Localització dels conreus irrigats de la plana de l’Alt i el Baix Empordà a través de l’anàlisi geohistòrica i de la teledetecció

The Empordà region (northeastern of Catalonia) displays one of the most diversified and rich agrarian landscapes of Catalonia. The article is an example of joint use in affluent the agricultural analysis of two differentiated disciplines until the present time: geo-history and remote sensing. On the one hand, geo-history has allowed analyzing the human transformations and their repercussions in the most significant crops of the plains of the Alt and the Baix Empordà from century XVIII. Because of the similar geophysical structure and geo-historical evolution, for example with dryings of lagoons or the deflections of the final sections of the fluvial courses, the two plains have been dealt jointly. Of the other hand, remote sensing through satellite images has allowed mapping the crops of year 2004 with a high reliability thanks to the used method and the geo-historical analysis.
