The Urban Exposome during Pregnancy and Its Socioeconomic Determinants

2018

Background: The urban exposome is the set of environmental factors that are experienced in the outdoor urban environment and that may influence child development. Objective: The authors’ goal was to describe the urban exposome among European pregnant women and understand its socioeconomic determinants. Methods: Using geographic information systems, remote sensing and spatio-temporal modeling we estimated exposure during pregnancy to 28 environmental indicators in almost 30,000 women from six population-based birth cohorts, in nine urban areas from across Europe. Exposures included meteorological factors, air pollutants, traffic noise, traffic indicators, natural space, the built environment…

Variabilité climatique printanière et phénologie végétale en Auxois : exemple d'Alise-Sainte-Reine (Côte d'Or).

2018

Un suivi photographique est effectué depuis 2011 sur le site viticole d'Alise-Sainte-Reine, dans l'Auxois en Bourgogne du Nord (département de la Côte-d'Or), afin de mettre en évidence des indicateurs permettant d'expliquer la variabilité interannuelle des stades phénologiques de certaines espèces végétales par l'analyse de la variabilité climatique et de la fréquence, succession et durée des types de circulation atmosphérique et de temps. Les photos prises au début du mois de mai montrent une différence sensible entre d'une part les années 2011 et 2018, et d'autre part les années 2016 et 2017. Sur la vigne de la parcelle sélectionnée et les arbres environnants, le déploiement des feuilles …

Analyse spatiale de l’évolution du risque de gel sur la vigne en Bourgogne-Franche-Comté

2019

The warming undergone by the global climate does not necessarily entail a decrease in frost risk in agriculture/viticulture. Since both plant and climate are likely to evolve under changing environmental conditions, plant vulnerability and the meteorological phenomenon (frost) should be considered jointly when assessing the evolution of frost risk. This study aims at documenting the spatial and temporal frost risk changes in the winegrowing subregions of Bourgogne-Franche-Comté. The period between budburst and the last spring frost occurrence date has been considered as the most vulnerable for grapevines. We considered a plant as being stressed by a frost event when the temperature drops be…

Developing fall-sown pea cultivars as an answer to the challenges of climatic changes

2012

Chapitre 4; International audience; Pea is considered rather well adapted to wide temperature ranges, with seedlings able to survive even -20 °C. From a physiological viewpoint, pea becomes tolerant to frost if first exposed to low non-freezing temperatures, causing the so-called cold acclimation. Delayed floral initiation helps some forage pea genotypes to escape the main winter freezing periods, as susceptibility to frost increases during the transition to the reproductive state. The oldest winter pea cultivars carry the dominant allele, Hr, although some bear hr. They are generally characterized by prominent winter hardiness and a long growing season, from sowing in early October until e…

Impact of climate change on water resource evolution in Burgundy, France (1980-2011) – Analysis of hydro-climatic parameters simulated at high resolution by a regional climate model (WRF) The regional climatic model ARW / WRF is used to make a dynamic downscaling of climate (driven by ERA-Interim) at a high spatial resolution (3 km2) over Burgundy, at daily time scale over the period 1980-2011. Climatic simulations were analyzed and compared with meteorological data, in order to validate them with the aim of their use by hydro(geo)logic models. The hydro-climatic parameters necessary as climatic inputs of these models, in particular precipitation and evapotranspiration, reproduce correctly …
