Sustainable smart city and Sustainable Development Goals (SDGs): A review Z. R. M. Abdullah KAISER, Apu DEB Regional Sustainability    2025, 6 (1): 100193-.   DOI: 10.1016/j.regsus.2025.100193 Abstract （114）   HTML （6）    PDF （3150KB）（237）       Knowledge map    Save The rapid urbanization and increasing challenges are faced by cities globally, including climate change, population growth, and resource constraints. Sustainable smart city (also referred to as “smart sustainable city”) can offer innovative solutions by integrating advanced technologies to build smarter, greener, and more livable urban environments with significant benefits. Using the Web of Science (WoS) database, this study examined: (i) the mainstream approaches and current research trends in the literature of sustainable smart city; (ii) the extent to which the research of sustainable smart city aligns with Sustainable Development Goals (SDGs); (iii) the current topics and collaboration patterns in sustainable smart city research; and (iv) the potential opportunities for future research on the sustainable smart city field. The findings indicated that research on sustainable smart city began in 2010 and gained significant momentum in 2013, with China leading, followed by Italy and Spain. Moreover, 59.00% of the selected publications on the research of sustainable smart city focus on SDG 11 (Sustainable Cities and Communities). Bibliometric analysis outcome revealed that artificial intelligence (AI), big data, machine learning, and deep learning are emerging research fields. The terms smart city, smart cities, and sustainability emerged as the top three co-occurring keywords with the highest link strength, followed by frequently co-occurring keywords such as AI, innovation, big data, urban governance, resilience, machine learning, and Internet of Things (IoT). The clustering results indicated that current studies explored the theoretical foundation, challenges, and future prospects of sustainable smart city, with an emphasis on sustainability. To further support urban sustainability and the attainment of SDGs, the future research of sustainable smart city should explore the application and implications of AI and big data on urban development including cybersecurity and governance challenges.

This study used the Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost Ratio (BCR), and payback period to evaluate the economic viability of the adopted CSA interventions in the three villages (Doggoh, Jeffiri, and Wulling) of the dryland farming systems of northern Ghana, where CSA interventions were mostly practiced. Data were collected from 161 farm households by the questionnaire survey. The results showed that CSA interventions including livestock-crop integration, mixed cropping, crop rotation, nutrient integration, and tie ridging enhanced crop yield and the household income of smallholder farmers. The five CSA interventions selected by smallholders were in the following order of priority: livestock-crop integration (BCR=2.87), mixed cropping (BCR=2.54), crop rotation (BCR=2.24), nutrient integration (BCR=1.98), and tie ridging (BCR=1.42). Results further showed that livestock-crop integration was the most profitable CSA intervention even under a pessimistic assumption with a long payback period of 5.00 a. Moreover, this study indicated that the implementation of CSA interventions, on average, was relatively profitable and had a nominal financial risk for smallholder farmers. Understanding the economic viability of CSA interventions will help in decision-making process toward selecting the right CSA interventions for resilience development.

Green hydrogen production from wind energy in Far Eastern Federal District (FEFD), the Russian Federation Mihail DEMIDIONOV Regional Sustainability    2025, 6 (1): 100199-.   DOI: 10.1016/j.regsus.2025.100199 Abstract （84）   HTML （4）    PDF （1184KB）（16）       Knowledge map    Save There is a gradual increase in the proportion of renewable energy sources. Green hydrogen has the potential to become one of the major energy carriers in the future. The Russian Federation, in partnership with countries in the Asia-Pacific region and especially China, has the potential to play a significant role in green hydrogen market. This study assessed the potential of developing green hydrogen energy based on wind power in the Far Eastern Federal District (FEFD) of the Russian Federation. Empirical wind speed data were collected from 20 meteorological stations in 4 regions (Sakhalinskaya Oblast’, Primorskiy Krai, Khabarovskiy Krai, and Amurskaya Oblast’) of the FEFD. The Weibull distribution was used to predict the potential of green hydrogen production. Five different methods (Empirical Method of Justus (EMJ), Empirical Method of Lysen (EML), Maximum Likelihood Method (MLE), Power Density Method (PDM), and Median and Quartiles Method (MQM)) were used to determine the parameters (scape factor and scale factor) of the Weibull distribution. We calculated the total electricity generation potential based on the technical specifications of the three wind turbines: Senvion 6150 onshore, H165-4.0 MW, and Vestas V150-4.2 MW. The results showed that Vladivostok, Pogibi, Ilyinskiy, Yuzhno-Kuril’sk, Severo-Kuril’sk, Kholmsk, and Okha stations had the higher potential of green hydrogen production, of which Vladivostok exhibited the highest potential of green hydrogen production using the wind turbine of H165-4.0 MW, up to 2.56×105 kg/a. In terms of economic analysis, the levelized cost of hydrogen (LCOH) values of lower than 4.00 USD/kg were obtained at Yuzhno-Kuril’sk, Ilyinskiy, Pogibi, and Vladivostok stations using the wind turbine of H165-4.0 MW, with the values of 3.54, 3.50, 3.24, and 2.55 USD/kg, respectively. This study concluded that the FEFD possesses significant potential in the production of green hydrogen and, with appropriate investment, has the potential to become a significant hub for green hydrogen trading in the Asia-Pacific region.

