Knowledge partner:

According to this study, water abstraction and reservoir building in the upstream countries are expected to reduce and/or redistribute the available flows for the Okavango Delta ecosystem. To study the impacts of upstream and local interventions, a large-scale (1-km2 grid), coupled surface water/groundwater model was developed. Scenarios were designed to study major upstream and local interventions and their expected impacts in the Delta. The scenarios" results can help decision makers strike a balance between environmental and human water demands in the basin.
