I.1. MAIN CONCEPTS

Resilience

sometimes seen as a metaphor(Pendall et al., 2008) or a general framework

(Folke, 2006; Ahern, 2011), it should also be a tool for integrated planning of

complex spatial systems such as cities and their polarized areas

Spatial resilience

refers to the relation between spatial

variationof certain relevant variables inside

and outside the system of interest and the

resilienceof that system across multiplespatial and temporal scales (Cumming, 2011)

Spatial resilience capacity

Theoretical functional urban areas

(metropolitan areas in broad sense)

the differentiated and discriminatory competence of territories to

respond, recover, cope, adapt and even develop when facing an

unexpected, sudden perturbation or stressor.

Metropolitan regions

Resilience capacityResilience capacity

not focused on a certain disaster, but on the

general ability to resist shocks as some () [units]

are structurally more preparedthan others, and

have greater capacity to bounce back in the wakeof a stress (Kathryn Foster, Dir., UB Regional

Institute).

I.2. FRAMEWORK

A harmonious relation between the city and the polarized territory reduces

spatial disparities and increases resilience capacity.

O1To test an integrated spatial resilience capacity index (SRCI) applicable to

Romanian realities by adapting the existing methodologies

II. OBJECTIVES AND METHODOLOGYII.1. OBJECTIVES

O2To assess the spatial similarities and the disparities at different scales in

order to better understand both the capacity of studied units to adapt and their

ability to become poles of regional stability and development

II. OBJECTIVES AND METHODOLOGY

II.2. METHODOLOGY

A. Delimitation of study areas:

>50000 inhabitants (at least once in their recent history) + spatial equity principle;

a road distance of max. 20 km (from the edge of the chore-city) allowing close socio-

economic relations (commuting, daily services, ex-urban activities of the city).

B. Index construction

12 indicators (aggregated from local level to metropolitanlevel) scaled by using Min-

Max rescaling scheme to create a homogenous dataset;

Principal component analysis for weighting the indicators and grouping them in three

categories; some initial indicators (environmental) eliminated (no relevance for the

model as hardly correlated to any other indicator);

Final Z Scores of the three aggregated indicators (for each category) and of the final

index -spatial resilience capacity index (SRCI). A correlation matrix was obtained in

order to study their relation; Mapping the SRCI in order to compare:

functional urban areas (metropolitan areas);

metropolitan areas and non-metropolitan areas;

urban metropolitan areas/rural metropolitan areas/urban non-metropolitan

areas/rural non-metropolitan areas.

IV. CONCLUSIONS

SRCI- an adaptation of RCI to Romanian realities - spatially integrates the main urban

poles to the surrounding area (hinterland) by taking into account the local, regionaland national processes and outcomes that enforce or diminish resilience;

a peripheral country whose segregated territory shows a clear western orientation,

but also the lack of coherent regional strategies which decreases the overall

resilience capacity;

needed integration of resilience within spatial planning policies taking into account

the context at local (urban-rural systems) and regional scale (relations between cities,

fractures or complementarily between metropolitan and non-metropolitan areas);

metropolitan areas that became regional development poles benefit from

investments, innovation, diversified economy, finances, high skilled human

resources, infrastructure etc. and adapt easier to present globalized challenges;


13/13

the direct influence of a city is not a guarantee for a clean environment, a sound

community, a healthy economic development or a high resilience capacity;

a high resilience capacity does not mean that an urban region/metropolitan area will

successfully manage any crises it faces, but it is a premise that it might.

Future developments

the reiteration of SRCI: revising the 12 indicators, introducing others:

a better integrationof indicators capturing environmental or geographic factors

and governance is needed in order to better cover these dimensions of spatial

resilience;

the assessment of long term regional trends in resilience capacity of urban functional

areas.
