Context
The Chairperson of the has proposed the creation of a comprehensive river board to manage the entire Cauvery basin, aiming to resolve ongoing water disputes between Tamil Nadu and Karnataka. The proposal suggests a model similar to the , which would own, operate, manage, and regulate reservoirs, moving beyond the current regulatory framework to a more integrated, basin-wide management approach.
UPSC Perspectives
Polity
The dispute highlights the complexities of cooperative federalism and inter-state water dispute resolution in India. Under the Constitution, water is a State subject (Entry 17, State List), but the Union has jurisdiction over inter-state rivers (Entry 56, Union List) if Parliament declares it expedient in the public interest. The provides the legal framework for resolving these conflicts, leading to the formation of tribunals like the . The , established in 2018, is a regulatory body ensuring the implementation of the CWDT's award. The proposal to create a basin authority modelled on the represents a shift from a purely regulatory approach to an operational one, where a central body manages the physical infrastructure, requiring significant political consensus between the riparian states. The article also notes the role of the , which acts as the final arbiter when states refuse to comply with the CWMA's directives.
Governance
The proposal advocates for integrated river basin management (IRBM), a paradigm shift from state-centric management to a holistic, basin-wide approach. Currently, states manage their respective infrastructure, often leading to uncoordinated releases and conflicts during distress years (low rainfall). A comprehensive institution like the proposed river board, or existing models like the and the , synchronizes operations across states. This includes coordinating irrigation releases with power generation and ensuring equitable distribution based on real-time data rather than rigid quotas. The CWMA chief's emphasis on prioritizing drinking water and environmental flows over irrigation during distress years reflects a governance model focused on sustainability and essential needs, challenging the politically sensitive demand for agricultural water in deficit years.
Geography
The Cauvery basin's geography makes it highly susceptible to variations in the Southwest Monsoon. The river's yield, assessed at 740 TMC ft at 50% dependability, implies that in half of a 10-year cycle, water availability will be less than optimal. This inherent hydrological variability is the root cause of the dispute. During distress years, when the monsoon fails to deliver the expected rainfall in the catchment areas (primarily in Karnataka), the upper riparian state struggles to release the mandated quantum of water to the lower riparian state (Tamil Nadu), which relies heavily on the northeast monsoon and the Cauvery for its extensive delta irrigation. The article underscores the necessity of demand management in agriculture, suggesting that cropping patterns must adapt to the hydrological realities of the basin, rather than relying on an assumption of normal rainfall every year.