Qualitative assessment of the impact of waste littering and dumping on surface water quality in Nigeria Gloria FAYOMI, Ednah ONYARI, Onyeka NKWONTA Regional Sustainability    2025, 6 (1): 100194-.   DOI: 10.1016/j.regsus.2025.100194 Abstract （73）   HTML （5）    PDF （824KB）（157）       Knowledge map    Save Water resources are vital for all living beings and should be managed properly to ensure the safety and well-being of humankind. Surface water bodies are constantly faced with serious contamination risks generated primarily by human activities and urbanization. The problem of waste littering and dumping in developing countries like Nigeria is increasingly affecting environmental resources such as air and water. Several studies have revealed alarming levels of heavy metals that exceed the World Health Organization (WHO) standards. Plastic waste represents a substantial portion of litter, affecting water quality. Pollution results in the depletion of aquatic ecosystems and an increase in water-related diseases. This review aims to assess the impact of waste littering and dumping on surface water quality in Nigeria. In this review, the findings of various studies on surface water bodies in Nigeria, particularly those under the influence of urbanization and waste disposal, were compiled. This review compared numerous physical and chemical parameters like pH, dissolved oxygen, and heavy metals, and microbiological properties such as total coliforms. The water quality index (WQI) was also computed in these studies to ascertain the suitability of the water samples for human consumption. Review results showed that numerous water bodies in Nigeria have significantly diverse water quality levels, with some samples meeting or exceeding the WHO guidelines for microbiological, chemical, and physical characteristics. Notably, levels of heavy metals, turbidity, and pH frequently exceeded permissible limits, pointing to contamination from agricultural and industrial sources. The WQI results for multiple locations revealed that the majority of surface water sources were classified as “bad” to “very bad”, meaning they were unfit for human consumption. The results emphasized the critical need for immediate action to prevent further harm and deterioration of surface water bodies in Nigeria. Recommendations include strengthening waste management policies, promoting recycling initiatives, fostering collaborations among stakeholders, developing littering penalties and enforcing fines to curb the challenge, and raising educational awareness from the primary level. This review emphasizes the need for proactive measures to protect the environment and surface water quality in Nigeria. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Innovation in two contrasting value chains: Constraints and opportunities for adopting alternative crop production in the Vietnamese Mekong River Delta Sang Thanh LE, Nhu Huynh MAO, Paul KRISTIANSEN, Michael COLEMAN Regional Sustainability    2025, 6 (1): 100198-.   DOI: 10.1016/j.regsus.2025.100198 Abstract （61）   HTML （7）    PDF （499KB）（5）       Knowledge map    Save Agricultural production (especially intensive rice production) is a primary income source for over 2.0×107 people in the Vietnamese Mekong River Delta. However, adverse climate change impacts, socio-economic change, and high dependence on farm inputs for intensive production constrain the longer-term sustainability of rice systems. Government and agribusiness actors are encouraging more farmers to grow non-rice crops and supporting the upscaling of alternative crops to paddy rice. We used a qualitative approach to investigate the value chain characteristics, as well as constraints and opportunities of alternative crops via two case studies (baby corn and honeydew melon) in An Giang and Hau Giang provinces, Vietnam. Data collection involved focus group discussions with local farmers and interviews with farmers and industry experts. Thematic analysis was used to compile the findings, and the results were validated with local government staff. The baby corn value chain featured on-going and stable market demand (including value-addition) and better vertical coordination (e.g., written contracts and financial support). The honeydew melon value chain featured positive relationships between farmers and traders despite less-developed vertical coordination. There are opportunities for value chain engagement through product quality certification, value-addition, and accessing high-value domestic and export markets. However, farmers require crop-specific and generic support from private and public sectors. Increased labour requirements and limited access to finance and credit limit value chain participation. Upscaling and marketing alternative crops can enhance farmer profitability and support non-farming agricultural business establishment, economic growth, and community development. Efficient value chains will be critical to ensure the adoption of alternative crops and development of crop-specific agribusiness models. These findings can inform policy-makers and change facilitators in designing targeted interventions to support the adoption of alternative crops in the study area as well as in Vietnam and globally.

