The soundscape serves as a critical determinant of the quality of urban wetland parks. This study employs a mixed-methods approach to comprehensively evaluate wetland soundscapes. First, field investigations combining sound level measurements and questionnaire surveys were conducted in Aixi Lake Wetland Park to analyze the spatiotemporal characteristics of the soundscape. Second, laboratory-based physiological tracking (using wearable sensors) and cognitive tests (Sustained Attention to Response Task, SART) were utilized to experimentally quantify the restorative benefits of typical soundscapes. The findings reveal that: (1) sound level indicators and sound harmonious degree in urban wetland parks exhibit significant spatiotemporal characteristics and distributional variations; (2) a marked competitive effect among biological, geophysical, and human activity sounds is observed in their spatial distribution; sound harmonious degree demonstrates significant spatial autocorrelation in both global and local models; (3) different sound sources possess varying restorative potentials, with bird song showing the highest restorative effect; the SHDs of biological and geophony, along with L_Aeq, are key factors affecting PRSS; (4) a positive correlation exists between L_Aeq and the PRSS up to 56.4 dB, beyond which PRSS declines with increasing L_Aeq; (5) at the physiological level, short-term exposure to urban wetland park soundscapes can rapidly alleviate stress, with the most pronounced restorative effects occurring within the first 60 s; and (6) in terms of attention, soundscape stimulation reduces SART response times and improves response speed, while bird song from treetops and musical sounds further decrease response errors.

Air pollution is one of the major environmental challenges threatening global sustainable development and human health. The World Health Organization identifies it as a critical factor contributing to non-communicable diseases and inequality, especially in vulnerable populations such as children. The findings highlight the negative effects of environmental degradation on physical health and underline the urgent need to incorporate health metrics, such as children’s fitness, into sustainability monitoring frameworks and public policies aiming at cleaner and healthier urban environments. The aim of this study was to examine the association between ambient particulate pollution and cardiorespiratory fitness in school-aged children from two rural villages in southern Spain characterised by relatively higher and lower levels of particulate matter. A total of 938 children (primary and secondary school levels) participated in a naturalistic pre–post study design. Cardiorespiratory fitness was assessed using the 6 min walk test, where maximal oxygen uptake (VO₂max) was estimated. Assessments were conducted before and after a period characterised by unfavourable air-quality conditions in the higher-pollution village. The students were assigned by convenience into an experimental [n = 476 (EG)] and a control group [n = 462 (CG)]. The t-test, repeated measures analysis and MANOVA test were used in order to report differences within and between groups, as well as time-points and academic levels. The significance level was set at p < 0.05. Significant differences between groups were reported within the pre-test period, showing elevated pre-test values in the CG compared to the EG. The EG showed a higher pre–post difference in estimated VO₂max compared to the CG for primary education level (16.19%, ES(d) = 0.91 vs. 3.07%, ES(d) = 0.26; p < 0.001, respectively); secondary education (EG: 12.29%, ES = 0.91 vs. CG: 1.69, ES(d) = 0.16); and the whole population (EG: 14.72%, ES = 0.91 vs. CG: 2.84, ES = 0.25). It seems that the environmental context, and specifically the air pollution in the area of residence, may be an important factor to consider in relation to the assessment of physical fitness in the school-aged youth population.

Effective incident management is a cornerstone of transportation system performance, influencing roadway clearance times (RCTs) and the risk of secondary crashes. This study investigated how towing regulations involving large commercial vehicle crashes and jurisdictional variations affect the management of large-vehicle crashes, focusing on the relationship between regulatory frameworks, incident duration, and secondary crash occurrence with the state of Tennessee as a case study. The objective was to determine whether differences in towing policies, operational mandates, and rural/urban contexts lead to measurable changes in clearance efficiency. A multi-year dataset of more than 770,000 traffic incidents and 4400 towing-involved large-vehicle crashes from 2017 to 2022 was analyzed. Statistical methods, including two-sample testing and hazard-based survival modeling, were applied to evaluate the impact of towing regulations and operational protocols on roadway clearance and secondary crash patterns. The results consistently showed that strong performance-based towing regulations, such as mandated maximum response times and standardized training and equipment requirements, were associated with significantly lower average RCTs. Jurisdictions with enforced rapid-response mandates achieved average clearance durations of approximately 120–130 min, even under high incident volumes, compared to over 150 min in areas without performance benchmarks or with more complex procedural requirements. A pronounced rural–urban divide was observed, with incidents outside urbanized areas averaging 30–40% longer clearance times, largely due to limited towing resources, longer dispatch distances, and less stringent regulatory enforcement. Secondary crash analysis identified that more than 90% of secondary collisions were linked to crashes requiring towing, with the majority occurring within 20 min and 0.5 miles of the primary incident, underscoring the direct connection between delayed clearance and safety risk. These results carry direct implications for transportation policy and incident management practice by providing empirical evidence that standardized, performance-based towing regulations can meaningfully reduce RCTs and secondary crash risk, particularly when paired with investments in rural towing infrastructure Full article

