While conventional management might address such a situation with narrow focus, ecosystem based management provides a more holistic and adaptive option allowing for multiple objectives and values. Such an approach has some commonality with that of the Indigenous Māori of New Zealand, who have holistic, interconnected and intergenerational aspirations. In this study we utilised Te-Rerenga-Parāoa, Whangārei Harbour, Aotearoa New Zealand as a case study to explore how ecological and Māori knowledge systems and approaches may align to address complex multi-stressor and multi-value scenarios common to estuarine systems. To achieve this we co-developed a Bayesian network heuristic modelling tool which provided a probabilistic framework to consider the relationship between stressors and the outcome states for ecological function and cultural values. The process of model development itself was a rewarding exercise of joint learning. For example, this process illustrated that while western ecological values can focus on endpoints such as abundance, cultural values were more diverse, experiential in nature, with value often centred on a cultural practise being enabled, not just the ecological component the value was connected to. Once the model was developed we considered three specific scenarios relating to harbour dredging, environmental degradation from land use changes, and fishery extraction. Model predictions for these scenarios generally matched expectations, but were generic in nature and could therefore benefit from more specificity relating to aspects such as spatial scale and context around cultural interpretation. Overall, the model demonstrated generic utility as an interactive educational tool for resource managers considering the broader impacts (on ecology and cultural values) of major societal challenges.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"258 ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425290","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 coupling model integrates the hydrodynamic model, wave model, sea ice model, and Lagrangian particle tracking model. The results demonstrate that sea ice inhibits water exchange in the northern Liaodong Bay due to a clockwise residual circulation. Conversely, sea ice enhances water exchange in the southwestern areas, specifically Bohai Bay and Laizhou Bay. This conclusion is supported by further calculations and analyses of half-life time and volumetric flow rate. Considering the impact of adjacent bays, the percentage of residual particles in the southern area after simulating a severe ice period is 33.5% higher compared to scenarios without this consideration. Finally, the uncertainty of the model was evaluated by altering the quantity of tracer particles, and the validity of the model results was confirmed through comparisons with measured chlorophyll-a and dissolved inorganic nitrogen concentrations.

However, unavailable real-time open port data complicate effective quantitative evaluations of port development along the 21st-Century Maritime Silk Road. This research addresses these issues by combining deep learning with remote sensing, using image data from key ports. A method was proposed to classify port facilities and energy reserve information spatially. A multi-classification framework using U-Net semantic segmentation was developed to segment key facilities in remote sensing data sets. The You Only Look Once v8 (YOLOv8) model was applied to locate oil tanks within Ningbo Port. The actual roof area of oil tanks was then extracted using a deep learning model, facilitating statistical analysis and comparative studies with other major oil and gas ports. Additionally, the real-time remote sensing image index calculated oil tank heights based on shadow lengths for capacity measurement of floating roof tanks. Experimental results showed a pixel accuracy of 90% and an intersection over union of 84% for oil tank region extraction, with an oil tank recognition model achieving a mean average precision of 98.9%. Compared with traditional Hough transform methods, the average absolute error, average relative error, and standard deviation for tank roof area calculations were reduced by 229.18 m², 4.6%, and 81%, respectively. This framework effectively determined the number of oil tanks in various ports, enabling real-time reserve detection and providing a data foundation for energy port management and resilience research.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"258 ","pages":"Article 107413"},"PeriodicalIF":4.8,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425288","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}

Rapid urbanization has led to ecological issues, such as the degradation of key ecosystem services (ESs) in coastal cities. Understanding the impact of urbanization on the supply and demand of ESs in coastal cities is crucial for ensuring the healthy and sustainable development of the socio-economy in these areas. This study takes the coastal city of Qingdao as a case study, with a focus on the supply and demand relationships of seven key ESs—carbon sequestration, food production, habitat quality, recreational capacity, soil retention, water yield and marine aquaculture—as well as their responses to population growth, economic development, and spatial expansion, which are three distinct aspects of urbanization. The findings indicate that: (I) From 1992 to 2022, the evolution of different ESs exhibited variability, all displaying notable spatial imbalances. (II) During this period, the urbanization process in Qingdao had a pronounced negative effect on the supply and demand of ESs. Spatial urbanization had the most significant impact on carbon sequestration, food production, habitat quality, water yield, and marine aquaculture, while population urbanization most notably affected recreational capacity. (III) The sensitivity of different types of ESs to population, economic, and spatial urbanization varies. Carbon sequestration, food production, recreational capacity, soil retention, water yield, and marine aquaculture were most sensitive to economic urbanization, whereas habitat quality was most sensitive to spatial urbanization.

