Systèmes de production rizicole et maladies parasitaires dans l'Afrique de l'Ouest : caractéristiques socio-économiques des ménages agricoles en zone de forêt ivoirienne

This study is the continuation of a study led in the savannah area. Its purpose is to describe the economic situation of households subject to malaria risk in Côte d'Ivoire forested region, so as to provide economic indicators which could eventually help explain the expected differences in malaria morbidity. A survey was conducted beside a sample of nearly 800 rural households concerned by three different farming systems (inland valleys without rice cultivation, inland valleys with no or partial water control suitable for one annual rice crop, and inland valleys with full or partial water control suitable for two rice crops per year). This survey allowed to collect economic data such as the different cultivated crops, incomes and malaria prevention expenditures. Monetary economy is based on coffee and cocoa; rice and cassava being the main food crops. If some economic differences between the three agroecosystems were observed, those differences are not so great as in the savannah area and only concern revenues: value of property accumulation is low and quite similar in the three agroecosystems. Only 34% of families used bed nets and it was mainly for the family's head and his wife. Other means of protection against mosquitoes were used by 37% of the families. For those, the monthly average expenditure was about 1000 Fcfa.
