Résumé
The organization of farm management in Ferlo opens with wage labour, confirming the monetisation of the Sahelian system of transhumance. Today, 25% of the pastoral exploitations of Ferlo resort to wage-labour for various reasons: needs for the production management in general and small ruminant in particular, social status of the stockbreeders and improvement of the living conditions. In return, the wage-labour improves the incomes of the encampments, attenuates the risks of conflicts, helps the employees to constitute their own livestock, and contributes to the durability of the way of life and the production of the pastoral societies. Individual choice at the beginning, the wage-labour leads to the collective protection of the exploitations, but does not erase social pattern of production. Therefore many differences remain between types.
