Abstract

The objective of this paper is to characterize the relationship between the historical land uses developed on the island of La Graciosa (Canary Islands) and its aeolian sedimentary dynamics. The period between the second half of the eighteenth century, when historical sources confirm human presence on the island, and the present time, is analized. The methodology is based on the interpretation of different sources (historical documents, statistics, aerial photographs, oral testimonies) that allowed us to characterize the changes in the island during the period analyzed, both in terms of land use and aeolian geomorphology. The results suggest the existence of six stages, during which the intensity of human pressure on the environment changed. Therefore, the aeolian geomorphology has been altered, favoring the mobility or the stability of the aeolian sediments.
