Vulnerability assessments have been carried out along several coastal zones across the world. These assessments help coastal scientists, engineers, and policymakers prepare plans and devise mitigation measures to safeguard the environment and coastal population against climate change and coastal hazard impacts. The present study evaluates the vulnerability of the Kasaragod coast in Kerala, the west coast of India, due to sea-level rise. Eleven variables, viz. relative sea-level change, mean significant wave height, tidal range, geomorphology, shoreline change rate, regional elevation, coastal slope, population, road/railway networks, tourist sites and land use/land cover are considered in the estimation of the Coastal Vulnerability Index (CVI). The resulting CVI values were categorized into low, moderate, high and very high vulnerability classes. Based on this classification, 41.33% of the Kasaragod sub-district and 13.26% of the Hosdurg sub-district fall under the ‘very high’ vulnerability category. A significant decrease in vulnerability was observed along the Kasaragod sub-district when socioeconomic variables were excluded from the CVI calculation. However, in the Hosdurg sub-district exclusion of the socioeconomic variables led to increased vulnerability along the coast. The vulnerability maps developed in this study provide a crucial tool for identifying highly vulnerable coastal stretches and guiding effective strategies to safeguard the Kasaragod coast and its communities.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00096-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145729596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the mechanisms by which these factors affect sediment grain size and shape distribution patterns is significant for ecological disaster mitigation and restoration of sandy coastlines. This study examines sediment samples collected from beaches in Western Guangdong, impacted by HPAE, two days and six days after the landfall of Typhoon “Chaba” (No. 2203). We analyze grain size parameters (mean size, sorting coefficient, skewness, and kurtosis) and shape parameters (sphericity, aspect ratio, convexity, circularity, symmetry), focusing on their characteristic values and spatial distribution patterns, as well as the underlying reasons for their similarities and differences. The results indicate that: (1) From two to six days post-typhoon, sediments on the affected beaches near the shore become coarser and less well-sorted, while sediments in the middle region become finer and better sorted. On the unaffected beaches, sediments near the shore become coarser, and those further offshore become finer, with no consistent pattern in sorting coefficient; (2) Landward sediments of the affected beaches exhibit a shift towards a more flattened shape, whereas sediments on the unaffected beaches trend towards a more rounded shape; (3) The correlation between the mean size, kurtosis, and grain shape parameters of the affected beaches weakens, while the correlation between the sorting coefficient and skewness strengthens. In contrast, the unaffected beaches exhibits the opposite trends. This study provides a case for understanding the impact mechanisms of sediment grain size and shape distribution under the combined influence of storms and HPAE. The findings contribute to a deeper understanding of sediment dynamics and the role of marine aquaculture in shaping sandy coastal geomorphology.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00103-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach was qualitative, and the methodology consisted of conducting open interviews with key actors to inquire about the perceived challenges to developing a marine energy project. The results show that the main perceived limitations are social, highlighting the resistance of various groups towards external projects. The resistance to changes in the environment results from previous experiences where the project promoters neither informed adequately the population about the practice of conducting research in the area nor shared the results and did not consider the participation of local actors. </p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00102-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On December 8, 2024, a landslide occurred on the southern slope of the Black Sea Coastal Highway near the Kıyıcık locality in the Arhavi district (Artvin, Türkiye). This landslide resulted in the loss of four lives and led to the temporary closure of the Black Sea Coastal Highway, which is of both national and international importance. This study aims to investigate the role of the Black Sea Coastal Road construction in triggering the Kıyıcık landslide. The research utilizes historical aerial photographs, high-resolution drone imagery obtained after the landslide, a 1:25,000 scale topographic map, and climate records from 1962 to 2022. X-ray diffraction (XRD) analysis was conducted to determine the mineral composition of the landslide mass, and spatial analyses were performed using Remote Sensing and Geographic Information System (GIS) technologies. The weathering effect of marine moisture and wind on the narrow-high coastal slope, and the erosion effect of heavy waves in stormy weather overtopping the road platform and reaching the slope are natural processes. The landslide mass comprises saprolite and lateritic regolith—products of the chemical weathering of mafic volcanic rocks. Road construction and quarrying operations have increased slope steepness, fracture density in the mafic volcanic rocks, and the intensity of chemical weathering processes. A total of 244.4 kg/m² of rainfall and infiltration between November 16 and 29, 2024, caused water accumulation in the loose regolith, increasing the static load and triggering a translational earth landslide. Tension cracks and fissures observed in the area indicate that the landslide remains active, highlighting the need for further risk mitigation measures.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00104-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Private buy-in and a whole-of-society approach is necessary to catalyze conservation. However, the involvement of diverse stakeholders begs the question: is conservation their true aim? Or has the commodification of carbon formed a disconnect between monetization and protection of BC ecosystems? In this paper, we present a conceptual link among stakeholders of BC projects and their roles across the project stages, synthesized from semi-structured interviews among actors within the BC credit ecosystem. Thirteen stakeholder categories are identified, with involvement spanning eight project stages from pre-feasibility studies to carbon credit retirement. Stakeholders closer to the supply-side of credits are more aware of conservation but need further awareness of the carbon credit cycle and vice versa for the demand-side. Overall, our findings indicate that conservation is secondary to commodification for most stakeholders. The project developer is the main actor that interacts with and is cognizant of the roles of other stakeholders, thereby having decision-making power in steering participation levels of other stakeholders. It became apparent that the project developer has broad-reaching consequences over the outcomes of the carbon project, implying that their perceptions and receptions regarding commodification versus conservation matters the most. We put forth the following recommendations for better governance of BC projects, amongst others: establishment of nationwide legal frameworks, improved participation of local communities, and institutional accreditation of stakeholders.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00105-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the key oceanic parameters, significant wave height is of particular importance due to its direct impact on marine operations. Traditional numerical simulations, while effective, require precise boundary conditions and substantial computational resources, often leading to long processing times. In contrast, deep learning approaches, leveraging powerful neural networks, have gained increasing attention for their ability to generalize and model complex, nonlinear relationships in data. However, current deep learning-based predictive models still face challenges regarding prediction accuracy and generalizability, particularly over extended forecast periods. To address these challenges, we propose an innovative predictive framework, VMD-Informer, which combines deep learning techniques with signal processing methods to improve the accuracy of significant wave height predictions over long forecasting horizons. The framework utilizes the Variational Mode Decomposition (VMD) method to decompose wave signal data during the preprocessing stage, enhancing both processing efficiency and prediction accuracy. The model construction incorporates the Informer model, which is specifically designed to ensure high accuracy across multi-step long-term time series predictions. Using data from NOAA's global buoy station 46,078, covering the years 2018–2019, our experiments demonstrate that the VMD-Informer model outperforms traditional machine learning models, particularly in predicting significant wave height for longer forecast intervals. These results highlight the potential of the VMD-Informer approach for advancing the accuracy of long-term oceanic weather predictions, providing valuable insights for marine forecasting systems.</p></div>","PeriodicalId":100098,"journal":{"name":"Anthropocene Coasts","volume":"8 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44218-025-00100-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144810787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
