“…The use of satellite images from Google Earth and drone orthomosaic photos, in conjunction with Geographic Information System (GIS), has progressively improved resolution and versatility for shoreline extraction and mapping of changes in migration [84,86,[101][102][103][104][105]. In this study, the changes in the shoreline were analyzed over 16 years (2004-2020).…”

Large Woody Debris (LWD) accumulation serves essential ecological functions and benefits society’s coastal ecosystems (e.g., beaches). Thus far, the ecosystem services perspective has paid little attention to LWD. Therefore, we aim to contrast social perceptions on LWD and its ecological significance in Puerto Velero beach, Caribbean, Colombia. In consequence, the contribution of LWD to the conformation and creation of Puerto Velero beach was analyzed, as well as how beachgoers perceive the importance of LWD and if they were willing to pay to remove LWD in this beach. To achieve this, a quantitative convergent approach was then proposed using GIS analysis and remote sensing to understand the contributions of LWD to the Puerto Velero beach ecosystem; and in addition, a survey was performed to determine how beachgoers perceived LWD and how they valued the phenomenon. Results indicate that LWD contributed to beach maintenance; nevertheless, most people neglected LWD values because of its lack of visual attractiveness. As such, ecosystem services targets become conflicted because people positively perceived ecosystem services provided by beaches, but they did not assign importance to the beach dynamics they deemed unattractive, regardless of their vast importance.

The Isla Salamanca coastal barrier on the Colombian Caribbean coast faces significant erosion, driven by climate change-induced, sea level rise and human activities such as highway construction. The Barranquilla-Ciénaga highway, particularly at kilometers 19 and 29, is at risk, with severe consequences for the region’s socio-economic and environmental well-being. Human interventions like the highway construction and seawall installations have disrupted the natural coastal dynamics, leading to increased erosion rates. The study, conducted between 2004 and 2021, reveals that the Isla Salamanca coastal barrier is experiencing substantial transgression, with erosion rates peaking at -16.1 m·yr− 1. The highway protection measures, with seawall construction, have proven inadequate, exacerbating erosion downstream. The mangrove loss due to hydrological changes and increased salinity is further threatening the fragile ecosystem. The research emphasizes the importance of considering biodiversity loss in the context of rapid erosion rates. The region, declared a Ramsar Site and Biosphere Reserve, hosts vital ecosystems like mangroves and dunes, whose destruction negatively impacts marine biodiversity. The study suggests the relocation of the highway, acknowledging the challenges of preserving wetlands and mangroves in the process. Balancing the need for infrastructure with ecological preservation is essential, and the study proposes comprehensive solutions, including shoreline management, ecosystem-based protection, and community involvement. The goal is to mitigate erosion’s adverse effects on biodiversity, habitat integrity, and the overall health of this ecologically sensitive region.
