  2. 01IntroductionHazards, risk drivers, and why satellite EO is uniquely suited to adaptation and resilience.
  3. 02Adaptation and ResilienceRisk as the interaction of hazard, exposure and vulnerability; the four stages of the adaptation cycle; and the resilience they build — illustrated by the Netherlands Delta Programme.
  4. 03The Role of Satellite EOThe value of EO, its role across the adaptation cycle, and EO-based indicators.
  5. 04Institutions & FrameworksCEOS, CGMS, GEO, WMO/EW4All, the Global Goal on Adaptation, NAPs, and the Sendai Framework.
