Key to achieving its desired outcome of increasing understanding of the complexity of human-ocean relationships is understanding how these relationships are managed through marine planning and regulatory processes. As a complementary concept, process literacy involves increasing understanding of the operation and complexity of regulatory and planning policy processes. In this paper we consider the alignment of the concept of process literacy to ocean literacy to operationalise the latter and ensure that developing more nuanced understandings of how marine spaces are managed is central to ongoing ocean literacy efforts. Using the UK as a case example, we define the dimensions of process literacy and discuss the importance of increasing knowledge and awareness of marine decision-making processes to democratise marine spaces. Where ocean literacy is increasingly inclusive of the complexities of socio-ecological ocean systems, the addition of process literacy speaks to the need to understand political and wider governance processes to gain understanding of the practicalities of human-ocean relationships. In this paper we discuss the relationship between ocean literacy and process literacy before outlining definitions for process literacy dimensions. We define process literacy as a crucial component of ocean literacy and explore its links with spatial justice. As an emerging area of research and practice, we provide recommendations for future directions to support ongoing efforts to realise the potential of ocean literacy.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106731"},"PeriodicalIF":3.5,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843002","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 review investigates the multifaceted nature of power by applying the Power Cube framework and the four dimensions of power, focusing on their implications for governance and resource management. The analysis reveals that centralized decision-making, traditional authority, neoliberal policies, and external actors significantly shape power relations, often marginalizing local communities and small-scale fishers. The review further explores how these dynamics contribute to sustainability challenges while highlighting the importance of addressing structural inequalities to promote equitable governance. By examining case studies and existing literature, this paper underscores the need for inclusive approaches that empower marginalized stakeholders and foster collaborative governance. The findings suggest that recognizing and addressing power asymmetries is crucial for achieving sustainable and just outcomes in marine conservation and fisheries management. Ultimately, this review contributes to a deeper understanding of power relations in natural resource governance and offers practical insights for enhancing policy frameworks in Sub-Saharan Africa.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106732"},"PeriodicalIF":3.5,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843001","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}

Data were collected from 3159 respondents across 18 marine ecoregions using quantitative surveys and qualitative interviews to capture perspectives. Findings indicate that younger and more educated individuals prioritize marine research and pollution control, while older respondents emphasize economic stability and resource management. Gender differences are evident: statistical analysis (Chi-square, Cramér’s V) shows that women express greater concern for environmental protection and pollution impacts on household and community health (p &lt; 0.01, moderate effect size), whereas men are more inclined toward the economic utilization of marine resources, often linked to fisheries and maritime occupations. Occupational status also influences attitudes toward marine sustainability, with employees and students showing stronger support for conservation policies than self-employed individuals and fishers, who prioritize economic considerations and financial security (p &lt; 0.05, moderate effect size). Long-term coastal residents are more engaged in marine sustainability efforts compared to recent arrivals, exhibiting stronger advocacy for conservation measures (p &lt; 0.01, moderate-to-high effect size). These findings highlight the necessity of integrating demographic insights into marine policy to ensure inclusive, adaptive, and effective governance. To align with the Indonesian Ocean Policy (IOP), this study recommends targeted interventions, including gender-sensitive environmental education, financial incentives for sustainable small-scale fisheries, and place-based marine governance strategies incorporating customary tenure systems (e.g., <em>sasi laut</em>). Embedding these demographic considerations in policy frameworks ensures effective, socially responsive, and equitable marine conservation strategies in Indonesia.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"178 ","pages":"Article 106706"},"PeriodicalIF":3.5,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838324","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}

People increasingly recognize the importance of stakeholder analysis in ensuring the sustainability of natural gas exploitation and mitigating ecological consequences for coastal forest ecosystems. This study employs an exploratory research design, utilizing NVIVO 12 Plus Software to collect and analyze qualitative data, identifying four key stakeholder categories: key players, context setters, subject players, and intermediaries. Key players are influential decision-makers with a vested interest in natural gas exploitation, while context setters, though equally influential, are primarily concerned with coastal forest ecosystem management and require targeted engagement to remain informed and satisfied. Stakeholders with limited influence but high interest require continuous communication and information-sharing to keep them engaged. Meanwhile, intermediaries play a key role in fostering sustainability by balancing both influence and interest. The findings highlight the critical need to balance natural gas exploitation with coastal forest conservation and management. Achieving this balance involves integrating environmental management practices into natural gas policies, plans, and programs to address concerns over biodiversity and ecosystem degradation. Stakeholder analysis is a powerful tool for fostering collaboration and designing innovative decision-making approaches that prioritize both sustainable development and ecological conservation. By addressing stakeholder concerns and promoting joint planning, such efforts can mitigate the adverse impacts of natural gas exploitation on coastal forests, ensuring a more sustainable path forward.

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 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.

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.
