Title: A first draft of the study of the concept of polycentrism


1
A first draft of the study of the concept of
polycentrism
  • Laila Kule, consultant for Vidzeme Development
    Agency

2
The concept of polycentricity
  • Polycentrism is both an analytical concept and a
    policy option, a widely used spatial development
    policy solution at European, national and
    regional levels.
  • Towns and cities - keystones of polycentric
    development.
  • An alternative solution to the urban
    agglomeration process
  • Development of a balanced and polycentric urban
    system first time mentioned in 1994 in EU
    Ministers Leipzig Document
  • European Spatial Development Perspective (ESDP,
    1999) adopted the principle of polycentric and
    balanced spatial development within the EU
  • European Spatial Development Observatory Network
    (ESPON, 2005) study on polycentricity

3
Challenges to polycentric territorial structures
  • Spatial integration
  • Sustainable development
  • Territorial equity

4
Polycentricity and sustainability
  • Guiding Principles for Sustainable Spatial
    Development of the European Continent (2002) by
    contributing to the lowering of environmental
    pressures and social tension and stabilising
    democratic structures thus contributes to the
    sustainable development.
  • The Interim Territorial Cohesion Report (2004) of
    the EU - polycentric urban systems are more
    sustainable and more equitable than either
    mono-centric urban systems or dispersed small
    settlements.

5
Polycentricity and sustainability
  • There is no conflict between sustainability and
    polycentrism revealed in the European spatial
    policy documents.
  • In opposite, there is an emphasis that both
    concepts compliment each other.
  • There can be a certain conflict between both
    concepts as polycentricity or decentralised
    concentration requires better links and more
    intensive communication (including transport)
    between urban centres involved.
  • In thus the polycentricity approach has to be
    promoted only by coupling it with the development
    of sustainable transport networks.

6
The concept of polycentricity
  • Polycentricity is measured by identifying three
    dimensions (ESPON, 2005)
  • the size or importance of cities (population,
    economic activity),
  • their distribution in space or location, and
  • the spatial interactions or connections between
    cities and towns (including accessibility that
    determines the relative locational advantage).

7
Measures to reach polycentric development
  • Specialisation
  • the sharing of tasks and economic specialization,
    based on potential, distinctive features,
    qualities and opportunities in a region, linked
    with regional identity and the branding of urban
    and regional identities.
  • Complementarity
  • Morphological, hierarchy of urban areas (nodes
    and centres).
  • Relational, based on the networks and the
    orientation of flows and cooperation between
    urban areas at different scales

8
Measures to reach polycentric development
Complementarity and Integration
9
Types of integration between the hierarchy of
urban areas and oriented or multidirectional flows
  • 1) Integrated mono-centrism - a highly
    hierarchical urban pattern, combined with
    strongly oriented flows.
  • 2) Emerging (out-coming) polycentricity - strong
    hierarchy and multidirectional flows.
  • 3) Integrated polycentricity - a weak urban
    hierarchy associated with multidirectional
    relations.
  • 4) Metropolitan polycentricity - a weak urban
    hierarchy with strongly orientated relations.

10
Complementarity
  • Institutional or political polycentricity, based
    on voluntary cooperation (complementary with
    regard to urban functions).
  • Structural polycentricity, related to the
    organisation of a territory i.e. to its spatial
    patterns, through urban networking from
    migrations (students, active population,
    commuters) transport, financial and information
    flows.

11
Three geographic levels
  • Macro level (European/global) - the dichotomy
    between the Pentagon and the rest of Europe can
    be used as an indicator.
  • Meso level (national/transnational/
    cross-border/interregional level) - the relation
    between regions, that are functional urban areas
    with national profile, and other regions can been
    used as an indicator.
  • Micro level (regional/local) - the relations
    between different parts of a region are crucial.

12
Macro level (European/global)
  • International accessibility
  • Presence of enterprises headquarters and
    international institutions
  • Concentration of decision power, and
  • Integration with global markets
  • Removal of institutional and economic exchange
    barriers/ discontinuities
  • Equal economic structures
  • Levels of competitiveness
  • Absence of missing links of infrastructures
    (transport etc).

13
Meso level (national/transnational/
cross-border/interregional level)
  • The relation between regions, that are functional
    urban areas with national profile (capital cities
    and other national centres), and other regions.
  • Complementary and interdependent networks of
    towns.
  • Economic performance and services through
    clusters/networks of neighbouring cities.
  • Coordinated national policies particularly across
    borders.
  • Regional development policies.
  • In mono-centric countries, a focus on the second
    tier of cities.

14
Micro level (regional/local)
  • The relations between different parts of a region
  • The move from one or two dominant regional
    centres to several small and medium sized centres
    providing regional services, through urban
    strategic alliances and rural-urban partnerships.

15
Conceptual strategies to enhance polycentricity
  • Complementarity
  • Partnership
  • Governance
  • Coordination
  • Contract
  • Coherence
  • Devolution (the delegation of authority)

16
Baltic Sea Region settlement system and
polycentricity
  • VASAB 2010 (1994)
  • A competitive system of cities with international
    importance
  • A network of national and regional cities with
    good links to the hinterland ensuring spatial
    cohesion, the concept of decentralised
    concentration
  • VASAB 2010 Plus Spatial Development Action
    Programme (2001)
  • the key theme - the co-operation of urban regions
  • to raise the competitiveness of urban regions at
    three levels and thus to enhance a polycentric
    urban system
  • powerful metropolitan regions at the
    international scale
  • less dynamic major cities are promoted
  • medium-sized and not very diversified secondary
    cities as future growth engines for rural regions
    lagging behind are strengthened,
  • specialisation for secondary urban regions using
    existing tacit knowledge (competencies based on
    local production traditions) are promoted
  • to overcome a size problem the regional/ local
    clusters and functional commuting regions are
    promoted
  • networking between cities.

17
Baltic Tangent area and polycentrism
  • Baltic Tangent (BT) area consists from many
    national, regional, cross-border, interregional
    and local spatial levels and respective urban and
    transport networks to be analysed.
  • In each of these levels there are specific
    targets defined. In order to measure
    polycentricity different indicators have to be
    used.
  • On European scale BT area has to be analysed as
    one territory in comparison with the
    Pentagon, including BT area accessibility and
    links with Pentagon area and other major
    metropolitan areas in Europe.
  • European, national and regional spatial policy
    documents and particular geographical and
    historical factors and patterns have to be taken
    account.
