Green structure enables ecosystem services
In connection with the C/O City research project, the Green Space Index (GSI) planning tool was developed and tested in Kolkajen and Sdra Vrtan. The results show the importance of including the ecosystem perspective and applying the GSI at an early stage of the process, in order to influence and achieve a joint vision for the planning. The GSI also makes it easier to communicate the significance of these issues. See page 60 in the Monitoring Report.
Green Space Index
The Green Space Index (GSI) is a tool for calculating eco-efficient space, meaning space that makes a positive contribution to its own ecosystems and local climate, and to the social values associated with greenery and/or water. The GSI rewards a range of ecosystem services. Experience shows the importance of applying the GSI in early stages and integrating the tool into the architecture.
Green courtyards create quality of life
The block is used to strengthen the areas green structure. The GSI for property level ensures that the block is developed for multiple purposes, so that the same space can be used for several functions simultaneously. Green courtyards and roofs hold stormwater runoff, strengthen biodiversity and create recreational values.
Ecosystem services are the benefits that humans gain from the natural environment. Urban nature is not only decoration for the Citys residents, it also serves a wide range of critical functions. By planning well, a green space can serve multiple purposes simultaneously enhance well-being, provide food for insects, manage and purify the increasing rainwater and reduce the Citys noise.
Stockholm Royal Seaport as a dispersal zone
The Royal National City Park has significant ecological values with a rich array of plants and animals, and cultural heritage stocks of sensitive species. The northern section of Stockholm Royal Seaport is part of a green structure providing a dispersal network for oak-dependent species and amphibians. By preserving and promoting ecosystems for amphibians and oak-dependent animals, for example by building a frog tunnel and planting oak trees, strengthens the habitats. These initiatives are important for securing the dispersal zone.

Early planning secures the green structure
In the planning process for Loudden, a number of feasibility studies were carried out to determine the need for strengthening the green structure, and dispersal corridors to southern Djurgrden. These included an ecology study, which discovered the existence of a large protected salamander species in the area. See page 61 in the Monitoring Report.
The most innovative element of Stockholm Royal Seaports urban greenery is how rainwater is managed. On the streets, all water is led through special drains to plantations with biochar-amended soil. The Green Space Index requirements for property developers are also innovative because they generate multifunctional green spaces on development sites.
But what I am most proud of is the number of parks and playgrounds in the area that are available for play, recreation and exercise, with places to soak up the sunshine and enjoy the flowering gardens and park greenery. We also have a strong link between new and old Hjorthagen, and two new bridges have made it easier to visit the Royal National City Park. The fact that everything is so well-built and attractively designed also makes me very pleased.
