Cauvery Dispute — Ek Nadi, Do Rajya, aur Constitution ka Puzzle

Ek nadi, do rajya, aur Constitution ka puzzle. Article 262 ne river disputes ko courts se bahar rakha, phir Supreme Court appellate darwaze se andar aa gaya. Prelims foundation — Tribunal, CWMA/CWRC, tributaries, reservoirs, delta, Mekedatu, monsoon — aur uske upar chaar Mains themes jo Cauvery se organically nikalte hain: state-vs-state tension, federalism ke teen moods, environment ka federal reshape, aur regionalism ka resource-based naya avatar.

Federalism & centre-state relations Separation of powers & dispute redressal Communalism, regionalism & secularism Indian monsoon & climate systems Distribution of key natural resources Conservation Cropping patterns & irrigation

Foundation and Concepts (Prelims Layer)

Aaj Kya Cover Karenge — Pehle Roadmap

Ek nadi, do rajya, aur Constitution ka puzzle — Prelims foundation se lekar Mains analytical framework tak, ek jagah.

Part 1 — Foundation aur Concepts (Prelims layer). Cauvery dispute ki puri kahani story mode mein — Constitution, Tribunal, Supreme Court, CWMA/CWRC, geography, reservoirs, delta, Mekedatu, monsoon aur distress-sharing.

Part 2 — Mains analytical layer. Chaar themes jo Cauvery se organic taur pe nikalte hain — state tension, federalism ke teen roop, environment ka federal reshape, aur regionalism ka naya avatar. Har theme ke saath analytical insights.

Part 3 — Model questions with framework aur answers. Teen model questions PYQ pattern pe based, framework + 250-word model answer + extra dimensions + highlight lines.

Scene 1: Chai ki tapri pe sawaal

Socho — ek chai ki tapri pe do dost baithe hain. Ek Bengaluru se, ek Thanjavur se. Dono ek hi nadi ka paani peete hain — Cauvery. Lekin dono ladte rehte hain. Bengaluru wala kehta hai "bhai, pehle mera ghar, mera khet." Thanjavur wala kehta hai "arre, nadi toh neeche behti hai, mera hissa mat rok."

Yeh sirf do doston ki kahani nahi hai. Yeh Karnataka aur Tamil Nadu ki 150 saal purani ladai hai. Aur is ladai ko samajhne ke liye humein bahut peeche jaana padega — jab desh bana bhi nahi tha, jab angrez the, jab Constitution likha ja raha tha.

Scene 2: Constitution wale kya soch rahe the?

1947 mein desh azaad hua. 1950 mein Constitution laagu hua. Ambedkar sahab aur baaki framers ke saamne ek badi problem thi — rivers toh states ke beech se behti hain. Ganga UP se Bihar jaati hai. Krishna Maharashtra se Andhra jaati hai. Cauvery Karnataka se Tamil Nadu jaati hai.

Ab agar do states ladenge paani pe, toh kaun solve karega?

Framers ne socha — "Supreme Court ko dete hain? Nahi yaar, judges technical paani ka calculation kaise karenge? Kitna cusec chahiye, kitna reservoir mein hai, monsoon kaisa hai — yeh sab toh engineers ka kaam hai."

Toh unhone Constitution mein daala Article 262. Isme do baatein likhi:

Clause 1: Parliament kaanoon bana sakti hai inter-state river disputes solve karne ke liye.
Clause 2: Parliament chahe toh Supreme Court ko bhi bar kar sakti hai in disputes se.

Yeh unusual tha. Normally SC toh sab kuch dekhta hai. Lekin river water pe framers ne socha — "isko technical experts ke haath mein rakho, courts ke haath mein nahi."

Scene 3: Parliament ne kya kiya?

1956 mein — jab states linguistic basis pe reorganize ho rahe the — Parliament do kaanoon lekar aayi:

Inter-State River Water Disputes Act, 1956 — Jab bhi do ya zyada states ke beech river water pe jhagda ho, Centre ek Tribunal banayega. Yeh Tribunal Supreme Court ya High Court ke sitting judges ka hota hai, jinhe Chief Justice of India nominate karte hain. Award challenge nahi kar sakte normal courts mein — Article 262(2) ka bar hai.

River Boards Act, 1956 — Har river ke liye ek Board banayenge jo planning, development, sab coordinate karega.

Dukhad baat — River Boards Act 1956 mein hai, lekin aaj tak ek bhi River Board actually constitute nahi hua. States ne cooperate hi nahi kiya. Dispute prevention ka mechanism fail ho gaya, aur sirf dispute resolution wala Tribunal chalta raha.

Prelims favourite: "Which of the following River Boards has been constituted under the River Boards Act, 1956?" Answer: none. The Act is on the statute book and has never once been used.

Yaad rakhne ka tareeka — 1956 mein do Acts bane. Ek chal gaya (ISRWD, disputes ke liye), doosra kabhi start hi nahi hua (River Boards, prevention ke liye). India ke paas jhagda solve karne ka mechanism hai, jhagda rokne ka nahi.

Scene 4: Cauvery ka jhagda — jad kahan hai?

1892 aur 1924 mein jaana padega. Uss zamane mein Karnataka nahi tha, Tamil Nadu nahi tha. Tha Mysore Princely State aur Madras Presidency. Dono ke beech Cauvery ka paani baantne ke 1892 aur 1924 mein agreements hue. In agreements ne Madras (downstream) ko zyada hissa diya, kyunki delta ki kheti purani thi.

1947 ke baad Mysore ban gaya Karnataka. Madras ban gaya Tamil Nadu. Karnataka ne kehna shuru kiya — "yeh agreements toh angrezon ke zamane ke the, humein force nahi kiya ja sakta. Humari upstream position hai, humein zyada paani milna chahiye."

Tamil Nadu bola — "agreements toh agreements hain, aur hum 150 saal se delta mein chawal uga rahe hain, humara historical use hai."

Tamil Nadu 1986 mein Centre ke paas gaya — "Tribunal banao."

Scene 5: Cauvery Water Disputes Tribunal ki entry

1990 mein CWDT bana (Cauvery Water Disputes Tribunal). Chairman the Justice Chittatosh Mookerjee. Scope — Karnataka, Tamil Nadu, Kerala, aur Puducherry (Puducherry party hai kyunki Karaikal region Cauvery delta mein hai).

Tribunal ne 17 saal lagaye — 1990 mein constitute hua, 2007 mein final award diya. Beech mein interim orders diye. Riots hue Bengaluru mein 1991 mein jab interim order aaya.

Final award 2007 mein — Total available water 740 tmc ft baanta gaya:

Tamil Nadu — 419 tmc ft (sabse zyada, delta agriculture)
Karnataka — 270 tmc ft
Kerala — 30 tmc ft
Puducherry — 7 tmc ft
Environmental purposes aur sea escape ke liye baaki

Schedule diya — June se May tak, har mahine Karnataka ko Tamil Nadu ko Billigundulu point pe kitna paani chhodna hai. Billigundulu Karnataka-Tamil Nadu border pe measuring station hai.
