Abstract

type="main" xml:lang="fr"> L'article analyse l'impact économique des aménagements antiérosifs sur les exploitations agricoles dans le bassin versant du lac Lagdo au Cameroun. Les aménagements antiérosifs, techniques de lutte contre l’érosion, ont été introduits au Cameroun depuis plusieurs décennies. Aucune évaluation des impacts de ces aménagements dans les exploitations agricoles n'a encore été faite. Utilisant les données d'une enquête effectuée en 2007 et 2008 et un modèle de régression avec changement de régime, l’étude se concentre sur la productivité des facteurs de production dans les parcelles avec et sans aménagements antiérosifs. La comparaison des niveaux de rendement moyen des cultures entre les adoptants et les non-adoptants des aménagements de notre échantillon montre une différence significative qui représente jusqu’à 10% de la valeur de la production agricole. Nous trouvons également des preuves d'un biais de sélection positif qui indique que les agriculteurs avec des rendements des cultures supérieurs à la moyenne sont plus susceptibles d'adopter les aménagements. La présence de ces aménagements dans les parcelles procure aussi un avantage en matière d'accroissement de productivité des intrants. L'approche analytique développée et la conclusion positive du biais de sélection peuvent être pertinentes pour l’évaluation des autres technologies agricoles de conservation des sols diffusées dans la zone.
