Chronic eutrophication and declining coastal livelihoods in the Baltic Sea drive the search for sustainable solutions such as regenerative ocean farming (ROF). ROF is a nature-based form of aquaculture using low-trophic species like seaweeds and bivalves that extract nutrients from enriched waters. It is framed as a response to combined environmental and socioeconomic challenges, not as a stand-alone technical concept. Despite growing interest, no comprehensive assessment of ROF readiness exists for the Baltic Sea. This study addresses this gap by examining stakeholder perceptions across five dimensions: socio-economic, techno-economic, environmental, regulatory, and social acceptance. Using a series of co-assessment workshops with stakeholders from Estonia, Latvia, Lithuania, Poland, and Germany, we identify key barriers including weak regulatory frameworks, low public awareness, limited infrastructure, and underdeveloped value chains. We also highlight enabling factors such as targeted training, policy reform, and improved monitoring. Results indicate that ROF remains in an early stage of development across all countries, with Germany showing the highest overall readiness. Technological and monitoring capabilities score highest, while socio-economic, and social acceptance and especially regulatory dimensions lag behind. The findings highlight the need for coordinated actions to build institutional capacities, streamline licensing, and foster public support to advance ROF as a sustainable solution for environmental restoration and coastal economic resilience in the Baltic Sea.

波罗的海的长期富营养化和沿海生计的下降促使人们寻求可持续的解决方案，如再生海洋养殖（ROF）。ROF是一种以自然为基础的水产养殖形式，利用海藻和双壳类等低营养物种从富含营养的水域中提取营养。它的框架是对环境和社会经济挑战的综合回应，而不是作为一个独立的技术概念。尽管人们的兴趣越来越大，但目前还没有对波罗的海的ROF准备情况进行全面评估。本研究通过从社会经济、技术经济、环境、监管和社会接受这五个方面考察利益相关者的看法，解决了这一差距。通过与爱沙尼亚、拉脱维亚、立陶宛、波兰和德国的利益相关者举行的一系列共同评估研讨会，我们确定了主要障碍，包括监管框架薄弱、公众意识低下、基础设施有限和价值链不发达。我们还强调了有针对性的培训、政策改革和改进监测等有利因素。结果表明，在所有国家，ROF仍处于发展的早期阶段，德国显示出最高的总体准备程度。技术和监测能力得分最高，而社会经济和社会接受度，特别是监管方面则落在后面。研究结果强调，需要采取协调一致的行动，建设机构能力，简化许可程序，并促进公众支持，以推动ROF成为波罗的海环境恢复和沿海经济复原力的可持续解决方案。

Coastal Tourist destinations need to adapt to climate variability and change to maintain their tourist competitiveness and attractiveness. Knowing the climatic potential of the destination's activities and managing the location's natural resources is crucial.

The last decades have seen advances in climate services for multiple fields. Despite this, there is little research on optimal days for different sea leisure-based activities around the central-western Mediterranean.

The present research explores, through a co-creation process with local agents, how the met-ocean conditions influence the activities. Capitalizing on the stakeholders’ insights, we defined the concept of “optimal day” and calculated their expected frequency for the specific activities identified by the stakeholders.

Our approach puts the ocean's hourly wind and wave data in service using the SIMAR numerical model owned by Puertos del Estado. It transforms them into structured and actionable information for Sea-Based Leisure Activities (SELAs from now onwards).

By computing the optimal days for each sea-based activity along Tarragona's shore (one of Europe's most important touristic areas), we pilot a methodology for their detection elsewhere. This information is instrumental in facilitating decision-making and defining diversification strategies for tourist activities. Moreover, we highlight the value of co-creation processes as a valuable tool in identifying adaptive measures for climate change.

沿海旅游目的地需要适应气候变率和变化，以保持其旅游竞争力和吸引力。了解目的地活动的气候潜力和管理该地区的自然资源至关重要。过去几十年，气候服务在多个领域取得了进展。尽管如此，很少有关于地中海中西部不同海上休闲活动的最佳天数的研究。本研究通过与当地代理人的共同创造过程，探讨了海洋条件如何影响活动。利用涉众的见解，我们定义了“最佳日”的概念，并计算了涉众确定的特定活动的预期频率。我们的方法是利用Puertos del Estado拥有的SIMAR数值模型，将海洋每小时的风和波数据投入使用。从现在起，它将这些数据转化为结构化和可操作的海上休闲活动（SELAs）信息。通过计算塔拉戈纳海岸（欧洲最重要的旅游区之一）每项海上活动的最佳天数，我们试点了一种方法，用于其他地方的检测。这些资料有助于促进决策和确定旅游活动的多样化战略。此外，我们强调共同创造过程作为确定气候变化适应措施的宝贵工具的价值。

