This research examines the complex relationship between climate change, rapid population growth, and building stock expansion in Egypt, as well as their combined impact on energy demand and urban sustainability, to address the rapidly increasing electricity demand. This study uses a mixed-methods approach, including quantitative analysis to examine climatic data (1970–2100), demographic trends, and building energy consumption patterns, quantifying their synergistic effects; a qualitative evaluation of policy frameworks and urban planning strategies; and building energy performance simulation using Design Builder to utilize climate-responsive design techniques for energy reduction. Finally, this study proposes energy-efficient design guidance. The research findings reveal that Egypt’s unique hot–arid climate, projected to warm by 4 °C by 2100, combined with a population set to reach 160 million by 2050, has driven the near-doubling of building stock since 1986, with residential buildings accounting for 70–83% of structures and 60% of national electricity use. The research results highlight the importance of implementing climate-responsive design strategies (optimized building-envelope thermal insulation and energy-efficient HVAC systems) in Egypt’s built environment to reduce electricity consumption by up to 40%, thereby aligning urban growth with sustainability objectives. These insights are scalable to other arid, rapidly urbanizing regions globally.

This paper focuses on the coordinated development and barrier factors of green logistics (GL) and regional economy (RE) in the Yellow River Basin (YRB). Based on data from 2014 to 2023, it constructs an index system covering the development foundation, benefits, potential and sustainability of GL, as well as regional economic structure, scale and potential. Using methods such as the entropy method, coupling coordination degree (CCD) model, kernel density estimation, Moran’s index and Obstacle degree model, it reveals that the average comprehensive CCD improved from 0.38 to 0.65 over the decade, but with significant regional differences. Eastern provinces like Shandong and Henan are ahead, while central and western provinces lag. The coupling coordination degree shows an overall upward trend, moving toward coordinated development with an expanding spatial pattern from east to west and narrowing regional gaps. Global Moran’s index (ranging from 0.356 to 0.524) indicates a spatial positive correlation, and local spatial autocorrelation analysis shows coexistence of high–high and low–low clusters. For Obstacle factors, GL is primarily constrained by low labor productivity (indicator B3, accounting for 23.1% to 44.7% of the total obstacle degree) and shortcomings in logistics industry benefits and scale, while RE is hindered by lagging economic structure optimization, weak foreign trade, and insufficient economic scale and vitality. This study provides a theoretical basis and decision-making reference for the high-quality coordinated development of GL and RE in the YRB, promoting regional coordination and sustainable development.

Local governments increasingly combine power purchase agreements (PPAs) with local retail power producers and suppliers (RPPSs) to pursue decarbonization and regional revitalization. However, there is limited municipal-scale evidence on how contractual design translates into regional multiplier and employment outcomes under structural uncertainty. Using a 38-sector municipal input–output table (2015) for Fukuchiyama City, Kyoto, Japan, we conduct scenario-based simulations to quantify the output and employment multipliers of on-site and off-site solar photovoltaic PPAs. We compare Type I multipliers (household exogenous) and Type II multipliers (household endogenous) across nine scenarios that combine three PPA arrangements—off-site sales to the local RPPS [A], off-site sales to a major utility [B], and on-site self-consumption [C]—with three interregional leakage scenarios (1)–(3). A systematic sensitivity analysis (±10–20% perturbation of structural coefficients) was implemented to provide results as conditional ranges rather than point estimates. Under baseline leakage (3), off-site PPAs sold to the local RPPS [A3] yield the largest short-term total effects (1.24 million USD/year). Crucially, the error bars confirm that the policy ranking of A > B > C remains robustly invariant across all leakage conditions. Endogenizing households increases total effects by approximately 22.9% without changing this ranking, with induced effects concentrated in consumption-related services. In contrast, on-site PPAs [C] yield significantly larger long-term cumulative multipliers through stable expenditure savings from avoided electricity purchases. These results provide a transferable evaluation protocol and identify policy levers—off-taker localization, local supply chain thickening, and localized O&M—that jointly determine whether PPAs deliver broad-based regional economic benefits.

Land use/land cover (LULC) change significantly influences a range of environmental and socio-economic issues, including climate change, deforestation, biodiversity loss, soil degradation, ecosystem services, and food security, at local, regional, and global levels. In the northwestern Himalayan region, particularly in Rajouri district of Jammu and Kashmir (J&K), LULC change has profound environmental and socio-economic implications. Understanding the temporal and spatial dimensions of LULC change is crucial for assessing the impact of human activities on the region’s environment. The present study aimed to analyze LULC change in Rajouri district of J&K, India over a 30-year period from 1990 to 2020 and to project future LULC dynamics for the next 30 years up to 2050. Landsat imagery with a supervised classification technique was used for classification and generation of LULC maps. Moreover, CA Markov model was used to predict the future LULC status of the area. The model validation exhibited strong performance, with Kappa statistics exceeding 0.90, indicating a high level of reliability in the projections. The results indicate considerable changes in different land use classes from 1990 to 2020. Over the 30-year period, dense forest showed the maximum reduction of about −20.69 Km2, followed by open forest (−15.87 Km2) and grassland (−13.75 Km2). Wasteland showed the maximum increase of about +28.24 Km2, followed by built-up (+17.90 Km2) and cropland (+12.50 Km2). The cumulative impact of deforestation from 1990 to 2020 amounts to approximately 43.17 Km2, while afforestation efforts only managed to reclaim 6.61 Km2 of land. The future prediction using the CA Markov model suggests further changes in LULC patterns, with built-up, cropland, and wasteland projected to increase exponentially by 2050, accompanied by sharp declines in forests. Therefore, policymakers should prioritize sustainable land management and forest conservation strategies to mitigate the potential negative impacts of LULC changes on the environment, ensuring balanced and sustainable development.

This paper employs a top-down methodological approach to identify the most relevant contributions in the literature on the impact of European Cohesion Policy and European Structural and Investment Funds (ESIFs) on regional development. After a broad-spectrum bibliometric review, identifying the overall structure of research in this field, we systematically narrow its focus to quantitative studies and, ultimately, to econometric analyses of ESIF effectiveness. The results indicate that empirical research on ESIFs has grown in complexity, with increasing reliance on advanced econometric techniques such as spatial econometrics, difference-in-differences, and regression discontinuity designs. While a large portion of the literature finds positive effects on economic growth, employment, and regional convergence, these effects are frequently conditional on governance quality, institutional frameworks, and regional characteristics. In contrast, some studies report insignificant or even negative impacts, highlighting inefficiencies in fund allocation and policy implementation. The findings emphasize the necessity for context-specific policy adaptations, ensuring that ESIFs continue to support the evolving needs of regional economies in the European Union.

