Environmental DNA (eDNA) metabarcoding is a method that extracts species information from environmental samples, thereby aiding in the establishment or enhancement of biodiversity assessments. This study employed eDNA and Underwater Visual Census (UVC) to obtain baseline data on the biodiversity of Mischief Reef, explore the efficacy of eDNA in detecting functional organisms, and shed light on alterations in community structure and their contributing factors. Initially, we detected organisms at nine stations with eDNA and UVC in spring, detected 178 fish and macroinvertebrates (crustacean and mollusca) species by eDNA, 151 species by UVC, respectively. The One-way analysis of variance results showed that eDNA method was superior to UVC method in detecting phylum, class, order, family, genus, and species (p < 0.01). The functional space of eDNA organisms encompassed that of UVC organisms. Significant positive correlations were found between eDNA and attributes such as activity period, diet, mean trophic level (TL), maximum body length range, and fishing vulnerability. No correlations were observed between UVC and functional attributes of organisms. The taxonomic diversity, phylogenetic diversity, and functional diversity monitored by eDNA were all significantly higher than those monitored by UVC. The interaction between the biodiversity monitored by eDNA and the environment was more significant than that monitored by UVC. Our study underscores the effectiveness of eDNA in identifying functional organisms in coral reefs and in reflecting differences in ecosystem community structure.

环境DNA元条形码是一种从环境样本中提取物种信息，从而帮助建立或加强生物多样性评价的方法。本研究利用eDNA和水下视觉普查（UVC）技术获取美济礁生物多样性基线数据，探讨eDNA检测功能生物的功效，揭示群落结构变化及其影响因素。首先，我们在春季用eDNA和UVC检测了9个站点的生物，eDNA和UVC分别检测了178种鱼类和151种大型无脊椎动物（甲壳类和软体动物）。单因素方差分析结果显示，eDNA法在门、纲、目、科、属、种检测上优于UVC法（p < 0.01）。eDNA生物的功能空间包含了UVC生物的功能空间。eDNA与活动期、饮食、平均营养水平（TL）、最大体长范围和捕捞脆弱性等属性呈显著正相关。UVC与生物体的功能属性之间没有相关性。eDNA监测的植物分类多样性、系统发育多样性和功能多样性均显著高于UVC监测的植物。eDNA监测的生物多样性与环境的交互作用比UVC监测的更显著。我们的研究强调了eDNA在识别珊瑚礁功能生物和反映生态系统群落结构差异方面的有效性。

Macroalgae are dominant primary producers in coastal ecosystems and play a critical role in ecosystem functioning and management. While microplastics (MPs) have been widely reported in marine fauna, their accumulation in macroalgae and the implications for coastal management remain underexplored. This study investigated MPs pollution in two green (Ulva intestinalis and Cladophora glomerata) and one red (Laurencia caspica) macroalgae along the Caspian Sea shorelines. We aimed to evaluate how algal structure and morphology influence MPs accumulation, and to demonstrate the potential of green and red macroalgae as natural biofilters that can trap and remove MPs, offering a sustainable tool for coastal pollution management. Macroalgae were sampled from six stations between June and August 2023. MPs were found in all macroalgae with an average of 0.34 ± 0.04, 0.13 ± 0.01, and 0.10 ± 0.04 items/g for C. glomerata, U. intestinalis and L. caspica, respectively. The predominant MPs were 300–1000 μm in size, red in color, fiber in shape and polyamide in polymer. C. glomerata exhibited significantly higher MP levels (p < 0.05), likely due to its dense and complex morphology, indicating a superior capacity for MPs uptake and retention. These findings identify macroalgae, particularly C. glomerata, as effective natural filters of MPs, with direct relevance for coastal ecosystem health. Recognizing and harnessing this biofiltration capacity can inform innovative, low-cost, and sustainable management strategies to mitigate MPs pollution and enhance coastal environmental quality.

