Natural ventilation is deemed as one of the most suitable cooling strategy especially for hot humid climate. Natural ventilation relies on outdoor condition and requires space to provide air flow. Providing space for air flow is in hot humid climate with high density, vertical void is regarded as one of the best design for enhancing passive ventilation performance. This review synthesizes the design parameters of vertical void in hot humid climate as a method to enhance passive ventilation performance. The study uses bibliometric analysis and systematic review to analyze research trend and synthesize the design parameters from selected relevant publications. The results shows that vertical void designs are highly effective in improving passive ventilation in multi-story residential buildings. Various design variables such as aspect ratio, building height, and building to void ratio are paramount in improving ventilation performance. Strategically designed openings can maximize airflow by leveraging windward and leeward ventilation dynamics. Smaller void aspect ratio enhances ventilation efficiency across various void types, while taller chimneys increase air circulation through the stack effect.

The challenge of high energy consumption and carbon emissions within China’s construction industry has become increasingly urgent, as over 40% of buildings are still non-energy efficient. The multifaceted nature of systems involved in building retrofits results in a complex project, with barriers in both retrofit design and construction becoming increasingly evident. This research comprehensively assesses the common barriers in building retrofits and investigates the potential for integrating energy-efficient retrofits with information flow modeling from an interdisciplinary perspective. In order to pinpoint the main barriers hindering building retrofits, this study employs the bibliometric software VOSviewer. The analysis uncovers that the primary obstacles to energy-saving renovations are categorized into technical, economic, environmental, and other barriers. These barriers are characterized by a high degree of specialization, the inadequate integration of information, and limited collaboration among stakeholders. Subsequently, a qualitative literature review was conducted following the PRISMA methodology, which screened 40 key sources. The following conclusions were drawn: (1) The design of energy-saving renovation processes is impeded by the limited professional perspectives within the construction industry, which restricts the practical applicability; (2) Decision making for energy-saving renovations encounters notable professional barriers and suffers from inadequate information integration; (3) There is a lack of clarity regarding information needs during the implementation phase, and no effective platform exists for information coordination; (4) Risk analyses in complex energy-saving renovations largely depend on expert interviews, lacking robust scientific tools. These findings highlight that knowledge gaps and information asymmetry are the central challenges. To tackle these issues, this paper suggests the implementation of an information flow model that integrates the IDEF0 and DSM for building energy-saving retrofit projects. The IDEF0 model can clearly describe the interaction relationship of all expert information through functional decomposition, while the DSM can show the dependency relationship and information flow path among specialties through the matrix structure. This model is anticipated to enhance professional information integration and collaboration. It is proposed that improved information integration and collaboration under this framework will significantly promote the advancement of professional generative AI.

Green innovation (GI) has attracted growing interest in academia, society and business due to its importance for environmental protection, quality of life, environmentally friendly products and economic results, especially among small and medium-sized enterprises (SMEs). Consequently, given the vast literature, a bibliometric analysis of GI in SMEs is presented to evaluate their conceptual structure using Scopus and Web of Science databases through performance and bibliometric mapping with VOSviewer and R software. The results show that this topic is a growing area of research, with 496 articles developed by 1373 authors, 218 journals and 63 countries. The structure shows that the main research topics relate to sustainable business development, green business transformation, sustainable business innovation and performance, sustainable production, barriers, drivers and outcomes, eco-innovation and sustainability, and innovation and knowledge management. This work offers updated and exhaustive information on advances in this field that serve as a guide for SMEs to make informed decisions about innovation strategies, as well as more effective practices and lessons learned from other similar companies. In turn, governments can take these results and design policies and programs to support GI. Finally, this article highlights gaps in the literature that suggest possible avenues for follow-up studies.

Although life cycle assessment (LCA) as a method and framework has been extensively examined in the scientific literature, a new emphasis is put on integrating evolving spatiotemporal conditions of the analysed system, aiming to promote a more robust assessment through dynamic LCA. However, dynamic LCA methodologies remain inconsistent across multiple aspects, including on time-dependency, dynamic parameters, and links with other widely applied tools, such as material stocks and flows analysis or geographic information systems. Focusing on the four main phases of the LCA framework, this work presents a systematic review of the latest scientific literature reporting on prospective LCA modelling of buildings, while covering at least one dynamic parameter, such as the decarbonisation of the energy mix. First, this research presents the bibliometric structure of 64 published documents on the dynamic LCA of buildings, through four network visualisation maps. Then, it identifies a sample of 218 documents through the literature review method, and deeply analyses a sub-sample of 34 documents to systematise the emerging knowledge on dynamism in LCA as applied to buildings. We need a more comprehensive dynamic LCA modelling framework that can assess environmental performance of multiple building types, at a high level of spatial and temporal detail. Such framework should be able to integrate dynamic parameters in a simplified manner, and allow flexible time horizons and spatial scopes. Such framework should be able to quickly provide modelling results that may inform decision-making processes in finding solutions towards the challenges of resource depletion and climate change.

This study presents a comprehensive analysis of the evolution and challenges of Environmental Management Accounting (EMA) adoption across diverse industries and regions over the past two decades. Through a bibliometric analysis, this study categorizes the literature into three distinct periods, each elucidating crucial developments in EMA practices from initial theoretical formulations to their strategic integration with corporate sustainability and circular economy frameworks. The recent period particularly focuses on identifying the multifaceted challenges in EMA adoption, encapsulated in the newly developed “EMA adoption and application issue framework.” This framework not only categorizes but also visually represents systemic barriers such as regulatory constraints, organizational and cultural resistance, economic and technical obstacles, and the influence of external market forces. The analysis reveals significant regional disparities in EMA research, with a notable lack of contribution from European Union countries compared to active regions such as Australia, South Africa, and Southeast Asia, suggesting a critical need for strategic interventions to enhance EMA research and practical implementation in the EU. These findings advocate for more robust regulations, enhanced managerial commitment, and international collaboration to improve EMA adoption rates. This study aims to advance the understanding of EMA’s implementation challenges and foster dialog among academics, policymakers, and practitioners to overcome these barriers and enhance the integration of EMA into sustainability strategies globally.

The study aimed to determine short-term crop rotations’ economic and energy efficiency with varying sunflower saturation. The economic and energy efficiency of crop rotations saturated with sunflower under the conditions of the Left-Bank Forest-Steppe region of Ukraine was calculated using technological maps and prices as of 2024. The study employed the following methods: bibliometric analysis – a review of other researchers’ findings on the economic and energy efficiency of sunflower cultivation; grouping – an assessment of the economic and energy effects of varying sunflower saturation in crop rotations; and monographic – the generalisation of the results. The optimum sunflower share in crop rotations was found to be 20% and 40%, at which the production cost remained consistently high at 1,218.0-1,240.8 USD/t. Increasing the sunflower share to 60% led to a decline in the production cost, not only for other crops but also for the sunflower itself. This negatively impacted overall price stability, reducing crop competitiveness and the economic efficiency of crop rotations. Winter rye exhibited the lowest production costs among all crops, regardless of the crop rotation, at 268.9-321.1 USD/ha. The production costs of soybeans and winter wheat remained stable irrespective of sunflower share, at 413.5 USD and 553.7 USD, respectively, indicating their adaptability. A 20% sunflower share in the crop rotation exhibited the highest energy intensity at 63,348 MJ/ha, while a 60% saturation slightly reduced this figure to 63,279 MJ/ha. However, the 60% sunflower saturation resulted in lower energy consumption compared to other crop rotation options, at 30,293 MJ. These findings indicate the high efficiency of crop rotations with a 60% sunflower share, as evidenced by the energy efficiency ratio of 2.65. As a result of implementing the optimised crop rotation system across 78.9 hectares, sunflower seed yields increased by 0.16 t/ha compared to traditional practices. This improvement led to an additional 1,046 UAH/ha in net profit and a 25.6% increase in production profitability.

