Karnataka has equal rights on Cauvery as more than half the water in the river is due to karnataka. Just because irrigation was more developed in TN regions( mainly due to British arm twisting the Mysore rulers as per available documents presented in front of cauvery tribunal), it doesn't mean that they should continue to enjoy it in perpetuity. Let them shift to different crops.
More than half part is debatable.. I dont know what the settled law is in such a cases.. more sensible would be historical flows at different stretches (upstream and downstream of tributaries) and the length in each state..
As for Thanjavur, well.. It has been an irrigated region for more than 600 years or so.. Kallanai (Stone dam) was built by Karikal Cholan.. So that is not new. Mettur Dam /Stanley came up in 1934 or so.. KRS came up in 1920s I think (not sure).. or maybe before that even , given Sir Vishweshwariah's contributions to it (one of the greatest sons of Karnataka in my opinion). I doubt anyone could argue given that KRS came up
before Mettur, that TN armtwisted Karanataka in building irrigation.. Anyways, I am not the expert here, could well be wrong.
Why should they insist on growing three crops of paddy per year irrespective of the amount of water in the river?
Now you are talking rational sensible stuff. To add to your question , why use methods unchanged for 5000 years (flooding of paddy fields).. why not other more water saving methods, why not change crop patters.. all very pertinent. the question is not just for TN , but for Karnataka as well.Karnataka was to increase acerage of sugarcane and paddy!..
Same problem in Western Maharasthra as well with it's sugar lobby (sharad pawar) and huge use of water.
However, all that requires political will, ability to take on lobbies and vested interests and fight for overall good. That is close to impossible to do in a political system like ours...
Actually Kallanai is older than I thougth..
Check out Kallanai or Grand Anicut ..
This was one of the reasons the Chola kingdoms were the super power /regional hegemon of those days and spread infleunce and wielded power all the way upto Cambodia/Indonesia / Burma/Sri Lanka etc.., not to talk of neighboring states in India.
