Provincial cold-chain investment decisions must reconcile food-loss prevention, digital visibility, logistics capability and the environmental burden of freight-intensive growth. This study develops a sustainability-oriented readiness–intensity framework for 31 provincial-level regions in mainland China. The baseline model uses 14 auditable public-data criteria and combines Criteria Importance Through Intercriteria Correlation (CRITIC) with the standard Combined Compromise Solution (CoCoSo) algorithm. Because the observations combine 2024 statistics, a 2023 digital-finance index and the cumulative 2020–2025 cold-chain-base list, the design is described as an asynchronous cross-sectional snapshot rather than a single-year panel. Municipal sewage and green-space variables are interpreted as regional enabling capacity, not direct cold-chain environmental performance; road freight turnover relative to gross domestic product is treated as a cost-type freight-intensity transition-pressure proxy. A separate diagnostic replaces the earlier inverse-size term with logistics residuals conditional on agri-food output. Shandong, Guangdong, Jiangsu, Henan and Zhejiang form the leading demonstration-readiness group. Equal-weight CoCoSo closely matches the CRITIC result (Spearman ρ = 0.996), while TOPSIS and VIKOR retain the broad ordering but expose local method sensitivity. Dropping either digital criterion, removing the three indirect green proxies, winsorizing the normalization range, varying the CoCoSo compromise parameter and substituting 2022 digital data do not alter the leading pattern. Under an assumed 5% indicator-error perturbation, Shandong and Guangdong remain within ranks 1–2, whereas the ordering of several adjacent provinces is less secure. The framework supports sequenced investment packages rather than a deterministic league table and distinguishes demonstration-ready, scale-led, intensity-led and coverage-building contexts.

The development of arid-oasis agriculture and territorial spatial restructuring strongly influence regional eco-environmental quality. Clarifying production–living–ecological space (PLES) transitions and the nonlinear mechanisms driving eco-environmental quality is important for sustainable agricultural land use and ecological governance. Northern Xinjiang combines economic agglomeration with ecological sensitivity, making it a representative region for examining changes in eco-environmental quality and their underlying drivers. Land-use data for 1990, 2000, 2010, and 2020 were analyzed using land-use transition matrices, the eco-environmental quality index (EEQI), spatial autocorrelation, and hotspot analysis to characterize spatiotemporal changes under PLES transitions. XGBoost–SHAP was applied to identify the dominant factors, nonlinear responses, and interactions. The results showed that: (1) ecological space remained dominant from 1990 to 2020, but its share declined from 91.72% to 87.36%. Production and living spaces increased from 7.78% and 0.50% to 11.72% and 0.92%, respectively. Agricultural production space expanded most markedly, and spatial restructuring was most intense during 2000–2010. (2) EEQI decreased from 0.3100 to 0.2922 and showed an overall fluctuating decline. Significant spatial clustering was observed, with Moran’s I values consistently above 0.81 (p < 0.001). High-value areas were mainly distributed in the Ili River Valley and along the northern slope of the Tianshan Mountains, whereas low-value areas were concentrated in the Junggar Basin interior and the arid areas along its eastern margin. (3) During 2000–2020, LAI and NPP in agricultural production space increased by 45.7% and 48.2%, respectively. These increases indicated overall improvements in canopy condition and productivity. After 2010, NPP growth slowed markedly while LAI remained relatively stable, indicating a stage-specific divergence. (4) XGBoost–SHAP showed good robustness and spatial generalizability, with R² values of 0.868–0.918 and RMSE values of 0.059–0.075. NDVI remained the primary driver, while Elev contributed consistently. The dominant interaction shifted from NDVI ∩ PopDen in 1990 and 2000 to NDVI ∩ Elev in 2010 and NDVI ∩ GDP in 2020. This shift indicated fundamental natural constraints and stronger joint effects of population and economic activities during the later stages. These findings provide a scientific basis for optimizing PLES, regulating arid-oasis agriculture, and safeguarding regional ecological security. Full article

