Application of DEXI PM Vigne sustainability tool to the assessment of alternative vineyard protection strategies
Implementing alternative grapevine systems that incorporate sustainable strategies and innovative farming practices is essential. However, we lack tools for measuring the impact of these new practices on the overall sustainability of vineyards. DEXi PM Vigne (Gary et al., 2015) is a tool developed for ex ante assessment of the sustainability of grapevine cropping systems, from the plot to the farm scale. In the present study, we focused on implementing new strategies of integrated crop protection management with limited pesticide use in vineyards. These strategies were developed by several local agents and experts using the CAPiPP serious game (Hossard et al., 2022) in different types of vineyards in the Rieutord basin, located in Languedoc, France. We applied DEXi PM Vigne to three types of vineyards: conventional and PGI wine labels, organic and DOP wine labels, and organic and mixed wine labels. The strategies chosen during the game workshops were used for the assessment. The results of the assessment revealed improvements in environmental indicators, moderate improvements in social indicators, and slight declines in economic indicators due to the risk of yield losses, particularly during years with high disease pressure. The application of the DEXi PM Vigne tool proved to be helpful in conducting an ex-ante assessment, which can assist winegrowers in considering future impacts before implementing new management strategies.