大型藻类是沿海生态系统中主要的初级生产者，在生态系统功能和管理中起着至关重要的作用。虽然微塑料（MPs）在海洋动物群中被广泛报道，但它们在大型藻类中的积累及其对沿海管理的影响仍未得到充分研究。本研究调查了里海沿岸两种绿藻（Ulva肠子藻和Cladophora glomerata）和一种红藻（Laurencia caspica）的MPs污染情况。我们旨在评估藻类的结构和形态如何影响MPs的积累，并证明绿色和红色巨藻作为天然生物过滤器的潜力，可以捕获和去除MPs，为沿海污染管理提供可持续的工具。在2023年6月至8月期间，从六个站点采集了大型藻类样本。所有大型藻类中MPs的平均含量分别为0.34±0.04、0.13±0.01和0.10±0.04项/g。主要的MPs为300-1000 μm，颜色为红色，形状为纤维，聚合物为聚酰胺。C. glomerata表现出明显较高的MP水平（p < 0.05），这可能是由于其致密和复杂的形态，表明其具有更强的MP吸收和保留能力。这些发现确定了大型藻类，特别是C. glomerata，是MPs的有效天然过滤器，与沿海生态系统健康直接相关。认识和利用这种生物过滤能力可以为创新、低成本和可持续的管理策略提供信息，以减轻MPs污染并提高沿海环境质量。

Strengthened collaboration across different levels of governance can lead to improved marine and coastal management outcomes. For example, collaborative governance can improve coordination between institutions and communities, enhance trust to facilitate the participation of diverse actors, and build capacity for shared decision-making among both state and non-state sectors. While interest in collaborative governance for marine and coastal systems is growing, critical gaps in the scholarship remain, particularly regarding its implementation and success. Systematically identifying these knowledge gaps is essential to guide future research efforts and funding investments. To address this, we systematically reviewed empirical case studies, examining the roles of actors, the barriers and opportunities to collaboration, and the outcomes reported. We applied qualitative thematic analysis to identify key themes across the studies. A total of 4196 articles were retrieved from literature databases, and after a multi-stage screening process, 60 articles qualified for inclusion in the systematic review. We find that while collaborative governance involves a diversity of actors in marine and coastal settings, power remains unevenly distributed, often concentrated within the state. Our findings further highlight that essential conditions for supporting and sustaining collaborative governance include power sharing, legitimacy, engagement with bridging actors, and access to financial resources. Finally, we emphasise the need for standardised approaches to evaluating both social and ecological outcomes. This review contributes a roadmap for advancing collaborative governance research in marine and coastal contexts and offers recommendations to better align theory with practice.

加强不同级别治理之间的协作可改善海洋和沿海管理成果。例如，协作治理可以改善机构和社区之间的协调，增强信任以促进不同行为者的参与，并在国家和非国家部门之间建立共同决策的能力。虽然人们对海洋和沿海系统协作治理的兴趣日益浓厚，但在学术研究方面仍然存在重大差距，特别是在其实施和成功方面。系统地确定这些知识差距对于指导未来的研究工作和资金投资至关重要。为了解决这个问题，我们系统地回顾了实证案例研究，检查了参与者的角色、合作的障碍和机会，以及报告的结果。我们应用定性专题分析来确定研究中的关键主题。从文献数据库中共检索到4196篇文章，经过多阶段筛选，有60篇文章符合纳入系统评价的条件。我们发现，虽然协作治理涉及海洋和沿海环境中的各种行动者，但权力仍然分布不均，往往集中在国家内部。我们的研究结果进一步强调，支持和维持协作治理的必要条件包括权力分享、合法性、与桥梁行为者的接触以及获得财政资源。最后，我们强调需要标准化的方法来评估社会和生态结果。本综述为推进海洋和沿海环境下的协同治理研究提供了路线图，并提出了更好地将理论与实践结合起来的建议。

Understanding the resilience of coupled socio–ecological systems (SES) is critical for addressing the escalating risks faced by coastal regions under climate change. This study develops and applies a Socio–Ecological Resilience Index (SERI) framework, integrating 61 socio-economic, ecological, climatic, hydrological, geological, and maritime indicators into a multi-layered composite index. Unlike prior approaches that assessed social or ecological resilience in isolation, our framework captures their bidirectional interactions, producing a spatially explicit and transferable tool. Application to the Persian Gulf (PG) and Gulf of Oman (GO), a geostrategic but underexamined region exposed to 11 major hazards, reveals clear disparities: PG counties show consistently higher resilience (mean SERI = 0.551) compared to GO counties (mean SERI = 0.475). Notably, 94 % of Bandar Abbas's area falls into the low-resilience class, contrasting with the high resilience of Parsian and Bandar Lengeh. These results highlight a critical knowledge gap in existing frameworks, which often neglect the coupled socio-ecological dynamics shaping vulnerability under compound hazards. By advancing an integrated methodology and demonstrating its utility in a data-scarce but high-risk setting, the study offers both methodological innovation and empirical novelty. The findings provide actionable insights for evidence-based coastal management, including targeted interventions in vulnerable counties, ecological restoration, and adaptive, transboundary governance to reduce resilience disparities across coastal systems.

