Valuation of ecosystem services provided by urban greenery

Urbanization and densification of Swedish cities during the last decades has led to a decrease of greenery in our cities. Despite the importance of greenery for a good, environmentally sustainable urban living, it may easily draw the short straw when cities are densified or transportation infrastructure is rebuilt. The project will therefore study the spatial distribution of urban greenery in Gothenburg and highlight its value and ability to provide vital services in the city.

Integrating urban greenery into urban planning

Methods that make it possible to efficiently integrate urban greenery into urban planning and risk management will be developed within this project. The aim is to develop a method that will identify and provide an integrated assessment of ecosystem services provided by urban greenery. Strategies for how greenery can be used to promote sustainable urban development will also be developed

Quality of ecosystem services

The methods and strategies will be developed through assessing and evaluating the current quality of a number of ecosystem services provided by urban greenery, their development potential and examining how the ecosystem services interact. The ecosystems services that will be studied are: biodiversity, noise reduction, air soil and water management, climate regulation, recreation and well-being.

Urban greenery in Gothenburg

Seven green spaces in Gothenburg, Sweden will be used as case studies. Examples of green spaces include vegetation along rivers and roads, parks, gardens, and urban woodland.  Read more about the case study areas here (only Swedish). Gothenburg is interesting due to its pressure to densify the city and its vulnerability to climate change (floods, heavy rains, landslides and heat waves). The methods used include spatial data analysis, field measurements, modeling, questionnaires, expert judgments and multi-criteria analysis (synthesis).

Research carried out

During spring and summer 2015 we have measured air pollutants and noise in different types of green spaces in Gothenburg, our case study areas. At the same time we continued to analyze all the data that was collected in 2014, both from measurements and the questionnaire sent out to residents near our case study areas. We are very grateful for all the answers from the residents who shared knowledge, thoughts and experiences of the urban greenery. The questionnaire together with the measurements will give an increased understanding of the importance of the greenery for residents in Gothenburg and will be invaluable to the research project.

  • Yvonne Andersson-Sköld

    Associate professor at the Department of Earth Sciences, University of Gothenburg

    Has special interest in sustainability assessments including method development. In this project the aim is to assess how proposed urban greening planning strategies promotes sustainable urban development today and in a future climate based on interviews, workshops and the results from the field surveys in an iterative process.

  • Marcus Hedblom

    PhD, Researcher and Analysist at the Swedish Agricultural University, Department of Forest resource management in Umeå and Department of Ecology in Uppsala.

    Within this project he studies how the collection of biological data can support other ecosystem services that relates to e.g. well-being, noice reduction and air pollution. More specifically how the actual collection of the biological data can be used for monitoring of ecosystem services connected to the urban green.

  • Igor Knez

    Professor of psychology at the Department of Social Work and Psychology, University of Gävle

    In general, my research interests involve issues related to cognitive, emotion and environmental psychology. In this project my attention is focused on the links between the cultural ecosystem service of place-related identity and well-being, as related to urban green spaces.

  • Håkan Pleijel

    Professor in Environmental science at the Department of Biological and Environmental Sciences, University of Gothenburg

    My research focus is plant-atmosphere interactions. In the project my task is to show how urban vegetation affects the occurrence of air pollutants and the urban local climate based on measurements and a literature review. The local climate effect by vegetation is related to the cooling effect from transpiration by urban trees.

    PhD in acoustics, Division of Applied Acoustics, Chalmers University of Technology, Gothenburg

    Research interests are the development of calculation models for sound generation and propagation outdoors from differens sound sources, e g road and railway traffic, wind turbines and general sound sources. In my research I also develop alternative measures that correlate well with the perception of the human ear and/or subjective annoyance.
