Mountains Bind India, China, and Nepal to a Shared Destiny. They Need to Honour It, Pg13

Key Highlights:

• A recent catastrophe in Nepal, involving a sudden collapse of ice and rock, triggered a violent surge of water, mud, and debris.
• This disaster claimed over a thousand lives and destroyed critical infrastructure in the affected border region.
• Rabi Lamichhane, leader of Nepal's ruling Rashtriya Swatantra Party, emphasized the shared mountain system binding India, China, and Nepal.
• The tragedy is viewed as a direct consequence of accelerated global warming, disproportionately impacting Nepal despite its minimal greenhouse gas emissions.

Detailed Insights:

• The incident, likely a Glacial Lake Outburst Flood (GLOF) or a similar ice-rock avalanche, occurred along the Bhotekoshi river system.
• This event highlights the fragile and interconnected ecological reality of Himalayan Asia, where natural hazards transcend national borders.
• Historically, cooperation on ecological transparency and data sharing among upper-riparian and lower-riparian states in the Himalayas has been inconsistent due to national security concerns.
• China, as the upper-riparian state controlling the Tibetan Plateau, has often provided hydrological data transactionally rather than through open, automatic commitments.
• The article advocates for an institutionalized tripartite mechanism among India, Nepal, and China for ecological protection, real-time hydrological information sharing, and joint climate adaptation.
• Such a mechanism should include automated data protocols, joint ecological research and risk mapping, and collaborative engineering interventions for high-risk glacial lakes.
• Major transboundary rivers like the Yarlung Tsangpo (Brahmaputra), Indus, and tributaries of the Ganges originate in the Tibetan Plateau, making upstream data crucial for downstream safety.

Key Concepts Involved:

• Glacial Lake Outburst Flood (GLOF): A sudden release of water from a glacial lake due to the failure of its natural dam, often triggered by glacier melt, avalanches, or seismic activity.
• Upper-riparian state: A country or region situated upstream in a river basin, controlling the initial flow of water.
• Lower-riparian state: A country or region located downstream in a river basin, dependent on the water flow from upstream areas.
• Tripartite Mechanism: A collaborative framework involving three parties to address shared challenges and foster cooperation.
• Himalayan Biome: The distinct ecological region encompassing the Himalayan mountain range, characterized by diverse climates, ecosystems, and biodiversity.
