With rising sea levels, coastal cities are expected to adapt to flooding and changing shorelines in the coming decades. With a growing interest in participatory planning and coastal management, it is key to develop new platforms to involve communities, decision makers and scientists alike in debates about climate adaptation. This article discusses the untapped power of speculative design in allowing society to envision future scenarios of climate adaptation and coastal protection. We draw on the experiences of the project “Adapting Waterfronts: Postcards from the Future, Singapore 2122” to interrogate how speculative visions about the future of waterfronts can support resilience building. The project consists of an exhibition, a virtual reality tour and a subsequent workshop, which provided opportunities for collective discussions on climate change adaptation. Exploring multiple types of knowledge, such as historic archives and scientific projections about sea-level rise, the project constructs new narratives about the political, social and biophysical aspects of coastal management. We discuss how the approach contributes to important debates in coastal management, including how it can (i) bridge historic barriers between different disciplines that are involved in urban planning and coastal management, (ii) foster speculative thinking through the use of augmented reality and (iii) reshape the relationship between researchers and society. This exploration of speculative futures – and the visualization of their implications in the city – has the potential to reshape how we conceptualize, analyse, and design coastal landscapes. Building on these experiences, we highlight gaps and important questions for similar projects aiming to promote scientific communication and education on coastal management strategies. We propose future lines of investigation on how speculative projects can offer opportunities for diverse audiences to connect with the science of climate change and, in doing so, promote collective debates on the topics of climate adaptation and coastal management.

The present study provides the first comprehensive assessment of the distribution of heavy metals (Al, Fe, Mn, Co, Ba, Zn, Cr, Ni, As, Pb, Cd) in surface seawater of Al Hoceima Bay, Mediterranean Sea, Morocco, over an annual cycle. Water samples were collected in autumn 2022, winter, spring, and summer 2023 from fifteen sectors covering the entire bay. The analysis involved descriptive analysis, correlation matrices, PCA, and Cluster analysis. Concentrations of Pb and Cd were below detection limits, while Cr and Zn concentrations were below saltwater aquatic life preservation standards. However, As and Ni concentrations reached 49.55 μg/L and 12.71 μg/L respectively during autumn 2022 and summer 2023, exceeding international standards. The HPI indices, calculated using As, Cr, Ni, and Zn concentrations, indicated poor seawater quality during winter (HPI = 69.52) and spring (HPI = 75.08), and totally inadequate quality with likely adverse health effects during autumn (HPI = 114.64) and summer (HPI = 116.79). The study recommends continuous monitoring and integrated management to preserve the bay's biodiversity and ensure future sustainability.

本研究首次全面评估了摩洛哥地中海胡塞马湾表层海水中重金属（Al、Fe、Mn、Co、Ba、Zn、Cr、Ni、As、Pb、Cd）的年周期分布情况。2022 年秋季、冬季、春季和 2023 年夏季，从覆盖整个海湾的 15 个区域采集了水样。分析包括描述性分析、相关矩阵、PCA 和聚类分析。铅和镉的浓度低于检测限，铬和锌的浓度低于海水水生生物保护标准。然而，在 2022 年秋季和 2023 年夏季，砷和镍的浓度分别达到 49.55 μg/L 和 12.71 μg/L，超过了国际标准。利用砷、铬、镍和锌浓度计算得出的 HPI 指数表明，冬季（HPI = 69.52）和春季（HPI = 75.08）海水质量较差，而秋季（HPI = 114.64）和夏季（HPI = 116.79）海水质量完全不合格，可能对健康产生不利影响。研究建议持续监测和综合管理，以保护海湾的生物多样性，确保未来的可持续发展。

Salt marshes are important blue carbon ecosystems, demonstrating significantly higher rates of organic carbon (OC) burial than terrestrial forests, thus playing a crucial role in mitigating global warming. However, these ecosystems are inherently fragile and vulnerable to degradation due to a variety of environmental stressors. An accurate assessment of the carbon sink capacity of salt marshes requires a comprehensive evaluation of OC burial and OC loss. Previous studies have often focused on quantifying OC loss roughly at large scale, while there has been less discussion about adequately addressing the geomorphological processes that drive such losses at finer regional scale. In this study, we investigate OC loss due to edge erosion in the salt marshes of Jiangsu, China, utilizing an integrated approach involving field surveys, remote sensing, and geochemical analyses. The results indicate that soil erosion is the predominant mechanism of OC loss. Furthermore, OC loss within sediments is principally determined by the erosion height and the OC content. The study also finds that autochthonous OC is more susceptible to decomposition and remineralization than allochthonous OC. From 2014 to 2021, the annual OC loss in Yancheng, Jiangsu Province, offset approximately 32 % of the OC sequestration. These findings aim to enhance understanding of OC dynamics in eroded salt marshes and emphasize the necessity for targeted management strategies to maintain the long-term carbon sequestration potential of these critical ecosystems.

