As critical urban blue–green infrastructure, urban wetland parks serve as vital venues for visitors to obtain restorative experiences. However, existing studies primarily emphasize their ecological and economic benefits, with comparatively limited attention paid to their roles in promoting public mental health and enhancing well-being. Using Yanghu Wetland Park in Changsha as a case study, this research investigates how restorative environmental perception influences visitors’ well-being through two mediating variables: environmental preference and place attachment. A total of 251 valid responses were collected through field surveys and questionnaires. Structural equation modeling (SEM) was employed to empirically examine the relationships among the variables. This study enriches the theoretical framework of environmental psychology and urban landscape behavior research. It also provides evidence-based insights into the planning and design of urban wetland parks, contributing to the enhancement of public well-being and overall life satisfaction. Full article

Family Allotment Gardens (FAGs) represent key components of urban cooling and air-purification systems. However, research has mainly focused on their social roles and on their contributions to food production. This study quantified the capacity of FAGs in Warsaw (Poland) to provide two key ecosystem services at distances up to 300 m from their boundaries: air-pollution filtration and microclimate regulation. Measurements of particulate matter (PM1, PM2.5, PM10), air temperature and relative humidity were conducted along transects inside and outside three allotment complexes in autumn 2023, a period characterised by increased traffic emissions and elevated particulate levels. The results show a moderate but significant reduction in PM concentrations inside gardens (by about 2 µg/m³; r = 0.22–0.29) and slightly higher humidity (by 2.1%; r = −0.34). The cooling effect was weak (<0.3 °C; r = 0.06), indicating a limited spatial range under autumn conditions, though selected transects exhibited stronger local effects. The results confirm that FAGs can contribute to air purification and local climate regulation, but their effectiveness depends on vegetation structure and urban context. Strengthening their role requires integration with green-infrastructure planning and emission-reduction practices within gardens. FAGs, beyond their recreational and productive value, should be recognised as active components of urban adaptation strategies. Full article

In the context of high renewable energy penetration and increasing supply–demand imbalances, power grid companies face complex challenges in load control due to multiple constraints. Based on the actual operational context of power grid companies in China, this study systematically analyzes the key constraints on load control from an industrial chain perspective. First, a systematic analytical framework is constructed from an industrial chain perspective to identify the factors constraining load control in power enterprises. Then, by integrating in-depth qualitative insights with a rigorous quantitative analysis, we propose an analytical method for identifying key constraining factors using a novel interactive group Decision Making Trial and Evaluation Laboratory (DEMATEL) approach. Finally, using Yunnan Power Grid Company in China as a case study, we identify specific constraining factors, including power generation costs, electricity pricing policies, distribution equipment capacity, and the level of grid intelligence. Based on the findings, this study proposes to establish a multi-dimensional coordination mechanism for Yunnan Power Grid, encompassing infrastructure-driven planning, policy–technology synergy, and cost-transmission optimization. This integrated approach will systematically enhance load control capabilities and support the transition toward a green, low-carbon power system. Full article

In the context of urban stock renewal, coordinating spatial fairness with low-carbon goals remains a critical challenge. Existing planning often leads to spaces that are “nominally compliant but functionally ineffective,” failing to support low-carbon behaviors. To address this, this study adopts a spatial justice framework coupled with space syntax technology to empirically analyze the structural defects of the Beijing Baiwanzhuang Community and their constraints on low-carbon behaviors. We utilized a “Moving Snapshot Observation” method to collect behavioral data and constructed a quantitative regression model to identify the key drivers of elderly gathering (a proxy for low-carbon behavior). The results reveal “significant spatial differentiation and accessibility fractures” within the physical space, where structural imbalances lead to systematic spatial deprivation. Specifically, the multivariate regression analysis (R² = 0.50) indicates that low-carbon behaviors are significantly associated with a “dual-core mechanism”: community-scale spatial integration (NAIN 3600 m) and the density of seating within a short radius (100–200 m). A key finding indicates that the driving role of spatial network accessibility is significantly stronger than facility abundance alone. Based on this, a “Space-Facility-Governance” collaborative reconstruction paradigm is proposed, including using green infrastructure to stitch spatial fractures, precisely configuring low-carbon facilities at high-integration nodes, and establishing inclusive governance mechanisms. This research breaks through the limitation of traditional spatial justice studies that focus on qualitative critique, constructing a “physical spatial structure–low-carbon behavior” quantitative attribution model. It empirically validates that “accessibility justice” is a prerequisite for achieving community low-carbon transitions, providing a quantitative renewal paradigm that balances equity and efficiency for existing communities.

