Gum arabic production in Sudan has developed over the years in a well-established traditional bush-fallow system in which the gum tree (Acacia senegal) is rotated with annual crops. Following the Sahel drought, the gum area has suffered from deforestation and gum production has declined. Several programs have been developed to stimulate gum production; however, many original adopters have disadopted gum production and the bush-fallow system. In this paper we apply a logit model to study the decision-making behavior of farmers in west Sudan and to identify the socio-economic factors influencing disadoption of gum production and gum agroforestry system. Variables that measure farmer¿s wealth were found significant in explaining the disadoption behavior. Off-farm work was also found to positively influence the disadoption decision. Results show that a higher level of income from annual crops decreases the probability of disadoption, which suggests that annual crops and gum production do not compete but rather complement each other within the farm household economy. Therefore, policy measures aiming to boost the production of annual crops in the region might reduce seasonal labor migration and accordingly stimulate gum production.
