From vision to reality : A comparison of visions and real built environments regarding green structures in the Royal Seaport (English)
Abstract [sv]

Syftet med arbetet är att med hjälp av en litteraturstudie och en egen framtagen modell för bildanalys undersöka grönstruktur i visionsbilder som används i tidiga skeden av stadsbyggnadsprocessen och dess återspeglingen i verkligheten. Modellen för bildanalysen är baserad på Boverkets tankemodell för bostadsnära natur samt värdering genom ekosystemtjänster och denna tillämpas sedan på ett antal platser i Norra Djurgårdsstaden. Resultatet visar på att implementeringen av grönstruktur sker i mindre utsträckning i verkligheten än i visionsbilder. Trenden ter sig därför vara att grönstruktur bortprioriteras någonstans i processen, även om det finns ett antal undantag. Vidare förs en diskussion kring avvikelserna och deras betydelse för en hållbar stadsplanering med hjälp av intervjuer med två landskapsarkitekter.

Abstract [en]

In a world where more and more people settle into cities, the demand for sustainable urban housing grows. Today, about 60 to 80 percent of the total amount of emissions takes place in cities, and to tackle this problem along with the urbanization issue city planning needs to take all aspects of sustainable development into consideration. One important factor for a successful and prospering city has always been, and continues to be, green infrastructure.

This project is carried out with the purpose of investigating green infrastructure in vision images (used early in the city planning process) and their degree of reflection in finished projects, as well as highlighting potential deviations and connect these to consequences in social, ecological and economic aspects of sustainable city planning. This is done by implementing a visual image analysis on four places in Norra Djurgårdsstaden, based on a literature study of relevant research - largely Boverkets model for close-to-home nature and an evaluation method based on ecosystem services. For the discussion interviews were also conducted with two experts on the subject, landscaping architects, to further deepen the analysis and to make a more fair comparison of the images in the project.

The result shows a tendency where the green infrastructure in the vision images do not coincide with the photos of the actual places. Only in one of four places does the photo show a tendency for better and greener infrastructure than the vision image. This general difference could be due to green infrastructure not being prioritized over other factors in the planning process or the fact that there is little to no discussion between the architect and the entrepreneurs when the vision image is finished. Another factor that can affect this difference is that a city planning process can take years to finish, and vision images come into play in a very early stage.

With regard to ecosystem services, only two specific cases of one type of ecosystem service show better results in the photo than in the vision image. This was the factor of stormwater management. This exception from the general result of the project suggests that there may be some incentives to invest in ecosystem services that serve stormwater management due to concrete strategies, something that comes up in one of the interviews as well. The result further suggests that implementing the same type of strategies and demands with regards to other types of green infrastructure may lead to them becoming higher priorities throughout the planning process. Some type of monitoring work, which is non-existent today, is also proposed to make sure these strategies are followed correctly and to reduce the gap between vision and reality.

With respect to ecological factors the result shows a reality which contributes less to a sustainable city than what the visions suggests. Purely economically, this could feasibly affect projects in the future when new solutions must be invested in that the ecosystem services could have provided from the beginning. On the social plane, the difference between green infrastructure in vision images and reality could potentially lead to problems with trust between the general public and administrations or that employers get a different outcome of a project than what was promised. In conclusion, the dissonance between vision images and reality that the result indicates may affect all three aspects of sustainable city planning.