Spatiotemporal characteristics and driving factors of the fractional vegetation coverage in the Ertix River Basin LIU Yixuan, Alim SAMAT, LI Wenbo, Jilili ABUDUWAILI Regional Sustainability    2025, 6 (3): 100227-.   DOI: 10.1016/j.regsus.2025.100227 Abstract （56）   HTML （4）    PDF （3219KB）（4）       Knowledge map    Save The rapid acceleration of global warming and intensifying human activities have exacerbated the fragility and climate sensitivity of ecosystems worldwide, particularly in arid regions. Vegetation, a key component of ecosystems, is critical in enhancing the ecological environment. The Ertix River Basin (ERB) is a transboundary watershed that spans multiple countries, mostly in arid regions. However, research on the fractional vegetation coverage (FVC) and its driving factors in the ERB remains limited. Investigating the spatiotemporal changes in the FVC and its relationship with various factors in the ERB can offer scientific support for optimizing regional vegetation restoration policies and promoting the coordinated development of human-environment interactions. The Moderate-resolution Imaging Spectroradiometer (MODIS) MYD13Q1 V6 data were obtained via the Google Earth Engine platform, and methods including the pixel dichotomy method, Theil-Sen median trend analysis, and Mann‒Kendall test were employed to examine the spatiotemporal dynamics of the FVC in the ERB from 2003 to 2023, with future trend forecast using the Hurst index. The impacts of natural and socioeconomic factors on the FVC were evaluated through the partial least squares-structural equation model (PLS-SEM). The results indicated that the FVC in the ERB showed a slight degradation trend with an average annual decrease of 0.046% during 2003-2023, with significant changes occurring in 2004, 2010, and 2019. Spatially, 53.380% of the study area was degraded, and the change in the FVC increased gradually from southeast to northwest. The FVC in 63.000% of the study area was highly stable and displayed long-term persistence; and the direct impact of natural factors (path coefficient of 0.617) on the FVC was significantly higher than that of socioeconomic factors (0.167). Among the natural factors, precipitation (0.999) was the most significant. This study reveals the significant impacts of natural and socioeconomic factors on vegetation dynamics in arid regions, and provides a scientific basis for transnational ecological conservation.

Renewable energy and its impact on agricultural and economic development in the Netherlands and South Africa Saul NGARAVA, Alois Aldridge MUGADZA Regional Sustainability    2025, 6 (2): 100209-.   DOI: 10.1016/j.regsus.2025.100209 Abstract （53）   HTML （5）    PDF （1081KB）（11）       Knowledge map    Save The use of renewable energy is an important way to achieve sustainable agricultural and economic development. However, there are differences in access to renewable energy between the Global North and Global South. This study utilised an autoregressive distributed lag-error correction model and the data spanning from 1991 to 2021 to comparatively analyse the dynamic relationship among renewable energy consumption, the value of agricultural production, gross domestic product (GDP), economic diversification index, urban population, the total water extraction for agricultural withdrawal, and trade balance in the Netherlands and South Africa. In the short run, renewable energy consumption was increased by the value of agricultural production but decreased by GDP in South Africa. In the long run, renewable energy consumption and GDP increased the value of agricultural production, while the value of agricultural production also increased GDP in South Africa. However, in the Netherlands, there was no short- and long-run relationship between renewable energy consumption and agricultural and economic development. The results revealed that there was a short- and long-run relationship in South Africa. Moreover, in the Netherlands, the adjustment speed was -1.46 for renewable energy consumption with an error correction of 0.68 a (8.22 months). In South Africa, the adjustment speed was -1.28 for renewable energy consumption with an error correction of 0.78 a (9.38 months). Therefore, compared to South Africa, renewable energy consumption in the Netherlands takes less time to return to balance after a shock. These findings signify different trajectories on sectoral and economic transition initiatives spurred using renewable energy between the Netherlands and South Africa. Policy relating to initiatives such as “agro-energy communities” in Global South countries such as South Africa should be emphasised to promote the use of renewable energy in the agricultural sector.

