In this lecture
- Define sensitivity separately from exposure
- Match each input to an available data source
- Avoid double-counting between inputs
Exposure is a location question
Exposure asks only where people, assets and systems sit relative to the hazard - a school on a flood plain is exposed whether or not it ever floods. Confusing exposure with vulnerability is the most common error in a first assessment, and it inflates the apparent risk of well-protected places while hiding the real one.
Sensitivity is a condition, not a location
Two schools on the same flood plain are not equally sensitive: one built on stilts with a raised generator room absorbs a flood the other cannot. Sensitivity records the physical and social condition that decides how much a given exposure actually hurts, and it is normally the hardest of the three inputs to find good data for.
