THROUGH COLLABORATIVE URBAN
SERVICES MANAGEMENT
Marie Toubin Session: Natural Hazard Resilient Cities

2. Presentation plan
2

 An operational translation for local authorities
 The role and importance of urban services
 Methodology
 An auto-diagnosis tool to identify dependencies
 Analysis of interdependencies between urban services
 A typology requiring to refine the approach
 Perspectives
 Territorial analysis of networks resilience
 Assessment of city’s resilience
Global risk Forum Davos – 28/08/2012 Marie Toubin

3. What is resilience?
3  Context and objectives
 The resilience approach
 Systemic approach
 Multi-scalar considerations
 New abilities: adaptation,
absorption, learning
Global risk Forum Davos – 28/08/2012 Marie Toubin

4. Can the city be considered as a system ?
4  Context and objectives
 The resilience approach
 Urban sub-systems
 Urban functions: shelter,
economy, culture, …
 Integrated assessment:
interactions, spatial and
temporal scales
Global risk Forum Davos – 28/08/2012 Marie Toubin

5. Urban resilience
5  Context and objectives
 The resilience approach
Global risk Forum Davos – 28/08/2012 Marie Toubin

6. Urban functions depend on networks
6  Context and objectives
 An operational translation for local authorities
Global risk Forum Davos – 28/08/2012 Marie Toubin

7. Urban functions depend on networks
7  Context and objectives
 An operational translation for local authorities
 Improve urban resilience by
improving urban services’
resilience
 Provide basic needs to the
population
 Enable the continuity of
economic activity
 Facilitate recovery
 A levier of action for local
authorities
 Involvement of all territory
stakeholders
Global risk Forum Davos – 28/08/2012 Marie Toubin

8. Urban services specificities
8  Context and objectives
 The role and importance of urban services
 Socio-technical objects
 Managers with social and economical objectives
 Technical complexity and geographical extension
 Necessary before, during and after a disaster
 Preparation: vulnerability reduction, human and material resources pre-
positioning
 Reaction: avoiding additional risks, safety and emergency actions
 Recovery: basic needs, reconstruction
 With a resilient management?
 Public and private societies
 Sector-based management
 Numerous and complex interdependencies
Global risk Forum Davos – 28/08/2012 Marie Toubin

9. Urban services specificities
9  Context and objectives
 The role and importance of urban services
Global risk Forum Davos – 28/08/2012 Marie Toubin

10. Assess the functioning of urban
services under disturbances
10  Methodology
 An auto-diagnosis tool
 Input-output description at a macroscopic level
 Avoid safety and competitiveness issues
 Overcome lack of knowledge
 Criticality assessment:
 Capacity of autonomy?
 Impacts of disruption?
Global risk Forum Davos – 28/08/2012 Marie Toubin

11. A system of systems
11  Methodology
 Analysis of interdependencies
 Matrix construction and graph analysis
Global risk Forum Davos – 28/08/2012 Marie Toubin

12. Typology of interdependencies
12  Methodology
 Analysis of interdependencies
 Outcome of a collaborative workshop
Global risk Forum Davos – 28/08/2012 Marie Toubin

13. Discussion about difficulties and
solutions
13  Methodology
 Need for refining the description
 Differenciate difficulties and solutions following the system
 Punctual/integrated, protection/reorganisation,
strenghtening/alternatives
Global risk Forum Davos – 28/08/2012 Marie Toubin

14. Identify components and
interdependencies within a territory
14  Perspectives
 Territorial analysis of networks resilience
 Locate critical components of each system
 Assess their intrinsic vulnerability (exposure to risks, internal
resources and functioning)
 Assess their dependencies to external resources (before, during and
after a crisis)
 Identify their strategies
 Resilient measures
 Actions to be realized (location, time, means)
 Compare with disturbance scenarios:
 Failures in resource supply
 Changes in the risk scenario (duration, intensity)
Global risk Forum Davos – 28/08/2012 Marie Toubin

15. Match the needs of urban issues with
services impacts
15  Perspectives
 Assessment of city’s resilience
 A service disruption as a
new risk for the territory
 Impacts for economic,
political and social issues
Global risk Forum Davos – 28/08/2012 Marie Toubin

16. The RESILIS Project
16  Perspectives
 Assessment of city’s resilience
 Articulate the urban services analysis within an integrated
approach
Technical resilience
•Technical networks,
buildings
•Resistance, absorption,
redundancy
Organizational
Cultural resilience resilience
•Decision-makers, •Urban services,
populations, managers administrations,
•Preparation, autonomy, activities
adaptation •Anticipation,
planification, flexibility
