feels like u have done good survey. it was very interesting to learn these facts. But for building dams u need more land, u might have to evacuate people and and lose irrigational land. And when it comes to leaving river water into sea, if that is not done proportionately, the salt of the sea will increase and affect the marine life. there is definitely a solution to these problems and i feel it is high time politicians stay out of it and solve it looking at the needs. defintely people like u should be allowed to suggest solutions and the water problem be solved amicably. Mr. President had also issued a solution of water problem by using rain water harvesting along the length of the road which was more that 20000kms. but dont know why he backed out of it. As u said not even 19% of rain water is being used efficiently. i dont know how far i am correct with these facts, correction is most welcome to these.
