Global climate change will exacerbate the risk of natural environmental change in the originate areas where geographical indication agricultural products are produced, thereby threatening the livelihoods of local smallholder farmers. Due to the heterogeneity of household family characteristics and factors hindering livelihood resilience, there is a great challenge to scale up different interventions to enhance livelihood resilience. To achieve this goal, this paper introduces the family life cycle as a new research perspective into livelihood resilience research and provides targeted improvement strategies for farmers based on the typical obstacle types. The results show that: (1) The level of livelihood resilience of growers is generally low, with a mean value of 0.488. Among them, the buffer capacity is the strongest, followed by the learning capacity, and the self-organization capacity is the weakest. (2) Significant differences are found in livelihood resilience among different family life cycle. In the beginning stage, the farmer's resilience is the highest, with a mean value of 0.555, followed by the matured stage, the supporting stage, the aging stage, the raising stage, and the burdening stage's resilience is the lowest, with a mean value of 0.459. (3) Farmers across the family life cycle show different patterns of impediments to livelihood resilience. The obstacle types of matured stage, burdening and the supporting stage, beginning stage, aging stage, and supporting stage are “self-organization obstacle”, “buffer + self-organization obstacle”, “learning obstacle”, “buffer + learning obstacle” and “buffer + self-organization + learning obstacle”, respectively. Our findings will provide a new entry point for more targeted promotion of livelihood resilience enhancement interventions.
全球气候变化将加剧地理标志农产品产地自然环境变化的风险,从而威胁当地小农的生计。由于农户家庭特征和影响生计弹性的因素存在异质性,如何扩大不同的干预措施以增强生计弹性是一个巨大的挑战。为实现这一目标,本文将家庭生命周期作为新的研究视角引入生计弹性研究,并根据典型障碍类型为农户提供有针对性的改善策略。结果表明:(1)农户生计弹性水平普遍较低,均值为0.488;其中,缓冲能力最强,学习能力次之,自组织能力最弱。(2)不同家庭生命周期的生计弹性存在显著差异。苗期农户的回弹性最高,均值为0.555,其次是成熟期、支养期、老化期、饲养期和负重期,回弹性最低,均值为0.459。(3)农户在整个家庭生命周期中表现出不同的生计复原力障碍模式。成熟阶段、负担与支持阶段、开始阶段、老化阶段、支持阶段的障碍类型分别为“自组织障碍”、“缓冲+自组织障碍”、“学习障碍”、“缓冲+学习障碍”和“缓冲+自组织+学习障碍”。我们的研究结果将为更有针对性地促进生计恢复力增强干预措施提供新的切入点。

Developing next-generation battery technologies requires laboratory-scale experimentation, yet the environmental impacts of research activities in the early-stage (Technology Readiness Level (TRL) 3) remain largely undocumented. This study provides a life cycle assessment (LCA)-informed, process-based environmental assessment of 1 year of lithium-oxygen (Li-O2) battery development in university laboratories, where real laboratory inventory data were collected throughout cathode preparation and cell testing. A reference unit reflects the actual scale of laboratory experimentation conducted during the 1-year project, in which various cathode and electrolyte formulations were synthesized and tested to investigate material stability, electrochemical behaviour, and compatibility. Environmental impacts were assessed using the ReCiPe 2016 midpoint method. Results showed that electrochemical testing dominated the environmental impacts, accounting for 85.85 % of total impacts, while cathode preparation contributed 12.75 %. Process optimization, which focused on reducing unnecessary stirring, shortening drying durations, and consolidating testing schedules, reduced electricity demand and lowered environmental impacts by up to 17 % across all categories. These findings demonstrate that early-stage laboratory workflows can impose significant environmental burdens and that simple operational adjustments offer meaningful mitigation potential. This work highlights the importance of integrating environmental considerations into TRL3 research practices to support more sustainable pathways in early-stage battery research.
开发下一代电池技术需要实验室规模的实验,但研究活动在早期阶段(技术准备水平(TRL) 3)对环境的影响在很大程度上仍然没有记录。本研究提供了一个基于生命周期评估(LCA)的、基于过程的大学实验室锂氧(Li-O2)电池开发1年的环境评估,在阴极制备和电池测试过程中收集了真实的实验室库存数据。参考单元反映了在为期一年的项目中进行的实验室实验的实际规模,在该项目中,各种阴极和电解质配方被合成并测试,以研究材料的稳定性、电化学行为和相容性。使用ReCiPe 2016中点法评估环境影响。结果表明,电化学测试对环境的影响最大,占总影响的85.85%,阴极制备对环境的影响占12.75%。工艺优化的重点是减少不必要的搅拌,缩短干燥时间,巩固测试时间表,减少了电力需求,并将所有类别的环境影响降低了17%。这些发现表明,早期的实验室工作流程可能会造成重大的环境负担,而简单的操作调整可以提供有意义的缓解潜力。这项工作强调了将环境因素纳入TRL3研究实践的重要性,以支持早期电池研究中更可持续的途径。

