The effects of integrated nutrient-management (INM) practices on soil quality are essential for sustaining agro-ecosystem productivity. The soil quality index (SQI) serves as a tool to assess the physical, chemical, and biological potential of soils as influenced by various edaphic and agronomic practices. A multiyear (2018–2021) field experiment was performed at the University Organic Research Farm, Narendrapur, West Bengal, India, to investigate the influence of integrated and sole applications of different conventional fertilizers, organic (e.g., vermicompost), and natural farming inputs (e.g., Dhrava Jeevamrit and Ghana Jeevamrit) on SQIs and crop productivity of rice–mustard–green gram-based cropping systems. A total of 12 parameters were selected for the assessment of SQI, amongst which only four, namely pH, organic carbon %, total actinomycetes, and bulk density, were retained for the minimum data set based on principal component analysis (PCA). In this study, the maximum SQI value (0.901) of the experimental soil was recorded in the INM practice of 25% organic and 25% inorganic nutrient inputs, and the rest with natural farming inputs, which augments the SQI by 24% compared to the 100% inorganic nutrient treatment. Amongst the different soil parameters, the highest contribution was from the pH (35.18%), followed by organic carbon % (26.77%), total actinomycetes (10.95%), and bulk density (6.98%). The yields in different cropping systems varied year-wise across treatments. Notably, the highest yield in rainy rice was estimated in the 100% organic treatment, followed by INM practices in the subsequent years, and finally, the combination of organic and natural inputs in the final year. In the case of mustard, the combination of organic and natural inputs resulted in the highest productivity in the initial and last years of study, while the 100% organic treatment resulted in higher productivity in subsequent years. Green gram showed a dynamic shift in yield between the 100% organic and integrated treatments over the years. Further, a strong correlation was also established between the soil physico-chemical parameters and the SQI. Overall, this study concludes that the natural and organic input-based INM practice enhances the soil quality and crop productivity of the rice–mustard–green gram cropping system under the coastal saline zone.

User location has emerged as a pivotal factor in human-centered environments, driving applications like tracking, navigation, healthcare, and emergency response that align with Sustainable Development Goals (SDGs). However, accurate indoor localization remains challenging due to the limitations of GPS in indoor settings, where signal interference and reflections disrupt satellite connections. While Received Signal Strength Indicator (RSSI) methods are commonly employed, they are affected by environmental noise, multipath fading, and signal interference. Round-Trip Time (RTT)-based localization techniques provide a more resilient alternative but are not universally supported across access points due to infrastructure limitations. To address these challenges, we introduce DistilLoc: a cross-knowledge distillation framework that transfers knowledge from an RTT-based teacher model to an RSSI-based student model. By applying a teacher–student architecture, where the RTT model (teacher) trains the RSSI model (student), DistilLoc enhances RSSI-based localization with the accuracy and robustness of RTT without requiring RTT data during deployment. At the core of DistilLoc, the FNet architecture is employed for its computational efficiency and capacity to capture complex relationships among RSSI signals from multiple access points. This enables the student model to learn a robust mapping from RSSI measurements to precise location estimates, reducing computational demands while improving scalability. Evaluation in two cluttered indoor environments of varying sizes using Android devices and Google WiFi access points, DistilLoc achieved sub-meter localization accuracy, with median errors of 0.42 m and 0.32 m, respectively, demonstrating improvements of 267% over conventional RSSI methods and 496% over multilateration-based approaches. These results validate DistilLoc as a scalable, accurate solution for indoor localization, enabling intelligent, resource-efficient urban environments that contribute to SDG 9 (Industry, Innovation, and Infrastructure) and SDG 11 (Sustainable Cities and Communities).

