Uttarakhand Warning
SHOULD DAMS BE DAMNED?
By Shivaji Sarkar
It was
waiting to happen, since 1960s. No sane advice of environmentalists, activists
or religious leaders was heard by the Government. Uttarakhand is still sitting
on a powder keg. The losses, the cost of rebuilding the roads and
infrastructure, as per the State government estimates are around Rs 21,000
crore, and sought from the Centre as a package.
This estimated
package would be only a fraction of the cost the State is planning to invest in
more “planned development”. Tehri dam alone had cost about Rs 10,000
crore. In all there are 244 hydel
projects of various sizes are planned to be constructed in the State.
Uttarakhand has
lost over 2000 lives, over 5000 reported missing, several thousand heads of
cattle, livelihoods of lakhs, 1000 km of roads, about 300 bridges, thousands of
private and Government houses and many other infrastructure. Not all can be
estimated in terms of money. Damage to 10 power plants would be about Rs 20,000
crore.
What has
happened is a planned disaster and not development. The proposed Pancheswar dam
being planned in Tanakpur in the Uttarakhand-Nepal border is likely to be
bigger than Tehri and biggest in India. Does that mean more
disasters are awaiting the region?
The big
question to be asked is--should we really have dams? These hold water during the
summers keeping people in its riparian area thirsty and submerge them during
rains as these cannot hold on to the excess water. Ironically, dams damn the
fate of the common man and fill the pockets of rich be it the power lobbies or
the industry mafia.
The June 18
cloudburst has been the worst since the 1978 Alaknanda tragedy. It was then
caused as a large landslide blocked the flow of the river and heavy rains led
to flash floods in a 300 km region up to Hardwar.
In fact, the
statement of Tehri Hydropower Development Corporation (THDC) on June 19 indicates
that the worst is yet to be averted. It stated that it had to withhold 2.5 lakh
cusecs of water that poured in the dam and released only 17.6000 cusecs. Had
all been released the townships of Rishikesh and Hardwar would have been wiped off!
This does
not mean Tehri has been a saviour. The dam facing high siltation does not have
the capacity to withhold that huge body of water. It has been releasing it later
causing flash floods in many areas of Uttar Pradesh up Allahabad. The Tehri cannot repeat it as huge
body of water could lead to the rupture of the dam and may be a worse
recurrence of the 1978 tragedy.
The dams
itself are the worst hit questioning the wisdom of building these on such
critical regions. Among the hydro power projects that are washed away
include Asiganga-I (45 MW) and Asiganga-II (45 MW) in Uttarkashi district and Kaliganga-II
(6MW), Madmaheshwar (15 MW) in Rudraprayag district of Uttarakhand and 8 MW
hydro project Sobla-I in Pithoragarh district. Besides, Maneribhalli-I (90 MW),
Maneribhalli-II (34 MW, Pilangad (2.25 MW) in Uttarkashi district, Badrinath-II
(1.25 MW), Pandukeshwar (750 KW), Urgam (3 MW), Tharali (400 MW) in Chamoli
district, Kanchotti (2 MW),Chirkilla (1.5 MW), Relagaad (3 MW) in Pithoragarh
district and Kaliganga-I(4 MW) in Rudraprayag district are said to be badly
damaged.
Recall that a cloud
burst had swept away bridges and a large chunk of the Gangotri national highway
in 2012 as well as in Rudraprayag and Chamoli districts. In 2010, a similar
flooding had occurred in the region. The phenomenon, states a UNDP and European
Commission joint study in the Sutlej basin in
Himachal Pradesh, an adjacent region, is apparently repeating. It revealed
“glacial lake outburst floods” (GLOF) had been occurring “quite regularly”.
Notable incidents occurred in 1997, 2000 and 2005 in the Sutlej
basin and in 1970 and 1978 in Alaknanda and Bhagirathi basins, with 2000 and
2005 being the worst. Worse, incidents of GLOF are reported in Sikkim, Ladakh,
Jammu and Kashmir, Himachal and
Arunachal Pradesh.
Environmentalists warn that a delicate ecological
balance in the area has been gravely imperilled and that up to 26 km of
riverbeds along the Alaknanda and Bhagirathi have begun to dry up. In the case
of Alaknanda, the tragedy unfolded soon after the Uttarakhand Government
cleared the construction of a 12-km-long tunnel and a four-storeyed
hydro-electric project in Chamoli about two years ago. The explosives used to
build the project in the nearby river area and the debris of the construction
material played a major role drying up of the riverbed.
The swelling of the
Alaknanda river on June 18 is attributed to this and the Vishnuprayag dam,
which burst open changing the local topography on the road to Badarinath.
Importantly in
2009, the CAG reviewed 42 hydel projects and noted that over 200 more
projects were coming up – almost at every 5 to 7 kms. The yearning for making
Uttarakhand the “Urja Pradesh” has sadly paved the way for disaster. The river bed is being
used by the construction lobby for dumping of debris and is heightened by unsustainable
concrete constructions on the edges of mountains and river banks.
The large dams led to timber lobby felling
of lakhs of trees and warming the region. Deforestation and tunnelling for
hydel project loosened the fragile Himalayan structure, says a 2003 report of the
UN Environment Programme.
There is need for a detailed study
as to why the Kedar Dome, sub-peak of Kedarnath
Mountains, burst, first time in known history, which led to the flash floods. It led to the rupture of Charbari Lake,
less than 6 km from the shrine, after a cloud burst. This apart, the rain has
been incessant—it was 315 mm as against normal rainfall of around 70 mm in
June.
The UNEP and UNDP
reports are speaking of climate change being heightened by irrational human
activities. These also question the formation of the smaller State of Uttarakhand. As long as
it was part of Uttar Pradesh, environmental norms were strictly adhered to.
During the past 12-odd years, a pliable political leadership in collusion with
the corporate-contractor lobby has thrown the norms to the wind in the name of “development.”
Most hydel projects have been undertaken without assessing their impact on
environment, hence the huge devastation.
Even in Delhi over 70 per cent of the Yamuna bed has been occupied
illegally and semi-legally, including the Commonwealth Games
Village. This is against
the Central Water Commission’s recommendation way back in 1981 warning against
any construction on the river bed and its catchment areas. But who cares?
The Uttarakhand devastation
is a lesson for the Governments. It is not restricted to Himalayas.
It has happened in Morbi in Gujarat, Koyna in Maharashtra and very recently on
the Krishna in Karnataka. The reasons were similar--
blocking of the rivers natural path.
It raises the moot
question-- is it possible to have a national policy to maintain the perennial
flow of the rivers? Hydel power is neither cheap nor easy to harness except
possibly the run of the mill sort. Can we think of giving it up at least in
delicate zones and spare the nation both human and economic disasters? ---INFA