The peri-urban area represents a transitional zone between rural and urban landscapes, characterized by a mix of village-like and city-like features in physical form, social activities, and development patterns. This article provides an overview of peri-urban landscapes from a geographic perspective, based on a bibliometric analysis of research published from 2000 to 2023. Using data from the Scopus database, the study analyzed 118 publications with 3,464 citations, identifying 2014 as the peak year with 14 publications. The United States emerged as the most influential country, contributing 26 publications and maintaining 20 international collaborations. The research highlights that peri-urban areas are dynamic spaces influenced by geographic perspectives on study areas, models, scales, landscapes, development, and transformation processes. These areas are marked by social, economic, environmental, and spatial diversity. The study emphasizes the importance of geospatial technologies in exploring sustainable development strategies and calls for an interdisciplinary approach to address global challenges such as economic growth, land use changes, and urban planning in peri-urban regions.

Today, the world is increasingly concerned about energy and environmental challenges, and the search for renewable energy sources has become an unavoidable priority. In this context, Elaeis guineensis (better known as the African oil palm) has been placed in the spotlight due to its great potential and specific characteristics for the production of alternative fuels in the search for sustainable energy solutions. In the present study, bibliometric and co-occurrence analyses are proposed to identify trends, gaps, future directions, and challenges related to the production of bioethanol and hydrogen from oil palm rachis, using VOSviewer v.1.6.20 as a tool to analyze data obtained from SCOPUS. A mapping of several topics related to bioethanol and hydrogen production from oil palm bagasse or rachis is provided, resulting in contributions to the topic under review. It is shown that research is trending towards the use of oil palm rachis as a raw material for hydrogen production, consolidating its position as a promising renewable energy source. The field of hydrogen production from renewable sources has undergone constant evolution, and it is expected to continue growing and playing a significant role in the transition towards cleaner and more sustainable energy sources, potentially involving the adoption of innovative technologies such as solar-powered steam generation. From an economic point of view, developing a circular economy approach to bioethanol and hydrogen production from oil palm rachis and waste management will require innovations in material design, recycling technologies, and the development of effective life cycle strategies that can be evaluated through computer-assisted process simulation. Additionally, the extraction and purification of other gases during the dark fermentation method contribute to reducing greenhouse gas emissions and minimizing energy consumption. Ultimately, the sustainability assessment of bioethanol production processes is crucial, employing various methodologies such as life cycle assessment (LCA), techno-economic analysis, techno-economic resilience, and environmental risk assessment (ERA). This research is original in that it evaluates not only the behavior of the scientific community on these topics over the past 20 years but also examines a less-studied biofuel, namely bioethanol.

Dam breach can trigger severe flood disasters, threatening life and property safety, and having long-term impacts on the environment, society, and the economy. Dam breach floods also contaminate water bodies, degrading water quality and its sustainability. This study analyzes the characteristics and trends of dam breach research using research findings included in the CNKI (China National Knowledge Infrastructure, Beijing, China) database and the Web of Science (WoS) core database. Bibliometric methods, including word frequency analysis, co-citation analysis, and clustering analysis, were applied to the retrieved data. Using the CiteSpace (v6.3.R2) visualization tool, the study conducted statistical analyses and generated maps for publication trends, research institutions, and research hotspots. The findings indicate the following. (1) From 2000 to 2023, the number of research outcomes has been continuously growing both domestically and internationally with significantly more foreign-language publications than Chinese ones. (2) Chinese research institutions, notably the Chinese Academy of Sciences and the Nanjing Hydraulic Research Institute, have substantial international influence. (3) In terms of research hotspots, Chinese studies focus on the failure mechanisms of earth-rock dams, while foreign studies emphasize dam breach flood flows. (4) Establishing numerical models has emerged as a common trend in both Chinese and foreign research. These insights help identify deficiencies in current methods and technologies, allowing for the proposal of more scientific strategies for dam safety assessment. Based on these conclusions, some insights are proposed with the aim of reducing the risk of dam breaches, ensuring sustainable water resource management and utilization, promoting environmental protection, and fostering harmonious socio-economic development.

Earthquake-induced landslides have always been a hot research topic in the field of geosciences. However, there have been few bibliometric analyses on this topic. To systematically understand the research status, this study is based on bibliometrics and extensively uses visualization analysis techniques. It combines quantitative and qualitative methods to conduct an in-depth analysis of 5 016 papers collected from the Web of Science (www.webofscience.com). The results revealed that: ①The number of papers on earthquake-induced landslides is steadily increasing, and is expected to continue to rise. ②Countries prone to frequent earthquakes have made significant contributions to the research on earthquake-induced landslides, and the frequent and effective cooperation among these countries has had a very positive impact on promoting landslide study. ③ Research on earthquake-induced landslides is no longer limited to the field of geology, and the future direction is to integrate knowledge and technical methods from multiple disciplines. In the research methods of earthquake-induced landslides, there is a gradual shift from “experience, theory” to “data-driven”. This study can provide researchers in this field with information on the core research forces, evolving hot topics, and future development trends of earthquake-induced landslides.

The objective of this research is to conduct a literature review from the bibliometric and systematic perspectives on fire in semiarid regions at a global level, focusing on the application of remote sensing in data acquisition. For this review, bibliometrics were used, in which the quantitative approach was valued, through Bibliometrix, through the RStudio software and the WordClouds software for the word cloud. The search string “fire AND in AND semiarid” was used. The literature review is a procedure that can be used to support scientific research, or when the research is characterized exclusively as bibliographic. The research was carried out using two databases (Web of Science and Scopus). A total of 927 articles were found, 560 from Scopus (Sco) and 367 from Web of Science (WoS). After analyzing the exclusion criteria for duplication using RStudio, 226 articles were excluded, leaving 698 documents. For the systematic analysis, the articles were separated into two groups: direct method and indirect method, with the indirect method being related to remote sensing. From this screening, 193 articles were classified as indirect method, 493 as direct method, and 8 articles were outside the research context. Southern Africa, Australia, China, and the United States were the ones that presented the largest number of studied locations, corresponding to 10, 35, 12, and 42 articles, respectively. It can be observed that at the beginning of the 21st century, there was an increase in the number of publications, specifically from 2005 onwards, with more than 10 articles being published per year. It can be seen how valuable these studies are to the scientific community, since they reveal the most widely used remote sensing products for fire studies in the semiarid region.

The Qinghai-Tibet Plateau (QTP) is prone to various types of natural disasters with extensive distribution and severe impacts. A systematic review of historical disasters and their spatiotemporal patterns on the QTP over the past century is crucial for a comprehensive understanding and assessment of disaster risks. By searching research articles on QTP disasters through the Web of Science Core Collection, Scopus, and Chinese Science Citation Database, this study collected 261 papers and conducted a bibliometric analysis to summarize the main disaster types and distribution patterns. We categorized QTP disasters into five major types (geological disasters, glacial disasters, meteorological disasters, hydrological disasters, and other disasters) and 15 subtypes. Furthermore, by integrating data from open platforms, published chronicles, yearbooks, and articles, we compiled a structured dataset of major recorded disaster events on the QTP in the past century, which documents the time, location, intensity, casualties, and direct economic losses of each event. This comprehensive, long-term dataset of QTP disasters surpasses existing open data in temporal coverage and completeness. The dataset will serve as a fundamental resource for disaster research, risk assessment, and prevention planning in the QTP region.

Due to the influence of climate change and human activities, slope water yield characteristics have changed, and the “activity” of water has begun to weaken, resulting in slope ecological degradation and river runoff attenuation. To carry out refined water system management and delay environmental degradation in the basin, it is necessary to accurately identify the slope water yield process and formulate the basin water yield baseline (BWYB) scientifically and reasonably. Based on bibliometric analysis and literature research methods, this paper systematically reviews the monitoring methods and monitoring elements of the water yield process in watersheds and slopes, expounds on the slope water yield process identification method, and also discusses the BWYB threshold and the control measures of slope water yield. Through a comprehensive analysis of the BWYB and a summary of the observation technologies for the water yield process, this paper offers a significant reference and basis for establishing a monitoring system for the evolution and regulation of basin hydrology, as well as for simulating and predicting basin water yield across various spatial and temporal scales.

