Urban sprawl, causing increasing disappearance of arable land, is generating a great pressure on agricultural land (Lefebvre and Rouquette, 2011). This impacts particularly small farms in peasant agriculture that are no longer able to compete with large intensive farms (Agreste, 2021), which weakens the food autonomy and diversity of territories (Plénet et al., 2018) and is reconfiguring agricultural land. Many actors are thus trying to support extensive agriculture by offering it perennial or transitory access to agricultural land. Our project experiments with a semi-automatic search model for the availability of agricultural land and wasteland with GIS. It aims to test and prove a method proposed by CERESCO (CERESCO, 2020) and to make it evolve in order to propose a tool mobilizing generic spatial data, deployable on the whole French territory. Initially, a study of territorial zoning highlights areas threatened by urbanization and the potential for development of farms. The cross-referencing of heterogeneous spatial data makes it possible to identify land with agricultural development potential. The precision of the cadastral division offers a localized communication support adapted to the needs of the territory's actors and farmers in search of land. Aware of these issues, the agglomeration of Compiègne (ARC) and the association Terre de Liens wish to encourage the establishment of small farms on their territory. The Hauts-de-France region, marked by a strong intensive agricultural tradition, is nonetheless fragile: Compiègne is ranked 97th out of 100 French cities in terms of food resilience, with an autonomy of 0.16% (Utopies, 2017). This methodology was applied to the 78 municipalities of the Grand Compiégnois area to test its heuristic capacities for food resilience. This search for unused parcels, allowing for the possibility of transitional agriculture, offers a new temporality to agriculture and participates in increasing the food autonomy of territories.
