Effective governance of small-scale, multi-species coral reef fisheries requires integrating diverse knowledge systems while addressing critical data gaps. Yet, despite increasing calls for participatory approaches, existing species prioritisation frameworks remain largely expert-driven, with limited application in data-limited, multi-species contexts and minimal involvement of fishers in shaping research agendas. This gap reduces the legitimacy, feasibility, and uptake of management-oriented research. We propose a structured, participatory framework for species prioritisation that strategically addresses knowledge gaps to support future research and management. The framework combines three criteria – species vulnerability, operational feasibility, and fishers’ priorities – through a three-phase, stakeholder-inclusive process. We apply it to a French Polynesian coral reef fishery, a context marked by ecological diversity, limited data, and ongoing transitions toward participatory governance. Results highlight the governance challenges inherent to species prioritisation, including ensuring broad fisher representation, balancing power dynamics, and managing trade-offs between ecological objectives and feasibility constraints. While the process successfully integrated fishers’ knowledge into decision-making, it also underscored the resource demands of participatory engagement and the need for adaptive monitoring to prevent effort displacement or the marginalisation of non-prioritised species. Beyond French Polynesia, the framework’s transferability depends on regional conditions: it may be facilitated in island settings with strong community ties but will require broader representation mechanisms in more densely populated contexts. By embedding participation at the earliest stages of research design, this framework contributes to operationalising inclusive, knowledge-based fisheries governance and offers a replicable tool for data-limited, multi-species fisheries seeking to balance ecological sustainability, socio-economic realities, and governance legitimacy.

Mangrove ecosystems are increasingly threatened due to a combination of anthropogenic and natural pressures. These pressures, including oil pollution, unsustainable harvesting, deforestation, and urbanization, are exacerbated by environmental challenges such as invasive species and climate change. Despite the global ecological relevance and socioeconomic importance at scale, mangrove ecosystems remain inadequately protected by existing policies in Nigeria. This study assesses the policy gaps in the management of mangroves in Nigeria, highlighting the shortcomings in enforcement, community engagement, and integrated management approaches. Key findings reveal that oil spills have severely degraded the mangrove ecosystems, leading to biodiversity loss, reduced fishery productivity, and jeopardised carbon sequestration capabilities. Deforestation driven by unsustainable logging, land conversion, and aquaculture further exacerbates habitat loss, while pollution from land-based agricultural runoff and plastic debris undermines mangrove health. Existing policy frameworks, such as the Nigeria’s Environmental Impact Assessment (EIA) Act and National Forestry Policy, lack specificity in addressing mangrove conservation challenges and suffer weak enforcement. Limited community involvement and insufficient research hinder the implementation of sustainable management strategies, while existing policies are adhoc. The study highlights the need for integrated coastal zone management (ICZM) frameworks, enhanced enforcement mechanisms, and the incorporation of mangrove-specific targets within existing policies such as the Nationally Determined Contributions (NDCs). Strengthening multi-stakeholder collaboration and leveraging international commitments are essential for bridging policy and implementation gaps. This comprehensive approach can ensure the sustainable management and restoration of degraded mangroves, safeguarding their ecological integrity and the livelihoods of dependent communities.

Different existing technologies for the decarbonisation of ports have been analysed applying a tool for decision making (DSS) specific for ports, based on a multicriteria system which has been validated by a multidisciplinary group of port experts, having taken into consideration economic, environmental, social and technological criteria, supporting port managers to establish a strategy and select the best technologies for the fulfilment of commitments of a port, in addition to be of use for the scientific and technological sectors when assessing different technologies. Along with the decision-making tool, a software tool has been developed, to analyse the potential of the different technologies and their feasibility using the case study of the Port of Vigo, by comparing different technologies from the four aforementioned perspectives, aiming to achieve the energy sovereignty of a port when facing future demands. The methodology in this case study was verified using operational data (Botana et al., 2023). The energy requirements were calculated and their potential provision through renewable resources was assessed, with the objective to achieve the complete decarbonisation of the port.
基于多学科港口专家小组验证的多标准系统，应用港口特定的决策工具（DSS）分析了港口脱碳的不同现有技术，考虑到经济，环境，社会和技术标准，支持港口管理者制定战略并选择最佳技术来履行港口的承诺。此外，还可用于科学和技术部门评估不同的技术。除了决策工具外，还开发了一个软件工具，以维戈港为例，通过从上述四个角度比较不同技术，分析不同技术的潜力及其可行性，旨在实现港口在面对未来需求时的能源主权。本案例研究中的方法使用运营数据进行了验证（Botana et al., 2023）。计算了能源需求，并评估了通过可再生资源提供能源的潜力，目标是实现港口的完全脱碳。

