Tibet’s
Rivers Will Determine Asia’s Future
At the dawn of a new era of building dams on the Yarlung
Tsangpo, countless lives and ecosystems are being risked in the name of
“development” and geopolitics.

Over the last seven decades, the People’s Republic of
China has constructed more than 87,000 dams. Collectively they generate 352.26 GW of power, more than the capacities
of Brazil, the United States, and Canada combined. On the other hand, these
projects have led to the displacement of over 23 million people.
The Tibetan plateau is a rich
repository of indispensable freshwater resources that are shared across Asia.
After damming most of its rivers, China is now casting its eyes on the major
international rivers flowing out from the Tibetan plateau, heralding a new era
of damming Tibet’s rivers.
Tibet, known as the “Water Tower of
Asia,” serves as the source of 10 major Asian river systems flowing into 10
countries, including many of the most densely populated nations in the world:
China, India, Vietnam, Cambodia, Laos, Thailand, Burma, Bangladesh, Nepal,
Bhutan, and Pakistan.
China, through its political control
over Tibet, has complete upper riparian control over all major rivers flowing
out of the Tibetan plateau. Compared to China, Tibet remains a virgin territory
with less than 0.6 percent of its hydropower resources being utilized for
developmental purposes. But this is changing rapidly. As China seeks to meet
its renewable energy targets, Beijing will have to harness yet more hydropower.
Chinese hydropower and energy companies have been lobbying the government to
allow more hydropower projects to tap into Tibet’s fast-flowing rivers, with as
many as 28 proposals awaiting approval.
Tibet is a geologically unstable
region with an average elevation of 4,500 meters above sea level (14,800 feet).
Despite the critical state of the Tibetan plateau
which remains ecologically sensitive and seismically active, China is still
moving on with its ambitious plan to expand the hydropower generation on the
headwaters of Asia’s major rivers — the Yangtze, Yellow, Brahmaputra, Indus,
Mekong, and Salween Rivers.
China’s State Council’s energy plan
for the 12th Five-Year Plan (2011-15) and 13th Five-Year Plan (2016-2020) confirm
the government’s intentions to vigorously push forward the hydropower project
on the Tibetan plateau. Hydropower is being promoted as the centerpiece of
China’s plan to expand its renewable energy sector. By 2020, China wants to
triple its hydropower capacity to 300 GW. Therefore it is increasingly damming
transboundary rivers to achieve its hydropower targets.
The Brahmaputra, know as the Yarlung
Tsangpo in Tibetan, is a major international river shared between Tibet, India,
and Bangladesh. It stretches over a total length of 1,800 miles (2,900 km) from
west to east, starting on the Tibetan plateau from its source, the
Chemayungdung glaciers near the sacred Mount Kailash.

Once a free-flowing river, it is now
dammed on every section. Starting from Zangmu hydroelectric power station,
there has been a cascade of dams being built on the Brahmaputra. Geologist Yang Yong had rightly said that
the activity represents “the start of a hydropower era for Tibet’s rivers.”
In January 2013, China approved
three dam projects on the Brahmaputra River as part of its 12th Five-Year Plan,
which triggered concerns in the Indian media about the possible impact on
downstream flows. In an attempt to downplay India’s concern over these
matters, the Chinese government was quick to
assure India that the project will be planned and reasoned scientifically. It
maintained that the project was a Run-of-River (ROR) hydroelectricity
generation project – meaning a part of the river was being diverted to run past
electricity generating turbines, and then the water would flow back to join the
river. Such a ROR project would, according to that argument, not reduce the
water flow and not have any impact downstream.
These assertions are largely untrue.
Instead, ROR projects require storing large volumes of water during the day,
only to be released all at once in the evening for generating power during peak
energy demand. These daily fluctuations in the river cause an incredible
disruption to the river ecology. Moreover, large dams also increase the
probabilities of earthquakes, destroy precious environments, and shatter the
lives of millions of people who are dependent on the Brahmaputra River.
Rather than benefiting populations
with non-polluting power, China’s dam builders are making a Faustian
bargain with nature, selling Tibet’s soul in their drive for economic
growth. Taken together there is much scientific evidence that dams are not
the clean, green, or cheap source of electric power they are often made out to
be.
DIPLOMAT BRIEF
It is no surprise that China has
begun the construction of three hydropower dams (Dagu, Jiexu, and Jiacha) on
the middle reaches of the Brahmaputra. The Dagu (660 MW) and Jiexu (560
MW) dams are being constructed upstream of Zangmu and the Jiacha dam (320
MW) downstream of Zangmu — all located within a few kilometers from each other.
The Zangmu hydropower station (510 MW) is
only the start. China plans to build 11 hydropower stations on the Brahmaputra
mainstream and several on its tributaries. Huaneng, Huadian, Guodian and Datang
— four major power generation groups — have already taken root in Tibet. Among
them, Huaneng is the largest hydropower development in the Tibet
Autonomous Region (TAR).
Huaneng Tibet Power Generation Co.
Ltd. (HTPG), a subsidiary of the state-owned China Huaneng Group, has signed
multiple agreements with the TAR government regarding the development of clean
energy in the region. According to the agreements between the company and the
regional government, Huaneng’s installed capacity in Tibet
will reach 10,000 megawatts by 2020. It is believed that hydropower resources
in the TAR account for 29 percent of the national total.
According to the plan, Huaneng Group
is responsible for the development of the Jiexu and Jiacha hydropower stations
whereas Dagu was constructed by Huadian group.
In addition, the Bayu hydropower
station began its survey in November last year. The installed capacity of that
power station is 800 MW.

From time to time, whenever water
issues such as floods and other disasters occur in the region, India raises its
concerns to Chinese counterparts. Those concerns are met with a Memorandum of Understanding (MoU) or
Expert Level Mechanism (ELM), which remains nonbinding and without any governing
body that ensures their implementation.
China has so far not communicated
officially about the construction of these dams on the Brahmaputra. A lack of
transparency about dam building on the Tibetan river raises questions about
whether the Tibetan people and the downstream countries were fully informed
about the risk and impacts on a river system that supports millions. These
proposed dams will pose a serious ecological threat not only to the Tibetan
plateau but also to the other side of the border. China, by constructing these
dams, will be responsible for the overexploitation of the river, which can
jeopardize the river ecosystem as well as alter water flows downstream,
affecting the farmers and fishermen of India and Bangladesh.
Moreover, China can also easily
manipulate the river flow, which puts India at a strategically disadvantageous
position. It is high time for India to take a stand in order to ascertain their
user rights on the river and monitor those dam activities on the upper part of
the Brahmaputra River.
The environmental health of the
Tibetan plateau is critical for around 1.3 billion people who live in the river
basins downstream in Asia. The Tibetan river shouldn’t be seen only as a source
of hydropower; its geological significance should also be taken into serious
consideration.
