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.

人类福祉和生计依赖于自然生态系统服务。随着人口的增加，生态环境随着时间的推移而恶化。土地利用/土地覆被变化最终对生态系统的变化产生深远的影响。本研究的主要目的是确定埃塞俄比亚上Gilgel Abbay流域LULC变化对生态系统服务价值（esv）的影响。利用代表1986年、2003年和2021年的三幅Landsat图像研究了LULC类型的变化。利用地球资源数据分析系统（ERDAS） Imagine 2014中的监督图像分类技术对Landsat图像进行分类。基于全球生态服务分类体系，本文将生态服务分为供给服务、调节服务、支持服务和文化服务四大类。采用调整后的ESV系数效益法测量土地利用价值变化对ESV的影响。本研究确定了耕地、森林、灌丛、草地和水体5种土地利用资源类型。结果表明，1986年、2003年和2021年，耕地面积分别占总面积的64.50%、71.50%和61.50%。1986年、2003年和2021年森林覆盖率分别为9.50%、5.90%和14.80%。结果表明，1986 ~ 2003年，ESV总量从7.42×107下降到6.44×107美元。这是由于耕地的扩张以牺牲森林和灌木为代价。2003-2021年，由于森林和灌丛的增加，总ESV从6.44×107增加到7.76×107美元。1986-2003年期间，耕地面积的扩大和森林、灌木林地的减少使生态系统生物量减少最多。然而，在2003-2021年期间，以耕地为代价的森林和灌木的增加增加了许多ESs。因此，研究结果建议应扩大适当的土地使用方法，以可持续地维持生态环境。

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.

There is a need for more focus in understanding the economic benefits of Climate-Smart Agriculture (CSA) interventions, particularly in sub-Saharan Africa, where extreme climate events are significantly affecting agriculture and rural livelihoods. 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.

需要更加重视了解气候智慧型农业（CSA）干预措施的经济效益，特别是在极端气候事件严重影响农业和农村生计的撒哈拉以南非洲地区。本研究使用净现值（NPV）、内部收益率（IRR）、效益成本比（BCR）和投资回收期来评估加纳北部旱地农业系统中三个村（Doggoh、Jeffiri和Wulling）所采用的CSA干预措施的经济可行性，这些村大多采用CSA干预措施。通过问卷调查对161户农户进行数据收集。结果表明，农牧结合、混作、轮作、养分整合和打结垄作等CSA干预措施提高了小农的作物产量和家庭收入。小农选择的5种CSA干预措施的优先级依次为：畜粮一体化（BCR=2.87）、混作（BCR=2.54）、轮作（BCR=2.24）、养分一体化（BCR=1.98）、打垄（BCR=1.42）。结果进一步表明，即使在5.00年的较长投资回收期的悲观假设下，畜产一体化也是最有利可图的CSA干预措施。此外，本研究表明，实施CSA干预措施平均而言相对有利可图，对小农来说具有名义金融风险。了解CSA干预措施的经济可行性将有助于在决策过程中选择正确的CSA干预措施以促进恢复力的发展。

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.

可再生能源比重逐步提高。绿色氢有可能成为未来主要的能源载体之一。俄罗斯联邦与亚太地区国家，特别是中国合作，有潜力在绿色氢市场中发挥重要作用。本研究评估了在俄罗斯联邦远东联邦区（FEFD）开发基于风能的绿色氢能的潜力。经验风速数据采集自俄罗斯远东气象局4个地区（萨哈林斯克州、滨海边疆区、哈巴罗夫斯基边疆区和阿穆尔斯克州）的20个气象站。采用威布尔分布预测绿色制氢潜力。采用Justus经验法（EMJ）、Lysen经验法（EML）、极大似然法（MLE）、功率密度法（PDM）和中位数和四分位数法（MQM） 5种方法确定威布尔分布的参数（景观因子和尺度因子）。我们根据三台风力涡轮机的技术规格计算了总发电潜力：Senvion 6150陆上，H165-4.0 MW和Vestas V150-4.2 MW。结果表明，符拉迪沃斯托克、Pogibi、Ilyinskiy、yuzho - kuril’sk、Severo-Kuril’sk、Kholmsk和Okha站具有较高的绿色制氢潜力，其中符拉迪沃斯托克站使用h161 -4.0 MW风力机的绿色制氢潜力最高，可达2.56×105 kg/a。在经济分析方面，采用H165-4.0 MW风机的南千岛斯克站、伊林斯基站、波吉比站和符拉迪沃斯托克站的氢平化成本（LCOH）值分别为3.54、3.50、3.24和2.55美元/kg，均低于4.00美元/kg。本研究的结论是，FEFD在绿色氢的生产方面具有巨大的潜力，并且在适当的投资下，有可能成为亚太地区绿色氢贸易的重要枢纽。

