Our findings suggest that investment decisions are shaped by a combination of strategic, economic, and political factors, with ports in piracy prone regions and economically vulnerable countries more likely to receive investment. By modeling the sub-themes of security and economic instability, this study provides a nuanced understanding of China's port investments and their implications for global maritime policy.

This study presents a Nash bargaining-based cost-sharing model led by the WEC-investor, exploring three scenarios of fairness preferences: held solely by the supplier, solely by the investor, and jointly by both. Subsequently, variations in pollution control efforts, compensation ratio, and stakeholder profitability across these scenarios are comprehensively compared and analyzed. A real-case study is employed to validate the model and assess scenario-specific outcomes. Results indicate that mutual fairness recognition enhances pollution mitigation, economic performance, and compensation stability. In contrast, unilateral fairness consideration risks coordination breakdowns and free-rider behaviors, weakening environmental and economic results. Furthermore, moderate fairness fosters cooperation and efficiency, while excessive emphasis on fairness may undermine economic viability, particularly for profit-sensitive actors. Findings offer actionable insights for refining WEC frameworks and emphasize the role of fairness in promoting integrated, sustainable governance at broader scales.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107821"},"PeriodicalIF":4.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322737","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}

The safety of lives and property in coastal zones can only be ensured when the biophysical capacity for coastal protection services adequately meets demand. Yet existing capacity-demand models often fail to account for the combined impacts of marine and terrestrial hazards (e.g. extreme rainfall coinciding with storm surges) and the mitigating effects of human critical infrastructure (e.g. dikes). To address this gap, we analyzed 228 county-level coastal assessment units along the Chinese mainland. First, we measured the biophysical capacity of coastal protection services using five indicators related to natural ecosystem properties. Next, we evaluated demand for coastal protection services by integrating six natural hazard indicators, four human exposure indicators, and four social adaptive capacity indicators into a risk reduction model. Finally, we identified nine distinct types of capacity-demand relationships across space (High-Low, High-Medium, High-High, Medium-Low, Medium-Medium, Medium-High, Low-Low, Low-Medium, and Low-High). Seventy-seven counties exhibited relatively low capacity and relatively high demand, located mostly in Guangdong and Jiangsu provinces. Furthermore, we found that many economically underdeveloped counties showed capacity-demand mismatches (e.g. the coastal counties of Hainan Province), perhaps because local infrastructure development has not kept pace with overall economic growth. This study provides a comprehensive framework for identifying spatial patterns of coastal protection services capacity-demand mismatches, thereby informing decision-making to enhance disaster resilience in China's coastal zones.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107815"},"PeriodicalIF":4.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312532","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}

Employing a mixed-methods approach, data was systematically collected through focus group discussions and in-depth key informant interviews, at various administrative levels. The findings reveal the key role of mangroves in enhancing livelihoods, economic resilience, and community well-being. In integrated systems, mangroves boost aquaculture yields and provide additional income through activities such as seafood foraging, while also contributing to recreation and social cohesion. Despite these benefits, challenges persist, including concerns about sustainability, market access, and regulatory barriers. Governance issues, such as inconsistent enforcement of the Forestry Law and unauthorised aquaculture conversion, highlight the need for more transparent and effective management. Historically, Vietnamese policies have put a greater emphasis on development rather than long-term ecosystem health, yet current trends show a shift towards prioritising mangrove conservation. Effective mangrove management requires an inclusive, ecosystem-based approach that addresses conflicting interests and institutional dynamics. Community perspectives reveal the necessity for equitable benefit distribution and active participation in decision-making. Future research should focus on integrated strategies for mangrove restoration and community development, including creating conservation-related job opportunities to enhance monitoring efforts and support sustainable management.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107812"},"PeriodicalIF":4.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312533","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}

