Zimbabwe: Is there a solution to the persisting water crisis in Zimbabwe? I ask Professor Tamuka Nhiwatiwa, a Senior Lecturer at the Department of Biological Sciences, University Lake Kariba Research Station, at the University of Zimbabwe. Tamuka says Harare city in Zimbabwe is built on its catchment area. It relies on treating polluted waters from Lake Chivero and the Manyame River for domestic use.

Also listen to how Kenyan and Seychelles youth are solving the plastics menace. 

Lake Chivero and the Manyame rivers once hosted international fishing tournaments. However, today, these rivers are basically sewerage ponds. Why? Is there a solution to this persistent water crisis?
