GEOV1: LAI, FAPAR essential climate variables and FCOVER global time series capitalizing over existing products. Part 2: Validation and intercomparis…
2013
International audience; This paper describes the scientific validation of the first version of global biophysical products (i.e., leaf area index, fraction of absorbed photosynthetically active radiation and fraction of vegetation cover), namely GEOV1, developed in the framework of the geoland-2/BioPar core mapping service at 1 km spatial resolution and 10-days temporal frequency. The strategy follows the recommendations of the CEOS/WGCV Land Product Validation for LAI global products validation. Several criteria of performance were evaluated, including continuity, spatial and temporal consistency, dynamic range of retrievals, statistical analysis per biome type, precision and accuracy. The…
E-learning in adult education : the prerequesites to change
2018
Our research deals with the relationship that training organizations’ actors, as providers, maintain with e-learning. When the market and expectations seem favorable, that employees (to a lesser extend job-seekers) often face availability, mobility and homogeneity constraints, that the needs for a minimum number of participants in order to (economically) allow the training are sometimes hard to reach, that the knowledge and objectives of each - just like the meaning given to effort - are diverse, that a fast reactivity in front of the emergency of the training needs is a more and more expected requirement in Continuing Professional Education (a very competitive field), its actors do not ful…

Climate change impact on the West African monsoon from June to October.
2015
Sixteen CMIP5 models are used toanalyse how climate changes over the West African Monsoon region between a “future period”, defined from 2031 to 2070under the rcp4.5 emission scenario, and the “current period”, defined from 1960 to 1999 under the historical emissionscenario. The results show an increase of the September to October rainfall amounts. Circulation anomalies include of anincreases of sea-level pressure over the Mediterranean Sea and Europe that allow a strengthening of the moisture flux fromEuro-Mediterranean regions into the Sahel. These changes are stronger in autumn.

Les changements climatiques : approche conceptuelle comparée en sciences humaines et sociales
2015
National audience; La présente proposition a pour domaine de recherche principal une approche des changements climatiques en droit public. Elle vise également à observer la traduction des instruments existants dans une perspective historique.Les notions théoriques relatives aux changements climatiques sont nombreuses et désormais bien identifiées : vulnérabilité, résilience et adaptation notamment. Si elles sont employées par le plus grand nombre, leur définition est moins aisée en sciences juridiques, où la référence se fait davantage en termes de prévention et de précaution. Néanmoins, l’instrument communémentutiliséen droit de l’environnement, en droit de l’urbanisme et dans les autres c…
The climate change effect on the african monsoon region : evolution of the precipitation and atmospheric fields in the CMIP3 and CMIP5 simulations un…
2013
The fourth IPCC report in 2007 established the synthesis of previously published work onthe effects of climate change on global and regional scales. It shows in particular that no consensuscan be found with regard to the future of rainfall — and atmospheric dynamics- associatedwith region — African monsoon. This dissertation revisits this issue in the light of new dataand using an approach avoiding over-representation of the number of simulations available forone type of model and taking into account the diversity of models and their evolution in time :twenty general circulation models (GCMs) participating in the exercises CMIP3 (twelve GCMs)and CMIP5 (eight GCMs) under the A1B emissions sc…
L'agriculture urbaine : une agriculture juridiquement comme les autres?
2019
International audience; En plein essor, l'agriculture urbaine se présente comme un défi pour le droit agricole, construit sur un paradigme géographique et sociologique : la ruralité. Dès lors, comment saisir juridiquement ces nouveaux projets productifs, aux formes variées et aux modèles économiques souvent hybrides ? Est-ce aux acteurs urbains de s'adapter à des règles venues d'ailleurs, ou au droit de se tordre pour accompagner le mouvement d'une agriculture des villes, qui questionne celle des champs ?