Indonesia's decision to move its capital from Jakarta to ‘Nusantara’ (IKN) in East Kalimantan exemplifies these challenges, particularly for local communities. This study examines the socio-ecological impacts of this development on coastal communities in Balikpapan Bay, a critical yet underexplored context in Indonesia's new capital project. Drawing on ‘powers of exclusion’ and ocean-grabbing theories, it investigates how government regulations, legitimation, market dynamics, and force intensify the exclusion of coastal communities in Balikpapan Bay, and how IKN's development reshapes access and fishers' relations to coastal resources. Employing qualitative methods, it draws on from field research in several villages around Balikpapan Bay. Findings reveal that the new capital development exacerbates long-standing exclusion of coastal communities, particularly for fishing groups. Pressures from the logging, mining, and plantations had already limited fishermen's access and IKN development deepens this exclusion, disrupting fishers' livelihoods, and sparkling social conflicts over shrinking resources. The study highlights the state's role in legitimizing exclusions under development narratives, prioritizing state and corporate interests over local communities. This research contributes to a deeper understanding of the socio-environmental ramifications and trade-offs inherent in large-scale infrastructure projects like capital relocation. This research underscores the urgent need for inclusive approaches in coastal governance to reconcile large-scale development with socio-ecological justice, offering critical insights for policymakers and development practitioners worldwide.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107801"},"PeriodicalIF":4.8,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307809","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}

The simulation is done by first estimating the impacts of GHG pricing on maritime transport costs using data obtained from intermodal logistics models and voyage statistics. Second, these cost estimates are applied in a computable general equilibrium model to evaluate their impacts on trade and GDP at global and regional levels. Findings suggest that price levels that would cause a modest increase in maritime transport costs would have limited impacts on overall trade and the global economy. However, the effects differ among countries, influenced by the economic scale and reliance on maritime transport. Through model application and comparison with existing literature, these models prove helpful in identifying appropriate price levels that would avoid generating excessive negative impacts on a global scale. They also highlight important elements for devising a mechanism to address disproportionate negative impacts of the measure on countries. Since estimated economic outcomes are influenced by specific modeling techniques, using modeled results to determine the beneficiaries and modalities of such mechanisms necessitates thorough analysis.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107804"},"PeriodicalIF":4.8,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308068","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}

Initially, we develop a space template that utilizes resilient subblocks rather than traditional fixed subblocks, while considering the operational requirements of YCs. Subsequently, YC deployment is optimized based on the generated template. This presents a complex problem that is typically addressed using heuristic algorithms; however, heuristic algorithms cannot guarantee the quality of solutions.

To address these challenges, many regions, including China, have introduced exit policies aimed at supporting coastal fishermen in exiting the declining fishing industry. This study focuses on Zhejiang Province, a region that has implemented one of China's most comprehensive exit policies, and examines the attitudes of coastal fishermen toward these policies. Using data collected through focus group discussions and semistructured interviews with 67 key stakeholders, including active fishermen, former fishermen, government officials, and fisheries professionals, this study reveals critical insights. Although most fishermen acknowledge the importance of resource conservation and generally support the goals of the exit policies, 82 % of active fishermen perceive significant shortcomings in these policies, and over 70 % indicate that under the present framework, they have no intention of leaving the industry, primarily because of concerns over livelihood security. Specifically, they cite insufficient compensation, unappealing reemployment support, and issues of policy fairness as major barriers to exit, which significantly undermines their willingness to participate in the policies. Additionally, the persistence of illegal, unreported, and unregulated fishing activities is perceived to weaken the ecological effectiveness of the policies. The findings underscore the importance of designing inclusive, participatory, and fishermen-centered exit policies. Ensuring the active engagement of stakeholders, particularly fishermen, in policy formulation and implementation is crucial to achieving the dual objectives of ecological conservation and socioeconomic development. The lessons learned from this study provide practical guidance for other regions facing similar overfishing challenges and offer valuable insights for the development of sustainable fisheries management policies worldwide.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107817"},"PeriodicalIF":4.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297811","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}
