A method to identify and map the land use patterns relevant for environmental services in agricultural landscapes

Une méthode pour identifier et spatialiser les mosaïques d'usages du sol en lien avec les services environnementaux des paysages agricoles

Résumé

The association of natural and farmed areas is of primary importance for ecological networks in agricultural landscapes. The main goal of this work is to present a method to rapidly quantify and map the spatial configurations (SC) of the main landscape elements in farmed landscapes. Such land use patterns are relevant for agro-environmental policies since a better knowledge of main CS in landscapes is needed. The method we developed was in four steps: (1) to identify the main objectives of agro-environmental policies and of their relationship with local land uses; (2) to qualify the CS relevant for policies through field surveys, aerial photos observation, qualitative spatial representations, also in order to describe each CS by spatial indicators; (3) to test the relevance of the indicators describing CS using Pearson Chi-squared and Wilcoxon signed rank tests; (4) to map the spatial distribution of the identified CS in the analyzed agricultural landscape. We applied this method to a case study in Southern Tuscany, a Mediterranean inland hilly landscape of 1500 ha. Five CS were identified and described. Selected indicators were proper to distinguish CS. The mapping of the CS showed a total coverage of the analyzed landscape, with some overlapping among different CS. The method reliability has been tested on another grassland oriented landscape in Central France showing a higher predictive value of agro-environmental services for Mediterranean landscapes characterized by an higher land use diversity.