Urban heat islands (UHIs) have intensified in rapidly urbanizing regions like New York, exacerbating thermal discomfort, public health risks, and energy consumption. While previous research has highlighted various environmental and socioeconomic contributors, most existing studies lack interpretable, fine-scale models capable of quantifying the effects of specific drivers—limiting their utility for targeted planning. To address this challenge, we develop an interpretable machine learning framework using Random Forest and XGBOOST to predict land surface temperature across 1800+ census tracts in the New York metropolitan area, incorporating vegetation indices, water proximity, urban morphology, and socioeconomic factors. Both models performed strongly (mean R² ≈ 0.90), with vegetation coverage and water proximity emerging as the most influential cooling factors, while built form features played supporting roles. Socioeconomic vulnerability indicators showed weak correlations with temperature, suggesting a relatively equitable thermal landscape. Optimization simulations further revealed that increasing vegetation to a threshold level could lower average surface temperatures by up to 6.38 °C, with additional but smaller gains achievable through adjustments to water access and urban form. These findings provide evidence-based guidance for climate-adaptive urban design and green infrastructure planning. More broadly, the study illustrates the potential of explainable machine learning to support data-driven environmental interventions in complex urban systems. Full article

(1) Background: As social infrastructures, cemeteries have always played a central role in various human cultures. The changing function of cemeteries and the recognition of their potential as green spaces have resulted in the fact that cemeteries are a subject of considerable urban planning research. However, there still is a knowledge gap for the case of Vienna. In this study, from the perspective of urban planning and the city of Vienna as an operator of interdenominational cemeteries on the one hand, and of operators of denominational cemeteries on the other hand, consideration of cemeteries in strategic urban planning is discussed, and prospects for the future are outlined. (2) Methods: A qualitative content analysis of relevant strategic planning documents and a qualitative theme-centred stakeholder survey using guideline interviews were conducted. The results were put into the context of the international literature. (3) Results: Cemeteries are an integral part of urban morphology and fabric. Interdenominational cemeteries serve multiple purposes, for example, as places of remembrance, leisure and recreation. In addition, the growing importance of interdenominational cemeteries in particular as green infrastructure for the public is evident. (4) Conclusions: Despite population growth and the associated pressure on land and densification, no changes such as the decommissioning of cemeteries are to be expected in the medium term.

Climate change is altering hydrological regimes across the North Aegean and Marmara regions of Türkiye, with increasing relevance for both drought occurrence and flood generation. This study examines long-term variability in temperature, precipitation, and evaporation using meteorological observations over a long time series and relates these changes to urban water management issues. Daily records from 12 meteorological stations, with data availability varying by station and extending back to 1926, were analysed using the non-parametric Mann–Kendall trend test and Sen’s slope estimator. The results indicate statistically significant warming trends across all stations, with several locations recording daily maximum temperatures exceeding 44 °C. Precipitation trends exhibit pronounced spatial heterogeneity: while most stations show decreasing long-term tendencies, others display unchanging or non-significant trends. Nevertheless, extreme daily rainfall events exceeding 200 mm are observed at multiple coastal and island stations, indicating a tendency toward high-intensity precipitation. Evaporation trends also vary across the region, with increasing rates at stations such as Tekirdağ and Çanakkale and decreasing trends at Bandırma and Yalova, reflecting the influence of local atmospheric conditions. Taken together, these findings point to a coupled risk of intensified flooding during short-duration rainfall events and increasing water stress during warm and dry periods. Such conditions challenge the effectiveness of conventional grey infrastructure. The results are therefore interpreted within the framework of the Sponge City approach, which emphasizes permeable surfaces, decentralized storage, infiltration, and the integration of green and blue infrastructure. By linking long-term hydroclimatic trends with urban design considerations, this study provides a quantitative basis for informing adaptive urban water management and planning strategies in Mediterranean-type climate regions.

