Simultaneously, marine fisheries exacerbate climate change by emitting greenhouse gases through fuel combustion and electricity consumption. This article reviews 142 studies on the bidirectional interactions between climate change and marine fisheries (ICCMF), utilizing bibliometric methods including co-occurrence network analysis, cluster analysis, and conceptual framework analysis to identify research trends, challenges, and gaps. The bibliometric analysis reveals an explosive growth in publications and patents related to ICCMF since 2020. The key themes in ICCMF research encompass: (a) the impacts of climate change on marine fisheries, (b) the contribution of marine fisheries to climate change, (c) stakeholder perceptions and responses to climate change, and (d) adaptive management strategies for climate-resilient fisheries. Notably, recent studies have increasingly focused on carbon emissions and carbon sinks in marine fishery industries, emphasizing the need for further research into carbon reduction practices to mitigate climate change. This review identifies several challenges, including geographical disparities, knowledge inequality, \"parachute science\" and \"helicopter research,\" issues with data quality and management, and inadequate capacity to adapt to climate change. Key research gaps include the limited representation of perspectives from the Global South, the absence of sustained partnerships, imbalances in research collaboration, restricted data accessibility and reliability, and an inadequate understanding of fisheries' carbon emissions. This review provides valuable insights for researchers, policymakers, and stakeholders, highlighting the need for strategic management approaches to mitigate adverse impacts and promote marine ecosystem sustainability.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"259 ","pages":"Article 107479"},"PeriodicalIF":4.8,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to analyse the stakeholders' perception on uses and ecosystem services in the Cíes Islands archipelago, located in the National Park of the Galician Atlantic Islands. Results from semi-structured questionnaires conducted with different stakeholders, indicated that landscape values and marine research were the most valued ecosystem services, although slight differences were found between fishers and other sectors. The activities exerting the highest pressure on the protected area were fishing and tourism. Conflicts were mainly associated with the co-existence of activities within the MPA, potentially threatening conservation goals.

This can significantly increase the enthusiasm of local governments, enterprises, and others for protecting and restoring the marine environment. However, owing to the characteristics of public goods and the externalities of blue carbon, it is difficult to price them through the supply and demand relationship of the traditional market. This paper focuses on how to price blue carbon under government policies and market uncertainties to encourage investors to engage in blue carbon projects involving the ecological protection and restoration of coastal wetlands. First, a universal blue carbon pricing model is established via the real option approach. The mangrove blue carbon project in Zhanjiang, Guangdong, was used as a case study to evaluate the price of mangrove blue carbon. This research provides technical support for the formation of blue carbon prices, and this method can be used not only to promote the protection and restoration of the marine environment but also to optimize the supply of blue carbon, fully leveraging its role in addressing climate change.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"259 ","pages":"Article 107475"},"PeriodicalIF":4.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660086","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}

Firstly, this paper uses the Supply Chain Network Model and the Optimization Model to theoretically analyze the impact of this incident. Secondly, the Global Trade Analysis Project (GTAP) Model is employed to analyze the impact of the crisis on China. At the same time, it also explains whether the impact of the incident can be alleviated by using CHINA RAILWAY Express (CR Express). Finally, this paper compares the upward pressure changes of domestic commodity prices in China, Germany, France, Netherlands and Italy before and after the adoption of CR Express. The results of the study are as follows. (1) The outbreak of the Red Sea Waterway Crisis has a great negative impact on China's macro economy. When China switches to the use of CR Express, the impact on China's GDP and terms of trade is reduced. (2) The outbreak of the Red Sea Waterway Crisis has a greater impact on China's import trade than on its export trade. (3) The outbreak of the Red Sea Waterway Crisis has a great negative impact on China's textile and clothing industry and electronic equipment industry. (4) CR Express can ease the upward pressure of domestic commodity prices.

In this study, we assessed ecosystem carbon (EC) density levels in <em>Sonneratia apetala</em> planted coastal ecosystems in the Char Kukri-Mukri and Montaz mangrove reserves in the south-central Bangladesh. Using 48 representative plots from four stand ages (8–32 years), carbon density changes in trees and soil (0–15 and 15–30 cm) were evaluated. Results showed significant differences in vegetation carbon (VC) density, soil organic carbon (SOC) concentration, SOC density, and EC density among different stand ages, soil depths and mangroves. The increased EC density in Char Kukri Mukri (12.21 t ha⁻¹ yr⁻¹) and in Char Montaj (12.62 t ha⁻¹ yr⁻¹) with advancing stand ages (year-8 to year-32) provides empirical evidence of the effectiveness of afforestation in enhancing EC density in <em>S. apetala</em> planted mangroves. Regardless of stand age, the higher SOC density found in the upper soil layer (51 t ha⁻¹ in year-32 stand) compared to the lower layer (38 t ha⁻¹ in year-32 stand) in both mangroves highlights that the majority of soil carbon is concentrated in the top 15 cm of the forest floor.