了解耦合社会生态系统（SES）的恢复能力对于应对气候变化下沿海地区面临的不断升级的风险至关重要。本研究开发并应用了社会生态恢复力指数（SERI）框架，将61个社会经济、生态、气候、水文、地质和海洋指标整合成一个多层复合指数。与之前孤立评估社会或生态弹性的方法不同，我们的框架捕捉了它们的双向相互作用，产生了一个空间明确且可转移的工具。波斯湾（PG）和阿曼湾（GO）是一个地缘战略但未得到充分研究的地区，面临11种主要灾害，对这两个地区的应用显示出明显的差异：PG县的恢复能力（平均SERI = 0.551）始终高于GO县（平均SERI = 0.475）。值得注意的是，阿巴斯港94%的地区属于低弹性类别，与巴黎和伦格港的高弹性形成鲜明对比。这些结果突出了现有框架中一个关键的知识缺口，这些框架往往忽视了在复合灾害下形成脆弱性的耦合社会生态动态。通过推进一种综合方法，并证明其在数据稀缺但高风险环境中的效用，该研究提供了方法创新和经验新颖性。研究结果为基于证据的沿海管理提供了可行的见解，包括对脆弱县进行有针对性的干预、生态恢复和适应性跨界治理，以减少沿海系统之间的弹性差异。

This study presents the findings of a large-scale household survey conducted across 25 fishing communities in Cameroon, which aims to assess the activities of the fishery sector and their role in enhancing livelihood sustainability. A total of 511 artisanal fishermen and fish farmers were surveyed across eight regions using structured questionnaires and field interviews. The study explores multiple dimensions of sustainability, including food security, health performance, household resilience to shocks, and environmental sustainability. Findings reveal that 56.2 % of households are food secure, while 43.8 % experience varying levels of food insecurity. The CMP ordered probit regression findings further reveal that fishery activities enhance their food security status and health performance. In terms of health, over 33 % of households reported poor or uncomfortable health conditions, with 16 % indicating excellent health. The average household income from fishery sales is notably higher among marine fishermen, with annual revenues exceeding 7 million FCFA for about 38 % of respondents. Despite this economic contribution, only 9 % of households are members of fishery cooperatives, and fewer than half have received any formal training, highlighting significant gaps in social and human capital. Furthermore, 56 % of respondents report witnessing a decline in fish species, signalling environmental degradation and unsustainable fishing practices. The report also identifies substantial participation of immigrants and internally displaced persons in the sector, making it a key livelihood option in the context of regional conflict and food insecurity. Overall, the study provides empirical insights that are critical for policy formulation aimed at improving sustainable fisheries management, enhancing rural livelihoods, and supporting vulnerable populations. The findings have broader relevance for developing countries with similar socio-ecological contexts.

本研究介绍了在喀麦隆25个渔业社区进行的大规模家庭调查的结果，该调查旨在评估渔业部门的活动及其在提高生计可持续性方面的作用。通过结构化问卷和实地访谈对八个地区的511名手工渔民和养鱼户进行了调查。该研究探讨了可持续性的多个维度，包括粮食安全、卫生绩效、家庭抵御冲击的能力和环境可持续性。调查结果显示，56.2%的家庭粮食安全，43.8%的家庭经历不同程度的粮食不安全。CMP有序probit回归结果进一步表明，渔业活动提高了其粮食安全状况和卫生绩效。在健康方面，超过33%的家庭报告健康状况不佳或不舒服，16%的家庭报告健康状况良好。海洋渔民从渔业销售中获得的平均家庭收入明显较高，约38%的受访者年收入超过700万越南法郎。尽管有这些经济贡献，但只有9%的家庭是渔业合作社的成员，而且只有不到一半的家庭接受过任何正式培训，这凸显了社会和人力资本方面的巨大差距。此外，56%的答复者报告看到鱼类种类减少，这表明环境退化和不可持续的捕捞做法。该报告还指出，移民和国内流离失所者大量参与该部门，使其成为区域冲突和粮食不安全背景下的关键生计选择。总体而言，该研究提供了实证见解，对制定旨在改善可持续渔业管理、改善农村生计和支持弱势群体的政策至关重要。这些发现对具有类似社会生态背景的发展中国家具有更广泛的相关性。

