“…Les résultats par kg et par ha ont conduità un classement différent, en raison des variations de rendement entre les sites et entre les années, ce qui augmente la variabilité de l'impact lorsqu'il est comptabilisé par kg de raisin [24] et cette variabilité est constatée en général dans l'agriculture [25]. Par rapportà l'agriculture conventionnelle, les rendements en agriculture biologique sont inférieurs de 20à 25 % en moyenne [26,27].…”

Contexte : La viticulture est très exigeante en intrants. La viticulture biologique est souvent considérée comme un système durable, mais elle a des impacts environnementaux. L'analyse du cycle de vie (ACV) permet de discriminer les itinéraires viticoles. Objectif : Notre article présente et discute l'intérêt de l'ACV pour évaluer, comparer et améliorer les itinéraires viticoles biologiques par une comparaison (i) des inventaires des pratiques, (ii) des inventaires du cycle de vie (ICV) et (iii) des ACV. Matériel et méthodes : Huit cas ont été étudiés dans trois régions viticoles françaises et deux années. L'ICV et l'ACV ont été calculés, cinq impacts ont été sélectionnés par corrélations (changement climatique, eutrophisation de l'eau douce, écotoxicité terrestre, acidification terrestre, eutrophisation marine). Résultats et discussion : des différences importantes entre les cas pour les pratiques et les quantités d'intrants ont été observées et l'étude des impacts sur le changement climatique a révélé la hiérarchie d'importance des opérations notamment mécaniques et un classement différent pour des impacts au kg de raisin et à l'ha de vigne. Les défis de l'ACV sont de mieux prendre en compte le soufre et le cuivre ; enrichir les bases de données sur les engrais organiques ; et construire des indicateurs de biodiversité. Conclusion : L'ACV est meilleure que les inventaires des pratiques pour évaluer la viticulture biologique. Mots-clés : évaluation environnementale, viticulture durable, conduite de la vigne, cuivre, carburant, fertilisation.

“…The average annual climatic features, based on 1981-2010 data from Météo-France, the French national meteorological service, gathered at the "Carpentras-Serres" site, are the following: (i) minimum temperature, 8.1 • C; (ii) maximum temperature, 20.6 • C; (iii) rainfall, 648 mm; and (iv) number of rainy days, 65.7 days. Following the methodology proposed by Renaud-Gentie et al [35], we performed a hierarchical classification on these climate data. We used the monthly rainfall amounts and monthly average minimum and maximum temperatures from April to September for the years 1993 to 2017.…”

Effect of Conversion to Organic Farming on Pest and Disease Control in French Vineyards

Since 2006, an increasing number of French vineyards have chosen to convert to organic farming. One major change in vineyard practices includes replacing chemical pesticides with copper and sulfur-based products in line with Council Regulation (EC) No. 834/2007. This change can make overall management and pest and disease control more difficult and potentially lead to yield losses. From 2013 to 2016, a network of 48 vineyard plots, in southern France, under conventional management and in conversion to organic farming were monitored throughout the three-year conversion phase to investigate the grapevine phytosanitary management of four major pests and diseases and variations in control efficiency. The severity of downy and powdery mildew, grape berry moths, and Botrytis bunch rot were assessed and linked to the protection strategy. The findings showed that pests and diseases were controlled in the third year of conversion at similar efficiency levels as in conventional farming. However, the first two years of conversion were a transitional and less successful period during which higher incidences of cryptogamic diseases were observed. This demonstrates a need for winegrowers to receive more in-depth technical advice and support, especially on pest and disease control, during this critical transition period.

“…However, for various crops, a lower yield has been observed for organic farming as compared with conventional farming (Seufert et al 2012). This is also the case for vineyard systems, which were studied by Renaud-Gentié et al (2019). However, despite reduction in synthetic chemicals, organic viticulture in certain situations still uses higher amounts of sulfur, copper, and diesel for synthetic herbicides and fungicides.…”

“…Moreover, organic viticulture may be more sensitive to interannual variations of intervention frequency than conventional viticulture. The study of Renaud-Gentié et al (2019) identified the main pathways for environmental improvements in organic viticulture by increasing energy efficiency of the farm machinery, reducing the impacts of harmful chemicals by appropriate choice of substitutes and dose management.…”
