In Benin, annual water availability per capita far exceeds the critical threshold of about 1,700 m(3), but during the dry season, water scarcity occurs at the local scale. By modeling the water balance of the Ou,m,-Bonou catchment with WEAP (Water Evaluation and Planning System), this study aimed at analyzing Benin's future water situation under different scenarios of socio-economic development and climate change until 2025. The results show that the pressure on Benin's water resources will increase, leading to greater competition for surface water. Furthermore, financial and technological constraints hinder a satisfactory development, and exploration of groundwater and reservoir resources. However, improvements are most needed, especially in rural areas. Decreasing inflows and groundwater recharge due to climate change aggravate this situation. Even though there are uncertainties and constraints concerning the model and input data, this study shows that the WEAP results offer a solid basis to assist planners in developing recommendations for future water resource management by revealing hot spots of action.
