Dynamics of Open Green Areas in Polish and Romanian Cities during 2006-2018: Insights for Spatial Planners

Studying green urban infrastructure is important because of its ecosystem services, contributing to the welfare and comfort of citizens, mitigation of climate changes, and sustainability goals. Urban planning can increase or diminish the performance of ecosystem services. Despite numerous studies on the green infrastructure-services-planning nexus, there are very few concrete planning recommendations. This study aims to provide such recommendations for a broader audience by analyzing the dynamic of open green areas in Polish and Romanian cities, connected with its drivers. A novel approach including mathematical modeling and geostatistical analyses was applied to Urban Atlas and statistical yearbooks data. The results indicated that open green areas were lost and fragmented in all Romanian and Polish cities during 2006-2018. The drivers included urban built-up areas, population and density, the number of building permits, number of new dwellings completed, number of employees, and total length of roads. The study also revealed a tremendous lack of consistent datasets across the countries using the same statistical indicators. Based on the findings, planners should aim to preserve and develop urban greenery and maintain its continuity. City managers should use more research and decision-making policy developers to develop targeted policies and scientists should develop planning manuals.

Automated summary

Studying green urban infrastructure is crucial for ecosystem services, climate change mitigation, urban development, and citizen welfare. Research findings showed that open green areas in Polish and Romanian cities have been lost and fragmented due to factors such as urban development, population density, and construction activities. Planners should focus on preserving urban greenery, city managers need targeted policies, and scientists can develop planning manuals to support these efforts.