Quantifying the impacts of land use/land cover changes on ecosystem service values in the upper Gilgel Abbay watershed, Ethiopia Wassie Abuhay ASCHENEFE, Temesgen Gashaw TAREKEGN, Betelhem Fetene ADMAS, Solomon Mulu TAFERE Regional Sustainability    2025, 6 (1): 100197-.   DOI: 10.1016/j.regsus.2025.100197 Abstract （45）   HTML （4）    PDF （757KB）（8）       Knowledge map    Save Human well-being and livelihoods depend on natural ecosystem services (ESs). Following the increment of population, ESs have been deteriorated over time. Ultimately, land use/land cover (LULC) changes have a profound impact on the change of ecosystem. The primary goal of this study is to determine the impacts of LULC changes on ecosystem service values (ESVs) in the upper Gilgel Abbay watershed, Ethiopia. Changes in LULC types were studied using three Landsat images representing 1986, 2003, and 2021. The Landsat images were classified using a supervised image classification technique in Earth Resources Data Analysis System (ERDAS) Imagine 2014. We classified ESs in this study into four categories (including provisioning, regulating, supporting, and cultural services) based on global ES classification scheme. The adjusted ESV coefficient benefit approach was employed to measure the impacts of LULC changes on ESVs. Five LULC types were identified in this study, including cultivated land, forest, shrubland, grassland, and water body. The result revealed that the area of cultivated land accounted for 64.50%, 71.50%, and 61.50% of the total area in 1986, 2003, and 2021, respectively. The percentage of the total area covered by forest was 9.50%, 5.90%, and 14.80% in 1986, 2003, and 2021, respectively. Result revealed that the total ESV decreased from 7.42×107 to 6.44×107 USD between 1986 and 2003. This is due to the expansion of cultivated land at the expense of forest and shrubland. However, the total ESV increased from 6.44×107 to 7.76×107 USD during 2003-2021, because of the increment of forest and shrubland. The expansion of cultivated land and the reductions of forest and shrubland reduced most individual ESs during 1986-2003. Nevertheless, the increase in forest and shrubland at the expense of cultivated land enhanced many ESs during 2003-2021. Therefore, the findings suggest that appropriate land use practices should be scaled-up to sustainably maintain ESs. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Enhancing climate-smart coastal farming system through agriculture extension and advisory services towards the avenues of farm sustainability Md Maruf BILLAH, Mohammad Mahmudur RAHMAN, Santiago MAHIMAIRAJA, Alvin LAL, Asadi SRINIVASULU, Ravi NAIDU Regional Sustainability    2025, 6 (4): 100243-.   DOI: 10.1016/j.regsus.2025.100243 Abstract （45）   HTML （7）    PDF （914KB）（4）       Knowledge map    Save Agriculture extension and advisory services (AEAS) are integral to smart agricultural systems and play a pivotal role in supporting sustainable agricultural development. The study aimed to assess the role of AEAS in strengthening climate-smart coastal farming system to enhance coastal agricultural sustainability. A mixed-methods study was conducted in the southwestern coastal region of Bangladesh in 2023, which involved administering a structured questionnaire and conducing face-to-face interviews with 390 farmers. Perceived role index (PRI) was employed to assess the potential role of AEAS. To forecast the perceived role outcomes, the machine learning model was undertaken by utilizing suitable algorithms. Additionally, feature importance was calculated to underpin the significant factors of perceived role outcomes. The findings showed that coastal farming communities held a comprehensive understanding of the role of AEAS. Key roles included diffusion of agricultural innovations, acting as a bridge between farmers and research organizations, using demonstration techniques to educate farmers, training farmers on food storage, processing, and utilization, and promoting awareness and adoption of best practices. The machine learning model exposed a significant relationship between farmers’ socio-economic characteristics and their perception behavior. The results identified that factors like innovativeness, awareness, training exposure, access to AEAS, and access to information significantly influenced how farmers perceived the efficacy of AEAS in promoting a smart coastal farming system. However, farmers confronted multiple constraints in receiving demand-driven services and maintaining coastal farm sustainability. These insights can guide concerned authorities and policy-makers in providing AEAS for the purpose of strengthening climate-smart coastal farming system, particularly with a special focus on capacity building programs and machine learning application. Moreover, the outcomes of this study can assist the authorities of similar coastal systems throughout the world to initiate potential strategies for enhancing region-specific agricultural sustainability.

