Irrigation stabilizes agricultural production and hence improves farmers’ living standards and conditions. The permanent presence of water may, however, increase the burden of water-related parasitic diseases and counter the economic benefits of irrigation by reducing farmers’ health. The purpose of this study was to assess the impact of malaria on farm household property, beyond the health risk (studied elsewhere). The research question was: by weakening individuals, does malaria reduce productive capacities and income workers, and consequently limit their property accumulation? To test this hypothesis, we use data on property (farming equipment, livestock and durable consumer goods) and Plasmodium falciparum indicators generated by a study carried out in 1998 in the Ivorian savannah zone characterized by inland valley rice cultivation, with a sample of nearly 750 farming households. Property is influenced by many factors related to the size of the family, the area under cultivation and high parasite density infection rate of P. falciparum. A significant negative correlation between high-density infection rate and the property values confirms that by reducing the living standards of households, malaria is a limiting factor for property accumulation.
