Eva Streberová and Tatiana Kluvánková, Ecosystem Services to Govern Urban Commons

  1. 1. Ecosystem services to govern urban commons Streberová, E. 1,2, Kluvánková, T. 1,2, 1 SPECTRA, Centre of Excellence EU 2 Institute of Forest Ecology at Slovak Academy of Sciences 3 Institute of Management at Slovak University of Technology
  2. 2. Presentation outline 1. CC and urban areas 2. Relevance of green infrastructure 3. Urban commons in Bratislava, Slovakia 4. Experimenting with urban commons
  3. 3. Climate change and vulnerability of cities Urbanisation in Europe: - today 72% , by 2020 80 %, 2100 90 % or more - aging population, - economic capital ↔ production of greenhouse gases, Urbanization + CC + socio-economic trends → risks for urban population: UHI (urban heat island), water scarcity, floods, droughts and heat waves extreme weather events
  4. 4. Relevance of green infrastructure in adaptation to CC Fulfils the needs of a variety of stakeholder groups and policy aims (DG Environment, 2012): - biodiversity conservation (ecological networks) - ecosystem services - mitigation of climate change related impacts (and also many other benefits and goods) Sustainable drainage Systems (Sweden) Rain gardens (UK) Green roofs and walls (Japan, France) Photos:internet
  5. 5. Urban GI & Ecosystem service provision (Demuzere et al., 2014) Physical benefits: • CO2 sequestration, • flood protection, • improved water abudance and quality, • air quality and temperature regulation, • food production • reduced energy use, Psychological and social benefits: • Health and restorative benefits, • Aesthetic appreciation • Inspiration • Education • Recreation & leisure Photo:
  6. 6. What is green infrastructure: „Network of green spaces in which and through which natural functions and processes are sustained.“ (EC, 2013) In urban environment: „A hybrid infrastructure of green spaces (and blue spaces) and build systems.“ (Demuzzere et al., 2014) Urban gardening (Slovakia), Street trees Court-yards (Slovakia) Green Bike paths (Slovakia), River revitalisation, Parks and ponds
  7. 7. Management effectiveness of urban green spaces – urban commons (new) Urban commons are publicly shared resources that have been reconceptualized as commons, mostly human-constructed, parts of urban environment (Hess 2008, Maco, Kluvánková, in review). Photo:,,,,, Gated-communities (Herrod, 2011) Parks and multipurpose public spaces (Kassa, 2008 , Poklembová, 2013) Street trees (Steed, Fischer, 2011), Court yards (Maco, 2015) Community gardens (Maco, 2015)
  8. 8. Climate change in Bratislava Vulnerability: increase in average citizen age from 44,6 yrs in 2011 to 47,8 in 2025 in Bratislava old town greyfication of population in Bratislava – by 2025 rise of number of retired citizens 9% Heat exposure: heat islands due to accumulation of radiance during day by aritifical surfaces and urbanistic structures in the city centre, lack of green infrastructre in city center, expected rise of average annual temperature in Western Slovakia by 0,4 °C by 2030 any by 0,9 °C by 2075. Behavioural exposure: outdoor activities in city centre , playgrounds, kindergartens, schoolyards, etc.
  9. 9. Share of citizens over 75 yrs of age in comparison to total population in Bratislava [%] (Hudeková, 2009) Thermovision images ( in corridors) over Bratislava city centre during a hot summer day (Source: REC Slovensko, Fotomap, s.r.o, 2007)
  10. 10. Management of urban commons: public and semi- public green spaces in Bratislava, Slovakia • Public and Semi-public spaces – providing common, public and private goods • Production services (individual & collective benefits) – urban agriculture, urban farming • Local climate regulation and cultural ecosystem services (collective benefits): - cooling effects (evapotranspiration), shading, reducing heating/cooling costs, air filtration, noise reduction, carbon sequestration (1800 € annually) - recreation and leisure activities, etc. (617 193,23 € - 2,6 mil. €) Horský park Courtyard Legiodomy Courtyard Slavia Community garden Photos: Authors
  11. 11. Photos: Experimenting with Commons „You can discover more about a person in an hour of play than in a year of conversation.“ (Plato) Analyse and predict individual and group behavior under the controlled situation: social dilemma under the complexity and uncertainty. Test novel instruments and decision tools in real world situation (simplification of real life situations to zoom in on specific decision problem)
  12. 12. Role Board Games • Interactive agent based models (field experiment + role game) • Repeatibility under the controlled conditions & time frame to increase validity of experiments in real situation (Barretau, 2001, Janssen et al., 2010) • Learning aspect: Experience gained in playing roles foreign to one´s own interest may provide insights hard to obtain in any other manner“ (Shubik, 1975) • Dynamic modelling: Feedback loops – player feedback – adjusting the simulation model & game rules • Test the sensitivity of the consequences of given set of collective rules for management of an ecosystem, with respect to a set of assumptions on individual behaviours” (Barreteau, 2001).
  13. 13. The „Green city“ role board game • Designed on Cardenas, Janssen and Bousquet (2008) new generation of field experiments with the commons • Communication and resource dynamics Developed furter at VEEL: • Player roles : 5 players :2 politicians, developer, 2 citizens • Social dilema: grey/ greeen infrastructure • Resource degradation: the fewer green spaces, the greater the urban heat island (achieve minimum of green to grey ration 2:1) • Game treatments: non-cooperative, cooperative with communication (crafting own rules) 10 rounds
  14. 14. The „Green city“ role board game Further steps: • Stakeholder involvement & follow up survey • Player (stakeholder) feedback - whether the model's assumptions match the stakeholders´own representation of the system dynamics and provide stakeholders with a large enough range of possible actions/competencies
