Impacts Socioéconomiques Et Sanitaires De L’exploitation Agricole De La Plaine Inondable Todé- Gbamè Au Bénin

The present study aims to determinate the prevalence of the diseases linked to the agricultural exploitation of Todé-Gbamè plain liable to flooding in Benin and to assess the related work wasting times. To reach the study’s objectives, sanitary, economic and social investigations were conducted with the farmers and health workers of the Commune of Adjohoun. Inquiry was also based on agronomic trial regarding maize yield in the plateau and the plain liable to flooding. The study revealed that soils fertility and farmers income are higher in the plain than that of the plateau. Moreover, the annual prevalence of diseases are globally high in the plain liable to flooding, followed by both plain and plateau and finally by the plateau with the paludism at the top and present at 100% in the three areas. Then, we have respiratory infections, gastroenteritis and dermatosis with a remarkable presence in the plain and both plain and plateau. Finally, the dermatosis was not recorded in the plateau. Consequently, the annual loss working days due to diseases were globally high in the plain liable to flooding, followed by both plain and plateau. With regards to this critical situation, the main identified causes are cropping practices and less advisable farmers’ behaviors in Todé-gbamè’s plain liable to flooding. That is why; it is urging to enhance the technical capacities of the farmers of the study area through a subsequent trainin

Flood Hazard Assessment in Agricultural Areas: The Case of the District of Pélébina in the Municipality of Djougou, Bénin

Flood is a natural disaster and causes loss of life and property destruction. Its impacts are large on agriculture especially in West African countries where smallholder farmers account for 80% of all the farms. The objective of this study was to assess flood risks in the inland valley of Dosir located in the district of Pélébina, northern Benin. Rainfall, discharge and water level in the riverbed were monitored using rain gauge, acoustic current meter and pressure sensors, respectively. The hydrological functioning of the inland valley was simulated using the Integrated Flood Analysis System (IFAS) model. The calibration was done based on the land use map (GlobalMap) and the soil water holding capacity map (UNEP). Our study demonstrated the existence of a high flood hazard in the inland valley of Dosir which reacts very quickly to rainfall solicitations. The IFAS model has shown a good performance in simulating the runoff in the riverbed of the inland valley with a coefficient of determination of 0.65. The IFAS model can be used to design a flood management system in the district of Pelebina. Further studies are needed to assess the exposure and vulnerability of farmers to flood risk
