The water supply of the population is strongly influenced by the phenomenon of seasonal contrast in the commune of Dassa-Zoume. This study analyzes the endogenous water supply strategies of the population against those contrasts in the commune. The data pluviométriques to collect to the ASCENA of 1954 to 2015, then demographic gotten to the INSAE are used in the setting of this research. They have been completed by the socio - anthropological information gotten by the documentary research and the investigations of land tracks by questionnaire in 200 households chosen The Factorial analysis of the Correspondences (AFC) achieved in the software Minitab and the FFOM model) permitted to analyze the gotten results. It results from the statistical processing and analysis of data collected an increase of average temperatures and declining of rainfall from 353.9 mm in 1995 to 1514.18 mm in 2010, a reduction of rainy season, a prolongation of the dry season. In response to these climate changes, 52 % of households use well water, 22 % water drilling, 9 % water alveolar pots and 17 % use surface water. Other strategies are needed to address this challenge: the optimal water management available, the application of IWRM, water purification and wastewater reuse, use of impluviums.
