Hi, I do accept water is essential for all civilisations to sustain. What I am trying to emphasise is close to 60% of kaveri catchment areas are in TN. Will TN pls build reservoirs and dams to harness rain water in these areas. It will not only provide more water (becos of two monsoons) but also additional hydro-electric power. The only reason to impediment TN govt is submergence of some land - this will be politically suicidal. But in the long term, the state as well as the Union will benefit.
I therefore even provided the example of a colony doing water-harvesting. By what TN is claiming it will be a blow to states who invest in water management projects. Also experts in irrigation point to the current water shortage crisis as being driven by reckless sugarcane ( a know water-guzzling crop) cultivation in the upper TN tracts. I am not opposed to Karnataka giving waters when there is excess, but when there is a drought, it gets first share as it had the foresight to invest in the water mgmt system.