Public engagement by scientists has become imperative across the science-policy interface. Today, there are increasing calls for scientists to engage communities and policymakers as a pathway to incorporate social pluralism, many ways of knowing, and producing usable knowledge. Yet, there is a limited understanding of the strategies and attributes that can help scientists interact with other distinct publics in two-way conversations on a pressing issue such as climate change. Here, we examined via 28 semi-structured qualitative interviews, strategies and personal attributes of scientists and their practices that offer a pathway to transforming public engagement under climate change. We found that scientists use seven strategies and six personal attributes to engage distinct publics in two-way dialog and active and deep discussions on climate change. These strategies require scientists to foster connection with others, engage the public from the beginning, create safe spaces for dialogue, provide summaries for discussions, go beyond arms-length approaches, understand the context, and approach engagement as a partnership. The strategies also draw on attributes related to being open-minded and resilient, knowing your competencies and audiences, practicing reflexivity, and respecting alternative viewpoints. These findings and insights have implications for how scientists engage distinct publics in two-way dialogue by offering an evidence base to support practice change. They form a first step in informing the ability of scientists to navigate differences across settings and with questions of power and politics.

Marine Spatial Planning is typically a matter of national sovereignty, but growing cross-border marine activities are creating pressure for more coordinated transboundary approaches. However, such Transboundary Marine Spatial Planning (TMSP) efforts remain largely informal, temporary and voluntary, begging the question why more formal and enduring collaborations have struggled to materialize. This study aims to identify opportunities and barriers shaping the development and mode of collaboration of novel TMSP on the North Sea. A qualitative research methodology is adopted, combining a systematic literature review with an in-depth case study of the Greater North Sea Basin Initiative, based on participant observation. This initiative brings together nine North Sea countries to explore the creation of a regional platform for spatial integration of marine activities. The literature review identifies six categories that may function both as opportunities and barriers: resource availability, data and knowledge, the alignment of national institutional frameworks, (geo)political dynamics, existing transboundary relations and institutions, and stakeholder participation. The case study findings reveal that, while various opportunities legitimize and support the initiative’s development, key concerns – particularly over national sovereignty and institutional ambiguity of sea basin-level governance – limited the potential formality of collaboration. As a result, the initiative is evolving as an informal, voluntary platform for agenda-setting and early dialogue. The study concludes that although formal TMSP remains unlikely on the short-term, fostering informal collaboration already allows for more structured regional coordination as spatial and geopolitical tensions increase, while it may also be a stepping stone to possible future degrees of formalization.

The high demand for sea cucumber in Asian markets continues to motivate the expansion of this fishery around the world. A common pattern is a boom-and-bust trajectory, meaning rapid development at the outset, and a predictable collapse after a few years. In Mexico, temporary-well-paid processing jobs for women were created and sea cucumber fishers earned a good income, but both disappeared with the collapse of the fishery. In Thailand, sea cucumber has been harvested for centuries, and apparently the boom-and-bust phenomena occurred in different phases throughout history. The research objective was to explore the factors that determine the sea cucumber fishing dynamics in Thailand, and its gendered effects, as compared to Mexico. How does the gendered adaptation for depletion of sea cucumber differ between Mexico and Thailand? We aim to identify the coping and adaptation strategies taken by women to face the bust of the sea cucumber fishery. In Mexico, sea cucumber harvesting is men’s work, since it involves diving. In Thailand, it is gleaned, and women play a large role. Mexican fishers flocked to sea cucumber because they did not have as many options for well-paid employment, and women held mostly temporary-low-paying jobs, while in Thailand, employment opportunities are greater, men fish and women glean, and both also have access to other income-earning opportunities through tourism and agriculture. Currently the context in which sea cucumber is traded in Thailand provides ways to protection of marine resources, and women and men’s engagement followed different pathways in Mexico and Thailand.

