Himalayan Disaster Risk: Causes and Profile |
Natural Causes |
Human-Induced Causes |
Institutional & Social Gaps |
- Geological Fragility: Young fold mountains, unstable slopes, active fault lines (e.g., Dhaulagiri, Indus–Ganga).
- Geological Survey of India (GSI, 2023): 70% of India’s landslides occur in the Himalayas.
|
- Unplanned Development: Road widening, hydropower tunnelling, unchecked tourism, urbanisation in fragile zones.
|
- Weak Early Warning Systems: Patchy real-time monitoring, delayed alerts (e.g., Uttarakhand 2025 floods).
|
- Seismic Activity: Seismic Zones IV & V are highly prone to earthquakes, triggering landslides and avalanches.
|
- Deforestation and Mining: Reduced slope stability, soil erosion, and blocked drainage channels.
|
- Governance Complexity: Multi-agency overlap (district, state, and central levels) slows coordination and response.
|
- Hydro-Meteorological Hazards: Cloudbursts, flash floods, and Glacial Lake Outburst Floods (GLOFs).
- National Remote Sensing Centre (NRSC, 2022): 329 potentially dangerous glacial lakes mapped.
|
- Encroachment in Riverbeds and Floodplains: Increases vulnerability (e.g., Dharali flood 2025).
|
- Healthcare and Resource Gaps: Remote, marginalised communities lack medical infrastructure and resilience capacity.
|
- Climate Change Multiplier: Warming at twice the global average, glacial retreat, unstable lakes, and erratic monsoon rainfall.
- India Meteorological Department (IMD, 2023): 200% rise in cloudburst incidents in Uttarakhand since 2010 (e.g., Dehradun 2025 record rainfall).
|
- Pilgrimage Pressure: Overcrowding on vulnerable routes (Char Dham, Gangotri).
|
- Low Public Awareness: Citizens often ignore alerts; mock drills remain tokenistic.