Agriculture faces the challenge of transitioning toward sustainable practices, driving the use of plant growth-promoting bacteria (PGPB). However, these bacteria suffer critical losses in viability due to environmental stress and drying processes. Although synthetic hydrogels offer protection, their low biodegradability and toxicity pose ecological risks, positioning dextran hydrogels produced by Leuconostoc sp. as a biocompatible biotechnological alternative, despite challenges related to their mechanical stability. The methodology employed consisted of systematic literature mapping in the Scopus database for the period 2010–2026. The search was conducted on 2 May 2026, using a defined search equation, and 447 documents were processed using RStudio (Bibliometrix), VOSviewer, and Plotly Studio to analyze trends and collaboration networks. The results of the systematic mapping reveal an exponentially growing field (R² = 0.998), led by Agricultural Sciences (23.5%) and Biochemistry (16%). China and India dominate scientific output in terms of volume, while Italy and the United States lead in qualitative impact, with researchers such as Cimini, Schiraldi, and Pandey as key references. An evolution is confirmed from the basic characterization of Leuconostoc sp. toward the development of matrices for immobilizing PGPB, reducing viability losses from 6 log to manageable levels of 4 log CFU. Cluster analysis shows a clear trend toward nanotechnology and “smart hydrogels” responsive to multiple stimuli. Finally, strategic gaps were identified in the creation of predictive release models, as well as an urgent need to democratize the technology through low-cost processes, essential aspects for consolidating sustainable precision agriculture.

Urban green spaces provide essential ecosystem services, yet national-scale economic assessments remain scarce in rapidly urbanizing countries. Here, we quantify the ecosystem service value (ESV) of China’s urban green spaces from 1996 to 2024 using national statistical data and eight key indicators: water conservation, carbon sequestration, oxygen release, dust retention, biodiversity protection, nitrogen oxide absorption, cooling effects, and leisure recreation. Valuation follows Costanza et al. and the Millennium Ecosystem Assessment. We apply the full permutation polygon graphic method (FPPGM) to derive a comprehensive service index and the Eco-Economic Harmony (EEH) index to assess ecological–economic coordination. Total ESV increased from 57.18 billion to 569.01 billion yuan, at an average annual rate of 8.55%. Cooling effects, biodiversity protection, and water conservation ranked as the top three services. The comprehensive service index improved continuously, with national sustainable development capacity progressing from Level 4 (Low) in 1996–2002 to Level 1 (High) in 2013–2024. The 2024 EEH index of 0.87 indicates moderate-to-high eco-economic coordination. Despite substantial ESV growth, urban economic expansion continues to outpace ecological gains. Strengthening legal protections for urban green spaces is critical. This study provides a transferable framework for assessing urban green infrastructure across developing countries. Full article

Poly(vinylpyrrolidone) hydrogels net(PVP) were synthesized by gamma radiation at a dose rate of 11.8 kGy h⁻¹ and subsequently functionalized with maleic acid (MA) via radiation-induced grafting using the direct method to obtain pH-responsive hydrogels for the loading and controlled release of bioactive compounds. Under the selected conditions, MA grafting reached approximately 18%. The obtained hydrogels were characterized by Fourier transform infrared spectroscopy (FTIR-ATR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and swelling studies. The results confirmed the successful incorporation of MA into the hydrogel network and demonstrated that grafting imparted pH-responsive behavior due to the ionization of carboxylic acid groups, yielding two critical pH values at 4.4 and 6.0. Loading and release studies using naringin and benzalkonium chloride showed that the grafted hydrogels exhibited enhanced loading capacity and sustained release profiles governed by the hydrogel network and by interactions between the loaded compounds and the carboxylic groups from MA. Furthermore, hydrogels loaded with antimicrobial agents effectively inhibited the growth of Escherichia coli and Staphylococcus aureus. These findings demonstrate that gamma radiation-induced MA grafting is an effective strategy for developing pH-responsive PVP hydrogels with potential applications as multifunctional wound dressing materials.