Climate-driven changes in the marine environment are altering the distribution, abundance, and productivity of many commercially valuable fish and shellfish species. While many studies have focused on how these changes are affecting lives and livelihoods in fisheries dependent communities, less attention has been given to assessing the impact of climate change on fishing effort. This paper presents findings from a study that investigated lobster harvester perceptions of the impact of extreme weather-driven ocean conditions on fishing effort in Nova Scotia, Canada. Harvesters who fished in more exposed locations, reported that the number of fishing days that they had lost due to bad weather had increased over time. Our analysis shows that the number of fishing days lost is greatest in areas where harvesting occurs furthest from shore. Median wind speeds that prevented harvesters from fishing were a function of lobster fishing area and vessel size but ranged from approximately 45–65 km hr-1. This study provides insight into harvester use of ocean space and highlights how severe weather events arising from climate change can affect livelihoods in fishery dependent coastal communities.
气候驱动的海洋环境变化正在改变许多具有商业价值的鱼类和贝类物种的分布、丰度和生产力。虽然许多研究都集中在这些变化如何影响依赖渔业的社区的生活和生计，但很少有人关注评估气候变化对捕鱼努力的影响。本文介绍了一项研究的结果，该研究调查了加拿大新斯科舍省龙虾采集者对极端天气驱动的海洋条件对捕捞努力的影响的看法。在更多暴露地点捕鱼的收获者报告说，由于恶劣天气，他们损失的捕鱼日数随着时间的推移而增加。我们的分析表明，在离海岸最远的捕捞地区，损失的捕捞日数最多。妨碍捕捞者捕鱼的中位数风速是龙虾捕捞面积和船只大小的函数，但范围约为45-65 km / h。这项研究深入了解了海洋空间的收割机使用情况，并强调了气候变化引起的恶劣天气事件如何影响依赖渔业的沿海社区的生计。

<div><div>The rise of microplastics (MPs) and nanoplastics (NPs) in the environment and food systems alarms scientists, regulators, and the public. Effectively managing these pollutants requires an understanding of how different social groups perceive risks and engage with proposed solutions. Researching these perceptions is urgent in Costa Rica, which, despite its environmental leadership, lacks comprehensive regulations on MPs and NPs. This study presents findings from a national survey (n = 168) evaluating awareness, risk perception, behavioral intentions, trust in institutions, and support for regulatory measures regarding micro/nanoplastics. The survey targeted professionals in science, health, and engineering fields, representing a technically informed segment of the Costa Rican public. Accordingly, findings should be interpreted as <em>technically informed public perception</em> rather than general population opinion. Accordingly, findings reflect perceptions of a technically literate segment of the public and are not intended to be generalized to the national population. We explicitly call for probability-based, nationally representative surveys that prioritize rural, non-STEM, low-income, Indigenous, and coastal communities to validate and extend these patterns. Data were analyzed using descriptive statistics, cross-tabulations, and visualizations across 14 key questions. Findings show that 92.3 % of respondents were aware of MPs/NPs, and 88.7 % perceived them as a health risk. Regarding behavioral responses, 78.6 % expressed willingness to change personal consumption habits, while 76.2 % supported mandatory product labeling. Trust in governmental action was critically low, with only 3 % expressing confidence, 59.5 % expressing distrust, and 37.5 % expressing uncertainty. Moreover, 69 % had not noticed or were unsure about national initiatives on plastics governance. These percentages are non-overlapping indicators from different survey questions and therefore do not add to 100 %. However, together they reveal a coherent pattern of high awareness and concern, strong support for regulatory measures, and very low institutional trust. This indicates a motivated public perceiving a credibility gap in regulations. This research underscores the importance of public perception studies in shaping participatory environmental governance. Identifying trust gaps and behavioral thresholds can guide risk communication, labeling frameworks, and policy development. The findings reveal a governance deficit in plastic risk management, where high scientific awareness does not align with institutional credibility. Policy reform should engage the informed public as a strategic ally rather than a passive recipient of regulation. Policy reform should engage the informed public as a strategic ally while commissioning representative follow-up surveys across non-STEM and underserved populations to ensure equitable, evidence-based microplastic governance.