Annually, the global plastic waste generation adds up to over 353 million tonnes, which is associated with substantial environmental and societal issues, such as microplastic pollution and landfill management. Despite many attempts to integrate sustainable circular economy strategies into the plastic industry, several challenges have resulted in material loss and poor-quality recycled products. To address these challenges, this study proposes a material traceability system to overcome the issue of flawed recycling of plastic. The authors employed a systematic literature review and meta-analysis to summarise the current state of traceability in the plastic recycling industry. The results revealed that blockchain technology is the most promising framework amongst various traceability systems; however, its implementation is hindered for three reasons. First, future systems must prioritise interoperability to ensure seamless integration; second, standardisation is imperative for effective traceability; and third, implementing digital and physical traceability is essential to maximise the value of materials by enabling improved material identification and enhancing sorting efficiency. Further, it emerged that integrating quality control into traceability solutions is essential for improved recycled content in plastic products. By shedding light on these insights, this study contributes to developing traceability systems in the plastic recycling industry, guiding policymakers, industry practitioners, and researchers alike. Ultimately, the implementation of effective traceability mechanisms has the potential to drive plastic circularity by improving material identification, sorting practices, and overall transparency within the industry.

Background/Objectives: The goal of this pilot study is to evaluate adherence to the Mediterranean Food Pattern (MFP) in a self-selected sample of university students, addressing a perspective of food sustainability. In addition, it seeks to relate adherence to MFP with sociodemographic characteristics and nutritional status. Methods: This is a cross-sectional pilot study whose data collection was carried out by an online questionnaire between January and April 2023. Results: Two hundred and forty-eight students participated—most of them were female (78.2%), had a median of 22 (20; 30) years, resided in the central region of Portugal (42.3%), and were pursuing a degree (73.4%) in a public higher education institution (66.5%). The prevalence of overweight (overweight and obesity) found was 33.1%. Females predominantly used olive oil as their main source of fat (95.9%, p = 0.009) and had a higher consumption of sugary drinks (81.4%, p = 0.004) compared to males, who reported usage rates of 85.2% and 63.0%, The median score of the Mediterranean Diet Adherence Screener was 7 points, presented with an interquartile range (Q1: 6, Q3: 8), indicating moderate adherence. The analysis showed no differences between the sexes (p = 0.087). There was also a negative correlation between adherence to the MFP and the body mass index (p = 0.007; r = −0.171). In addition, adherence to the MFP was associated with the area of study and the course attended, with students in health-related fields showing higher adherence. Conclusions: These findings underscore the necessity for targeted interventions aimed at promoting adherence to the MFP among university students, which could contribute to improved health outcomes and enhanced environmental sustainability.

The integration of digital competences into higher education is essential for the promotion of effective and sustainable teaching and learning environments. The aim of this study was to develop and validate the Digital Competence Scale for University Teachers (DCS-UT), an instrument to assess key digital competences of teachers. The development of the scale involved the creation of items based on an extensive literature review, followed by rigorous testing for content and face validity. The psychometric properties of the scale were assessed using data from 411 university teachers, with confirmatory factor analysis (CFA) and structural equation modelling (SEM) to examine the underlying structure of the scale. Reliability was assessed using Cronbach’s alpha, which confirmed the internal consistency of the instrument (0.974). The analysis revealed a robust four-factor structure: digital literacy, digital skills, digital interaction, and technology integration, which together explained 70.284% of the variance. These findings underscore the value of the DCS-UT as a tool to promote sustainable teaching practises by assessing digital competences. By equipping teachers with essential digital competences, the scale supports the long-term adaptability and effectiveness of higher education institutions in an increasingly digital field.

