Assessing the scenic quality of transgressive dune systems on volcanic islands. The case of Corralejo (Fuerteventura island, Spain).

The formation of transgressive aeolian sedimentary systems on hot-spot volcanic islands results in globally singular conditions. The natural attractions and landscape features of these spaces can result in the concentration of urban-tourist developments in their surroundings, altering their physical integrity and their ecological and scenic functionality. This has been the case of the Corralejo dunefield in Fuerteventura (Canary Islands, Spain), where the strong pressure exerted by tourism is endangering the area's natural and landscape resources. This study aims to qualitatively assess the landscape heritage through a number of indicators, some of which are developed on the basis of user perception. Four landscape dimensions (substratum, sea, vegetation, and scenic background) were used to analyse the 24 landscape units into which the Corralejo beach-dune system was divided. The results show that this system presents a high landscape value, as do its four different dimensions. This value was found to decrease in areas bordering the urban area or where tourists were commonly present. Recommendations are proposed to improve the area based on user perceptions. This type of research is of interest for future planning, ordinance preparation and management with a view to establishing a balance between the physical medium and anthropic pressure.
