Description
Summary:This article discusses experiences of applying the source-to-sea approach, contextualized to source-to-lake, in the Lake Hawassa sub-basin of the Ethiopian Rift Valley, particularly for the purpose of generating in-depth knowledge on sediment flows, building a geographically relevant comprehensive stakeholder and governance analysis and using this to design impactful interventions that can reduce sediment flux into Lake Hawassa. The source-to-sea approach has proven to be a useful and flexible for evaluating sediment management in the context of a sub-basin such as that of Lake Hawassa.
