Sofia EskilsdotterBoard member
The best moment in my work as a practising landscape architect, is when I get to experience the actual implementation of green and blue public spaces, in full scale, in real life. Being a part of improving everyday life for a broad range of people, is truly motivating. This driving force combined with a strong passion for nature and art, has influenced me to put time and energy into the fields of knowledge that I personally find the most difficult, that is the technical and biological parts. I believe that these are the most crucial areas when it comes to implementation of our green and blue visons.
I have a long term experience in project planning for complex urban projects, previously working many years within a large architectural office and since a few years back working as an independent specialist consultant. Multifunctional planting beds for urban trees, using rock, and urban wetland parks for stormwater treatment, are some of the technical solutions that are a part of my work. During the last few years my scope has widened to also include vegetation on buildings, such as green walls and green roofs.
Part time I teach at the landscape architect programme at the Swedish University of
Agricultural Sciences in Uppsala. An important part of this work is to engage in course development, assuring that our students will be well equiped to handle the needs of the future. Subject areas that I believe will need extra attention when we adjust our pedagogical activities, are urban ecology, sustainable stormwater solutions, environmental psychology and building integrated vegetation.

Susanna Lehvävirta learned her doctoral degree in 2005, with a thesis focusing on urban forest ecology and user effects. Since then, she has run several research projects concerning urban ecology and the interrelationship between nature and man.
Her research is interdisciplinary and problem-driven. She focuses on holistic approaches to understand urban ecosystems and in order to apply research results. She combines different fields of science to understand the interlinkages between nature and the human society, and to e.g. explore values, and help develop decision making, jurisprudential perspectives etc.
She is a researcher at University of Helsinki and runs three major research programs that focus on green roofs, urban forests, and assisted migration of plants according to climate change. She has a strong background in empirical ecology but due to her interdisciplinary research has published in the fields of law, engineering, economy, recreational psychology and aesthetics also.

Bent BraskerudBoard member
Bent C. Braskerud works as a chief engineer at The City of Oslo Water and Sewerage Works. His main responsibility is preparing the city for increased stormwater due to urbanization and heavy rainfall due to climate change. Green infrastructure is an effective approach to making the city resilient to urban flooding, while increasing the quality of life. Green roofs are important to achieve these goals.
Bent was educated as an agronomist at the Norwegian University of Life Sciences. He worked as a researcher at Jordforsk (now: NIBIO) for several years constructing wetlands to mitigate diffuse agricultural pollution. The work included a PhD. His career continued as a researcher on urban hydrology at The Norwegian Water Resources and Energy Directorate (NVE), resulting in construction of experimental raingardens and green roofs, with measurement of precipitation and runoff. Bent’s work has been published in numerous scientific papers and reports.

M.Soc.Sc, doctoral student, associate leader of The Fifth Dimension – Green Roofs in Urban Areas -research program, University of Helsinki, Finnish Museum of Natural History & Urban Ecology Research Group
My field of expertise is environmental sociology and environmental social science, specifically urban questions. At the moment I am studying people’s mental images of different kinds of urban green roof solutions and testing multisensory aesthetic and restorative experiences on green roofs. I have explored expectations and experiences of private green roof owners, and studied how green roofs are adopted and realized in large construction processes. I am developing a future-oriented method for studying experiences of urban spaces in different surroundings, to be used e.g. in the context of participatory urban planning and design. My aim is to integrate user perspective into urban greening, using green roofs as model spaces. As part of Fifth Dimension -research program, I am also applying scientific knowledge in real-life construction processes in Helsinki, Finland.
The Fifth Dimension – Green Roofs in Urban Areas –research program aims to produce scientifically high-level and broadly applicable knowledge on optimal green roof solutions in Finland. Scientifically, green roofs serve as experimental model ecosystems for research and provide an opportunity for inter- and transdisciplinary research that is societally relevant. The research policy of the program includes working in close contact with the end users of scientific knowledge, such as municipal and state authorities, companies and the citizens. The main target of the program concerns the potential of green roofs to enhance urban nature and ecosystem services, as part of multifunctional urban green infrastructure. The aim of the program is to evaluate the various benefits green roofs may offer, and to develop optimal solutions and designs for green roofs that offer the best possible services for the urban residents.