The ‘triple whammy’ of threats to coasts and the ‘environment-tourism paradox’ - the DAPSI(W)R(M) unifying framework for coastal management 海岸威胁的“三重打击”和“环境-旅游悖论”——DAPSI(W)R(M)海岸管理统一框架

The coastal environment is a complex system formed by interactions between ecological structure and functioning, physico-chemical processes and socio-economic systems. An increase in competing uses and users requires a holistic approach to coastal management which considers the environmental, economic and societal impacts of all activities. If managed sustainably, the marine environment will deliver a range of ecosystem services which lead to benefits for society. The problem-structuring DAPSI(W)R(M) (pronounced dap-see-worm) framework is used to assess the causes, consequences and responses to change in a holistic way. Drivers of basic human needs require Activities which lead to Pressures, the mechanisms of State change on the natural system which then leads to Impacts (on human Welfare). Those then require Responses (as management Measures). The framework is used here to address the so-called ‘triple whammy’ affecting coasts worldwide – of increased urbanisation and industrialisation, increased use of physical and biological resources (such as energy, space, fishes, etc) and a decreased resistance and resilience to climate change (including sea-level rise, increased storminess, etc). In giving lessons for coastal management worldwide, this risk assessment and management framework is applied to the Balneário Camboriú – SC (Brazil) coastline which shows most of the features of coastlines worldwide and which is a major development area for Brazil. It particularly shows what may be called the ‘environment-tourism paradox’ whereby excessive coastal tourism eventually damages the desirable features initially responsible for the tourism and creates tensions between tourists and local inhabitants as seen in tourism hotspots worldwide.

沿海环境是生态结构与功能、物理化学过程和社会经济系统相互作用形成的复杂系统。竞争用途和用户的增加要求对沿海管理采取综合办法，考虑到所有活动的环境、经济和社会影响。如果以可持续方式管理，海洋环境将提供一系列生态系统服务，从而造福社会。问题结构DAPSI(W)R(M)（发音为dap-see-worm）框架用于以整体方式评估变化的原因，后果和响应。人类基本需求的驱动力需要导致压力的活动，国家改变自然系统的机制，然后导致影响（对人类福利）。然后需要响应（作为管理措施）。该框架用于解决影响全球海岸的所谓“三重打击”——城市化和工业化程度的提高，物理和生物资源（如能源、空间、鱼类等）的使用增加，以及对气候变化的抵抗力和复原力的下降（包括海平面上升、暴风雨增加等）。在为全世界沿海管理提供经验教训时，这一风险评估和管理框架适用于Balneário Camboriú - SC（巴西）海岸线，它显示了全世界海岸线的大多数特征，是巴西的一个主要发展地区。它特别显示了所谓的“环境旅游悖论”，即过度的沿海旅游最终破坏了最初负责旅游的理想特征，并造成了游客和当地居民之间的紧张关系，正如在世界各地的旅游热点所看到的那样。

The article addresses the practical application of the Ecosystem Approach to Fisheries Management (EAFM) as a strategy to promote sustainability of small-scale fisheries and the socioeconomic development of fishing communities in the state of Espírito Santo, Brazil. The primary objective was to diagnose the current status of small-scale fisheries and propose an operational plan to strengthen participatory and sustainable governance. A qualitative research design based on action research was employed, utilizing participatory workshops conducted between 2019 and 2024 with stakeholders of 14 fishing communities to identify and categorize challenges across the EAFM three main components: good governance, human well-being, and ecological well-being. Results indicated the inadequacy of institutional structures, low investment in scientific research and extension, socioeconomic vulnerabilities exacerbated by environmental disasters, and a lack of effective community participation in decisions regarding fisheries resource use. To address these challenges, a set of corrective actions are proposed to support sustainable fisheries management through participatory governance. As a practical outcome, EAFM principles were incorporated into a normative act aimed at establishing a state-level fisheries public policy, demonstrating the integration of scientific and empirical knowledge into governance and marking a significant milestone. It was concluded that the EAFM constitutes an innovative framework for practical application at the state level, offering a replicable model for decision-making and sustainable fisheries management. Despite the article's contribution to embedding EAFM within state fisheries policy, political and institutional commitment to enable its implementation remains a challenge to achieving the structural changes necessary for effective and sustainable fisheries governance.

