This study examines the impact of digitalisation, innovation activity, demographic factors, and macroeconomic variables on employment in European Union countries within the framework of sustainable development. The empirical analysis is based on Eurostat panel data for 2015–2023 and applies regression analysis to identify the key determinants of employment. The results indicate that digitalisation demonstrates the strongest positive statistical association with employment, confirming its important role in labour market transformation and inclusive economic development. Expenditures on research and development also show a positive effect, highlighting the significance of innovation activity for employment growth. At the same time, GDP per capita does not exhibit a statistically significant relationship with employment, while education expenditure demonstrates a negative short-term effect. The findings suggest that digitalisation and innovation contribute not only to employment growth but also to the expansion of labour market participation opportunities for diverse social groups. The study contributes to the analysis of SDG 8 (Decent Work and Economic Growth), SDG 9 (Industry, Innovation and Infrastructure), and SDG 10 (Reduced Inequalities) by identifying the structural factors associated with employment dynamics in the digital economy.

Plant-parasitic nematodes (PPNs) rank among the most economically destructive soilborne pathogens worldwide, causing annual crop losses estimated at USD 125–175 billion. Traditional management of plant parasitic nematodes has depended significantly on synthetic nematicides; however, increasing regulatory constraints, environmental pollution, and the rise of resistant nematode populations have generated an urgent need for sustainable alternatives. Humic substances (HS), comprising humic acids, fulvic acids, and humins derived primarily from leonardite and lignite, represent biologically active components of soil organic matter. Their different functional groups, like carboxylic, phenolic, and carbonyl groups, have direct nematicidal and nematostatic effects by stopping eggs from hatching, slowing down juvenile development, and lowering infectivity. They also indirectly improve soil structure, nutrient bioavailability, and the composition of the rhizosphere microbiome. Plant growth-promoting rhizobacteria (PGPR), particularly Bacillus spp. and Pseudomonas spp., suppress PPN populations through antibiotic biosynthesis, cuticle-degrading hydrolytic enzymes, nematostatic volatile organic compounds, and elicitation of induced systemic resistance (ISR). This review methodically analyzes the individual and synergistic processes by which HS and PGPR inhibit PPNs and enhance plant growth. Humic compounds strongly promote PGPR rhizosphere colonization, augmenting microbial metabolic activity and bioinoculant stability, hence producing combinatorial suppressive effects unattainable by either input independently. The combined HS-PGPR approach is reliable and environmentally sustainable for comprehensive nematode control, requiring multidisciplinary research to achieve global sustainable agriculture.

Background/Objectives: Phyllostachys edulis is the most widely distributed and economically important bamboo species in China. However, the genetic transformation in P. edulis is still limited by a long regeneration cycle and low regeneration and transformation efficiency. Carbon nanotube-based delivery systems in plants have the advantages of simplicity, rapidity and low cost. Moreover, morphogenetic regulators BBM (BABY BOOM) and WUS (WUSCHEL) play significant roles in plant regeneration. Methods: Here, immature zygotic embryos were used to induce P. edulis callus, and using single-walled carbon nanotubes (SWNTs)-based delivery technology, PeBBM2, PeWUS-DNA (with introns) and PeWUS-cDNA (without introns) were introduced to P. edulis callus either individually or in combination. Conclusions: The results showed that the 0.9–1.0 mm (long axis) embryos exhibited the lowest contamination rate and the highest induction efficiency. Moreover, the results indicated that the co-transformation of PeBBM2-PeWUS more effectively boosted the growth area of the callus. However, only the PeBBM2-overexpression callus could form shoots. Compared with the wild type, the PeBBM2-overexpression lines showed reduced expression of AGL15 and increased expression of IAA30 and YUC. In conclusion, these findings suggested that SWNTs-mediated DNA delivery is a potential strategy for the genetic transformation of P. edulis callus. Additionally, the findings indicate‌ that the PeBBM2 and PeWUS genes can accelerate callus enlargement in P. edulis, whereas PeBBM2 might play a more important role in shoot formation. This study provides a basis for developing a genetic transformation system for plants based on SWNTs-mediated DNA delivery and morphogenetic regulators. Full article

