Résumé
This work is based on the hypothesis that a participatory approach and serious game that places landscape at the centre of its focus can extend beyond individual actions in encouraging more effective concerted action to limit the contamination of watercourses due to plant protection products. An interdisciplinary approach (involving the fields of socio-anthropology, concertation sciences and earth sciences), based on co-construction workshops held with local stakeholders, has led to the creation of the CAUSERIE game. This so-called 'hybrid' game relies on a GIS model of the catchment area, namely GEOMELBA-SPIRIT, that explicitly represents the influence of the spatial distribution of typical cropping systems and landscape infrastructure (grassy strips, hedges, ditches, constructed wetlands), in order to examine the role of collective action and its associated levers. This approach has been parameterised for both viticulture and mixed farming activities.