The protection of habitats for endangered waterbirds is a crucial issue for maintaining the balance of wetland ecosystems. However, ongoing climate change and land use transformations are placing increasing pressure on their habitats, making it essential to predict future shifts in suitable areas to inform effective conservation strategies. This study selected a key waterbird stopover area in China along the East Asian-Australasian Flyway (EAAF) as the research site. By integrating the Future Land Use Simulation (FLUS) model with the maximum entropy (MaxEnt) model, we simulated habitat shifts of six endangered waterbirds under various scenarios and assessed the conservation gaps in existing nature reserves. Our research shows that urban expansion and wetland reduction decrease the habitats of waterbirds and produce compound effects with climatic conditions. Three endangered waterbirds are projected to experience substantial expansions in medium- and high-suitability areas across multiple scenarios. Mean diurnal range, land use, and precipitation seasonality have the greatest impact on predictions across all species.

保护濒危水鸟栖息地是维护湿地生态系统平衡的关键问题。然而，持续的气候变化和土地利用的转变正在给它们的栖息地带来越来越大的压力，因此预测合适地区未来的变化，为有效的保护战略提供信息至关重要。本研究选择了东亚-澳大拉西亚迁徙路线（EAAF）沿线中国一个重要的水鸟中途停留区作为研究点。通过整合未来土地利用模拟（FLUS）模型和最大熵（MaxEnt）模型，模拟了6种濒危水鸟在不同情景下的栖息地变化，并评估了现有自然保护区的保护缺口。研究表明，城市扩张和湿地减少减少了水鸟的栖息地，并与气候条件产生复合效应。三种濒临灭绝的水鸟预计将在多种情况下在中等和高适宜性地区经历大幅扩张。平均日差、土地利用和降水季节性对所有物种的预测影响最大。濒危水鸟热点区呈持续的南移趋势，当前趋势情景和低温室气体排放路径（SSP126）下潜在热点区最大，生态保护情景和高温室气体排放路径（SSP585）下潜在热点区最小。保护缺口分析表明，目前的保护区只保护了18.0%的适宜栖息地，而且在大多数情况下，这一比例预计会下降。我们的研究结果为改善保护策略提供了有价值的信息，如增加湿地和水的恢复，减少城市扩张和扩大自然保护区网络以适应未来的变化。

Human activities have transformed marine ecosystems over millennia, leaving profound impacts on their natural state. Understanding past marine conditions provide essential baselines for assessing the scale and consequences of these long-term changes. This study sheds light on the understudied Southwestern Atlantic, where historical data on marine ecosystems are scarce, despite the region's extensive history of seafaring and coastal exploitation. We analyzed 255 historical records of Brazilian marine megafauna (including bony fishes, whales, and manatees) derived from naturalists' accounts, reports, artworks, and journals dating from 1500 to 1911, to reconstruct the recent past of coastal marine ecosystems in the region. We then compared historical information on body sizes and catches with contemporary data to reveal temporal trends across megafauna groups. Whaling persisted for over 380 years along the Brazilian coast, with a significant decline in catches until the practice was banned in 1986. Manatee hunting intensified from the early 1800s, with annual captures increasing throughout the 20th century, leading to population collapse by 1973. In 1870, historical records document grouper landings of 2560 to 3200 tons in a single region, reflecting immense fishing pressure, with catch levels continuing to rise until declines were observed in the early 2000s. Additionally, historical accounts indicate that species such as Atlantic tarpon (Megalops atlanticus) and cobia (Rachycentron canadum) attained larger body sizes in the past compared to present-day individuals, likely due to selective fishing pressure on larger specimens. These findings demonstrate the value of historical data in revealing overlooked baselines and highlight the urgent need to consider long-term (spanning decades to centuries) ecological perspectives in the conservation of the Southwestern Atlantic's marine biodiversity.

