La construction historique des climats du vignoble de Bourgogne
2012
International audience; Il y a plusieurs façon de considérer les climats du point de vue historique et cela confère une vraie complexité à cette notion si représentative de la viticulture de terroir de nos jours. D'un point de vue formel, les climats sont en effet d'abord des parcelles cultivées en vignes sur les coteaux des côtes de Nuits et de Beaune, et leur construction peut être appréhendée comme celle de la constitution de ces parcelles. Or là, l'histoire remonte le plus souvent au Moyen Age, même si nous savons depuis peu que la viticulture existe au moins dès Ier siècle après J.-C. dans la plaine de Gevrey-Chambertin. Mais elle n'était alors pas pratiquée sur les coteaux et cette vi…

La vigne dans le paysage rural gallo-romain
2012
Catalogue de l'exposition : "Paysages en mouvement, les paysages du Mâconnais et du Val de Saône de la préhistoire à nos jours", Mâcon, de 23 juin au 28 octobre 2012; La culture de la vigne et la production de vin sont deux des traits marquants de la culture romaine. Avec la romanisation des villes et des campagnes gauloises, au début de notre ère, la viticulture est attestée par les textes et les découvertes archéologiques. Mais peut-on se faire une idée des changements que cette innovation a apportés dans le paysage agricole antique et en esquisser une image ?
On the relationship between some production parameters and a vegetation index in viticulture
2013
The use and timing of many agronomical practices such as the scheduling of irrigation and harvesting are dependent on accurate vineyard sampling of qualitative and productive parameters. Crop forecasting also depends on the representativeness of vineyard samples during the whole phenological period. This manuscript summarizes the last two years of precision viticulture in Sicily (Italy); agronomic campaigns were carried out in 2012 and 2013 within the "Tenute Rapitalà" and "Donnafugata" farms. Normalized Difference Vegetation Index derived from satellite images (RapidEye) acquired at berry set, pre-veraison and ripening phenological stages (occurred at June, July and August respectively) ha…
History of a Vineyard in Champagne: From Eighteenth to Twenty-First Century
2019
This contribution illustrates the history of the vineyard in Champagne in interaction with the invention of sparkling wines in an area of ancient viticulture. The socio-geographical configuration of this vineyard progressively changed, associating crises and expansions, at the end of which emerges in the twentieth century a vineyard very different from that existing in the early eighteenth century, when the sparkling wine was invented in the Champagne region. In the new Millennium, after the great crisis of the 2008–2009, the shipments of Champagne wines have remained stable overall for a decade, but only exports out of Europe have increased significantly. The sales of independent winemaker…

Biological protection against grape berry moths. A review
2018
International audience; Grape is a major crop, covering 7.5 M ha worldwide, that is currently being confronted with three main challenges: intensive pesticide use that must be reduced, invasion by new pests/diseases, and climate change. The biological control of pests and vectors would help address these challenges. Here, we review the scientific literature on the biological control of grape moths by macroorganisms (excluding nematodes). Two components, biological control with an active human role, mainly using biocontrol agents through inundation or inoculation, and conservation biological control, are considered. The major points are the following. (1) Tortricid grape moths seriously dama…
Estrazione e raffinazione dello zolfo e paesaggio nella Sicilia romana tra IV e VI d.C.
2016
Sulphur was important in several fields: military, tanning, wool’s disinfection and many other activities. Nevertheless, the largest quantity of sulphur was used in agriculture, particularly in viticulture as it was used to combat fungal diseases especially in wine production areas. Sicily, and in particular the area surrounding Agrigento, was the main site of sulphur extraction. This built strong relationships with Rome and other agricultural centres in the Mediterranean Sea. Very important among the historical sources and the archaeological evidence are the so called Tabulae sulphuris, concerning the sulphur exploitation at the Agrigento’s area. Recent finds and studies gave a new chronol…
