Urban sanitation: Assessing the problems and suggesting solutions

The lack of sanitation in slums worldwide is a major health concern and is likely to get worse as rapid urbanisation continues in Africa and Asia. In this first episode of Sanitation Matters, Dr Martin Mulenga, a senior researcher at the International Institute for Environment and Development, discusses the problems and successful projects he has seen in informal settlements across the globe. He also talks about his involvement in the SHARE consortium and the diversity and strength of its partners.
