Impacts du changement climatique sur la phénologie du Pinot noir en Bourgogne
2013
The viticulture is an important economic and cultural sector in Burgundy. The current climate change raises a number of issues including its impact on crops. In this thesis, the idea is to develop a methodology to address the problem: what are the potential impacts of changes in temperature on the phenology of Pinot noir in Burgundy for years 2031-2048?The evolution of temperatures in Burgundy since 1961 is characterized by a positive temperature shift at the end of the 1980s followed by a period where the temperature increases of about 1.5 ° C.One of the interests of this thesis is to develop, following a strategy developed during the thesis, a spatial database conducted over the period 19…
Hydrologie, Changement Climatique, Adaptation, Ressource en Eau en Bourgogne : rapport final du projet HYCCARE Bourgogne
2016
HYCCARE Bourgogne est un projet de recherche-action dont l’objectif est de mettre à disposition des décideurs locaux des outils qui leur permettront de mieux prendre en compte le risque lié aux impacts du changement climatique sur la ressource en eau.

Carbon sequestration in French agricultural soils: A spatial economic evaluation
2021
International audience; Soil organic carbon sequestration measures entail costs to farmers with different individual characteristics and located in different areas. A cost‐effective analysis taking into account these heterogeneities is crucial for developing effective public policy aimed at increasing carbon sequestration. We undertake such an analysis focusing on three soil organic carbon sequestration measures: no‐till, extension of temporary grasslands, and hedgerows. Through an optimization model applied to France, our results show that only extension of temporary grasslands can store carbon at low cost, though their potential for carbon sequestration is also low. For an ambitious carbo…
Physiological advantages of dwarfing in surviving extinctions in high-CO2 oceans
2015
Excessive CO 2 in the present-day ocean-atmosphere system is causing ocean acidification, and is likely to cause a severe biodiversity decline in the future, mirroring effects in many past mass extinctions. Fossil records demonstrate that organisms surviving such events were often smaller than those before, a phenomenon called the Lilliput effect. Here, we show that two gastropod species adapted to acidified seawater at shallow-water CO 2 seeps were smaller than those found in normal pH conditions and had higher mass-specific energy consumption but significantly lower whole-animal metabolic energy demand. These physiological changes allowed the animals to maintain calcification and to parti…

Winter long dry spells in the Mediterranean basin and associated atmospheric conditions : contemporary and future variability (1957-2100)
2017
In the context of climate change, as reflected by a dryer Mediterraneanbasin, this thesis focused on the study of the contemporary and future variability(1957-2100) of the wintertime (September to April) very long dryspells events (called VLDSe) in the Mediterranean basin. An original methodologywas developed in this thesis in order to define VLDSe as singularclimatic events, characterized by location, duration and spatial extent criteria.76 VLDSe were detected in the Mediterranean basin on the contemporaryperiod (1957-2013). These events are divided into 4 main geographicalpatterns: North-East, West, Scattered Localized and South-East. North-East and West configurations are associated with…
PSDR 4 : Un programme d’aide a la structuration des filières protéines végétales en Bourgogne-Franche Comté
2016
BAPGEAPSIGESTADAGROSUPINRA; International audience; Afin de répondre aux enjeux actuels (réduction des intrants, circuits courts, changement climatique…) les acteurs chercheurs-professions-politiques de Bourgogne et Franche Comté, engagés sur la production de protéines végétales et leur utilisation en alimentation animale et humaine, ont convenu de construire une action PSDR 4 (Pour et Sur le Développement Régional ) visant le développement et la triple performance économique-environnementale- sociale de cette filière importante pour l'activité de ce territoire. L’ambition de ce programme est de répondre aux principales questions que se posent actuellement les différents acteurs de la filiè…
Méditerranée et mousson africaine : mécanismes et évolution dans l’actuel et le futur.
2014
6 pages; International audience; À partir d’observations in situ et analysées, de réanalyses atmosphériques, d’expériences numériques forcées parles températures de la Méditerranée, et de sorties CMIP5 issues de seize modèles couplés ayant participé au dernier exercicedu GIEC, nous tentons une synthèse des travaux collaboratifs entrepris au CRC ces cinq dernières années et portant sur lesinteractions tropiques/extra-tropiques au long du fuseau africain et sur leurs liens avec la mousson africaine. Après avoirrappelé le rôle des téléconnexions avec les grands bassins océaniques, de la circulation sur le secteur euro-atlantique et dela mousson indienne via le mécanisme de Rodwell-Hoskins, nou…