This article conducts a systematic mapping and inductive analysis of existing work related to hydrogen energy policy in the Web of Science Core Collection from 1996 to 7 July 2023. First, based on bibliometrics, the research reveals the publication volume trends, influential contributors (countries, authors, organizations and journals). Second, bibliometric and content analysis were applied to vividly demonstrate the evolution of the research topic, discuss leading research topics, and provide valuable insights into issues that deserving appropriate attention in the future. The unequivocal role of policies in supporting the development of hydrogen energy is undeniable. In the future, the focal point of hydrogen energy policies should be concentrated on stimulating the creation of demand for green hydrogen, necessitating the effective evaluation of policy outcomes and ensuring the safety of hydrogen energy. Furthermore, the application scope of hydrogen energy extends beyond the transportation sector, holding potential for expansion into other high carbon-emitting domains. With the strengthening of international collaboration in hydrogen energy, considerations of energy justice and fairness are poised to become pivotal factors in cooperation, exerting a profound influence on the attainment of long-term development and environmental sustainability. These critical research directions will shape the future landscape of hydrogen energy policy and serve as an essential resource for policymakers, researchers, and stakeholders in this domain.

The coastal and marine landscape within national and international space is of significance for human systems, sustainable (economic) development, global changes, and pollution prevention. South Africa occupies a geostrategic position due to its vast maritime trade, extensive and well-endowed coastline, being a continental shelf, having territorial waters, and several exclusive economic zones. Significant research has been done in the coastal and marine space of the country, especially in marine protected areas, oceanography, marine biology, fisheries and aquaculture. As such, this study explores the emerging thematic areas in South Africa’s coastal and marine studies teasing out research gaps with the view of encouraging more collaboration and research work in such areas. The paper utilises a bibliometric analysis that is aided by the VOSviewer software analysis. The key findings are that common areas of coastal and marine research include natural sciences and marine biology. On the other end, gaps emerged concerning research on ocean economy, ocean literacy, Sustainable Development Goal 14, the newly crafted discourses on global governance on plastics pollution, and the United Nations Ocean Decade. The study is significant in that it broadens the scope of coastal and marine research in South Africa and contribute towards the attainment of the Ocean Phakisa, blue economy, 2030 Agenda for Sustainable Development, and Ocean Decade perspectives.

Nature-based solutions (NBS) are increasingly proposed as a response to the growing vulnerability of coastal areas to the risks of coastal erosion and flooding. These solutions rely on the functioning of ecosystems to mitigate the effects of coastal hazards. However, the ability of ecosystems to act as buffer zones is being compromised due to increasing urbanization in coastal areas. The implementation of NBS in urbanized coastal areas is becoming a major challenge for our societies, as coastal cities densely concentrate populations and valuable assets. This study has two main objectives: (1) to provide a structured overview of current NBS research and (2) to explore whether and how NBS are utilized in urban coastal risk management. A critical review of the literature serves as a foundation for understanding how NBS is conceptualized, identifies the factors contributing to the ambiguity of the term, and proposes five key elements for defining NBS. A systematic review of 3384 publications from Scopus shows that coastal issues represent a secondary focus in NBS research (14%). Coastal NBS studies primarily address coastal erosion and flooding exacerbated by sea level rise through natural coastal ecosystems. While urban issues related to climate change are at the heart of NBS research, the urban dimension has very little connection with coastal NBS. This article highlights the need for a multifaceted response to manage coastal risks in coastal cities, combining hard and soft engineering (hybrid solutions), inshore and offshore NBS, coastal and stormwater NBS, and regulating urbanization in flood-prone areas. The application of NBS in coastal risk management calls for incorporating natural coastline dynamics into land-use planning and rethinking our fixed modes of coastal occupation. This article provides keys to understanding the concept of NBS to facilitate its integration into coastal risk management plans.

The rapid evolution of the mechanical industry necessitates reliable and innovative materials. Metal matrix composites (MMCs) have emerged as a leading contender for performing vital roles in this field. Carbon nanostructures, such as graphene and carbon nanotubes (CNTs), are particularly well-suited as reinforcement materials in MMCs. It has been found by recent experimental studies that incorporating CNTs and graphene as reinforcements into metal matrix composites, such as aluminum, magnesium, titanium, nickel, and copper matrices, can significantly enhance the mechanical, thermal, and tribological properties of these materials. This is achieved through various mechanisms, including the restriction of grain growth, hindrance of dislocations, load transfer at interfaces, and mitigation of thermal expansion mismatch. The precise reinforcement and optimization of fabrication techniques have opened up new avenues for achieving uniform nanostructure dispersion and strong interfacial bonding, leading to substantial improvements in quantitative properties. Such advancements in material science hold great promise for the development of high-performance materials with enhanced properties that are vital for various applications, including aerospace, automotive, biomedical, and beyond. The addition of low-carbon nanostructures to polymer matrix, ceramic, and biocomposite systems has also been observed to elicit noteworthy multifunctional improvements. Reinforcing collagen with CNT fibers leads to better mechanical and electrical performance compared to using collagen alone. This critical review provides an insightful and data-driven analysis of the current state of carbon nanostructure (CNTs/graphene)-reinforced metal matrix and biocomposites based on an extensive literature evaluation. The review includes an in-depth examination of the optimized synthesis and processing techniques for CNTs and graphene MMCs, highlighting the impact of reinforcement on their mechanical, thermal conductivity, electrical conductivity, and functional properties. Continued work refining fabrication methods fully leverages their potent multi-functional enhancement capabilities.

The agro and allied sectors generate various wastes, including crop residues, seeds, peels, and husks, which, if not managed properly, can cause significant environmental harm. However, these wastes hold potential as valuable resources that can be transformed into useful components for food, nutraceutical, pharmaceutical, and bioenergy applications. This bibliometric study analyzes research trends, methods, and applications related to agro-waste valorization from 2000 to 2024. The analysis reveals a marked increase in the adoption of green extraction methodologies, such as supercritical fluid extraction and enzymatic extraction, with publications rising from 1 in 2001 to 78 in 2024. Key countries leading this research include India, Brazil, and China, while Portugal is notable for its high average citations per document, indicating impactful research contributions. Prominent journals in this field include “Trends in Food Science and Technology,” “Food Research International,” and “Waste and Biomass Valorization,” which focus on the extraction of bioactive compounds and their applications. The results highlight the potential of agro-waste for developing functional foods, packaging, and other value-added products, while also addressing challenges related to scalability, and variability in bioactive compound recovery. This study underscores the effectiveness of various extraction methods, including supercritical fluid extraction, hydro-methanolic extraction, and solid-state fermentation, in recovering bioactive compounds such as polyphenols, flavonoids, and antioxidants. Future research should focus on optimizing extraction methodologies, enhancing bioavailability, and exploring synergistic approaches to integrate agro-waste processing with renewable energy systems.

This study aimed to identify emerging trends and topics in strategic management and sustainable development research in the context of global disruptions, especially when they combine into polycrises, contributing to a state of uncertainty known as the non-ergodic world. The authors employed the Scopus database to collect and analyse academic literature from 2015 to 2023. Additionally, they reviewed United Nations reports to complement the academic data with a statistical analysis of the progress made in implementing the Sustainable Development Goals (SDG). The results revealed discrepancies in this progress, with advances in poverty eradication, responsible consumption and production and climate action. However, more progress is needed to reduce hunger, preserve life on land and below water, promote peace, establish justice and strengthen institutions. This lack of focus is also mirrored in the most cited academic research on strategic management and sustainable development. The analysed research experienced a 13.0 % annual growth, with an average of 26.9 citations from 84 countries. The bibliometric analysis identified further research areas, including sustainable economic development, business sustainability strategies, leadership, and the impact of global disruptions. Thus, reflecting the challenges of achieving the United Nations Agenda 2030 in the context of global disruptions, this study confirmed the increasing role of integrating sustainable development considerations into strategic management research and highlighted the need for more research and action to meet the SDGs.

