Zonage viticole des surfaces potentielles dans la vallée Centrale de Tarija (Bolivie)

Abstract

[English version below]

La présente étude de zonage viticole a été faite dans la région de la vallée Central de Tarija(VCT), dans la ville de Tarija, au Sud de la Bolivie; une région avec plus de 400 années de tradition qui présente une vitiviniculture de haute qualité. La Vallée possède une surface total de 332 milles ha.; existant des vignobles entre 1660 y 2300 m.s.n.m. et dans ce rang d’altitude il existe 91 mille ha. avec un haut potentiel pour la culture de la vigne. Pour la détermination des surfaces homogènes de la région ont été considérés les aspects d’environnement avec l’aide d’images satellitaires, des cartes topographiques, des données climatologiques et des cartes géologiques ; pour déterminer les caractéristiques de la région pour la culture de la vigne. Au niveau climatique furent appliqués les indices du Système CCM Géo viticole développés par Tonietto & Carbonneau (2004), lesquelles considèrent des éléments thermiques (Indice Héliothermique), hydriques (Indice de sécheresse) et nictothermiques (Indice de Froid nocturne); nous avons identifié 8 types des climats différents dans toute la région. Dans les particularités du sol furent déterminés la morphologie et il a été géo référencié tous ses caractéristiques (analyses chimique et physique). S’ai fait une classification spécifique des critères de culture de la vigne pour déterminer l’aptitude du sol, en même temps ont été identifié les surfaces avec des limitants pour le conduit des vignobles. L’étude a pour objectif d’identifié les zones potentielles pour la culture de la vigne et de cette façon orienté son élargissement avec le support des politiques d’état et pertinente assistance technique au producteurs de cette région.

This study of vitivinicultural zonation was carried out in the region of the Central Valley of Tarija (VCT), in the Department of Tarija, southern Bolivia, a region with more than 400 years wine tradition which actually presents a high quality. The valley has an area of total 332 thousand ha.; vineyards exist between 1660 and 2300 m.a.s.l. and in this altitude range there are 91 thousand hectares with a high potential for growing grapes. In the determination of homogeneous areas of the region, we considered the environmental aspects through satellite images, topographic maps, weather data and geology maps; thus the characteristics of the region for growing grapes were defined. Considering climate, we applied the Geoviticulture Multicriteria Climatic Classification System developed by Tonietto and Carbonneau (2004) which considers a heliothermal index (HI), dryness index (DI)) and a cold night index (CI), in this way there were 8 different types of climates identified throughout the region. For the characteristics of soil we determinated its morphology and did chemical and physical analysis, all dates were georeferenced. We realized a classification including the specific requirements and limits of grape plants to determine the aptitude of the soil. This study aims to identify areas with high potential for growing grapes and thus directing the growth of the sector, with support of state policies and suitable technical assistance to growers in the valley.

Downscaling of remote sensing time series: thermal zone classification approach in Gironde region

In viticulture, the challenges of local climate modelling are multiple: taking into account the local environment, fine temporal and spatial scales, reliable time series of climate data, ease of implementation and reproducibility of the method. At the local scale, recent studies have demonstrated the contribution of spatialization methods for ground-based climate observation data considering topographic factors such as altitude, slope, aspect, and geographic coordinates (Le Roux et al, 2017; De Rességuier et al, 2020). However, these studies have shown questions in terms of the reproducibility and sustainability of this type of climate study. In this context, we evaluated the potential of MODIS thermal satellite images validated with ground-based climate data (Morin et al, 2020). Previous studies have been encouraging, but questions remain to be explored at the regional scale, particularly in the dynamics of the massive use of bioclimatic indices to classify the climate of wine regions. The results at the local scale were encouraging, but this approach was tested in the current study at the regional scale. Several objectives were set: 1) to evaluate the downscaling method for land surface temperature time series, 2) to identify regional thermal structure variations. We used weekly minimum and maximum surface temperature time series acquired by MODIS satellites at a spatial resolution of 1000 m and downscaled at 500 m using topographical variables. Two types of analyses were performed:

Multiple description and validation of autochthone grape varieties in the Carpathian Basin

Context and Purpose of the Study. In many countries, the preservation of grape varieties with heritage value is ensured by genebanks of outstanding significance, which allow for the study of these varieties and the assessment of their future roles in response to environmental, market, and social challenges.
