DESIGNING RESILIENCE
FOR COMMUNITIES AT RISK

RISK AND RESILIENCE
• Changing status of communities:
• Greater exposure to hazards
• Aging infrastructure
• Changing demographics
• Increasing demand for services, but declining resources
• Deepening vulnerability to extreme events
POLICY DILEMMA
• Reduce risk vs. increase resilience
• Risk: exposure to harmful events outside one’s control
• Resilience: capacity to absorb damaging event, but maintain
basic operations to support the community
• Tension between allocating scarce resources to reduce
vulnerability to risk….
• ….or developing capacity to manage risk more efficiently
KEY FACTORS THAT UNDERLIE RISK
• Insufficient monitoring of changing environment
• Heterogeneity in populations exposed to risk
• Inability to recognize threats in different arenas of
action
• Asymmetry in information processes among different
constituent groups
• Inability to mobilize collective action to counter threat
KEY FACTORS THAT UNDERLIE
RESILIENCE
• Capacity to hold and exchange information
• Flexibility to adapt to changing situation
• Commitment to a shared goal for the community
• Systematic assessment of changing state of
community
• Capacity to update information about risk and to
act on timely, valid information
BUILDING RESILIENCE
• Three basic tasks:
• Build a knowledge base of region and its exposure to risk
• Identify the parameters in the system that can and will vary
under threat, e.g.:
• Number of personnel engaged in operations
• Degree of commonality among actors in terms of training,
experience, available resources
• Number of demands placed on the system
• Identify the threshold for intervention in system to inject new
resources, material, information to enable system to adapt
HAITI FOLLOWING THE 12 JANUARY 2010
EARTHQUAKE
• Initial conditions before the earthquake:
• Extreme vulnerability in built environment: buildings, roads,
water, sanitation, communications, power systems
• Extreme vulnerability in social environment: 80%
unemployment; 55-60% illiteracy; mean life expectancy: 43
years.
• Impact of a sudden, extreme event is exacerbated by
vulnerability
• Conditions limit capacity of community for adaptation with
internal resources
• Severity of event requires external assistance
IMPACT OF EVENT, WITHOUT
RESILIENCE
•
•
•
•
Severe losses: at least 230,000 lives lost
1.5 million people homeless,
80% of the buildings in Port au Prince destroyed
Eleven out of twelve governmental ministries
collapsed, as well as the Presidential palace
Presidential Palace
Ministry of Public Works
CATASTROPHIC DAMAGE
• 80% of the schools’ infrastructure was destroyed or
damaged;
• Three of the four universities were severely
damaged,
• General Hospital, the primary medical institution in
the city collapsed

STRATEGIES FOR RECOVERY,
RECONSTRUCTION
• Reconstruction requires a “systems approach”
• System is made up of interacting, interdependent components
that adapt to changing environments
• Design a “knowledge commons” to support decisionmaking in regions exposed to risk. (Hess & Ostrom, 2007)
• “knowledge commons” includes a shared knowledge
base, but also the technical infrastructure and
organizational processes to support information search,
exchange, updates, storage, transmission
• Users of the knowledge commons contribute to
updating and revising profiles of “status of the
community” in dynamic environments.
STRATEGIES FOR RECONSTRUCTION
• Characteristics of a knowledge commons:
• Interdisciplinary:
• technical, organizational, cultural content
.
• Interjurisdictional:
• International, national, state/provincial, local
• Intersectoral:
• Public, private, nonprofit organizations as participating users
• Scalable in function:
• System is anchored at local level where first action occurs,
• but scales rapidly to wider arenas as dynamics of interaction shift
among participants
CONCLUSIONS
• Lack of local knowledge exacerbates disaster risk
• Design and development of a knowledge
commons reduces disaster risk
• Information technology, carefully designed and
implemented, facilitates information search,
exchange, and organizational learning.
• Powerful resource in process available to a
community exposed to long term risk is the capacity
of its people to learn