In terrestrial ecosystems, plant leaves provide the largest biological habitat for highly diverse microbial communities, known as the phyllosphere microbiota. However, the underlying mechanisms of host-driven assembly of these ubiquitous communities remain largely elusive. Here, we conduct a large-scale and in-depth assessment of the rice phyllosphere microbiome aimed at identifying specific host-microbe links. A genome-wide association study reveals a strong association between the plant genotype and members of four bacterial orders, Pseudomonadales, Burkholderiales, Enterobacterales and Xanthomonadales. Some of the associations are specific to a distinct host genomic locus, pathway or even gene. The compound 4-hydroxycinnamic acid (4-HCA) is identified as the main driver for enrichment of bacteria belonging to Pseudomonadales. 4-HCA can be synthesized by the host plant’s OsPAL02 from the phenylpropanoid biosynthesis pathway. A knockout mutant of OsPAL02 results in reduced Pseudomonadales abundance, dysbiosis of the phyllosphere microbiota and consequently higher susceptibility of rice plants to disease. Our study provides a direct link between a specific plant metabolite and rice phyllosphere homeostasis opening possibilities for new breeding strategies.

Long-distance migrations of insects contribute to ecosystem functioning but also have important economic impacts when the migrants are pests or provide ecosystem services. We combined radar monitoring, aerial sampling, and searchlight trapping, to quantify the annual pattern of nocturnal insect migration above the densely populated agricultural lands of East China. A total of ~9.3 trillion nocturnal insect migrants (15,000 t of biomass), predominantly Lepidoptera, Hemiptera, and Diptera, including many crop pests and disease vectors, fly at heights up to 1 km above this 600 km-wide region every year. Larger migrants (>10 mg) exhibited seasonal reversal of movement directions, comprising northward expansion during spring and summer, followed by southward movements during fall. This north–south transfer was not balanced, however, with southward movement in fall 0.66× that of northward movement in spring and summer. Spring and summer migrations were strongest when the wind had a northward component, while in fall, stronger movements occurred on winds that allowed movement with a southward component; heading directions of larger insects were generally close to the track direction. These findings indicate adaptations leading to movement in seasonally favorable directions. We compare our results from China with similar studies in Europe and North America and conclude that ecological patterns and behavioral adaptations are similar across the Northern Hemisphere. The predominance of pests among these nocturnal migrants has severe implications for food security and grower prosperity throughout this heavily populated region, and knowledge of their migrations is potentially valuable for forecasting pest impacts and planning timely management actions.

As the population and urbanization continue to grow, we expect an increase in industrial demand, which will lead to higher water consumption and, consequently, the generation of substantial amounts of industrial wastewater (IWW). This presents significant environmental challenges that necessitate effective treatment solutions. This study addresses the gap in the existing literature by conducting a bibliometric analysis of 1,714 research papers on IWW treatment published in the Scopus database from 2015 to 2024. The findings indicate that over 59.7 % of these publications emerged within the past five years, with a peak of 244 papers published in 2022, reflecting an increased recognition of the necessity for effective IWW treatment approaches. The Journal of Water Process Engineering is identified as the leading journal in this domain. The analysis reveals that the majority of research is concentrated in the fields of chemistry and chemical engineering, with India and China contributing the highest outputs, at 11.79 % and 10.44 %, respectively. The University of Chinese Academy of Sciences is highlighted as a significant contributor, with seven publications and 74 citations, underscoring its prominence in IWW research. The studies indicate a focused interest in addressing various pollutants from industrial wastewater, including chemical oxygen demand (COD), dyes, and heavy metals. Furthermore, this body of research highlights a significant shift from traditional treatment methods toward integrated strategies that combine multiple techniques to enhance efficacy and sustainability in IWW treatment. Electrocoagulation, adsorption, and activated carbon are identified as the predominant treatment methods being explored for specific types of IWW, particularly textile and tannery wastewater. This research significantly contributes to the understanding of contemporary trends and advancements in IWW treatment, emphasizing the critical role of innovative methodologies in effectively addressing pollutant removal and promoting environmental sustainability.

Municipal solid waste (MSW) management has become a critical issue today, posing substantial economic, environmental, and social challenges. Identifying and analyzing dominant themes in this field is essential for advancing research and policies towards sustainable MSW management practices. This study aims to explore the key issues related to MSW management that have been addressed by both the scientific community and policymakers through funded projects. By doing so, the study seeks to guide the scientific community as a knowledge producer and the EU as a key funder. Two Latent Dirichlet Allocation (LDA) models were applied to analyze the themes from two corpora: one representing scientific literature and another focusing on EU-funded projects. Additionally, this analysis was complemented by a quantitative estimation of the similarity between the two corpora, providing a measure of alignment between the scientific community and policymakers. The results generally indicate that the two spheres are aligned and highlight the diversity of topics explored by the scientific community. Nevertheless, it is concluded that there are opportunities for further research on specific topics, such as leaching and the extraction of heavy metals. Additionally, the popularity of topics identified in European Union-funded projects has fluctuated considerably over time, focusing primarily on waste management rather than its prevention. In light of these findings, waste prevention emerges as a promising avenue for future EU-funded research initiatives.

This study highlights the significant potential of activated carbon (AC)-based materials in environmental remediation and energy production, particularly in converting carbon dioxide (CO2) and hydrogen (H2) into methane (CH4) and water (H2O) using transition metal-based catalysts. It emphasizes the role of porous AC in waste reduction and resource utilization, examining various applications of CO2 and evaluating environmental impacts. The research explores commercialization opportunities and specifically investigates CO2 methanation using AC-based materials. Using bibliometric analyses of 4196 articles from the Web of Science database, the study identifies a growing research interest in porous AC-related CO2 methanation from 2014 to 2024. The top three journals in this field are Environment Development and Sustainability, Biomass Conversion and Biorefinery, and Journal of Environment Science and Pollution. However, there is limited inter-institutional collaboration in this field, suggesting room for development towards commercializing sustainable CH4 production pathways. CH4 is highlighted as a crucial intermediate in industrial processes, and research directions are identified through co-occurring author keywords analysis. The study suggests the need for a comprehensive approach integrating AC materials into carbon-neutral energy processes while addressing the potential adverse effects of AC nanoparticles on biological and environmental factors. Ultimately, it clarifies the potential uses and commercialization prospects for porous AC materials, especially in conjunction with carbon capture and utilization technologies, promoting sustainable practices in energy production and environmental management.

Climate change presents profound challenges to marine ecosystems and fisheries, necessitating effective management and adaptive strategies. Simultaneously, marine fisheries exacerbate climate change by emitting greenhouse gases through fuel combustion and electricity consumption. This article reviews 142 studies on the bidirectional interactions between climate change and marine fisheries (ICCMF), utilizing bibliometric methods including co-occurrence network analysis, cluster analysis, and conceptual framework analysis to identify research trends, challenges, and gaps. The bibliometric analysis reveals an explosive growth in publications and patents related to ICCMF since 2020. The key themes in ICCMF research encompass: (a) the impacts of climate change on marine fisheries, (b) the contribution of marine fisheries to climate change, (c) stakeholder perceptions and responses to climate change, and (d) adaptive management strategies for climate-resilient fisheries. Notably, recent studies have increasingly focused on carbon emissions and carbon sinks in marine fishery industries, emphasizing the need for further research into carbon reduction practices to mitigate climate change. This review identifies several challenges, including geographical disparities, knowledge inequality, “parachute science” and “helicopter research,” issues with data quality and management, and inadequate capacity to adapt to climate change. Key research gaps include the limited representation of perspectives from the Global South, the absence of sustained partnerships, imbalances in research collaboration, restricted data accessibility and reliability, and an inadequate understanding of fisheries’ carbon emissions. This review provides valuable insights for researchers, policymakers, and stakeholders, highlighting the need for strategic management approaches to mitigate adverse impacts and promote marine ecosystem sustainability.

