Vulnerability is an essential element for defining disaster impacts and its threat to people. How and in what ways can vulnerability to disasters be characterized? Discuss different types of vulnerability with reference to disasters.
Approach · directive: “how / discuss”
What it asks · Define vulnerability, show how it is characterised (exposure, susceptibility, coping capacity) and discuss its types (physical, social, economic, environmental, institutional) with disaster examples.
It asks 2 things — answer each
- How vulnerability to disasters is characterised: exposure, susceptibility and coping capacity
- Discuss the types of vulnerability (physical, social, economic, environmental, institutional) with disaster examples

Model answer· 225words · Minimalist IAS
The 1999 super cyclone killed about 10,000 people in Odisha; Cyclone Fani in 2019 killed one (MHA). The hazard was similar, the vulnerability was not. UNDRR defines it by the physical, social, economic and environmental conditions that raise susceptibility to a hazard.
How vulnerability to disasters is characterised
- Risk equation: risk rises with hazard, exposure and vulnerability, and falls with coping capacity.
- Three lenses: exposure (what sits in harm's way), susceptibility (housing, health, income) and resilience (assets, insurance, institutions).
- India's profile: 58.6% of landmass earthquake-prone, 12% flood-prone, 5,700 of 7,516 km of coast cyclone-prone, 68% of cultivable area drought-prone (NIDM).
Types of vulnerability with reference to disasters
Vulnerability: physical; social; economic; environmental; institutional
- Physical: weak masonry, homes on floodplains, coasts, slopes and seismic zones; mapped in BMTPC's Vulnerability Atlas of India.
- Social: poverty, gender, age, disability, caste and low awareness; women, children, the elderly and the disabled suffer most.
- Economic: one rainfed crop or one fishing boat, with no savings or insurance to recover.
- Environmental: lost mangroves, wetlands and forests that once absorbed surges, floods and landslides.
- Institutional and attitudinal: weak early warning, lax building codes and fatalism; Odisha's shelters, drills and IMD warnings show these can be cut sharply.
Hazards cannot be abolished, but vulnerability can: the Sendai Framework (2015-2030) seeks the substantial reduction of disaster risk and losses in lives, livelihoods and health.
