A Himalayan Power Play
China's construction of a massive dam on the Yarlung
Tsangpo River (the Brahmaputra in India) raises serious concerns for downstream
nations like India and Bangladesh. This project, part of China's 14th Five-Year
Plan, has the potential to disrupt water flow, exacerbate flood risks, and
serve as a strategic tool for Beijing during times of conflict. The dam's
scale, exceeding even the Three Gorges Dam, makes its implications particularly
significant.
The Yarlung Tsangpo: A River of Extremes
Originating in the glaciers of western Tibet at an altitude
of 5,000 meters, the Yarlung Tsangpo is the world's highest river. Its dramatic
course through the Himalayas includes the Yarlung Tsangpo Grand Canyon, a gorge
more than twice the depth of the Grand Canyon in the United States. This unique
geography makes it an attractive site for hydroelectric power generation.
A Dam of Unprecedented Scale
The proposed dam's construction cost is estimated at $137
billion, surpassing the $34.83 billion spent on the Three Gorges Dam. With a
projected annual electricity generation capacity of 300 billion kilowatt-hours,
it will dwarf the Three Gorges Dam's 88.2 billion kWh output. This massive
project aligns with China's goals for carbon neutrality by 2060 and aims to
boost related industries and employment in Tibet.
China's History of Dam Construction and its
Environmental Impact
China has a long history of large-scale dam construction,
with over 22,000 dams exceeding 15 meters in height built since 1950. While
projects like the Three Gorges Dam offer benefits like clean energy, flood
control, and improved navigation, they also raise serious ecological and social
concerns. These include biodiversity loss, displacement of millions of people,
increased risk of landslides and sedimentation, and destruction of downstream
habitats.
The Super Dam Project: Engineering and
Environmental Challenges
The new dam project, under development for over a decade,
faces significant engineering challenges due to its location on a seismically
active tectonic plate boundary. While Chinese authorities assert the project's
safety, concerns remain about the potential for earthquakes, landslides, and
ecological damage. The scale of potential displacement, though unknown, draws
parallels with the Three Gorges Dam, which displaced 1.3 million people.
India's Concerns: Water Security and Strategic
Implications
The Yarlung Tsangpo is crucial for the water security of
millions in India, Bangladesh, and Bhutan. India's primary concerns regarding
the dam are:
- Water
Flow Reduction: The dam could significantly reduce
downstream water flow, especially during the dry season, potentially
impacting agriculture and livelihoods.
- Weaponization
of Water: The dam gives China the ability to
control water flow, potentially using it as a strategic weapon by
releasing large volumes of water during times of conflict or during
India's monsoon season, exacerbating floods.
- Ecological
and Environmental Risks: The dam's location in an
earthquake-prone zone poses risks of dam failure, flash floods, and other
ecological disasters.
- Hydropeaking
Impacts: Fluctuations in water release for peak
electricity demand (hydropeaking) can negatively impact downstream river
ecosystems.
The Lack of a Water Treaty and China's Stance
The absence of a bilateral water treaty between India and
China exacerbates these concerns. China's reluctance to engage in meaningful
discussions and its disregard for international conventions on equitable water
use further complicate the situation. There are also concerns about China's
plans to divert water to its parched northeast.
Past Warnings and China's Defense
In 2016, an Assamese NGO warned of China's plans for
numerous dams and water diversion projects, predicting significant reductions
in water flow to India. While China defends the project, stating it will not
negatively affect downstream nations and that safety concerns have been
addressed, skepticism remains.
The Need for Action: Transparency and
International Cooperation
India and China have an agreement for data sharing on the
Yarlung Tsangpo, but China has withheld this data in the past during periods of
tension. India needs to take proactive steps to protect its interests,
including pursuing bilateral negotiations and seeking international cooperation
to ensure transparency and accountability in China's dam projects. The lack of
transparency in China’s planning and operation of dams is a major concern. The
Brahmaputra's massive hydroelectric potential is a powerful incentive for
energy-hungry China.