However, together they reveal a coherent pattern of high awareness and concern, strong support for regulatory measures, and very low institutional trust. This indicates a motivated public perceiving a credibility gap in regulations. This research underscores the importance of public perception studies in shaping participatory environmental governance. Identifying trust gaps and behavioral thresholds can guide risk communication, labeling frameworks, and policy development. The findings reveal a governance deficit in plastic risk management, where high scientific awareness does not align with institutional credibility. Policy reform should engage the informed public as a strategic ally rather than a passive recipient of regulation. Policy reform should engage the informed public as a strategic ally while commissioning representative follow-up surveys across non-STEM and underserved populations to ensure equitable, evidence-based microplastic governance.

The interactions between marine mammals and anthropogenic activities are of growing global concern, with increasing evidence highlighting the various ways these species are impacted by human actions. While these interactions have changedover time, many species still face threats, particularly from accidental entanglements in fisheries, like the king crab fishery, and from vesselcollisions, often resulting in death or serious injury. We have gathered information on these interactions in the Beagle Channel, spanning the past 43 years for fishing-related incidents and over 20 years for ship strikes. Although the frequency of interactions remains low, they have become more frequentin recent years, partly due to the recovery of marine mammal populations after the cessation of hunting, as well as the rise in marine activities. While fishing practices have not changed significantly, bycatch in king crab fishery remains a persistent risk, amplified by the increase of whales in the channel and potential conflicts with ship traffic. Our study highlights the need to strengthen the enforcement of regulations in the Beagle Channel, an area identified as high-risk for marine mammals, and advocates for the implementation of effective practices to mitigate bycatch, regulate marine traffic to reduce the risk of collisions, in orden toprotect marine mammal populations.

In the face of escalating climate-related challenges, transformative tourism experiences, such as marine-based tourism, have the potential to drive change, but few studies examine how tourism experiences motivate climate action. This study addressed this gap, investigating how marine-based tourism experiences influenced individual engagement with climate action. We conducted post-visit surveys of tourists (N = 436) who had visited an iconic marine tourism site – Lady Elliot Island Eco Resort, Great Barrier Reef (Australia). Surveys quantified visitor engagement in twelve types of activities during their visit (e.g. snorkelling, diving, guided island tours, educational activities, tree planting), subjective perceptions of their overall experiences (e.g. learning and reflection), and climate behaviours. We found that participating in a greater number of activities, rather than a particular activity type, had the strongest association with climate behavioural intentions. However, only a small proportion of visitors completing the survey could identify a specific action that they could take to mitigate climate change or support decarbonisation (e.g. reduce driving, petition for investing in renewables). This finding underscores a significant gap between motivation of Reef visitors to engage in climate actions and their procedural knowledge about available actions. Overcoming this gap will require tourism operators and those designing interpretation content to integrate climate-focused calls to action and strategies into marine tourism experiences. The study emphasises the importance of creating programs that offer consistent opportunities across diverse activities to bridge the psychological gap between threat awareness and engagement with effective climate actions. This work contributes to the growing literature on transformative tourism and offers practical implications for designing impactful climate experiences to support conservation of marine ecosystems.