The resource utilization of construction and demolition waste (CDW) is crucial for advancing the green transformation of the construction industry, but it faces challenges such as insufficient upstream R&D motivation and low downstream market acceptance. To investigate the impact of corporate social responsibility (CSR) and sales effort on the recycled cement supply chain, in this study, a Stackelberg game model of a two-tier supply chain comprising a single recycled cement manufacturer and retailers is constructed. Under government subsidy conditions, four CSR sharing modes are systematically compared: no CSR (NS), manufacturer-borne (MS), retailer-borne (RS), and shared by both (TS). The results indicate the following: (1) CSR implementation reduces wholesale and retail prices while increasing sales effort, the incorporation rate of recycled aggregates, and market demand, with retailers bearing CSR yielding the most significant pull effect; (2) heightened sensitivity to sales effort incentivizes retailers to increase sales investment and encourages manufacturers to increase the incorporation rate of recycled aggregates, thereby increasing overall supply chain profits and utility; and (3) when the CSR coefficient does not exceed the critical value of 0.97, both manufacturer profits and retailer profits increase as the CSR level increases under the TS model; under the RS model, total supply chain profits and total utility reach their maximum. Corporate social responsibility (CSR) undertaken or jointly undertaken by retailers can better align economic and social objectives. This study provides theoretical foundations and practical insights for policy formulation and corporate decision-making in construction waste resource management. Full article

Tourism has become a structural driver of land-system transformation, influencing urban restructuring, rural land consumption, coastal development, and housing dynamics. Although tourism sustainability has received growing scholarly attention, less systematic evidence exists on how land governance and spatial planning frameworks mediate tourism-related land-use change. This study presents a systematic review of peer-reviewed journal articles published between 2000 and 2025 examining the relationship between spatial planning, land-use regulation, and tourism development. Following PRISMA guidelines, a structured search strategy and multi-stage screening process were applied using predefined inclusion and quality criteria, resulting in a final dataset of 58 studies. The findings indicate that tourism-driven land transformation is shaped by interconnected governance layers, including statutory planning instruments, institutional coordination mechanisms, and land administration infrastructures. However, these dimensions are rarely analyzed within an integrated framework. By synthesizing tourism planning and land administration scholarship through a land governance perspective, this review clarifies how regulatory tools and administrative systems interact in shaping spatial outcomes across scales. The study offers a structured basis for future comparative research and for more coherent policy responses to tourism-related land governance challenge. Full article

Early-stage remote site analysis is often hindered by fragmented media that fail to convey sufficient spatial context to off-site collaborators. To address this challenge, we propose SiteSync, a real-time remote collaborative system that combines live video, coarse mesh streaming, georeferenced pose tracking, and 3D spatial annotations to establish a shared spatial understanding between on-site and remote collaborators. The system was evaluated through a counterbalanced within-subject study with 24 participants, comparing the synchronous SiteSync workflow against a traditional asynchronous baseline. The results showed that SiteSync significantly improved task performance by reducing completion time and rework while increasing overall accuracy (all p < 0.001). Participants also reported lower cognitive workload and higher usability. Remote users benefited most significantly. These findings show that the synchronous workflow can improve collaboration efficiency and user experience in early-stage site analysis. Full article

