Vulnerability Profile of India in Disaster Management

India has a high level of vulnerability to natural and human-induced disasters because of its diverse geo-climatic conditions, large population, rapid urbanization and socio-economic disparities. Nearly 85% of India's landmass is vulnerable to one or more natural hazards, while more than 75% of the regions face multi-hazard risks. The major hazards affecting India include earthquakes, floods, droughts, cyclones, tsunamis, landslides, avalanches and human-induced disasters.

Earthquake Vulnerability:

Approximately 58.6% of India's landmass is vulnerable to moderate-to-high intensity earthquakes. The Himalayan region is particularly vulnerable because of active tectonic processes. The Andaman & Nicobar Islands are also exposed to significant seismic activity. Earthquake risk is increased where dense settlements and poorly designed or constructed buildings are located in hazard-prone areas.

 Flood and River-Erosion Vulnerability: 

Around 12% of India's land area, covering more than 40 million hectares, is prone to floods and river erosion. The Indo-Gangetic and Brahmaputra plains are particularly vulnerable because of extensive river systems, heavy monsoon rainfall, sediment deposition and river-channel changes. Flooding can cause loss of life, damage to infrastructure, displacement and agricultural losses.

Drought Vulnerability:

Approximately 68% of India's cultivable area is vulnerable to drought. Drought risk is particularly important in central, western and peninsular India, where agriculture is heavily dependent on monsoon rainfall. Erratic rainfall, prolonged dry periods and changing climatic conditions can increase agricultural and livelihood vulnerability.

Cyclone and Tsunami Vulnerability: 

India has a coastline of approximately 7,516 km, of which around 5,700 km is vulnerable to tropical cyclones and storm surges. The Bay of Bengal and Arabian Sea coastal regions are exposed to cyclones, strong winds, storm surges and coastal flooding. Coastal regions are also vulnerable to tsunamis, particularly because of their exposure to seismic activity in the Indian Ocean region.

Landslide and Avalanche Vulnerability: 

The Himalayas and Western Ghats are major landslide-prone regions because of their steep slopes, geological conditions and intense rainfall. The Himalayan region is also vulnerable to avalanches and flash floods. Deforestation, unplanned construction, road cutting and other human activities can further increase slope instability.

Human-Induced and Urban Vulnerability: 

India's disaster vulnerability is not limited to natural hazards. Rapid and unplanned urbanization, population growth, environmental degradation and inadequate infrastructure have increased the risk of urban disasters. Urban areas can face urban flooding, industrial accidents, chemical accidents and fires. Poor land-use planning and construction practices can further increase the impact of such disasters.
