Summary: The flooding and erosion of mudflats at the Nigerian Transgressive Mahin coast requires prompt measures to prevent further damage. This study integrated electrical resistivity geophysical and geotechnical methods to investigate the subsurface materials. Correlations were made between the sediment's electrical resistivity and their geotechnical variables. The application of nature-based techniques is recommended for the long-term restoration and management of the Mahin mudflat.

Summary: This study examined the changes in the Transgressive Mahin mud coastline over the past 20 years using multispectral satellite images and Geographic Information System. The study revealed that the eastern sector lost more land area compared to other sectors due to erosion, while the western sector experienced some accretion. Based on these findings, it is predicted that a significant amount of land could be lost in the future if coastal challenges are not addressed promptly.

Summary: Estuaries, as highly productive ecosystems, have attracted migrants and faced degradation due to human activities. This study analysed the changes in three major river estuaries in Ghana and revealed the impact of coastal flooding, erosion, and anthropogenic activities on land use/cover dynamics. Mangrove reforestation interventions were found to recover vegetation areas. Integrated coastal zone management is crucial for the sustainability of the environment and local livelihoods.

Summary: Spatially and thematically detailed land use maps are crucial for studying and managing populated mountain regions. A new highly detailed land use/land cover map for the European Alpine Region was presented, with a resolution of up to 5 m and a temporal extent from 2015 to 2020. By aggregating 15 high-resolution layers, 65 land use/cover classes were identified, resulting in an overall map accuracy of 88.8%. The map's high thematic and spatial detail allows easy customization for research and management purposes, catering to a wide range of applications.

Summary: This study investigates the effect of land use and land cover uncertainty on permafrost simulation in the Tibetan Plateau. The results show that land cover has a greater impact on soil temperature simulations in regions with greater land use inconsistency. It is important to increase the model plant function types and carefully select land use and land cover products in order to improve the simulation performance of land-surface models in permafrost regions.

Summary: Land-use land-cover (LULC) change is a significant threat to biodiversity and ecosystems integrity, necessitating the generation of accurate LULC maps. However, the lack of uncertainty quantification in current methods has limited their effectiveness. This article proposes the use of conformal statistics to determine pixel-level uncertainty, which is computationally efficient, statistically rigorous, and applicable to any classification algorithm. Simulation and analysis results demonstrate the potential of this approach in guiding data collection and effectively communicating uncertainty to users.

Summary: The study observed a decrease in plantation, mangrove swamp, and agricultural land areas since 2000, while an increase in sand beaches, waterlogged areas, mudflats, rivers, and agriculture areas. The NDVI values for mangrove forests and plantations decreased, while river, aquaculture, agricultural, and open scrub areas had higher values. The land surface temperature increase was highest over settlements, followed by sand beaches, mudflats, aquaculture, mangrove forests, rivers, plantations, waterlogged areas, and agricultural fields.

Summary: This study estimated the global biophysical temperature effects of LULCC using CMIP6 climate models and found a historical global warming effect of LULCC at a rate of 0.0025 degrees C/century. Forested/non-forested secondary land, urban land, and cropland have contributed over 70% to LULCC's temperature effect, with land transitions and land management also playing significant roles in the climate impact.

Summary: This study developed a practical framework to automatically update existing land use/land cover (LULC) products and bridge the gap between remote sensing classification results and land survey data. The updated LULC maps accurately reflect recent changes and maintain continuity with previous products. Additionally, a statistical space allocation method was proposed to optimize the maps and increase their correlation with land survey statistics.

Summary: This study investigates the properties of mudflats along the Mahin coast of southwestern Nigeria, and finds that the mudflats have high plasticity, high cohesion, and are overconsolidated. The physical and mechanical properties of the sediments are influenced by their chemistry and mineralogical composition, and estuarine dynamics play a key role in recent sediment transport along the mudflats.

Summary: Regular monitoring of coastal areas is crucial for mitigating erosive disasters. The erosion along Ghana's coastline, like other countries in the Gulf of Guinea, is a persistent issue. This study used multiple data collection methods, including drones, cameras, satellite images, and a dumpy level, to assess shoreline changes in Elmina Bay, Ghana. The results identified the causes and areas of erosion at a fine scale and highlighted the effectiveness of local video cameras and drones for monitoring shoreline changes. Satellite imagery, although a potential alternative, has limitations in temporal resolution for detecting daily or event-based beach changes.

Summary: Regular and long-term monitoring of coastal areas is crucial to mitigate the impacts of climate and human-driven hazards. In Africa, where observations are generally scarce, a network of low-cost, multi-variable shore-based video camera systems has been established to share data, methods, and results, aiming to implement an integrated coastal management policy. This network has provided new insights into the evolution of African beaches, waves, sea level impacts, and is a platform for interdisciplinary observations in resources and ecology, erosion and flooding, early warning systems, and science-based coastal infrastructure management.

Summary: Coastal areas are experiencing increased vulnerability to frequent and severe environmental disasters due to climate change. Understanding societal perceptions of risk and concerns related to hazards can contribute to the development of adaptive strategies and management preferences. This study examined how households in the Anlo Beach fishing community in Ghana perceived and responded to coastal hazards. Coastal erosion and salinization ranked as the most important risks in the area. The findings highlight the need for education and awareness campaigns to promote self-mitigation actions and the government's reconsideration of relocation plans.

Summary: Plastic marine debris has been found to have a negative impact on marine organisms and the environment. This study investigated the presence of microplastics in the Nigerian Lagos Lagoon ecosystem and found that they were present in the water, sediment, and certain fish species. The contamination was primarily due to plastic debris from recreational, industrial, and domestic waste. Urgent measures are needed to protect Nigeria's coastal and marine ecosystems from plastic pollution.

Summary: Estuaries and coastal areas are undergoing rapid changes due to climate change and sea level rise. This research presents a salinity transport model for Biscayne Bay and investigates the potential impacts of altered precipitation, increased salinity/temperature, and sea level rise on bay salinity. The findings suggest that current restoration plans may not be sufficient to maintain current salinity conditions, and management measures such as urban greening, artificial groundwater recharge, and water consumption reduction should be considered.

Summary: The study shows that spatiotemporal simulation modeling is an effective tool for investigating management options in ecosystem-based fisheries management. It demonstrates that fisheries restricted areas can help rebuild the biomass of exploited stocks, but their effectiveness depends on the size and location of the areas. The study also suggests that a parallel reduction in total fishing effort is necessary to achieve the highest benefits of protection.
