Despite growing recognition of these challenges, existing research has not clearly identified the key sustainability dimensions that require attention in these regions. To address this gap, this study evaluates the sustainable development capacity of coastal zones in 41 developing countries, using an integrated indicator system that encompasses environmental, social, and economic spheres across seven themes. This analysis also explores the synergies and trade-offs among these themes to identify management priorities. Furthermore, future trends in sustainable development capacity are projected under three Shared Socioeconomic Pathways (SSPs). The results indicate that these countries have an average coastal sustainable development capacity score of 52.18 out of 95, with relatively high scores in social development (mean score: 63.40) and ocean (61.31) themes, while biodiversity (40.96) and freshwater (43.62) themes score relatively low. The highest synergy is observed in the atmosphere (hub score = 1.00) theme, while the highest trade-offs are found in the ocean (1.00) and land (0.78) themes. Trade-offs are particularly prominent in low-income countries' land (1.00) theme, in middle-income countries' ocean (1.00) and social development (0.75) themes, and in high-income countries’ ocean (0.85) and land (1.00) themes, as categorized by coastal GDP per capita. Under the SSP1-1.9 scenario, sustainable development capacity is projected to increase relatively rapidly. This study provides valuable guidance and theoretical foundations for formulating coastal sustainable development strategies in developing countries.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"273 ","pages":"Article 108050"},"PeriodicalIF":5.4,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790269","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}

These ecosystem changes have greatly impacted fish distribution, abundance, and overall production. To ensure effective and sustainable management of fishery resources amid a changing climate, vulnerability assessments have become increasingly important. This study undertook a comprehensive vulnerability assessment by evaluating the cascading effects of rising SST under the RCP 8.5 scenario on 51 commercially important marine species, processing operations, and dependent communities. Results showed that species highly exposed and sensitive to climate change, mainly <em>Scomber australasicus</em>, <em>Gazza minuta</em>, and <em>Secutor insidiator</em>, exhibit heightened vulnerability. Consequently, processing sectors largely reliant on these species, specifically drying and smoking, along with areas characterized by diversified processing activities, are at greater risk. Such vulnerabilities generally translate into shortages of raw materials, disruptions in supply chains, and reduced production efficiency, all of which can negatively affect food security, economic stability, and community livelihoods. The identification of the most vulnerable species, sectors, and areas in this study offers a strategic framework for guiding adaptation measures, prioritizing resource allocation, and informing policy interventions. Mitigating these interconnected vulnerabilities demands a proactive, science-based approach to resource management that underline sustainability, adaptive capacity-building, and the development of resilient supply chains to safeguard the long-term viability of Philippine fisheries and their associated industries.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"273 ","pages":"Article 108060"},"PeriodicalIF":5.4,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790271","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}

Here, we examined the bio-geomorphologic controls underlying this spatial heterogeneity through year-round field investigation in a mangrove ecosystem along China's southern coast. Field observations across an elevation gradient revealed that sediment organic carbon stocks generally decreased with lowering elevation, with vegetated zones storing significantly more organic carbon than adjacent bare mudflats. Further analysis demonstrated that wave-induced bed level variability—rather than sediment input alone—was the primary factor governing carbon storage in the sediment. Vegetated zones had much higher sediment organic carbon stocks than bare mudflats due to the reduced hydrodynamic disturbance provided by the vegetation. Despite receiving six times more sediment input, the sediment carbon stock in the top 15 cm of bare mudflats was less than 25 % of that in the vegetated zones, due to experiencing at least three times more erosion and carbon loss. These findings establish a bio-geomorphologic framework for understanding heterogeneous carbon sequestration within mangroves and extend to other vegetated blue carbon habitats. By providing empirical evidence for the regulating role of bio-geomorphologic feedbacks, this study enhances predictive understanding of organic carbon burial processes and informs long-term assessments of coastal carbon sink dynamics under changing environmental conditions.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"273 ","pages":"Article 108054"},"PeriodicalIF":5.4,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790817","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}

On average, seals depredated 25.5 % (±38.1 % SD) of the catch per fishing event. Depredation rates varied markedly by gear type, target species, and location. Nets and handlines targeting pelagic and demersal fish experienced the highest losses, particularly when large numbers of seals were observed near vessels. In contrast, traps and shellfish fisheries showed minimal depredation. Our findings suggest that proximity to the seal haul-outs, high-value target species, and passive gear types increase vulnerability to seal interactions.

