Cet article montre qu'une lecture des pratiques et des paysages par l'approche des services écosystémiques culturels dans des sociétés traditionnelles se heurte à une incompatibilité des prémisses, celles de l'approche occidentale scientifique étant très différentes de celles des représentations villageoises. La démonstration part d'une pratique de...
Notre objectif est d'évaluer la contribution des arbustes de Guiera senegalensis aux flux d'eau et de carbone dans un parc agroforestier à petit mil (Pennisetum glaucum L.R. Br.) et dans une jachère. Le site expérimental est situé au sud-ouest du Niger, sur un bassin-versant sahélien de 2 km2. À l'échelle de l'arbuste de Guiera senegalensis, le tau...
Increased drought length and intensity is expected in the Mediterranean basin under anthropogenic increase in atmospheric CO2, leading to extreme events not yet encountered in the present climate variability. Understanding ecosystems responses and capturing peculiar ecophysiological processes related to these events have been investigated in the fi...

Because of technical difficulties in measuring soil properties at a large scale, little is known about the effect of soil properties on the spatial distribution of trees in grasslands. We were interested in the associations of soil properties with the phenomenon of tree encroachment, where trees increase in density at the expense of grasses. The sp...

Woody plant encroachment in grasslands is a worldwide phenomenon. Despite many studies, the consequences of woody plant encroachment on sub-canopy vegetation and soil properties are still unclear. To better understand the impacts of trees on grassland properties we examined the following questions using a mountainous sub-tropical grassland of South...
