Vulnerability Approaches to Impacts
VulnerabilityVulnerability describes describes the extent to which a the extent to which a system is susceptible to system is susceptible to sustaining damage from sustaining damage from climate change.climate change.
Aspects of Vulnerability
Biophysical vulnerabilityBiophysical vulnerability Social vulnerabilitySocial vulnerability
IPCC Conceptualization of Vulnerability
Vulnerability is a function of the character, Vulnerability is a function of the character, magnitude and rate of climate change and magnitude and rate of climate change and variation to which a system is exposed, its variation to which a system is exposed, its sensitivity, and its adaptive capacity.sensitivity, and its adaptive capacity.
Sensitivity
The degree to which a The degree to which a system will respond, system will respond, either positively or either positively or negatively, to a change negatively, to a change in climate.in climate.
Exposure

Adaptive Capacity
The capacity of a The capacity of a system to adjust in system to adjust in response to actual or response to actual or expected climate expected climate stimuli, their effects, or stimuli, their effects, or impacts.impacts.
IPCC conclusion:
” ”Those with the least resources have the Those with the least resources have the least capacity to adapt and are the most least capacity to adapt and are the most vulnerable.”vulnerable.”
Is Norway vulnerable to climate change?
Which regions, sectors, and social groups within Norway are most vulnerable to climate change?

A vulnerability approach can improve our understanding of socio-
economic perspectives on climate impacts and policies, and help in
identifying and targeting adaptation strategies.
