The Lagos State coastline is increasingly vulnerable to erosion, driven by both a dominant eastward longshore sediment transport and ongoing human interventions. Climate change, through rising sea levels and a changing wave climate, is expected to further influence shoreline dynamics in the coming decades. Understanding how these factors interact is crucial for supporting long-term coastal management along this coastline of major economic and social significance. This study investigates the impact of climate change on shoreline evolution over a 50-year timescale, focusing on sea level rise, changes in significant wave height, and changes in wave direction. The onedimensional shoreline evolution model ShorelineS was applied and calibrated using satellite derived historical shoreline data. Simulations were performed for a range of climate scenarios, allowing for a separate evaluation of the individual contributions of sea level rise, changing wave height, and changing wave direction to coastal erosion and accretion patterns. Longshore sediment transport is projected to increase by up to 20% by 2075 under extreme RCP8.5 scenarios. This intensification directly drives changes in shoreline dynamics, leading to amplified erosion in some areas and enhanced accretion in others. Projected shoreline retreat can reach up to 700 meters locally under baseline conditions (i.e., without climate change) by 2075. Climate change can further amplify these patterns, with shoreline retreat increasing by up to 10% in erosion-prone areas near coastal structures. In contrast, accretive zones show a more moderated response due to counteracting effects between sea level rise and wave-driven accretion. Wave direction changes were found to have the strongest localized impact on shoreline retreat near coastal structures, while the influence of wave height changes was less consistent and more variable along the coast. Sea level rise causes relatively uniform retreat along the entire coastline. The results provide spatially explicit projections of shoreline retreat and accretion, offering insights into areas most at risk. These findings support the development of targeted, adaptive coastal management strategies for Lagos State in the face of a changing climate.

Located in Suriname, the village of Ricanau Mofo faces a multitude of environmental challenges. This report delves into a comprehensive study that employed a multidisciplinary approach, leveraging the expertise of students from various backgrounds to address these pressing issues.

The most critical concern identified was the relentless erosion of the riverbank, forming an existential threat to the village. The report explores interventions for both riverbank and soil erosion. Building upon the previous year's sheet pile wall construction by van Dongen et al. (2023), the report evaluates its effectiveness and proposes potential improvements for natural shore protection. It presents an analysis of structural solutions like sheet pile walls and quay walls, alongside nature-based methods that promote vegetation growth. A multi-criteria analysis is employed to objectively evaluate the effectiveness and feasibility of each intervention.

Moving beyond the riverbank, the report investigates soil erosion in Ricanau Mofo's old center. To understand the water flow patterns, a hydrological analysis was conducted. This analysis incorporated field measurements, on-site observations, and existing scientific reports. By considering factors like clay content, vegetation cover, discharge, and slope, the study categorized different flow areas within the village center. This detailed analysis lead to the proposal of a combination of targeted interventions, including roof gutters, strategic vegetation planting, and channel improvements, all aimed at effectively addressing drainage issues and mitigating soil erosion.

Waste management emerged as another critical concern. The report sheds light on the impact of inadequate waste collection systems on hygiene and even the success of other implemented solutions. Recognizing the importance of community involvement, the report proposes a roadmap and implements a physical prototype for establishing a more organized and effective waste management system, promoting a sense of shared responsibility for a cleaner Ricanau Mofo.

This report illustrates the value of a multidisciplinary approach. By combining diverse expertise and conducting thorough analyses, the study provides a comprehensive understanding of Ricanau Mofo's environmental challenges. The proposed solutions for riverbank and soil erosion control, improved drainage, and effective waste management offer a sustainable path forward for the village's future development.
