Unlike diesel generators or energy storage systems, photovoltaic (PV) arrays lack inherent rotational inertia and have output limitations due to their operational environmental dependencies. These characteristics restrict their suitability as primary power system backbone components. This study proposes a grid-forming (GF) control strategy for PV inverters in low voltage grid (LVG) using a model predictive control (MPC) approach. The proposed method introduces a novel predictive model accounting for capacitor dynamics to precisely regulate both AC-side output voltage and DC-side voltage. Furthermore, in this paper, P-V droop control replaces the traditional frequency regulation, achieving the real-time balance of DC/AC power and seamless sharing of multiple photovoltaic power sources. By integrating a modified cost function, the controller can flexibly switch between maximum power point tracking (MPPT) mode and power reserve mode according to varying output demands. The proposed strategy can provide advanced frequency stability, MPPT accuracy, and fast dynamic response under rapidly changing solar irradiance and load conditions. Simulation and experimental tests are carried out to validate the effectiveness of the proposed strategy. Full article

The article compares the young generation’s perspectives on social and environmental problems in Greece and Poland. We examine the visions of young generation representatives for solving these problems and their role in developing sustainable enterprises. A quantitative analysis was conducted using a k-means clustering algorithm in Python to analyze youth perspectives on sustainable enterprises in both countries. The method offers several benefits, including uncovering unexpected patterns, simplifying the data, and highlighting shared views across both countries. The results show that the youth in Greece and Poland widely support the inclusion of social and environmental considerations into business strategies, and despite some differences in the strengths of opinions, they agree that businesses should integrate sustainability into their mission. However, different clusters reveal varying levels of youth knowledge and awareness. Young people believe that businesses should prioritize sustainability, but acknowledge the difficulty of balancing profits with social and environmental goals. Financial support, specific skills, and experience are necessary for establishing sustainable enterprises. An enabling environment and youth empowerment are critical for promoting youth’s sustainable entrepreneurship. Future research could focus on the enabling factors that impact the willingness of youth to engage in sustainable entrepreneurship and on the ways and tools to provide necessary support.

With the increasing global focus on sustainable development, circulating fluidized bed (CFB) boilers, as highly efficient and low-pollution combustion equipment, play an important role in energy production and environmental protection. However, the combustion efficiency and emission control of CFB boilers still face challenges, and there is an urgent need for multi-objective optimization through advanced technologies to support the goal of sustainable development. This study proposes an intelligent framework integrating Bidirectional Temporal Convolutional Network (BiTCN) and Hybrid Dung Beetle Optimizer (HDBO) for multi-objective optimization of combustion efficiency and NOx/SO₂ emissions in CFB boilers. The BiTCN model captures bidirectional temporal dependencies between dynamic parameters (e.g., air-coal ratio, bed temperature) and target variables through operational data analysis. Three key improvements are implemented in DBO: (1) Chaotic initialization via sequential pattern mining (SPM) enhances population diversity and spatial coverage; (2) The osprey optimization algorithm (OOA) hunting mechanism replaces the original rolling update strategy, improving global exploration; (3) t-Distribution perturbation is applied to foraging beetles in later iterations, leveraging its “sharp peak and thick tail” characteristics to dynamically balance exploitation and exploration. Experimental results demonstrate 0.5–1% combustion efficiency improvement and 15.1%/30% reductions in NOx/SO₂ emissions for a typical CFB boiler. Full article

Temporary use of space in degraded areas is gaining significance in spatial planning due to limitations and conflicts stemming from traditional models that overlook social (soft) environmental components. This article addresses the lack of socio-ecological indicators in contextual analyses that precede planning processes in degraded areas. Using a plural case study approach across sites in Portugal and Slovenia, it combines primary data from semi-structured questionnaires and terrain analysis with secondary sources. The findings reveal that only specific types of temporary uses foster dynamic and adaptive social networks among stakeholders. These networks enhance the social and environmental sustainability of urban areas, particularly when socio-ecological indicators are refined to account for informal practices, community engagement and cultural value. Furthermore, the study highlights how these practices contribute to social sustainability by supporting inclusive governance models and stimulating local economies. A key finding of the study is the identification of a strong link between social networks and environmental sustainability, highlighting the need to incorporate updated socio-ecological indicators into spatial planning for degraded areas. Temporary uses are not merely stop-gap solutions but also strategic tools for cultivating sustainable urban areas. Full article