The narrative surrounding coastal and marine conservation has largely focused on ecosystem services, viewing nature as a provider of benefits, to shape management practices worldwide. However, there has been a lack of emphasis on the bidirectional relationship between coastal communities and these ecosystems. This includes the Cultural Ecosystem Services (CES) or non-material values they encompass, namely how local populations interact with, perceive, and sustain these coastal seascapes. The present study aimed to explore and understand the relevance of community perceptions for CES within Bhitarkanika Wildlife Sanctuary (BKWS) in Odisha. Employing a Public-Participatory Geographical Information System (PPGIS) approach, we engaged 119 local stakeholders to identify and evaluate non-material values associated with the landscape. The survey encompassed socio-demographic information, ecosystem services derived from different production landscapes, awareness about the landscape changes, and valuation of CES, including cultural disservices. The residents identified 59 locations depicting 6 landscape values. Using interpolation techniques, six maps were computed to spatially characterize the diverse CES perceived by coastal communities. Results highlighted the importance of non-material benefits, with religious and aesthetic values being particularly significant. Regression analysis indicated that factors such as age, gender, etc. significantly influenced the appreciation of non-material values. Hotspot analysis (Getis-Ord Gi∗) identified areas of concentrated CES across varied production landscapes. By aligning community priorities with ecological objectives, the study provides a model with replication potential for sustainable mangrove management that can contribute to coastal conservation and mangrove restoration goals by promoting the synergy of ecological resilience and cultural preservation in coastal governance.

The navigational safety of ships can be impacted by factors such as varying weather conditions, sea states, circadian rhythms and crew physical conditions at different times of the day. Despite numerous studies in the maritime accident field, systematic investigations on the heterogeneous characteristics of accident Risk Influential Factors (RIFs) across different watchkeeping periods remain limited. To address this gap, this study pioneers a multidimensional analysis framework which integrates an Enhanced Multilevel Association Rule Mining (EMARM) algorithm, the Weighted Influence Non-linear Gauge System (WINGS), the Total Adversarial Hasse Diagram Technology (TAHDT), and the Matrices Impacts Croises-Multiplication Appliance Classement (MICMAC). Firstly, the innovative EMARM algorithm is proposed to identify frequent itemsets and enhanced multilevel association rules between RIFs, i.e., at the state level and factor level. Secondly, the WINGS is established in a data-driven manner and employed to elucidate the causality among these RIFs, providing insight into their interactions. Thirdly, the improved TAHDT, a game theory-based method is utilized to establish hierarchical relationships between RIFs, revealing critical interdependencies and causal pathways. Finally, based on the driving forces and dependencies of RIFs, the MICMAC is applied to classify the RIFs and dig their roles within the system. The results indicate a significant heterogeneity in the critical RIFs across different watchkeeping periods, such differences highlight the unique needs of safety management strategies in each period. By clarifying the challenges, the proposed framework offers a new perspective for improving bridge resource management onboard and further contributing to reducing accident occurrences.

The need to cut carbon emissions has placed global ports in a strategic position regarding the fight against climate change. This paper reviews the challenges, technological innovations, and opportunities that face efforts to retool ports into low-carbon operation centers. Ports are significant contributors to greenhouse gas emissions through vessel-related activities and operational processes. Improved international legislation, including a plan of action put forward by the International Maritime Organization, shoreside power supply, alternative fuels, and other green technologies are major propellers to new port design changes. The paper calls for cooperation from all stakeholders, applies holistic methods of valuation through data envelopment analysis and life cycle assessment, and discusses integration with smart technologies. Case studies of leading global ports-including the European Union Green Ports Program and the Belt and Road Initiative-underline how the goal for a hub of innovation in sustainable maritime logistics can be attained. Global coordinated action, full policy support, and institutional collaboration at all levels can make this goal of carbon reduction targets achievable in a balance with economic growth and environmental responsibility.

Industrial intelligence has greatly propelled industrial development, while having a profound impact on the environment. This study, using data from 48 coastal cities in China and their local enterprises, employs a two-way fixed effects model to examine the impact and mechanisms of industrial intelligence on marine pollution. By integrating macro-level city data and micro-level enterprise data, this study innovatively reveals an inverted U-shaped relationship between industrial intelligence levels in coastal cities and marine pollution, which is primarily mediated by industrial energy optimization and economic development. Initially, more industrial intelligence may increase pollution, but after a certain point, it can help reduce it. Additionally, urban innovation capacity and environmental regulatory intensity play crucial roles in modulating this relationship, particularly through the adoption of clean technologies and enhanced pollution standards. Compared to previous studies, this paper firstly unveils the nonlinear relationship between industrial intelligence levels and marine pollution, as well as the specific mechanisms behind it, filling a gap in the existing literature. These findings provide compelling empirical evidence and policy insights for sustainable coastal management in developing economies, emphasizing the synergistic relationship between industrial intelligence and environmental protection, which offers empirical or theoretical support for achieving green transformation.

