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.

水资源对所有生物都至关重要，应加以妥善管理，以确保人类的安全和福祉。地表水不断面临着主要由人类活动和城市化产生的严重污染风险。在尼日利亚等发展中国家，垃圾乱扔和倾倒的问题正日益影响空气和水等环境资源。几项研究表明，重金属含量超过了世界卫生组织（世卫组织）的标准，令人震惊。塑料垃圾占垃圾的很大一部分，影响水质。污染导致水生生态系统耗竭和与水有关的疾病增加。本综述旨在评估垃圾倾倒对尼日利亚地表水水质的影响。在这一审查中，汇编了关于尼日利亚地表水的各种研究结果，特别是那些受到城市化和废物处理影响的研究结果。这篇综述比较了许多物理和化学参数，如pH值、溶解氧和重金属，以及微生物特性，如总大肠菌群。在这些研究中还计算了水质指数（WQI），以确定水样是否适合人类消费。审查结果表明，尼日利亚许多水体的水质水平差别很大，有些样本达到或超过了世卫组织微生物、化学和物理特性准则。值得注意的是，重金属、浑浊度和pH值经常超过允许的限度，这表明污染来自农业和工业来源。多个地点的WQI结果显示，大多数地表水水源被列为“差”至“非常差”，这意味着它们不适合人类饮用。结果强调迫切需要立即采取行动，防止尼日利亚地表水的进一步损害和恶化。建议包括加强废物管理政策，促进回收倡议，促进利益相关者之间的合作，制定乱扔垃圾的处罚措施并实施罚款以遏制这一挑战，以及从小学开始提高教育意识。这一审查强调需要采取积极措施来保护尼日利亚的环境和地表水质量。

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。

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。

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。

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。

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。
