Grön infrastruktur i förebyggande syfte mot värmeöar. En studie av Kalmar och Kungsbacka kommuns klimatanpassningsarbete

Detta är en Kandidat-uppsats från Göteborgs universitet / Institutionen för ekonomi och samhälle

Sammanfattning: The ongoing global climate change with its rising trends in global temperature, can be linked to the increasing frequency, intensity, duration, and extent of extreme weather fluctuation. Urban heat waves, in combination with urbanization processes which replace natural landscapes with impervious surfaces, are causing the development and manifestation of urban heat islands (UHI) in cities. The proportions of such heat islands depend both on society’s resilience, as well its adaptability. It is therefore essential to find solutions which mitigate the consequences these UHI: s yield on local climates for humans to continue living in urbanized cities in the future. The concept of green infrastructure (GI) is one prominent climate strategy in which phenomena like heat islands are attended to.The aim of this bachelor thesis is therefore to analyze and explore if the current land use structure in the conurbations of the Swedish municipalities of Kalmar and Kungsbacka can cause future UHI: s. This study also explores to which degree the concept of GI is conveyed in the present spatial planning material and strategic documents published by the urban planning offices and the County administrative boards. In addition, this thesis incorporates the experiences and knowledge of the city planners of Kalmar and Kungsbacka as well as depicting possible challenges in implementing GI. The methods used in this study are a GIS-analysis, interviews, and a document analysis.The results of the study show an affinity in both municipalities for UHI: s to form. Furthermore, it is revealed that both counties have incorporated GI in their spatial planning documents, albeit without concrete measures. A need for further development has presented itself on a municipal level, as well as performing risk-analyses to better prepare for future temperature rise and climate change.The study also shows a discernible absence of the mention and regulation of UHI: s in all spatial planning materials. The challenges that were identified regarding implementation of GI include, inter alia, the creation of design standards that are applicable on a larger scale, funding and finances, socio-economic considerations, along with the need for an increased knowledge base and interdisciplinary collaboration.There remains work to be done by the municipalities and the County administrative boards to develop guidelines and strategies to achieve set goals and visions of a sustainable city, as temperatures will keep rising and become a more prominent problem in the future.
