Oslo Green City Forum 2013: Presentation by Johannes Riegler

  1. 1. Urban Megatrends and Challenges.An JPI Urban Europe Study.Johannes Rieglerjohannes.riegler@ait.ac.atOslo Green City Forum 20136th of June, 2013
  2. 2. Purpose of the Study.The Study aimed at…• … Identifying and understanding the challenges stemming frommegatrends for European Urban Areas.• … creating a differentiated perspective of challenges for urbanareas across Europe taking into account regional disparities.• … highlighting the complex connections between the challengesand megatrends .• … identifying research and innovation needs.• … generating input for the JPI UE Strategic Research andInnovation Agenda.
  3. 3. Approaching Urban Megatrends.Quantitative Analyses• Analyses of RegionalDifferences
  4. 4. Quantitative analysis of Urban Megatrends.• … for a common understanding and baseline for furtherinvestigations.• … illustrates a Europe-wide image of trends and challengesinfluencing urban areas in the coming decades.• 148 city regions were part of this analyses.• Data Sources: EUROSTAT (baseline data), IIASA (demography), UniversityParis 1 (economy), University of Edinburgh (land use), AIT (intraregionaldistribution in the urban regions)
  5. 5. Quantitative analyses of Urban Megatrends.• 148 city regions - five city region types (defined by geographical location)Data source: PLUREL project 2007-2010Population numbers: EUROSTAT; pop. distribution and morphology exploration: AIT
  6. 6. Demography: Decreasing Population in the East.Growing urban regions in the West.Figure: City regions‘ future population dynamics –2025 relative change of population since 2001 (Data:PLUREL project, IIASA, Univ. Edinburgh, AIT)Figure: City regions‘ future population dynamics –2025 relative change of population since 2001 (verticalaxe) against city size ( horizontal axe - population numbersas log-scale). (Data: PLUREL project, IIASA, AIT)2001- 2025
  7. 7. Demography: The Share of elderly (60+) increasesthroughout Europe.Figure: City regions‘ share of the 60+ age cohort 2001 and 2025 (Scenario A1) (Data: PLUREL project, EUROSTAT, IIASA, AIT)2025:
  8. 8. Economic Development: The GDP per capita shows adistinct east-west and south-north upward gradient.Figure: City regions‘ GDP per capita 2001 and 2025, Scenario A1) (Data: PLUREL project, EUROSTAT, Boitier et al., AIT)2001 2025
  9. 9. Economic Development: The GDP per capita shows adistinct east-west and south-north upward gradient.Figure: City regions‘ GDP per capita (vertical axe) against city size (horizontal axe, log-scale) - 2001 and 2025, Scenario A1), estimatedtrend lines for the sub-groups Eastern-Continental, Mediterranean, North-western (Data: PLUREL project, EUROSTAT, Boitier et al., AIT)2001 2025
  10. 10. • The increase in temperature will concentrate on Southern & EasternContinental regions & those neighbouring the Alps• No. of Heat Days and Tropic Nights will increase rapidly mainly inSouthern, and Eastern Continental regions.Climate Change.Figure: Number of heat days (days with Tmax >25°C) – averages during 30 year periods 1971-2000, 2011-2040, 2041-20701971 - 2000 2011 - 2040 2041 - 2070
  11. 11. Urban Megatrend Study: Conclusions.• The megatrends manifest differently in space and are depending onthe spatial context (Governance System, History, Planning, etc.).• Challenges accumulate in certain urban regions.• There is a mismatch between need for action and the scope of action.• Challenges deriving from one Megatrend may influence otherchallenges.• These interactions are highly dependent on local circumstances.

  14. 14. Challenges for Scandinavian Urban Areas• Economic Turbulances are expected to have relatively low in impact.– Lack of labour force.– Less regulation. Market driven development.• Climate Change mitigation: Medium Challenges.– Technology is there.– Exposure is relatively low compared to other regions.• Aging: low uncertainty.– Share of 80+ is growing significantly: new economic prosporous group.– Mild effects in urban areas.• Social Issues:– Young, Poorly educated fall out of the system (spatial and societal exclusion)– Education for migrants is key.– Energy Poverty.– Affordable Housing.– Segregation– Shrinking Solidarity.• Built Environment– Many one-person households– Low density
  15. 15. Workshop• 5 Research, Development & Innovation Areas.• Questions raised:– Reflecting on the presented challenges, what ismissing from a Norwegian point of view?– What are the most important urban challenges in thethematic RDI areas for Norwegian cities?– How should the Norwegian city of the future look likefor your group’s city image?