This study is dedicated to analysing Ukraine’s transition to utilising renewable energy sources within the broader context of European integration, the decarbonization process, and the challenges significantly intensified by the full-scale Russia-Ukraine war in 2022. The objective of this study is to assess the effectiveness of managing Ukraine’s energy transition compared with selected European Union countries and to identify governance-related determinants of transition performance. The energy transition process is viewed as a cornerstone for ensuring national resilience, food security, and strategic post-war recovery planning. Despite significant growth rates in installed capacity, stimulated primarily by the implementation of green tariffs and foreign investments, Ukraine faces a range of systemic barriers. These include regulatory uncertainty, war-related infrastructure damage, and institutional fragility. To comprehensively assess managerial effectiveness, a comparative approach is employed, integrating data from the Energy Transition Index, the Worldwide Governance Indicators, and the Bertelsmann Transformation Index for the period 2015–2023. Within the scope of this research, a comparative analysis is conducted of Ukraine with Poland, Romania, and Slovakia, countries that share a post-socialist legacy and experience in European integration. The obtained results demonstrate that, although Ukraine exhibits a relatively high growth index for renewable energy development, at 54.56%, it significantly lags behind its regional partners in the parameters of quality of state governance, policy implementation consistency, and strategic coordination. It is concluded that managerial effectiveness, defined as the complex interplay between institutional capacity, policy stability, and implementation efficiency, is a decisive factor for the success of the energy transition. The research recommendations encompass enhancing regulatory transparency, strengthening strategic planning, and intensifying the attraction of international investments. Full article

Green roofs have emerged as a key nature-based solution for improving environmental quality, strengthening urban resilience, and enhancing human wellbeing. In the hospitality sector—where sustainable design and guest experience increasingly intersect—the incorporation of green roof gardens is particularly significant. Urban hotels face heightened challenges related to elevated temperatures, reduced green space, and the growing need for restorative environments within dense urban settings. This study aims to examine how green roof gardens function as integrated ecological, social, and psychological infrastructures in hotel environments. It evaluates the extent to which rooftop green spaces contribute to environmental sustainability, enhance guest experience, and foster community connections. The research adopts a qualitative design combining a comprehensive literature review conducted at selected five-star hotels in Greece. Data from secondary sources and field-based assessments were thematically analyzed to identify recurring patterns in environmental performance, social use, and psychological benefits. Findings indicate that hotel green roof gardens act as multifunctional systems that deliver significant ecological benefits—such as improved microclimate regulation, stormwater retention, and biodiversity support—while simultaneously enriching social interaction and guest experience through accessible, esthetically appealing spaces. Observations further highlight their contribution to psychological wellbeing by offering restorative environments characterized by greenery, natural light, and panoramic views. The study concludes that green roof gardens represent an effective design strategy that integrates sustainability, hospitality experience, and urban wellbeing. Their application in hotels provides both conceptual insight and practical guidance for the development of more resilient, livable, and guest-centered urban environments. These findings underscore the importance of incorporating green roofs into contemporary tourism and urban planning practices. Full article

In the context of rapid population aging in China, ensuring pedestrian safety for older adults has become a critical concern, particularly in mountainous cities where the built environment’s role remains understudied. This study examines how built environment factors influence road traffic crashes involving older pedestrians in such terrains, aiming to propose targeted safety optimization strategies. Using ten-year road traffic crash data from Yuzhong District, Chongqing, the research employed both Standard Poisson Regression and Bayesian Poisson Regression models for analysis. Key findings indicate that crash frequency significantly increased with higher densities of footbridges and recreational facilities, as well as with a greater proportion of parks and green space, whereas it decreased with a higher land use mix, greater densities of educational facilities, and higher public transport stop density. The proportion of storage land and the density of medical facilities showed no significant effects. These results provide concrete, evidence-based guidance for urban planning and transportation management in mountainous cities to optimize pedestrian infrastructure and enhance walking safety for the elderly.

