Part 5: Economic risk of hydropower dependency

The Zambezi River Basin is highly vulnerable to the negative effects of climate change. Increasing water scarcity due to increasing temperatures and evaporation, decreasing rainfall, and a dramatic reduction in mean annual runoff are predicted before the end of the century. These hydrological changes will fundamentally alter the economic benefits and risks associated with river management, including existing and future hydropower development, and the valuable ecosystem services sustained by river flows. Cumulatively, these economic risks require a careful reconsideration of the future dependency on hydropower development in the basin.