Unlocking climate change resilience: Socioeconomic factors shaping smallholder farmers’ perceptions and adaptation strategies in Mediterranean and Sub-Saharan Africa regions Osama AHMED, Mourad FAIZ, Laamari ABDELALI, Safwa KHOALI, Cataldo PULVENT, Sameh MOHAMED, Mame Samba MBAYE, Thomas GLAUBEN Regional Sustainability    2025, 6 (1): 100195-.   DOI: 10.1016/j.regsus.2025.100195 Abstract （44）   HTML （4）    PDF （468KB）（4）       Knowledge map    Save Climate change poses substantial challenges to agricultural productivity and sustainability, particularly in Mediterranean and Sub-Saharan Africa regions. Local smallholder farmers’ adaptation strategies to climate change are crucial for mitigating these impacts. Therefore, this study investigated the socioeconomic factors influencing smallholder farmers’ perceptions and adaptation strategies to climate change in four countries (Morocco, Egypt, Italy, and Senegal) of Mediterranean and Sub-Saharan Africa regions using a binary logistic regression (BLR) model. The results indicated that educational level, farming experience, agricultural income, farm size, participation in agricultural workshops, and training in Good Agricultural Practices (GAPs) significantly impacted smallholder farmers’ perceptions and adaptation strategies to climate change (such as smallholder farmers adopting drought-tolerant crops). Higher educational level was linked to the greater possibility of smallholder farmers adopting drought-tolerant crops in Italy and Egypt, while gaps in rural education limited the possibility of smallholder farmers adopting drought-tolerant crops in Morocco and Senegal. Farming experience and agricultural income also enhanced the possibility of smallholder farmers adopting drought-tolerant crops, with notable variations across countries due to systemic barriers such as limited infrastructure in Senegal. Larger farm size and participation in agricultural workshops further improved the possibility of smallholder farmers adopting drought-tolerant crops, particularly in Morocco and Egypt. The findings highlighted the importance of tailored interventions and policy measures to support smallholder farmers in effectively responding to the challenges of climate change under diverse agricultural contexts. By understanding the specific needs and circumstances of smallholder farmers in these countries, policymakers can develop more effective adaptation strategies to enhance agricultural resilience and sustainability under the context of climate change.

Analysis of environmental protection priority zones and their impacts on urban planning in small- and medium-sized cities of Indonesia Rizal IMANA, Andrea Emma PRAVITASARI, Didit Okta PRIBADI Regional Sustainability    2025, 6 (2): 100211-.   DOI: 10.1016/j.regsus.2025.100211 Abstract （44）   HTML （6）    PDF （2216KB）（15）       Knowledge map    Save Urbanization in small- and medium-sized cities has often been overlooked in urban studies. Research on urbanization has predominantly focused on large metropolitan cities; however, urbanization in small- and medium-sized cities also contributes to the acceleration of urban sprawl. Urban growth boundary (UGB) is an ecological approach designed to limit urban development. This study aimed to analyze environmental protection priority zones by combining ecological quality and sensitivity indices to identify the areas suitable for UGB implementation. Tegal City and its surrounding areas (including Tegal and Brebes regencies) of Indonesia were selected as the study area. The ecological quality index was calculated using the normalized difference vegetation index, humidity index, land surface temperature, and normalized difference bare soil index. These indices were subsequently subjected to principal component analysis (PCA) to extract orthogonal factors, which were summed to derive the final index value. In parallel, we mapped and evaluated ecological sensitivity based on spatial planning policies and regulations. The results revealed that ecological quality in Tegal and Brebes regencies was predominantly categorized as good and very good ecological quality, whereas Tegal City exhibited moderate and poor ecological quality. Additionally, over 45.00% of the area in Tegal and Brebes regencies demonstrated very high ecological sensitivity. Consequently, more than 50.00% of the area in Tegal and Brebes regencies, along with 27.00% of Tegal City, were classified as ecological constraint zone, making them potential regions for UGB development. The UGB is expected to curtail urban expansion, promote compact city planning, and preserve ecosystem services to achieve urban sustainability. This study implies that planning small- and medium-sized cities is important to prevent urban sprawl and maintain environmental health. Designing UGB to limit urban expansion should be enhanced by better knowledge about its ecological functions in supporting urban sustainability.

Relationship between environmental performance indices and blockchain-based sustainability-focused companies: Evidence from countries in Europe and America Hussain Mohi-ud-Din QADRI, Hassnian ALI, Atta UL MUSTAFA Regional Sustainability    2025, 6 (2): 100214-.   DOI: 10.1016/j.regsus.2025.100214 Abstract （42）   HTML （4）    PDF （952KB）（6）       Knowledge map    Save As the world grapples with increasing environmental challenges, innovative technologies are essential for promoting sustainability and accountability. This study examined the impact of environmental performance indices (EPIs) on the growth and investment trends of blockchain-based sustainability-focused companies in 15 countries (Belgium, Czechia, Denmark, Estonia, Finland, France, Germany, Italy, Norway, Poland, Sweden, Spain, Switzerland, the United Kingdom, and the United States) from Europe and America during 2010-2022. This study used the negative binomial regression model to assess the relationship between EPIs and blockchain-based sustainability-focused companies based on the data from the CrunchBase and EarthData. Results indicated that in ecosystem vitality, national terrestrial biome protection efforts were negatively correlated the formation of blockchain-based sustainability-focused companies, while global terrestrial biome protection efforts and marine protected areas had a positive impact on the formation of these companies and the number of funding rounds. In environmental health, PM2.5 exposure had a positive impact on the number of funding rounds. Conversely, pollutants such as sulfur dioxide (SO2) and ocean plastics deterred the formation of blockchain-based sustainability-focused companies and reduced the number of funding rounds. In climate change performance, adjusted emission growth rate for carbon dioxide (CO2), adjusted emission growth rate for F-gases, and adjusted emission growth rate for black carbon had a significantly positive impact on the formation of blockchain-based sustainability-focused companies. Conversely, adjusted emission growth rate for Nitrous Oxide (N2O) and projected greenhouse gas emissions in 2050 negatively affected the formation of these companies. These findings highlight the dual role of EPIs as driving factors and barriers in the development and investment of blockchain-based sustainability-focused companies in countries from Europe and America.

