Indonesia, through its Blue Economy Roadmap, integrates this concept into its national economic growth objectives. Although currently overlooked, an essential component of this strategy is successfully integrating widely practiced traditional community-based fisheries management systems like the Sasi Laut of Eastern Indonesia into the national blue economy strategy. Through a systematic review of literature, laws, regulations, and policies, this research aims to provide insights on how to promote effective integration of Sasi Laut and the Indonesian blue economy plan by (1) synthesizing Sasi Laut’s reported fisheries, conservation, livelihood, and other socio-economic outcomes and evaluating whether they are aligned with Indonesia’s blue economy objectives; (2) identifying policy instruments that could facilitate the integration of Sasi Laut and the blue economy; and (3) examining how Sasi Laut and the blue economy co-promote equitable and sustainable growth in social, economic, and environmental areas. Our results show aligned socioeconomic and ecological outcomes of Sasi Laut and the blue economy, signifying the important role of Indigenous knowledge systems like Sasi Laut in achieving Indonesia’s blue economy goals. Linking existing policies in support of the blue economy and traditional community-based fisheries management practices and active engagement and collaboration of various stakeholders, including Indigenous community members, local governments, and the national government, can help formalize and legitimize the role of the Indigenous knowledge system in Indonesia’s blue economy.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"187 ","pages":"Article 107032"},"PeriodicalIF":3.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145996179","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 article examines the case of Türkiye, a middle-income country with extensive coastlines and increasing exposure to climate risks, to explore how marine and climate governance interact in practice. Drawing on 22 semi-structured interviews with experts from government, civil society, and academia, the study applies thematic analysis to identify six interrelated challenges: (1) the gap between legal frameworks and implementation, (2) crisis-based governance, (3) institutional fragmentation and coordination deficits, (4) dependence on European Union funding and external alignment, (5) societal indifference and limited marine literacy, and (6) the contested discourse of the blue economy. The findings demonstrate that although Türkiye has adopted robust legal instruments and aligned with EU standards, enforcement and institutional integration remain weak. Governance is often reactive, fragmented, and externally driven, with limited societal demand for ambitious reforms. These dynamics reflect broader patterns in global marine-climate governance but are compounded by Türkiye’s context specific political and institutional constraints. The article argues that bridging the persistent policy-practice gap will require stronger institutional coordination, investments in capacity and literacy, and reframing the blue economy as a vehicle for climate adaptation and mitigation rather than narrow economic growth.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"186 ","pages":"Article 107013"},"PeriodicalIF":3.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145792117","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 paper seeks to address this gap by analyzing association of legitimacy with five such factors, based on the sample of 567 fishers from Croatia, which include large scale, small scale, subsistence, and recreational fishers. The analysis revealed a weak positive association between formal communication and compliance, while informal communication showed no significant relationship. Interaction with non-compliant fishers had a weak negative effect on legitimacy. Trust in fisheries administration and enforcement agencies was moderately and positively associated with legitimacy, while trust in NGOs showed no significant link. Trust in scientific institutions had a weak positive association, economic vulnerability a weak negative association, and professionalization a moderate positive relationship with legitimacy. Four hypotheses were tested using Kendall's tau, an ordinal bivariate correlation measure, while interaction with non-compliant fishers was tested separately using OLS regression. Overall, the results demonstrate that legitimacy emerges from the interplay of social and institutional structures rather than from regulatory design alone, underscoring the need for governance approaches that are adaptive, trust-building, and sensitive to sectoral differences.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"186 ","pages":"Article 107022"},"PeriodicalIF":3.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841920","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}

The revised MEPL fosters compliance initiatives within maritime corporations in three ways: increase in relative prohibitions and precautionary obligations; enhancing public supervision through mechanisms like information disclosure; and optimizing the liability mechanisms by integrating both the deterrence of penalties and the necessity for post-violation environmental restoration. These strategies aim to activate market dynamics in marine environmental protection by balancing the deterrence of legal liabilities with the discretion of corporation compliance. In the new era of the revised MEPL, the legal enforcement system may also be adjusted with these changes, shifting from an administration centered approach to one driven by civil litigation and corporate autonomous compliance. Under the current legal enforcement system, the construction of maritime corporate compliance in China encompasses five aspects: organizational structure, system design, internal management, information disclosure, and supervision and assessment.

Results from this study show that Kenya’s Blue Carbon Ecosystems (BCEs), particularly mangroves and seagrasses, are declining at alarming rates of 0.57 % and 0.26 % annually, respectively, with projections showing that, without intervention, mangrove cover could decrease by 15.8 % by 2050, releasing approximately 55.3 MtCO₂e. This decline underscores the urgent need for strong data collection and enhanced policy frameworks to enable meaningful BCE integration into climate strategies. Management interventions could mitigate these losses, boosting mangrove cover by 4 % above 2020 levels and reducing carbon losses by 67 % compared to a business-as-usual scenario. Furthermore, such interventions yield substantial economic return up to five times the cost for mangroves and three times for seagrasses highlighting the economic and environmental imperative of these measures.
