Lower the din – Aircraft noise a Pain for Residents around Airport

Aircraft noise a pain for residents around airport

Sahil yaduvanshi, 4, loves airplanes. He does not have to go far to look at one. He just has to peer out of his play school window and look up every few minutes to see one. “This is Cattie…,” he shouts out to his friend Pushpesh as he looks out. Sahil enjoys the sight of the planes, and wants to become a pilot when he grows up. His only complaint is to do with the roar of the planes. “I cannot hear my teacher and my friends because of the noise,” Sahil said. He studies in Aadyant pre-school in Vasant Kunj in Delhi. Most of his friends find it difficult to concentrate after a third runway—Runway 29—became operational at the Indira Gandhi airport in September 2008. “The children get disoriented as there is an airplane flying by every few minutes. We have to repeat lessons and even raise our voices to be heard,” said Bhavina Bembi, a school counsellor. Continue reading »

Losing Touch – Sabarmati Embankment project Ignores warnings, Precedents

November 29th, 2008

Sabarmati embankment project ignores warnings, precedents

Construction of an embankment along the 10-km stretch of the Sabarmati has begun in Ahmedabad despite warnings that it may hamper natural drainage in the city and that its design is inherently flawed. The 8.5-m-high embankment is part of the Sabarmati Riverfront Development Project, the first in India where the river will be squeezed to yield land for commercial, residential and open spaces. Project planners expect to recover the cost by selling this real estate.

The project’s Environment Impact Assessment (eia) report, however, said that embanking the Sabarmati would not just prevent drainage and “cordon the river away from the people”. It would also increase its speed, thereby increasing erosion that would affect the stability of the retaining walls and bridges. The report was prepared by the Ahmedabad-based Centre for Environmental Planning and Technology and the Gujarat Ecology Commission in Vadodara. Project designer hcp Design and Project Management Pvt Ltd, formerly called Environmental Planning Collaborative, said drains from low-lying areas would be directed to the river through underground channels. The riverfront project was proposed in 1997 to develop the banks into recreational zones. Continue reading »

Myth of power [Gangotri]

September 14th, 2008

Nourisher of an ancient civilization, the Ganga could be gasping for its survival. Every few kilometres the water of its tributaries will be diverted to produce power. While there may not be enough flow to run the turbines, there’s enough incentive for investors to set them up, find out Ravleen Kaur and Tom Kendall

Hydroelectric projects
in Alaknanda and Bhagirathi river basins

While going up the meandering road from Tehri to the holy town Gangotri during the thick of monsoon, the Bhagirathi appeared to get uneasily quieter with each hairpin bend; until Chinyali Sor village near Dharasu, 45 km from new Tehri town. The Tehri reservoir ends in the village. The river thereafter springs back to life and the roar of the gushing waters fills up the valleys. But the landscape gradually changes. Some of the mountains are bare and dotted along the road, every 500 metres, are graffiti, posters and signboards, giving out ominous messages. “Blasting Site” in bold, “Bandh Ganga ki hatya hai” (dams will kill the Ganga) and “Ganga ko aviral behne do” (let the Ganga flow unobstructed) are most common along this main stretch of pilgrim route where devotees go to pay their respects to Goddess Ganga, believed to be the daughter of heaven who came down on Earth through the matter locks of lord Shiva.

That apart, the river is fast becoming a favourite destination for hydroelectric projects, several of which are coming up on the Bhagirathi and Alaknanda basins (see map), tributaries of the Ganga river. The highest of them, Bhairon Ghati, is 27 km from the Gangotri glacier. The Uttarakhand government claims it needs the projects. “We do not have many resources except the rivers. Power from these rivers is the only source of revenue for the state. Besides, we can also control floods and have water for irrigation round the year,” said Yogendra Prasad, chairperson of Uttarakhand Jal Vidyut Nigam Limited (ujvnl) and adviser to the chief minister. Fifty five hydropower projects are in different phases of construction and planning. The 162 km stretch of the river from Gangotri to Devprayag will have 11 big dams while the 145 km stretch of Alaknanda from Badrinath to Devprayag will have more than nine big dams apart from several other small projects.

But things came to a head in June this year when G D Agarwal, former member secretary of the Central Pollution Control Board, sat on a nine-day fast. His demand was that no hydropower projects should come up on the 125-km stretch between Uttarkashi and Gangotri. He contended that it would affect the flow of the river and impact its purity. “Run of the river dams are the ones where water will be stored and released periodically through tunnels at locations on which the powerhouse will be built. If this goes on in a series, over long stretches there will be no flow in the channel,” says Agarwal. Following the protest, the state stalled two projects, Pala Maneri and Bhairon Ghati. The Union Ministry of Power has set up a committee to look into the questions raised by Agarwal. In response, B C Khanduri, chief minister of Uttarakhand, is reported to have said that “the state respects Agarwal’s sentiments and that he should also understand the state’s energy requirements”.

According to Anupam Mishra, environmentalist with Gandhi Peace Foundation,

“Engineers feel that a river meeting into the sea without being of use for irrigation or power is a waste of the water in it. If we disrupt the natural flow of a river, it can create havoc. Merging into the river prevents large quantity of saline water ingress. This is crucial but is considered unscientific. Also, they cannot predict that a strong earthquake won’t happen in the Himalaya. How will they save the downsteam areas from flooding if the dam breaks?”

Experts also say that the ecology of the area will be adversely impacted, the qualities that make the Ganga what it is will be gone and the river may dry up.
