Declining vineyards are assessed by a multi-year decrease in vine productivity and/or its sudden premature or gradual death, based on multiple factors. Since 2015, the French wine sector has been working on an original study to identify new research avenues while launching an innovative action plan to combat vineyard decline. First, a statistical analysis enabled to estimate research efforts in the different countries. 70 factors susceptible to contribute to vineyard decline were then identified by analyzing more than 500 publications. These factors are biological, physical or linked to growing practices. While the role of pathogens is fairly well-known, the impact of the land plot or the soil on decline is less understood. Secondly, a prospective methodology was used to better identify viticulture system factors and levers affecting vines. It was thus demonstrated that yield and longevity are strongly linked to agronomy, economic variables and plant matter, plant physiology, disease, etc... These are the key issues and leverage actions to combat more strongly vineyard decline. The matrix analysis was then complemented by interviews and statistical data to imagine leverage actions. The strategic action plan is focused on four objectives: promoting training of good practices, improving plant production organization, developing vineyard observation networks, implementing an innovative research plan.
