Vulnerability, Resilience, & Adaptation: Societal
Causes and Responses
Elizabeth L. Malone

CRCES Workshop: Societal Impacts of Decadal Climate Variability in
the United States
26-28 April 2007
Will better information—
i.e., predictions about climate variability and change
and their impacts—
help societies build resilience and adaptive
capacity?
Answer: Not necessarily, unless people see how
such information relates to their lives and their
future.
2
Rationale for studying vulnerability,
resilience, and adaptation
These connect climate with societal issues, such as development
and well-being  salience.
By assessing current vulnerability, resilience, and adaptive capacity,
we gain insight into current dependence on climate and can extend
that insight to climate change. E.g., current lack of adaptation to
current climate may mean less resilience/more vulnerability in the
future.
Once the climate-society relationship begins to be defined,
information about future climate becomes more important.
3
Why the Vulnerability-Resilience
Indicators Model (VRIM)?
Changes the focus from physical impacts to meaningful societal
consequences
Brings together social, economic, and environmental factors
Summarizes information via quantitative indicators
Scenario-driven, i.e., allows different future conditions to be
explored
Allows comparisons (unlike most case studies) while preserving
transparency (in sources of the “scores”).

Important Concepts
Vulnerability: capacity to be harmed; composite of sensitivity,
adaptability, and exposure
Resilience: the ability to cope with or recover from exposure or
shocks
Sensitivity: the degree to which changes and/or variability in climate
lead to changes in system attributes
Adaptation: adjustments in anticipation of or in response to climate
change and/or variability
Adaptive capacity: the ability to adjust to new conditions
Exposure: climate stimuli that affect a system or region

The states with the highest and lowest resilience are similar in
ecosystem resilience and close in environmental capacity, but
differ greatly in settlement security, food security, human health,
human resources and economic capacity

Assessing resilience and adaptive capacity
reveals policy spaces for building both
Although geographic and climatic conditions are important, even
more important are the social-ecological systems in a region.
Results lead to the next set of questions about policy priorities in an
area – but clearly different places have different policy needs.
The VRIM country-level adaptive capacity results have been
combined with projected climate change from the COSMIC model
to show that impacts may well outrun adaptive capacity in most
places during this century (Yohe et al. 2006).
