MODE RESPYR project founded by the French Research Agency (ANR) is presented. Combining multi-temporal data as well as combining multi-scaled data is original to provide knowledge on past landscape changes in the Pyrenees. Multi-temporal data regroups palaeo-environmental data and land cover maps made from historical aerial photographs (from 1940’s to 2000’s). Multi-scale data are based on regional satellite images (from the 1990’s) and aerial photographs on three local study sites. First results obtained provide a fine quantitative and spatial characterization of landscape’s dynamics, i.e. the relations be tween land uses and land covers changes which areessential for modelling future changes based on combined scenarios and models. Finally this poster illustrates the interest of a multidisciplinary approach to improve the modelling of past and future land cover changes.