Many of these communities are also socio-economically marginalized, with high levels of poverty, limited access to education, and less accessibility to basic livelihood amenities. This marginalization further exacerbates their livelihood challenges due to frequent climatic hazards and drastic changes in climatic characteristics. Disruptions to the livelihoods have far-reaching consequences such as food insecurity, unemployment, low per capita income and out-migration. In view of that, the main objective of this study is to assess spatial variation of livelihood vulnerability of local communities at the village level based on collection of enormous primary survey data. To fulfil the aim of the research, field survey data were collected from door-to-door surveys conducted in 148 villages within the study area between 2020 and 2021, encompassing about 9216 households. Using these data, community livelihood vulnerability has been assessed based on the Composite Index Approach (CIA) and LVI-IPCC framework method. While LVI-CIA uses a single composite score, LVI-IPCC combines physical and socio-economic parameters. Despite this difference, LVI-CIA is a reliable proxy for a more comprehensive LVI-IPCC. The analysis revealed that livelihood vulnerability spatially varies from coast to interior villages of the MBI. The vulnerability is showing high to very high (&gt;0.47) for those who have limited access to resources and services as well as settle in physically challenging riverine villages, which account for almost 26.43% of the population. Contrarily, accessibility and well-connectedness with the mainland, alternate livelihood options, and infrastructural facilities help minimize livelihood vulnerability (LVI -&lt;0.061) of the communities living in inland villages (56%) of the northern part of the MBI. For achieving a sustainable livelihood, this study finds out the major factors of livelihood vulnerability and also suggests mitigation measures to address their specific needs and challenges.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"258 ","pages":"Article 107410"},"PeriodicalIF":4.8,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425289","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}

Yet studies that empirically assess the effects of BPs on social-ecological outcomes (e.g., fishers' catches, revenues, and level of support towards management measures) remain limited. This study aimed to assess the effects of adopting BPs on catch per unit of effort (CPUE), revenue per unit of effort (RPUE) and small-scale fishers' perceptions in two Marine Protected Areas (MPAs) in Campania, Italy (Santa Maria di Castellabate (CAS-MPA) and Regno di Nettuno (NET-MPA)). Two BPs were implemented and tested in the two MPAs: i) five selective gears with three different mesh/hook sizes and ii) a participatory approach to increase dialogue between fishers and managers. The results from 36 surveys with small scale fishers and 158 SSF operations monitored using photo-sampling and image analysis techniques (between 2020 and 2022) are presented. Analyses of landings showed that significant differences in CPUE and RPUE between mesh/hook sizes were found in a limited number of cases (i.e., combination of fishing gears used in the 2 MPAs). Significant but divergent effects were found on CPUE in the two MPAs for gillnet used to target amberjack (GNA) only. RPUE was significantly higher in the NET-MPA when adopting the largest mesh size for GNA and the largest hook size for bottom longlines (BLL). When analyzing perceptions, fishers generally reported that the BPs adopted had a positive impact on their revenues, improved their relationship with MPA managers and increased their support for the MPA. In addition, eight stakeholder focus groups were held which helped investigators better understand the context, feedback the data gathered from the research and open up dialogue between the relevant stakeholders. The study concluded that increasing mesh/hook sizes, within the range tested here, does not negatively impact fishers’ revenues, while likely improving the status of target populations. Moreover, increasing dialogue between fishers and decision-makers can generate more positive perceptions towards the MPA and improve mutual understanding, helping to reconcile biodiversity conservation with human wellbeing for SSF.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"258 ","pages":"Article 107397"},"PeriodicalIF":4.8,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142425338","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}

However, demonstrating the biodiversity contributions of Indonesia's 382 identified potential OECMs (i.e., non-MPA areas, governed and managed, and likely contributing to biodiversity conservation) poses a challenge due to the absence of national monitoring systems outside MPAs. A spatial approach was used to provide an overview of the expected ecological contributions of potential OECMs upon formal recognition. Potential OECMs were, on average, five times smaller (26,838 ha) than MPAs (133,524 ha). Together with MPAs, they formed a denser conservation network, with many encompassing climate refugia reefs. Upon full recognition, potential OECMs could contribute to conserving &lt;1%, 12%, and 8% of the nation's mangroves, seagrass, and coral reef areas, respectively. Potential OECMs were restricted to coastal areas, and situated in various ecological contexts, including areas typically excluded from MPA designation, such as turbid reefs. Recognizing these OECMs could potentially add 10 million ha to national marine conservation areas. Collectively, MPAs and potential OECMs could contribute to conserving 13% of the nation's waters by 2030. Potential OECMs are effective locally and offer unique strengths, including diverse governance approaches, long-term presence, and potential socioeconomic benefits.

Annually repeated and acute human-induced disturbances were the primary threat to the intertidal seagrass species. Nevertheless, the subtidal seagrasses were primarily affected by unpredictable summer MHWs as well as gradual rising water temperatures, with MHWs causing more dramatic alterations in the coastal seagrass ecosystems compared to gradual SST rising. The continuous decline of seagrasses due to natural and human-induced disturbances will alter the structure of shallow coastal ecosystems, leading to significant changes in the ecosystem services they provide.
