Transit-Oriented Development (TOD), formalized by Calthorpe and Poticha in 1993, emerged to counter urban sprawl, reduce car dependency, and revitalize historical community centers. Rooted in “new urbanism”, TOD emphasizes integrated regional land-use planning and high-capacity public transportation. In the Middle East, TOD implementation remains understudied, particularly regarding heritage integration and social equity in arid climates. Doha’s rapid social and economic transformation presents both opportunities and risks: growth offers urban revitalization yet threatens to displace communities and dilute cultural identity. Shifts in urban planning have aimed to address sustainability, connectivity, and heritage preservation. This study examines Msheireb Downtown Doha (MDD) to assess how TOD can restore historic districts while managing gentrification, enhancing accessibility and promoting inclusiveness. A mixed-methods approach was applied, including 12 semi-structured interviews with stakeholders (Qatar Rail, Msheireb Properties, Ministry of Municipality and Environment), purposive surveys of 80 urban users, site observations, and spatial mapping. Using the Node-Place-People (NPP) model, the study evaluates TOD effectiveness across transportation connectivity (node), built environment quality (place), and equity metrics (people). The findings show that MDD successfully implements fundamental TOD principles through its design, which enhances connectivity, walkability, social inclusiveness, and heritage preservation. However, multiple obstacles remain: the “peripheral island effect” limits benefits to the core, pedestrian–vehicular balance is unresolved, and commercial gentrification is on the rise. This research provides evidence-based knowledge for GCC cities pursuing sustainable urban regeneration by demonstrating both the advantages of TOD and the necessity for critical, context-sensitive implementation that focuses on social equity together with physical transformation.

With the ongoing advancement of urbanization, the renewal of old urban areas has emerged as a central front in enhancing urban quality, with street space improvement playing a pivotal role in advancing sustainable urban development. This study focuses on Chengdu, a highly urbanized megacity, employing a combination of multi-point continuous street view photography, spatial mapping, and landscape design interventions to systematically examine human activity patterns, commercial dynamics, and pathways for spatial optimization along the street-facing interfaces of old residential neighborhoods and their adjacent urban streets. The findings reveal that: (1) commercializing the street-facing façades enhances local employment opportunities; (2) window-type fences demonstrate superior adaptability by effectively balancing commercial accessibility with resident safety; and (3) a diverse mix of commercial types sustains the vitality of street-level economies in these areas. These results not only offer actionable spatial strategies for the renovation of old residential zones in Chengdu but also contribute transferable insights for urban regeneration efforts globally.

This follow-up study investigates the long-term environmental sustainability and remediation outcomes of the UPPER (‘Urban Productive Parks for Sustainable Urban Regeneration’-UIA04-252) project in Latina, Italy, focusing on Nature-Based Solutions (NbS) applied to urban green infrastructure. By integrating proximal and satellite-based remote sensing methodologies, the research evaluates persistent improvements in vegetation health, soil moisture dynamics, and overall environmental quality over multiple years. Building upon the initial monitoring framework, this case study incorporates updated data and refined techniques to quantify temporal changes and assess the ecological performance of NbS interventions. In more detail, ground-based data from meteo-climatic, air quality stations and remote satellite data from the Sentinel-2 mission are adopted. Ground-based measurements such as temperature, humidity, radiation, rainfall intensity, PM10 and PM2.5 are carried out to monitor the overall environmental quality. Updated satellite imagery from Sentinel-2 is analyzed using advanced band ratio indices, including the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Water Index (NDWI) and the Normalized Difference Moisture Index (NDMI). Comparative temporal analysis revealed consistent enhancements in vegetation health, with NDVI values significantly exceeding baseline levels (NDVI 2022–2024: +0.096, p = 0.024), demonstrating successful vegetation establishment with larger gains in green areas (+27.0%) than parking retrofits (+11.4%, p = 0.041). However, concurrent NDWI decline (−0.066, p = 0.063) indicates increased vegetation water stress despite irrigation infrastructure. NDMI improvements (+0.098, p = 0.016) suggest physiological adaptation through stomatal regulation. Principal Component Analysis (PCA) of meteo-climatic variables reveals temperature as the dominant environmental driver (PC2 loadings > 0.8), with municipality-wide NDVI-temperature correlations of r = −0.87. These multi-scale findings validate sustained NbS effectiveness in enhancing vegetation density and ecosystem services, yet simultaneously expose critical water-limitation trade-offs in Mediterranean semi-arid contexts, necessitating adaptive irrigation management and continued monitoring for long-term urban climate resilience. The integrated monitoring approach underscores the critical role of continuous, multi-scale assessment in ensuring long-term success and adaptive management of NbS-based interventions. Full article