Soil yeasts represent a significant component of the agricultural microbiota and possess high ecological and biotechnological potential in production systems such as those for sugarcane. This review analyses the importance of these microorganisms in fundamental processes related to soil health and functionality, highlighting their role in nutrient cycling, the decomposition of organic matter, and the availability of essential elements for plant uptake. Numerous studies have shown that certain yeasts possess plant-growth-promoting characteristics, including the production of phytohormones, siderophores and compounds capable of solubilizing nutrients, thereby promoting plant development and the sustainability of the agroecosystem. Furthermore, this review highlights the potential of yeasts as agents for the biological control of agricultural diseases and pests. Various mechanisms of action are described, including the production of volatile organic compounds, hydrolytic enzymes, antagonistic toxins, competition for nutrients and space, and the induction of defense responses in plants. In sugarcane systems, some yeast species such as Metschnikowia spp., Meyerozyma guilliermondii, Wickerhamomyces anomalus, Pichia spp., and Rhodotorula glutinis have demonstrated antagonistic activity against plant pathogens and the potential to be integrated into sustainable agricultural management strategies.

Mental health counselors routinely work in emotionally demanding environments that require sustained psychological and occupational functioning. Identifying psychological resources and occupational factors that support adaptive functioning may inform strategies to enhance counselor well-being and reduce burnout. This study examined the relationships among counselors’ clinical service context, emotion regulation, growth mindset, self-compassion, job satisfaction, and burnout. Participants were 152 individuals with graduate degrees who provided counseling services and completed an anonymous online survey. Measures assessed burnout, job satisfaction, self-compassion, growth mindset, cognitive reappraisal, expressive suppression, and workplace and professional characteristics. Group comparisons and hierarchical regression analyses were conducted. Burnout was significantly associated with lower job satisfaction, self-compassion, cognitive reappraisal, and growth mindset. Counselors providing services to children reported greater burnout and lower self-compassion, whereas those providing services to adults reported greater cognitive reappraisal, higher job satisfaction, and lower burnout. Job satisfaction varied across service settings, with the highest levels observed in outpatient community mental health and private practice and the lowest in detention centers and K–12 schools. In hierarchical regression analyses, only job satisfaction and self-compassion independently predicted burnout after controlling for counseling experience, degree characteristics, growth mindset, and emotion regulation. Counselors’ adaptive functioning appears to reflect the combined influence of workplace context and psychological resources. Self-compassion and job satisfaction emerged as key protective factors against burnout. These findings have implications for counselor education, clinical supervision, workforce development, and interventions designed to promote occupational well-being and strengthen the behavioral health workforce.

China pushes forward two key national strategies, namely common prosperity and Healthy China. Many papers have discussed how urban common prosperity and urban healthy development evolve across space, yet most of these works cannot match the practical needs of local high-quality urban construction in Guangdong. This study takes various cities in Guangdong Province as the research area and utilizes multi-source big data from 2010 to 2025 so that it constructs a multidimensional evaluation system for the two major systems. Subsequently, this research employs methods including a deep weighted neural network to conduct empirical analysis. The results show that the urban common prosperity index in Guangdong Province exhibits an overall continuous upward trend. However, common prosperity gradually deviates from the development pattern that matches the economic driving forces. Meanwhile, the prominent advantages of urban healthy development gradually shift from eastern Guangdong to the core area of the Pearl River Delta, which establishes an overwhelming leading position for the Pearl River Delta. Furthermore, the regional development level plays a certain promoting role in healthy development. Spatially, common prosperity and urban healthy development exhibit phased non-linear characteristics, which encompass synchronous growth, growth rate divergence, and trend deviation. This study provides empirical evidence and practical support for Guangdong Province so that policymakers can comprehensively advance common prosperity and healthy city construction. Ultimately, these efforts optimize the regional development layout, which promotes high-quality and sustainable urban development. Full article