Urban development in medium-sized provinces is increasingly influenced by the interplay of demographic change, socio-economic disparity, and labour market structure. However, these dimensions are frequently examined in isolation, which limits their utility for integrated regional planning. This study offers a planning-oriented assessment of Amasya Province, Türkiye, by integrating population projections, district-level socio-economic disparity analysis, and labour market indicators to evaluate the province’s developmental trajectory toward 2035. The study utilizes official population data for 2007–2024, district-level socio-economic status scores for 2023, and provincial labour market indicators. Linear trend projection and compound annual growth rate analysis were employed to estimate population change, while the Gini coefficient, Theil index, and coefficient of variation were used to assess intra-provincial socio-economic disparities. Labour market performance was evaluated through participation, employment, unemployment, and employment-to-participation efficiency indicators. The results indicate that Amasya is projected to experience a moderate population increase, reaching approximately 350,118 inhabitants by 2035. Growth is anticipated to remain concentrated primarily in the Central District and Merzifon, while socio-economic advantages also exhibit a central–peripheral pattern. Labour market indicators suggest relatively stable employment performance, although more detailed sectoral, gender, and age-specific analyses are necessary for more robust conclusions. The study contributes an integrated framework for linking demographic projection, socio-economic hierarchy, and labour market capacity in medium-sized provincial planning. The findings suggest that future planning should focus on managing growth in central districts while supporting balanced development in peripheral districts. Full article

Phytopathogenic bacteria and fungi significantly reduce fruit and vegetable yields, resulting in substantial economic losses. Conventional management relies on synthetic agrochemicals; however, their intensive use poses risks to human health, environmental integrity, and biodiversity. Snake venoms have evolved under selective pressure, developing specialized components with potent antimicrobial properties as part of a defense mechanism against prey-borne microorganisms. This study evaluated the inhibitory potential of Micrurus venoms against pathogens of agricultural interest and developed bioactive gelatin-based films incorporated with purified L-amino acid oxidases (LAAOs) as a novel biocontrol strategy. Venoms from M. ancoralis, M. mipartitus, and M. dumerilii exhibited significant growth inhibition against Xanthomonas and Fusarium strains. The primary active component was identified as LAAO through biological activity and mass spectrometry. Biofilms were formulated by incorporating M. ancoralis venom and its purified LAAO into a gelatin matrix. Physicochemical and microbiological characterization, alongside in situ assays on strawberries, demonstrated that the functionalized biofilms retained potent antimicrobial activity. Furthermore, LAAO incorporation did not significantly alter the physicochemical properties of the fruit but effectively extended shelf life by reducing weight loss and maintaining sensory appearance. These findings highlight the biotechnological potential of elapid venom components in the development of alternatives for phytopathogen control and active food packaging. Full article

This paper investigates the evolution and driving mechanisms of the Coupling Coordination Degree (CCD) between urban development (UD) and ecological efficiency (EE) in the Yangtze River Delta (YRD) urban agglomeration. Using panel data for 27 cities from 2013 to 2023, a comprehensive evaluation model and the CCD model are used to measure the level of coordination across cities. A fixed-effects panel regression model is constructed to systematically examine the effects of economic development and education expenditure on CCD, focusing on the moderating role of education expenditure. The empirical results indicate that: (1) CCD in the YRD shows a clear upward trend, gradually shifting from disorder to coordinated development; (2) inter-city disparities remain evident, reflecting differences in development foundations, industrial structures, and governance capacities; (3) economic development significantly promotes CCD by providing material and institutional support for urban–ecological coordination; and (4) education expenditure strengthens this positive relationship by enhancing human capital accumulation and knowledge spillovers. The findings highlight the importance of integrating economic growth with human capital investment to promote green and high-quality urban development. Full article

