Due to reduced sediment supply and strong coastal dynamics, deltaic coasts are struggling to maintain shoreline progradation, necessitating urgent needs for integrated and data-enriched vulnerability assessments to address erosion risks. However, previous studies have often been constrained by observational datasets and lacked a systematic analysis of erosion vulnerability in deltaic coasts during varying periods under combined human activities and climatic changes. The modern Yellow River Delta (YRD) serves as a typical river-dominated delta system, currently undergoing geomorphic transition and facing erosion risks due to changing environmental conditions. This study integrates methods of numerical modeling, Analytic Hierarchy Process (AHP), and Coastal Vulnerability Index (CVI) to develop a comprehensive framework for assessing coastal erosion vulnerability. We then apply this framework to evaluate the erosion vulnerability of different coastal segments of the YRD, using multi-year hydro-geomorphic and human-interfered indicators. The results reveal that the overall erosion vulnerability of the YRD has decreased during 1992–2015, characterized by pronounced spatial and temporal disparities. The abandoned northern YRD exhibits high erosion vulnerability, primarily due to the absence of fluvial sediment supply, strong coastal currents, and the additional impact of wave climate. In contrast, the artificially protected coasts and western Laizhou Bay show relatively lower vulnerability marked by coastal protection measures and weak hydrodynamic influences. The segment of Qingshuigou delta lobe shows high vulnerability in sediment-starved areas, attributable to both engineered diversions and natural channel migration. Future management strategies should integrate coastal protection measures with wetland restoration efforts, as well as optimize riverine water and sediment regulation within the river basin and deltaic channels to enhance riverine sediment delivery to severe erosion zones.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107760"},"PeriodicalIF":4.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084646","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}

Beaches are popular for their tranquil ambience and offer a variety of pursuits, such as swimming, walking, fishing, and constructing sandcastles. Coastal tourism and recreation play a significant role in national economies by attracting both domestic and international visitors. However, recreational beaches can also pose health risks due to microbial contamination from diverse human and fecal sources. The presence of pathogens in recreational beaches can lead to various health issues such as gastrointestinal, acute febrile respiratory tract, nasal cavity, ENT, eye irritation and skin-related infections. Swimming and bathing in polluted coastal waters cause over 120 million gastrointestinal illnesses and 50 million cases of severe respiratory disease annually. This not only restricts local residents and international tourists from utilizing the beaches but also results in economic losses and psychological impacts for affected individuals. Therefore, regular monitoring and assessment of recreational beach water quality is crucial in preventing contamination and the spread of infections. This review article examines the growing environmental and public health concerns surrounding microbial contamination in marine recreational areas. Despite the health risks, in developing and underdeveloped nations, the scarcity of comprehensive monitoring of recreational water quality poses significant health risks. Further, the manuscript also emphasizes the necessity for coastal and estuarine management and ocean-coastal policy recommendations to reduce risk in ocean and coastal areas by establishing threshold levels for emerging pathogens through microbial assessment and developing internationally standardized monitoring protocols that can be uniformly implemented across diverse beach environments worldwide for recreational development.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107757"},"PeriodicalIF":4.8,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072746","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}

This is a significant issue in countries where the fisheries sector plays a vital role in the economy. In Myanmar, the fisheries sector contributes up to 50 % of the animal protein for human consumption in addition to providing a livelihood for large numbers of fishers in coastal communities. However, managers in Myanmar have inadequate data for regulating coastal fisheries. To help address these data deficiencies, we implemented a digital catch data collection system to quantify the diversity and volume of catches coming from the inshore fisheries of southern Myanmar. Our data from the Tanintharyi region showed a high diversity catch (49 fish families), with commercial transactions greatly dependent on a few key families (e.g., Scombridae, Carangidae) for local and regional trading. We also identified the importance of tonguesoles (Cynoglossidae), frequently caught as bycatch, as an essential contribution to the local food supply. Tonguesoles are unreported and unregulated but are of high socio-economic importance, providing a source of affordable, high-quality protein and income to coastal communities. Here we use Cynoglossidae as an example of a single fish family that can be used to make general management recommendations for a poorly understood but highly diverse inshore fishery in Myanmar. An ecosystem approach to fisheries management (EAFM) is suggested for the tonguesole and related mixed-fisheries to ensuring long-term sustainability of fisheries, food security, biodiversity, other ecosystem services, and safeguard coastal livelihoods across the large coastal area of Myanmar.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107743"},"PeriodicalIF":4.8,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070735","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}

In coastal China, where rapid socioeconomic development intersects with increasing climate hazards, coastal governance faces growing challenges in managing such compound risks. However, limited research has quantified the economic exposure to HDCEs under various warming scenarios, which is crucial for guiding adaptive governance and sustainable coastal development. This study quantifies sectoral economic exposure to HDCEs under 1.5 °C, 2.0 °C, and 3°0 C global warming scenarios, using multi-model climate ensemble and gross domestic product (GDP) projections from the SSP-RCP framework. Results show that total GDP exposure in coastal China in three warming scenarios will increase by 12.54 ± 0.63, 15.38 ± 1.83, and 61.64 ± 8.73 times, respectively, relative to the base period (1995–2014). Notably, northern coastal China exhibits much higher exposure than eastern and southern regions, and the tertiary sector is projected to face the largest increase, reaching up to 125.05 ± 17.70 times under the 3.0 °C scenario. The dominant contribution (48 %–71 %) to exposure increase stems from the interactive effect between climate and GDP change. By linking these findings to sustainable development goals (SDGs) like SDG8 (Decent work and economic growth) and SDG13 (Climate action), this study provides actionable insights for strengthening adaptive coastal governance. We underscore the urgency of prioritizing the tertiary sector and high-exposure regions in climate adaptation plans.

Although assessment processes of comprehending the risk and vulnerability level have guided only limited action, these remain valuable tools for an <em>‘objective’</em> means to identify targeted areas focusing on <em>‘particularly’</em> vulnerable. A holistic understanding of how these assessments are conceptualised and operationalised is necessary to understand the challenges that hinder effective translation of the results into actionable decisions. The study combines two complementary methods—bibliometric analysis and systematic review—to synthesise the literature on risk and vulnerability assessment in coastal systems to natural hazard processes. Bibliometric analysis, an established research methodology, was used to analyse trends in publication, author and journal information, hotspot themes and their co-occurrence. A systematic literature review was done to gather specific insights on the regions of study, type of hazards studied, scale of reporting, methods and tools used, indicators used, gaps identified, policy analysis and the reported usability of the risk assessment outputs. We reviewed 178 studies published between 2000 and 2024. The results report (1) nearly twofold growth in studies in the domain of vulnerability and risk assessment in the last 5 years as compared to the previous decade; (2) majority of research focused on the eastern coastal states of West Bengal, Tamil Nadu, Odisha, and Andhra Pradesh; (3) half of the reviewed studies focused on risk or vulnerability arising due to multiple hazards, followed by cyclones (15.7 %); (4) indicator-based assessments were the most commonly used method (63 %); (5) biogeophysical indicators were more commonly investigated than socioeconomic and (6) the administrative level of reporting majorly focussed on villages (37.9 %). After quantitatively analysing previous research based on qualitative assessment, the study reports significant vagueness in definitions of risk (and vulnerability) and conceptual frameworks.
