Changement climatique : impacts sur la phénologie du Pinot Noir en Bourgogne.
2010
6 pages; International audience; Cette étude traite de l’impact du changement climatique sur les potentialités climatiques viticoles du Pinot Noir enBourgogne. L’analyse stationnelle révèle que le réchauffement récent observé en Bourgogne induit une précocité des stadesphénologiques de 10 à 25 jours. Un modèle phénologique est utilisé pour modéliser la relation entre la température et lavigne et affiche une plus grande performance (R²>0.9) sur la prédiction de la date de floraison et des résultats pluscontrastés pour les dates de véraison et de maturité (respectivement R²~0.78 et R²~0.80). Il est ensuite appliqué auxtempératures simulées par le modèle ARW/WRF à 8km de résolution, dans le bu…

7 pages; International audience; Sahelian regions are considered as particularly vulnerable to climatic variability and change for two reasons: the dominant role of rainfed agriculture in their economies and their weakness of water resources management. The physiological response of an individual plant to the climatic variations of parameters is well documented, but extrapolation to regional food production still remains very dubious. On the Bani, a tributary of the Niger River in Mali, climatic variables representative of the agroclimatic constraints of the cultures (dynamics of the rainy season and occurrence of extreme events) were evaluated from observed past data and simulated future d…

How abrupt change in surface temperature impacts water balance over France? A case-study of bread wheat cultivated areas.
2022
Agricultural risk management is a major challenge for decision makers, public authorities and agricultural insurance companies, as crop losses linked to climate hazard are expected to increase in the context of climate change (Boucher et al., 2019). The present work is part of a PhD in partnership between Groupama insurance company (Domaine Assurance Récolte) and Biogeosciences laboratory (University of Burgundy). This collaborative research aims at depicting how, with the abrupt surface temperature warming, climate hazard evolution has affected water balance over France, and related agro-climatic risks.Since 1980s over western Europe, the warming trend intensifies strongly, consistent with…
