Urban health, well-being, and equity—core objectives of Sustainable Development Goals (SDGs 3, 10, and 11)—have become key themes in contemporary urban planning research and landscape research. While existing studies focus predominantly on quantitative assessment, environmental exposure, and human mobility, the historical origins of health-oriented urban green space planning remain insufficiently explored. Focusing on Lingnan area as a representative case, this research investigates the emergence of public green space in late Qing cities and its early contributions to urban health and spatial governance. Through a systematic examination of American and British Gardens at the Thirteen Factories in Guangzhou, the planned public green space system of the Shameen concession, and the municipal greening practices of neighboring Hong Kong and Macao, the study further analyzes Zhang Zhidong’s tree-lined boulevard project along Changdi avenue as a key instance of localized institutional adaptation. Drawing on late-Qing and Republican newspapers, nineteenth-century Western travelogs and reports, historical and contemporary studies and photo albums, the study finds the following: (1) the American and British Gardens marked the earliest emergence of health-oriented urban green space in Lingnan area; (2) the systematically planned green space network of the Shameen concession constituted a prototypical form of health-oriented urban green space planning; (3) the botanical gardens, street-tree systems, public parks, and institutionalized management practices in Hong Kong and Macao exerted a strong regional demonstrative influence on Guangzhou; (4) the street-tree planting along Changdi Avenue represented a localized absorption of foreign planning paradigms and marked the institutionalization of municipal greening in Guangzhou. Although these early practices did not yet form a modern healthy city planning framework at that time, they played a crucial role in improving urban sanitation, enhancing public space quality, and shaping urban order. By tracing the historical trajectory from transnational demonstration to local adaptation and institutional consolihdation, this study provides new insights into the historical foundations of health-oriented urban planning in China and contributes a long-term perspective to contemporary debates on healthy cities and nature-based urban interventions.

This paper investigates a UAV-assisted wireless communication system that integrates optical wireless communication (LiFi) with conventional RF links to enhance network capacity in crowd-gathering scenarios. While the unmanned aerial vehicle (UAV) serves as a flying base station providing downlink transmission to mobile ground users, the study places particular emphasis on the role of LiFi as a complementary physical layer technology within heterogeneous networks—an aspect closely connected to optical and photonics advancements. The proposed system is designed for environments such as theme parks and public events, where user groups move collectively toward points of interest (PoIs). To maintain quality of service (QoS) under dynamic mobility, we develop a joint optimization framework that simultaneously designs the UAV’s flight path and resource allocation over time. Given the problem’s non-convexity, a block coordinate descent (BCD) based approach is introduced, which decomposes the problem into power allocation and path planning subproblems. The power allocation step is solved using convex optimization techniques, while the path planning subproblem is handled via successive convex approximation (SCA). Simulation results demonstrate that the proposed algorithm achieves rapid convergence within 3–5 iterations while guaranteeing 100% heterogeneous QoS satisfaction, ultimately yielding nearly 15.00 bps/Hz system capacity enhancement over baseline approaches. These findings motivate the integration of coordinated three-dimensional trajectory planning for multi-UAV cooperation as a promising direction for further enhancement. Although LiFi is implemented in free-space optics rather than fiber-based sensing, this work highlights a relevant optical technology that may inspire future cross-domain applications, including those in optical sensing, where UAVs and reconfigurable optical links play a role.

