Exploring Associations between Subjective Well-Being and Non-Market Values When Used in the Evaluation of Urban Green Spaces: A Scoping Review

Proximity and access to urban green spaces (UGSs) provide city dwellers with multiple benefits related to health and well-being. Understanding what (and how) characteristics of these spaces affect individuals' perceived preferences and sense of well-being (subjective well-being) could be critical for relevant future planning interventions, policy design, and investments in green spaces. This scoping review aims to summarize, synthesize, and compare previous research findings about the application of (stated) preference-based methods, using non-market valuation techniques (e.g., willingness-to-pay methods), and non-preference-based measures of well-being (e.g., subjective well-being) to evaluate UGSs. By comparing these two methodologies, we aim to explore the differences and similarities among the determinants of benefits associated with UGS design and planning. We also seek to identify the most commonly used research approaches for measuring and/or projecting the impact of (new or rejuvenated) UGSs on people's welfare and well-being. The review focuses on peer-reviewed empirical scientific work published during the period from 2010 to 2022.