Assessing environmental flows downstream of reservoirs under changing climate and increasing water demand remains a critical challenge in catchment management. This study presents an integrated framework for optimizing environmental flow releases by explicitly linking reservoir operation with climate change and population growth. The key novelty lies in the development of a modified objective function that incorporates environmental flow requirements alongside evolving hydrological and demand conditions. Reservoir inflows were simulated using an artificial intelligence-based rainfall–runoff model, employing a neuro-fuzzy inference system to capture nonlinear relationships between climate variables and runoff. Future rainfall projections were derived from four general circulation models (ACCESS1.0, CanESM2, MIROC5, and NorESM-M1) across four-time horizons (2021–2040, 2041–2060, 2061–2080, and 2081–2100). The simulated inflows were coupled with a reservoir operation model to optimize environmental flow releases, with system performance evaluated using reliability and vulnerability metrics. Results show that climate change alone has a limited impact on environmental flow supply; however, when combined with population-driven increases in water demand, significant reductions in system performance occur. In the worst-case scenario, the reliability of meeting environmental flow requirements drops below 20%, accompanied by a marked increase in system vulnerability. These findings demonstrate that water demand pressures play a dominant role in shaping future environmental flow availability. The proposed framework provides a robust and adaptable approach for integrating hydrological variability and socio-economic drivers into reservoir management, supporting more informed decision-making for balancing water supply and ecosystem sustainability under future uncertainty.

This study analyzes a balanced panel of 41 Yangtze River Delta cities from 2006 to 2021 to assess whether and why economic growth has decoupled from industrial pollution. Furthermore, this study proposes a two-dimensional decoupling framework that combines Tapio elasticity with development stages, quantifies driver contributions using an LMDI–Tapio decomposition, and estimates spatial β-convergence in pollution intensity. Key findings include the following: (1) By 2021, all YRD cities exhibit decoupling, with heterogeneity across pollutants and cities. (2) Technological progress effect is the dominant enabler of decoupling, while economic development poses a significant barrier. (3) Industrial sulfur dioxide, smoke and dust intensity, and the composite industrial pollution index show notable spatial β-convergence, with smoke and dust intensity converging most rapidly. The results inform technology-focused policies and cross-city coordination in the YRD. Full article

Access to freshwater is one of the major global challenges, driven by population growth, industrial development, climate change, and increasing water stress, particularly in economically constrained regions. In this context, this study designs, builds, and experimentally and numerically evaluates an indirect solar concentration desalination system (ICST) composed of a humidification–dehumidification (HDH) subsystem thermally powered by a Linear Fresnel Concentrator (LFC) under the appropriate technology paradigm. The methodology integrates an experimental campaign conducted under real climatic conditions in Bucaramanga, Colombia, mathematical modeling based on mass and energy balances, and the implementation of a TRNSYS simulation model validated through qualitative and quantitative analyses using absolute and relative errors. Results showed close agreement between experimental and simulated data, with daily freshwater production deviations of 0.53 and 0.65 L/day in tests 04 and 05, respectively, while mean relative errors remained below 5% for the main thermal and productivity variables. Experimentally, an average freshwater production of 1.13 L/h was achieved, with a production gain ratio (GOR) of 0.32 and a recovery ratio (RR) of 0.021, while maintaining total dissolved solids below 500 mg/L. Economic assessment estimated a production cost of $0.065/L, demonstrating the technical and economic feasibility of the system for decentralized small-scale applications in regions with high solar irradiance throughout the year.

Triplophysa siluroides, a unique species of plateau fish, holds significant economic value. However, its natural population has sharply declined due to overfishing and the construction of water conservancy projects. Investigating the various conditions necessary for its growth is a crucial prerequisite for successful artificial breeding. This study used Edwardsiella tarda as the pathogenic bacterium to determine the median lethal concentration following infection of T. siluroides, as well as to examine changes in tissues, organs, and gene expression. The study found that dead T. siluroides displayed symptoms such as abdominal distension, fluid accumulation, and a reddened anus, and the median lethal concentration of E. tarda for T. siluroides was calculated to be 1.00 × 10⁶ CFU/mL. Following infection with E. tarda, the liver, intestine, gills, spleen, and kidneys exhibited varying degrees of lesions. Transcriptome sequencing identified a total of 54,667 genes. Compared to the blank control group, 192 genes were downregulated and 125 genes were upregulated in T. siluroides infected with E. tarda. In contrast, after infection with the poly(I:C) viral mimic, 225 genes were downregulated and 436 genes were upregulated. This study determined the median lethal concentration of E. tarda for T. siluroides via intraperitoneal injection under laboratory conditions. The results may contribute to disease prevention and control in the breeding of T. siluroides, as well as inform future risk assessments of infection in aquaculture water bodies. Full article

