“…-The results obtained for the subunit agricultural and production areas corroborate with the conclusions drawn by Panagopoulos [10], according to which the organization of agricultural production landscapes tends to be associated with a low aesthetic quality; -Although marshes are considered as one of the richest ecosystems in environmental and ecological perspectives, it appears that, regarding landscape visual quality, this ecosystem/landscape subunit is characterized by low values, when compared to other landscape subunits considered in the present study; -Though the subunit Touristic Complex and Golf obtained the highest result considering respondents' preferences, the fact that the "Presence of Water" parameter was considered as the most relevant to landscape quality might have influenced the results; -While about half of the respondents agree that the construction developments along the riverbanks contribute to the degradation of landscape quality, it appears that the touristic complex and golf subunit, which corresponds to the various buildings associated with tourism developments, was the one that obtained a higher preference; -Although it is considered important that each visitor spent on average about 50 Euros to visit this landscape, it should be noted that this value may be overinflated considering the assumptions made by Seling and Spathelf [20], according to which the money spent in certain trips cannot be exclusively attributed to a specific component of the trip. Furthermore, the importance of this landscape at regional, national and international levels is supported by the analysis of the residence areas of each of the respondents/boat users, since approximately 70% had to travel more than 50 kilometers to visit this landscape.…”
