This paper analyses how terroir-driven wine producers in Portugal’s Douro Valley address current and emerging sustainability challenges while preserving cultural authenticity and the unique identity of their wines.
Even if there are historic evidence of the cultivation of the vine in Normandy (France) before the XXth, the winegrowing area had completely disappeared.
The French Appellation of Origin system (AOC/AOP) is based on the delimitation of zones in which grapes and subsequent wines meet production criteria (pedo-climatic conditions of production, varieties, growing and wine-making practices) expressing the links with the terroir of origin.
Sustainability is a challenge faced across all sectors of society, considering resource use, impact mitigation, and increasing pressures from climate change.
Context and objective: The increase in drought across most of the world’s current wine-growing regions due to climate change is raising the issue of sustainable water management.
Agroforestry in vineyards has been proposed as a strategy to buffer climatic stress, potentially moderating microclimate and enhancing water availability for the vines.
Grapevine (Vitis vinifera) is the world’s third most valuable horticultural crop. Today, climate change significantly threatens grape productivity, notably due to more frequent and extended drought periods.
In viticulture, the evaluation of scion varieties and rootstocks relies on multi-site field trials that must be maintained and monitored for several years once the vineyards become productive.
Climate change is driving the wine industry to re-evaluate the appropriate use of rootstocks. The French network of vine rootstock experiments, established by research and technical institutes,
Stable isotopes of carbon (δ¹³C) and nitrogen (δ¹⁵N) provide valuable integrative indicators of grapevine water status (Gaudillère et al., 2002; van Leeuwen et al., 2023) and nitrogen metabolism (Santesteban et al., 2015, (Santesteban et al., 2024).
