Alluvial sedimentary archives contain important geochronological and paleo-environmental information on past geomorphic processes in semi-arid regions. For North Ethiopia in particular, flashflood sediments transported by ephemeral streams can provide interesting chronological information on Late-Holocene land degradation, whether or not impacted by climate or land cover changes upstream. Here we...
Vegetation cover changes in African drylands are often thought to result from population growth, social factors and aridification. Here we show that long-term vegetation proxy records can help disentangling these main driving factors. Taking the case of North Ethiopia, we performed an integrated investigation of land cover changes over the last four centuries around the endorheic Lake Ashenge, as...