The Carbon Border Adjustment Mechanism (CBAM) is one of the European Union's most ambitious climate-related trade initiatives, designed to reshape global industrial competitiveness well beyond Europe's borders. Despite its significance, empirical evidence on its economic impacts, particularly on partner countries such as Indonesia, remains limited. This study aims to address two objectives: first, to examine the potential effects of CBAM tariffs on the Gross Domestic Product (GDP) of EU trading partners; and second, to assess their implications for trade flows, sectoral adjustment, investment, and employment in Indonesia. Employing a Computable General Equilibrium (CGE) framework with the Global Trade Analysis Project Recursive Dynamic (GTAP-RD) model, the analysis provides evidence-based insights into how CBAM may reverberate through the Indonesian economy. The results show that while aggregate effects on partner countries' GDP are negligible, sectoral and distributional consequences are much more pronounced. In Indonesia, carbon-intensive industries, particularly iron and steel, face considerable adjustment pressures through declining labor demand and structural reallocation, whereas other sectors remain relatively resilient. This suggests that CBAM functions less as a macroeconomic shock than as a catalyst, exposing the vulnerability of specific industries to low-carbon trade regimes. These findings enrich ongoing policy debates by demonstrating that modest aggregate outcomes can mask substantial sectoral disruptions. For the EU, the study clarifies CBAM's external ramifications, while for Indonesia, it underscores the urgency of adaptive strategies, from technological upgrading to labor market policies, to transform potential risks into opportunities for sustainable industrial development.
碳边界调整机制(CBAM)是欧盟最雄心勃勃的气候相关贸易倡议之一,旨在重塑欧洲以外的全球工业竞争力。尽管其意义重大,但关于其经济影响的经验证据仍然有限,特别是对印度尼西亚等伙伴国的影响。本研究旨在解决两个目标:第一,检查CBAM关税对欧盟贸易伙伴国内生产总值(GDP)的潜在影响;第二,评估它们对印尼贸易流动、部门调整、投资和就业的影响。该分析采用可计算一般均衡(CGE)框架和全球贸易分析项目递归动态(GTAP-RD)模型,为CBAM如何影响印尼经济提供了基于证据的见解。结果表明,尽管对伙伴国GDP的总体影响可以忽略不计,但部门和分配后果要明显得多。在印尼,碳密集型产业,特别是钢铁行业,由于劳动力需求下降和结构再分配,面临着相当大的调整压力,而其他行业则保持相对弹性。这表明,CBAM的作用与其说是一种宏观经济冲击,不如说是一种催化剂,它暴露了特定行业对低碳贸易体制的脆弱性。这些研究结果表明,适度的总体结果可以掩盖重大的部门干扰,从而丰富了正在进行的政策辩论。对于欧盟来说,该研究阐明了CBAM的外部影响,而对于印度尼西亚来说,它强调了适应性战略的紧迫性,从技术升级到劳动力市场政策,将潜在风险转化为可持续工业发展的机遇。

Applying a novel scoring approach to assess the success of waste management CDM projects by region, size, and subtype 应用一种新的评分方法,按地区、规模和子类型评估废物管理CDM项目的成功
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-11-20 DOI: 10.1016/j.envdev.2025.101389