Quality of life, as an essential component of sustainable development, is particularly relevant in transnational contexts characterized by deep inequalities in human development, equity, and social well-being. The objective of this paper is to analyze the temporal and spatial changes in transnational patterns of quality of life observed between 2018 and 2025, taking into account levels of human development. To this end, multivariate statistical techniques were applied: partial triadic analysis, which allows the identification of both the common structure of the data and the temporal evolution of the indicators, together with the HJ-Biplot and cluster analysis, which provide a multidimensional and interpretable visualization of country profiles. The results reveal consistent configurations of quality of life, largely aligned with levels of human development, and highlight persistent inequalities in environmental quality, economic accessibility, and objective well-being. These findings are relevant for the formulation of policies aimed at enhancing population well-being, particularly in countries facing structural constraints despite their high levels of development. The contribution of this research lies in its three-dimensional, dynamic, and reproducible approach, which makes it possible to identify regional contrasts that are not visible through traditional methods based on unidimensional indicators or cross-sectional analyses.

Understanding how green spaces foster sense of place is critical for sustainable urban planning and human well-being, yet no comprehensive synthesis has integrated findings across the fragmented literature spanning multiple disciplines. This systematic review analyzed 497 empirical studies examining green space-place attachment relationships, following PRISMA guidelines across three major databases through June 2025. Beyond documenting the field’s rapid growth—from 10 annual publications pre-2010 to over 50 by 2021—this review reveals critical patterns and gaps with implications for theory and practice. While the term ‘place attachment’ was most frequently used (45% of studies), the field employs diverse terminology often without clear definitional boundaries. Only 18% comprehensively addressed the Person-Process-Place tripartite model, with process dimensions particularly neglected. This theoretical incompleteness limits the understanding of how attachments form and evolve. Geographic analysis exposed severe disparities: 78% of studies originated from high-income countries, with Africa (2.4%) and South America (3.6%) critically underrepresented, raising questions about the applicability of current theories beyond Western contexts. Urban settings dominated (49.5%), potentially overlooking rural and indigenous perspectives essential for comprehensive understanding. Methodologically, studies demonstrated sophistication through strategic deployment of quantitative (60%), qualitative (15%), and mixed methods (25%). Key thematic areas, residence duration, restorative benefits, and pro-environmental behaviors, showed promise, yet environmental justice remained underexplored despite its critical importance. This synthesis advances the field by identifying specific pathways for progress: expanding geographic representation to develop culturally inclusive theories, employing longitudinal designs to capture attachment formation processes, developing validated cross-cultural measures, and centering environmental justice in green space planning. These findings provide essential guidance for creating equitable green spaces that foster meaningful human-nature connections across diverse global contexts.

Due to the mobility of many pest species, effective integrated pest management (IPM) requires spatial coordination of management actions. This paper examines how the consideration of spatial dynamics, spatially coordinated collaboration, and supportive policy instruments improve pest management in agricultural landscapes. We consider empirical studies that explore the effects of spatial structure and processes on pest dynamics; conceptual frameworks that address larger spatial scales, such as Area-Wide Pest Management (AWPM); and policy instruments such as Payments for Ecosystem Services (PES) that have an impact on the land use in agricultural landscapes. The aim is to highlight how these three pillars of effective pest management are interrelated. Challenges and approaches for the establishment of spatial collaboration in agricultural pest management are identified and avenues for future research are presented.

This study develops an updated national Social Accounting Matrix (SAM) for Greece, based on the 2020 Input–Output Table that captures post-crisis structural and macroeconomic transformations, implemented in Python 3, hence producing a reusable, modular code. This methodological approach facilitates multiplier-based policy analysis of how shocks propagate through the Greek economy, and therefore, this study contributes to the literature by addressing the gap in multiplier analysis for this setting. Output, value-added, and income multipliers were estimated using the Moore–Penrose pseudo-inverse via Singular Value Decomposition (SVD). Findings highlighted the substantial role of government transfers in supporting household and firm incomes, largely due to COVID-19 relief measures. This analysis showed that production expansion in energy, construction, and wholesale and retail trade can stimulate broad economic activity, while service-related sectors play a critical role in income generation and equity considerations. At the same time, firms in trade, hospitality, and real estate were heavily affected by the pandemic shock. The findings of this study provide a benchmark for understanding Greece’s economic structure at a critical moment in time (the COVID-19 pandemic).

Over the centuries, human interaction with natural resources has allowed us to build knowledge that has given rise to cultures and regions around the world. In Mexico, particularly in the Yucatán Peninsula region, the traditional Mayan house (TMH) represents a symbol of identity and ancestral knowledge of the Mayan culture and a way of life for the inhabitants of rural communities. However, there is little information on the flora used as raw materials for the construction of the TMH; considering that its structure is being modified with modern materials. The objective of this study has been to identify the different plant species used as raw materials for the construction of TMHs in different Mayan communities in northern Campeche, Mexico. A total of 27 surveys were conducted in seven communities using the snowball method, using non-probability convenience sampling. In total, 100% of the respondents were male, between 18 and 86 years old, of whom 73% learned about the construction of the TMH through knowledge transferred by their parents, while the remaining 27% learned from their grandparents. For the construction of the TMH, a total of 18 plant species were recorded; 100% of the respondents mentioned that they use Sabal yapa “Xa’an guano” (in Mayan) for the construction of the roof. Another 18% mentioned the use of grass (Spartina spartinae). It can be therefore concluded that there is a hybridization of the TMH, since the roofs are replaced with zinc sheets due to the low cost of modern materials and the low availability of Sabal yapa in some areas of northern Campeche.

Sandstone quarrying in Lekokoaneng contributes to both local and national economic development, yet it raises concerns about environmental degradation and community livelihoods. Using a mixed-methods design framed by the Sustainable Livelihood Framework (SLF) and the Sustainable Development Theory (SDT), 203 households were surveyed across five buffer zones (0–1000 m) around the formal quarry site in Lekokoaneng, Berea District, Lesotho. Quantitative data were analysed descriptively, while qualitative responses underwent thematic analysis and were transformed into quantifiable categories. Quarrying generated employment and small-business opportunities concentrated within 0–600 m of the site, alongside elevated reports of dust, soil degradation and water contamination that undermined agriculture and health. Households nearest the quarry reported the highest income benefits (e.g., 35% via employment) but also the greatest environmental burdens. Households furthest away reported fewer risks but also limited economic gain. Thematic analysis yielded four domains: Socio-Economic Empowerment, Livelihood Vulnerability, Health and Safety Risks, and Environmental Degradation and Control. Integrating SLF and SDT shows quarrying as a double-edged livelihood system with short-term financial gains that coincide with erosion of natural, human and social capitals. Targeted environmental safeguards, labour formalisation and community-inclusive governance are essential to realign quarrying with resilience and sustainability goals.