Lesson study, a collaborative teacher professional development approach, has gained popularity internationally and leading the process with teachers plays a key role in making it sustainable in schools. This paper, which draws on a postgraduate university course for prospective school leaders, examines the dynamic roles in leading lesson study. Drawing on the literature on lesson study and leadership, we analyse how postgraduate students lead lesson study while navigating their status as an insider–outsider. Using a theoretical lens informed by the insider–outsider researcher debate, we propose a classification framework to understand lesson study leaders’ statuses. Presenting two case studies, we explore the strategies for the selection of LS participants, communication, and trust-building, as well as the leaders’ dilemmas and learning opportunities. Drawing on the findings, we highlight the central role of reflective practice in leading lesson study and offer insights for practitioners. This study sheds light on the nuanced dynamics of leading lesson study and its implications for the preparation of prospective leaders. Full article

The Yellow River Basin (YRB) is an important grain production base, and exploring the spatiotemporal heterogeneity and driving factors of soil erosion in the YRB is of great significance to the ecological environment and sustainable agricultural development. In this study, we employed the Revised Universal Soil Loss Equation (RUSLE) in conjunction with Transport-Limited Sediment Delivery (TLSD) to explore a modified RUSLE-TLSD for use assessing net water erosion. This modification was performed using sediment data, and the explanatory power of driving factors was assessed utilizing an optimal parameters-based geographical detector (OPGD). The results demonstrated that the modified RUSLE-TLSD can accurately simulate the spatiotemporal distribution of net water erosion (NSE = 0.5766; R² = 0.6708). From 2000 to 2020, the net water erosion modulus in the YRB ranged between 1.62 and 5.33 t/(ha·a). Specifically, the net water erosion modulus decreased in the YRB and the middle reaches of the YRB (MYRB), but it increased in the upper reaches of the YRB (UYRB). The erosion occurred mainly in the Loess Plateau region, while the deposition occurred mainly in the Hetao Plain and Guanzhong Plain. The Normalized Difference Vegetation Index (NDVI) and slope emerged as significant driving factors, and their interaction explained 31.36% of YRB net water erosion. In addition, the redistribution of precipitation by vegetation and the slope weakened the impact of precipitation on the spatial pattern of net water erosion. This study provides a reference, offering insights to aid in the development of soil erosion control strategies within the YRB. Full article

Purpose: the purpose of this study is to investigate whether corporate governance mechanisms and attributes influence the sustainability performance of companies included in the BIST 50 Index. Results and contributions: Regression analysis showed that there was a significant positive influence of board tenure on sustainability performance and all its types; board size on environmental performance; and a dummy variable for board evaluation externally facilitated and company size on sustainability, environmental, and social performance. A significant negative impact of director attendance at board meetings on social performance was also revealed. This study contributes to the literature on the role of corporate governance in achieving the SDGs for BIST 50 Index companies, highlighting the significant impact of its individual indicators on the achievement of sustainability performance. Methodology: The authors reviewed 45 sustainability reports of BIST 50 Index companies for 2023. Four indices—Sustainability Performance, Environmental Performance, Social Performance, and Corporate Governance Performance Indexes—were developed to characterize sustainability performance and its types based on a content analysis of sustainability disclosures. To analyze the influence of mechanisms and characteristics of the corporate governance system on sustainability performance, eight independent variables were used: board size, number of board meetings, director attendance at board meetings, board independence, board tenure, a dummy variable for board evaluation externally facilitated, a dummy variable for internal auditors present, and a dummy variable for CEO and Chair functions combined. Two control variables, company size and leverage, were used as well. Gap: Today, the scientific literature has no universal approach and understanding of how the corporate governance system should be developed to improve sustainability performance or its individual components. Relevance: Development of a corporate governance system is one of the ways to increase the level of sustainability performance of companies. Impact: The results of the study made it possible to produce several recommendations (expand the number of board members, develop an effective procedure for regular changes of general directors in company boards, introduce independent external control tools in the corporate governance systems of companies) that will lead to the achievement of SDGs 5, 8, 16.

