Led by the Swedish Lulea University of Technology, Green/Blue Cities aims to seize opportunities arising from future challenges to effectively manage urban storm water. This project uses an Urban Living Lab approach, bringing together citizens, practitioners, decision makers, and researchers, to jointly develop innovative solutions. The Swedish city of Kiruna will feature as a main Urban Living Lab, as Co-applicant Arjan van Timmeren, Professor of Environmental Technology & Design Faculty of Architecture at Technical University Delft (Netherlands), explains: “Kiruna offers an unique opportunity to set up the same city in a different, more ‘blue-green’ way without changing the existing structure.”
