Don't let borders blind us to Himalayan risks, Pg10

Key Highlights:

• Recent floods in Nepal, initially linked to Glacial Lake Outburst Floods (GLOFs), were found to be caused by an avalanche leading to a cascading debris flow.
• The incident highlights the transboundary nature of Himalayan hazards, emphasizing that risks like GLOFs transcend political borders.
• India's Parliamentary Standing Committee on Water Resources in 2023 recommended systematic data gathering, monitoring of glaciers, and transboundary agreements for glacier management.
• Past incidents include a 2014 landslide on the Bhote Koshi river and the 2023 South Lhonak GLOF in Sikkim, demonstrating cascading impacts.

Detailed Insights:

• The article advocates for a "geographical revanchism," reasserting South Asia as a unified ecological region for disaster management.
• Rivers in South Asia are not just water sources but also carriers of shared risks, necessitating a shift in geopolitical conversations.
• The 2014 Bhote Koshi incident saw India and Nepal collaborate to control a landslide-impounded lake, mitigating downstream impact.
• The South Lhonak GLOF in Sikkim underscored the speed and scale of Himalayan hazards affecting infrastructure and settlements.
• The Parliamentary Standing Committee on Water Resources identified the absence of a mechanism and provisions in existing treaties for glacier-linked risks.
• It urged the Ministry of Jal Shakti to engage the Ministry of External Affairs for agreements with neighboring Himalayan countries.
• The article suggests India can lead in convening regional cooperation for a Himalayan early-warning network and shared risk assessments.
• Reimagining water treaties and regional institutions is crucial to manage trans-territorial risks effectively.

Key Concepts Involved:

• Glacial Lake Outburst Flood (GLOF): A sudden release of water from a glacial lake, often caused by glacier melt, landslides, or earthquakes.
• Anthropocene: The current geological epoch, characterized by significant human impact on Earth's geology and ecosystems.
• Transboundary Risks: Hazards or issues that extend beyond the political borders of a single nation, requiring regional cooperation for management.
• Riparian: Relating to or situated on the banks of a river or stream.
