Le vignoble d’Azay-le-Rideau (XVIIe-XXIe siècles). À la recherche de facteurs de dynamiques spatiales

The long term-spatial dynamics of vineyards is influenced by a multitude of interacting factors. This study focuses on the Azay-le-Rideau vineyard from the 17th to the 21st centuries. We have data that allows us to examine five factors: topography, soil characteristics, demography, urbanization, and the impact of the AOC label. The first section analyses the profound spatial mutations that have taken place over four centuries. It reveals that the vineyards are relatively resistant despite cyclical periods of strong growth and equally sharp decay; they have also shifted to communal territories. The second section focuses on the impact of these five factors on the global dynamics of the vineyard. We demonstrate that they do not equally influence the development of vineyards and their influence varies from one era to another. We conclude with a summary of observations along with hypotheses on the weight of the different factors. As part of the regional program, VitiTerroir, the ultimate goal is to multiply studies and integrate different factors analysed in a multi-agent model to simulate the dynamics of the regional vineyards at different temporal and spatial scales
