This article describes extreme indices maps (Data Cube, raster X Time) for different scenarios with a more important contribution to the sea level rise from Greenland and/or Antarctica during the 21st century under the Representative Concentration Pathway (RCP) 8.5 emission scenario. The indices are produced annually and globally with a resolution ...
The need to reconnect agriculture, environment, food, and health when addressing agrifood system transitions is widely acknowledged. However, most analytical frameworks, especially in the expanding literature about “system approaches”, rely on impact-based approaches and, thus, tend to overlook ecological processes as well as social ones. This arti...
Les sciences agronomiques ont incorporé ces dernières années un ensemble de mots clés et de concepts qui, parfois mal relayés ou utilisés hors contexte, peuvent être une source de malentendus sur l'origine et l'impact des actuels dérèglements environnementaux. L'objectif de ce rapport est de clarifier le cadre d'utilisation de cinq termes courammen...
Temperate plants are at risk of being exposed to late spring freezes. These freeze events—often called false springs—are one of the strongest factors determining temperate plants species range limits and can impose high ecological and economic damage. As climate change may alter the prevalence and severity of false springs, our ability to forecast ...
Since Horton in 1965, many authors have sought to aggregate different variables characterizing the state of water into a single value called Water Quality Index ( WQI ). This index is intended to facilitate the operational management of water resources and their allocation for different uses. Detailed and operational description of the main WQI cal...
The quantification of ozone by SIFT-MS was investigated in conditions suitable with an industrial emission context (high ozone demand, dry air/oxygen as manufacturing gas of ozone generator and high humidity levels beyond saturation at room conditions). Ozone reacts with four negative precursor ions available in the SIFT-MS device (NO2-, O2-, HO- a...
Ainsi, dans ce projet de stage, le sujet d'étude s’est porté sur les vitesses de déshydratation des feuilles et de réhydratation des tissus clés impliqués dans la survie et la récupération d’une espèce prairiale à un stress hydrique sévère, le Dactyle aggloméré. Cette étude a pour but de comprendre les mécanismes hydrauliques impliqués dans sa rési...