Greenhouse gas emission abatement is a primary objective of the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change (UNFCCC) under the Kyoto Protocol. In this study, three criteria were developed and ascribed to CDM projects under sectoral scope 13, “waste handling and disposal”: 1) project performance; 2) specific costs for issued certified emission reductions (CERs); and 3) transition status to the Paris Agreement Crediting Mechanism (PACM) or a voluntary carbon offsetting program. Using the criteria and a success threshold, an aggregate scoring system was devised to rate the overarching “success” of each individual project. Finally, the projects were grouped by geographic subregion, project subtype, and size classification to observe success rate differences.
Of 280 projects evaluated, only 114 were assessed as being successful under this model (40.7 %). Projects in “Latin America and the Caribbean” were more than 1.5 times more likely to be evaluated as successful as projects in “Southeast Asia” and “Mainland Asia”. Projects classified as “large” were 1.8 times more likely to be evaluated as successful compared to projects classified as “small”. Projects managing “manure”, “landfill power”, and “landfill flaring” were more likely to be evaluated as successful as “waste water” projects.
The evaluation also showed that amongst the chosen criteria, cost-effectiveness is the least critical criterion for the success and longevity of the CDM projects. The developed novel scoring method provides a useful tool to assess the general project performance of CDM projects and could also be applied to other sectoral scopes.
减少温室气体排放是《京都议定书》下的《联合国气候变化框架公约》(UNFCCC)清洁发展机制(CDM)的首要目标。在这项研究中,在行业范围13“废物处理和处置”下,为清洁发展机制项目制定了三个标准:1)项目绩效;2)核发经认证的减排量(CERs)的具体成本;3)向《巴黎协定》信用机制(PACM)或自愿碳抵消计划过渡。使用标准和成功阈值,设计了一个综合评分系统来评估每个单独项目的总体“成功”。最后,根据地理分区、项目子类型和规模分类对项目进行分组,观察成功率差异。在评估的280个项目中,只有114个在该模式下被评估为成功(40.7%)。“拉丁美洲和加勒比”项目获得成功评价的可能性是“东南亚”和“亚洲大陆”项目的1.5倍以上。被归类为“大型”的项目被评估为成功的可能性是被归类为“小型”项目的1.8倍。管理“粪便”、“垃圾填埋发电”和“垃圾填埋燃烧”的项目更有可能被评估为与“废水”项目一样成功。评估还表明,在选择的标准中,成本效益是清洁发展机制项目成功和寿命的最不关键的标准。所开发的新的评分方法为评估清洁发展机制项目的总体项目绩效提供了一个有用的工具,也可应用于其他部门范围。

Toward sustainable development: Environmental impact assessment challenges and opportunities in Ethiopia 迈向可持续发展:埃塞俄比亚的环境影响评估挑战与机遇
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2026-01-17 DOI: 10.1016/j.envdev.2026.101436

Environmental Impact Assessment (EIA) is a holistic and multidisciplinary process aimed at proactively identifying the potentially significant impacts of proposed project activities on the biophysical, cultural, political, and socioeconomic components of the environment, and human health. In Ethiopia, various challenges, including low governmental and community awareness, political instability, weak project planning, unsustainable natural resource utilization amidst rapid population growth, chronic poverty, and a lack of relevant scientific knowledge, contribute to significant environmental degradation. This review identifies the major opportunities, challenges, and gaps in the practical implementation of EIA by systematically analyzing governmental documents, policies, and secondary data. While Ethiopia has established a robust legislative framework for EIA, including an inclusive constitution, comprehensive environmental policies, and well-defined proclamations, critical gaps remain. These include a lack of implementing laws, inadequate enforcement, and insufficient capacity at ecological protection agencies, limited public participation, and weak political commitment. As a result, EIA often functions as a mere formality rather than a proactive tool for sustainable development, risking environmental degradation and undermining Ethiopia's developmental goals. This review recommends integrating EIA into all sectoral regulations, strengthening institutional structures, enhancing capacity building for EIA professionals, linking project financing to EIA compliance, and fostering public participation and transparency. By adopting these measures and promoting multi-sector collaboration, Ethiopia can revitalize its EIA framework and ensure effective environmental governance, advancing sustainable development and addressing future ecological challenges. Further research on EIA practices is essential for ongoing improvement in this critical area.
环境影响评估是一个全面和多学科的过程,旨在主动确定拟议项目活动对环境和人类健康的生物物理、文化、政治和社会经济组成部分的潜在重大影响。在埃塞俄比亚,各种挑战,包括政府和社区意识低下、政治不稳定、项目规划薄弱、人口快速增长中不可持续的自然资源利用、长期贫困以及缺乏相关的科学知识,都导致了严重的环境退化。本文通过对政府文件、政策和二手数据的系统分析,找出了环境影响评价在实际实施中的主要机遇、挑战和差距。虽然埃塞俄比亚已经建立了一个强有力的环境影响评估立法框架,包括包容性宪法、全面的环境政策和明确的公告,但仍然存在重大差距。这些问题包括法律实施不力、执法不力、生态保护机构能力不足、公众参与有限、政治承诺薄弱等。因此,环境影响评估往往只是一种形式,而不是可持续发展的积极工具,有可能导致环境恶化,破坏埃塞俄比亚的发展目标。本报告建议将环境影响评估纳入所有行业法规,加强制度结构,加强环境影响评估专业人员的能力建设,将项目融资与环境影响评估合规联系起来,并促进公众参与和透明度。通过采取这些措施和促进多部门合作,埃塞俄比亚可以重振其环境影响评估框架,确保有效的环境治理,促进可持续发展,应对未来的生态挑战。对环境影响评估实践的进一步研究对于持续改善这一关键领域至关重要。