Against the backdrop of the accelerated integration of culture and tourism in China, red cultural tourism, as an important component of China’s cultural tourism system, urgently requires a systematic assessment of its development status and synergistic impact mechanisms. This study takes the Long March tourism resources in Yunnan as the research object and constructs a comprehensive evaluation system integrating social influence and ecological carrying capacity. By applying GIS spatial analysis, as well as K-means and XGBoost machine learning models, the development level of red cultural tourism in Yunnan is quantitatively assessed. Furthermore, the interpretable SHAP model is employed to identify the contribution of each evaluation indicator and to analyze the relationships among development levels under three different indicator models. The results reveal that (1) the development level of red cultural tourism in Yunnan generally exhibits a spatial pattern of being lower in the northwest and higher in the southeast; (2) transportation accessibility (TA), average annual precipitation (AAP), and average annual temperature (AAT) are the dominant indicators influencing the development level; (3) there are significant disparities in development levels among cities, indicating that future development needs to comprehensively consider both the social influence and ecological carrying capacity of red cultural tourism resources and adhere to a “social–ecological” synergistic development mechanism. This study not only uncovers the synergistic impacts of social and ecological dimensions on the development of red cultural tourism in Yunnan but also provides theoretical and data support for the optimization and sustainable development of Yunnan’s red cultural tourism resources.

The regionalization of input–output tables enables a granular understanding of economic systems, allowing for interregional and interindustry analysis for goods and services in a local economy. This paper details the construction of an intermunicipal IO matrix for the state of Rio Grande do Sul (Brazil), a region marked by both economic diversification and significant territorial disparities. Using the 16-sector state IO matrix (base year 2019) provided by the state-level treasury (SEFAZ-RS) as a starting point, we adapt the Interregional Input–Output Adjustment System (IIOAS), integrating gravity-based trade modelling and RAS balancing, to produce a disaggregated structure for 497 municipalities. The regionalization follows three main steps: (i) generation of an initial matrix assuming proportional municipal shares in sectoral supply and demand; (ii) iterative RAS-based adjustments to align with municipal and state-level constraints; and (iii) incorporation of complementary municipal data—including employment, GDP, household consumption, and exports—to refine final demand and value-added allocations. The results demonstrate the feasibility of deriving spatially intermunicipal IO structures from limited data. The results show that, while industrial and service activities are concentrated around the Porto Alegre metropolitan area, rural subregions remain specialized in low value-added primary sectors.

The European Union (EU) has positioned itself as a global leader in digital regulation, with landmark frameworks such as the Digital Services Act (DSA), the Digital Markets Act (DMA), and relevant AI Act. These initiatives reflect the EU’s ambition to balance technological innovation with consumer protection, market fairness, and digital sovereignty. Yet, a growing body of research suggests that the EU may be lagging its global competitors—namely the United States and China—when it comes to scaling high-growth digital enterprises and attracting investment in frontier technologies. This study investigates the paradox of regulation versus innovation in the EU by comparing key performance indicators such as R&D investment, venture capital availability, and digital innovation output with those of the U.S. and China. Drawing on datasets from WIPO, the OECD, IMF, and the World Bank, the paper incorporates both cross-sectional and longitudinal analysis to assess the EU’s digital trajectory. Findings suggest that while the EU excels in institutional frameworks and research output, structural barriers—such as regulatory fragmentation and underdeveloped capital markets—limit its global competitiveness. The article concludes by discussing policy implications and the need for adaptive governance to maintain Europe’s digital leadership.

Sustainable tourism development has emerged as a strategic priority across ASEAN countries, yet the role of green innovation and environmentally responsible investment in shaping tourism outcomes remains underexplored. Existing studies often overlook the spatial interdependencies that characterize regional integration and cross-border environmental dynamics. This study investigates how green patents and green foreign direct investment (FDI) influence sustainable tourism development, both within and across ASEAN nations. Drawing on endogenous growth theory, ecological modernization, and FDI spillover frameworks, the analysis employs a Spatial Durbin Model (SDM) using panel data from 2000 to 2023. The findings reveal that green innovation and green FDI significantly enhance tourism development, with notable spatial spillover effects that benefit neighboring countries. These effects are most pronounced in leading ASEAN economies, where institutional capacity and absorptive readiness amplify the impact of green practices. The relationship is further shaped by economic growth, human capital, and political stability, while environmental degradation and inflation pose constraints. The study underscores the nonlinear and regionally heterogeneous nature of green tourism development, offering policy insights for fostering inclusive, resilient, and environmentally sustainable tourism strategies across ASEAN.

Since 1980, a land use type known as parcelas de agrado has developed in Chile, generating a series of social, economic, and environmental impacts. In recent years, its use has increased further and has become a subject of public debate. To address this, it is necessary to have evidence that documents its evolution. Within this context, the aim of the article is to analyze the state of the literature on parcelas de agrado in Chile. The method is based on three stages: the application of the PRISMA model for the identification and selection of documents, the establishment of areas and categories for quantitative analysis, and content analysis based on five dimensions. The results show a diversity of types of studies conducted in different years, territories, and scales in Chile, with a greater concentration of scientific articles and studies in areas of the central macrozone of Chile. The discussion highlights the diversity and proliferation of studies, facilitating elements and the spread of parcelas de agrado, the consequences on the territory, as well as the contribution of spatial planning. It is concluded that parcelas de agrado in Chile require greater attention from the State in relation to the territorial planning of rural, peri-urban, and suburban areas.

Urban community gardens (UCGs) have been expanding globally. Initially created to provide fresh, organic produce for low-income populations, UCGs have evolved into models of sustainable agriculture with increasing economic significance. Beyond their economic role, UCGs serve as vital social spaces and may be categorized as third places—informal gathering spaces that foster social connections and promote well-being. This study analyzes and compares the impact of UCGs as third places in Toronto and São Paulo, focusing on their contributions to social cohesion, financial resilience, environmental sustainability, cultural transmission, and mental well-being. It is a review-based study utilizing publicly available data from policy documents, the academic literature, and official websites. Although the practice of community gardening has a long-standing history, the concept of gardens as third places is relatively recent, emerging in the late 1980s. In recent decades, there has been growing interest in their association not only with aesthetic and functional benefits but also with health, well-being, and social connection. UCGs are valuable not only for food production but also for fostering social interaction, preserving cultural practices, and promoting overall well-being. Cities must develop policies that strengthen community resilience by recognizing and supporting UCGs as essential third places.

The 21st century has seen marine tourism in Southeast Asia transform in response to the rapid growth of SCUBA diving and snorkeling activities in the natural environment. However, despite this level of integration between recreation and the natural environment, few assessments have ever been conducted on the biodiversity or ecosystem values and experiences of the SCUBA diving community. Therefore, we explored the awareness, preferences and priorities of this community, with a particular emphasis on investigating the role of biodiversity documentation and species discoveries in motivating recreational diving. By conducting surveys of 366 recreational divers from Thailand, we were able to identify proportional priorities, finding greater valuation towards overall ecosystem esthetics than megafauna, with species-specific dive experiences being a niche but present interest. We also investigated diver priorities based on recently described or discovered marine fauna in Thai waters, focusing on five species of hard and soft coral, seven species of sea slug, and two species of shark. Of these, sea slug species were the most recognized and garnered the greatest potential economic value, likely due to their popularity with photographers. The results of this multidisciplinary investigation highlight the economic value of taxonomy and biodiversity research to the recreational SCUBA community.

