The new extreme reality of floods
Floods are destroying vast parts of the country because of how we have mismanaged our floodplains

It was way back in 1986 that Rajiv Gandhi had launched the Ganga Action Plan. But years later, after much water (sewage) and money has flowed down the river, it is as bad as it could get. Why are we failing and what needs to be done differently to clean this and many other rivers?
When I look back at 2013, I hear a cacophony. There was huge dissent about the way we are mismanaging coal reserves; the Supreme Court shut down iron ore mining in Goa; there was outcry about rampant sand mining and the havoc it is wreaking on rivers. There were equally loud calls for the need for green clearance to all projects, from hydropower projects in the Himalayas to mines in dense forests of central India. One side wanted to shut everything; another wanted to open up everything.
Engineers require re-training, not the Ganga. This is where I had left our conversation last fortnight. Why did I say this? The inter-ministerial committee I participated in as a member was discussing how much the ecological flow—the water that should be left in the river for ecosystem and livelihood purposes—should be at all times. How much water is needed for the river to be a river; and not a drain?
Hydropower is important. But how important? Is it important enough to dry up stretches of our rivers? Or is there a way to balance the need of energy with the imperative of a flowing, healthy river? I have been grappling with these issues for the past few months. But now that the committee (of which I was a member) on the hydropower projects on the Ganga has submitted its report, let me explain how I see the way ahead.
By: Bharat Lal Seth Use of groundwater accounts for 0.8 mm sea level rise Groundwater is becoming important to sustain agriculture, industry and drinking water. But as we exploit aquifers, more water becomes part of the hydrological cycle. A recent study shows evaporation and precipitation of groundwater is responsible for a fourth of the annual sea level rise of 3.1 mm.
