About the PhD thesis

The study of subjective well-being (SWB) has gained increased attention in recent decades. Among the numerous identified determinants of SWB, the spatial context emerges as an important one [1, 2]. Its significance is validated by the enhanced explanatory power of SWB models incorporating spatial dimensions  [3, 4]. Concurrently, the profound impact of exposure to nature on individuals’ SWB is widely acknowledged in the literature [5, 6]. Particularly within the urban realm, Urban Green Spaces (UGSs) are found to have a pivotal role in enhancing sustainability and resilience, providing manifold benefits to health and well-being, as well as fostering social cohesion [7]. Despite the abundant scientific evidence establishing this positive relationship [8, 9], only a paucity of research investigates specific UGS attributes in association with SWB. Furthermore, just a scant portion of this research delves into distinguishing between objective and perceived attributes [9].

It is argued that this knowledge gap imposes an obstacle to practicing effective urban planning and policymaking that fosters people’s SWB. Therefore, this Ph.D. thesis explores the relationship and dynamics between UGS attributes and SWB, extending the frontiers of current knowledge. The research contributes to the field by acknowledging the complex nature of cities and therefore identifying both objective and perceived UGS attributes associated with higher SWB levels, along with pathways mediating this relationship. The adopted approach aims to produce a replicable and transferable model, thereby facilitating evidence-based decision-making.

The dissertation enhances the discourse about UGSs and SWB by employing a comprehensive theoretical framework, rigorous methodological tools, and robust data-informed approaches. Doing so will significantly inform the intersection of theory, methodology, and policy-oriented outcomes, yielding valuable insights and transferable findings with practical implications.