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.

气候变化对农业生产力和可持续性构成重大挑战，特别是在地中海和撒哈拉以南非洲地区。当地小农适应气候变化的战略对于减轻这些影响至关重要。因此，本研究采用二元logistic回归（BLR）模型研究了影响地中海和撒哈拉以南非洲地区摩洛哥、埃及、意大利和塞内加尔四个国家小农对气候变化认知和适应策略的社会经济因素。结果表明，教育水平、农业经验、农业收入、农场规模、参与农业研讨会和良好农业规范（gap）培训显著影响小农对气候变化的认知和适应策略（如小农种植耐旱作物）。在意大利和埃及，较高的教育水平与小农采用耐旱作物的可能性较大有关，而在摩洛哥和塞内加尔，农村教育的差距限制了小农采用耐旱作物的可能性。农业经验和农业收入也增加了小农种植耐旱作物的可能性，由于塞内加尔基础设施有限等系统性障碍，各国之间存在显著差异。农场规模的扩大和农业车间的参与进一步提高了小农采用耐旱作物的可能性，特别是在摩洛哥和埃及。研究结果强调了有针对性的干预措施和政策措施的重要性，以支持小农在不同农业背景下有效应对气候变化的挑战。通过了解这些国家小农的具体需求和情况，政策制定者可以制定更有效的适应战略，以增强气候变化背景下的农业抵御力和可持续性。

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.</div></div>","PeriodicalId":34395,"journal":{"name":"Regional Sustainability","volume":"6 1","pages":"Article 100195"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The economic potential induced by environmental changes in the Arctic region garnered substantial interest, which positions Arctic trade as a crucial indicator in forecasting the impacts of climate change on the global economy. Nevertheless, attention devoted to the evolving dynamics of trade in the Arctic region remains scarce. In this study, we constructed export trade network in the Arctic region (including Denmark, Finland, Sweden, Norway, Iceland, the Canadian Arctic, the Russian Arctic, Alaska State of the USA, and Greenland) from 1990 to 2019 and analyzed its topology and evolutionary characteristics through complex network theory. We used a structural entropy index based on the distribution of the number of trading partners and the degree of trade concentration to assess export diversity, while we also utilized a revealed comparative advantage index to evaluate product export competitiveness using the share of trade volume of each type of product. The results indicate that the total export trade in the Arctic region increased by 53.4% during 1990–2019, with the most significant growth observed in the exports of chemical products and mineral fuels. The increasing complexity of trade network in the Arctic region resulted in the region’s export destinations no longer being concentrated on a few major countries and regions. The proportion of exports from the Arctic region to Europe decreased by 13.5%, while the proportion of exports from the Arctic region to Asia and North America increased by 6.8% and 3.1%, respectively. The Arctic region exhibited clear distinctions in the range of flows of different products, and its export trade was becoming increasingly diversified. Although differences in comparative advantages between products within individual countries or regions have narrowed, substantial gaps persist. The findings of this study can enhance the comprehensive understanding of the significance and function of Arctic trade activities within the global economy, providing a scientific basis for addressing the associated challenges and opportunities in the context of climate change.