In the context of the deep transformation of population structure and the coordinated advancement of high-quality development, exploring the mechanism of the impact of aging on economic growth has become a major issue related to the sustainable development of China. This study takes the 41 cities of the Yangtze River Delta urban agglomeration as a sample, using the population and economic census data from 2000 to 2020. It comprehensively applies an improved Solow model, GIS spatial analysis, spatial econometric models, and mediation effect tests to arrive at the following findings: (1) There is a significant asynchrony between economic growth and population aging in the Yangtze River Delta urban agglomeration. Economic growth has shifted from high-speed to high-quality development, while the aging process is accelerating and becoming more aged. (2) Population aging in the Yangtze River Delta has a nonlinear positive impact on economic growth. The intensity of this impact shows a characteristic of “strong-weak-strong,” with the first aging rate threshold being 11.63% and the second being 17.53%. (3) There is significant spatial autocorrelation between population aging and economic growth in the Yangtze River Delta urban agglomeration. The overall direction of the effect shows a spatial distribution pattern of “positive in the south and negative in the north.” The deepening of population aging in neighboring areas promotes local economic growth. (4) Labor productivity and optimization of the living environment constitute the core transmission pathways. Together, they account for more than 80% of the contribution and serve as the key mechanism for transforming aging pressures into growth momentum. This research provides practical guidance for solving the “rich” and “aging” contradictions in the Yangtze River Delta. It also offers a universal theoretical framework and a Chinese solution for aging economies worldwide to address the risk of growth stagnation.

This study evaluates the effectiveness of the B Impact Assessment (BIA) as a catalyst for integrating sustainability into industrial firms through a qualitative case study of LC Paper, the first B Corp-certified tissue manufacturer globally and a pioneer in applying BIA in the pulp and paper sector. Based on semi-structured interviews, organizational documents, and direct observation, this study examines how BIA influences corporate governance, environmental practices, and stakeholder engagement. The findings show that BIA fosters structured goal setting and the implementation of measurable actions aligned with environmental stewardship, social responsibility, and economic resilience. Tangible outcomes include improved stakeholder trust, internal transparency, and employee development, while implementation challenges such as resource allocation and procedural complexity are also reported. Although the single-case design limits generalizability, this study identifies mechanisms transferable to other firms, particularly those in environmentally intensive sectors. The case studied also illustrates how leadership commitment, participatory governance, and data-driven tools facilitate the operationalization of sustainability. By integrating stakeholder and institutional theory, this study contributes conceptually to understanding certification frameworks as tools for embedding sustainability. This research offers both theoretical and practical insights into how firms can align strategy and impact, expanding the application of BIA beyond early adopters and into traditional industrial contexts.

Biochar, a carbon-rich material derived from biomass, presents a sustainable solution to several pressing challenges in U.S. agriculture, including soil degradation, carbon emissions, and waste management. Despite global advancements, the U.S. biochar market remains underexplored in terms of economic viability, adoption potential, and sector-specific applications. This narrative review synthesizes two decades of literature to examine biochar’s applications, production methods, and market dynamics, with a focus on its economic and environmental role within the United States. The review identifies biochar’s multifunctional benefits: enhancing soil fertility and crop productivity, sequestering carbon, reducing greenhouse gas emissions, and improving water quality. Recent empirical studies also highlight biochar’s economic feasibility across global contexts, with yield increases of up to 294% and net returns exceeding USD 5000 per hectare in optimized systems. Economically, the global biochar market grew from USD 156.4 million in 2021 to USD 610.3 million in 2023, with U.S. production reaching ~50,000 metric tons annually and a market value of USD 203.4 million in 2022. Forecasts project U.S. market growth at a CAGR of 11.3%, reaching USD 478.5 million by 2030. California leads domestic adoption due to favorable policy and biomass availability. However, barriers such as inconsistent quality standards, limited awareness, high costs, and policy gaps constrain growth. This study goes beyond the existing literature by integrating market analysis, SWOT assessment, cost–benefit findings, and production technologies to highlight strategies for scaling biochar adoption. It concludes that with supportive legislation, investment in research, and enhanced supply chain transparency, biochar could become a pivotal tool for sustainable development in the U.S. agricultural and environmental sectors.

Natural Climate Solutions (NCSs) represent a critical tool for addressing climate change, yet their long-term success is threatened by inadequate consideration of community impacts in current verification standards. While Article 6 of the Paris Agreement establishes rigorous requirements for carbon sequestration and emission avoidance verification, existing standards lack comprehensive frameworks for assessing and ensuring community well-being, undermining project permanence and market confidence. We developed an integrated framework combining community well-being assessment with verification requirements through analysis of Article 6 implementation requirements, existing voluntary carbon offset credit standards, emerging national standards, and community engagement mechanisms. Our analysis yielded a framework establishing five core tenets for community engagement (inclusion, engagement, contribution, ownership, and well-being) and nine essential well-being assessment domains, each with specific measurable indicators. The framework provides clear verification alignment protocols that integrate with existing standards while maintaining rigorous requirements and offering practical implementation guidance. Integration of community well-being assessment into NCS verification standards strengthens project permanence while meeting verification requirements, providing practical tools for standards bodies, project developers, and market participants to ensure both environmental and social benefits. As Article 6 mechanisms mature, this integration becomes increasingly crucial for project success.

In the Sahelian context characterized by the increasing scarcity of forage resources, this study investigated how climate change perceptions influence the adoption of cottonseed cake in pastoral and agro-pastoral systems in the Hauts-Bassins region of Burkina Faso. Drawing on the Subjective Expected Utility (SEU) theory and using a logit model estimated from survey data collected from 366 livestock farms, the analysis reveals that the perceived degradation of rangelands due to climate change is a key determinant of adoption. Over 40% of surveyed herders believed that climate change is negatively affecting the availability of natural forage. This heightened awareness is significantly associated with a greater likelihood of adopting cottonseed cake as a feed supplementation strategy. This study highlights the crucial role of cognitive factors in shaping adaptation decisions, beyond traditional economic and structural determinants. It underscores the importance of incorporating environmental perceptions into public policies supporting livestock systems and technological innovations in pastoral.

This article presents an initial effort to systematize two interrelated research fronts within ecological economics (EE): ecological microeconomics and ecological macroeconomics. In response to the field’s transdisciplinary and plural nature—attributes that, while enriching, may limit its political influence—the article proposes a conceptual delineation of these two domains as a means to strengthen EE’s analytical identity and facilitate dialogue with other economic approaches. Ecological microeconomics focuses on the material and energy intensity of economic activity, the complementarity of natural capital in production processes, and the redesign of consumption and firm behavior under ecological constraints. Ecological macroeconomics, in turn, centers on the biophysical limits to growth, the concept of sustainable and optimal scale, and the integration of environmental variables into macroeconomic indicators and policy frameworks. The article argues that both fronts, despite their distinct emphases, are united by the need for long-term structural change and a normative commitment to sustainability. Together, they offer a coherent basis for rethinking prosperity within the ecological boundaries of the Earth system.

