Summary: The rising sea level and increasing tropical storm frequency caused by climate change are threatening small Island economies that rely on their coastal environments and resources. Monitoring the evolution trends of shorelines is considered essential to improve the resilience of Island states due to the high socio-economic and environmental values of tropical sandy beaches.

Summary: Shoreline change analysis is crucial for evaluating coastal exposure to erosion hazards, particularly for vulnerable habitats like coastal wetlands. The increasing availability of high-resolution satellite imagery and advancements in analysis techniques support the implementation of these data into shoreline monitoring, allowing for a wider spatial scale-range and cost reduction in labor-intensive practices.

Summary: The impact of shoreline recession on the transport of nitrogen and phosphorus in a nearshore aquifer and their discharge to coastal waters is evaluated. The findings show that shoreline recession increases phosphorus fluxes to the lake, while nitrogen fluxes are influenced by specific geochemical conditions near the sediment-water interface.

Summary: The Earth's changing climate is causing ice sheets and glaciers to melt, leading to rising coastal hazards and sea levels. Coastal areas with a total population of over 300 million people, including 20 megacities, are among the most vulnerable to climate change impacts. Sea-level rise, combined with other factors, could lead to the displacement of hundreds of millions of people, with significant global impacts.

Summary: This research aims to develop a Coastal Vulnerability Index (CVI) using remote sensing and GIS approaches to assess the vulnerability of the coastal zone in Bali Province to sea-level rise. The study reveals that approximately 22% of the mapped shoreline is classified as being at very high vulnerability, and 26% of shoreline is at high vulnerability. The remaining shoreline is categorized as having moderate and low risk of coastal vulnerability.

Summary: This study examines the role of mangroves as coastal protective barriers in the face of sea-level rise. The results show that a significant portion of the shoreline is experiencing erosion, and further loss is expected by 2030. The study also emphasizes the economic losses and costs associated with shoreline changes and mangrove loss. Conservation policies and restoration efforts are necessary to safeguard the ecosystem-service co-benefits provided by mangrove forests.

Summary: This study was conducted in Phuket, which contributes 15% of the nation's GDP from tourism industry. Shoreline changes in beach areas were analyzed using the CoastSat open-source software and satellite imagery API. Future shoreline recession was projected based on field observation data and sea level rise scenarios. The study found mild erosion in eight locations from 2013 to 2021, with average shoreline change ranging from -4.10 to 5.47 m/year. The projection also indicated possible complete loss of 20 and 32 beaches under SSP1 2.6 and SSP5 8.5, respectively. Human activities such as coastal urbanization and development of structures along the coast were found to influence beach morphology. The study discusses the effectiveness of current coastal protection structures and proposes future management strategies.

Summary: This study aims to assess the situation, causes, and impacts of coastal erosion on selected communities in Lagos State, Nigeria. Through satellite image analysis and questionnaire surveys, it was found that there are significant differences in the extent and causes of coastal erosion in different regions, which have detrimental effects on the livelihoods and tourism industry of local communities. Moreover, these communities have a low resilience to coastal erosion, making them susceptible to the effects of climate change.

Summary: This paper evaluates the impact of erosion in a coastal zone of the active margin of Ecuador, using remote sensing images and a numerical model. The study indicates a net transport influenced by waves of 470m³/day, and categorizes erosion threat levels as high (45%), medium (46%), and low (9%). Future scenarios show a continuous retreat of the coast, with the potential for collapse of the main coastal highway in Ecuador.

Summary: This study evaluates coastal erosion management strategies along the monsoon-dominated coastline of Terengganu, Malaysia by assessing the efficacy of coastal protection structures. The study finds that Terengganu is the most impacted region in Malaysia in terms of coastal erosion due to a higher frequency of storms and high wave energy during the northeast monsoon. The effectiveness of coastal defence structures is evaluated by analyzing historical shoreline positions using the Digital Shoreline Analysis System (DSAS).

Summary: Since the 1940's, rapid shoreline and dunefield changes have been ongoing at Salmon Hole in South Australia. The formation of a lagoon between the mainland/dune system and the offshore reef, combined with the breakthrough of the tombolo, has accelerated erosion processes at Salmon Hole. If current erosion rates continue, the entire system is likely to be fully eroded within the next 30 years.

Summary: This study examines morphological changes, erosion-sedimentation patterns, shoreline changes, and sediment accumulation on Sonadia Island in Southeast Bangladesh. The investigation reveals frequent and rapid modifications of the island's shoreline. Land use and cover changes, erosion, and sedimentation rates are analyzed from 1972 to 2021. High accumulation rates are attributed to various shoreline activities and natural factors.

Summary: Coastal dynamics are influenced by various natural and human processes. Studying past and future coastal behavior is crucial for effective coastal zone management. This study examined the 50-year shoreline evolution of the Catania coastal plain in Southern Italy, using satellite imagery and analytical tools. The findings highlight the significant impact of human activities on coastal changes and the importance of considering coastal morphology in forecasting shoreline positions.

Summary: The study suggests that the spring blooms of phytoplankton in the Arctic Ocean are highly dependent on sea-ice meltwater for horizontal mixing and maintaining the stratified upper ocean. When meltwater concentration is sufficient, it allows phytoplankton to be confined near the surface, exposed to enough sunlight for optimal growth. The findings support the central role of sea-ice meltwater in shaping the spatial patterns of Arctic phytoplankton blooms.

Summary: In this study, the authors explore the formation of regular patterns in ecosystems and geomorphology, proposing competition as a complementary mechanism contributing to spatial self-organization. By studying the patterned landscape of Big Cypress National Preserve in South Florida, they demonstrate that competition among pattern elements, rather than scale-dependent feedback, leads to spatial regularity such as evenly spaced limestone depressions.

Summary: The study shows that discontinuous barrier retreat is prevalent when the storm return period and characteristic time scale of dune growth are of similar magnitudes. Under conditions of greater storm intensity, discontinuous retreat becomes the dominant behavior. Alternatively, higher rates of sea-level rise decrease the overall likelihood of discontinuous retreat in favor of continuous transgression.

Summary: The dynamics and morphological evolution of deltas and their channel networks are influenced by water and sediment discharge, vegetation, and other factors. The study explores how water and sediment discharge affect delta evolution and how vegetation stabilizes the channel network. The findings provide insights into avulsion dynamics and the role of vegetation in channel stability under different discharge conditions.

Summary: The asymmetry of wave climates affects delta avulsion behaviors and shape evolution. Increasing wave-climate asymmetry reduces the curvature of updrift delta flanks and increases the possibility of downdrift locations. However, under certain conditions, wave climates may inhibit downdrift avulsions.