The Vehicle Routing Problem (VRP) not only poses a fundamental challenge in logistics and operations management but also plays a crucial role in mitigating environmental impact through the optimization of efficient and sustainable routes. The scientometric development proceeded in two stages: scientific mapping and network construction. In the first stage, a bibliometric analysis of publications indexed in Scopus from 2000 to March 2024 was conducted using the PRISMA and Tree of Sciences (TOS) methodology, selecting 364 relevant documents on “sustainable” and “Vehicle Routing Problem”. Recommended bibliometric procedures were applied, and Bibliometrix tools were utilized to integrate bibliographic information. In the second stage, a citation network was constructed using graph theory to identify key documents and research trends, analyzing indicators such as Indegree, Betweenness, and Outdegree. The results indicated a significant increase in publications on VRP and sustainability since 2013, highlighting international collaboration and the leadership of China and the United States. Key authors and journals in the field were also identified. Finally, research clusters were developed on electric vehicle routing optimization, optimization methods, routing problems, and logistical challenges, underscoring the cooperation between enterprises and sustainable logistics as key areas for future research.

Environmental concern is a significant driver of demand for sustainable initiatives, emphasizing the significance of green finance in academic research.

Therefore, the present study mounts the development and thematic evolution of green finance through a comprehensive bibliometric analysis. Using the Scopus database, we analyzed 887 articles to identify key trends, collaboration networks, and thematic clusters. It was found that China has made a significant contribution to academic literature and has had notable collaborations with South Asian institutions. The central themes are carbon emissions, green technology innovation, and renewable energy. The two advanced bibliometric tools, Biblioshiny and VOSviewer create thematic maps, co-citation networks, and keyword analyses to provide insights into the intellectual structure of green finance research. Based on this study, the most influential authors, major journals, and emerging research areas are pinpointed to offer a pathway for future research in this multidisciplinary domain. The study’s findings underscore green finance’s significant role in achieving sustainable development and promoting environmentally friendly initiatives.

Forest fires pose significant environmental challenges globally, profoundly affecting watershed hydrology. As human activities increase and climate change exacerbates, the incidence and severity of forest fires have escalated, leading to profound modifications in watershed hydrological behavior. This review synthesizes findings from numerous studies conducted between 1966 and May 2024, focusing on the short- and long-term effects of forest fires on watershed runoff, peak flow, sediment transport, and water quality. Key findings include significant increases in runoff volume and peak flow, with post-fire runoff in some regions increasing by up to 500 %. Fires also alter soil properties, reducing infiltration and increasing erosion. These changes persist over time, impacting groundwater recharge, baseflow, and water quality. Elevated levels of phosphorus, nitrate, and other pollutants in post-fire runoff present risks to aquatic ecosystems and human health, with potential for eutrophication and contamination of drinking water. The study highlights regional differences in hydrological responses to forest fires, with Mediterranean regions experiencing rapid runoff increases, while boreal forests exhibit more gradual hydrological changes. This review also discusses the methodologies employed, including hydrological models and remote sensing technologies, and outlines future research needs to address gaps in our understanding of fire-watershed interactions. Improved management strategies are essential to mitigate the hydrological impacts of increasing fire activity in forested regions worldwide.

Poly- and perfluoroalkyl substances (PFAS) are synthetic, highly fluorinated chemicals commonly used in products like water-resistant materials, personal care items, non-stick cookware, and cleaning agents. Due to the strength of their C[sbnd]F bonds, PFAS are extremely persistent in the environment, creating significant challenges for pollution control. Traditional degradation methods often prove ineffective, making adsorption a promising alternative for PFAS removal from contaminated water. Carbon-based adsorbents, valued for their sustainability and efficiency, are particularly effective for this purpose. This review provides a detailed analysis on PFAS properties and their removal using various carbon-based adsorbents, including activated carbon, biochar, graphene oxide, carbon nanotubes, and magnetic composites. Adsorption capacities of these materials were seen vary significantly, from as low as 10.7 mg/g for Fe3O4-hybrid biochar, to as high as 713.85 mg/g for functionalized graphene-based adsorbent, highlighting the superior adsorption efficiency of modified graphene adsorbents compared to traditional biochar and activated carbons. Most of these adsorbents fit the Langmuir isotherm model and pseudo-second-order kinetic model with high coefficient of determination, indicating efficient monolayer adsorption and strong interaction with PFAS. The review also explores different adsorption mechanisms, the effects of process parameters on adsorption efficiency, strategies for adsorbent regeneration, and concludes with a bibliometric analysis that highlights key research gaps. These insights are intended to guide future advancements in the development of effective, scalable PFAS remediation technologies using carbon-based adsorbents.

Emerging contaminants (ECs) include a wide range of substances whose presence may pose a risk to the environment and human health. Research on cytostatic pollutants is increasing because the exponential growth of cancer treatments leads to higher discharge of cytostatic contaminants with wastewater treatment plant effluents. This systematic bibliometric review shows 4166 publications within the topic of ECs and cytostatic drugs in water bodies since 1996, mainly in the category of Environmental Science. China, Spain and USA are the most productive countries nowadays and Europe has 41,6 % of the publications. Research topics have shifted from identifying the presence of ECs, in the period 1996–2012, to understanding their fate, distribution, and long-term impacts as well as on developing removal technologies, in the period 2012–2023. 29 main keywords have been identified and classified into four thematic groups: contaminants, analytical techniques, water bodies and treatments. Principal component analysis has integrated them into two principal components (PC). PC1 includes keywords within the groups of water bodies and treatments, and it reflects 70 % of the original data variance; while PC2 represents the analytical topic, and it represents 20 % of the variance. The co-occurrence networks of keywords, analysed by VOSviewer, show four clusters in both periods, with “emerging contaminants”, “pharmaceuticals”, and “personal care products” as the most important. “Contaminants” that appear in the first period have been substituted by “treatment plants” in the last decade. The keyword “personal care products” shows the highest increase (14-fold), higher than “emerging contaminants” (13 times) and “cytostatic drugs” (10 times). In recent years, the research interest on the formation of transformation products during water treatments and their risks has increased as shown by the higher importance of keywords such as “transformation products”, “risk assessment” and “toxicity”, as consequence of the development of advanced oxidation treatments.

Major sudden disasters, such as floods, earthquakes, and fires, often cause significant casualties. Emergency evacuation is crucial in mitigating these impacts. Different types of disaster incidents vary significantly in terms of impact scope, suddenness, and urgency. Each type of disaster possesses distinct characteristics, necessitating varying requirements for emergency evacuation. Consequently, we conducted a bibliometric analysis and visual mapping of evacuation processes in major natural disasters from 2004-2023, analyzing 7213 publications from the Web of Science database via VOSviewer and ArcGIS. Our study identified three developmental phases: an initial phase (pre-2011) with 1169 publications, a growth phase (2012-2018) with 2772 publications, and an expansion phase (post-2019) with 3335 publications. This study provides a comprehensive review and classification of emergency evacuation theories and methods in major disaster scenarios. It emphasizes the necessity of assessing the scope and intensity of different types of major emergent disasters, defining and simulating the affected behaviors of the influenced populations, and formulating differentiated emergency evacuation strategies accordingly. Keyword analysis reveals two main trends supporting these findings: an increasing focus on complex evacuation modeling and simulation techniques, manifested in the application of various simulation-optimized microscopic and macroscopic models such as cellular automata, social force models, agent-based models, pedestrian flow, and network flow models, enhancing disaster understanding and prediction capabilities; and the strategic development of tailored evacuation strategies for specific disaster contexts, thereby improving disaster response efficiency. Three key future pathways for safety evacuation research are outlined: refining evacuation behavior models for greater accuracy, improving the coordination of complex, multi-level evacuation procedures, and integrating indoor and outdoor evacuation strategies more seamlessly. It establishes a forward-looking framework for advancing safety evacuation studies in major emergencies.