Would resettlement be better? Understanding how poverty alleviation resettlement influences the well-being of poverty alleviation migrants in China LIU Bingsheng, YIN Yimeng, MA Li Regional Sustainability    2025, 6 (3): 100228-.   DOI: 10.1016/j.regsus.2025.100228 Abstract （41）   HTML （3）    PDF （566KB）（4）       Knowledge map    Save Poverty remains one of the most pressing global challenges of this era, affecting millions of people across both developing and developed countries. The poverty alleviation resettlement (PAR) is a policy with Chinese characteristics for eradicating poverty. By integrating the Maslow’s Hierarchy of Needs and Amartya Sen’s Capability Approach, this study developed a theoretical framework to analyze the factors influencing the well-being of poverty alleviation migrants (PAMs). A telephone survey conducted between July and August 2022 in Hubei Province, Guizhou Province, Shaanxi Province, and Chongqing Municipality of China yielded 259 valid questionnaires. Using the partial least squares-structural equation modeling (PLS-SEM), this study revealed that financial accessibility, health level, living conditions, and social networks significantly enhanced the well-being of PAMs, with living conditions having the strongest impact on the well-being of PAMs. Furthermore, the factors affecting well-being varied across age groups. Social networks played a more significant role in the elderly group, whereas health level had a greater impact on the young and middle-aged group. These findings deepen the understanding of the PAR and its effects on the well-being of PAMs, offering valuable insights for policy-makers and practitioners to refine poverty alleviation strategies and enhance social welfare.

Impact of environmental taxes, hydroelectricity consumption, economic globalization, and gross domestic product (GDP) on the load capacity factor in the selected European Union (EU) member countries Funda KAYA, Badsha MIA, Most. Asikha AKTAR, Md. Shaddam HOSSAIN, Md Mahedi HASSAN, Muhammad Abdur RAHAMAN, Liton Chandra VOUMIK Regional Sustainability    2025, 6 (2): 100210-.   DOI: 10.1016/j.regsus.2025.100210 Abstract （41）   HTML （2）    PDF （780KB）（4）       Knowledge map    Save The intersection of economic development, energy dynamics, environmental policy, and environmental sustainability presents complex challenges for European Union (EU) countries. This study investigated the impact of environmental taxes, hydroelectricity consumption, economic globalization, and gross domestic product (GDP) on the load capacity factor (LCF) in the 10 EU member countries (including Austria, Finland, France, Germany, Italy, Poland, Portugal, Slovakia, Spain, and Sweden) using data from 1995 to 2020. To ensure the reliability and validity of the data, this study applied several advanced econometric tests, including the Pesaran and Yamagata slope heterogeneity test, Pesaran cross-sectional dependence (CSD) test, second-generation unit root test, and Westerlund cointegration test. The data showed important statistical issues such as slope heterogeneity across panels, CSD, mixed-order unit root structures, and long-run associations between variables. To address these issues, we applied an augmented mean group (AMG) model as the main regression approach, and used the pooled mean group-autoregressive distributed lag (PMG-ARDL) method to check the robustness. Specifically, the AMG results indicate that a 1.000% rise in hydroelectricity consumption results in a 0.048% rise in the LCF, while a 1.000% increase in environmental taxes leads to a 0.175% increase in the LCF. Contrary to this, a 1.000% increase in economic globalization results in a 0.370% decrease in the LCF, and a 1.000% increase in GDP leads to a 0.850% decrease in the LCF. Environmental taxes have a more beneficial impact on the environment, and GDP has the most detrimental effect. The findings provide empirical evidence on the role of environmental taxes, hydroelectricity consumption, economic globalization, and GDP in driving the LCF. Additionally, the findings provide valuable information to policy-makers, academicians, and stakeholders shaping energy and environmental policies in the 10 EU member countries.

