Simulating Future Vulnerability
and Adaptive CapacityPerspectives from projects on wildfire
and climate change
The FIRECLIM Project Simulate how various factors interact to
influence future wildfire risk in the Flathead County WUI
Actions and outputs are simulated at small scales and aggregated to different levels
Uncertainty and Action Positing “alternative futures” to explore
uncertain future impacts… Climate change Wildfire intensity Growth and development rates
…and potential human behaviors/actions
Forest treatments Land use planning regulations Homeowner mitigations
Simulating Influences Three primary sub-models
• Land use change model (RECID2)
• Climate, fire and vegetation models (Fire-BGCv2/FSIM)
• Agent-Based Model (ABM)
Measuring Vulnerabilities Risk measures account for both the
expected losses and expected benefits of wildfires
“Risk” varies among the three agents • Expected residential losses from wildfire
(E[RLW])• Historical range of variability (HRV)• Costs to implement new regulations,
mitigations or forest management• Commercial timber losses
Simulating Adaptive Actions Local agents make iterative management
decisions that influence wildfire risk in WUI, such as subdivision regulations, building materials, fuels treatment, etc.
Data collected about existing management actions, change over time
A Simplified Illustration
Adaptive Capacity and Adaptive Actions (ABM)
Three types of human decision makers or agents acting at different scales:
• Land and wildland fire management agencies (6)
• Community and regional planners (1)• Homeowners/residents (20,000)
But how to integrate adaptive capacity?
Assessing the “Intangibles” Characteristics that
facilitate future potential for adaptation
Focus groups (3) with local key informants
Ratings become weighted consideration in ABM decision rules
Decision rules use probability cutoffs or multi-criterion decision making methods
Building Better Assessments Systematically documenting the outcomes
of interacting factors
Integrating dynamic simulations and contextual approaches
Building better data, especially for the “intangibles”
The line between flexibility and vagueness
Operating at scales of influence
