Social and Urban Policy Li, Q., Wu, R., & Zhu, P. (2025). Quality or quantity of urban greenery: Which matters more to mental health? Evidence from housing prices in the Pearl River Delta. Landscape and Urban Planning, 263, 105438. Focus of Study The study examines the relationship between urban green environments and mental well-being in Pearl River Delta, China, particularly about quality or quantity of urban greenery. The mediating roles of neighborhood ties and place attachment are studied. The results are that neighborhood ties and place attachment are important mediators between greenery and mental health; quality of greenery is more important than quantity. Interestingly, less wealthy populations enjoy better mental health improvements enabled by urban greenery, while neighborhood ties reduce the mental health bene ts of greenery for the wealthy. Policy Recommendations Policymakers should improve the provision of quality green spaces in big cities. Attention should be paid to less privileged populations, such as those living in villages and public rental housing. It is important to implement mental health policies with integrated indicators for evaluating urban greenery among neighborhoods. Finally, the mediating factors of neighborhood ties and place attachment demonstrate that despite urban greenery different needs of different groups must be addressed, for example, facilities which can enable socialization and workout are essential for older populations.