The study explored rural livelihood sustainability in South Asia and Africa through a bibliometric analysis and systematic review approach. The purpose of the study was to identify the trend of scholarly discourse, the dominant themes that have attracted scholarly interest over the past decade, and to shed light on the emerging opportunities for enhancing rural livelihood sustainability. The study carefully selected 139 articles sourced from Scopus, Web of Science, Google Scholar, and other institutional websites. Our findings revealed noticeable growth in scholarly output over the past decade and identified some scholars with noteworthy contributions. Notably, it was found that the impact of climate change, drought, poverty, and food security on rural livelihoods has largely dominated the scholarly investigations over the period. However, the potentials of pyrolis, biochar, and dryland forestry for rural livelihood sustainability were found to be underexplored. In light of these insights, we recommend the scholarly community develop much interest in less explored areas that equally hold great potential for enhancing rural livelihoods. We also recommend that rural livelihood programming by policymakers must seek the integration of indigenous knowledge and be tailored to strengthen the resilience of rural households against the perils of climate change and weather variability.

Recent years have seen an increasing interest in 3D concrete printing (3DCP); however, its sustainability challenges, particularly regarding environmental concerns, require close attention. To mitigate sustainability-related problems of technology, new realm of research has emerged: sustainable 3DCP. However, this field currently lacks a classification framework for sustainability practices and approaches. To fill this gap, current study aims to classify strategies in 3DCP to enhance environmental sustainability and offer recommendations for further research. To achieve this goal, first, a bibliometric analysis, a computer-aided statistical method for reviewing the literature, is employed. This analysis will explore, measure, and map existing research to identify current trends and the state-of-the-art in the field. Subsequently, a thematic analysis of the keywords categorises prior sustainability strategies. Finally, benchmarking concrete technology offers some recommendations for mitigating sustainability concerns and assessing the benefits of applied strategies. The results show that research in the realm of sustainable 3DCP began in 2017 and has a significant growth rate of 1.5 times per year. Besides, strategies to improve the sustainability performance of 3DCP pursue four main targets: reducing carbon footprint and raw material consumption, increasing durability characteristics, and enhancing thermal performance.

Notable applications include enhanced air quality predictions, water quality assessments, climate impact forecasting, and automated wildlife monitoring using AI-driven image recognition. Challenges such as the “black-box” nature of AI models, the need for high-quality data in resource-constrained regions, and the complexity of real-time disaster management are also addressed. The study highlights ongoing efforts to develop explainable AI (XAI) models, which aim to improve model transparency and trust in critical environmental applications. Future research directions emphasize improving data quality and availability, fostering interdisciplinary collaborations across environmental and computer sciences, and addressing ethical considerations in AI-driven environmental management. These findings underscore the transformative potential of AI and ML technologies for sustainable environmental management, offering valuable insights for researchers and policymakers in addressing global environmental challenges.

This study addresses environmental concerns related to construction and demolition waste (CDW), which constitutes 35–40% of global waste. It explores the potential use of recycled fine aggregates (RFA) from concrete demolition waste as a sustainable alternative to natural fine aggregates in 3D printed mortar (3DPM). By conducting a systematic literature review (SLR) and utilizing VOSviewer for bibliometric analysis, the research assesses the mechanical properties, flowability, extrudability, and buildability of RFAs in 3DPM. The analysis also highlights key trends in keywords and research distribution across different countries. The findings reveal that while RFAs in 3DPM slightly reduce compressive and flexural strengths compared to natural aggregates, they significantly contribute to environmental sustainability by reducing landfill waste and conserving natural resources. The study underscores the importance of further research to optimize RFA-based mixtures for wider application in 3D printing technologies.

The quick, easy, cheap, effective, rugged, and safe (QuEChERS) method is a sample preparation technique originally used in analytical chemistry for the extraction and purification of pesticide residues in food. In recent years, the approach has evolved beyond its original scope to include environmentally relevant analytes other than pesticides and matrices other than food. The main objective of this paper is to provide a chronological overview of bibliometrics and to present the development of QuEChERS applications from publishing the method in 2003 to present using the tools BibExcel, VOSviewer, and Bibliometrix. A bibliometric analysis was carried out using the Science Citation Index Expanded database (WoS©) to analyze the scientific literature published in the field over the last 20 years and to identify limitations and future research directions. Yearly production of scientific publications increased steadily, and Price’s index (50.3%) showed that QuEChERS method research is still relevant after 20 years. China and the USA were the most productive and collaborative countries in the field, and all the documents (4789) were published in 56 different subject categories of WoS©, which implies that QuEChERS method research is multidisciplinary in nature. This is the first bibliometric review of the QuEChERS method, where trend topics in the keywords show the evolution of the QuEChERS method into other fields complementary to pesticide analysis as a risk in food safety.

Numerous studies have been conducted to investigate the impact of microplastics on soil eco-system, yet little attention has been given to the specific effects of mulch microplastics and the leaching of plastic additives from mulch films. This review inspects the propensity of commonly used plastic additives in mulch films, such as Di(2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and benzophenones (BPs), to migrate into soils and pose potential risks to soil biota. Further, we highlight the degradation of non-biodegradable plastic mulch films over time, which leads to an increase in the release of plastic additives and microplastics into agricultural soils. DEHP has been detected in high concentrations for example 25.2 mg/kg in agricultural soils, indicating a potential risk of uptake, translocation and accumulation in plants, ultimately altering soil physicochemical properties and affecting soil microflora and invertebrates. The review also explores how exposure to ultraviolet (UV) radiation and microbial activities accelerates the weathering of mulch films. Moreover, the resultant plastic additives and mulch microplastics can lead to genotoxicity and growth inhibition in earthworms (Eisenia fetida) and negatively impact the soil microbiome. Despite the significant implications, there has been a lack of comprehensive reviews comparing the effects of non-biodegradable mulch film additives on agricultural soil flora and fauna. Therefore, this review addresses the knowledge gaps providing a bibliometric analysis and eco-toxicological evaluation, discussing the challenges and future perspectives regarding mulch plastic additives and microplastics, thus offering a comprehensive understanding of their impact.

Sustainability issues constitute a distinct subdiscipline of librarianship and information science, with its own areas of study, methods, and areas of application. Despite being nearly 30 years old, there are still divergent opinions on its current phase of development and its links to other scientific disciplines. The authors aim to clarify and summarize the ongoing discussion through citation analysis, shedding light on the lifecycle of research papers in sustainability-oriented library and information science, the current research subjects of focus, the influence of subdomains within the discipline on other scientific areas, and the overall quantitative and qualitative landscape of the discipline. A detailed elucidation of the inquiry’s results is intended to outline the discipline’s cognitive structure and its impact on sustainability science. The lifecycle of disciplinary papers indicates the dynamic development of the field. Sustainability-oriented library and information science is well-established, and its research focus has already been consolidated. The optimal citation window for measuring the impact strength in this discipline is a period of 3 to 4 years. “Culture” and “Education” have been identified as the most forward-looking subdisciplines, whereas “Buildings” and “Collections” exhibit less dynamic growth. The social sustainability pillar is the dominant one, while the environmental pillar is slightly less prominent. The economic pillar is the least represented. Although the majority of information exchange occurs within the discipline, it maintains strong and numerous links with several other fields, including both technical and social sciences, as well as the humanities.