Enhancing public service efficiency is crucial for the Chinese government to ensure sustainable economic development. This study compiles data from 288 cities in China from 2011 to 2022 to construct an evaluation framework for the digital economy and public service efficiency. It also develops relevant econometric models to examine their impacts and underlying mechanisms. The results show that the digital economy significantly boosts local public service efficiency, with a more pronounced effect in cities with high or low initial efficiency levels and a less pronounced effect in those with moderate efficiency. The positive moderating roles of the political environment, government autonomy, urban innovation capacity, and social attention are also observed. This study suggests that local governments develop adaptive digital roadmaps to promote the digital economy and enhance public service efficiency. These findings enrich our understanding of how the digital economy influences public service efficiency and offer valuable insights for enhancing public service efficiency. Full article

Macroeconomic indicators are essential measures that reflect the overall economic wellbeing of a region or country and have a significant impact on investment decisions. The data on macroeconomic indicators for Turkish development regions facilitate a comparison of macroeconomic performance between these regions. This kind of analysis can help enhance the development levels of the regions while ensuring resources are used efficiently. This study compares the macroeconomic performance of Turkish development regions between 2019 and 2022 using a hybrid multi-criteria analysis method. A total of 26 regions were evaluated based on seven criteria: GDP, GDP per capita, employment rate, number of enterprises, export, unemployment rate, and import. The criteria were weighted using the Step-Wise Weight Assessment Ratio Analysis (SWARA) method and ranked using the Combined Compromise Solution (CoCoSo) method. This study addresses a gap in the literature by analyzing the macroeconomic performance of Turkish regions, aiming to reduce economic disparities. The results showed that the Istanbul region had the best performance over the 4-year period, while Eastern Anatolia experienced a consistently declining performance, ranking last. Some regions had fluctuating performances, while others maintained steady outcomes. This study advances research by offering a more reliable and comprehensive analysis, thereby contributing to the improvement of future studies on regional economic development. Full article

The ecological value of cultivated land carries clear intergenerational implications, requiring a fair allocation mechanism across the full life cycle to address market failures caused by intergenerational externalities. This study constructs an intergenerational allocation model of cultivated land ecological value based on the Diamond framework. The intra-generational consumption elasticity coefficient is derived using the Tapio decoupling theory, with the ratio of cultivated land quantity change to per capita net income change as the core indicator. Statistical data from Lezhi County (1984–2022) are used for empirical analysis. The fitted elasticity coefficient shows a steady decline and eventually converges to zero, indicating a weakening willingness of the current generation to consume ecological value, thus supporting the logic of preserving value for future generations. A simplified Pearl growth curve is then used to construct the development stage coefficient, representing the evolving realization of ecological value among future generations. Engel coefficient forecasts based on the GM(1,1) model enable year-by-year estimation of ecological value allocation to future generations. The results show that (1) the ecological value of cultivated land in Lezhi County is estimated at CNY 65,498,230/ha, (2) the proposed model effectively simulates intergenerational value allocation, (3) decoupling theory supports the hypothesis of equal intergenerational sharing, and (4) the development stage coefficient curve provides a dynamic perspective on long-term ecological value realization. This research offers a data-driven modeling approach that enhances both the fairness and the efficiency of land governance, contributing methodological support for sustainable cultivated land protection and ecological compensation policies.

Flood events have become more frequent as a result of seasonal changes, global warming, and changes in sea level. In terms of basin management, it is necessary to know the hydrodynamics of the basin in order to produce faster solutions in emergency action plans. The Filyos River is one of the two most important floodplains in the western Black Sea basin and has so far only been analyzed to a limited extent using modern hydrological and hydraulic models. In order to analyze the flood dynamics and determine the flood risks in the Filyos River. In this context, flood hydrographs, rainfall depths, peak flows, and excess water volumes were calculated for different return periods (2, 5, 10, 20, 50, and 100 years) using HEC-RAS, HEC-HMS, and Hyfran Plus software. The analyses showed that the rainfall depth and peak flow rate increased significantly as the return period increased. It was also observed that although the volume of precipitation increased, the amount of water converted into surface runoff remained limited due to infiltration and other losses. The results of the study contribute to the identification of high flood-risk areas in the Filyos River basin, the improvement of flood prevention infrastructure, and the development of sustainable water management policies. Analyses using modeling tools such as HEC-RAS and HEC-HMS provide a scientific basis to help local governments and decision makers strengthen flood prevention strategies, update risk maps, and make emergency response plans more effective while making flood scenarios more reliable.