Distribution patterns and environmental influences on China's cultural heritage: a climate and geographical analysis 中国文化遗产的分布格局与环境影响:气候与地理分析
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-12-26 DOI: 10.1016/j.envdev.2025.101419

This study analyzes the distribution characteristics and environmental factors affecting key cultural heritage sites in China. The results reveal that cultural heritage is widely distributed across the country, with high-density clusters in areas such as Shaanxi, Hebei, Henan, and the Yangtze River Delta, while regions like the northern Tibetan Plateau exhibit lower densities due to harsh environmental conditions. The distribution of different heritage types, including ancient buildings, ruins, and tombs, reflects regional cultural characteristics. Geographical location, climate conditions, and human activity significantly influence heritage distribution. The majority of cultural heritage is concentrated within the latitudes 25°–40° N and longitudes 105°–120° E, with higher densities found in low-altitude regions. At the national scale, contemporary socio-economic indicators such as population density and GDP show a negative association with heritage site density, reflecting modern urbanization pressures, although historically populous regions were major centers of heritage formation. On the other hand, areas with rich historical and cultural backgrounds benefit from human activity in terms of preservation. Warm and humid climates (annual temperature 10–20 °C, rainfall 500–1000 mm) contribute to better preservation of heritage, particularly for architectural and organic material-based sites. Using Gaussian mixture models and random forest analysis, nine regional heritage clusters with distinct environmental characteristics were identified. These include the Huabei Plain, characterized by high seasonal precipitation, and the Loess Plateau, with a high heritage density linked to historical and geographical factors. High-altitude areas, especially in the northwest and Tibet, exhibit a lower heritage density due to climate constraints. Temperature extremes (below −20 °C in winter and above 40 °C in summer) limit cultural heritage distribution, while moderate temperature fluctuations support greater preservation. Furthermore, climate risk assessments indicate that certain regions face significant threats to heritage due to hydrological, corrosion, and drought risks. Eastern China, particularly the lower Yangtze River, is highly vulnerable to water erosion, while the southwestern region faces high corrosion and biological degradation risks.

本研究分析了中国重点文化遗产地的分布特征及影响其分布的环境因素。结果表明,文化遗产在全国范围内分布广泛,陕西、河北、河南和长江三角洲等地区的文化遗产密度较高,而青藏高原北部等地区由于环境条件恶劣,文化遗产密度较低。古建筑、遗址、墓葬等不同遗产类型的分布体现了地域文化特色。地理位置、气候条件和人类活动对遗产分布有显著影响。大多数文化遗产集中在北纬25°-40°和东经105°-120°,在低海拔地区密度较高。在全国范围内,人口密度和GDP等当代社会经济指标与遗产地密度呈负相关,反映了现代城市化压力,尽管历史上人口稠密的地区是遗产地形成的主要中心。另一方面,具有丰富历史和文化背景的地区在保护方面受益于人类活动。温暖潮湿的气候(年温度10-20°C,降雨量500-1000毫米)有助于更好地保护遗产,特别是建筑和有机材料遗址。利用高斯混合模型和随机森林分析,确定了9个具有不同环境特征的区域遗产集群。其中华北平原季节性降水较多,黄土高原受历史地理因素影响,遗产密度较高。高海拔地区,特别是西北和西藏地区,由于气候的限制,遗产密度较低。极端温度(冬季低于- 20°C,夏季高于40°C)限制了文化遗产的分布,而适度的温度波动有助于更好地保存文化遗产。此外,气候风险评估表明,由于水文、腐蚀和干旱风险,某些地区面临严重的遗产威胁。中国东部地区,特别是长江下游地区,极易受到水侵蚀,而西南地区则面临着高度的腐蚀和生物退化风险。干旱风险在北部和西部地区突出,特别是对地下遗址的影响。研究提出了基于区域气候特征的针对性保护策略,为气候变化背景下的遗产保护提供了新的思路。

