GiESCO 2013 – Session 4: Environment–climate and soil

Climate change is now underway and is becoming increasingly an additional constraint, requiring adaptation in viticulture, as in oenology.

The increasing temperatures, caused by the global change, lead to an earlier onset of developmental stages, changes in productivity and physiology of different crops and will challenge the growers in the future.

Healthiness is a prerequisite for all agricultural products, foods and beverages. The presence of arsenic (As) in these products creates concern, due to its carcinogenicity.

Three different plot soils in a vineyard were characterized. The soils belonged to the Luvisol and Cambisol groups. In each case, major and trace element contents were determined in topsoil, leaf and grape samples.

Optimal climatic demands of different winegrape varieties are specific to each viticultural region. In this context, an innovative category analysis is used as a zoning tool, depicting the suitability of a particular region for winemaking.

Using spectrophotometric and chromatographic methods were evaluated the influence of climatic conditions and rootstock on the phenolic composition of young varietal wines on tropical wines-area, produced from cvs. Cabernet Sauvignon, Marselan, Syrah and Tempranillo, during 2009-2010

The ‘Circuito das Frutas’ is an important region for fruit production in the State of São Paulo, Brazil. It is a region with great attractions associating tourism and wine production.

The rising importance given from legislators and consumers to provenance of food purchased and/or eaten, in last years motivated several researches to identification of the geographical origin of food.

Data from a selected geographic areas in the Silesian region of south-western Poland is used to evaluate vineyard and wine grape growing suitability using a knowledge-based suitability model (TSVS) developed by Terra Spase and tested in vineyards in northern California.

Wine production is known to be largely dependent on favorable environmental conditions. The Douro Valley in Portugal is known for its world-famous wines, such as Port Wine.

Green manures are plants grown to improve soil fertility. This technique which is implemented in many cropping systems such as field crops or vegetables is still few studied in viticulture.

We tested the hypotheses that heat waves occurring before budbreak advance budbreak date and increase shoot growth rate due to greater density and size of xylem vessels in irrigated Malbec vines (Vitis vinifera L.) in Mendoza, Argentina.

Grapes are one of the most important fruit crops in the world, especially for winemaking.

Information on soils is becoming more and more important for viticulture since several factors that influence grape and wine quality are related to soil properties.

The paper presents the issues and the first syntheses of LACCAVE project that links INRA researchers working on the adaptation of the wine sector to climate change.