本文讨论了渔业管理生态系统方法（EAFM）的实际应用，作为促进小规模渔业可持续性和巴西圣Espírito州渔业社区社会经济发展的战略。主要目标是诊断小规模渔业的现状，并提出一项业务计划，以加强参与性和可持续的管理。采用了基于行动研究的定性研究设计，利用2019年至2024年与14个渔业社区的利益相关者举行的参与性研讨会，确定并分类了EAFM的三个主要组成部分：善治、人类福祉和生态福祉。结果表明：制度结构不足，科研和推广投入不足，环境灾害加剧了社会经济脆弱性，社区对渔业资源利用决策缺乏有效参与。为了应对这些挑战，提出了一系列纠正行动，通过参与式治理支持可持续渔业管理。作为一项实际成果，EAFM原则被纳入一项旨在建立国家级渔业公共政策的规范性法案，这表明将科学和经验知识纳入治理，并标志着一个重要的里程碑。结论是，EAFM是国家一级实际应用的创新框架，为决策和可持续渔业管理提供了可复制的模式。尽管本文对将EAFM纳入国家渔业政策做出了贡献，但要实现有效和可持续渔业治理所必需的结构变革，政治和制度上的承诺仍然是一个挑战。

High-energy dissipative coasts deliver essential ecosystem services for people and nature, including recreation, shoreline protection, and habitat provision. Yet, coasts are highly vulnerable to sea-level rise, storm surges, and intensifying human pressures. Addressing these challenges requires nature-based solutions (NbS) integrated with supportive coastal governance. This case study presents the Changle Airport Beach (Fujian Province, Southeast China) as a policy-driven case of ecological restoration on a high-energy coast. We examine the enabling role of national and provincial marine spatial-planning policies, including Marine Function Zoning, the Marine Ecological Red Line, and Coastal Beach Resources Protection Planning, in supporting restoration and shaping management priorities. Field implementation applied hybrid measures, including beach litter remediation, large-scale beach nourishment, and backshore vegetation replenishment, to enhance morphological stability, biodiversity, and coastal defense. One year of post-restoration monitoring showed rapid gains in beach width, dune stabilisation, vegetation cover, and habitat value, confirming the effectiveness of nature-based solutions in restoring coastal ecosystem functions. The case from China illustrates how policy-driven ecological restoration, aligned with site-specific design, can deliver significant short-term ecological gains and inform long-term Integrated Coastal Zone Management (ICZM). Our findings represent one of the first comprehensive accounts of hybrid nature-based solutions implemented on a high-energy beach. They contribute to the expanding global body of evidence suggesting that the integration of marine spatial planning with nature-based restoration may offer a viable pathway to enhance coastal resilience in the face of climate change.

高能耗散海岸为人类和自然提供重要的生态系统服务，包括休闲娱乐、海岸线保护和栖息地提供。然而，海岸极易受到海平面上升、风暴潮和不断加剧的人类压力的影响。应对这些挑战需要基于自然的解决方案（NbS）与支持性沿海治理相结合。本案例研究将长乐机场海滩（中国东南部福建省）作为一个政策驱动的高能海岸生态恢复案例。我们研究了国家和省级海洋空间规划政策，包括海洋功能区划、海洋生态红线和海岸海滩资源保护规划，在支持恢复和形成管理重点方面的推动作用。现场实施采用沙滩垃圾修复、大规模海滩营养和后岸植被补充等混合措施，增强形态稳定性、生物多样性和海防能力。修复后一年的监测显示，在海滩宽度、沙丘稳定性、植被覆盖和栖息地价值方面取得了快速进展，证实了以自然为基础的解决方案在恢复沿海生态系统功能方面的有效性。中国的案例表明，政策驱动的生态恢复与具体场地设计相结合，可以带来显著的短期生态效益，并为长期的沿海地区综合管理（ICZM）提供信息。我们的研究结果代表了在高能海滩上实施的基于自然的混合解决方案的第一个全面描述之一。它们为不断扩大的全球证据体系做出了贡献，这些证据表明，将海洋空间规划与基于自然的恢复结合起来，可能为增强沿海地区应对气候变化的韧性提供一条可行的途径。

