زیرساخت های سبز شهری در اروپا: آیا برنامه های فضای سبز و سیاست گذاری مناسب است؟

Urban green infrastructure (UGI) planning, based on certain principles, has emerged as a way to conceptualise connected greenspace in urbanised environments. This is achieved through the application of processes and approaches linked to policy themes to which the concept can significantly contribute. Taken together the processes, approaches and policy themes constitute the principles of UGI, which when adopted can promote, maintain and enhance quality of life in resource-efficient, compact and climate-resilient cities. In this study we explore the extent to which strategic greenspace planning in Europe is UGI compliant, as we hypothesised that the above principles are presently under-represented in planning documents and policies. This was accomplished by conducting a comparative analysis of the adoption of UGI principles in current practices of greenspace planning across European city-regions based on a systematic review of previous data and reports. The study found that many UGI principles and related concepts are present to some degree in strategic greenspace planning in Europe. However, gaps exist with regard to their scope and level of consideration. Presently, conservation emerges as the predominant task in strategic urban greenspace planning. However, enhancing network connectivity is key to the development of UGI, hence a greater focus on the restoration and creation of greenspace is required in the future. Based on our analysis it can be concluded that the advancement towards UGI planning is well established and progressing, although some areas are markedly under-represented. Strategic greenspace planning in Europe, with a few exceptions, requires further development to be effectively considered as UGI compliant.