The purpose of this instrumental case study, employing both qualitative and quantitative data, was to investigate how novice teachers from non-local and urban areas used community assets and local funds of knowledge (FoK) in their STEM instruction in a remote Montana town. While non-local teachers often make up a large share of many rural communities’ teaching workforce, those teachers might lack the social, cultural, and community knowledge that they need to teach with place-conscious approaches. Therefore, this study explored how “new-to-town” teachers, with limited personal ties to a community, learn about their rural community and how they apply this knowledge to their teaching context. Additionally, this study examined which research-established factors that improve rural STEM education were deemed most important for novice, rural teachers. The exploration employed a floodlight research approach, whereby a census of the authentic pedagogical actions of the subjects was documented rather than investigating the efficacy of a single method. Data sources included qualitative instruments like concept maps and semi-structured interviews, alongside quantitative measures like ranked best-practices data and place-conscious lesson ratios, to provide both depth of interpretation and breadth of comparison across participants. Results from the deductive thematic analysis suggest that novice teachers aspire to implement asset-based pedagogical approaches in STEM instruction and possess some methods for integration but struggle to learn of local community assets without modeling and mentorship. Additionally, an unexpected pattern emerged from the findings: Novice, newcomer teachers that employed place-conscious lessons were more likely to remain teaching in their position. While this association cannot be interpreted causally, it might suggest that place-conscious mentorship practices may play a role in improving instruction and support the retention of non-local teachers in rural communities however, further, more robust exploration is warranted of this exploratory finding. Findings from this study can be used to inform recommendations for school districts, post-secondary institutions, and rural communities on how best to support beginning rural teachers with limited community connections.

The Historic Urban Landscape (HUL) approach provides a vital and extensive framework for heritage conservation. However, local practices often struggle to spatially translate qualitative assessments into quantitative controls at the urban block level, the most effective basic scale for administrative implementation, thereby limiting effective responses to the Management of Change. By integrating HUL with the theory of Dynamic Integrity, this study constructs a multi-dimensional evaluation index system and proposes a HUL evaluation method based on Character-Based Zoning. Taking the 125 urban block units of the historic urban area of Jingdezhen as a case study, this research integrates historical mapping, GIS spatial analysis, and Co-occurrence Network Analysis to reveal the internal structural logic of the heritage system. The study finds that the HUL of Jingdezhen is a multi-nodal dynamic system driven by four core elements: ritual beliefs, administrative management, production activities, and commercial guilds. Critically, modern visual intrusions severely impact the core heritage components within this system, specifically the Dubang and ritual culture. Based on the three dimensions of Heritage Richness, Landscape Sensitivity and Value Centrality, the study systematically identifies a total of 11 types of urban block units within the plots that characterize distinct historic landscape features and transformation patterns. This research not only deepens the localized application of HUL theory but also provides a scientific basis and methodological support for the Management of Change and periodic assessment in dynamic heritage environments.

Urban floods have become a major systemic risk to sustainable urban development under climate change and increasingly frequent extreme hydro-meteorological events. Yet evidence on the long-term evolution of urban flood resilience (UFR) and its structural constraints at the provincial scale remains limited. This study develops a PSR-based framework to assess UFR and diagnose its dominant obstacles using data for 21 prefecture-level cities in Sichuan Province from 2011 to 2023, including meteorological, geomorphological, socioeconomic, infrastructure, environmental, and public service indicators. A combined AHP–EWM is used to integrate subjective and objective information, TOPSIS is applied to derive a composite UFR index and subsystem scores, and an obstacle degree model is employed to identify key constraints and their temporal evolution. Results show that: (1) UFR in Sichuan Province fluctuated but increased overall during 2011–2023, reaching its highest level in 2023; (2) resilience improvement was driven mainly by the response subsystem, while the pressure subsystem showed the greatest interannual variability; and (3) the annual top five obstacles were highly persistent and insufficient response capacity was the dominant long-term constraint on resilience enhancement. These findings underscore that improving the adequacy, institutional robustness, and operational stability of response systems is central to enhancing UFR. This study provides empirical support for the assessment of provincial-scale resilience and policy-oriented flood risk governance. Full article

In recent decades, the Ucayali region, the main territory of the Asheninka communities, has experienced increasing socio-environmental pressures associated with climate change, educational inequality, and territorial vulnerability in rural and indigenous contexts. In response, this research proposes the design of a sustainable agricultural school for the Asheninka community, conceived as an educational building that integrates biophilic strategies to enhance environmental performance and spatial quality. The methodological approach comprises a literature review, site-specific environmental analysis based on hydrometeorological data, and the development of an architectural proposal focused on sustainable building design. Digital tools such as Revit and SketchUp were employed alongside official climatic data sources to support design decision-making. The proposal includes twelve biophilic agricultural classrooms incorporating passive design strategies, rainwater harvesting systems with a capacity of 22.5 m³ per day per classroom, and photovoltaic-powered public lighting systems. Results indicate that the integration of natural ventilation, green infrastructure, and locally sourced materials contributes to significant improvements in thermal comfort, humidity control, and energy autonomy within the educational facilities. The architectural complex is complemented by green corridors and collective open spaces that reinforce environmental performance at the site scale. This study demonstrates that sustainable educational buildings adapted to local ecosystems and climatic conditions can function as effective infrastructures for environmental mitigation and resilient rural development, contributing to more sustainable forms of urban and rural living.