Controlling agricultural product price volatility: An empirical analysis from Cameroon Ivette Gnitedem KEUBENG, George Achu MULUH, Vatis Christian KEMEZANG Regional Sustainability    2025, 6 (2): 100215-.   DOI: 10.1016/j.regsus.2025.100215 Abstract （36）   HTML （2）    PDF （884KB）（9）       Knowledge map    Save Motivated by a significant impact of price volatility on food security and economic stability in Cameroon, this study aims to understand the factors influencing agricultural product price volatility (APPV) and formulate effective policies for mitigating its negative impact and promoting sustainable economic growth. Specifically, this research used the autoregressive distributed lag-error correction model (ARDL-ECM) to analyse the impact of agricultural productivity, agricultural product imports, population, temperature variation, gross domestic product (GDP) per capita, and government expenditure on APPV based on the annual data from 2000 to 2021. The ARDL-ECM estimation results revealed that agricultural productivity (β=4.901), agricultural product imports (β=1.012), population (β=13.635), and GDP per capita (β=2.794) were positively related to APPV, while temperature variation (β= -0.990) and government expenditure (β= -8.585) were negatively related to APPV in the long term. However, temperature variation had a positive relationship with APPV in the short term. Moreover, the Granger causality test showed that there were bidirectional causality of APPV with agricultural productivity and agricultural product imports, and unidirectional causality of APPV with population, temperature variation, GDP per capita, and government expenditure. The findings highlight the importance of public policies in stabilizing agricultural product prices by investing in agricultural research, improving access to agricultural inputs, strengthening farmer capacities, implementing climate adaptation measures, and enhancing rural infrastructure. These policies can reduce APPV, improve food security, and promote inclusive economic growth in Cameroon. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Exploring the transformation mechanism of modern agricultural villages in the loess hilly and gully regions using actor-network theory ZHANG Tianyang, LI Linna Regional Sustainability    2025, 6 (2): 100212-.   DOI: 10.1016/j.regsus.2025.100212 Abstract （35）   HTML （6）    PDF （1286KB）（7）       Knowledge map    Save As urbanization accelerates, rural regions in China are experiencing transformative changes. This study examines the transformation mechanism of modern agricultural villages in the loess hilly and gully regions, using Zhaojiawa Village in Shannxi Province of China as a case study. In this study, we explored the village’s evolution amid China’s rural revitalization efforts, highlighting the transition from a traditional agricultural village to a modern agricultural village in the context of rapid urbanization. This study employed actor-network theory (ANT) to investigate the complex interactions among diverse actors that drive rural transformation. ANT interlinks spatial relationships with intricate social networks. We utilized Google Earth remote sensing images in 2015 and 2021 and interview data to construct ANT. Three key dimensions of rural transformation are identified: economic structure transformation, social relationship reorganization, and spatial layout reconstruction. The transformation mechanism in Zhaojiawa Village is underpinned by a network of diverse actors, both human and non-human, aligned around two pivotal stages of agricultural village development (i.e., construction stage and development stage). In the initial construction stage, the Suide County government led a complex actor network to enhance rural living and production spaces. In the development stage, the village committee emerged as a central actor, with increased participation from villagers and external enterprises, facilitating the creation of a multifunctional space. The evolving goals and roles of these key actors contributed to the reconfiguration of the actor network, promoting rural transformation. These insights are applicable to other ecologically vulnerable and economically challenged rural areas in the loess hilly and gully regions, suggesting that collaboration among stakeholders can effectively facilitate the transition to specialized and integrated industries, thereby fostering rural revitalization.

Desertification dynamics in the Tarim Basin during 1990-2020 YU Xiang, LEI Jiaqiang, GAO Xin, SUN Lingxiao, LYU Zhentao, Ireneusz MALIK, Malgorzata WISTUBA Regional Sustainability    2025, 6 (3): 100226-.   DOI: 10.1016/j.regsus.2025.100226 Abstract （35）   HTML （3）    PDF （5640KB）（13）       Knowledge map    Save Desertification poses a significant ecological threat to global sustainability, notably within arid regions such as the Tarim Basin surrounding the extensive Taklimakan Desert in Northwest China. This study used the Google Earth Engine (GEE) platform and Random Forest (RF) to analyze multi-temporal Landsat images to reveal desertification dynamics in the Tarim Basin spanning from 1990 to 2020. The results showed that land use types of the Tarim Basin were classified into three types: artificial oases, natural oases, and desertified land. To robustly quantify the spatiotemporal dynamics of land use, we introduced the Desertification Change Index (DCI), a novel metric specifically designed to measure the transformation sensitivity of land use types. Our analysis demonstrated that from 1990 to 2020, artificial oases showed a continuous increasing trend, while desertified land decreased significantly. Natural oases decreased during 1990-2000, then continued to grow, and showed a decreasing trend again after 2015. Moreover, natural oases have mainly been converted into desertified land and artificial oases. Artificial oases were mainly converted into natural oases, and most of desertified land was converted into natural oases. Regions with significant oasis expansion (DCI=2) were mostly concentrated within the influence radius of artificial oases. In contrast, regions with significant oasis degradation (DCI= -2) were generally farther from artificial oases. Finally, this study found that the changes in land use types of the Tarim Basin are mainly driven by human activities, which play a dual role—mitigating desertification by controlling oasis expansion and exacerbating desertification through unsustainable resource utilization. Ultimately, this research provides essential insights for policy-makers and land managers aiming to devise adaptive and sustainable desertification control measures in the Tarim Basin and similarly arid regions globally.