北极地区环境变化引发的经济潜力引起了极大的兴趣，这使北极贸易成为预测气候变化对全球经济影响的关键指标。然而，对北极地区不断变化的贸易动态的关注仍然很少。本研究构建了1990 - 2019年北极地区（包括丹麦、芬兰、瑞典、挪威、冰岛、加拿大北极、俄罗斯北极、美国阿拉斯加州和格陵兰岛）出口贸易网络，并运用复杂网络理论分析了其拓扑结构和演化特征。本文采用基于贸易伙伴数量分布和贸易集中度的结构熵指数来评价出口多样性，并采用显性比较优势指数来评价产品出口竞争力，以各类产品的贸易额占比来评价产品出口竞争力。结果表明，1990年至2019年期间，北极地区的出口贸易总额增长了53.4%，其中化工产品和矿物燃料的出口增长最为显著。北极地区贸易网络日益复杂，导致该地区的出口目的地不再集中于少数几个主要国家和地区。北极地区对欧洲的出口比重下降了13.5%，对亚洲和北美的出口比重分别上升了6.8%和3.1%。北极地区在不同产品的流动范围中表现出明显的差别，其出口贸易日益多样化。虽然各个国家或地区产品之间比较优势的差异已经缩小，但巨大差距仍然存在。本研究的结果可以增强对北极贸易活动在全球经济中的意义和功能的全面理解，为应对气候变化背景下的相关挑战和机遇提供科学依据。

The tourism industry is economically very important. According to the World Travel Tourism Council, in 2019, the tourism industry accounted for a quarter of all new jobs created worldwide, 10.3% of all jobs, and 9.6×10¹² USD of the global gross domestic product. This study aimed to calculate the tourism efficiency index for different Latin American countries from 2010 to 2021 using data envelopment analysis, which analyzes the relationships between input variables (including the number of employees in the tourism industry and the number of hotel-type establishments) and output variables (including tourism expenditures in other countries and public social expenditures in recreation and culture per capita). Additionally, this study aimed to identify the countries with greater tourism development and the factors that may affect the development of the tourism industry through the stochastic frontier production function. The results of the tourism efficiency index for Central America (including Costa Rica, Dominica, El Salvador, Honduras, Mexico, and Panama) and South America (including Argentina, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, and Uruguay) exhibited different trends. However, after the global health crisis, the tourism industry recovered, showing new opportunities to promote sustainability. The results of the stochastic frontier production function demonstrated that countries with higher levels of inbound and outbound tourism, contribution of tourism to the economy, natural resources, and literacy rate exhibited more efficient tourism industry, whereas countries with higher pollution levels exhibited less efficient tourism industry. The findings of this study could allow us to formulate suitable public policies to promote tourism, maintain natural resources, and diversify these sectors with more inclusive programmes that can facilitate growth and benefit vulnerable communities.

旅游业在经济上非常重要。根据世界旅游理事会的数据，2019年，旅游业占全球新增就业岗位的四分之一，占所有就业岗位的10.3%，占全球国内生产总值的9.6×1012美元。本研究旨在利用数据包络分析方法计算2010 - 2021年拉美不同国家的旅游效率指数，该方法分析了输入变量（包括旅游业员工数量和酒店类机构数量）与输出变量（包括其他国家的旅游支出和人均娱乐文化公共社会支出）之间的关系。此外，本研究旨在通过随机前沿生产函数识别旅游业发展程度较高的国家和可能影响旅游业发展的因素。中美洲（包括哥斯达黎加、多米尼加、萨尔瓦多、洪都拉斯、墨西哥和巴拿马）和南美洲（包括阿根廷、巴西、智利、哥伦比亚、厄瓜多尔、巴拉圭、秘鲁和乌拉圭）的旅游效率指数结果呈现出不同的趋势。然而，在全球卫生危机之后，旅游业复苏，呈现出促进可持续发展的新机遇。随机前沿生产函数的结果表明，出境和入境旅游水平越高、旅游对经济、自然资源和识字率的贡献越高的国家旅游业效率越高，而污染水平越高的国家旅游业效率越低。这项研究的结果可以帮助我们制定适当的公共政策，以促进旅游业，保护自然资源，并通过更具包容性的计划使这些部门多样化，从而促进增长并使弱势社区受益。

