In the context of environmental and socio-economic changes, sub-Saharan African countries will have to ensure their food security, while reducing its environmental footprint. It is assumed that to take up the challenge of climate smart agriculture, it is necessary to intensify ecological processes of agrosocioecosystems at the scales of the soil-plant system, the farmers' fields and the agro-ecosystems and also the territories. This ecological engineering approach is the framework of the researches led by the IESOL International Joint Laboratory "Intensification of agricultural soils in West Africa". For instance, studies concerning the management of organic matters and the nutrients cycles in peri-urban agriculture and in Pearl Millet cropping systems will be exposed. We tested intensification practices as crop livestock integration, urban waste recycling, more efficient fertilizer use, and degraded lands restoring in Senegal and Burkina Faso. This will lead us to propose some rules of thumb of future innovations in semi-arid agrosystems based on the recycling and the conservation of organic matter and nutrients. (Texte intégral)
