Risk, vulnerability, resilience

• “Risk” designs here the potential of shocks and stresses to affect, in different ways, the state of systems, communities, households or individuals. Probability, severity, economic scale, time scales and direct and indirect y, y, ,costs should be taken into account.

• “Vulnerability” is the propensity or predisposition to be adversely affectedVulnerability is the propensity or predisposition to be adversely affected (IPCC SREX 2011).

• “Resilience” is the ability of a system and its component parts to anticipate• “Resilience” is the ability of a system and its component parts to anticipate, absorb, accommodate or recover from the effects of a hazardous event (IPCC SREX 2011)

• “Adaptive capacity” is the capacity of a system to adapt in order to be less• Adaptive capacity is the capacity of a system to adapt in order to be less vulnerable. In fact it has two dimensions: adaptive capacity to shocks (coping ability) and adaptive capacity to change.

Systems

• Systems can be delineated according to various perspectives, including expected functions:environmental, economic or social, political and institutional.

• These perspectives are linked < sustainability.

S i diff i h • Systems in different perspectives share components.

S t b b dd d i t th • Systems can be embedded into one another, meaning that one system can be a component of a major system

a major system.

Resilience

Resilience: seed systems increase adaptive capacity

Building resilience: through timeBuilding resilience: through time

• Build adaptive capacity not only to existing risks but also to changes, in an evolving context.

• Build adaptive capacity at the same time as shocks occur: – ex-ante– during the shock– ex-post strategies to build resilienceg

Comprehensive strategies to build resilience to build resilience

in a context of climate change

• Reduce, or take account of amplification effects between risks

• Organize compensation Identify/understand all the risks,

vulnerabilities, systems, dimensions, tools and their targets, and how CC act on them is necessary prior to integration in a them, is necessary prior to integration in a comprehensive approach towards resilienceresilience.
