Abstract
Gully erosion in the Penedès-Anoia (NE Spain) region is not a past phenomenon. In this respect, recent research by Martínez-Casasnovas et al. (2003) has shown that neat erosion rates in gullies reach 576±58 Tn ha-1 year-1 in the most active heads. However, some research questions arise about the magnitude of this problem: When did gully erosion start? When did it was accelerated? Is this acceleration related to the main land use in the region (vineyards)? The present work addresses those questions by analysing multitemporal remote sensing data in order to determine historic gully retreat rates and to relate them to documented land use changes in the region.