La fragmentación del hábitat y la urbanización están teniendo un impacto dramático en las comunidades de insectos.

This study offers numerous recommendations for further research on ESG controversies to advance the research stream.

Biodiversity conservation and ecosystem management are imperative for sustaining life on Earth. Despite the growing recognition of its importance outside the field of environmental sciences, biodiversity has been polemically criticized as a fad, arguing that it has become a passing trend in sustainable finance. To foster a comprehensive understanding, we provide a bibliometric analysis of 334 articles in accounting, economics, and finance (AEF) journals retrieved from the Web of Science database. We conduct science mapping and a co-citation analysis to portrait the scientific landscape and research foci. Consistent with previous studies, we find that mainstream AEF journals are largely silent on biodiversity. In addition, research from Asia is severely underrepresented.

This study highlights the interdisciplinary and collaborative nature of machine learning research in biofuels and biodiesel, driven by substantial contributions from key funding bodies and researchers worldwide.

Seawater desalination (SWD) can partially mitigate the increasing freshwater needs globally. Although, SWD is multifaceted and involves processes with environmental and economic challenges, research is often analyzed through Literature Reviews (LRs) in specific contexts that may miss general trends. Bibliometric Analyzes (BAs), however, provide researchers with an overview through Co-occurrence Networks (CNs), Strategic Diagrams (SDs), Thematic Subnetworks (TSs), and Thematic Evolution Diagrams (TEDs). Nevertheless, their use in SWD research has been limited, with minimal attention given to them. Thus, we created a bibliometric dataset, compared it with other BAs, and developed CNs, SDs, TSs, and a TED for SWD. Furthermore, key term searches (Energy, Solar, Reverse Osmosis, Modeling and Optimization, Membrane Distillation, Environmental, Economics, Fouling, Nanofiltration, and Ultrafiltration) and their literature are discussed. Geographical analysis shows China and the US lead SWD research, shifting from process design to membrane fabrication and solar energy. Furthermore, RO remains the leading technique despite high energy demands. Solar desalination shows promise but faces cost and scalability challenges. Environmental and economic concerns are discussed, as well as emerging solutions regarding, solar desalination, blue energy, “blue carbon”, and zero liquid discharge. Research gaps include fouling effects and pretreatment incorporation in optimizations are also highlighted.

Electronic waste (E-waste) has been extensively investigated by researchers throughout the globe, however specific research trends in North America (NA) are yet unknown. This study attempts to present an up-to-date bibliometric view of the e-waste studies, and to identify the research sub-fields and networks. A total of 370 documents were retrieved from the WoS database (from 2005 to 2023). E-waste research topic that originated from NA, as well as its relative growth rate, collaborative measures, institutional productivity, and the popular journals were evaluated in this bibliometric analysis. The study showed that research productivity increased noticeably in the last decade. The USA has the most e-waste publications (72.70%), followed by Canada (22.70%) and Mexico (9.19%). The topic with the highest percentage of papers (209, or 56.49%) was environmental science. Resources Conservation and Recycling was the most active journal on e-waste research. The University of California, USA (8.64%) played an active role in the publication. Author’s keywords can be generally grouped into four clusters. Network analysis results suggest that collaborative activities by leading universities will likely boost the number of studies. A diversified and strong collaborative research network may be a key driver for e-waste research output, but not necessarily research impact. It is recommended that policy makers and funding agencies create collaborative funding programs specifically for e-waste research.

Green Building (GB) and Circular Building (CB) are key concepts for advancing a sustainable built environment (SBE). Due to the growing emphasis on sustainability, integrating these two concepts into building projects has become a common goal for the stakeholders involved. However, there is a lack of holistic exploration of the promotion strategies of various stakeholders for both concepts. Herein, a bibliometric-systematic review of the studies on promotion strategies for the GB and CB concepts that were published between 2018 and 2023 and indexed in Scopus is presented. The results reveal a spectrum of strategies employed by three stakeholder groups—public entities, professionals, and clients. A systemic perspective is provided for categorizing these strategies into eight distinct dimensions: Education, Policy, Technological promotion, Knowledge, Practice, Management, Market demand, and Investment. Additionally, the study highlights the dual forces of driving forces and pressures generated by different strategies, depending on the stakeholder roles. By extending these findings, this review maps a strategic stakeholder network, thus providing a visual depiction of stakeholder relationships and the impact of their promotion strategies. The novelty of this study lies in its comprehensive overview of stakeholder roles and their promotion strategies for GB and CB, surpassing mere discussion of individual roles or concepts. This study contributes valuable insights for stakeholders seeking effective promotion strategies to implement GB and CB concepts, thereby advancing the built environment toward greater sustainability.

Phytoremediation is recognized as an environmentally friendly technique. However, the low biomass production, high time consumption, and exposure to combined toxic stress from contaminated media weaken the potential of phytoremediation. As a class of plant-beneficial microorganisms, arbuscular mycorrhizal fungi (AMF) can promote plant nutrient uptake, improve plant habitats, and regulate abiotic stresses, and the utilization of AMF to enhance phytoremediation is considered to be an effective way to enhance the remediation efficiency. In this paper, we searched 520 papers published during the period 2000–2023 on the topic of AMF-assisted phytoremediation from the Web of Science core collection database. We analyzed the author co-authorship, country, and keyword co-occurrence clustering by VOSviewer. We summarized the advances in research and proposed prospective studies on AMF-assisted phytoremediation. The bibliometric analyses showed that heavy metal, soil, stress tolerance, and growth promotion were the research hotspots. AMF–plant symbiosis has been used in water and soil in different scenarios for the remediation of heavy metal pollution and organic pollution, among others. The potential mechanisms of pollutant removal in which AMF are directly involved through hyphal exudate binding and stabilization, accumulation in their structures, and nutrient exchange with the host plant are highlighted. In addition, the tolerance strategies of AMF through influencing the subcellular distribution of contaminants as well as chemical form shifts, activation of plant defenses, and induction of differential gene expression in plants are presented. We proposed that future research should screen anaerobic-tolerant AMF strains, examine bacterial interactions with AMF, and utilize AMF for combined pollutant removal to accelerate practical applications.

More than two-thirds of the Earth’s surface is covered by oceans and yet only a small portion of these oceans has been directly explored in detail, highlighting the need for powerful tools like remote sensing (RS) technology to bridge this gap. International frameworks, the 2030 Agenda for Sustainable Development, and Ocean Decade point out the significance of marine areas for achieving sustainable growth. This study conducts a bibliometric analysis of RS over marine areas for sustainable development to identify key contributors, collaboration networks, and evolving research themes from the beginning of the 21st century until last year. Using the Web of Science Core Collection database, 499 relevant articles published between 2000 and 2023 were identified. The bibliometric analysis showed a significant increase in scientific productivity related to the field. On an international level, China emerges as the most productive country, but international collaboration has played a crucial role, with 36.87% of articles resulting from international co-authorship, pointing to the global nature of research in this field. RS technology has continuously evolved from airborne sensors to the augmentation of Earth Observation missions. Our findings reveal a shift towards automated analysis and processing of RS data using machine learning techniques to integrate large datasets and develop robust scientific solutions.

Landslide is a typical geological disaster distributed in most countries worldwide. Due to long-term natural weathering and human engineering disturbances, the instability of landslides is prone to occur. Once monitoring and disposal methods are implemented inappropriately, they can lead to landslide hazards, seriously threatening the safety of people’s lives and property. For a long time, extensive research on landslide monitoring has been conducted from various countries, providing crucial technical support for reducing the incidence and severity of landslide hazards. However, considering the complex geological conditions of actual landslides and the direct impact of internal and external factors such as rainfall, storms, and earthquakes, the early warning accuracy of landslide hazards is still relatively low. Therefore, based on advanced research achievements, it is significant to carry out research on the current status and development trends of landslide monitoring technology. Based on the Web of Science core database, this study quantitatively analyzes the advanced research achievements in global landslide monitoring in the past decade using bibliometric analysis. A systematic analysis of landslide monitoring technology development is conducted according to each study’s publication time, keywords, and countries. On this basis, a multi-dimensional monitoring system for landslides was proposed, which utilizes the complementary advantages of multi-dimensional monitoring technology to achieve all-round, high-precision, and real-time monitoring of landslides. Finally, taking the Xinpu landslide in the Three Gorges Region of China as an example, a multi-source and multi-field-monitoring experiment was conducted. The application of landslide multi-field-monitoring technology provides an essential reference for monitoring, early warning, as well as the scientific prevention and control of landslide hazard.

