Conserve lakes, curb illegal constructions to prevent urban

Press Trust of India  |  Hyderabad 

Disallowing unauthorised constructions in low-lying areas, conservation of lakes and putting in place a good system are some of the major steps needed to prevent disasters due to urban flooding, said experts.

Urban flooding is a global phenomenon and is caused by climate change, they said.

"It (urban flooding) is a phenomenon which is caused due to climate change. Unless and until we take all the safeguards, it will not be possible to really check urban flooding," D S Meshram, President Emeritus, Institute of Town Planners, (ITPI), told

He was here to take part in the 66th and Country Planners held last week.

"Unauthorised constructions and encroachments in low- lying areas should not be allowed," said Meshram, a former Chief with the

Heavy rainfall can occur all of a sudden due to climate change and a system should be in place to let the drain, he said.

said plans should be prepared in advance to immediately evacuate people living in vulnerable areas (to safer places) in the event of a heavy downpour.

Urban flooding is witnessed not only in but in several other countries as well, he said, citing a report of the

According to the report, he said, there are 10 cities in the world, including Tokyo, and Mumbai, which are vulnerable to urban flooding.

A N Sachithanandan, a retired professor in urban planning with Anna University, Chennai, said lakes in cities and other places should be conserved to preserve the natural ecosystem.

Regretting that lakeshave shrunk in several urban centres in the country due to encroachments and other reasons, he said lakes in the old days had channels for flow of

"We should whole-heartedly preserve the lakes. (In recent times) the channels are blocked because of encroachments," he said.

Talking about the importance of system, he said, "If you have enough to drain (water) instead of stagnating, then things can happen."

Most of the new office buildings, including in the IT sector, cover the whole area with cement, leaving little space for absorption, he said.

"If is flowing, before it goes there, half of it would have been absorbed here (if it is not covered by cement).

"The speed of water that goes there will be less and quantity will also be less. Simple logic. We don't require a to tell this," he said.

Observing that authorities do insist on following the rules in construction of buildings, he said individuals, private companies and others should have the awareness not to "pave" (cover the area with cement) the whole area.

"How can authorities see whether every family, every office building are following (rules) or not. Individuals should become conscious that he is polluting, he is flooding," he said.