Urban parks provide critical benefits for public health, mental well-being, and social connection. However, inequities in park access and use persist, particularly among socially and economically vulnerable populations. While previous studies have established that segregation and social vulnerability each contribute to uneven park access, little is known about how these two forces interact to shape real visitation patterns. This study addresses this research gap and answers the research question: How does highway segregation relate to differences in the different aspects of social vulnerability in influencing park access across Austin’s east–west divide? SafeGraph mobility data from 2019 and the Social Vulnerability Index (SVI), which included four themes (i.e., socioeconomic status, household composition, minority status and language, and housing and transportation characteristics), were analyzed through fixed-effects regression models for Austin, Texas. Results show that household composition and minority vulnerabilities have negative associations with park visitation, indicating that areas with more elderly, single-parent, or minority residents visit parks less frequently. Interaction terms reveal that highway segregation functions as a structural barrier that conditions the influence of social vulnerability on park use. Those associated with socioeconomic resources diminish, while the disadvantages linked to household composition and minority status intensify on the east side of I-35, reflecting the cumulative effects of segregation and infrastructural division. These findings confirm that inequities in park access are more pronounced on the east side of the I-35, consistent with the highway’s role in reinforcing segregation. Efforts to strengthen connectivity represent key strategies for advancing equitable park visitation across Austin. Full article

This study investigates the potential of creative tourism in Thailand’s national parks and the role of social media in promoting creative tourism experiences. The objectives were to examine creative tourism activities, identify visitor segments based on activity preferences and media use, and propose targeted communication strategies to enhance engagement and support sustainable tourism. A mixed-methods design combined document reviews of 133 national parks, field surveys in 10 parks, and a structured visitor survey with 1133 respondents across terrestrial and marine parks. The study identified 25 tourism activities, of which 20 were classified as creative tourism. Exploratory Factor Analysis revealed four key dimensions: nature-based learning, scenic immersion, community participation, and culinary experiences. Cluster analysis segmented visitors into five groups: Local Advocates, Nature Explorers, Food Enthusiasts, Nature Learners, and Diverse Enthusiasts. Media preferences varied across groups. Nature Explorers and Food Enthusiasts engaged strongly with short-form videos and scenic visuals, while Local Advocates and Nature Learners preferred educational and text-based formats. Diverse Enthusiasts, the largest segment, interacted with multiple content types. Scenic imagery emerged as the most influential theme overall. These results provide practical implications for designing creative tourism strategies and creating social media campaigns to diverse groups of tourists in Thailand’s national parks. Full article

Renewable energy systems in the Industry 4.0 era have maintenance and production maximization as their central element, depending on the type of source. For solar panels, achieving these goals requires periodic cleaning of dust deposits. This research integrates the detection of dust particles on solar panels using classification models based on machine learning models integrated into the Azure platform. However, the main contribution of the work does not lie in the development or improvement of a classification model, but in the design and implementation of an Internet of Things (IoT) hardware–software infrastructure that integrates these models into a complete predictive maintenance workflow for photovoltaic parks. The second objective focuses on how the identification of dust particles further generates alerts through a centralized platform that meets the needs of Industry 4.0. The methodology involves analyzing how the Azure Custom Vision tool is suitable for solving such a problem, while also focusing on how the resulting system allows for integration into an industrial workflow, providing real-time alerts when excessive dust is generated on the panels. The paper fits within the theme of the Special Issue by combining digital technologies from Industry 4.0 with sustainability goals. The novelty of this work lies in the proposed architecture, which, unlike traditional IoT approaches where the decision is centralized at the level of a single application, the authors propose a distributed logic where the local processing unit (Raspberry Pi) makes the decision to trigger cleaning based on the response received from the cloud infrastructure. This decentralization is directly reflected in the reduction in operational costs, given that the process is not a rapid one that requires a high speed of reaction from the system. Full article

Urban parks are vital public spaces that provide opportunities for recreation, relaxation, and social interaction. At night, their accessibility and functionality depend strongly on the quality of artificial lighting, which must balance user safety and comfort with ecological sustainability. This study investigates public perceptions of urban park lighting through a mixed-method approach combining participatory workshops and surveys. A workshop (n = 15), involving local residents recruited through community networks, included introductory presentations, group discussions, and open voting to map the related problems in the park activities. Data were collected through participant notes, visuals, and sketches. In parallel, an online and on-site survey (n = 144) was distributed via Google Forms during winter 2025. Results reveal three main themes. First, users consistently emphasized safety and orientation as the most critical functions of park lighting, though the 52.5% perception of safety remained moderate even in lit areas. Second, respondents and workshop participants expressed a preference for adaptive, functionally targeted lighting over uniform illumination. Third, ecological awareness was evident as more than half of the respondents recognized the negative effects of artificial lighting on the natural environment, with strong support for warm-spectrum lighting and light zoning to protect biodiversity. These findings highlight the potential of participatory methods to inform evidence-based, ecologically sensitive lighting strategies for urban parks. Full article

