Abstract
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.

IntroductionThey do indicate, the emergence of some interesting research topics, which may act as a possible roadmap for future research (Table 1)
We used the following three: (1) Are there any variables that could help predict the dynamics of open green areas” (OGA) beyond the particularities of the two countries analyzed? (2) Can the subsequent differences between the dynamics of OGA in the two countries be attributed to a particular planning system or not? In a sense, these two preliminary questions served to pave the way for a third, more critical, question: (3) What insights can we offer to planning practitioners based on our analysis? Though unremarkable at first, this final question strikes directly at the crux of the matter, by making planning professionals aware of the subtler implications of the current planning research
The lack of coverage by plans in Poland and the derogatory over-planning in Romania had the same effect: development occurred spontaneously, driven by economic and political forces, and did not account for Green Infrastructures (GI), which were fragmented and lost in both countries