Demand for camel milk products is growing in Morocco and worldwide, creating opportunities to strengthen the livelihoods of populations living in arid regions through the development of camel-based dairy value chains. In addition to their economic potential, such value chains may contribute to sustainability by supporting food systems adapted to arid environments, promoting the use of locally resilient livestock species, and enhancing the socio-economic viability of vulnerable rural communities. This exploratory qualitative study investigates urban consumer behavior related to dairy consumption with a specific focus on the potential integration of camel milk products into local dietary habits. To capture nuanced consumer perspectives, gender-segregated focus-group discussions were conducted in three Moroccan cities using a semi-structured questionnaire on dairy consumption habits. Key factors examined included milk types, product preferences, purchasing locations, consumption frequency and willingness to include camel products in the household diet. The results indicate that camel milk is rarely consumed outside areas where camels are raised. Nevertheless, participants expressed interest in several camel milk-based products, particularly fermented milk and spreadable cheeses. This interest was primarily driven by perceptions of camel milk as a healthy product and by its association with traditional food practices. These findings suggest that expanding camel milk consumption in urban markets could support more sustainable and territorially rooted dairy systems by linking consumer demand with production models suited to dryland conditions. This study indicates promising market opportunities for the development of camel milk products in urban areas, particularly if challenges related to pricing strategies, distribution network, and region-specific supply chains are strategically managed.

Examining the effect of digital village construction (DVC) on agriculture–culture–tourism integration (ACTI) is important for understanding sustainable rural development. Using panel data from 30 Chinese provinces from 2012 to 2022, this study employs a two-way fixed-effects model to examine the impact of DVC on ACTI, along with its mediating mechanisms and heterogeneous effects. Results show a significant inverted-U-shaped relationship between DVC and ACTI. This finding remains robust across a series of tests. Mechanism analysis reveals that industrial structure upgrading and urbanization play partially mediating roles with the same inverted-U-shaped characteristics. Heterogeneity analysis indicates that DVC presents a linear positive effect in central and western regions and in areas with low DVC levels, while an inverted-U-shaped pattern is observed in eastern regions and in areas with high DVC levels. These findings suggest that DVC strategies should account for both regional differences and development stages. Full article

Digital urban–rural sharing of social public resources (SPRs) is important for improving resource allocation efficiency and narrowing urban–rural disparities. This study applies a tripartite evolutionary game framework to analyze the strategic interactions among the government sector, the sharing supply side, and the sharing demand side in the digital urban–rural SPR sharing process. A system dynamics (SD) model is further constructed to simulate the dynamic evolution of the system under different initial conditions and parameter settings. The results show that the system generally evolves along a path of government initiation, demand-side response, and supply-side follow-up. Higher collaborative benefits, lower resource transfer costs, stronger government credibility, and appropriately designed subsidies promote active sharing and accelerate convergence toward a high-sharing stable outcome. In contrast, high transfer costs, weak collaborative incentives, and insufficient regulatory credibility inhibit sharing behavior or delay convergence. In addition, different initial cooperation levels mainly affect the convergence speed and fluctuation pattern of the evolutionary process. This study extends the application of the tripartite evolutionary game framework to the digital urban–rural SPR sharing context and combines it with SD simulation to reveal the system’s dynamic evolution mechanism. The findings provide practical implications for promoting digital urban–rural SPR sharing through moderate subsidies, reduced transfer costs, enhanced regulatory credibility, and strengthened collaborative mechanisms.

The platformization of urban space is opening new frontiers of capital accumulation, particularly through short-term rentals. Airbnb plays a central role in this process by commodifying housing in tourist destinations. Despite its rapid growth, research on Airbnb in Latin America—especially in small tourist cities—remains limited and largely focused on metropolitan contexts. This article addresses this gap with the objective of analyzing how platform-mediated short-term rentals reorient housing markets beyond traditional urban cores. It is hypothesized that Airbnb expands housing commodification by extending tourism-oriented uses into new residential areas and by redistributing returns unevenly across actors. Using a quantitative and geospatial approach, the results reveal a strong presence of Airbnb in rural and natural areas, from which the highest returns are extracted, as well as a high concentration of accommodation supply among professional hosts. These dynamics reconfigure housing use toward asset-based logics, posing challenges for housing security and social and territorial sustainability in small tourist cities. Full article