The results reveal that cultural heritage is widely distributed across the country, with high-density clusters in areas such as Shaanxi, Hebei, Henan, and the Yangtze River Delta, while regions like the northern Tibetan Plateau exhibit lower densities due to harsh environmental conditions. The distribution of different heritage types, including ancient buildings, ruins, and tombs, reflects regional cultural characteristics. Geographical location, climate conditions, and human activity significantly influence heritage distribution. The majority of cultural heritage is concentrated within the latitudes 25°–40° N and longitudes 105°–120° E, with higher densities found in low-altitude regions. At the national scale, contemporary socio-economic indicators such as population density and GDP show a negative association with heritage site density, reflecting modern urbanization pressures, although historically populous regions were major centers of heritage formation. On the other hand, areas with rich historical and cultural backgrounds benefit from human activity in terms of preservation. Warm and humid climates (annual temperature 10–20 °C, rainfall 500–1000 mm) contribute to better preservation of heritage, particularly for architectural and organic material-based sites. Using Gaussian mixture models and random forest analysis, nine regional heritage clusters with distinct environmental characteristics were identified. These include the Huabei Plain, characterized by high seasonal precipitation, and the Loess Plateau, with a high heritage density linked to historical and geographical factors. High-altitude areas, especially in the northwest and Tibet, exhibit a lower heritage density due to climate constraints. Temperature extremes (below −20 °C in winter and above 40 °C in summer) limit cultural heritage distribution, while moderate temperature fluctuations support greater preservation. Furthermore, climate risk assessments indicate that certain regions face significant threats to heritage due to hydrological, corrosion, and drought risks. Eastern China, particularly the lower Yangtze River, is highly vulnerable to water erosion, while the southwestern region faces high corrosion and biological degradation risks.

With the recycling constraints on traditional plastic bottles and environmental concerns regarding the volume of non-recycled plastic packaging, aluminum bottles and cans offer an environmentally-friendly alternative to packaging drinking water. An online stated preference discrete choice experiment is developed and administered to 462 US residents who currently consume bottled water. Consumers’ willingness to pay for recyclable aluminum water bottles and their attributes are estimated. We find that the type of bottle top is crucial, with consumers willing to pay a premium for resealable aluminum water bottles compared to plastic bottles but more for plastic bottles over aluminum cans with a non-resealable pop top. This provides insight into the potential for using recycled aluminum packaging in bottled water production to mitigate the volume of plastics in the environment. The application accounts for hypothetical bias using inferred attribute non-attendance. Findings indicate that inferred attribute non-attendance can influence attribute coefficient estimates and marginal willingness to pay. Results suggest that for sustainable alternatives to penetrate the market, product functionality, such as a resealable top, is as critical as the sustainable material itself.
由于传统塑料瓶的回收限制以及对非回收塑料包装数量的环境问题,铝瓶和铝罐提供了一种环保的替代包装饮用水。对462名目前饮用瓶装水的美国居民进行了在线陈述偏好离散选择实验。对消费者购买可回收铝水瓶及其属性的意愿进行了估计。我们发现瓶盖的类型是至关重要的,与塑料瓶相比,消费者愿意为可再密封的铝制水瓶支付更高的价格,但更愿意为塑料瓶而不是带有不可再密封瓶盖的铝罐支付更高的价格。这为在瓶装水生产中使用再生铝包装以减少环境中塑料量的潜力提供了见解。应用程序使用推断的属性不出席来解释假设的偏差。研究结果表明,推断属性不出席会影响属性系数估计和边际支付意愿。结果表明,要想让可持续替代品进入市场,产品功能,如可再密封的顶部,与可持续材料本身一样重要。

