With the rapidity of urbanisation, concerns about citizens’ mental wellbeing issues are on the rise, and simultaneously, the issue of land use conflicts is becoming increasingly prominent. As a nature-based solution, the role of urban green space has been continually emphasised in the past decade. In urban areas facing scarce land resources, improving the quality of green spaces appears to be an important approach. This review aimed to systematically elaborate the studies regarding the associations between urban green space (UGS) qualities and mental wellbeing, following the Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twenty-two articles were included, and most of them had a cross-sectional design. From the analysis of the data, it emerged that the definition of the quality of green space is heterogeneous. Natural elements, particularly vegetation diversity and water features, consistently showed positive associations with mental wellbeing, while the effects of spatial features like accessibility showed mixed results. The impact of facilities and amenities appeared more complex, with their benefits heavily dependent on the design and maintenance. More evidence is needed to determine the mental wellbeing benefits of maintenance and the development of facilities and amenities for UGSs. In addition, the assessment of mental wellbeing relied on various self-reported scales, with different scales targeting different aspects. Instrumental measurements were rarely employed. Future research should employ more rigorous experimental methods and standardised quality assessment tools.

Rapid urbanisation has highlighted the importance of urban green spaces (UGS) in promoting environmental sustainability and human wellbeing, yet the gap between urban planning practices and community preferences remains a significant challenge. This study investigated residents’ perceptions and attitudes towards UGS in a neighbourhood of an Italian city (Quartiere Marconi, Imola), focusing on understanding both the strengths and limitations of existing public green spaces from users’ perspectives. Through a comprehensive questionnaire survey of 126 residents, we examined the associations between socio-demographic characteristics and four aspects of UGS utilisation: visiting purposes, barriers to visits, satisfaction levels, and suggestions for improvement. Chi-square tests were conducted to identify significant relationships. The results indicate that life stage, rather than scattered socio-demographic factors, plays a crucial role in shaping UGS perceptions and usage patterns. Particularly, the 31–45 and 46–60 age groups, characterised by family-caring and career responsibilities, showed distinct preferences for social activities, while individual users focused more on nature enjoyment. Although accessibility was generally sufficient, satisfaction levels varied significantly based on living arrangements, with families emphasising facility-related issues and individual users prioritising natural features. These findings suggest that successful UGS planning requires attention to both high-quality natural elements and user-oriented facilities to meet the diverse needs of different life stages. This study represents the preliminary phase of a project, which concerns the redevelopment of the area under study, in order to create a more inclusive and high-quality UGS, taking into account the needs of the resident population.

In recent decades, extensive evidence has indicated that green spaces and physical activity (PA) are associated with mental health, while limited research has explored the combined effects of supervised PA in urban green spaces. To address the research gap, this study examines whether supervised PA within green spaces improves mental health among middle-aged adults (45–65 years) through a quasi-experimental longitudinal study developed as part of the “Moving Parks” project in Bologna, Italy. Using the Italian version of the Warwick–Edinburgh Mental Well-being Scale (WEMWBS), mental health was measured at pre- and post-assessment. A total of 340 participants (258 intervention, 82 control) were included in the study. The effects of intervention, group assignment, and their interaction on mental health scores were analysed using a two-way repeated measures ANOVA. No significant differences in mental health improvements were observed between the intervention group and control group. The results indicated significant main effects of time on total WEMWBS scores and several subscales such as optimism, usefulness, energy, and cheerfulness, but these changes were not significantly influenced by group assignment. The only significant group-by-time interaction was found in perceived usefulness. These findings do not provide conclusive support for the hypothesised benefits of the supervised PA intervention. Possible explanations include seasonal variation, baseline or ceiling effects, and the potential limitations of the WEMWBS in detecting short-term psychological changes. Future research should consider extending intervention duration, improving group comparability, and employing more sensitive assessment tools to better evaluate the mental health impact of green space–based PA programmes.

Urban green spaces (UGSs) are increasingly recognised as critical infrastructure for mitigating climate extremes and promoting public health; indeed, the microclimatic mechanisms through which vegetation structure translates into measurable improvements in human comfort at the neighbourhood scale are of significant interest, particularly in the context of new urban developments. This study examines the cooling effects of an urban redevelopment project in the Marconi district of Imola, Italy, using ENVI-met (Version 6.0.0, ENVI-met GmbH, Essen, Germany) simulations to compare ex ante (current) and ex post (planned) scenarios under extreme heat conditions. Physiological Equivalent Temperature (PET) was computed at the pedestrian level for both standard adult and elderly models to assess spatial patterns of thermal comfort. The results demonstrate that tree canopies are the primary determinant of local cooling, with newly planted trees reducing PET by up to 3.5 °C at the core of the regenerated block and by 1–2 °C along adjacent pavements, while grass and low vegetation provided negligible mitigation. However, new buildings generated localised warming bands of 0.5–2 °C along façades, revealing a trade-off between densification and outdoor liveability. Elderly populations experienced slightly stronger thermal stress near buildings, highlighting spatial concentrations of vulnerability. These findings reinforce the need to prioritise tree planting and canopy management as core climate adaptation strategies, while simultaneously addressing near-building heat accumulation through integrated design approaches such as façade greening and ventilation preservation. The study demonstrates the value of spatially explicit microclimate simulation for evidence-based urban planning, contributing to the development of sustainable and liveable urban environments.
