UPSC Mains 2019 GS3 Q8 — Disaster Management

• The conceptual relationship between Hazard, Risk, and Vulnerability (Risk = Hazard x Vulnerability).
• The indicators or parameters used to characterize vulnerability in a population.
• Categorization of vulnerability into Physical, Socio-Economic, Environmental, and Institutional types.
• The specific ways vulnerability exacerbates disaster impacts beyond the event itself.

• Confusing 'Vulnerability' with 'Hazard' or 'Disaster' (e.g., describing a flood instead of why people are susceptible to it).
• Focusing only on physical/structural vulnerability (buildings) while ignoring social aspects like gender, age, or poverty.
• Providing a generic list of disasters instead of analyzing the underlying factors that make a community vulnerable.
• Neglecting the 'Impact' aspect mentioned in the question—failing to link vulnerability to the scale of loss.

Spend approximately 30 words on the introduction defining vulnerability as the 'propensity to be adversely affected'. Devote 50 words to characterizing vulnerability through specific indicators. Allocate the remaining 70 words to discussing the four main types (Physical, Social, Economic, Environmental) with brief examples like kucha houses or lack of early warning systems.
