Zoning, environment, and landscape: historic and perspective

Abstract

[English version below]

Dans une approche globale, nous proposons la définition suivante du zonage : “représentation cartographique associée à une sectorisation du territoire en zones unitaires homogènes à partir de facteurs discriminants établis sur la base d’indicateurs quantifiables et d’avis d’experts”. La première application de cette méthode a porté sur la caractérisation du terroir en liaison avec les aspects qualitatifs des vins. Il est également possible d’envisager d’appliquer cette démarche dans les stratégies environnementales et paysagères liées aux approches territoriales et aux pratiques viticoles. Cette méthode peut servir de base dans la mise en œuvre des outils financiers associés aux mesures environnementales (CTE, aides spécifiques). Le zonage est déjà utilisé sur le plan législatif vis-à-vis de l’utilisation des amendements azotés (zones vulnérables) et de la protection des espèces (biotope, natura 2000). Dans le cadre d’une application spécifique à la viticulture associé à la multifonctionnalité du terroir, plusieurs axes peuvent être envisagés:
– Vulnérabilité des sols au transfert de polluants,
– Cartes d’érosion et d’aptitudes à l’enherbement
– Caractérisation microbiologique des sols,
– Protection des paysages,
– Application sectorisée des modèles de prévision des maladies.

In a global approach, we propose the following definition as regards zoning: “cartographic representation associated to a division into sectors of the territory in homogeneous unitarian zones from discriminants factors established on the basis of quantifiable indicators and of experts opinions”. The first application of this method concerned the soil characterization in contact with the qualitative wine aspects. It is also possible to intend to apply this step in the environmental and landscaped strategies bound to the territorial approaches and to the wine practices. This method can serve as base in the application of the financial tools associated to the environmental measures (CTE, specific helps). Zoning is already used on the legislative plan towards the nitrogenous amendments use (vulnerable zones) and the sorts protection (biotope, NATURA 2000). Within the framework of a specific vine growing application associated to the soil multifunctionality, several axes can be envisaged:
– Ground vulnerabilities in the pollutant transfers,
– Cards of erosion and capacities in the enherbement,
– Microbiologie characterization of grounds,
– Landscape protections,
– Sectorised application of the disease forecast models.

THE EFFECT OF COPPER ON THE PRODUCTION OF VARIETAL THIOLS DURING THE ALCOHOLIC FERMENTATION OF COLOMBARD AND GROS MANSENG GRAPE JUICES

Nowadays, the rapid growth of vineyards with organic practices and the use of copper as the only fun-gicide against downy mildew raises again the question of the effect of copper on varietal thiols in wine, especially 3-sulfanylhexan-1-ol (3SH) and its acetate (3SHA). A few decades ago, several works indicated that the use of copper in the vineyard had a negative effect on the content of varietal thiols in Sauvignon blanc wines [1, 2]. However, these studies only considered the concentration of the reduced form (RSH) of varietal thiols, without quantifying the oxidised ones. For this purpose, we proposed to monitor both reduced and oxidised forms of varietal thiols in wine under copper stress during alcoholic fermentation to have a more complete picture of the biological and chemical mechanisms.

The soil biodiversity as a support to environmental sustainability in vineyard

The environmental biodiversity is important to guarantee essential services to the living communities, its richness is a symptom of a minor disturbance and improves he environment biological quality.

The “green gold” @fem: assessing grapevine germplasm diversity to crossbreed the varieties of the future

Context and purpose of the study. To date over 3,000 grapevine accessions have been collected at Fondazione Edmund Mach (FEM).

Pesticide – Free viticulture: towards agroecological wine-producing socio-ecosystems

Can we cultivate grapevine without pesticides? This is a huge challenge for this emblematic crop, which is one of the largest users of plant protection products. Pesticides are mainly used to protect the vine against leaf diseases (powdery mildew, mildew, black-rot), even in organic farming, which uses copper in particular. What are the research avenues that can help eliminate pesticides today?

Étude des potentialités des terroirs viticoles: une démarche globale en zone A.O.C. L’exemple des Côtes du Rhône

Depuis près d’une quinzaine d’années, l’Appellation d’Origine Contrôlée (A.O.C.) Côtes du Rhône a engagé un vaste programme afin de mieux connaître et valoriser les potentialités des différents terroirs qui la composent.
