In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis, fertiliser trials were carried out at sites distributed along the bioclimatic gradient in the Gourma (Mali) over contrasting rainfall years between 1988 and 1992.

This study identifies the causes of the observed differences in flock productivity in a central Malian village, in a rainfed millet agropastoral subsystem. Small ruminant productivity, management factors and socio-economic characteristics are analysed. The causes leading to the observed differences in small ruminant productivity are related to the owner's socioeconomic characteristics, to his management strategies or to preferences for one or the other small ruminant species.

This paper deals with foraging behaviour of cattle grazing semi-arid rangelands in the Sahel of Mali. It discusses the location of study site, vegetation in the grazing orbit, herd management and livestock behaviour. Results on seasonal variation in feed supply, selection of the annual grazing orbit in accessible land and of the daily route in the grazing orbit, selection of herbage mass patches within landscape units and selection of species are also presented in the paper.
