Training vineyards resilience to environmental variations by managing vine water use

Abstract

The challenges of the century for viticulture relate to coping with climate change and the loss of biodiversity in a downturning socio-economic context. Now more than ever, the vine and wine industry needs to be resilient to maintain and ensure a future for its heritage. An innovation of capital importance, in line with recently published research, deals with developing new methods of training our inherited and newly planted vineyards to better withstand environmental variations such as drought and heatwaves but also unevenly distributed rains and temperatures. In this work, vineyard resilience is defined as i) the ability to achieve a low inter-annual yield variability, while maintaining a level of quality defined by the production target, coupled with ii) efficient and minimized use of environmental resources such as irrigation water. The aim of this ongoing study is to determine the potential for improving vineyard resilience by following a training program based on innovative decision rules for vine water use management. The cultural practices involved are mainly canopy manipulation, cover crop management, fertilization and the timing and volume of irrigation when the vineyard is irrigated. To achieve this aim, 9 pairs of comparable blocks are hosting 2 management modalities: the first corresponds to the way the estate has always been run and the second corresponds to an innovative program to train the vineyard’s resilience. The studied blocks are situated in california (usa), chile, argentina, spain and france. Results for the first two years, 2023 and 2024, will be presented in terms of climatic conditions, yield level and variability, maximum sugar quantity per berry and amount of water supplied by irrigation where applicable.

Fomentar la resiliencia de los viñedos frente a las variaciones medioambientales con la gestión del uso del agua de la vid

Los desafíos del siglo para la viticultura están ligados al cambio climático y a la pérdida de biodiversidad en un contexto socioeconómico en declive. Ahora más que nunca, el sector de la vid y el vino necesita ser resiliente para mantener y garantizar un futuro a su patrimonio. Una innovación de capital importancia, en consonancia con los últimos conocimientos, consiste en desarrollar nuevos métodos de consolidación de nuestros viñedos antiguos y recién plantados para que resistan mejor las variaciones medioambientales, como la sequía y las olas de calor, pero también las lluvias y temperaturas desigualmente distribuidas. En este estudio, la resiliencia del viñedo se define como i) la capacidad de lograr una menor variabilidad interanual del rendimiento, manteniendo al mismo tiempo un nivel de calidad definido por el objetivo de producción, junto con ii) un uso eficiente y minimizado de los recursos medioambientales, como el agua de riego. El objetivo de este estudio en curso es determinar cómo se puede mejorar la resiliencia del viñedo a través de un programa basado en reglas de decisión novedosas para la gestión del uso del agua de la vid. Las prácticas culturales implicadas son principalmente la manipulación de la área foliar, la gestión de los cultivos de cobertura, la fertilización y el momento y volumen de riego en caso de que el viñedo sea regado. Para lograr este objetivo, 9 pares de parcelas comparables acogen 2 modalidades de gestión: la primera corresponde a la forma en la que siempre se ha gestionado el viñedo y la segunda corresponde a un programa innovador para fomentar la resiliencia del viñedo. Las parcelas estudiadas están situadas en california (ee.uu.), chile, argentina, españa y francia. Se presentarán los resultados de los dos primeros años, 2023 y 2024, en términos de condiciones climáticas, nivel y variabilidad del rendimiento, cantidad máxima de azúcar por baya y cantidad de agua suministrada por el riego, cuando hay riego.

Développer la résilience des vignobles aux variations environnementales par une meilleure gestion de la consommation hydrique de la vigne

Les défis du siècle pour la viticulture sont liés au changement climatique et à la perte de biodiversité dans un contexte socio-économique en pleine mutation. Aujourd’hui plus que jamais, l’industrie de la vigne et du vin doit être résiliente pour maintenir et assurer un avenir à son patrimoine. Une innovation d’une importance capitale, en accord avec les recherches récemment publiées, concerne le développement de nouvelles méthodes pour entraîner nos vignobles hérités et nouvellement plantés à mieux tolérer les variations environnementales telles que la sécheresse et les vagues de chaleur, mais aussi les pluies et les températures inégalement réparties. Dans ce travail, la résilience du vignoble est définie comme i) la capacité à atteindre une faible variabilité interannuelle du rendement, tout en maintenant un niveau de qualité défini par l’objectif de production, couplée à ii) une utilisation efficiente et minimisée des ressources environnementales telles que l’eau d’irrigation. L’objectif de l’étude en cours est de déterminer le potentiel d’amélioration de la résilience du vignoble en suivant un programme d’entraînement basé sur des règles de décision innovantes pour la gestion de l’utilisation de l’eau par la vigne. Les pratiques culturales concernées sont principalement les travaux en vert, la gestion de l’enherbement, la fertilisation et le timing et le volume des irrigations lorsque le vignoble est irrigué. Pour atteindre cet objectif, 9 paires de parcelles comparables sont soumises à deux modalités de conduite : la première correspond à la manière dont le domaine a toujours été conduit et la seconde correspond à un itinéraire technique innovant visant à améliorer la résilience du vignoble. Les parcelles étudiées sont situées en californie (usa), au chili, en argentine, en espagne et en france. Les résultats des deux premières années de l’étude, 2023 et 2024, seront présentés en termes de conditions climatiques, de niveau et de variabilité des rendements, de quantité maximale de sucre par baie et de quantité d’eau apportée pour l’irrigation, le cas échéant.

Shading nets for the adaptation to climate change: effect on vine physiology and grape quality 

Viticulture is threatened by the environmental modification caused by climate change. Higher temperatures determine an acceleration of the ripening process, which can be detrimental to wine quality. In the mediterranean area, heat waves are also increasingly frequent, with consequent blocking of the vegetative activity of the vines and increased susceptibility to sunburn damage. thus, adaptation strategies are necessary to reduce stress and improve the quality of grape production. Amongst the various techniques available, shading nets represent an interesting alternative for their effects on canopy microclimate (i.e., reduction of photosynthetic activity, improvement of water use efficiency, and slowing down in the ripening process).

Where the sky is no limit – the transformation of wine marketing through text-to-video generation AI models

The introduction of ai-driven tools in digital content creation represents a significant shift in the landscape of marketing, particularly for industries reliant on rich visual storytelling such as the wine sector. The development of ai models like openai’s sora, runway’s gen-2 or google’s lumiere, which can generate realistic video content from textual descriptions, offers promising new avenues for enhancing brand narrative and consumer engagement. This research explores the potential of text-to-video (t2v) ai models to revolutionize wine marketing by creating dynamic, engaging content that captures the essence of vineyards and their products without the need for traditional video production processes.

Ecodesign tools and approaches in viticulture for professionals and learners, contributions of the Vitarbae project

The agro-ecological transition in winegrowing can benefit from the environmental assessment of practices to inform producers’ technical choices. life cycle assessment (lca) evaluates the environmental impact of a product over its entire life cycle. this paper takes a look at the tools available for the detailed assessment and eco-design of winegrowing practices, their uses and developments in the vitarbae research project (2023-2026). this project aims to establish and equip support and training courses for the agroecological transition in viticulture and fruit arboriculture.

A survey on the rotundone content of 18 grape varieties sourced from a germplasm 

Rotundone, the pepper aroma compound, has been detected in wines made from a large number of grape varieties. However, given the fact that analyzed wines were sourced from different winegrowing regions and seasons, made using different winemaking techniques and at different scales, it remains difficult to assess the real variety potential to produce rotundone.

The French vine selection partners network: a unique device in the world at the service of safeguarding varietal heritage