In this work, a battery active grouping equalization control strategy based on model predictive control (MPC) was proposed, which can promote cell consistency, equalization speed and energy loss during the battery equalization process. The dynamic group equalization topology based on reconfigurable circuits can achieve dynamic grouping. Using a battery state observation estimator and the MPC controller, multiple non-adjacent cells can realize simultaneous equalization in a single equalization process. An algorithm is designed to determine the optimal energy transfer direction and the optimal equalization current. The objective function of this algorithm incorporates weight coefficients that represent the relative importance of equalization time and energy loss. Simulation tests are conducted to evaluate the battery pack state-of-charge (SOC) root mean square, average temperature, and equalization time under various weight coefficients. Compared with two other traditional equalization control strategies, the proposed strategy reduces the equalization time by 43.93%, decreases the battery pack SOC variance by 50.18%, and improves the energy transfer efficiency by 0.59%.

This paper presents a joint optimization framework for multi-period planning in a Manufacturing–Remanufacturing–Transport Supply Chain (MRTSC), focusing on carbon emission reduction and economic efficiency. A novel Mixed Integer Linear Programming (MILP) model is developed to coordinate procurement, production, remanufacturing, transportation, and returns under environmental constraints, aligned with carbon tax policies and the Paris Agreement. To address uncertainty in future demand and the number of returned used products (NRUP), a two-stage approach combining forecasting and optimization is applied. Among several predictive methods evaluated, a hybrid SARIMA/VAR model is selected for its accuracy. The MILP model, implemented in CPLEX, generates optimal decisions based on these forecasts. A case study demonstrates notable improvements in cost efficiency and emission reduction over traditional approaches. The results show that the proposed model consistently maintained strong service levels through flexible planning and responsive transport scheduling, minimizing both unmet demand and inventory excesses throughout the planning horizon. Additionally, the findings indicate that carbon taxation caused a sharp drop in profit with only limited emission reductions, highlighting the need for parallel support for cleaner technologies and more integrated sustainability strategies. The analysis further reveals a clear trade-off between emission reduction and operational performance, as stricter carbon limits lead to lower profitability and service levels despite environmental gains.

This study examined the potential for developing community-based homestays in Nigeria. Community-based homestays are a sustainable form of tourism that has the capacity to promote the Sustainable Development Goals (SDGs). With its abundant natural and cultural resources, Nigeria has not yet fully utilized these potentials for community-based homestays, which could serve as a strategy for the sustainable development of local communities facing livelihood challenges. Stakeholder theory serves as the theoretical foundation for this study, particularly in its application to a nascent concept. We proposed a framework for effective tourism development in Nigeria, focusing on acceptability, feasibility, and potential outcomes. Qualitative research was conducted through focus group discussions (FDGs) with purposively selected tourism stakeholders, including academia, tour operators, NGOs, and local communities, and further analyzed thematically. The study emphasizes that embracing stakeholder theory rather than relying on a top-down approach is crucial for effectively addressing the varied concerns of key participants before launching community-based homestay tourism. This approach seeks to maximize benefits while minimizing challenges. The result shows that developing community-based homestay tourism in Nigeria is achievable if all stakeholders work together to create supportive tourism policies and agree on a collaborative management framework for the initiative. Furthermore, it is essential to consider the needs of residents by including them in the homestay management committee. Local communities should receive sufficient funding, and effective marketing strategies must be put in place to promote the initiative. To ensure acceptance of homestay tourism among local communities, it is vital to communicate its benefits to potential operators, respect local cultures, and guarantee that economic gains are shared fairly.

