This thesis assesses historical hydroclimatic conditions over Burkina Faso by integrating land surface modelling, data assimilation and climate change. Hydroclimatic simulations from the Interactions between Soil, Biosphere, and Atmosphere (ISBA), the global Land Data Assimilation System (LDAS-Monde) and the Regional climate Model (RegCM4) under RCP4.5 and RCP8.5 scenarios are used. The results show a good performance of ISBA and LDAS-Monde to monitor historical hydroclimatic parameters. In addition, future climate conditions will substantially threat water resources availability in the country. Therefore, governmental politics are needed to design response options to cope with the problems posed by the projected climate change for the country.
