Spatio-temporal simulation of a vineyard landscape
Abstract
Vineyard landscapes are issued from climate, agronomic and sociological factors. Since the post-war years, the wine-growing crisis, the changes in consumer’s habits and the mechanizing have deeply affected landscape architecture and composition of vineyards in South of France. Analysis of factors determining landscape evolution through the retro-observation help us simulating the future landscape for planning purposes. We analyzed the introduction of mechanizing in a 1 km² vineyard though the digitalization of aerial and satellite images from 1954 to 2012. Mechanizing is detected in theses images with the change in vineyard planting from staggered to lines rows of vines. Other land uses, as semi-natural habitats, forests, orchards, other cultures and urban zones are classified in the images. A probabilistic model based on a markovian process and calibrated using a random Forest algorithm is developed on the basis of the data constituted. The model simulate landscape evolution at the decade and at field resolution. The model calibrated on this example will be used to test introduction of new innovations to adapt the vineyard to climate change, such as the introduction of irrigation or the grape planting of vineyards drought-resistants.