The current linear economy assumes abundant, easily accessible, and cost-effective natural resources. However, this assumption is unsustainable, especially considering the world’s current trajectory exceeding the Earth’s ecological limits. In contrast, circular economy (CE) reduces wastes and improves resource efficiency, making them a more sustainable alternative to the dominant linear model. Biomass energy generated from agricultural leftovers, forestry wastes, and municipal trash provides a renewable substitute for fossil fuels. This reduces greenhouse gas emissions and improves energy security. Proper waste management, including trash reduction, recycling, and innovative waste-to-energy technology, reduces the burden on landfills and incineration and creates renewable energy from materials that would otherwise go to waste. Although integrating these techniques is consistent with the CE’s resource efficiency and waste minimization principles, it requires addressing environmental, technical, and socioeconomic challenges. Given the pressing global issues, transitioning to a CE and implementing sustainable environmental practices are crucial to mitigate the current waste management crisis. The aim of this study is to emphasize the viability of biomass as a source of sustainable energy, the necessity of comprehensive strategies that prioritize ecological sustainability, community involvement, and innovation to achieve a circular principle based future, and the potential obstacles to the implementation of sustainable environmental practices. This study will aid in implementing CE practices to accomplish the Sustainable Development Goals (SDGs) by reducing greenhouse gas emissions and landfill loads. Beyond environmental benefits, it can also bring economic, social, and health improvements. Furthermore, this study will assist societies in addressing global issues, such as resource scarcity, pollution, and climate change, as well as transitioning to a more sustainable and resilient future.

当前的线性经济假定有丰富的、容易获得的、具有成本效益的自然资源。然而，这种假设是不可持续的，特别是考虑到世界目前的轨迹超过了地球的生态极限。相比之下，循环经济（CE）减少了浪费，提高了资源效率，使其成为主导线性模型的更可持续的替代方案。从农业剩余物、林业废弃物和城市垃圾中产生的生物质能提供了化石燃料的可再生替代品。这减少了温室气体排放，提高了能源安全。适当的废物管理，包括减少垃圾、回收利用和创新的废物转化为能源技术，可以减轻垃圾填埋和焚烧的负担，并从原本要浪费的材料中产生可再生能源。尽管整合这些技术符合CE的资源效率和废物最小化原则，但它需要解决环境、技术和社会经济方面的挑战。鉴于迫在眉睫的全球问题，向环境行政长官转型和实施可持续的环境措施对于缓解当前的废物管理危机至关重要。本研究的目的是强调生物质作为可持续能源的可行性，优先考虑生态可持续性、社区参与和创新的综合战略的必要性，以实现基于循环原则的未来，以及实施可持续环境实践的潜在障碍。这项研究将有助于实施CE实践，通过减少温室气体排放和垃圾填埋负荷来实现可持续发展目标（sdg）。除了环境效益，它还能带来经济、社会和健康方面的改善。此外，这项研究将帮助社会解决全球性问题，如资源短缺、污染和气候变化，以及向更可持续、更有弹性的未来过渡。

