Cauvery Water Dispute and CWMA Interstate Allocation Directives

આ શા માટે મહત્વનું છે

The Cauvery dispute is a classic case study for UPSC aspirants on the mechanisms (Article 262, Inter-State River Water Disputes Act) and challenges of inter-state resource sharing. It highlights the intersection of federalism, institutional arbitration (CWMA/CWRC), and the impact of climate variability on agriculture.

સારાંશ

The Cauvery Water Management Authority (CWMA) has upheld a directive requiring Karnataka to release 9,000 cusecs of water daily to Tamil Nadu for the next 15 days. Karnataka contested the decision, citing severe water distress due to poor rainfall, which left inflows into its reservoirs nearly 50% below the 30-year average. The state emphasized threats to its own drinking water and kharif irrigation needs while pointing out that Tamil Nadu would benefit from the upcoming Northeast Monsoon. In contrast, Tamil Nadu sought a larger share to cover a claimed backlog and support extensive ongoing Kuruvai cultivation. The recurring dispute highlights the limitations of existing mechanisms in managing inter-state water conflicts, especially amid climatic uncertainties and agricultural demands.

મુખ્ય મુદ્દા

  • The Cauvery Water Management Authority (CWMA) directed Karnataka to release water to Tamil Nadu at a rate of 9,000 cusecs per day for 15 days, totaling roughly 11.66 tmcft.
  • Karnataka requested the release be limited to 6,000 cusecs, citing a severe basin distress with a 49.18% deficit in cumulative inflows to its four reservoirs compared to the 30-year average.
  • Karnataka argued it had already released 18.748 tmcft against the mandated 15.940 tmcft in the preceding period, and highlighted its unmet kharif irrigation requirement of 111.52 tmcft.
  • Tamil Nadu demanded 28.386 tmcft to cover an alleged backlog of 17.49 tmcft and sustain extensive Kuruvai cultivation over 8.41 lakh acres.
  • The conflict underscores the vulnerabilities of rain-fed agriculture and the complexities of inter-state resource sharing under federal structures during rainfall-deficient years.

"The Supreme Court is strictly barred from exercising any jurisdiction over inter-state river water disputes."

While Article 262 allows Parliament to bar SC jurisdiction, the SC still exercises appellate jurisdiction under Article 136 (Special Leave Petition) to hear appeals against tribunal awards.

Polity & Governance

What is the Constitutional framework governing Inter-State River Water Disputes?

  • Article 262: Empowers Parliament to provide for the adjudication of inter-state river/river valley disputes and allows it to bar Supreme Court jurisdiction.
  • ISRWD Act, 1956: Enacted under Article 262, it provides the legal machinery to set up ad-hoc tribunals for dispute resolution. CWMA was created under this Act.
  • River Boards Act: Allows the Union to establish advisory boards for the regulation and development of inter-state rivers and river valleys.
Indian Geography & Agriculture

What are the key rice cropping seasons in the Cauvery delta?

  • Kuruvai: A short-duration paddy crop in Tamil Nadu grown during June-July. It heavily relies on timely water release from Karnataka during the Southwest monsoon.
  • Samba: A long-duration paddy crop sown between August and January. It primarily depends on the Northeast Monsoon and subsequent river flows.
  • Thaladi / Navarai: Late-sown short-duration crop (December to March) cultivated using available reservoir water during the dry season.

આંતર-વિષય પેટર્ન

  • Climate Change meets Cooperative Federalism

    Erratic Southwest and Northeast monsoons due to climate change directly amplify inter-state resource conflicts, turning a climatic vulnerability into a core challenge for cooperative federalism.

  • Water Tribunals vs Inter-State Council

    Aspirants should contrast the ad-hoc nature of water dispute tribunals under Article 262 with the constitutional mandate of the Inter-State Council (Article 263) for resolving broader federal frictions.

Expect a multi-statement question combining Article 262, the statutory status of CWMA, and TN/Karnataka's overlapping cropping seasons.
