Two country representatives from almost 10 countries are expected to attend the conference one from the operational sector and one from the academic field. Country representatives are requested to present water related issues and existing data systems and data exchange Case studies of global water cycle observation and evaluation will be highlighted. Existing meteorological and hydrological networks will be presented and Needs for solution, on-going and/or planning approaches will be addressed. Expectation to earth observations, predictions, data integration and modeling will be discussed. Poster session aims at presenting and exchanging ideas and experiences of the African water cycle investigations at different time and space scales in different African regions. It will help network building between African representatives and meeting participants. Poster presentations will deal with Data systems and decision support tools related to the African water cycle observation, analysis, and prediction as well as forecasting. Issues will be related to :

• Precipitation variability
• Water balance, hydrodynamics and hydrological processes, scales
• Evapotranspiration and soil moisture modeling, including using remote sensing
• Regionalization approaches
• Network optimization
• Hydrological forecasting in data sparse conditions
• Flood and drought risk management
• Global Water Systems

Introductory presentations on GEOSS and water-related international projects in Africa are scheduled. Summarizing the water-related science update, the country reports and the international activities introduced in the previous sessions, discussion on directions for cooperation and coordination toward solutions for water related common issues in Africa is scheduled.
