ABSTRACT

Green infrastructure and nature-based solutions (NBSs) are, especially in urban areas, one of the key elements in building a friendly living environment that contributes to healthy longevity. This paper presents a novel method for assessing the accessibility of recreational urban green space (RUGS) at the level of individual residential buildings. We designed and piloted a new total accessible recreational urban green space area (TARUGS) index, based on real pedestrian network distances, considering spatial accessibility weighted by the total area of green space available within an approximate 15-min walk. Calculations were carried out individually for each residential building and each individual RUGS, using GIS technologies, including network analysis. The developed methodology allows for the detection of local inequalities in access to all city RUGSs. It enables the inclusion of additional socioeconomic variables in an in-depth spatial equity analysis. The RUGS accessibility ranking of buildings provides a practical tool to support urban intervention planning, as well as the design of solutions that respond to the real needs of residents and environmental challenges. Availability analyses were performed for 108,618 buildings and 146 RUGS. Areas with the highest and clearly insufficient access to RUGS in Warsaw were identified. Over 40,400 buildings were classified as having no access to RUGS (class 0), which accounts for 37% of all residential buildings, while 21,700 buildings were classified as having the best access (class 4), which accounts for 20% of all residential buildings. The districts of Wilanów and Włochy have the worst accessibility, while Wawer and Mokotów have the best. The proposed building-level methodology quantitatively reveals spatial inequalities in access to RUGS, enabling data-driven, equitable planning decisions while highlighting the need to integrate broader accessibility modes, subjective user experiences, and data improvements for a comprehensive assessment of spatial justice. The framework demonstrates how advanced geospatial data analysis, integrating GIS technologies, open data, and network-based innovative solutions, could enhance urban policy-making, improve the design of equitable public spaces, and support resilient land management strategies.
