Il ruolo dei comuni nella gestione del territorio e nella tutela dei vitigni autoctoni di qualita’

Context and purpose of the study. Climate change is already threatening California vineyards, as they grapple with increasing extreme weather events and drier growing seasons.

In this video recording of the IVES science meeting 2023, Stéphanie Marchand (University of Bordeaux, ISVV, INRAE, UMR 1366 OENOLOGIE, Villenave d’Ornon, France) speaks about the aromatic maturity as a cornerstone of terroir expression in red wine. This presentation is based on an original article accessible for free on OENO One.

The mapping of spatial variability in vineyards offers the potential to implement zonal management strategies with the aim to optimize economic benefits and increase sustainability by managing natural resources, such as water used for irrigation, more optimally. This study characterized the (natural) variability in plant water status in a commercial Cabernet Sauvignon block, using remote sensing techniques, and identified the impact of this variability on the yield, and juice and wine composition. From the field data collected over two growing seasons, we demonstrated that remote sensing techniques are a practical and powerful tool for mapping spatial variability within vineyard blocks.

The French vine selection partners network is currently made up of 40 regional partners, grouped around IFV (French Institute for Vine and Wine) and INRAE (national research institute for agriculture and environment), whose missions are preservation, selection, and innovation of our varietal diversity. The originality of this device is based on a 3-level organisation: – varietal diversity preservation, with the world reference: the INRAE’s vine genetics resources centre of Vassal-Montpellier (Marseillan, France), the world’s largest ampelographic collection, which includes nearly 6 000 accessions of cultivated Vitis vinifera from 54 countries, as well as rootstocks, interspecific hybrids, wild vines (lambrusques) and wild American and Asian species.

Nowadays biodiversity loss is considered as a prior environmental issue. Agricultural landscapes are particularly concerned, mainly through the specialization and intensification of farming activities which lead, at a larger scale, to landscape simplification. Landscape management would be a good means to halt biodiversity loss, but large-scale studies remain rare. The life+ project BioDiVine aims to understand biodiversity dynamics and promote sustainable conservation actions at this scale in viticulture.