The present study was conducted in Dacope Upazila, a sub-district located within the Khulna District of the coastal region in Bangladesh. The research methods employed included the implementation of 350 household questionnaire surveys (HQSs), 12 focus group discussions (FGDs), and 20 key informant interviews (KIIs) to assess economic security status in disaster-vulnerable areas. The findings indicate that the economic well-being of the region is precarious due to a paucity of revenue sources and the occurrence of various calamitous events, induced risks, and vulnerabilities. To achieve long-term economic security for households, a considerable proportion of the population (approximately 22%) in the study areas is dependent on agricultural activities for their livelihoods. The study also revealed that approximately 22% of households in the study areas reported experiencing salinity intrusion. Furthermore, most of the households, around 68%, reported cyclones as their primary obstacle to building disaster-resilient communities. Consequently, the prevailing local and institutional strategies to ensure economic security were found to be inadequate and unsustainable in the study upazila. Therefore, the study resulted in the formulation of a conceptual framework intended to measure the contribution of economic security to the adaptability and sustainability of disaster-resilient communities in vulnerable coastal areas of Bangladesh.

In the socio-institutional framework of the Minangkabau society in West Sumatra, Indonesia—where women are typically assumed to have full power over land due to the matrilineal system of land ownership—this study asks: To what extent do women actually exercise power over land ownership and decision-making, and what factors influence this power? Comprising 212 households, a methodical household survey carried out in 2024 across the regencies of Lima Puluh Kota and Padang Pariaman employed quantitative approaches and comparative analysis across rural and peri-urban areas. The survey results confirm the initial hypothesis, showing high rates of land ownership among women in West Sumatra, largely attributed to the matrilineal system. Land ownership by itself, though, does not significantly increase women’s influence in households. Rather, women’s decision-making in Lima Puluh Kota is strongly influenced by other assets such as ownership of cattle, poultry, and electronic items; in Padang Pariaman, time allocated to farming and social events has more influence. These findings underline the complex reality behind nominal land rights and practical empowerment, thereby stressing the need to consider broader socioeconomic factors. The report advises more research on how religious interpretations and modernization are altering West Sumatra’s customary matrilineal customs and women’s empowerment.

Tropical peatlands store approximately 105 gigatons of carbon (GtC), serving as vital long-term carbon sinks, yet remain critically underrepresented in climate policy. Indonesia peatlands contain 57GtC—the largest tropical peatland carbon stock in the Asia–Pacific. However, decades of drainage, fires, and lax enforcement practices have degraded vast peatland areas, turning them from carbon sinks into emission sources—as evidenced by the 1997 and 2015 peatland fires which emitted 2.57 Gt CO2eq and 1.75 Gt CO2eq, respectively. Using system theory validated against historical data (1997–2023), we develop a causal loop model revealing three interconnected feedback loops driving irreversible collapse: (1) drainage–desiccation–oxidation, where water table below −40 cm triggers peat oxidation (2–5 cm subsistence) and fires; (2) fire–climate–permafrost, wherein emissions intensify radiative forcing, destabilizing monsoons and accelerating Arctic permafrost thaw (+15% since 2000); and (2) economy–governance failure, perpetuated by palm oil’s economic dominance and slack regulatory oversight. To break these vicious cycles, we propose a precautionary framework featuring IoT-enforced water table (≤40 cm), reducing emissions by 34%, legally protected “Global Climate Stabilization Zones” for peat domes (>3 m depth), safeguarding 57 GtC, and ASEAN transboundary enforcement funded by a 1–3% palm oil levy. Without intervention, annual emissions may reach 2.869 GtCO2e by 2030 (Nationally Determined Contribution’s business-as-usual scenario). Conversely, rewetting 590 km2/year aligns with Indonesia’s FOLU Net Sink 2030 target (−140 Mt CO2e) and mitigates 1.4–1.6 MtCO2 annually. We conclude that integrating peatlands as irreplaceable climate infrastructure into global policy is essential for achieving Paris Agreement goals and SDGs 13–15.

Under the impetus of the global urbanization, the synergistic relationship between smart city policies and green innovation capabilities has emerged as a critical agenda for achieving sustainable development goals. While existing studies have explored the techno-economic effects of smart cities, systematic evidence remains scarce regarding their pathways and heterogeneous impacts on green growth. This study investigates the influence of smart city pilot policies on urban green growth trajectories and their heterogeneous characteristics. Leveraging panel data from 293 Chinese prefecture-level cities, we employ a multi-period difference-in-differences (DID) model with two-way fixed effects to control for unobserved city-specific and time-specific factors, complemented by robustness checks including parallel trend tests, placebo tests, and alternative dependent variable specifications. Data sources encompass the China City Statistical Yearbook, CNRDS, and CSMAR databases, covering core metrics such as green patent applications and grants, industrial upgrading indices, and environmental regulation intensity, with missing values being addressed via mean imputation. The findings demonstrate that smart city pilot policies significantly enhance green innovation levels in treated cities, with effects exhibiting pronounced spatial and resource-based heterogeneity; there are notably stronger impacts in non-resource-dependent cities and eastern regions. Mechanism analysis shows that policies are driven by a dual effect of industrial upgrading and environmental regulation. The former is manifested by the high substitution elasticity of the digital economy for traditional manufacturing, while the latter is reflected in the rising compliance costs of polluting enterprises. This research advances a cross-nationally comparable theoretical framework for understanding green transition mechanisms in smart city development while providing empirical benchmarks for policy design in emerging economies.

The growing relevance of sustainable practices has driven organizations from various sectors to adapt their activities to current socio-environmental demands. In the construction sector, this demand is even more pronounced due to the high consumption of natural resources and the significant generation of solid waste. However, questions remain about the extent to which companies in this sector understand and incorporate sustainable practices into their routines. This study investigates the level of knowledge and the adoption of sustainable practices by residential building construction companies registered with the Civil Construction Industry Union of Mossoró/RN. A qualitative-quantitative approach was adopted, using questionnaires and photographic records collected during on-site visits. The data reveal an incipient adoption of Environmental Management Systems (EMSs) and limited knowledge about ESG principles, highlighting structural and cultural barriers to sustainability in the sector. Nevertheless, isolated initiatives related to waste reduction and the adoption of more efficient practices were observed. The study concludes that strengthening technical training, promoting management systems, and aligning with contemporary demands are relevant strategies to foster sustainability and competitiveness in the construction sector.