Climate change presents one of the most significant challenges facing the world in the 21st century. In 2019, the UK became the first major economy to pass laws to end its contribution to the world’s greenhouse gas emissions; parliament passed legislation requiring the UK government to achieve its carbon neutrality commitment by 2050. This will require all industries, including the housing sector, which currently contributes around 14% of the UK’s greenhouse gas emissions, to reduce their carbon emission contribution. One of the ways in which the housing sector plans to accomplish this is through delivering new zero carbon ready homes by 2050, at the latest. This study makes an innovative contribution to advancing the field of carbon neutral construction through its identification of the barriers to the UK in regards to their ability to deliver zero carbon homes (ZCH) and the provision of potential recommendations to overcome these barriers. To achieve this, a mixed-review method is used, combining a qualitative systematic analysis and a quantitative bibliometric approach. Several key barriers were identified and assigned to following key themes: legislative, socio-cultural, economic, financial, skills and knowledge, technical, industrial, environmental, and procurement factors. Legislative obstacles were found to be a primary barrier due to a lack of certainty, clarity, and clear definitions, as well as the removal and excess of government policies. Significantly, the findings reveal the under-researched impact of recent disruptive events, such as the COVID-19 pandemic, Brexit, and economic factors in the UK, opening up novel avenues for exploring their implications. Overall, this study advances industry understanding and highlights innovative directions necessary to propel the sector towards realizing the UK’s legally-binding 2050 net zero target through the development of zero carbon ready homes.

Pollutants in water bodies pose a serious threat to both the aquatic ecosystem and human health. Ion exchange is used as a chemical process to remove unwanted dissolved ions from water and wastewater. It is widely accepted in developing countries. This analysis provides a bibliometric examination to consider the status and trends of advanced ion exchange worldwide. This study was conducted using the Dimensions website to identify and collect the most important research papers. The retrieved manuscripts were organized through Microsoft Excel and then VOS viewer was used to analyze the data by reviewing previous studies related to ion exchange as a contaminant removal treatment. To create maps and find out which countries, universities, and journals have published research articles on topics related to ion exchange, as well as authors who have studied the topic of ion exchange and their research, cooperation. To benefit from these studies and learn the importance of ion exchange as a treatment for removing pollutants. The electro neutrality of the ion exchange (IOEX) process must always be maintained because it is a stoichiometric process. Search results for IOEX were exported from Dimensions to a CSV file, both coexistence, cooperation with affiliate countries and consortia were implemented on the full search results. Ion exchange treatment has proven effective in treating industrial wastewater and domestic wastewater. Professionals and practitioners in the field are provided with important information through this examination of ion exchange research. The analysts learned about leading academic and research institutions, the state of the exploration field, and the most controversial issues surrounding advanced ion exchange. In addition, this lesson will provide the opportunity to learn basic facts that will develop the extent of ion exchange knowledge. The bibliometric survey method can also be used to visualize the trend of research and study in various fields.

Wildfire prediction plays a vital role in the management and conservation of forest ecosystems. By providing detailed risk assessments, it contributes to the reduction of fire frequency and severity, safeguards forest resources, supports ecological stability, and ensures human safety. This study systematically reviews wildfire prediction literature from 2003 to 2023, emphasizing research trends and collaborative trends. Our findings reveal a significant increase in research activity between 2019 and 2023, primarily driven by the United States Forest Service and the Chinese Academy of Sciences. The majority of this research was published in prominent journals such as the International Journal of Wildland Fire, Forest Ecology and Management, Remote Sensing, and Forests. These publications predominantly originate from Europe, the United States, and China. Since 2020, there has been substantial growth in the application of machine learning techniques in predicting forest fires, particularly in estimating fire occurrence probabilities, simulating fire spread, and projecting post-fire environmental impacts. Advanced algorithms, including deep learning and ensemble learning, have shown superior accuracy, suggesting promising directions for future research. Additionally, the integration of machine learning with cellular automata has markedly improved the simulation of fire behavior, enhancing both efficiency and precision. The profound impact of climate change on wildfire prediction also necessitates the inclusion of extensive climate data in predictive models. Beyond conventional studies focusing on fire behavior and occurrence probabilities, forecasting the environmental and ecological consequences of fires has become integral to forest fire management and vital for formulating more effective wildfire strategies. The study concludes that significant regional disparities in knowledge exist, underscoring the need for improved research capabilities in underrepresented areas. Moreover, there is an urgent requirement to enhance the application of artificial intelligence algorithms, such as machine learning, deep learning, and ensemble learning, and to intensify efforts in identifying and leveraging various wildfire drivers to refine prediction accuracy. The insights generated from this field will profoundly augment our understanding of wildfire prediction, assisting policymakers and practitioners in managing forest resources more sustainably and averting future wildfire calamities.

Assisted Natural Regeneration (ANR) is a set of restoration strategies and interventions primarily based on natural regeneration, aimed at accelerating succession and providing multiple benefits in degraded ecosystems and landscapes. These strategies have the potential to significantly contribute to global Forest and Landscape Restoration efforts. However, ANR faces challenges due to limited recognition, support, and formal integration into relevant sectors and restoration policies, particularly in tropical regions. The dearth of evidence-based syntheses further compounds these challenges. To address this gap, a bibliometric analysis of selected scientific publications on ANR (n = 208) from 1987 to 2023 was conducted, using Web of Science and Google Scholar databases. A systematic review was undertaken, using a subset of original research articles (n = 44), to synthesize published data on interventions, contexts, costs, and benefits of ANR and to identify major knowledge gaps. Analysis of bibliometric metadata revealed an increasing annual output of ANR publications in over 80 journals, encompassing various document types and authors from over 40 countries. Despite ANR’s formal emergence in the Philippines, Brazil has taken the lead in both its research and implementation, and international collaboration in ANR research has grown. While ANR research focused mostly on ecosystem services and ecological outcomes, social aspects have been poorly studied. Diverse ANR interventions align not only with ecological restoration but also with integrated land management, biodiversity conservation, forest and landscape restoration, and forest management. The cost-effectiveness of ANR implementation, especially in restoration for carbon storage, exhibited considerable variability when compared to active tree planting, and varied with intervention types, time, land use history, and long-term costs. This synthesis provides critical insights and evidence to enhance the effective integration of ANR into restoration and reforestation programs and policies.

The bibliometric method was used in this study to analyze current advances in the anaerobic digestion (AD) of cellulose waste. The result shows that the number of articles increased rapidly after 2010, suggesting a growing interest in this field. The USA and China were the top two countries with the highest number of published articles. AD of cellulose waste is being actively explored in many countries, and partnerships between countries are being actively formed. The top three subject categories were Environmental Sciences & Ecology, Engineering, Energy & Fuels. The most widely published and influential journals were Bioresource Technology, Water Science and Technology, and Waste Management. The co-occurrence and trend analysis of author keywords indicates that current research is primarily focused on pretreatment and co-digestion. Microbial community analysis plays a crucial role in elucidating the mechanisms, and life cycle analysis (LCA) could evaluate the impact on the environment at different stages. Microbial community analysis and LCA will be the hotspots in the future. To some extent, this study helps to understand the current global status and trends of the related research.