Sustainable development is one of the main directions of modern agriculture. First of all, sustainability in the agricultural sector can be achieved through the possible abandonment of traditional mineral fertilizers. Many decades of using these fertilizers have led to the degradation of arable soils and to soil and environmental pollution. As a result, this causes reductions in yields and the environmental quality of agricultural products and affects the health of the population. An alternative to traditional mineral fertilizers may be the use of innovative organomineral fertilizers obtained from local resources. These include manure, humus, compost, sediments, etc. In recent years, fertilizers obtained from the sapropels of the bottom sediments of lakes have become widespread. Their distinctive feature is the environmental friendliness and completeness of the content of chemical elements and substances necessary for the development and growth of plants. In addition, the methods of obtaining and applying these fertilizers allow us to talk about their effectiveness in use. The range of applications of these fertilizers is diverse, from use in the form of a dry extract applied directly to the soil to the use of liquid suspensions used at various stages of processing and from pre-sowing seed treatment to watering and spraying plants at different periods of vegetation. Moreover, an important aspect is the research work on the variational use of sapropel fertilizers on different crops, with different methods of production and concentrations and at different stages of processing. This publication contains the results of a study of the effect of the obtained innovative sapropel fertilizer on productivity, wheat grain quality, and economic efficiency (Triticum aestivum L.). To identify the optimal concentration of sapropel extract, laboratory studies were carried out to determine the germination energy and germination of wheat seeds of different varieties when they were soaked in various concentrations: 0.4, 0.8, 1.2, 1.6, and 2.0 g/L. The best indicators of germination energy and germination of wheat seeds during treatment with the extract were obtained at a concentration of 1.2 g/L. The research was conducted at an accredited variety testing laboratory. A field experiment was conducted in the fields of the agrobiological station of North Kazakhstan University named after Manash Kozybayev. The treatment of the seeds was carried out by soaking them in sapropel extract to evenly distribute the substance. The scheme of the field experiment included the option of using foliar treatment with a solution of sapropel extract at the tillering stage. As a result of the application of the obtained extract in the field, environmental and socio-economic efficiency was noted. The conducted field studies note its positive effect and effectiveness on the morphological, qualitative, and quantitative indicators of the wheat harvest. In the areas where wheat seeds were pretreated, as well as where foliar treatment with the resulting sapropel suspension was carried out, the best yield indicators were revealed. In these variants of the experiment with pre-sowing and pre-sowing and foliar treatment with the sapropel extract solution, the yield was 3.63 and 3.81 tons per hectare, respectively. The introduction of sapropel extract at the stage of seed treatment before sowing, as well as foliar processing of wheat at the tillering stage, will increase the efficiency and profitability of the agricultural industry and obtain a synergistic effect in the form of socio-economic efficiency and environmental safety of production. In our opinion, this will contribute to the development of sustainable agriculture and the production of environmental products. Full article

The social impacts of prevailing circular economy (CE) strategies remain under-researched despite the considerable attention that CE has received from scholars and in industry. Existing CE indicators primarily focus on business models from a decision-making standpoint, overlooking consumer engagement and alternative solutions. Boasting one of the highest recycling rates globally, Taiwan faces challenges in optimizing collected resources. This study delves into recycling plastic waste by integrating consumer behavior within CE strategies, leveraging open-source resources and additive manufacturing technologies to align with the United Nations Agenda 2030, particularly Sustainable Development Goals (SDGs) 4 (Quality Education), 12 (Responsible Consumption and Production), and 13 (Climate Action). These resources facilitate the transformation of plastic waste into reusable materials. Employing an exploratory and participatory action research approach, this research uses the Precious Plastic Universe (PPU) database to identify potential resources from post-consumer polymer waste. Subsequently, it explores tools for converting collected waste into usable polymers. Lastly, the study investigates integrating collected polymer waste into student design projects to enhance creativity and problem-solving skills for sustainable development, employing additive manufacturing tools at the National Taiwan Normal University Department of Design. Thematic analysis of the data revealed several recurring patterns, including the role of consumer behavior in plastic waste generation, the development of creativity and problem-solving skills among students, and the challenges of working with recycled materials. These themes were observed in quantitative data (collected single-use polymers) and qualitative insights from student observations and interviews. Through thematic analysis, the study highlights key factors contributing to successful CE integration, providing a model for future educational and industrial applications of sustainable design.

