Determinants of Risk: Exposure and VulnerabilityChapter 2climate change can be strengthened by including storylines of changing vulnerability and exposure under differentdevelopment pathways. Appropriate attention to the temporal and spatial dynamics of vulnerability and exposure isparticularly important given that the design and implementation of adaptation and risk management strategies andpolicies can reduce risk in the short term, but may increase vulnerability and exposure over the longer term. Forinstance, dike systems can reduce hazard exposure by offering immediate protection, but also encourage settlementpatterns that may increase risk in the long term. [2.4.2.1, 2.5.4.2, 2.6.2]Vulnerability reduction is a core common element of adaptation and disaster risk management (highconfidence). Vulnerability reduction thus constitutes an important common ground between the two areas of policyand practice. [2.2, 2.3]68