Exploring the influence of trade openness, energy consumption, natural resource rents, and human capital in achieving carbon neutrality Olani Bekele SAKILU, CHEN Haibo Regional Sustainability    2025, 6 (4): 100247-.   DOI: 10.1016/j.regsus.2025.100247 Abstract （35）   HTML （2）    PDF （1037KB）（6）       Knowledge map    Save Addressing the pressing challenges of climate change and global warming requires a strong commitment to reducing carbon dioxide (CO2) emissions and achieving carbon neutrality. Efficient energy use and international trade play crucial roles in promoting sustainable development and enhancing environmental quality. This study investigated the relationships of CO2 emissions with trade openness (export and import), energy consumption (renewable energy consumption and fossil fuel consumption), natural resource rents, and human capital across 20 developing countries (Brazil, Iran, Russia, China, Malaysia, Saudi Arabia, Colombia, Mexico, South Africa, Costa Rica, Morocco, Tunisia, Egypt, Pakistan, Türkiye, India, Peru, Viet Nam, Indonesia, and Philippines) from 1990 to 2022 using the augmented mean group (AMG) and common correlated effects mean group (CCEMG) methods. The findings revealed that export, renewable energy consumption, and human capital significantly reduce CO2 emissions, while import, fossil fuel consumption, and natural resource rents increase CO2 emissions, although the effect of natural resource rents is statistically insignificant. Causality tests indicated the bidirectional relationship of CO2 emissions with export, import, renewable energy consumption, and fossil fuel consumption, and the unidirectional causality from human capital to CO2 emissions. CO2 emissions drive the greenhouse effect, thereby raising global temperature and accelerating climate change. As reducing CO2 emissions becomes an urgent global priority, this study provides actionable insights by identifying key variables that mitigate emissions and enhance sustainability. By bridging research and policy, this study offers targeted recommendations to accelerate progress toward a low-carbon future.

Challenges and opportunities in the energy transition of agribusiness: A deep dive into the rebound effect in Latin America Fábio DE OLIVEIRA NEVES, Eduardo Gomes SALGADO, Mateus CURY, Jean Marcel Sousa LIRA, Breno Régis SANTOS Regional Sustainability    2025, 6 (3): 100225-.   DOI: 10.1016/j.regsus.2025.100225 Abstract （34）   HTML （9）    PDF （451KB）（5）       Knowledge map    Save Growing climate change concerns have intensified the focus on agribusiness sustainability, driving an urgent energy transition to improve production efficiency and mitigate environmental harm. The complex interplay between energy efficiency and energy consumption highlights the essential role of strategic energy policies in ensuring sustainable development. This study used the Double-Log regression model with bootstrap resampling to examine the rebound effect in the energy transition of agribusiness focusing on five Latin American countries including Brazil, Argentina, Uruguay, Colombia, and Mexico based on the agricultural sector data during 2010-2022. The findings revealed that the rebound effect significantly influences energy transition, with varying degrees of impact across agricultural sectors. This study identified partial rebound effect across all five countries, with elasticity coefficient varying from 9.63% (Colombia’s coffee sector) to 89.12% (Brazil’s livestock sector). In Brazil’s sugarcane sector, non-renewable energy, agricultural employment, and irrigation efficiency were identified as key factors influencing energy consumption, while in livestock sector, energy consumption was affected by CH4 emissions, income and well-being of farmers, water consumption, and water conservation practices. In Mexico’s livestock sector, CH4 emissions, non-renewable energy, and water conservation practices were the key factors affecting energy consumption. In Argentina’s sugarcane sector, pesticides, NO2 emissions, renewable energy, and agricultural employment were the key factors affecting energy consumption, while renewable energy, income and well-being of farmers, and water consumption were the key factors affecting energy consumption in livestock sector. In Uruguay’s livestock sector, non-renewable energy, income and well-being of farmers, and irrigation efficiency were the key factors affecting energy consumption. In Colombia’ coffee sector, NO2 emissions and irrigation efficiency were identified as key factors influencing energy consumption. Finally, this study reinforces the importance of aligning energy transition with Sustainable Development Goals (SDGs), ensuring that energy efficiency gains do not inadvertently increase energy consumption or environmental degradation.
