Hydropower (HP) is the 2nd source of energy in Côte d'Ivoire. However water resource for HP is threatened by climate change (CC). Therefore the hydro potential and production are impacted. This study investigates the impacts of future CC in the White Bandama watershed using hydrological modelling coupled with GIS analysis. It emerges that in the future an upward trend in flows will be recorded. This could contribute to the siltation of dams and an increase in the risk of flooding in the basin.

This study aims to analyse the frequency, intensity and duration of extreme climate events in order to optimise sugarcane production in the Ferkessédougou sugar complexes. This study could enable the Ferkessédougou sugar complexes managers to develop strategies for adaptation to climate change.

In view of the complexity of the phenomenon of water related soil erosion in the Bia catchment area, linked to a large heterogeneity of soils, to a very scattered and in some places non-existent vegetation cover, and to a poorly distributed precipitation in both space and time, a mapping test of the “specific erosion” random variable is undertaken. The mapping of the intensity of the erosion hazard was carried out using the Universal Soil Loss Model (USLE).

Pour résoudre les problèmes d’approvisionnement en eau potable des centres urbains, le gouvernement ivoirien a décidé d’utiliser les ressources pérennes telles que le fleuve Sassandra. Ainsi, le sous bassin du fleuve Sassandra en amont du barrage de Buyo est pressenti pour alimenter les villes de la région du Haut Sassandra. A cet effet des mesures de prévention doivent être prises pour anticiper sur les difficultés que pourrait rencontrer le traitement de ces eaux pour les usages domestiques.
