Après l'édification des barrages sur le fleuve Sénégal, l'agriculture irriguée devait progressivement remplacer l'agriculture de décrue dans la moyenne vallée. Néanmoins, lorsque la crue est d'ampleur suffisante, on observe encore des cultures de décrue dans le lit majeur. Cette étude, réalisée entre juin 2016 et décembre 2019 dans la cuvette de Po...
In Sudano-Sahelian agriculture, organic amendments are often limited by resource availability. Small branches (ramial wood, RW) represent an organic resource found in many landscapes but little is known about their effects. This field trial (2007–2009) studied the effects of RW or straw at low application rate (0.69 Mg C ha−1 year−1) on topsoil car...

Busseola fusca (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. One century after its first description by Fuller in 1901, inaccurate information based on earlier reports are still propagated on its distribution (e.g., absent from the lower altitudes in East Africa) and host plant range (e.g., feeding on a l...
Landscape ecology is a discipline that has shown an increasing interest to understand certain pest problems and their control by natural enemies in temperate climate. In Benin, in a very different climatic, social and economic context compared to Europe, this approach was carried out in two lowland rice cropping systems during the rainy season, wit...
Un grand nombre de sorghos sont ou ont été la propriété de groupes particuliers, jumeaux ou de cercles d'individus ayant commis des faits de bravoure. Plus souvent il s'agissait de sorghos liturgiques attachés à certains cultes ou à leurs desservants ou encore des sorghos de chefferie. Dans les monts Mandara, ces sorghos sont révélateurs d'un contr...

Nous avons fait le pari de remonter le temps d’une histoire du manger et du boire dans les monts Mandara. Île montagnarde plantée dans le bassin tchadien, elle a enregistré les diffusions de plantes en décalage par rapport aux plaines environnantes, mais par conservatisme ses populations en ont entretenu plus longtemps la culture. Ce milieu contrai...
