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.
The question has 2 parts — 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
Open with · The same cyclone or earthquake harms people unequally, and vulnerability is what explains the difference between a hazard and a disaster.
Cover
- Meaning: vulnerability is how likely people, property and systems are to be harmed by a hazard; risk depends on hazard, exposure, vulnerability and coping capacity.
- Characterise it by exposure (location), susceptibility (construction, health, income) and resilience (ability to cope and recover); the same hazard harms groups unequally.
- Physical: weak buildings, unsafe sites on floodplains, coasts, slopes and seismic zones, fragile lifelines; mapped in the BMTPC Vulnerability Atlas of India.
- Social: poverty, gender, age, disability, caste and marginalisation, low awareness; women, children, the elderly and the disabled are hit hardest.
- Economic and environmental: dependence on farming or fishing, no savings or insurance; degraded forests, wetlands and mangroves that once buffered floods, slides and surges.
- Institutional and attitudinal: weak early warning, code enforcement and preparedness, plus fatalism; Odisha's cyclone response from 1999 to Phailin shows vulnerability can be reduced.
Close with · Unlike the hazard, vulnerability can be reduced through safer construction, land-use planning, secure livelihoods, awareness and inclusive preparedness, which is the core of disaster risk reduction.

- UNDRR's official definition ties vulnerability to physical, social, economic and environmental factors, a ready framework for classifying its types. Terminology on Disaster Risk Reduction: Vulnerability, UN Office for Disaster Risk Reduction (UNDRR) ↗“The conditions determined by physical, social, economic and environmental factors or processes which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards.”

The same cyclone kills in one place and only disrupts in another. Vulnerability explains the gap: UNDRR defines it through the physical, social, economic and environmental factors that make people or assets susceptible to a hazard.
Characterising vulnerability
- Risk rises with hazard, exposure and vulnerability and falls with coping capacity; vulnerability is read through exposure (location), susceptibility (housing, health, income) and resilience (assets, insurance, institutions), and it varies within one village.
Types of vulnerability
- Physical: weak masonry, houses on floodplains, coasts, steep slopes and seismic zones, fragile lifelines; 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: dependence on one livelihood such as rainfed farming or fishing, with no savings or insurance.
- Environmental: loss of forests, wetlands and mangroves that once absorbed floods, slides and storm surges.
- Institutional and attitudinal: weak early warning, lax building-code enforcement, fatalism; Odisha's journey from the 1999 super cyclone to Phailin (2013) shows these can be cut sharply.
Unlike the hazard, vulnerability can be reduced: safer construction, land-use planning, secure livelihoods, awareness and inclusive preparedness are the core of disaster risk reduction.