工业智能化在极大推动工业发展的同时，也对环境产生了深远影响。本研究利用中国 48 个沿海城市及其当地企业的数据，采用双向固定效应模型，考察了工业智能化对海洋污染的影响和机制。通过整合宏观层面的城市数据和微观层面的企业数据，本研究创新性地揭示了沿海城市工业智能化水平与海洋污染之间的倒 U 型关系，这种关系主要以工业能源优化和经济发展为中介。在初期，更多的工业智能化可能会增加污染，但在一定程度后，它可以帮助减少污染。此外，城市创新能力和环境监管强度在调节这种关系方面也发挥着至关重要的作用，特别是通过采用清洁技术和提高污染标准。与以往的研究相比，本文首次揭示了工业智能化水平与海洋污染之间的非线性关系及其背后的具体机制，填补了现有文献的空白。这些发现为发展中经济体的可持续沿海管理提供了令人信服的经验证据和政策启示，强调了工业智能与环境保护之间的协同关系，为实现绿色转型提供了经验或理论支持。

In Mexico, the marine finfish fishery is multi-specific, and its effort is directed to species of commercial interest. The snappers group stands out with the species Lutjanus peru, which is most valued in the Mexican Pacific Ocean. The snapper fishery lacks specific regulatory measures for its management and is threatened by overfishing and climate change. The impact of climate change is one of the main challenges for marine species and coastal communities whose livelihoods depend on fisheries presence and abundance. Predictions indicate a migration of tropical species to the poles, so it is crucial to generate scenarios that forecast future changes in these fishery resources and generate adaptation measures for the communities that depend on them. Our study aimed to evaluate climate change impacts on the snapper fishery through ecological niche modeling and habitat suitability models. We modeled the future distribution of L. peru for 2050 and 2100 under two climate change scenarios (SSP126 and SSP585) and analyzed the impact on the fisheries from distribution changes and the dependence of this resource by coastal communities according to official catch records in the fishery offices along the Mexican Pacific. The results show that in the worst scenario (SSP585 to 2100), the zones with the highest and moderate negative impacts are located in around 24 fishery offices where 68% of the catch and 72% of the income occur, increasing the vulnerability of fishing communities due to the reduction in catches and greater fishing effort to compensate for losses. However, most models indicate low and positive impacts, as an increase in the species’ presence is expected in the northern Mexican Pacific Ocean due to a temperature rise. When allocated appropriately, government subsidies can strengthen resilience of fishing communities, by prioritizing the most vulnerable communities and users. Subsidies should focus on eliminating poverty and hunger, decreasing inequality, and promoting mitigation and adaptation in the face of climate change impacts.

Maritime Spatial Planning (MSP) is a politically guided and stakeholder-driven process involving a range of actors (i.e., planners, stakeholders, scientists, and citizens). Theories of boundary objects offer a lens to understand how actors, in the context of decision and policy-making in organizations, can coordinate without consensus. This seems particularly relevant when institutions and communities are relatively young, and the body of knowledge is fragmented and fluid, such as in the case of MSP. A key question is whether, and how boundary objects can be intentionally designed and used to facilitate social and policy learning in such communities. In this research, the focus is on the use of the MSP Challenge serious games as a boundary object to facilitate learning in ‘Communities of Practice’ (CoP) around MSP. Data were collected through questionnaires of 62 MSP Challenge workshops between 2016 and 2020 with more than 1100 participants. Additionally, 33 interviews with key stakeholders were conducted. The findings show that the MSP Challenge is widely used for various goals and in various settings and that they are interpreted differently by different users. The success of the MSP Challenge relies on the boundary space in which it is implemented, taking into account discrepancies in learning due to variations in the backgrounds and attitudes of the participants towards the object, the activity, and the setting in which it is deployed.

Offshore renewable energy technologies are being tested and deployed around the world to mitigate climate change and to bring clean sustainable energy to remote locations. The trend is being led by the development of offshore wind, with energy from waves, tides, and large run of the river turbines also increasing. However, there are additional marine renewable energy technologies that will help to fill in gaps of availability and location for power production. These emerging technologies are generally less well known, including ocean thermal energy conversion, seawater air conditioning, power from salinity gradients, and floating solar photovoltaics (floatovoltaics). Coupled with each of these power production systems is the need for energy systems at sea to aid in storage and transport of the energy. There is little known about the potential environmental effects of these emerging technologies or undersea energy storage, or how they might best be managed. This paper describes the new technologies and explores the potential effects on the marine environment and wildlife and recommends approaches to their management.