The rapid growth of electric vehicle (EV) adoption requires the scalable and cost-effective deployment of publicly accessible charging infrastructure, where cost-effectiveness is understood in terms of infrastructure reuse rather than explicit economic optimisation. Integrating slow AC charging units into existing public lighting networks represents a promising infrastructure reuse strategy, though spatial feasibility, electrical constraints, and regulatory requirements must be addressed. This study proposes an integrated GIS–MCDA–MILP framework for the optimal allocation of EV charging stations within public lighting systems. GIS-based spatial analysis identifies feasible poles based on parking accessibility and demand indicators, while MCDA ranks candidate locations and a MILP model determines optimal deployment under capacity constraints and phased rollout scenarios. The framework also incorporates AFIR-based policy benchmarking to assess compliance under current and future EV adoption levels. A real-world case study identifies 1223 feasible poles with a structural hosting capacity of 368 chargers. The results demonstrate that such integration is viable at the spatial and cabinet-capacity planning level but structurally limited, with a critical fleet growth multiplier of approximately 3.4 identified as the threshold beyond which lighting-integrated deployment alone becomes insufficient for AFIR compliance. The proposed framework advances the state of practice by coupling spatial, electrical, and regulatory analysis within a single reproducible methodology, offering a transferable decision-support tool for sustainable urban EV charging planning.

The Gulf Cooperation Council (GCC) countries consistently rank among the highest per capita CO₂ emitters globally, yet rigorous empirical analysis of the structural drivers of these emissions in the post-Paris Agreement era remains scarce. This study investigates the determinants of CO₂ emissions per capita across six GCC economies—Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates—over the period 2015–2022, using pooled ordinary least squares (OLSs) and country fixed effects (FEs) panel regression models with country-clustered standard errors. The focal explanatory variable is energy use per capita, complemented by GDP per capita, trade openness, urbanization, foreign direct investment (FDI), and industry value added as controls. A quadratic income term explicitly tests the environmental Kuznets curve (EKC) hypothesis. Results consistently show that energy use is the dominant driver of emissions. The EKC hypothesis is supported in the FE framework. The implied turning point of approximately USD 85,500 per capita (constant 2015 USD) is already exceeded by Qatar (panel mean: USD 114,835) and approached by the UAE (USD 71,434), while Bahrain (USD 55,681), Kuwait (USD 51,531), Saudi Arabia (USD 61,232), and Oman (USD 38,591) remain on the EKC’s rising slope, consistent with their continued emissions’ growth trajectories. Urbanization exerts a significant positive within-country effect on emissions. Trade openness reduces emissions in cross-sectional specifications, while FDI is systematically insignificant. These findings support energy efficiency reforms, renewable energy expansion, and low-carbon urban planning as the most effective policy levers for GCC decarbonization. Full article

This study evaluates how environmental regulation influences enterprise management practices in the YREB of China, which faces a dilemma between economic growth and ecological conservation. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines, a qualitative systematic review of empirical studies published between 2015 and 2025 was conducted. The data were retrieved via Web of Science and Scopus, supplemented by Google Scholar and ScienceDirect. Subsequently, thematic analysis and data visualization were conducted by MAXQDA 2024. The findings synthesize evidence across key themes, environmental information disclosure (EID), green innovation, governance adaptation, and regional disparity themes to synthesize key empirical findings. From the perspectives of Institutional Theory and Stakeholder Theory, the findings suggest that environmental regulation is not only a compliance burden, but also a force for enterprise change, driving EID practices and innovation-oriented competitive advantages. The results further suggest that when institutions are more developed or policy implementation is more stable, enterprises are better able to adjust, implying that downstream regions are more flexible than upstream regions. Other instruments to close the implementation gap and support sustainable development are multi-level governance, context-specific policy instruments, and Integrated Water Resource Management. Also, it may be highlighted that effectiveness in environmental governance relies on governance quality, institutional capacities, and regionally differentiated aspects. Future research should better identify causal mechanisms and improve cross-region learning to improve equitable and effective environmental governance in China’s evolving socio-ecological context.
