The Consequences of Past Agricultural Outputs on the Interacti

چکیده
In rural areas of LDCs, because of the existence of market imperfections, health and nutrition status may depend on the levels of specific agricultural productions and not only on the income level. However, these specific impacts have never been studied. We estimate, from a sequential technological model incorporating interactions between health and nutrition, changes in health and nutrition status of autarkic agricultural households in Rwanda which are due to variations in socio-demographic characteristics and in levels of specific crops. The model is supported by several tests. The estimations take into account cluster-fixed effects and the sampling scheme. The food outputs have generally beneficial influences on health and nutrition, while the traditional beers output has a negative impact. A policy based on incentives for substituting cultures may be particularly favourable to the health and nutrition of peasants. RÉSUMÉ Dans les zones rurales des pays en voie de développement, les états sanitaires et nutritionnels dépendent étroitement des niveaux de productions agricoles spécifiques, et pas seulement du niveau des revenus, en raison de l’existence d’imperfections de marchés. Cependant, ces impacts n’ont jamais été étudiés. Nous estimons, à partir d’un modèle technologique séquentiel incorporant des interactions entre santé et nutrition, les changements de la santé et de la nutrition des ménages agricoles autarciques du Rwanda, dus aux variations de facteurs socio-démographiques exogènes, mais également à des variations des niveaux de récoltes spécifiques. Le modèle est supporté par plusieurs tests. Les estimations tiennent compte d’effets fixes pour les grappes et du plan de sondage. Les productions alimentaires ont des effets généralement bénéfiques sur la santé et la nutrition, alors que la production de bières traditionnelles a un impact négatif. Une politique basée sur des incitations à substituer des cultures pourrait être particulièrement favorable à la santé et la nutrition des paysans.
