Is it possible to improve the traditional grazing management in the flood plain of the Niger river in central Mali?
Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value. High nutrient fee...

Encore une saison des pluies tres deficitaire sur le ranch de Niono (sud Sahel - Mali). Evolution de la vegetation d'une cinquantaine de sites suivis depuis 1976
To document trends in land use and herbaceous production, 71 field sites sampled among cropped fields, fallow fields and rangelands in the Fakara region (Niger) were monitored from 1994 to 2006. The overall trend in land use confirmed the historical increase of the cropped areas since mid 20th ce...
