Fragile Ecology, Competing Interests: The Red Flags In Building Himalayan Dams, Pg15

Key Highlights:

• A glacier collapse near the China-Tibet border triggered devastating floods in Nepal, resulting in over 1,100 deaths.
• Experts attribute the increased disaster risk in the Himalayas to its naturally fragile geology, climate change, and extensive hydropower development.
• Over 193 dams are built or planned across the wider Tibetan region, with Nepal listing more than 570 projects at various stages.
• China's mega-dam on the Yarlung Tsangpo river is part of a larger geopolitical dynamic, prompting similar dam constructions by other Himalayan nations.
• Inadequate transboundary communication and data sharing among Himalayan nations impede effective disaster mitigation and planning.

Detailed Insights:

• The Himalayan topography, characterized by melting glaciers, fast-flowing rivers, and steep slopes, is highly vulnerable to earthquakes and climate change.
• Climate change increases underlying vulnerability by affecting the pace and frequency of natural processes, including Glacial Lake Outburst Floods (GLOFs).
• Hydropower projects, while providing services, increase geological vulnerability, making areas more prone to earthquakes due to extensive drilling and tunneling.
• Recent floods affected 13 hydropower plants, impacting regional power generation capacity and access.
• China's infrastructure building in Tibet, including the Yarlung Tsangpo mega-dam, is viewed as a sovereignty marker, leading to counter-signaling through dam projects by India, Nepal, and Bhutan.
• Chinese researchers have flagged an active fault line directly beneath the Yarlung Tsangpo mega-dam, raising seismic concerns.
• A Memorandum of Understanding between India and China in 2002 led to an expert-level mechanism on transboundary rivers in 2005, which needs expansion to include aspects like GLOFs.
• Transparency in project information varies significantly, with Nepal providing detailed data while China's information remains scattered across different official documents.
• Continuous sharing of hydrological, weather, and climate data, along with co-investment in upstream observation systems, is crucial for effective early warning systems.
• A nation-state-centric approach is ineffective for Himalayan disasters, necessitating a landscape perspective for sustainable infrastructure development and scientific research.

Key Concepts Involved:

• Glacial Lake Outburst Floods (GLOFs): Sudden release of water from a glacial lake due to dam failure, often caused by rapid melting of glaciers.
• Active Fault Line: A fracture in the Earth's crust where movement has occurred in recent geological times, indicating potential for future earthquakes.
• Transboundary Rivers: Rivers that flow through or form the border between two or more countries, requiring international cooperation for management.