This paper addresses the problem of imbalance between coastal and inland areas and recognises the reuse of abandoned buildings as an evolutionary regeneration strategy which, through specific interventions linked by a system of routes for tourism and sport, can gradually trigger sustainable development on a regional scale. It presents research conducted in recent years on behalf of local administrations and continued in national and European projects. The reference context is the Abruzzo region, where coastal, hilly and mountainous areas are a short distance apart and include both densely built-up and populated urban centres and small depopulated towns surrounded by landscapes of high environmental value. The objective is to define, through the responsible use of built resources, viable and sustainable strategies for regeneration and rebalancing oriented towards the concept of transformative resilience. The methodology adopted is divided into phases and includes both theoretical developments and case study applications according to an approach that networks building restoration and reuse interventions in the region. The key results consist of defining a reuse logic that considers the regional territory as a whole, linking different resources, functions and environments. This logic, which envisages the organisation of new functions on a regional scale, emphasises the capacity of building reuse to produce positive effects on the territory and trigger socio-economic development dynamics. This research forms part of the experience underlying a project of significant national interest (PRIN 2022 TRIALs), which will provide guidelines for activating the transformative resilience capacities of inland areas of central Italy.

This paper develops a new conceptual and operational understanding of cultural heritage transformation, interpreting it as a systemic and dynamic process rather than a static state. It explores the realities and opportunities for action when cultural heritage is understood and managed as a complex, adaptive system. The study builds on a critical review of contemporary literature to identify the multi-scalar challenges currently facing urban heritage systems, such as climate change, disaster risks, social fragmentation, and unsustainable urban development. To respond to these challenges, the paper introduces a metamodel for heritage-based urban transformation, designed to apply systems thinking to heritage management that was developed based on cases from the Western European context. This metamodel integrates key variables—actors, resources, tools, and processes—and is used to test the hypothesis that a systems-oriented approach to cultural heritage can enhance the capacity of stakeholders to connect, adapt, use, and safeguard heritage in the face of complex urban transitions. The hypothesis is operationalized through scenario-based applications in the fields of disaster risk management (DRM), circular economy, and broader sustainability transitions, demonstrating how the metamodel supports the design of cross-over resilience strategies. These strategies not only preserve heritage but activate it as a resource for innovation, cohesion, identity, and adaptive reuse. Thus, cultural heritage is reframed as a strategic investment—generating spillover benefits such as improved quality of life, economic opportunities, environmental mitigation, and enhanced social capital. In light of the transition toward a greener and more resilient society, this paper argues for embracing heritage as a driver of transformation—capable of engaging with well-being, behavior change, innovation, and education through cultural crossovers. Heritage is thus positioned not merely as something to be protected, but as a catalyst for systemic change and future-oriented urban regeneration. Full article

This study aims to explore how industrial heritage regeneration spaces influence employees’ physical and psychological health through restorative perception. With the rapid urbanization and increasing emphasis on sustainable development, the adaptive reuse of industrial heritage sites has become a vital strategy in urban renewal. However, the impact of such spaces on people’s health remains underexplored, especially in terms of how the work environment and restorative psychological mechanisms interact. Using a cross-sectional survey design, data from 486 employees in adaptive reuse projects across major cities in China were analyzed through Structural Equation Modeling (SEM). Employees were chosen as the target population because they represent a group with stable, repeated, and long-term exposure to the regenerated environment during daily routines. Compared with visitors, whose exposure duration, activity purposes, and spatial routes are highly variable, employees provide a more consistent context to test the proposed restorative mechanisms. The results revealed that industrial heritage attribute perception (IHAP), including scale, materiality, historical presence, and functional transformation, significantly predicted restorative perception (β = 0.546, p < 0.001), which in turn positively influenced both psychological health (β = −0.647, p < 0.001) and physical health (β = 0.688, p < 0.001). Instrumental variable analysis using “building age” and “green coverage rate” confirmed the robustness of these findings, showing that restorative perception still significantly improved mental (β = −2.295, p < 0.001) and physical health (β = 0.528, p < 0.001) after addressing endogeneity issues. Furthermore, individual differences such as work tenure (β = 0.239, p < 0.001) and environmental sensitivity (β = 0.054, p > 0.05) moderated these effects. This study extends Attention Restoration Theory (ART) by applying it to historical industrial environments, offering both theoretical insights and practical guidance for designing adaptive reuse spaces that promote employee well-being.