Greenhouse gases, such as carbon dioxide (CO2), released from excessive fossil fuel consumption, are major contributors to global warming. Understanding the spatial distribution of CO2 emissions on a refined scale is crucial for promoting green economic development. Xi’an, a key central city in China, serves as the case study for this research. Using nighttime light data from Black Marble, combined with energy statistics and socio-economic information, this study employed spatial analysis to simulate CO2 emissions on the district and county levels in Xi’an for the years 2012 and 2022. The results indicated that nighttime light data were significantly correlated with CO2 emissions (linear function; coefficients of determination: 0.7838 and 0.7941 for 2012 and 2022, respectively). The spatial distribution analysis revealed a clear pattern in CO2 emissions, with higher emissions concentrated in central urban areas and lower emissions in peripheral regions. Additionally, a comparative analysis of carbon emissions and carbon emission intensity across districts and counties between 2012 and 2022 showed that CO2 emissions in central urban areas had continued to grow and expand, while emission intensity had declined. These findings suggest that the socio-economic development, policy interventions, and industrial structure in Xi’an influence the spatial distribution of CO2 emissions.

With the rapid development of China’s economy, resource consumption and environmental pollution have become challenges faced by China in its development process. In order to effectively achieve a balance between economic development and ecological and environmental protection, the Chinese government has successively introduced development strategies for ecological environment construction. However, how to scientifically evaluate the quality of regional ecological environments, analyze related impacts, and promote national ecological and environmental governance has always been difficult to reach consensus and continues to receive attention from the academic community. This paper sorts through research in recent years about regional ecological environment assessments in China in order to summarize the current assessment methods and dimensions of regional ecological environment research in China, as well as the impact of regional ecological environment construction. In terms of evaluation methods, this paper analyzes the applicability and limitations of current mainstream methods. In terms of evaluation dimensions, this paper summarizes the research results from different regional dimensions. In terms of the impact of regional ecological and environmental construction, this paper elaborates on the three aspects of influencing factors, influencing effects and research method analysis. Based on the above analysis, this paper finally proposes that the focus of future research should be on digital analysis and the evaluation of regional ecological and environmental quality, so as to provide more scientific and accurate support for regional ecological and environmental governance.

As the flow of innovation elements breaks through geographical boundaries, patent transfer and the resulting spatial knowledge spillovers have become a crucial pathway for cities to enhance their competitive advantages and foster collaborative innovation. This study crawls technology transfer data through Big Data mining and uses social network analysis to construct an intercity technology transfer network among 286 Chinese cities at the prefecture-level and above between 2000 and 2020. The study explores the influence of technology transfer networks and their spatial spillovers on urban innovation capacity. The results are as follows: (1) Moran’s I results indicate that technology transfer and innovation activities among Chinese cities exhibit significant spatial dependence. (2) The Markov chain analysis reveals that the technology transfer networks among Chinese cities exhibit significant spatial spillovers. (3) Spatial econometric analysis and effect decomposition demonstrate that technology transfer networks exhibit significant spatial dependence and spillover effects. Through the induced spatial knowledge spillovers, technology transfer networks contribute to enhancing the innovation capabilities of neighboring cities.

Subsidized, decent, and durable housing is a persistent issue for South Africa’s urban areas. Social housing is one of the most important instruments for addressing the situation, yet structural barriers such as land prices, bureaucracy, and governance pose a challenge to forward momentum. This study provides a qualitative examination of social housing in Durban, Cape Town, and Johannesburg on the basis of three dimensions: effectiveness of governance, land accessibility, and practice of sustainability. It is evident that land acquisition is still a great hindrance due to private stakeholder opposition, complex rezoning processes, and speculative ownership of land. Institutional systems within the three cities are characterized by poor intergovernmental coordination, a lack of transparency in land disposition, and lengthy project approval. Johannesburg has seen extensive transit-oriented development, while Cape Town is more advanced in sustainability initiatives, albeit with a resource constraint, and Durban’s human-scale housing types suffer from finance and technical capacity challenges. This study underscores the need for interlinked policy changes to bridge the inefficiencies in governance, facilitate land accessibility, and enhance the incentives of sustainability. An across-the-board data-driven process involving government authorities, private builders, and civil society stakeholders is indispensable in advocating effective and sustainable urban housing strategies for South Africa.

This study examines how research and development (R&D) expenditures, temperature fluctuations, and rainfall variability influenced wheat productivity in China, India, and Pakistan from 1996 to 2018. Drawing on data from FAOSTAT, the Pakistan Economic Survey, and World Development Indicators, we employ Pooled Mean Group (PMG) and Autoregressive Distributed Lag (ARDL) models to explore short- and long-run dynamics. Our findings indicate that R&D investments do not exert a significant short-run effect but play a pivotal role in boosting wheat yields over the long run. Specifically, a 1% increase in R&D expenditure correlates with a 10% rise in wheat productivity across the three countries, although the returns vary—6% in China, 17% in India, and 12% in Pakistan—due in part to differences in innovation adoption and infrastructure. Additionally, a 1% temperature rise is associated with a 4% decrease in long-run yield, while variability in rainfall disrupts sowing schedules and reduces water availability during critical growth stages, further constraining productivity. These findings underscore that while climate factors pose significant risks to wheat yields, sustained investments in agricultural R&D and improved resource management are essential for enhancing food security in South Asia.

The close association between policy deployment in ecotourism demonstration areas and low-carbon tourism makes it imperative to explore whether such policies can effectively curb carbon emissions in the tourism sector. This study utilizes an evolutionary game model to theoretically analyze the mechanisms of stakeholders’ strategic tendencies following policy deployment in ecotourism. Empirically, using panel data from 276 prefecture-level cities across China from 2010 to 2019, the establishment of ecotourism demonstration areas was treated as a “quasi-natural experiment”. A multi-period difference-in-differences model was employed to evaluate the inhibitory effects of the policy on tourism carbon emissions and its underlying pathways in the establishment of ecological tourism demonstration zones. The theoretical mechanism reveals that, after the deployment of ecotourism demonstration area policies, local governments, tourism enterprises, and tourists tend to choose low-carbon strategic behaviors. Empirical analysis reveals that ecotourism demonstration areas effectively curb carbon emissions in the tourism industry. The inhibitory effect of the policy exhibits regional heterogeneity, with a significant impact on carbon emission reduction in eastern cities. The policy exerts its inhibitory effects on tourism carbon emissions through increased ecological tourism investment by local governments and self-scaling cointegration by tourism enterprises.