Currently, controlled-environment agriculture (CEA) and hydroponic production systems represent sustainable alternatives for improving leafy vegetable production by controlling the variables that influence their growth. This research studied the effect of variations in photoperiod and nutrient solution concentration on the development of a hydroponic crop. The response variables analyzed were growth, physiological response, and nutrient content of chard. The hydroponic cultivation technique used was the Nutrient Film Technique (NFT) under controlled environmental conditions. The experimental design was developed with two photo-period treatments: 12 h light/12 h darkness and 10 h light/14 h darkness, combined with three levels of nutrient concentration at 100%, 75% and 50% of the standard Steiner formulation. The data were analyzed using two complementary approaches: (1) ANOVA with Tukey’s post-hoc test to identify specific group differences, and (2) principal component analysis (PCA). It was observed that the concentration of the nutrient solution had a significant effect on the growth and nutritional quality variables of the crop. Treatments with a 100% nutrient solution resulted in higher values for plant height, biomass, protein, potassium, and calcium. Reducing the nutrient solution concentration resulted in a clear decrease in crop growth variables. The effect of photoperiod on crop development was found to be less significant. The PCA accounted for 96.8% of the total variability. This indicates that nutrient concentration was the primary factor associated with growth and nutritional content in chard. The results show that nutrient reduction directly affects crop productivity and nutritional quality. However, moderate variations in photoperiod had a secondary effect under the conditions evaluated. This research provides relevant information for developing nutritional management strategies and sustainable production in controlled-environment hydroponic systems. It also contributes new knowledge on integrating hydroponic crops in controlled environments into sustainable agri-food systems using Internet of Things (IoT) technologies for efficient crop management.

Rapid and unplanned urbanization in Dhaka is reshaping land use, intensifying peripheral expansion, and increasing pressure on urban and ecological resources. Understanding these growth dynamics is essential for effective urban growth boundary delineation and sustainable planning, yet integrated assessments of historical and future urban growth remain limited. The current study evaluates spatiotemporal urban expansion from 2010 to 2025, delineates the urban growth boundary using a morphological framework, and simulates future growth for 2030 through a coupled cellular automaton-neural network model. Multi-temporal Landsat imagery (2010, 2015, 2020, and 2025) was classified in Google Earth Engine using supervised Maximum Likelihood Classification. Urban growth patterns were quantified using the urban expansion intensity index (UEII), annual urban expansion rate (AUER), and landscape expansion index (LEI). The urban largest continuous patch index (ULCPI) approach was applied to extract functional urban boundaries. Model performance was validated using the Chi-square (χ²) goodness-of-fit test. Results show a substantial increase in built-up land from 115.85 km² to 171.42 km² between 2010 and 2025, accompanied by a decline of approximately 60 km² in urban green spaces. LEI results demonstrate a transition from compact infilling growth (2010–2015) to dominant edge and outlying expansion (2015–2020), indicating progressive peri-urbanization. The urban largest continuous patch (ULCP) nearly doubled from 78.58 km² to 152.13 km² over the same period, accentuating rapid spatial consolidation. The 2030 projection anticipates continued corridor-oriented expansion, particularly toward the northern and eastern peripheries, with predictive agreement from the CA–ANN model (χ² = 0.03 < 7.8). The study identifies a clear transition from monocentric compactness to polycentric expansion, emphasizing the necessity for enforceable growth containment, transit-oriented development, and ecologically responsive planning strategies to ensure long-term urban sustainability.

