N2 - Public green spaces (PGS) in urban areas can both reduce ambient temperatures and provide a place for residents to visit and cool off on hot days while enjoying a range of health and biodiversity co-benefits. High indoor temperatures and social vulnerability (e.g., being elderly or infirm) increase the potential reliance on PGS visitation and their cooling features. As the severity of urban heat increases due to climate change and cities recognize the need for ensuring availability, access, and quality of PGS, research is needed to support their planning and equitable benefits across social groups and space. We use an online public participation GIS (PPGIS) survey to explore the degree of (spatial) equity in PGS visitation for cooling off during extreme heat in Bochum, Germany. Our study also aims to determine the degree of pubic reliance on cooling as an ecosystem service, what biophysical features shape preferences for visitation, and the distributive environmental justice of neighborhood green space. We find that residents are concerned about extreme heat and visiting PGS for cooling off is common. Their current use is relatively equitable in the study area but more focus is needed on aged and low-income groups as well as the provision of large trees, shade, and water features. Residents travel on average over 10 km from home to visit the most valued PGS for cooling, likely due to poor availability and quality in the urban core. Additionally, our research provides a methodological template enabling equitable spatial planning for climate change adaptation.
