Abstract
The goal of this study is to find the locations of critical deficiency or absence of urban green space (UGS) in Kyiv in order to determine the locations of priority UGS planning and mitigate climate change effects. To achieve this goal, we found actual UGS areas within Kyiv limits, analysed their spatial distribution and calculated the greenery levels in each of the ten districts in the capital. Using QGIS tools, we calculated the geometric UGS characteristics and processed 3,548 contours within city limits. Based on own calculations, we built a map chart of Kyiv UGS and filled it in with relevant information. Since the UGS distribution in different Kyiv districts is very uneven, a significant indictor of protection of inhabitants from adverse climate change effects is the population density and size with respect to the greenery level. Then we also found the average UGS provision per person and detected significant differences even in some neighbouring districts. By comparing the results of calculating the greenery level and the provision of green spaces with the location of heat islands in Kyiv, we obtained precise sites of critical exposure of population to climate change effects. The map chart that was built based on these data can serve as a guide for priority UGS planning to protect Kyiv inhabitants from heat waves and heat stress.