Modeling cooperation diffusion for urban water and reclaimed wastewater resources management 城市水与再生废水资源管理的合作扩散模型
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-11-30 DOI: 10.1016/j.envdev.2025.101392

The diffusion of cooperation among diverse stakeholders in large-scale systems is crucial for achieving socially optimal outcomes. This paper presents a novel framework for modeling how cooperation emerges and diffuses in the management of urban water and reclaimed wastewater resources, particularly in contexts where rivers and groundwater face significant risks from competing stakeholder interests, industrial pollution, and rapid urbanization. The first step toward sustainable management involves identifying stakeholders, their objectives, influence, and roles within the system, alongside analyzing their social network. The paper seeks to develop a cooperation diffusion model by evaluating how stakeholders influence one another's performance. To achieve this goal, the proposed approach combines social network analysis, stakeholder analysis, and social learning assessment. A physical model is used to evaluate water quality and quantity, while a multi-agent model simulates stakeholder behavior and decision-making. Using a linear threshold model (LTM), the cooperation diffusion process is structured and evaluated. The methodology is implemented in the Kan River Basin, which is located in the western region of the Tehran metropolitan area in Iran. The results indicate that promoting cooperation significantly boosts system performance by aligning stakeholder goals and enhancing social benefits. On average, the aquifer level rises by 30 %, whereas the average nitrate concentration decreases by approximately 50 %. These findings underscore the importance of fostering collaboration in the management of complex water resources systems. From a policy perspective, the results suggest that coupling technical interventions such as wastewater reuse with participatory reforms and stronger stakeholder engagement mechanisms is essential for sustainable outcomes. Moreover, empowering bridging actors and formalizing participatory forums can strengthen cooperation and foster long-term social acceptance of water governance strategies.
在大规模系统中,不同利益相关者之间的合作扩散对于实现社会最优结果至关重要。本文提出了一个新的框架,用于模拟合作如何在城市水和再生废水资源管理中产生和扩散,特别是在河流和地下水面临利益相关者利益竞争、工业污染和快速城市化的重大风险的情况下。可持续管理的第一步包括确定利益相关者、他们的目标、影响和在系统中的角色,以及分析他们的社会网络。本文试图通过评估利益相关者如何影响彼此的绩效来建立一个合作扩散模型。为了实现这一目标,本文提出的方法结合了社会网络分析、利益相关者分析和社会学习评估。物理模型用于评价水质和水量,多智能体模型用于模拟利益相关者的行为和决策。利用线性阈值模型(LTM)对合作扩散过程进行了结构化和评价。该方法在位于伊朗德黑兰大都市区西部地区的坎河流域实施。结果表明,促进合作可以通过协调利益相关者目标和提高社会效益来显著提高系统绩效。平均而言,含水层水位上升30%,而平均硝酸盐浓度下降约50%。这些发现强调了在管理复杂水资源系统方面促进合作的重要性。从政策角度来看,研究结果表明,将废水回用等技术干预措施与参与性改革和加强利益相关者参与机制相结合,对于取得可持续成果至关重要。此外,赋予桥梁行为者权力和使参与性论坛正式化可以加强合作,促进社会对水治理战略的长期接受。

