A dry spell along the Cauvery
A weak monsoon has left farmers on both sides of the Cauvery struggling with dwindling water supplies. In Karnataka, farmers are worried about irrigation even as the State faces pressure to release water to Tamil Nadu, where large tracts of paddy fields remain barren. The competing demands have sharpened tensions between the two States

Context
Farmers in the Cauvery basin, specifically at the tail end of the Visvesvaraya irrigation canal system drawing from the Krishna Raja Sagara (KRS) reservoir, are facing severe water shortages, threatening their paddy crops. The delay in water release highlights the recurring vulnerability of agriculture in the region to monsoon variations and the ongoing complexities of inter-state river water sharing.
UPSC Perspectives
Geographical
The Cauvery River originates in , Kodagu district, Karnataka, and flows through Karnataka, Tamil Nadu, Kerala, and Puducherry. The article mentions the Krishna Raja Sagara (KRS) reservoir, a crucial infrastructure built across the Cauvery near Mysuru. The situation illustrates the geographical challenge of water distribution within an irrigation network; farmers at the "tail end" of the Visvesvaraya irrigation canal are the most vulnerable as water pressure drops and supply is often exhausted by upstream users before reaching them. This geographical reality exacerbates the impact of delayed monsoons or deficit rainfall. UPSC often tests knowledge of river systems, their tributaries (like Hemavati, Kabini, Bhavani for Cauvery), and major dams/reservoirs on these rivers.
Polity
The dry spell in the Cauvery basin inevitably re-ignites the inter-state river water dispute between Karnataka and Tamil Nadu. The Constitution addresses this under , which empowers Parliament to adjudicate disputes related to inter-state rivers and river valleys. Parliament enacted the under this provision. The long-standing Cauvery dispute led to the formation of the , whose final award was modified by the Supreme Court in 2018. To implement this award, the central government established the and the Cauvery Water Regulation Committee (CWRC). When rainfall is deficit, these bodies face the complex task of enforcing distress-sharing formulas, often leading to political friction between the riparian states, a classic challenge of cooperative federalism.
Economic
The plight of the farmer underscores the deep economic vulnerability of Indian agriculture, which remains heavily dependent on the Southwest Monsoon. The cultivation of water-intensive crops like paddy in areas prone to water scarcity creates severe economic risks. The farmer's potential loss of ₹8,000 spent on raising the nursery highlights the sunk costs and the lack of a reliable safety net for marginal farmers facing climatic uncertainties. This situation emphasizes the urgent need for a shift towards climate-resilient agriculture, promoting less water-intensive crops (like millets under the ), and improving water use efficiency through micro-irrigation schemes (like ). The recurring water crisis in the Cauvery basin affects agricultural productivity, farm incomes, and ultimately, regional economic stability.