Good solutions for sustainable development promote social, ecological, and economic aspects in synergistic ways. Wind energy projects have a large potential to achieve this, if their locations are carefully selected. On the contrary, placing wind turbines inside forest areas with high biodiversity, cultural significance, and recreational use generates conflicts between different dimensions of sustainability, and between supporters and opponents of such projects. The resulting green-versus-green dilemma involves a conflict between idealism and pragmatism, as incorporated in literature by the personalities of Don Quixote and Sancho Panza. Sustainable solutions require both aspects as well as realism. Forest areas have crucial climate benefits ranging from the absorption of CO2 and other emissions, providing shade and cooling during heatwaves to the storage of humidity and water. Climate change is not solely a problem of rising temperature. It also involves changes in humidity and precipitation, and the related problems of desertification and deforestation. Accordingly, a strategy of deforestation for hosting wind farms seems questionable. Instead, constructing wind turbines with energy storage capacities on deserted ground and using their economic and energetic gains for a subsequent afforestation of the surrounding land would achieve synergetic sustainability benefits for biodiversity, human wellbeing, and the climate.

This paper explores the effects of the cessation of forest commodity exports and the implementation of an industrialization strategy in Gabon, drawing on traditional theories of regional growth. The creation of the Nkok Special Economic Zone (SEZ) in 2012, accompanied by its strategic location and significant infrastructure investments, illustrates the application of Rosenstein-Rodan’s “Big Push” and Douglass-North’s “export base” theories. These initiatives also led to a polarization process consistent with the work of Perroux and other theorists of unbalanced regional growth. The study assesses the impact of this SEZ on regions external to the SEZ and the macroenvironment during the period 2014–2022. It highlights the industrial and commercial mechanisms that promote agglomeration economies, technological diffusion, the creation of economic connections, and the structuring into “core-periphery” zones, in accordance with the concepts of Hirschman. The results show a strong positive correlation between industrial income, exports (excluding raw materials), and industrial production. However, the ban on the export of wood raw materials led to a negative relationship between industrial income and exports of these products. Furthermore, the local processing of forest products has promoted industrial diversification, generated new products, and gradually increased added value. The process of economic and geographical polarization is described as a transitional phase of imbalances whose long-term implications require in-depth studies, particularly in the context of countries in the South and underdeveloped environments.

Rural tourism has emerged as a significant option to meet the people’s growing needs for a better life in the new era. Evaluating the competitiveness of the rural tourism industry plays a crucial role in promoting rural revitalization. This article is based on a modified Porter’s diamond model. This study focuses on representative rural tourism demonstration areas in the upper, middle, and lower reaches of the Yangtze River Economic Belt, specifically Wenjiang District in Chengdu, Huangpi District in Wuhan, and Jiangning District in Nanjing. The Delphi method and the Analytic Hierarchy Process were employed to construct a competitiveness evaluation index system for rural tourism and to assign weights. This article evaluates and compares the competitiveness of the rural tourism industry in the case study regions. This research reveals that the competitiveness of the rural tourism industry in the Yangtze River Economic Belt exhibits a pattern of strong competitiveness in the middle reaches, weaker competitiveness in the upper reaches, and moderate competitiveness in the lower reaches. These differences are significantly influenced by the region’s tourism resource endowments, tourism infrastructure, and market scale. Huangpi District demonstrates strong competitiveness in its rural tourism industry. This strength is attributed to its well-developed rural tourism supply system. Jiangning District has moderate competitiveness in its rural tourism industry. This is supported by a strong market demand and a relatively complete tourism support system. Wenjiang District shows weaker competitiveness in its rural tourism industry. This weakness results from a fragile rural tourism supply system and a sluggish market demand. This article concludes with recommendations for enhancing the competitiveness of rural tourism in the Yangtze River Economic Belt.

This study explores the relationships between the digital economy, R&D investment, and carbon emissions, as well as the mediating role of financial technology (fintech). Despite a growing body of research, the impact of the digital economy on carbon emissions remains contested, partly due to the limited scope and inconsistent measures in existing studies. Additionally, while R&D is a pivotal driver of modern development, its potential quadratic effects on carbon emissions in China remain unexplored. By employing a comprehensive Digital Economy Index and analyzing panel data from 2011 to 2020 across Chinese regions, this study provides new insights into how digitalization and innovation influence carbon emissions. The findings reveal a positive linear correlation between the digital economy and CO2 emissions over the last decade. Moreover, R&D investments exhibit an inverse U-shaped relationship with emissions, acting as an effective factor in reducing CO2 emissions. Notably, the turning point of this relationship occurs in Quadrant I, where most regions are clustered, indicating substantial efficiency gains from early-stage R&D investments and their significant potential to enhance sustainable development. Furthermore, fintech emerges as a significant mediator in the R&D–emissions dynamic, underscoring its critical role in this context.

Promoting green innovation is an important way to implement the dual carbon strategy and build an innovative country. Based on the panel data of 250 cities in China from 2011 to 2018, this paper constructs a two-way fixed-effect model, an intermediary effect model and a spatial Durbin model, and empirically studies the impact and mechanism of digital finance on urban green innovation. The results show that digital finance can improve the ability of urban green innovation, and its enabling effect mainly comes from improving the financial service model and improving the digital level. However, the role of digital finance in improving the efficiency of green innovation is not significant. Digital finance can promote urban green innovation by promoting the development of the Internet and alleviating the distortion of labor factors. A good environment for innovation will enhance the role of digital finance in promoting green innovation. Through further analysis, the spatial spillover effect of digital finance on green innovation at this stage is dominated by the siphon effect while the “trickle-down” effect is blocked.

As a branch of regional innovation theories, social filter theory fundamentally reveals the reasons behind the geography of innovation in different countries and regions. However, compared with other regional innovation theories, social filter theory has remained largely ignored and has not been fully developed. To enrich and develop social filter theory, this article systematically traces its origins and comments on four aspects: the concept of social filters, the construction and measurement of social filter indicators, the mechanisms, and empirical research on how social filters affect regional innovation and the transformation of innovation. Until recently, regional innovation theories primarily focused on superficially describing the phenomenon of innovation, but they paid little attention to the local social filter conditions necessary for innovation generation and transformation, which are prerequisites for constructing a mature innovation system. Therefore, further efforts are needed to address the current knowledge gap based on the recommended directions in this article.

Spatial distribution is a critical factor influencing the success or failure of hotel management. This study examines the spatial distribution patterns of foreign star-rated hotels in China from 2000 to 2015 based on 27 typical city cases, using global and local spatial autocorrelation methods within GIS spatial analysis. The research explores the evolution of these patterns, analyzes key characteristics, and combines these insights with a stepwise regression method. Pearson correlation analysis is used to identify factors that influence the evolution of the spatial pattern. This study reveals that, first, the Z-value of global spatial autocorrelation of foreign star-rated hotels in China decreases from 2.38 to 1.63, indicating that the spatial distribution of foreign star-rated hotels in China has shifted from imbalanced to balanced, transitioning from economically developed regions such as areas with overseas Chinese populations, provincial capitals, and municipalities directly under central government control, toward tourist cities. Second, star-rated hotels hold a critical position within the spatial pattern, highlighting their central role in shaping the hospitality landscape. Third, the spatial distribution of foreign star-rated hotels is primarily influenced by the number of inbound tourists, followed by the presence of scenic spots rated 4A and above. The influence of other factors is found to be less significant. Fourth, the correlation coefficient between tourism demand and foreign star-rated hotels increased by 0.004, whereas the correlation coefficient between tourism supply and foreign star-rated hotels decreased by 0.036, indicating that market factors are playing an increasingly important role in shaping the evolution of foreign star-rated hotels in China, reflecting broader market dynamics. This study provides practical guidance for local Chinese hotels facing competition from foreign-funded establishments and offers theoretical insight into the strategic implementation of transnational operations. It points out the expansion direction of local Chinese hotels across different developmental stages.