In order to address the theoretical deficiencies present in the current literature regarding the willingness to utilize shared transportation—specifically the fragmented influencing factors and the ambiguous cultural regulatory mechanisms—this research employed a meta-analytic methodology. Adhering to the PRISMA guidelines, a systematic screening of 35 empirical studies was conducted (17 in Chinese and 18 in English), which collectively examined 21 potential predictor variables. Following the execution of heterogeneity tests and assessments of publication bias, a random-effects model was applied for the analysis. The results reveal that attitude, subjective norms, and performance expectations exhibit medium effect sizes, while perceived behavioral control, social influence, and trust show weak effects. Conversely, perceived risk is found to have a significant negative impact. Further analysis of moderating effects indicates that collectivist cultures significantly reduce the strength of the effects of subjective norms (Δβ = −0.047) and social influences (Δβ = −0.139). Additionally, the influence of subjective norms is more pronounced in cultures characterized by low uncertainty avoidance (0.371 vs. 0.265). This study offers a theoretical framework for the cross-cultural adaptation of shared transportation systems and establishes an empirical basis for the differentiated development of sustainable urban transportation policies.

This study analyzes the intersection of energy, urban planning, decarbonization, and sustainability as a central axis for addressing urban development challenges in Latin America. A systematic search of the Scopus database selected 509 articles published between 2019 and 2024. The documents were thematically classified into urban planning (274), energy (79), and decarbonization (147), identifying only 10 studies that simultaneously integrate at least two of these dimensions in Latin American contexts. While this sample of 10 articles does not allow for generalizations about the region, the article selects representative cases to contextualize the type of research conducted, rather than offering extrapolable results. An exploratory multivariate analysis was applied to identify patterns, thematic gaps, and convergence trends, including Principal Component Analysis (PCA) to reduce the dimensionality of the set of key concepts and Hierarchical Clustering (HCC) to group terms according to their semantic proximity. These results are complemented by co-occurrence and thematic concentration maps generated from keywords extracted from the selected articles. The findings reveal a low level of integration among the topics analyzed, justifying the need to establish new lines of interdisciplinary research. The study proposes a replicable analytical tool that guides future regional research and contributes to the achievement of the Sustainable Development Goals, especially SDG 7 (Affordable and Clean Energy), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action).

The rapid pace of urbanization has led to severe urban problems, with urban renewal emerging as an effective strategy to mitigate them. The City Betterment and Ecological Restoration (CBER) pilot scheme was an experimental policy aimed at urban renewal. Based on an optimized propensity score matching difference-in-differences model, the impact of the CBER pilot scheme on urban disease was examined. The results were threefold. (1) The CBER pilot scheme significantly alleviated urban disease in pilot cities. (2) The impact of the CBER pilot scheme was more pronounced in eastern and central regions of China, as well as in cities with high economic development, robust government capacity and abundant human resource. (3) Industrial structure optimization, infrastructure development and consumption upgrading were all effective pathways for mitigating urban disease through urban renewal.

Food waste poses critical environmental, economic, and social challenges, with consumer behavior recognized as a key leverage point for intervention. Packaging plays a vital role in preserving food quality and reducing waste, yet its behavioral influence on household food waste (HFW) remains underexplored. This review systematically examines 52 studies investigating the impact of food packaging—excluding storage/date labeling—on consumer food waste (CFW) behaviors. Using a structured methodology, we classified studies by methodological design, geographic coverage, food types, and focal packaging features. The analysis reveals a dominant reliance on consumer surveys and short-duration diaries, with limited application of rigorous experimental methods. Geographically, the English-language literature is skewed toward high-income countries, particularly Australia and Europe, with notable gaps in regions such as Asia and Africa. Moreover, despite U.S. households discarding approximately 40% of their food, research coverage remains limited. The findings also expose a misalignment between research focus and consumer-perceived importance of packaging features; attributes such as transparency, grip/shape, and dispensing mechanisms are frequently rated as important by consumers but are under-represented in the literature. This review contributes by identifying these gaps, synthesizing behavioral evidence, and offering a roadmap for future research and design innovation. By better aligning packaging functionalities with real-world behaviors, this work supports the development of consumer-informed solutions to mitigate HFW and promote sustainable food systems.

