Abstract

The evolution of the erosion rates in the Guiniguada ravine (Gran Canaria, Spain), between 1960 and 2012, is here analyzed. For the study, the empirical model USLE is applied, adapting it to the specificities of the Gran Canaria, and the analysis are developed using GIS. The results show that the anti-erosion efficiency and landscape quality of terraced surfaces in the study area have been unevenly affected by the increase of erosion rates.