The aim of conversion is to reveal the potential of non-functioning buildings for transformation—i.e., to design a new life for them. A large number of original and presently non-functioning industrial production buildings are connected to mining activity. The subject of this study and area of investigation are selected mining networks from the second half of the 20th century in the Rudňany settlement, which is located in the Spiš region. The aim of the research is to form a process algorithm for the reuse of areas and objects of mining activity and to highlight the cultural values, constructional substance, and preconditions for their further development. Part of the investigation comprises proposals for a new functional usage of the structures that will encompass the complex historical ground-points of the locality and include its historical roots and trends in the region’s social development and community. The quantitative and qualitative research is based on an analysis of the values of such structures based on traditional mining activity, accompanied by landscape research of the specific locality. The results are presented in the form of case studies oriented towards the identification and evaluation of the attributes of change for novel exploitation of the mining sites. The conclusion of the research is composed of an evaluation and interpretation feasibility study pointing out suitable solutions and preconditions for the sustainability of the converted mining structures as parts of open concepts for mining theme parks.

Water resources allow us to trace the history of many of our towns. In settings with limited surface water, a very interesting case study is represented by the presence/preservation of water in the rupestrian towns located along the rocky walls of canyons (locally named “gravine”) southward, cutting the Murge karst area (Puglia, Southern Italy). In some sections of their valleys, soft rocks, easy to dig, are exposed, and, along the canyon flanks, favored the development of rupestrian towns (cities where dwellings are carved in these soft rocks). Here, before the construction of aqueducts that now bring water from the “distant” Apennines (at least 30 km away), the building of historical fountains, in addition to the collection of rainwater in cisterns, testifies to the presence of an aquifer now undervalued as a local water resource useful for human settlements in a predominantly karst territory. Our study regards an aquifer feeding the Mascheroni Fountain (Great Masks Fountain) through a short qanat that allowed for the development of the old town of Laterza, in Puglia (Southern Italy). Starting from the attractiveness of the ancient fountain, the connection between geological features of the area and the ancestral origin of the city could be proposed to a large audience, representing an intriguing opportunity to develop themes useful for geotouristic purposes and disseminating concepts about sustainability and the importance of preserving local renewable resources. This topic is of paramount importance since the town of Laterza is located at the boundary between the UNESCO MurGEopark and the “Terra delle Gravine” Regional Park, making it the ideal starting point for both parks.

Over the last decade, the scientific community has increasingly focused on forest-based practices for human well-being (FBPW), a term that includes all forest activities (e.g., forest bathing, forest therapy, social outdoor initiatives) important for improving people’s health and emotional status. This paper aims to develop a quantitative literature review on FBPW based on big data analysis (text mining on Scopus title and abstract) and PRISMA evaluation. The two techniques facilitate investigations across different geographic areas (major areas and geographical regions) and allow a focus on various topics. The results of text mining highlight the prominence of publications on FBPW for the improvement of human health in East Asia (e.g., Japan and South Korea). Furthermore, some specific themes developed by the literature for each geographical area emerge: urban green areas, cities, and parks in Africa; sustainable forest management and planning in the Americas; empirical studies on physiological and psychological effects of FBPW in Asia; and forest management and FBPW in Europe. PRISMA indicates a gap in studies focused on the reciprocal influences of forest variables and well-being responses. An investigation of the main physiological indicators applied in the scientific literature for the theme is also developed. The main strengths and weaknesses of the method are discussed, with suggestions for potential future lines of research. Full article

