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.

On sample preparation methods for fermentative beverage VOCs profiling by GCxGC-TOFMS

Study the influence of sample preparation methods on the volatile organic compounds (VOCs) profiling for fermentative beverages by GCxGC-TOFMS analysis. METHODS: Five common sample preparation methods were tested on pooled red wine, white wine, cider, and beer. Studied methods were DHS, Liquid-liquid extraction, mSBSE, SPE and SPME. VOCs were analyzed by GCxGC-TOFMS followed by data analysis with ChromaTOF. RESULTS: The volatile organic compounds (VOCs) profiling results were very dependent on the sample preparation methods.

Proposal of zonification and characterization of terroirs in the Yalde-Najerilla-Uruñuela vine growing area (DOC Rioja, Spain), based on the soil influence

Natural Terroir Units (NTU) are being delimited in vine growing area DOCa Rioja, in collaboration with Uruñuela Cooperative, to characterized specific and singular Tempranillo (Vitis vinifera

Evolution of acetaldehyde concentration during wine alcoholic fermentation: online monitoring for production balances

During alcoholic fermentation, acetaldehyde is the carbonyl compound quantitatively the most produced by yeasts after ethanol. The dynamics of acetaldehyde production can be divided into 3 phases. Early formation of this compound is observed during the lag phase at the beginning of fermentation before any detectable growth [1].

Three Nebbiolo clone anthocyanin profile as affected by environmental conditions

Vitis vinifera ‘Nebbiolo’ cultivar is a 3’-subsituted anthocyanin prevalent wine variety. It is grown in North-West Italy for the production of high quality ageing wines. In the present work berry skin anthocyanin amounts and profiles of the clones CVT 308, CVT 423 and CVT 142 were studied in 2004 and in 2005 in four environmentally different locations of North-West Italy: Donnas (steep mountain area), Monforte (hilly area, with a pH of 8.1), Vezza (hilly area, with a pH of 8.2) and Lessona (plain area, with a pH of 4.8).

Importance of matrix effects (wine composition) on protein stability tests of white and rosé wines

The presence of unstable proteins in wines can affect their stability and clarity. Before bottling, winemakers need to be sure that the wine is stable. A large number of stability tests have been proposed, usually based on heating a sample with a specific time-temperature couple. In practice, none is effective to accurately assess the risk of instability. Moreover, the interpretation of the results of these tests changes according to the region.