However, the outcomes of BCPs on traditional rights holders, especially in developing countries are often debated. This study explored stakeholders' perspectives on the feasibility of establishing BCP as a conservation financing tool and an alternative livelihood strategy in mangrove-dependent coastal communities in Tanzania (Rufiji Delta, Kigamboni, Kinondoni and Bagamoyo Districts). Data were collected through participatory rural appraisal methods, household questionnaire surveys, and field observations. The results revealed that over 76 % of respondents were strongly willing to engage in mangrove conservation through BCP, particularly in the Rufiji Delta and Kigamboni. Across all sites, respondents commonly felt that preserving mangrove ecosystems through BCP offers broader co-benefits beyond natural climate solutions. Mangrove provisioning services were most recognized by the communities, followed by regulating, cultural, and supporting services. Government representatives and local fishermen were identified as key stakeholders to be involved in the BCP. Prior to the initiation of BCP, five major risks that could jeopardize BCP execution were identified, which included limited knowledge and expertise regarding carbon credits, uncertainty about project timelines, inadequate monitoring, unclear guidelines for benefit-sharing mechanisms, and disputes over resource ownership and access rights. Some of the co-designed alternative livelihood scenarios were perceived to have both beneficial and detrimental impacts on mangroves in the future. Fish farming within mangroves was seen as a threat to ecosystem services, whereas beekeeping was viewed positively for its socio-ecological merits. To ensure that the benefits of the BCP outweigh the associated risks, our findings call for strong collaboration among stakeholders, clear policy guidelines, and recognizing local resource users as custodians of conservation rather than culprits of degradation. Overall, a deeper understanding of community willingness to participate in BCPs is important for informing future project designs and policy reforms tailored to specific contexts, and can strengthen the link between resource users and blue carbon investors.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"273 ","pages":"Article 108048"},"PeriodicalIF":5.4,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790816","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}

We evaluated how course participation impacted confidence and knowledge (self-reported and objective) using pre- and post-course assessments. Additionally, we evaluated the extent to which program participants differed from non-participants using a survey that measured self-reported confidence and knowledge, perceptions of their influence on management and their influence on clients, and environmental attitudes as measured with the New Ecological Paradigm (NEP) scale. Pre-post comparison showed program participation increased at least short-term self-reported confidence, and self-reported and objective knowledge. Additionally, guides who completed the program had higher perceived influence on management compared to those who did not participate. In concert, these results suggest that education programs may positively alter expert knowledge, confidence and, potentially, willingness to engage in management or participatory approaches, though the design of this study limits causal inferences.

Boating activity peaked during lobster sport season, with most boats engaged in diving to target lobsters. During lobster season openers, dive boats were widely dispersed and occupied roughly twice as many grids as on non-lobster days and shifted from the oceanside (dominant during the closed season) to the Gulfside of the Florida Keys. Persistent hot spots of diving activity were identified across decades: on the Gulfside during lobster season openers and on the oceanside near or within Florida Keys National Marine Sanctuary Preservation Areas during non-lobster days.

In this study, we combined high-resolution benthic habitat mapping and seascape ecology metrics to identify priority areas for conservation in the Puerto Morelos Reef National Park (PNAPM). Quantitative analysis of benthic substrates allowed the classification of five habitat types: seagrass dominated, medium coverage of seagrass and sand, sand dominated, medium coverage to algal dominated over calcareous matrix, and reef crest. A thematic map was constructed using a supervised classification of a PlanetScope satellite image (overall accuracy = 85.1 and Kappa coefficient = 0.8), from which habitat patch complexity, patch-level connectivity, and β-diversity were calculated. These spatial layers were integrated using a weighted overlay analysis and an iterative process with all possible weight combinations to obtain an optimal map of the priority conservation areas. Habitats with high seagrass coverage dominated the PNAPM seascape, and eight high-priority zones were identified, mainly along the reef crest and northern reef lagoon, where management activities should be focused. The results of our analysis support the conservation objectives of the protected area and serve as a basis for updating the outdated management program.
