World Water Quality Alliance African Use Case Study – Lake Victoria and Volta River Basins

United Nations Environment Programme ; World Water Quality Alliance (2021)

The central aim in the initial WWQA Africa Use Cases is the integration of in-situ and remote sensing-based Earth Observation and water quality modelling data to derive the best possible current state of water quality combined with a multi-stakeholder driven process defining demand for water quality services. The ultimate objective was to provide an evidence base that links water quality hotspots to solutions and investment priorities. These results emanating from this approach are due to be shared widely with the World Water Quality Alliance partners for further consideration and illustration of the approach. This technical summary summarises the stakeholder engagement process, data availability, and identification of water quality products and services to address the problems identified through the stakeholder engagement and data assessment process in the Lake Victoria and Volta Basins. It concludes with summarizing some of the main limitations encountered when trying to access data, and with lessons learned and recommendations regarding the way forward. The full report provides details on these various stages and presents the data collected on water quality and used for the Use Case.
