China's Massive Dam on the Brahmaputra River

The initiative is considered the largest infrastructure advancement of its type worldwide.

Project Information:

It includes five cascading hydropower facilities.

Total projected investment: 1.2 trillion yuan (approximately. USD 167.8 billion).

Projected energy output: 300 billion kilowatt-hours each year — sufficient to supply energy for 300 million individuals.

Location: Located in the Yarlung Tsangpo Grand Canyon (Brahmaputra in Tibet), where the river curves sharply near the India-China border before flowing into Arunachal Pradesh and eventually reaching Bangladesh.

The area experiences frequent seismic activity and has ecological significance.

Effect of the Project

Geopolitical Issues: India and Bangladesh are downstream nations.

Both depend significantly on the constant flow of the Brahmaputra for farming, potable water, and ecological balance.

Concerns focus on interruptions to water flow, obstruction of nutrient-dense silt, and possible harm to ecosystems.

It might also allow China to discharge significant volumes of water inundating border regions during conflicts.

Environmental Risks: Danger to biodiversity and river habitats, including aquatic life and wetlands.

Seismic and Structural Hazards: The Brahmaputra region experiences seismic activity, demonstrated by the 1950 Assam-Tibet quake.

A large dam in this area might lead to catastrophes such as dam failure and flooding caused by structural issues.

Geopolitical Strains: Dominance of water resources could escalate disputes between China and downstream nations (India, Bhutan, Bangladesh).

Disaster Susceptibility: Higher likelihood of Glacial Lake Outburst Floods (GLOFs), demonstrated by the 2023 Sikkim floods.

Coordination Framework for Collaboration Between India and China:

An overarching Memorandum of Understanding exists for collaboration on transboundary rivers, along with two distinct MoUs regarding the Brahmaputra and Sutlej.

The Brahmaputra MoU, which is renewed every five years, expired in 2023.

The overarching MoU was executed in 2013 and does not have an expiration date.

Since 2006, China and India have the Expert Level Mechanism (ELM) for sharing hydrological data, but they do not have a comprehensive treaty.

The Way Ahead

For transparent water-sharing agreements, China, India, Bhutan, and Bangladesh should increase their diplomatic communication.

Institutional Process: Create a transboundary river management authority that is permanent so that information about water flow, dam operations, and disaster forecasting can be shared.

Disaster Preparedness: Strengthen regional collaboration in disaster relief, including pooling resources.

India's Counter-Strategy: As part of its border and regional infrastructure development, India is speeding up its own hydropower projects on the Brahmaputra in Arunachal Pradesh.
