At an international level, they bring together countries to conserve shared marine resources, sometimes in regions with political tensions. This cooperation to conceive solutions to common threats to the ocean among countries with adversarial political relationships is termed “Ocean Science Diplomacy” (OSD). The purpose of this Short Communication is to describe how the Gulf of Mexico MPA Network (RedGolfo) embodies OSD, as well as to show how MPA networks have been used globally as tools for OSD. RedGolfo is a network of 11 MPAs in Mexico, Cuba, and the United States and it was created in 2017 despite decades of political tension. As the members of RedGolfo have worked to determine the network’s priorities and objectives, they have found great value in looking to lessons learned from other MPA networks. Connecting MPA networks globally will accelerate the implementation of best practices so that global conservation targets (e.g., Target 3 of the Global Biodiversity Framework) can be reached.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106709"},"PeriodicalIF":3.5,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143828915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ocean SDG was successfully championed by Pacific Island Countries with cooperation from other Small Island Developing States (SIDS). The special needs of SIDS are considered within two SDG 14 targets. Trinidad and Tobago is a SIDS located in the Caribbean region, with collectively 704 km of coastline and fifteen times more sea than land space under its territory. The country relies heavily on its marine areas for economic prosperity, but the continued degradation of its coastal and ocean resources and ecosystems has been documented. Despite this, in its Voluntary National Review 2020 on the implementation of the SDGs, SDG 14 was not included. Having passed the mid-way point for SDG implementation, this paper explores the implementation status of SDG 14 in Trinidad and Tobago, and provides recommendations to achieve the SDG 14 targets. Of the four SDG 14 targets that matured in 2020, none has been achieved. However, some progress has been made towards achieving the targets and further opportunities exist, despite the many challenges faced by SIDS. Five key recommendations for Trinidad and Tobago to advance the SDG 14 agenda and achieve the goal within the current decade are provided.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106713"},"PeriodicalIF":3.5,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This systematic review, conducted using the PRISMA protocol, evaluates 40 coastal related studies to assess ANN architectures, input variables, training techniques, and performance metrics. Findings indicate that Multi-Layer Perceptron (MLP) remains the most widely used ANN architecture, while hybrid approaches, including genetic programming and two-step networks, enhance prediction accuracy. Although Long Short-Term Memory (LSTM) and Convolutional Neural Networks (CNNs) have been explored, their applications remain limited. Research is predominantly concentrated in Asia and Europe, underscoring the need for expansion to Africa and South America. Despite advancements, challenges persist, including data scarcity, optimal data combinations, and model interpretability. Most studies focus on short-term predictions, often neglecting long-term coastal changes driven by climate change and sea-level rise. Additionally, ANN performance in predicting storm-induced erosion remains inconsistent, as extreme storm events introduce rapid, nonlinear changes that are difficult to model. Key research gaps include the integration of real-time data sources (e.g., wave, sediment, shoreline profiles, and storm data), improved model transparency, and better consideration of long-term shoreline evolution. Addressing these challenges will enhance ANN-based coastal prediction models, supporting adaptive management, early warning systems, and sustainable erosion mitigation strategies.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106704"},"PeriodicalIF":3.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the socioeconomic dynamics of government expenditures on marine ecosystem sustainability in Nigeria, with a particular focus on the fishing ground load capacity factor (FGLCF). Using data from 1981--2022, the analysis employs dynamic autoregressive distributed lag modelling and kernel-based regularized least squares to uncover the impacts of disaggregated government spending—administration, economic services, and social and community services—on marine sustainability. The findings reveal that administrative expenditure negatively affects FGLCF, reflecting inefficiencies and a diversion of resources from ecological priorities. Economic service spending has an insignificant impact, underscoring the need for targeted investments in sustainable infrastructure. Conversely, social and community expenditures positively influence FGLCF, demonstrating their critical role in promoting sustainable practices through education, healthcare, and community engagement. The study also identified population growth and economic expansion as significant drivers of marine resource depletion. These findings offer actionable insights for policymakers to achieve a balanced relationship between economic progress and the long-term resilience of marine ecosystems in Nigeria. Key policy measures include optimizing resource allocation, mandating environmental assessments for infrastructure projects, and significantly increasing investments in education and healthcare. These strategies aim to align fiscal policies with ecological sustainability, ensuring both economic progress and the preservation of vital natural resources.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106701"},"PeriodicalIF":3.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, impacts that are evaluated using only AIS-based vessel data (e.g. counts) are likely underestimating the volume of vessel traffic, and thus the potential and scale that effects may occur. The extent of this underestimation is unclear due to the lack of data on the volume and distribution of vessels that are not transmitting AIS. To investigate this, &gt; 1800 hours of land-based and at-sea visual surveys were conducted across nine Scottish Marine Regions between 2019 and 2024, collecting data on coastal vessel activity (&lt;10 km of shore). These data were compared with corresponding AIS data to quantify AIS vs non-AIS traffic. Non-AIS vessels were present during 67 % of the total time surveyed. Of the vessels recorded, only 43 % were broadcasting AIS. AIS transmission rates were varied between seasons (range = 38–55 %), regions (range = 20–58 %), and by vessel type (range = 0–95 %). Given AIS data is increasingly being used to quantify vessel activity and predict associated impacts, it is vital that further consideration is given to the volume of vessel traffic absent from these datasets and predictive efforts.

A comprehensive methodology was employed to assess aquaculture’s social acceptability, utilising a survey questionnaire, stakeholder workshops, and literature reviews to break down the concept of social acceptability into identifiable factors. Findings indicate that effective governance and enhanced coordination among authorities are crucial for improving aquaculture’s social acceptability. This study highlights the need for participatory decision-making processes that actively engage local stakeholders, emphasising the importance of transparent and effective communication regarding the quality and safety of aquaculture products, with the aim of increasing public awareness and trust. Furthermore, integrating aquaculture with other coastal activities and promoting economic benefits can improve aquaculture’s social acceptability. Addressing environmental concerns and adopting better management practices are essential for mitigating negative perceptions associated with aquaculture development. Finally, this study highlights the essential role of social acceptance in aquaculture development, emphasising the need to prioritise transparency, inclusivity, and public engagement in governance to support policies that promote sustainable aquaculture practices.

A semi-structured questionnaire was designed to gather data on harvester awareness of climate change and its perceived impacts on their fishery and livelihoods. Dockside interviews were conducted with 287 lobster harvesters in the twelve Lobster Fishing Areas that surround the province. The results show that most harvesters are aware that climate change is occurring, and that they are also concerned about its impact on the lobster fishery. Nevertheless, suggested climate adaptation measures were generally not well received.