Assessing mangrove health is critical for ecosystem protection. However, prevailing Mangrove Health Index (MHI) methods often rely on subjective variable selection and weighting based on observational data, which limits their objectivity and cross-regional applicability. To overcome these issues, this study introduces a novel assessment framework that integrates a knowledge graph (KG) with link analysis. The KG was constructed by extracting causal relationships from extensive literature, thereby identifying 24 key biotic, abiotic, and socio-economic indicators. Link analysis was then applied to quantitatively determine indicator weights, assigning greater importance to variables with higher systemic influence. We validated the framework’s practicality and sensitivity through integrated field surveys and Normalized Difference Vegetation Index (NDVI) analysis at three sites with varying disturbance levels in China’s Beibu Gulf. The results showed that the derived MHI scores accurately reflected the disturbance gradient and correlated strongly with NDVI, which decreased with increasing disturbance. Our MHI framework enhances cross-regional comparability and serves as a transferable tool for global mangrove and natural resource assessments.

Synopsis: The knowledge-driven environmental assessment method establishes a robust scientific foundation for designing adaptive ecological restoration protocols and context-aware compensation mechanisms.

评估红树林的健康状况对保护生态系统至关重要。然而，目前流行的红树林健康指数（MHI）方法往往依赖于基于观测数据的主观变量选择和加权，这限制了其客观性和跨区域适用性。为了克服这些问题，本研究引入了一种新的评估框架，该框架将知识图（KG）与链接分析相结合。KG是通过从大量文献中提取因果关系来构建的，从而确定了24个关键的生物、非生物和社会经济指标。然后应用关联分析定量确定指标权重，赋予具有较高系统影响的变量更大的重要性。通过对中国北部湾3个不同干扰程度站点的综合野外调查和归一化植被指数（NDVI）分析，验证了该框架的实用性和敏感性。结果表明，所得的MHI分数准确反映了扰动梯度，且与NDVI有较强的相关性，NDVI随扰动的增大而减小。我们的MHI框架增强了跨区域的可比性，并可作为全球红树林和自然资源评估的可转让工具。摘要：知识驱动的环境评价方法为设计适应性生态恢复方案和情境感知补偿机制奠定了坚实的科学基础。

Our MHI framework enhances cross-regional comparability and serves as a transferable tool for global mangrove and natural resource assessments.</div><div>Synopsis: The knowledge-driven environmental assessment method establishes a robust scientific foundation for designing adaptive ecological restoration protocols and context-aware compensation mechanisms.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"273 ","pages":"Article 108034"},"PeriodicalIF":5.4,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685462","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}

Rip currents are one of the most hazardous natural phenomena affecting beachgoers worldwide and pose a persistent challenge to coastal safety management. This study provides a comprehensive bibliometric analysis of research into rip current detection conducted between 2006 and 2025. Significant methodological developments are highlighted, including the use of Lagrangian drifters, RPAS (Remotely Piloted Air Systems), fixed cameras, numerical models, and dye tracing. Beyond technical evaluation, the paper critically examines how these detection methods can inform and enhance coastal management practices. The operational suitability of each method is assessed in terms of daily monitoring, early warning systems, beach zoning and contexts with limited resources. The analysis emphasizes the role of rip current detection in supporting marine spatial planning, beach carrying capacity regulations, infrastructure siting, public education campaigns and real-time risk communication tools. Furthermore, the study explores how rip detection data could be incorporated into national coastal governance frameworks, in line with the Sendai Framework for Disaster Risk Reduction and Sustainable Development Goals 13 and 14. The main aim of this study is to systematically review field-based and field-validated methods for the detection and characterization of rip currents, and to critically assess their potential for operational integration into coastal safety and governance frameworks. A proposed operational integration framework outlines how the relevant authorities can tier, standardize, and adopt detection technologies to improve coastal risk governance. This work bridges the gap between technical research and actionable policy by offering evidence-based guidance for the sustainable and resilient management of coastal safety.