Mega-event-led urban waterfront regeneration has played a key role in shaping public open spaces, particularly in newly developed areas within the Chinese context. However, public perceptions and their influence on the use of newly built open spaces created through mega-event-led regeneration have not been examined in existing research. To address this gap, this study establishes an integrated assessment framework to evaluate the quality of urban waterfront open spaces. A mixed methods approach was adopted, including direct observations and 770 online questionnaires collected between July and October 2024 at the South Bank of the Qiantang River (SBQR) in Hangzhou, China. Spatial analysis and Importance–Performance Analysis (IPA) were employed to determine priority improvement areas that should inform future waterfront regeneration strategies. The results indicate that inclusiveness emerged as the most important factor for enhancing waterfront open space quality, while spatial aesthetics ranked the lowest. Among the sub-sub factors, elements related to improving water accessibility, enhancing natural surveillance, providing artificial shelters and diverse seating options, introducing distinctive water features, and shaping collective memory through digital technologies are the key priorities for improvement in the future urban waterfront regeneration policies. Finally, the study highlights that the intangible legacies of the Asian Games and the adaptive reuse of informal built heritage have the potential to reshape a distinctive new city image and collective memory, even in the absence of tangible and formally recognised heritage buildings.

Air pollution is a major but often under-integrated driver of forest dynamics at the global scale. This review combines a bibliometric analysis of 258 peer-reviewed studies with a synthesis of ecological, physiological, and biogeochemical evidence to clarify how multiple air pollutants influence forest structure, function, and regeneration. Research output is dominated by Europe, East Asia, and North America, with ozone, nitrogen deposition, particulate matter, and acidic precipitation receiving the greatest attention. Across forest biomes, air pollution affects growth, wood anatomy, nutrient cycling, photosynthesis, species composition, litter decomposition, and soil chemistry through interacting pathways. Regional patterns reveal strong context dependency, with heightened sensitivity in mountain and boreal forests, pronounced ozone exposure in Mediterranean and peri-urban systems, episodic oxidative stress in tropical forests, and long-term heavy-metal accumulation in industrial regions. Beyond being impacted, forests actively modify atmospheric chemistry through pollutant filtration, aerosol interactions, and deposition processes. The novelty of this review lies in explicitly framing air pollution as a dynamic driver of forest change, with direct implications for afforestation and restoration on degraded lands. Key knowledge gaps remain regarding combined pollution–climate effects, understudied forest biomes, and the scaling of physiological responses to ecosystem and regional levels, which must be addressed to support effective forest management under global change.

This paper presents the results of an integrated research and design process developed within the Master’s study programme in Architecture at the University of Belgrade—Faculty of Architecture, aimed at exploring architectural agency in conditions of ecological degradation, declining biodiversity, and the urgent need for regenerative transformation of the built environment. Moving beyond technologically driven notions of “green design,” the study investigates architectural approaches that support ecosystem restoration, biodiversity enhancement, and multispecies coexistence while strengthening health and well-being. Grounded in a three-phase methodological framework, the research (1) formulates conceptual models of therapeutic landscapes through typo-morphological, place-based, and adventure-based analytical approaches; (2) evaluates these models using the New European Bauhaus (NEB) Checklist to assess their alignment with the core values of sustainability, beauty, and togetherness; and (3) synthesizes the findings into regenerative design scenarios that integrate ecological processes, multisensory experience, and community participation. The results position therapeutic landscapes as a spatial practice in which architecture functions as ecological infrastructure, a metabolic system where natural cycles, cultural meanings, bodily experiences, and more-than-human agencies interact. In this sense, architectural design becomes the basis for re-naturalization, regeneration, ecological care, multisensory experience, and resilience in urban, peri-urban, and rural communities.

Developing effective evaluation frameworks for urban regeneration in non-metropolitan areas is increasingly challenging, particularly for small-scale projects where conventional administrative indicators are often insufficient on their own. This study examines 46 regeneration projects in Republic of Korea and integrates nighttime lights (NTL), Sentinel-2 indices, and administrative statistics to identify how different project types produce observable changes. The results show that NTL is effective mainly in economy-based and central commercial area projects, where increases in radiance correspond to the expansion of commercial functions, higher business activity, and stronger evening economic operations. In contrast, NTL shows limited responsiveness in residential-support projects, reflecting the low baseline illumination and weak lighting elasticity of residential environments. For these areas, Sentinel-2 NDVI and NDBI provide clearer evidence of improvements, capturing localized changes in vegetation, built surfaces, and pedestrian environments that are not detectable through nighttime radiance. Comparative assessments indicate that most changes are concentrated within project boundaries, though external development projects occasionally influence spectral patterns in adjacent areas. These findings demonstrate that combining NTL and Sentinel-2 data offers a more context-sensitive approach to evaluating small-scale regeneration and highlights the importance of selecting indicators suited to specific project types. The study provides an empirical foundation for more adaptable, data-driven evaluation frameworks in non-metropolitan regeneration policy. Full article