Green finance has emerged as a critical mechanism for aligning capital markets with climate and sustainability objectives, particularly as economies face mounting pressure to transition away from carbon-intensive growth models. In hydrocarbon-dependent regions such as the Gulf Cooperation Council (GCC), this transition poses distinctive challenges that require integrated institutional, policy, and financial frameworks. The global transition toward sustainable finance has gathered significant momentum, with green capital markets emerging as a central mechanism for channeling investment toward climate and development objectives. Hydrocarbon-dependent economies face a distinctive challenge in this transition, as they must reconcile resource-based growth models with rising pressures for environmental accountability and low-carbon diversification. This study develops an integrated theoretical framework to examine how Gulf Cooperation Council (GCC) financial systems are transitioning toward green capital markets, drawing on institutional theory, environmental policy pathway analysis, and climate-finance alignment models. Using descriptive statistics from regional stock exchanges covering 2015–2024, the study maps key trends in sustainable asset growth, institutional investor preferences, and regulatory evolution across the GCC. Findings indicate progressive alignment with global ESG norms; sustainable asset valuations grew at 23.5% CAGR (UAE) and 18.7% CAGR (Saudi Arabia). A fixed-effects panel regression with panel-corrected standard errors is estimated across all six GCC economies; regulatory framework maturity emerges as the strongest predictor of green bond issuance (β = 0.47, p < 0.01). Cumulative green bond issuances reached USD 52.6 billion (2015–2024), with renewable energy accounting for 58.1% of the sectoral allocation and green transportation recording a 55.9% CAGR (2020–2024). Policy recommendations focus on GCC-wide harmonization of mandatory ESG disclosure, adoption of a unified green bond taxonomy, and expansion of concessional green financing mechanisms. Substantial cross-country heterogeneity is documented, driven by differences in energy policy commitment, financial market maturity, and institutional capacity. The proposed framework offers specific policy guidance to accelerate green financial integration in the GCC, emphasizing regulatory harmonization, institutional capacity-building, and alignment with SDG targets 7 and 13. The study contributes to the limited evidence base on green finance in hydrocarbon-dependent economies and provides a foundation for future empirical research. Given the small panel dimensions (N = 6 cross-sectional units; T = 10 years), this study is positioned as exploratory rather than confirmatory: the panel-regression estimates and the hypothesized institutional-to-policy-to-finance sequence are interpreted as associational patterns consistent with the proposed framework rather than as definitive causal tests, and the reported coefficients are offered as indicative magnitudes to be re-examined as longer GCC green-finance time series become available.

Sustainable settlement governance requires construction land to remain coordinated with population change, as persistent land–population mismatches undermine both resource sustainability and settlement quality, yet much of the land-use efficiency research still treats urban and rural space as a binary system. This study develops a city–town–village framework to examine the divergent evolution of construction land per capita and internal land allocation in 336 prefecture-level units in China from 2010 to 2020. Using national land survey data, population census data, location quotients, exploratory spatial analysis, hierarchical clustering, and regression models, the results indicate pronounced asymmetric decoupling of construction land from population across the settlement hierarchy. City-level land expansion was broadly synchronized with population growth, leaving per capita construction land almost unchanged; towns experienced expansion-driven decoupling as land expansion outpaced population growth; and villages showed severe decoupling: village construction land expanded by 17.6% while the population declined by 23.1%, raising village per capita construction land by 52.9%. At the national level, construction land increased by 24.2% while population grew by only 5.8%. Within prefectures, relative land allocation shifted away from cities and toward villages, with city location quotients declining and village location quotients rising in most prefectures. Regression analysis indicates that physical terrain, development stage, sectoral structure, fiscal expenditure capacity, administrative hierarchy, and regional location are jointly associated with these divergent outcomes. The findings indicate that towns are not simply small cities and that village land stranded by depopulation rather than active sprawl has become a major component of the national land–population imbalance. Policy should therefore extend land-use efficiency governance from metropolitan growth control to differentiated regulation of towns and villages. Full article

As religious tourism expands across Asia, it remains unclear who benefits from its growth and who is overlooked in policy and industry accounts. Drawing on fieldwork in the temple-towns of Jejuri and Tuljapur in Maharashtra, India, this paper aims to make a timely and original contribution about the significance of informal, family-run and ritual-linked enterprises to the centre of debates on entrepreneurship and inclusive tourism development. The study combines visitor surveys, detailed enterprise mapping and entrepreneur interviews to reveal a dense but precarious local economy which is sustained by religious retail (a term articulated for sale of items related to rituals), street vending and small-scale service provision. These micro-enterprises are culturally central but economically fragile, low-margin and weakly recognised in policy. The paper argues that entrepreneurship is constrained by traditional religious authority, informality, seasonality and limited innovation capacity, while rising visitor numbers are creating opportunities in travel, accommodation and food. It shows that sustainability in temple-towns depends on livelihood durability, socio-cultural continuity, participatory governance and distributional justice. By foregrounding actors often omitted from formal economic analysis, the paper reframes religious tourism as an embedded entrepreneurial ecosystem and calls for policies that strengthen local enterprise capability, resilience and participation.

