Résumé : In the current context of agriculture, designing Multifunctional Vineyard Cropping Systems (MVCS) should aim to ensure agronomic performances while reducing environmental impacts, in a context of farming under socio-economical and technical constraints. We defined the MVCS as the association of a biophysical sub-system (BS) and a technical subsystem (TS) in dynamic interaction (Le Gal et al., 2010). BS is a combination of components in interaction, related to soil, grapevine, intercrop and pathogens (powdery mildew, mildew...), under the influence of the climate and technical operations which the components of TS (fig.1). TS is defined as the whole set of technical operations (from planting to annual harvest) acting, more often in interaction, on the biophysical processes. It is under the influence of farmers' decision system including pesticides application and their interactions with other technical operations. Therefore to design MVCS, it is necessary to take into account : - the interactions between TS components at field and farm scale in a context of limited resources (labour, equipement,...), - the interactions between BS components in each soil-climate elementary unit (intra-field), - the interactions between TS and BS. Our study aimed at developping a hierarchical analysis to elaborate a framework to model and design MVCS. In that paper, we present the results of a farm survey used to identify the hierarchical organisation of the MVCS. It is currently used to design organic MVCS taking into account the transition phase between the conventional system and the organic system.
