INNOVATION KEY TO PROTECT LAKES - Metro India, New Paper published on 28th January 2015

Metro News / Hyderabad : Eminent environmental scientist N Sai s on Tuesday said that in addition to desilting and repairing tanks for irrigation purposes, there is a need for employing innovative methods to save other water bodies, especially lakes, in the state from being destroyed due to pollutants. Speaking to Metro India after presenting his views on conservation of water bodies at a national seminar that concluded here on Sunday, he proposed to the State government to consider 'Floatation' model for saving urban lakes from nitrogen pollution and eutrophication.

-Release of organic matter into lakes and ponds is a very common problem in cities. This leads to accumulation of huge amounts of nitrates in the water which in turn causes to growth of algae. Eventually, the water bodies get eutrophicated and its ecosystem dies
-“When people develop a personal association with lakes, then nobody needs to tell them not to spoil. So, if people get to swim, fish, boat and drink the water of a lake, they would not litter around it,“
he said


Innovation

A model developed by Reddy himself, 'Floatation' aims to neutralize the nutrient imbalance in water bodies by allowing plants to absorb excessive nutrients in water through capillary action while floating on it. “Release of organic matter into lakes and ponds is a very common problem in cities. This leads to accumulation of huge amounts of nitrates in the water which in turn causes to growth of algae. Eventually, the water bodies gets eutrophicated and its ecosystem dies,” he explains.

The environmentalist says that in addition to absorbing pollutants from water bodies, the floatation plants will add to the aesthetics of urban lakes thereby attracting more tourists. “When people develop a personal association with lakes, then nobody needs to tell them not to spoil it. So, if people get to swim, fish, boat and drink the waater of a lake, they would not litter around it,” says Reddy, who was featured by CNN in 2013 for discovering the use of biomass charcoal in fertilizing the soil.

Sai Bhaskar Reddy adds that the easiest way to know whether a water body has been polluted or not is to check if there are any fish living in the water. “It was a part of our traditional knowledge that whenever you are faced with the doubt of whether to drink the water from a lake or not, decide by checking if there are fish living in it. Also, you will have birds around a fresh water lake as they come to catch the fish. So, the signs of a healthy lake are pretty simple,” he observes.
Reddy opines that the State government's plan to empty the Hussain Sagar Lake for cleaning it up is technically sound.

“The water in Hussain Sagar is highly contaminated. So, it is better to dry it up completely, desilt and fill it with fresh water from excess waters in Krishna or Godavari river that gets help up as dead storage in our projects,” he added. Reddy was instrumental in obtaining injunctions against environment polluters in the State through Public Interest Litigations (PIL) in Supreme Court.
