📰 Editorial Focus – Himalayan Disasters and the Growing GLOF Threat

Editorial Theme

The Nepal disaster demonstrates how glacier collapse, unstable mountain terrain and temporary river blockages can combine to produce catastrophic downstream flooding.

Climate change is increasing risks from natural outbursts in mountainous regions, while development projects, dams and settlements in fragile valleys remain highly exposed.

Key Issues

• Glacial Lake Outburst Floods
• Glacier collapse
• Remote sensing
• Western Disturbances
• Climate change
• Hydropower vulnerability
• Construction in fragile zones
• Glacier-health monitoring
• Early-warning systems
• Transboundary Himalayan cooperation

Why is the Debate Important?

The Himalayas contain thousands of glaciers and glacial lakes, while major settlements, roads and hydropower projects are located downstream. This makes disaster-risk reduction a core development challenge rather than merely a post-disaster relief issue.

Key Concepts for UPSC

• GLOF
• Cryosphere
• Remote Sensing
• Climate Adaptation
• Disaster Risk Reduction
• Early Warning
• Himalayan Ecology
• Resilient Infrastructure

Mains Takeaway: Himalayan disaster policy must move from reactive rescue towards risk-informed development through glacier monitoring, zoning, stronger construction standards and climate-resilient infrastructure.

⛽ Prelims Concept – Strategic Fuel Reserves

What are Strategic Fuel Reserves?

Strategic reserves are emergency stocks of fuels maintained to protect the economy during war, geopolitical disruption, import shortages or major supply-chain shocks.

Important Terms

• Crude Oil: India’s most developed strategic-storage system.
• Phase I: 5.33 MT underground crude capacity.
• Locations: Visakhapatnam, Mangaluru and Padur.
• Phase II: Additional 6.5 MT approved at Chandikhol and Padur.
• LPG: India already has underground LPG caverns but limited capacity.
• Natural Gas: India currently has no operational underground natural-gas storage facility.
• LNG: Liquefied natural gas is stored at about -162°C.
• Regasification: Conversion of LNG back into gaseous natural gas.

Prelims Trap: LNG regasification capacity and strategic LNG inventory are not the same thing. A terminal may have large regasification capacity without holding an equivalent strategic stock.