Alongside implementing circular economic principles, the concept of reverse logistics supply chains (RLSCs) of demolition waste (DW) has captured the construction industry's attention. Due to the escalating risk vulnerability, risk management (RM) in RLSCs of DW has emerged as a critical requirement yet, has not been reviewed extensively. To address this knowledge gap, this study synthesises extant literature to develop a comprehensive RM framework for RLSCs of DW. This was accomplished through two objectives viz.: i) to explore the existing level of scientific development in RM for RLSCs of DW; and ii) to study how risks are managed in RLSCs of DW with the aim of identifying key risks, risk assessment procedures, existing mitigation strategies, and potential gaps that need to be addressed for resilient and efficient DW management practices. In total, 35 pertinent articles sourced from two search engines published between 2000 and 2024 were subjected to descriptive and content analysis. Most articles reviewed collected data through field measurements/sample testing and originated from developed countries. The waste reprocessing stage is the most vulnerable to various risks, including health and safety, environmental, industrial, social and regulatory risks. Effective risk mitigation strategies proposed include establishing favourable policies and incentives, enhancing awareness, improving information sharing, incorporating innovative technologies, ensuring multi-stakeholder engagement and adopting safety measures. The study significantly contributes to RM in RLSCs of DW by providing an overarching foundation via the proposed conceptual framework, which guides organisations to articulate an appropriate RM strategy.
除了实施循环经济原则外,拆迁垃圾(DW)逆向物流供应链(RLSCs)的概念也引起了建筑行业的注意。由于风险脆弱性的不断升级,风险管理(RM)已成为DW RLSCs的关键要求,但尚未得到广泛的审查。为了解决这一知识差距,本研究综合了现有文献,为DW的RLSCs开发了一个全面的RM框架。这是通过两个目标来实现的:i)探索DW的RLSCs的RM的现有科学发展水平;(二)研究如何在污水处理区域内管理风险,目的是确定关键风险、风险评估程序、现有缓解战略以及需要解决的潜在差距,以实现有弹性和有效的污水处理管理做法。总共有35篇相关文章来自2000年至2024年间发表的两个搜索引擎,进行了描述性和内容分析。大多数文章通过实地测量/样本测试收集的数据来自发达国家。废物后处理阶段最容易受到各种风险的影响,包括健康和安全、环境、工业、社会和监管风险。拟议的有效风险缓解战略包括制定有利的政策和激励措施、提高认识、改进信息共享、采用创新技术、确保多方利益攸关方参与以及采取安全措施。该研究通过提出的概念框架提供了一个总体基础,指导组织阐明适当的RM策略,从而为DW的RLSCs中的RM做出了重大贡献。

Media discourse evolution in climate change coverage: A corpus-assisted analysis 气候变化报道中的媒介话语演变:一个语料库辅助分析
IF 5.3 2区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-03-01 Epub Date: 2025-11-29 DOI: 10.1016/j.envdev.2025.101399

Media play a pivotal role in shaping public perceptions of climate change, influencing policy debates and societal responses to environmental challenges. This study investigates the evolution of climate change reporting in China, the UK, and the US from 2014 to 2023, focusing on its impact on public understanding during major global events. Employing Usage Fluctuation Analysis (UFA) and Discourse-Historical Approach (DHA), it provides a quantitative and qualitative examination of variations in the collocational patterns of “climate change”. Our findings reveal that, despite cultural and political differences, climate change reporting in the Chinese, British, and American press shows notable points of convergence, with observable shifts in discourse presentation and public engagement over time. Specifically, Chinese media emphasizes international cooperation and national climate policy, highlighting active engagement and responsibility. The UK media narrative reflects a leadership approach centered on institutional frameworks and international collaboration, while significant events such as Brexit contribute to thematic fragmentation. In contrast, US media discourse is characterized by polarization and sensitivity to political leadership, with shifts between fragmentation and renewed consensus accompanying changes in administration. These insights underscore the complex interplay between socio-political factors and media portrayal of climate change, highlighting the strategic role of media in both mirroring and shaping public discourse and policy. The implications of these findings are significant for stakeholders in environmental communication, policy formulation, and climate governance, emphasizing the need for strategic media engagement to foster a globally informed and proactive response.
媒体在塑造公众对气候变化的看法、影响政策辩论和社会对环境挑战的反应方面发挥着关键作用。本研究调查了2014年至2023年中国、英国和美国气候变化报道的演变,重点关注其在重大全球事件期间对公众理解的影响。采用用法波动分析(UFA)和话语历史方法(DHA),对“气候变化”搭配模式的变化进行了定量和定性的检查。我们的研究结果表明,尽管文化和政治上存在差异,但中国、英国和美国媒体的气候变化报道显示出显著的趋同点,随着时间的推移,话语呈现和公众参与的变化可以观察到。具体而言,中国媒体强调国际合作和国家气候政策,强调积极参与和责任。英国媒体的叙事反映了一种以制度框架和国际合作为中心的领导方式,而英国脱欧等重大事件则助长了主题碎片化。相比之下,美国媒体话语的特点是两极分化和对政治领导的敏感,伴随着政府更迭,分裂和重新达成共识之间的转变。这些见解强调了社会政治因素与媒体对气候变化的描述之间复杂的相互作用,突出了媒体在反映和塑造公共话语和政策方面的战略作用。这些研究结果对环境沟通、政策制定和气候治理的利益相关者具有重要意义,强调了战略性媒体参与的必要性,以促进全球知情和积极的应对。