Transportation agencies face increasing challenges in identifying and prioritizing which infrastructure assets are most critical to maintain and protect, particularly amid aging networks, limited budgets, and growing threats from climate change and extreme events. However, existing prioritization approaches often lack consistency and fail to adequately incorporate diverse stakeholder perspectives. This study develops a systematic, stakeholder-informed method for ranking transportation assets based on their criticality to the overall transportation system. As a novel approach, we use the analytical hierarchy process (AHP) and present a case study of the applied approach. Six criteria were identified for ranking assets: annual average daily traffic (AADT), redundancy, freight output, roadway classification, Social Vulnerability Index (SoVI), and tourism. Stakeholder input was collected via an AHP-based survey using pairwise comparisons and translated into weighted rankings. Thirty complete responses (13.2% response rate) from experts (i.e., engineers, analysts, planners, etc.) were analyzed, with the resulting ranks from highest to lowest priority being AADT, redundancy, freight output, roadway classification, SoVI, and tourism. Stability analysis confirmed that rankings were consistent with a minimum of 15 responses. The resulting method provides a practical, replicable tool for agencies to perform statewide vulnerability/resiliency assessments ensuring that decision-making reflects a broad range of expert perspectives.

Thermal stress due to high temperatures has different negative effects on citizens as it generates a decrease in physical capacity and causes cardiovascular and respiratory alterations, which is especially true for pedestrians. In this paper, using a drone, routes for pedestrians with the best thermal comfort were traced between the different headquarters of the Simón Bolívar University (Barranquilla, Colombia). Maps were created for three time intervals, from 10 a.m. to 1 p.m., from 1 to 2 p.m. and from 2 to 3 p.m., and variations in temperature and relative humidity of both natural and artificial shadow areas were identified. The routes with the best thermal comfort were those with natural shade that presented ca. 3 °C less than the unshaded areas. The predominant trees’ genera in most of the traced pedestrian routes were Arecaceae (palm), Tabebuia (purple oak), Mangifera (mango), and Delonix (red acacia). Some of them lose their leaves between March and June, which gives rise to an increase in the temperature along those routes. The developed cell phone application allows for the selection of walking environments with the best thermal comfort, favoring the mobility of the pedestrians along the considered area. Full article

Since the early 2000s, sustainable development in agriculture has attracted substantial political attention, institutional support, and financial commitment, raising expectations for tangible outcomes. Yet, measurable progress remains uneven. As a leading food exporter, Brazil, in particular, has come under global scrutiny for practices deemed unsustainable—such as deforestation, excessive use of agrochemicals, and socio-environmental conflicts—despite its agricultural sector being a vital contributor to global food security. To provide policymakers with a robust monitoring tool, this study develops a nonlinear regression model that quantifies rural sustainability across economic, social, and environmental dimensions. We selected seven indicators—gross value added, average rural income, life expectancy, schooling years, preservation-area deficit, legal-reserve deficit, and water-scarcity deficit—to compute individual sub-indexes. These are combined into a composite rural sustainability index and applied to data from 141 municipalities in Mato Grosso. The results demonstrate that only municipalities achieving high and balanced scores in all three pillars can be deemed sustainable. Our framework contributes to the growing body of triple-index methodologies by offering a replicable, statistically robust tool tailored to agrarian contexts. It provides actionable insights for regional decision-makers aiming to balance productivity, environmental preservation, and social well-being in agricultural frontier regions. Full article

The rapid expansion of shale gas development has revolutionized global energy markets, yet it has also introduced substantial environmental challenges, particularly concerning groundwater resources. This comprehensive review systematically examines the multifaceted impacts of shale gas extraction on groundwater, with a focus on contamination mechanisms, pollutant sources, and mitigation strategies. The study identifies key operational stages—exploration, drilling, hydraulic fracturing, and flowback—as potential sources of groundwater contamination. Inorganic pollutants, including heavy metals and radionuclides, as well as organic compounds such as hydrocarbons and chemical additives, are identified as primary contaminants. The review critically evaluates current wastewater treatment technologies, including reinjection, internal reuse, and advanced desalination methods, highlighting their efficacy and limitations. Additionally, the study proposes a refined environmental management framework that integrates wellbore integrity optimization, enhanced shale gas wastewater treatment, and stringent monitoring protocols. The adoption of clean fracturing technologies and renewable energy applications is recommended to minimize environmental footprints. By establishing comprehensive baseline data and robust pollution monitoring systems, this research provides a scientific foundation for sustainable shale gas development, ensuring the protection of groundwater resources. This review emphasizes the imperative of balancing energy security with environmental sustainability, offering actionable insights for policymakers, industry stakeholders, and environmental scientists.
