In this lecture
- Separate hazard, exposure and vulnerability
- Explain why the same hazard produces different outcomes
- Place vulnerability assessment inside the wider risk framework
Three words, one equation
Risk is not a hazard, and a hazard is not a threat until something is exposed to it and unable to absorb it. This opening lecture builds the hazard-exposure-vulnerability model climate risk assessments use, and follows one cyclone through all three terms to show why the same storm produces a fatality in one town and a power cut in the next.
Vulnerability is the part policy can change fastest
A department cannot move a coastline or cancel a monsoon, but it can put a title deed, a second income or an early-warning system in front of a household before the next event arrives. Hazard and exposure are largely given; vulnerability is where an assessment earns its budget, because it is the term most open to intervention.
