As soon as India
had indicated that it was planning to assert its rights within the Indus water
treaty versus Pakistan , China went public with its plan to build a large
dam with an investment of $740 million on Xiabuqu river close to the city of Xigaze .
Xigaze is a strategic location close to Bhutan and Sikkim
and is the town from where China
intends to extend its Beijing- Lhasa railway line up to Nepal .
Work on this dam started in June 2014 and will be completed
by 2019. But what has not been highlighted in India
is that China
is planning to build 55 reservoirs on the rivers flowing from the Tibetan
plateau.
Already, they have completed the Zangmu dam built on the
upper reaches of the Brahmaputra in 2010. Three
more dams at Dagu, Jiacha and Jeixu are presently under construction while In 2015,
work started on the Zam Hydropower station which will be the largest dam built
on the Brahmaputra .
Another ambitious Chinese project is to build a dam on the
Tsangpo (Brahmaputra) before it enters Assam .
The origins of the river are from a glacier in western Tibet close to the origins of the Indus and
Sutlej rivers, all of which emanate from the holy land of Lake
Mansarovar and Mount Kailash .
Medog, which has been selected as the site of this mega project as the river, makes
a huge bend inside a giant canyon which is around 198-miles-long and 3.1-miles-long.
Medog incidentally is located just 30 km north of the Indian border.
The Chinese have moved the entire team which built the Lhasa-Beijing
railway line to execute this mammoth project which will involve the
construction of massive tunnels and reservoirs and turbines in order to
generate 40,000 MW of power.
The first hint of this scheme emanated from an official
Chinese newspaper in the 1990s pointing out that the Chinese wanted to exploit
the spectacular 2,000-metre-drop in the river to generate electricity.
This will be constructed before the river flows into
Arunachal Pradesh and the water of the Tsangpo is expected to be diverted to
water the vast, arid areas of Xingjian region and the Gansu province.
Water experts insist the ministry of external affairs and
the ministry of water resources must start negotiations for an international
treaty on the Brahmaputra before north-east India is subjected to major water
scarcity.
Dr. Chandan Mahanta, an expert on the Brahmaputra
river basin who heads the Centre for Environment at IIT Guwahati, believes the
ministry of water resources must set up the Brahmaputra River Valley Authority (BRVA)
at the earliest.
Mahanta pointed out that with China
building four dams on the Brahmaputra, it was imperative for such an
organisation to undertake a comprehensive study of the Brahmaputra
basin.
“There is no clarity about the nature of dams being
constructed by the Chinese who claim they are building run-of-the-river dams. The
Indian government is going by that assurance but the people in Assam
have serious doubts about the Chinese plans,” said Mahanta.
“We need to undertake a sound scientific investigation about
both the lean flows of the river and how the dam construction by the Chinese
will affect the river. We feel that once the dams are in place, the Brahmaputra will become a seasonal river causing water
scarcity in our region,” he said.
“Such an apprehension is being expressed by people throughout
Asia who want to know just how much water the
Chinese plan to divert across Asian rivers,” Mahanta said demanding that a
bilateral collaborative study between the two countries will help allay these
fears.
Mahanta pointed out, `No proper flood mitigation measures
are in place and as a result, the excess water in the Brahmaputra
is not contained in any reservoir. This is in contrast to the river Ganga which has several reservoirs being used to irrigate
canals.”
The Assam
government has expressed apprehension over the fallout of the construction of
dams in Arunachal Pradesh. India
and China have an agreement
on sharing the data of the Brahmaputra water but do not have any treaty similar
to India and Pakistan
on the sharing of the river waters.
In 2013, India
complained to China about
the hydro projects on the Brahmaputra . Union
water minister Uma Bharti has expressed her reservation about these Chinese
moves as she believes this can adversely affect both India
and Bangladesh
.
It is for this reason that the Indian government is pressuring
China
to set up a joint water commission or work towards having a joint water sharing
treaty following an inter-governmental dialogue on this subject.