Recent advances in numerical modelling, remote sensing, and artificial intelligence are bringing a transformation in our ability to assess sediment transport. Nevertheless, climate change is fundamentally altering sediment production, transport, and deposition through intensifying hydrological extremes, sea-level rise, changing storm regimes, cryosphere degradation, and increasing human modification of sediment pathways. These interacting drivers challenge conventional sediment transport assessment, which has largely evolved within separate fluvial, estuarine, coastal, and marine disciplines and often lacks an integrated perspective capable of representing source-to-sink sediment connectivity under non-stationary environmental conditions. Although significant advances have been made in process-based numerical modelling, Earth observation, and artificial intelligence (AI), these approaches are commonly reviewed independently, limiting their collective application to regional climate-responsive sediment assessment. This review examines state-of-the-art process-based numerical models, observational tools, and machine-learning approaches for sediment transport from source-to-sink. A transparent benchmarking scheme is used to compare leading modelling systems (e.g., AdH, SRH-2D, FLO-2D, HEC-RAS, TELEMAC, Delft3D, EFDC, SCHISM, XBeach, ROMS), highlighting differences in dimensionality, sediment-process representation, computational demands, and climate-scenario readiness. Remote sensing (optical, SAR, LiDAR, UAV) and AI/ML/DL methods (e.g., random forests) are reviewed as complementary tools that enhance model parametrization, improve validation, and address uncertainty in data-limited regions. A reproducible bibliometric synthesis based on Dimensions.ai records (2000–2026) reveals accelerating growth in sediment-transport research, with strong recent expansion in coastal, estuarine, and data-driven modelling applications. Major challenges include cohesive sediment physics, cross-environment coupling, limited long-term validation datasets, and the need for scalable workflows compatible with climate-model forcing. In this manuscript, we analyse and propose a future roadmap for near-term integration of satellite–field data streams, medium-term development of hybrid physics–AI models, and long-term coupling of sediment modules within Earth-system and regional climate frameworks. Collectively, this review provides a foundation for next-generation, climate-responsive sediment transport assessment supporting sustainable river basin and coastal management. Full article

Mushroom mycelium-based biomaterials are eco-friendly, biodegradable, cheap, and sustainable materials. In this study, ten wild mushroom species were collected from tropical forests in Chiang Mai and Chiang Rai provinces, and two commercial mushroom species were obtained from a local market in Chiang Rai Province, Thailand. Mushroom specimens were identified based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer (ITS) region. All fungal species were determined to use suitable agar media (potato dextrose agar; malt extract agar), liquid media (malt extract broth), and agricultural substrate (rubber sawdust size ≤ 2 mm) for mushroom mycelial growth. Mechanical property evaluation using Ashby’s chart indicated that the resulting mushroom mycelium-based biomaterials have the potential to substitute for certain types of synthetic foam. A biodegradability test was conducted through soil burial of samples for 90 days, which demonstrated cumulative weight loss exceeding 60%, thereby confirming biodegradability. Furthermore, a new approach for maintaining mycelial viability was developed and validated, addressing the challenge of maintaining vigorous mycelium. Notably, this study presents the first comprehensive report on the application of Coriolopsis brunneoleuca, Ganoderma tropicum, Hexagonia sp., Microporus xanthopus, Trametes polyzona, and T. sanguinea in mushroom mycelium-based biomaterial production, including material development, characterisation, and prototype fabrication. Based on the material properties and successfully developed prototypes, the mushroom mycelium-based biomaterials produced in this study are potentially suitable for applications in packaging, indoor products, construction, and insulation purposes, as a viable alternative to conventional synthetic materials.