As urbanisation accelerates, land-use planning has become a challenging factor in cities’ sustainable development. This process is based both on the historical heritage of Central and Eastern European cities and on concepts combining urban planning with ecology. Cemeteries, traditionally viewed as places of remembrance, hold significant potential as ecological assets within urban environments. On the other hand, they are problematic in relation to the location, neighbourhood, and form of past/present human activity. Many of these aspects are regulated in the investigated countries. This paper examines sustainable cemetery planning from legal, ecological, and spatial perspectives, highlighting their role in addressing environmental challenges while preserving cultural and social values. The research draws on comparative case studies from eight Central and Eastern European countries, combining an analysis of international and national legal frameworks with a functional–spatial assessment of cemetery surroundings. In addition, an environmental survey conducted among experts and residents highlights diverse perceptions regarding cemetery functions and their integration into urban landscapes. The findings demonstrate that policy-based management and multifunctional design are essential for enhancing the ecological, cultural, and social value of cemeteries. Reframing cemeteries as multifunctional green spaces offers a practical pathway toward more resilient and environmentally responsible urban development. Some important differences between the following countries have been observed. Full article

Urban rivers are critical ecological and cultural assets facing accelerating biodiversity loss. This study examines the integrated redevelopment of the Jadro River spring in Solin, Croatia, where a protected ichthyological reserve intersects layered heritage and urban edges to enhance conservation and public value. Using a single-case study design that combines archival project documentation, participant observation by the architect–authors, and a post-occupancy review three years after completion, the analysis synthesizes ecological, social, and design evidence across planning, delivery, and operation phases. The project delivered phased visitor and interpretation centers, accessible paths and bridges, habitat-compatible materials, and formalized access management that relocated parking from riverbanks, reduced episodic pollution sources, and prioritized inclusive, low-impact use. Governance and programming established a municipal management plan, curriculum-ready interpretation, and carrying capacity monitoring, transforming an underused picnic area into an educational, recreational, and conservation-oriented public landscape while safeguarding sensitive habitats. A transferable design protocol emerged, aligning blue green infrastructure, heritage conservation, adaptive reuse, and social–ecological system (SES)-informed placemaking to protect the endemic soft-mouth trout and strengthen a sense of place and community stewardship. The case supports SES-based riverpark renewal in which conservative interventions within protected cores are coupled with consolidated services on resilient ground, offering a replicable framework for ecologically constrained urban headwaters.

Cultural ecosystem services (CESs) play a critical role in urban residents’ well-being, yet conventional evaluations rely heavily on green-space area and overlook how facility quality and basic services influence the delivery of actual cultural benefits. To address this methodological gap, this study develops a three-tier evaluation framework—service potential, actual supply capacity, and actual service utility—to quantify multistage attenuation in CES provision across 95 parks in seven central districts of Shenyang, China. The framework integrates 114 quantitative and qualitative indicators from field surveys, national facility standards, and perception-based assessments, enabling a scientifically robust and replicable assessment of how cultural benefits are transformed from ecological structure to human experience. Results reveal that single-index, area-based assessments substantially overestimate CES supply: district-level supply–demand ratios drop from 66 to 195% to only 11–55% once quality and basic services are incorporated. Comprehensive and special parks retain the highest CES potential, whereas community and linear parks undergo significant losses due to aging facilities, insufficient maintenance, and inadequate infrastructure. Education and cultural services exhibit the most severe shortages, with deficits reaching 59–84%, underscoring structural limitations in learning-oriented spaces. By distinguishing structural (quantity), functional (quality), and experiential (basic service) constraints, the framework provides clear diagnostic guidance for targeted planning and management. Its multistage structure also reflects broader principles of sustainable urban development: improving CES requires not only expanding ecological elements but also enhancing service quality, strengthening infrastructure, and promoting equitable access to cultural benefits. The framework’s generalizability makes it applicable to high-density cities worldwide facing land scarcity and green-space inequality, supporting efforts aligned with SDG 11 to build inclusive, resilient, and culturally vibrant urban environments.

