Du ciel étoilé à l’environnement nocturne, la construction d’un nouveau front de protection de la nature. Éléments de cadrage et approche critiq…

2019

International audience; Des Réserves internationales de ciel étoilé à la "Trame noire", la mise en protection de la ressource obscurité revêt des déclinaisons plurielles (socioculturelles, écologiques et sanitaires) et s’incarne dans des démarches dont les méthodologies sont parfois encore peu éprouvées. Elle n’en est pas moins un sujet bénéficiant d’un réel effet de mode. Qu’on la qualifie par la perte de patrimoine, la dégradation d’habitats, les effets perturbateurs voire destructeurs sur les espèces, ou bien la construction potentielle de ressources pour l’action collective locale, l’appropriation de cette thématique de protection par les réseaux d’aires protégées est pl…

On the use of geophysical methods to characterize heterogeneities of quaternary alluvial deposits. Application to stormwater infiltration.

2007

Colloque avec actes et comité de lecture. International.; International audience; Stormwater infiltration basins are generally built on geological formations with large values of hydraulic conductivity. Such is the case for quaternary alluvial formations, among which are glaciofluvial deposits. Two geophysical investigation methods, namely ground-penetrating radar and electrical tomography, were tested on an infiltration basin built on a glaciofluvial deposit. Geophysical profiles were calibrated on a trench wall dug in the glaciofluvial formation. A sedimentological study coupled to geophysical measurements behind the trench wall highlights the three-dimensional architecture of the deposit…

Impacts de l'occupation du sol sur les ressources en eau du complexe Mono-Couffo (Afrique de l'Ouest)

2009

International audience; En Afrique de l'ouest en général et au Bénin comme au Togo en particulier, les cours d'eau sont des pôles particulièrement attractifs pour la population du fait de la diversité des activités socio-économiques qu'ils permettent. Mais, les variations pluviométriques et la pression humaine de ces dernières années, sur le complexe Mono-Couffo ont eu une influence négative sur les ressources en eau et les écosystèmes en particulier. Les données utilisées sont : la pluviométrie, les débits (Athiémé et Lanta), la superficie des unités d'occupation du sol, la turbidité, le taux de dépôts solides (TDS) et la production halieutique. Ces données ont permis d'analyser d'une part…
