Report: Impact of China’s Mega-Dam on Tibet’s Ecology

China’s plan to construct the world’s largest hydropower dam on the Yarlung Tsangpo River in Tibet has raised significant environmental and geopolitical concerns. This report examines the potential ecological impacts on Tibet’s unique environment.

Project Overview

The proposed dam, part of China’s 14th Five-Year Plan, aims to generate 300 billion kilowatt-hours of electricity annually, surpassing the capacity of the Three Gorges Dam. Located on the lower reaches of the Yarlung Tsangpo River, where it curves towards India’s Arunachal Pradesh, the project is estimated to cost around USD 137 billion.

Ecological Concerns

1. Disruption of River Ecosystems: Damming the Yarlung Tsangpo will alter natural water flow, affecting aquatic habitats and species reliant on the river’s dynamics. Changes in sediment transport can lead to erosion and loss of fertile lands downstream.
2. Biodiversity Loss: The region is home to diverse flora and fauna, some endemic to the Tibetan plateau. Construction activities and subsequent environmental changes could threaten these species, leading to potential extinctions.
3. Seismic Risks: The Tibetan plateau is seismically active. Large-scale construction, like this mega-dam, may increase the risk of earthquakes and landslides, posing dangers to local communities and ecosystems.
4. Impact on Downstream Communities: Altered water flow can affect agriculture, fisheries, and livelihoods of communities downstream, including those in India and Bangladesh. Potential for flash floods or reduced water availability raises humanitarian and ecological concerns.
5. Cultural and Social Displacement: The dam’s construction may lead to displacement of local Tibetan communities, disrupting their traditional lifestyles and cultural heritage.

Conclusion

While the dam promises substantial energy generation, the potential ecological and social costs are profound. Disruption of river ecosystems, biodiversity loss, seismic risks, and impacts on downstream communities highlight the need for comprehensive environmental assessments and transparent international dialogue. Balancing development with ecological preservation is crucial to safeguard Tibet’s unique environment and the well-being of millions dependent on the Yarlung Tsangpo-Brahmaputra River system.