Current assessments of urban green spaces (UGS) rely largely on two-dimensional (2D) indicators, which fail to capture the three-dimensional (3D) structure necessary for evaluating ecological functions and human exposure. Among these, the Normalized Difference Vegetation Index (NDVI) describes top-down canopy greenness from a nadir perspective, whereas the Green View Index (GVI) quantifies vegetation visibility at street level from a pedestrian perspective. Because the relationship between NDVI and GVI remains unclear, multi-indicator assessments become difficult to interpret, limiting their ability to jointly characterize urban greenery. To address these gaps, we develop a synergy framework that integrates remote sensing with street-view images. First, we aligned the observation scales through street-view depth estimation and converted NDVI into fractional vegetation cover (FVC) through nonlinear mapping to unify measurement units. Correlation experiments revealed that the consistency between GVI and FVC was weak across the city (R² = 0.27) but substantially stronger along arterial roads with continuous vegetation (R² = 0.61). On this basis, we design a Green Synergy Index (GSI) that combines FVC and GVI using fractional power-law adjustments and an interaction term to capture their joint effects. Robustness tests indicate that GSI effectively handles extreme or mismatched cases, differentiates greening patterns, and integrates complementary information from nadir and street views without numerical instability. Furthermore, we assess the consistency between GSI and land surface temperature (LST), showing that the proposed index improves explanatory power compared with FVC and GVI alone (by 5.6% and 8.8%, respectively). Application to the study area yields a mean GSI value of 0.44 on a 0–1 scale, with spatial variations closely associated with road geometry and functional zoning. This enables the identification of mismatched canopy and visibility segments and supports targeted, climate-sensitive green infrastructure planning. Full article

Green infrastructure and nature-based solutions (NBSs) are, especially in urban areas, one of the key elements in building a friendly living environment that contributes to healthy longevity. This paper presents a novel method for assessing the accessibility of recreational urban green space (RUGS) at the level of individual residential buildings. We designed and piloted a new total accessible recreational urban green space area (TARUGS) index, based on real pedestrian network distances, considering spatial accessibility weighted by the total area of green space available within an approximate 15-min walk. Calculations were carried out individually for each residential building and each individual RUGS, using GIS technologies, including network analysis. The developed methodology allows for the detection of local inequalities in access to all city RUGSs. It enables the inclusion of additional socioeconomic variables in an in-depth spatial equity analysis. The RUGS accessibility ranking of buildings provides a practical tool to support urban intervention planning, as well as the design of solutions that respond to the real needs of residents and environmental challenges. Availability analyses were performed for 108,618 buildings and 146 RUGS. Areas with the highest and clearly insufficient access to RUGS in Warsaw were identified. Over 40,400 buildings were classified as having no access to RUGS (class 0), which accounts for 37% of all residential buildings, while 21,700 buildings were classified as having the best access (class 4), which accounts for 20% of all residential buildings. The districts of Wilanów and Włochy have the worst accessibility, while Wawer and Mokotów have the best. The proposed building-level methodology quantitatively reveals spatial inequalities in access to RUGS, enabling data-driven, equitable planning decisions while highlighting the need to integrate broader accessibility modes, subjective user experiences, and data improvements for a comprehensive assessment of spatial justice. The framework demonstrates how advanced geospatial data analysis, integrating GIS technologies, open data, and network-based innovative solutions, could enhance urban policy-making, improve the design of equitable public spaces, and support resilient land management strategies.
