This study provides a comprehensive, seventy-year assessment of Uruguayan SSFs, analyzing long-term trends in landings, fishing effort, catch per unit effort (CPUE), and export dynamics across inland and coastal systems. Results show a sustained increase in SSF landings and CPUE since 2007, contrasting with a decline in industrial fisheries. Policy reforms promoting formalization, social security access, and participatory governance through co-management councils significantly contributed to these positive trends. However, economic analyses reveal concerning declines in product unit prices and export volumes, coupled with high dependence on low-value, unprocessed exports to emerging markets. Environmental degradation in freshwater systems and global climate change further threaten SSF sustainability. Key challenges include the need for improved stock assessments, stronger multi-level governance frameworks, enhanced value chain development, and adaptive management strategies to build resilience against external stressors. Strengthening domestic markets and promoting sustainable value-added products are essential to secure the future of SSFs in Uruguay. Beyond its national relevance, this case study provides insights for shaping global management strategies to strengthen SSFs, demonstrating that institutional reforms, community empowerment, and resilience-building are pivotal for sustaining fisheries in the face of escalating global challenges.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107873"},"PeriodicalIF":5.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MEV of three MECs was all medium, and showed a decreasing trend. The MEV of most provinces continued to improve, but it manifested as spatial disequilibrium. The difference among MECs increased, and hypervariable density was its main source. The distribution of the northern and southern MECs diverged, while that of the eastern MEC concentrated.

This study addressed the urgent need for a systems-level approach to port cybersecurity risk analysis by leveraging Fuzzy Cognitive Mapping (FCM) as a structured and transparent modeling technique. Through expert-driven concept modeling and a quantitative analysis of influence dynamics, the FCM framework enabled the identification of high-impact components and the visualization of systemic interdependencies across 19 critical factors grouped into four risk domains. The separate application of scenario configurations and simulation procedures allowed for an in-depth exploration of how specific threats—such as insider activity or legacy system removal—affect the cybersecurity landscape. These analyses revealed that while modernization reduces technical vulnerabilities, it can unintentionally amplify risks rooted in policy gaps, organizational fragmentation, and user behavior. The core contribution of this study lies in its methodological integration of FCM and simulations to produce a scalable, decision-oriented tool for cybersecurity risk governance in ports. Overall, this research advances a practical, systems-oriented framework for identifying, understanding, and mitigating cyber risk in maritime infrastructure, enabling more strategic and resilient cybersecurity planning.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107857"},"PeriodicalIF":4.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this increase poses environmental risks, particularly through black carbon (BC) emission, the second-largest contributor to Arctic warming. Reducing BC emissions in the 2025 Nationally Determined Contributions (NDCs) is essential for achieving carbon emission reduction goals and slowing Arctic warming. In this research, a policy analysis approach was adopted to comprehensively examine challenges and future frameworks for regulating BC emissions. First, the existing legal framework and practices for regulating BC emissions were comprehensively analyzed. Second, the key challenges posed by the fragmented regulation structure were identified, with particular attention to the unique characteristics of the Arctic region. Finally, highlighting the importance of interest coordination, suggestions for enhancing the regulation on BC emissions in the Arctic were proposed in response to the identified issues.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107865"},"PeriodicalIF":4.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the impact of different wind energy associated activities on ecosystems is crucial for developing effective management strategies that balance the benefits of offshore wind energy production with the risks to biodiversity and ecosystem functioning. The present work systematically reviews (PRISMA), critically assesses, and synthesizes in meta-analyses evidence of impacts from activities and associated pressures of offshore wind energy production. A total number of 129 scientific publications investigating the ecological impacts of offshore wind farms in the period from 2003 to 2024 were collated. Almost three-quarters (74 %) of the identified publications were focused on the northeast Atlantic, where installations are the most abundant. The introduction of novel habitat was the most frequently reported pressure associated with the presence of offshore foundations. The most common impacts were reported on seabirds and cetaceans, with high agreement in the literature of a negative impact during both the operational and installation phases. The results highlighted that only around one third of all theoretical interactions between ecosystem components and activities were addressed. The impacts from offshore activities linked to transmission cable installation and operation, as well as routine maintenance, and decommissioning in general, were least studied. This gap is especially relevant considering the prospects for already established offshore wind farms and the expected industry expansion. The visual and detailed synthesis of evidence is a valuable summary for decision-makers, practitioners, developers, industry and researchers informing the offshore wind sector.

Results reveal that the RU conflict affected the vulnerability, freight volume distribution, and operational efficiency of the global container shipping network by 34 %–54 % between March and September 2022. Between June and September, the system's adaptivity was below the annual average, compounded by deteriorating external conditions, culminating in the peak impact of the RU conflict on the shipping network. With increasing adaptivity, the container shipping network achieved a new equilibrium phase post-September 2022. Moreover, we observe significant spatial heterogeneity in the impact of system adaptivity on congestion in relevant shipping routes and ports across different phases. This paper provides a systematic framework for quantifying the adaptivity of the container shipping network during disruption events, contributing to a deeper understanding of the vulnerability dynamics of the shipping system.