Against the backdrop of urban renewal and population ageing in China, elevator retrofitting in older residential compounds has emerged as a critical yet contentious issue, primarily due to uneven cost-sharing and perceived inequities in the distribution of benefits. This study employs a combined empirical framework integrating Difference-in-Differences (DID) and cost–benefit analysis to systematically evaluate the economic impacts of elevator installation in older neighbourhoods of Hangzhou. Using transaction data from 879 housing units across 18 residential compounds between 2018 and 2020, along with actual project cost records, we quantify the premium effects and assess economic feasibility. The results show that elevator retrofitting leads to an overall 5.53% increase in housing prices, with significant vertical differentiation: upper-floor units appreciate by 8.10%, middle-floor units by 4.58%, and lower-floor units by 1.59%. Further analysis confirms that the aggregate increase in property value fully covers installation costs, long-term maintenance, and reasonable compensation for lower-floor residents, thereby achieving a Pareto improvement. The study establishes a floor-gradient linkage mechanism between value uplift and cost-sharing, providing a quantifiable basis for policy design and community negotiation. These findings challenge the prevailing zero-sum view of elevator retrofitting while offering a replicable model for urban renewal that equitably balances stakeholder benefits. Full article

This study aims to identify how individual-level and neighborhood-level factors are associated with residential satisfaction in urban regeneration areas. We conducted a survey of 281 adult residents recruited on-site at six urban regeneration community facilities (URCFs) that had been in operation for at least one year in Daegu, South Korea, and constructed neighborhood-level built environment factors using GIS. Multilevel regression analysis was applied to simultaneously examine how individual-level (level 1) and neighborhood-level (level 2) factors are associated with residential satisfaction. The results indicated that residents who participated more actively in urban regeneration activities reported higher levels of residential satisfaction, and that age integration was also significantly associated with greater satisfaction. Among neighborhood-level built environment factors, a lower proportion of old housing and higher levels of normalized difference vegetation index (NDVI) and water area were related to higher residential satisfaction. These findings indicate that residential satisfaction in urban regeneration areas can be better understood when individual-level characteristics and neighborhood-level built environmental conditions are considered together, highlighting the importance of a multilevel approach that accounts for both levels simultaneously.

Wastewater treatment is fundamental to sustainable urban development, and recent European legislation now requires quaternary treatment of final effluent at wastewater treatment plants. Among the technologies evaluated for this purpose, adsorption and Advanced Oxidation Processes (AOPs) have demonstrated the highest removal efficiencies, and the ongoing shift toward more circular and sustainable urban wastewater management, positioning them as two of the most strategically significant technologies in the field. Quaternary treatments with ozonation and activated carbon adsorption (PAC/GAC) achieve median micropollutant removal above 80%. GAC is generally associated with the highest costs, followed by PAC and ozonation, typically in the range of approximately 0.035 to 0.3 € per cubic meter in European settings. This review presents a systematic comparison of adsorption and AOPs for the removal of urban wastewater pollutants, with emphasis on removal efficiency, energy requirements, carbon footprint, and operational limitations. It delineates the conditions under which each technology demonstrates superior performance and highlights its complementary strengths across different contaminant groups and treatment objectives. Beyond conventional performance indicators, the review frames these technologies as key enablers of circular wastewater treatment through material regeneration, resource recovery, and process integration.

This paper examines the role of institutional logics in shaping heritage-led urban regeneration across fifteen adaptive reuse projects of former tobacco factories in Europe. By categorizing managing authorities into public, private, and community-led actors, the study interprets regeneration outcomes, such as community participation, tourism growth, and crime reduction, through the lens of institutional theory. The analysis reveals that each authority type operates under distinct logics: regulative (public), market-driven (private), and normative (community), which significantly influence the depth and type of impact achieved. Through a comparative framework and empirical indicators, the paper highlights how institutional arrangements affect not only project design but also questions of inclusion, identity, and sustainability. Findings challenge simplistic binaries of top-down versus bottom-up governance and offer a more nuanced understanding of how urban heritage can serve divergent values. The paper concludes with implications for urban policy and future research on hybrid and participatory models of heritage governance. Full article

The built environment plays a critical role in promoting residents’ physical activity, yet the interactive mechanisms between objective environmental factors and subjective perceptions remain insufficiently understood. This study examines three functionally distinct neighborhoods in Beijing’s Xicheng District—Xinjiekou (historic), Financial Street (administrative), and Baizhifang (residential)—representing typical urban regeneration contexts. Using an ordered logit model based on 1072 valid questionnaires, we analyze how objective and subjective built environment factors jointly influence residents’ leisure physical activities. Results reveal that socioeconomic attributes (income, age, education) are primary determinants of activity engagement. Among objective factors, facility accessibility and land-use mix exert the strongest direct effects, while subjective perceptions—particularly satisfaction with environmental attractiveness—significantly moderate these relationships. Based on these findings, we propose differentiated spatial renewal strategies tailored to each street type. This research provides empirical evidence for implementing health-oriented urban regeneration policies in high-density metropolitan areas. Full article