几千年来，人类活动改变了海洋生态系统，对其自然状态产生了深远的影响。了解过去的海洋状况为评估这些长期变化的规模和后果提供了必要的基础。这项研究揭示了未被充分研究的西南大西洋，尽管该地区有着广泛的航海和沿海开发历史，但海洋生态系统的历史数据却很少。我们分析了255个巴西海洋巨型动物（包括硬骨鱼、鲸鱼和海牛）的历史记录，这些记录来自于1500年至1911年的博物学家的记录、报告、艺术品和期刊，以重建该地区沿海海洋生态系统的近期历史。然后，我们将体型和捕获量的历史信息与当代数据进行比较，以揭示大型动物群体的时间趋势。在巴西海岸，捕鲸活动持续了380多年，直到1986年被禁止，捕鲸量才显著下降。从19世纪初开始，对海牛的捕猎愈演愈烈，整个20世纪每年的捕获量都在增加，到1973年导致海牛数量锐减。1870年，历史记录显示，单个地区的石斑鱼捕捞量为2560至3200吨，反映出巨大的捕捞压力，捕捞量持续上升，直到21世纪初才出现下降。此外，历史记载表明，大西洋海鲢（Megalops atlanticus）和cobia （Rachycentron canadum）等物种在过去的体型比现在的个体更大，这可能是由于对较大标本的选择性捕捞压力。这些发现证明了历史数据在揭示被忽视的基线方面的价值，并强调了在西南大西洋海洋生物多样性保护中考虑长期（跨越几十年到几个世纪）生态观点的迫切需要。

Coastal ecosystems face multiple stressors, and their responses are magnified by global stressors associated with climate change, such as warming and ocean acidification (OA). Oyster farming are vulnerable to the effects of these stressors. Environmental monitoring technologies have been proposed as an adaptive strategy to OA. This study examined the perceptions of the oyster farmers in Bahía San Quintín, Mexico, toward this strategy. Through surveys and workshops, we identified the main challenges oyster farmers face in their industry, their level of awareness about OA, and their openness to adopting new technologies. Most respondents (66 %) did not recognize OA, which suggests that they had a low perception of its risks and its potential consequences for their activities. The most frequent problems were environmental issues (48 %), such as extreme temperature events, biofouling, and predation, followed by limited technical and financial resources (34 %). Recognizing the negative effect that high temperatures have on their activity, especially during El Niño Southern Oscillation (ENSO) events, is a positive outcome, as it allows them to adopt strategies to cope with OA. The main barriers to adopt new technologies were related to management issues (56 %), including a lack of economic resources. We recommend that interactions between oyster producers, academia, and governmental actors must be strengthened to promote environmental monitoring, thus improving their adaptive capacity and reducing potential impacts of stressors on their industry, such as climate change and OA. This study case is a valuable reference for other oyster farming communities in similar environmental and socio-economic contexts.

海岸带生态系统面临多重压力源，其响应被与气候变化相关的全球压力源（如变暖和海洋酸化）放大。牡蛎养殖很容易受到这些压力因素的影响。环境监测技术已被提出作为OA的适应性策略。这项研究调查了墨西哥Bahía San Quintín的牡蛎养殖者对这一策略的看法。通过调查和研讨会，我们确定了牡蛎养殖者在他们的行业中面临的主要挑战，他们对开放获取的认识程度，以及他们对采用新技术的开放程度。大多数受访者（66%）不认识OA，这表明他们对OA的风险及其对其活动的潜在后果的认识较低。最常见的问题是环境问题（48%），如极端温度事件、生物污染和捕食，其次是技术和财政资源有限（34%）。认识到高温对其活动的负面影响，特别是在厄尔Niño南方涛动（ENSO）事件期间，是一个积极的结果，因为它使它们能够采取应对OA的策略。采用新技术的主要障碍与管理问题有关（56%），包括缺乏经济资源。我们建议加强牡蛎生产者、学术界和政府行为者之间的互动，促进环境监测，从而提高牡蛎的适应能力，减少气候变化和OA等压力源对其产业的潜在影响。该研究案例对其他类似环境和社会经济背景下的牡蛎养殖社区具有重要的参考价值。

