Human impact on the scenic quality of coastal dunes: A study of the central Caribbean coast of Colombia

This paper provides a scenic assessment of 19 dune sites using the Dune Scenery Evaluation System (DSES). The DSES assesses values from a checklist of 18 physical and 8 human parameters and allows the calculation of a scenic evaluation index (D Value), which classifies D sites into five classes: Class I, usually natural areas of top scenic characteristics, to Class V, poor scenic dune areas with a greater impact of human interventions. Our findings reveal a predominance of coastal dune systems falling into middle to lower scenic quality classes (III, IV, and V), indicating considerable degradation due to intense human activities. Notably, these activities have adversely impacted the structural integrity and scenic value of these dunes, leading to a loss of biodiversity and increased vulnerability to natural hazards. This paper highlights the critical need for integrated coastal management strategies that balance conservation with sustainable development. Furthermore, our study proposes the enhancement of existing regulatory frameworks, community engagement in conservation efforts, and the implementation of ecological restoration projects aimed at reversing the degradation and restoring the ecological and scenic value of these vital landscapes. The findings underline the potential of using scenic quality as an ecological indicator to guide conservation and management practices, ensuring the preservation of coastal dunes, which are essential for ecological sustainability and local economic benefits. This multidisciplinary approach not only enriches our understanding of the complex interactions within dune ecosystems but also sets a precedent for future research and policymaking in coastal zone management.