This study focuses on two significant factors shaping university students’ perception of environmental sustainability. Those are (a) personal values, measured by the Portrait Values Questionnaire (PVQ) and (b) the usage of and proficiency in information technology. Personal values have been widely used to analyze individual perspectives toward various issues, including environmental ones. As contemporary social arrangements include significant influences from social networks and mobile phone usage, overall engagement with technology becomes an essential factor affecting university student attitudes and behaviors. While the individual impact of those factors can be found in the extant literature, we look into their interaction concerning university student pro-environmental attitudes, measured by the Revised NEP (New Ecological Paradigm) Scale, and their environmental self-efficacy. Our sample comes from the population of undergraduate business and economics students from Central and Southeast Europe, specifically Slovenia, Croatia, Bosnia and Herzegovina, Serbia, and Montenegro. We discuss our findings in the context of previous studies from the same regions and consider the unique socio-economic factors. The research results address Sustainable Development Goals 4 (quality education), 12 (responsible consumption and production), and 13 (climate action) by analyzing the factors contributing to university student pro-environmental attitudes and their self-efficacy in the context of their information technology usage and proficiency.

This analysis provides a comprehensive overview of current research regarding prefabricated construction costs, explained under three main categories: collaboration, intellectual basis, and research trends. The collaboration network covers country, institution, and journal distribution. Intellectual basis includes a cited journal, cited reference, and cited author, while research trends cover research category, keyword and keyword cluster analysis, and cited reference cluster. Through bibliometric analysis, we find that this field has garnered significant attention in the academic community and has developed rapidly. China dominates the field of prefabricated construction, with Curtin University, Chongqing University, and Deakin University being the leading research institutions, while Automation in Construction is the most cited journal. Although technology integration is widely regarded as a key means of cost optimization, its high implementation costs and complexity have limited its widespread application. The challenges of technology integration lie in the need to address high capital costs, complex management practices, and the demand for advanced technology integration, which have become significant barriers to the promotion of prefabricated construction. Moreover, current research also focuses on how to enhance risk control and management practices in cost management to promote sustainable development. Future research will focus on green and sustainable technologies, multidisciplinary engineering, energy and fuel, construction technologies to optimize prefabricated construction techniques, advance low-carbon building practices, and improve decision analysis and risk management. The key factors influencing costs include technological factor, policy factors, market and environmental factors, and organizational management. By systematically controlling these factors, cost pressures can be effectively alleviated, construction efficiency improved, and the sustainability of prefabricated buildings enhanced. This study not only provides a comprehensive analysis of the current state and trends in research on the costs of prefabricated construction but also highlights the critical role of technological innovation, policy optimization, and interdisciplinary collaboration in promoting the sustainable development of prefabricated construction globally.

Retrofitting existing buildings to be more energy-efficient is a tremendous contribution to the sustainability of society. The application of photovoltaic integrated shading devices (PVSDs) accords with this ambition by blocking out unwanted radiant heat gain and generating clean electricity. The deployment of PVSDs needs sensible design strategies to optimize the production of renewable energy while retaining the aesthetic quality of the built-up environment, especially in historic campuses. The concept was tested in a case study of buildings in South China University of Technology (SCUT) using Ladybug 1.4.0 and PVsyst 7.2, utilizing the existing “Xia’s shading” design method in historical environments and optimizing the design from the perspective of photovoltaic performance. Firstly, the photovoltaic (PV) panels were integrated as architectural components, and the parameters were incorporated into a mathematical equation based on “Xia’s shading” design method. This was followed by the assessment of the solar energy harvesting potential based on simulated annual solar irradiation values. Lastly, the PV panels’ solar irradiation potential under these different parameters was shown in figures to identify the optimum parameters combination for PVSD applications. The proposed methodology could evolve as a design tool and thus further assist in promoting the large-scale adoption of PVSDs in retrofit projects. Full article