Fishery plays an important role in world trade; however, the embodied energy associated with fishery remains incompletely quantified. In this study, we applied the multi-regional input-output (MRIO) model and logarithmic mean Divisia index (LMDI) approach to understand the evolution and drivers of embodied energy in the intermediate and final fishery trade between China and countries along the 21st century Maritime Silk Road (MSR) from 2006 to 2021. The findings are as follows: (1) Embodied energy in the intermediate fishery trade averaged 92.2% of embodied energy from the total fishery trade. China has gradually shifted from being a net exporter to a net importer of embodied energy in intermediate, final, and total fishery trade with countries along the MSR. (2) From a regional perspective, the embodied energy in China’s fishery trade with Japan, South Korea, and Southeast Asia comprises the majority of the embodied energy from China’s total fishery trade (82.0% on average annually). From a sectoral perspective, petroleum, chemical and non-metallic mineral products, and transport equipment were prominent in the embodied energy of China’s intermediate fishery trade (64.0% on average annually). (3) Economic output increases were the main contributors to the increasing embodied energy in all types of fishery trade in China. The improvement in energy efficiency effectively reduced the embodied energy in all types of fishery trade in China, but its negative driving force weakened in recent years owing to minor energy efficiency improvements. Understanding the embodied energy transactions behind the intermediate and final fishery trade with countries along the MSR can provide a theoretical reference for China to optimize its fishery trade strategy and save energy.

Helium, as a by-product of the natural gas industry, will be impacted by the decline in consumption of fossil fuels as the world moves towards net-zero carbon emissions. In September 2022, all assets relating to the US government’s previous helium industry were sold. In the US, helium is now only available from private suppliers. In June 2022, Russia banned the export of helium to “unfriendly” countries, highlighting the geopolitical issues surrounding the industry. In the past, helium was popularized, and the industry was supported by its military applications (filling dirigible aircraft, welding fighter jets and purging rocket engines). It also plays an important role in supporting present-day technologies (e.g., MRI machines and spectroscopy) and will also be important for a high-tech future (e.g., in quantum computing, fusion power, and space exploration). Shortages of helium will inevitably cause skyrocketing prices and consequently lead to significant challenges for research and development (as has happened in the past) and technological progress, as well as a slowdown in world economic growth and prosperity. Anticipated declines in natural gas production, associated with moves towards net-zero carbon emissions targets, make helium less accessible. While this is problematic for industry in the short term, it perhaps preserves some low entropy helium within the ground, making it more accessible to future generations. Given anticipated limitations to the future supply of helium, technological developments are currently focused on a few areas: the replacement of helium by other gases in industrial applications, changing technological approaches to not require helium, and reducing the cost of obtaining helium from the atmosphere. This paper explores the past, present and future of helium, focusing on the sustainability of the helium industry.

Education, science and technology, and talent are significant factors driving economic growth. Coordinating the integrated development of education, science and technology, and talent is not only an important way to achieve the development of education, technology, and talent themselves, but it is also a crucial path to sustainable development. The research objectives of this paper are to explore the coupling coordination relationship among the three subsystems of education, science and technology, and talent and to investigate their spatiotemporal pattern evolution characteristics. This paper, based on panel data from 30 provinces in China from 2001 to 2022, constructs an evaluation index system for “education–science and technology–talent” (EST) development from three dimensions: education, science and technology, and talent. It comprehensively employs methods such as spatiotemporal pattern evolution, LISA time path, and spatial transitions to evaluate the level of China’s EST. The results indicate the following: (1) During the research period, the level of China’s EST shows a significant upward trend, with the educational subsystem being the most prominent. (2) The level of China’s EST development has a significant spatial differentiation characteristic, generally showing a decreasing trend from the eastern to the central and western regions. (3) In terms of the stability of the spatiotemporal pattern, the spatial pattern of China’s EST development is relatively stable, and there is no significant spatial shift during the research period. This study provides a new method for the evaluation of complex systems and also offers a reference for the economic growth of many developing countries.

This paper presents an urban resilience evaluation index system and evaluation on the clustering of educational resources based on the data of 80 prefecture-level cities in China’s central region in 2012, 2016, and 2020. The results reveal a rising trend of urban resilience in the central region of China, with the provincial capital cities exhibiting the highest levels of resilience. Educational resources are clustered in urban areas of provincial capital cities and other prefectural-level cities. Furthermore, clustering of educational resources has a significant impact on urban resilience. Policy factors play a significant role in moderating the relationship between educational resource clustering and urban resilience in large cities; however, this moderating role is not significant in small cities. These findings have significant implications for the optimal allocation of educational resources, promotion of urban resilience, and advancement of social equity.

In an era of global economic slowdown, effectively stimulating urban economic development has become a critical challenge for governments around the world. Based on the panel data of 280 prefecture-level cities in China from 2006 to 2017, this study adopts the double-difference method to evaluate the impacts of innovative cities pilot policies on urban economic growth, explore the mechanism through the intermediary effect model, and study the heterogeneity of cities with different development endowments by sub-samples. This study shows the following: (1) The policy of innovative pilot cities has significantly promoted their economic growth: GDP growth rates in the pilot cities are 1.14 percent higher than those in non-pilot cities. (2) The innovative city policy can effectively improve technological progress and human capital, thereby promoting economic growth. (3) The promotion effect of the pilot policy on the economy varies by region, city size, administration grade, market level, and government efficiency. Specifically, the policies have the most substantial positive effects in cities with lower administrative levels, smaller sizes, less market orientation, and higher government efficiency. This research, based on the city data from the world’s largest economy, evaluates the impact of government intervention—targeted urban innovation policies—on economic development, providing valuable insights into how innovation policies can be tailored and optimized for diverse urban contexts.

This study examines hydrogen production across 27 European countries, highlighting disparities due to varying energy policies and industrial capacities. Germany leads with 109 plants, followed by Poland, France, Italy, and the UK. Mid-range contributors like the Netherlands, Spain, Sweden, and Belgium also show substantial investments. Countries like Finland, Norway, Austria, and Denmark, known for their renewable energy policies, have fewer plants, while Estonia, Iceland, Ireland, Lithuania, and Slovenia are just beginning to develop hydrogen capacities. The analysis also reveals that a significant portion of the overall hydrogen production capacity in these countries remains underutilized, with an estimated 40% of existing infrastructure not operating at full potential.