Before the onset of global warming concerns, the idea of manufacturing electric vehicles on a large scale was not widely considered. However, electric vehicles offer several advantages that have garnered attention. They are environmentally friendly, with simpler drive systems compared to traditional fossil fuel vehicles. Additionally, electric vehicles are highly efficient, with an efficiency of around 90%, in contrast to fossil fuel vehicles, which have an efficiency of about 30% to 35%. The higher energy efficiency of electric vehicles contributes to lower operational costs, which, alongside regulatory incentives and shifting consumer preferences, has increased their strategic importance for many vehicle manufacturers. In this paper, we present a thematic literature review on electric vehicles charging station location planning and scheduling. A systematic literature review across various data sources in the area yielded ninety five research papers for the final review. The research results were analyzed thematically, and three key directions were identified, namely charging station deployment and placement, optimal allocation and scheduling of EV parking lots, and V2G and smart charging systems as the top three themes. Each theme was further investigated to identify key topics, ongoing works, and future trends. It has been found that optimization methods followed by simulation and multi-criteria decision-making are most commonly used for EV infrastructure planning. A multistakeholder perspective is often adopted in these decisions to minimize costs and address the range anxiety of users. The future trend is towards the integration of renewable energy in smart grids, uncertainty modeling of user demand, and use of artificial intelligence for service quality improvement. Full article

This study employs Hannah Arendt’s (1958) the human condition as a philosophical framework to examine walking not merely as a physical activity but as a meaningful form of environmental consciousness. Homo faber, which denotes tool making, corresponds to the nature-based railway regeneration exemplified by the Gyeongui Line Forest Park in Seoul City, South Korea. By applying walking as a method, bifurcated themes are explored: a pedestrian-provision focus on walkability and an environmentally oriented focus consisting of nature and culture, supporting the notion that environmental elements are co-experienced through the embodied activity of walking. Thematic findings are supported by generalized additive models, grounded in a between-method triangulation attempt. The results confirm the interdependencies among the park’s environment, pedestrian satisfaction, and environmental consciousness. Specifically, the environment surrounding the park, which traverses natural and cultural elements, is strongly associated with both pedestrian satisfaction and environmental sensitivity. The research reifies walking as a fundamental human condition, encompassing labor, work, and action, while arguing for heuristic reciprocity between homo faber and nature, as well as framing walking as a sustainably meaningful urban intervention. This study contributes to maturing the theoretical understanding of walking as a vital human condition and suggests practical insights for pedestrian-centered spatial transformation. Full article

The COVID-19 pandemic and its associated lockdowns had widespread psycho-social implications globally. However, the unique experiences of young adults in under-researched rural communities, such as Lonely Park in South Africa’s North West Province, remain poorly documented. This study explores the psycho-social well-being of young adults aged 18–24 in the Lonely Park community during the national COVID-19 lockdown from 23 March 2020 to 30 April 2020, with a particular focus on their emotional, psychological, and social experiences. Using a qualitative, phenomenological design rooted in Bronfenbrenner’s Ecological Systems Theory (EST), data were collected from 14 purposively sampled participants through two focus group discussions. Thematic analysis was conducted following Braun and Clarke’s six-phase framework. Ethical clearance was obtained from the Health Research Ethics Committee, and participants provided informed consent. Two main themes emerged, (1) psychological and (2) social well-being. Six sub-themes were identified: (1) negative emotions linked to lockdown, (2) fear of COVID-19 and its consequences, (3) rumination and anxiety, (4) disruption of social and educational routines, (5) coping strategies, and (6) structural limitations of healthcare and support systems. Participants experienced intense fear, boredom, isolation, and a sense of helplessness. Yet, coping mechanisms such as communication, spirituality, exercise, and adherence to public health regulations provided resilience. Some reported depression and financial strain due to job loss and school disruptions. The findings highlight the complex interplay of psychological, emotional, and social stressors in rural young adults during the pandemic. Policymakers and mental health practitioners must prioritise targeted psycho-social interventions for youth in under-resourced rural settings. A call is made for culturally responsive mental health programmes that incorporate local voices, especially in rural African contexts. Full article