Green spaces in urban and suburban areas play a significant role in helping settlements adapt to climate change. The design, quantity, quality, and location of green spaces influence their ability to provide benefits to people and enhance the quality of life. Private green spaces, if adequately managed, can enhance the environmental quality. This study, based on a questionnaire survey and the Motivation/Attitude-Driven Behaviour (MADB) model, investigated how the attitudes and behaviours of residents shape private green spaces in 12 settlements of the 4 city regions (Cluj region, Nitra region, Kecskemét region, and Győr region) in 3 Central European countries (Hungary, Slovakia, and Romania). The results showed that beautiful natural environment, abundance of green spaces, beautiful settlement and streetscape, and village atmosphere were mentioned most often, along with good quality of life, with a mention rate of over 70.00% in the four city regions. Convenience also played a significant role in the management of green spaces, showing that convenience factors (less work, less waste, and cheaper management) more important for those who live in settlements nearer to the cities. The importance of biodiversity and ecology was positively correlated with socio-economic status such as education and financial situation. However, the importance of the utility of green spaces was less prevalent among original villagers and settlers. Moreover, we found that the percentage of green spaces of settlers is slightly higher than that of original villagers. The results of factor analysis revealed that socio-economic status can influence respondents’ attitudes towards green spaces. It suggests to increase ecological awareness of residents, especially for new settlers, and promote good management techniques for green spaces. This study can improve the awareness of urban planners about the importance of green spaces in suburban areas.

城市和郊区的绿地在帮助住区适应气候变化方面发挥着重要作用。绿色空间的设计、数量、质量和位置影响着它们为人们提供福利和提高生活质量的能力。私人绿地如管理得当，可提升环境质素。本研究基于问卷调查和动机/态度-驱动行为（MADB）模型，调查了3个中欧国家（匈牙利、斯洛伐克和罗马尼亚）4个城市地区（克卢日地区、尼特拉地区、凯奇克姆·萨默斯特地区和Győr地区）的12个住区居民的态度和行为如何塑造私人绿地。结果表明：自然环境优美、绿地丰富、聚落和街景优美、乡村氛围被提及最多，生活质量好，四个城市区域提及率均超过70.00%。便利也在绿地管理中发挥了重要作用，表明便利因素（更少的工作、更少的浪费和更便宜的管理）对那些住在离城市更近的定居点的人更重要。生物多样性和生态的重要性与教育、经济等社会经济状况呈正相关。然而，绿地效用的重要性在原来的村民和定居者中并不那么普遍。此外，我们发现移民的绿地比例略高于原始村民。因子分析结果显示，社会经济地位会影响受访者对绿地的态度。建议提高居民特别是新移民的生态意识，推广良好的绿地管理技术。本研究可以提高城市规划者对郊区绿地重要性的认识。

Despite a growing body of literature on smart specialization, the role of public authorities and innovation intermediaries, particularly in developing regions, remains understudied. This research examines one of the first attempts to apply the smart specialization framework to the development of an innovation strategy outside Europe, specifically in the Pernambuco State, Brazil. We focus on two priority areas (clothing and high-tech automotive components) identified by the state government as key targets for pilot policy experimentation and use different methods, such as social network analysis and content analysis, to interview strategic innovation actors for studying the promotion of innovation and regional development in Pernambuco. Findings highlight how regional governance, collaboration, and trust are shaped by public authorities and innovation intermediaries. The study identifies three key challenges in implementing smart specialization strategy in developing regions: i.e., achieving effective decentralization, cultivating an innovation culture, and establishing participatory governance mechanisms. The public sector actors act as crucial knowledge brokers and policy intermediaries, facilitating the linkages and partnerships necessary to overcome these challenges.

尽管关于智能专业化的文献越来越多，但公共当局和创新中介机构的作用，特别是在发展中地区，仍未得到充分研究。本研究考察了将智能专业化框架应用于欧洲以外创新战略发展的首次尝试之一，特别是在巴西伯南布哥州。我们将重点放在州政府确定的两个优先领域（服装和高科技汽车零部件），作为试点政策实验的关键目标，并使用不同的方法，如社会网络分析和内容分析，采访战略创新参与者，以研究促进创新和伯南布哥州的区域发展。研究结果强调了公共当局和创新中介机构如何塑造区域治理、合作和信任。该研究确定了在发展中地区实施智能专业化战略的三个关键挑战：即实现有效的权力下放、培育创新文化和建立参与式治理机制。公共部门行为者作为关键的知识掮客和政策中介，促进克服这些挑战所必需的联系和伙伴关系。
