Sedimentary evolution and ecosystem change in Ahémé lake, south-west Benin / Water quality and sediment transport issues...
Tropical moist ecosystems, such as Ahémé lake, south-west Benin, are increasingly marked by water degradation, linked with the activities of increasing riparian populations. The objective of this study is to analyze sedimentary dynamics and its influence on the changing ecosystem of Ahémé lake from 1961–2010. Data used to carry out the study are re...
Influence of inherited paleotopography and water level rise on the sedimentary infill of Lake Ossa (S Cameroon) inferred...
Lacustrine records hold considerable archives providing access to valuable information. However, to decode this information it is necessary to know how the lake in question and its catchment area function. In this study we propose to highlight the different factors that govern sedimentation by studying different core samples covering the Holocene t...

Tracking land-cover changes with sedimentary charcoal in the Afrotropics
...
Fires have played an important role in creating and maintaining savannas over the centuries and are also one of the main natural disturbances in forests. The functional role of fires in savannas and forests can be investigated through examining sedimentary charcoal in order to reconstruct long-term fire history. However, the relationship between ch...
Palynological evidence for gradual vegetation and climate changes during the african humid period termination at 13°N fr...
Located at the transition between the Saharan and Sahelian zones, at the center of one of the largest endorheic basins, Lake Chad is ideally located to record regional environmental changes that occurred in the past. However, until now, no Holocene archive was directly cored in this lake. In this paper, we present pollen data from the first sedimen...