Conducting a comprehensive risk assessment for Harmful Algal Blooms (HABs) is a critical step toward effective management and the sustainability of coastal economies. This study establishes a novel risk assessment framework for red tide disasters in China by integrating long-term hazard patterns with coastal vulnerability. We compiled a 90-year dataset (1933–2023) of red tide events in China's coastal waters and developed a multi-dimensional hazard index based on the frequency, scale, duration, and causative species diversity of blooms. Regional vulnerability was evaluated using indicators of mariculture intensity, tourism revenue, and proximity to nuclear power plants. Our analysis reveals a predominance of dinoflagellate-related events (47.72 %) over those caused by diatoms (22.77 %). Since around 2000, the proliferation of toxic blooms has significantly increased the hazard level in the East China Sea, with a notable southward expansion in recent decades. Overall, high-risk areas were identified in the Bohai Sea, the North Yellow Sea, and the East China Sea. We discussed the combined impact of terrestrial nutrient influx and mariculture on HAB dynamics and proposed that dual-nutrient reduction strategy is crucial for mitigation. This study provides a scalable methodology and critical insights for targeted red tide management and policy-making.

对有害藻华（HABs）进行全面的风险评估是实现有效管理和沿海经济可持续发展的关键一步。本研究通过将长期灾害模式与沿海脆弱性相结合，建立了一个新的赤潮灾害风险评估框架。本文收集了中国沿海90年（1933-2023）赤潮事件数据，并基于赤潮发生的频率、规模、持续时间和导致赤潮的物种多样性，建立了一个多维度的赤潮危害指数。利用海水养殖强度、旅游收入和靠近核电站等指标对区域脆弱性进行了评估。我们的分析显示，甲藻相关事件（47.72%）高于硅藻引起的事件（22.77%）。自2000年左右以来，有毒藻华的扩散显著提高了东海的危害水平，并在近几十年向南扩展。总体而言，确定了渤海、北黄海和东海的高风险区域。我们讨论了陆地养分流入和海水养殖对赤潮动态的综合影响，并提出了双养分减少策略对减缓赤潮至关重要。本研究为有针对性的红潮管理和决策提供了可扩展的方法和重要的见解。

Evaluating navigational risks in sea ice conditions plays a crucial role in supporting safe ice navigation. This study develops a novel method for assessing navigation risks under sea ice conditions by combining sea ice hazard, vessel navigation exposure, and vulnerability curves, enabling the quantitative evaluation of pixel-based navigation risks across different sea ice conditions in the Bohai Sea. The analysis reveals that sea ice hazards under 5-year, 10-year, and 20-year return periods, derived from MODIS satellite data during 2001–2023, display a consistent spatial pattern with hazard levels gradually decreasing from nearshore to offshore areas. High-exposure zones for vessel navigation, based on AIS data, are primarily concentrated around major ports and their entrance channels. Cargo vessels, which exhibit the strongest ice resilience, are the least affected by sea ice, followed by tankers, other vessels, and tugs. Vulnerability curves for the four vessel categories—cargo, tanker, tug, and other vessels—developed using AIS data and satellite-retrieved annual maximum sea ice thickness, follow natural logarithmic functions and all pass statistical significance tests (p < 0.01). The vulnerability order generally aligns with vessel size: cargo > tanker > other vessels > tug. Based on the hazard–exposure–vulnerability framework, the pixel-based navigation risk map indicates that high-risk zones cluster around key port areas and their entrance channels. Cargo vessels exhibit the highest navigation risk, followed by tankers, tugs, and other vessels. These findings offer valuable support for policymakers in mitigating navigation risks under sea ice conditions.

海冰条件下的航行风险评估对保障海冰航行安全起着至关重要的作用。本研究提出了一种结合海冰危害、船舶航行暴露和脆弱性曲线的海冰条件下航行风险评估新方法，实现了渤海不同海冰条件下基于像素的航行风险定量评估。结果表明，2001-2023年MODIS卫星数据的5年、10年和20年回归期海冰灾害呈现出由近岸向近海逐渐降低的空间格局。根据AIS数据，船舶航行的高暴露区主要集中在主要港口及其入口航道周围。货船表现出最强的抗冰能力，受海冰影响最小，其次是油轮、其他船只和拖船。利用AIS数据和卫星获取的年最大海冰厚度，绘制了四类船舶（货船、油轮、拖船和其他船舶）的脆弱性曲线，遵循自然对数函数，并通过了统计显著性检验（p < 0.01）。易损性顺序通常与船舶尺寸一致：货物>；油轮>；其他船舶>；拖船。基于风险暴露脆弱性框架，基于像素的导航风险图表明，高危区域集中在重点港区及其入口通道周围。货船的航行风险最高，其次是油轮、拖船和其他船只。这些发现为决策者在海冰条件下降低航行风险提供了宝贵的支持。
