⚡ China's Medog Hydropower Dam: A Mega Project with Regional Implications

A major geopolitical and environmental development is unfolding along the Yarlung Tsangpo River (known as the Brahmaputra in India). China has begun construction on the world’s largest hydropower dam—the Medog Hydropower Station—in Medog County, Tibet.

This region is strategically and environmentally significant. As per reports, within just a 50 km stretch, the river drops nearly 2 km in altitude, offering massive hydropower potential. China plans to harness this gradient by building a series of turbines—a project even larger than the Three Gorges Dam.

But the concern isn’t about scale—it’s about transparency and regional impact.

🌏 The Yarlung Tsangpo becomes the Brahmaputra as it enters Arunachal Pradesh, flowing through northeast India and into Bangladesh (as the Jamuna). It is a lifeline for millions—supporting drinking water, irrigation, and agriculture.

However:

India and China lack a formal water-sharing treaty.

China has built multiple dams upstream with limited data sharing.

There is no clear hydrological cooperation, especially during monsoons or floods.

With China now initiating work on this multi-billion dollar dam, downstream countries like India and Bangladesh face uncertainty regarding:

Water availability

Flood management

Ecological disruptions

As transboundary rivers become a strategic asset, the need for transparent agreements, trust, and cooperation becomes more critical than ever.