The rise of knowledge-based economies has positioned higher education institutions as key actors in human capital development, requiring them to engage more actively with labor markets through strategic partnerships. Within this context, university-affiliated science and technology parks (STPs) have evolved into integrated learning environments that support experiential learning and mentorship practices. This study aims to explore the lived experiences of undergraduate students who participated in these processes within an STP in İstanbul, Türkiye. Using a qualitative phenomenological approach, data were collected through semi-structured interviews with 15 students selected via purposive maximum variation sampling. Thematic analysis, supported by MAXQDA 2024, was used to examine the data. Two main themes were identified: (i) talent development through experiential learning and (ii) talent development through mentorship. The findings indicate that students reconstructed theoretical knowledge through real-world applications, developed a clearer professional identity, and gained strategic career awareness. Mentorship provided both technical and psychosocial support, fostering self-confidence, emotional security, and role modeling. This study concludes that STPs play a strategic role in aligning academic learning with employability and institutional talent development goals. These results contribute to broader educational and workforce development discussions and are closely aligned with Sustainable Development Goals 4 (Quality Education) and 8 (Decent Work and Economic Growth), highlighting STPs as transformative platforms in higher education. Moreover, this study offers practical implications for aligning higher education with employment systems through structured experiential learning and mentorship practices. Full article

Systematically synthesizing existing knowledge on ecological resettlements (ERs) is crucial for shaping future research and conservation strategies. We conducted a systematic literature review (SLR) using the Web of Science and Scopus databases, analyzing 63 research articles in the review domain of ER. Most reviewed articles emphasize people’s welfare in ERs but adopt traditional review approaches, hindering the identification of specific research gaps. This review identifies and focuses on four cross-cutting themes: anthropocentric notions and social equity, parks–people relationships, political ecology and biodiversity conservation, and connecting nature with people for harmonious coexistence. Further, the review highlights key themes in ER and conservation, emphasizing social equity, political ecology, and human–nature relationships. It underscores the need for social justice, the recognition of displaced communities’ rights, and the promotion of participatory decision making. Conservation efforts should prioritize minimizing displacement and respecting local rights, with a focus on co-management models. Case studies, particularly from India and African countries, reveal the impacts of conservation-induced displacement on marginalized communities and ecosystems. Further, we identified 45 key areas across 15 thematic dimensions for future review and research gaps, which will inform decision making in the discipline. We call for long-term assessments of resettlement to address ecological and social consequences, bridging the gap between social scientists and biologists for balancing conservation and human welfare. Finally, we discuss our findings and propose future research directions to inform conservation policies for the harmonious coexistence of humans and non-human beings on a shared planet. Full article

Urban parks serve as essential carbon sinks in cities, mitigating climate change by sequestering atmospheric CO₂. Maximizing the carbon sequestration potential within constrained urban spaces is a critical step toward carbon neutrality. However, few studies have systematically examined how the internal spatial composition and shape of green spaces affect their vegetation carbon sequestration capacity. This study analyzes the relationship between landscape indices and vegetation carbon sequestration density (VCSD) using field surveys and high-resolution remote sensing data from 123 urban parks in Zhengzhou, China. The results indicate that Zhengzhou’s parks sequester 14.03 Gg C yr⁻¹, with a VCSD of 0.53 kg C m⁻² yr⁻¹. Significant differences in VCSD were observed among park types, with theme parks having the highest average VCSD (0.69 kg C m⁻² yr⁻¹) and community parks the lowest (0.43 kg C m⁻² yr⁻¹). The key drivers primarily consist of landscape indices that characterize green space distribution and configuration, including the proportion of green space (Pg), largest green patch index (LPI), number of green patches (NP), green patch dispersion index (SPL), and landscape shape index (LSI), with specific thresholds identified for each. Based on these findings, category-specific spatial composition strategies are proposed to precisely enhance the carbon sequestration of park vegetation. This study provides actionable guidance for urban park designers to maximize the carbon sequestration potential of green spaces, thereby mitigating climate change and promoting human health and well-being through green space design.
