chronic failure of intra-state river boards, such as those attempted in Tamil Nadu and Kerala, highlights a deeper governance deficit in water management. Even when established, these boards often become defunct due to lack of political will, inadequate funding, and limited statutory power to enforce decisions. To revitalize the river board concept, the Centre must offer substantial financial incentives, perhaps through conditional grants linked to cooperative basin management. The proposed but stalled amendments to the Inter-State River Water Disputes Act, aimed at creating a permanent single tribunal with strict timelines, suggest a shift towards more streamlined adjudication, but this must be paired with proactive, cooperative management through river boards. Promoting dialogue through platforms like Zonal Councils could foster the political consensus necessary for effective basin-wide governance.