Global climate change has intensified the risk of urban flooding, making resilience enhancement a critical disaster risk strategy. An integrated framework—combining hydrological–hydrodynamic modelling, multidimensional resilience assessment, and spatial statistical analysis at the street scale—was applied to 88 streets in the central urban area of Tianjin. Based on simulations of four heavy rainfall scenarios (50-year, 100-year, 500-year, and 1000-year), a resilience assessment framework covering four dimensions was used to evaluate the resilience level of each street under a 100-year rainfall scenario. Finally, the MGWR (Multiscale Geographically Weighted Regression, MGWR) method was used to identify the key factors that affect urban flood resilience. The results showed that: (1) The maximum surface runoff depths under four rainfall scenarios were 63.94 mm, 77.89 mm, 110.39 mm, and 124.43 mm, respectively, with flood risk following a "high in the southeast, low in the northwest" pattern. (2) The rainstorm waterlogging resilience in the study area showed a concentric pattern, with levels decreasing from the center to the periphery, characterized by "high in the center and low in the periphery". (3) Factors significantly affecting rainstorm waterlogging resilience included drainage network density, drainage pump station density, river network density, and vegetation coverage. Based on these results, horizontal and longitudinal strategies were proposed to enhance resilience. These strategies provide actionable guidance for enhancing flood resilience in low-lying coastal cities facing compound pluvial-marine flooding, advancing urban-coastal resilience planning.

全球气候变化加剧了城市洪水的风险，使增强抗灾能力成为一项关键的灾害风险战略。以天津市中心城区的88条街道为研究对象，采用了水文-水动力模型、多维恢复力评价和街道尺度空间统计分析相结合的综合框架。通过对50年、100年、500年和1000年4种强降雨情景的模拟，构建了一个覆盖4个维度的复原力评估框架，对100年强降雨情景下各条街道的复原力水平进行了评估。最后，采用多尺度地理加权回归（MGWR）方法识别影响城市抗洪能力的关键因素。结果表明：(1)4种降雨情景下的最大地表径流深度分别为63.94 mm、77.89 mm、110.39 mm和124.43 mm，洪涝风险呈现“东南高、西北低”的格局；(2)研究区暴雨内涝恢复力呈中心向外围递减的同心圆格局，表现为“中心高，外围低”。(3)排水管网密度、排水泵站密度、河网密度、植被覆盖度对暴雨内涝恢复力有显著影响。在此基础上，提出了提高弹性的横向和纵向策略。这些策略为提高低洼沿海城市面临雨海复合洪水的抗洪能力、推进城市-沿海抗洪能力规划提供了可操作的指导。

Palm oil is highly sensitive to quality degradation during maritime transport due to thermal instability, ineffective cleaning, and operational errors. This study employs the Intuitionistic Fuzzy Fault Tree Analysis method to model the uncertainty and expert-based subjectivity associated with spoilage risks. A fault tree structure was created based on expert consultation, identifying 71 basic events leading to the top event, defined as cargo spoilage. Linguistic evaluations from ten experts were converted into intuitionistic fuzzy numbers and aggregated to estimate the failure probabilities. The top event probability was calculated as 0.233, suggesting a significant likelihood of spoilage throughout the voyage. Among all basic events, insufficient steam supply, excessive steam, inadequate training, poor placement of cleaning equipment, and sensor failures emerged as major contributors. These findings indicate that spoilage stems from a combination of technical, operational, and human-related shortcomings. Improving training strategies, procedural discipline, and equipment reliability is essential to mitigate these risks. The proposed framework provides a structured and flexible methodology for analysing spoilage risks and supports effective decision making for maritime operators. It offers a valuable contribution to the safe and sustainable transport of palm oil by identifying vulnerabilities and guiding improvements in both technical systems and human performance.

棕榈油在海上运输过程中，由于热不稳定、无效清洁和操作错误，对质量退化非常敏感。本研究采用直觉模糊故障树分析法对腐败风险的不确定性和专家主观性进行建模。在专家咨询的基础上，建立了故障树结构，确定了导致货物损坏的71个基本事件。将10位专家的语言评价转换为直觉模糊数，并进行汇总，以估计故障概率。最高事件概率计算为0.233，表明在整个航行中发生损坏的可能性很大。在所有基本事件中，蒸汽供应不足，蒸汽过量，培训不足，清洁设备放置不当以及传感器故障成为主要原因。这些发现表明，腐败是由技术、操作和与人有关的缺陷共同造成的。改善培训策略、程序纪律和设备可靠性对于减轻这些风险至关重要。拟议的框架为分析损坏风险提供了结构化和灵活的方法，并为海事运营商提供了有效的决策支持。它通过识别脆弱性并指导技术系统和人员绩效的改进，为棕榈油的安全和可持续运输做出了宝贵贡献。
