Abstract

[fre] La capacité des systèmes agraires africains à supporter des populations rapidement croissantes fait débat. Pour y contribuer, un modèle a été construit à l'échelle d'un village en zone cotonnière et utilisé de façon recursive. Le maximum de l'information disponible sur la zone a été incorporé. Les simulations mettent en évidence un seuil majeur avec la disparition des jachères et la nécessité de mettre en œuvre toute une gamme de techniques pour améliorer la gestion des sols et de la matière organique ; moyennant quoi, un régime de croisière pourrait être atteint avec quatre fois plus d'habitants mais un revenu par tête divisé par deux. [eng] Medium and long term viability of the agrarian system of a village in soudano-saheuan Africa. the case of Bala in Burkina Faso . Can african agrarian systems carry on rapidly increasing populations ? To contribute to this debate, a model has been built at the village level in the cotton zone and is used in a recursive way. The maximum of the available information on the zone has been incorporated. Simulations show a crucial threshold when fallow desappear and when it is necessary to combine different techniques for a better management of the soils and of the organic matter ; doing so, a permanent regime could be reach with four times more people but with half the revenue.
