Msimbazi Valley in Dar es Salaam, Tanzania, floods yearly. But despite this frequent flooding, many people still live in makeshift settlements in the valley. This decision exposes them to life-threatening floods and flood-related health hazards such as diseases including cholera and dysentery.
Adaptive strategies
Msimbazi residents have a wide range of community-based strategies to reduce flood risk. These include temporarily relocating to the public institutions present in the neighbourhoods such as schools, communicating flood warning information to others, for example the level of water upstream, cleaning canals to release flood water into the Msimbazi River, constructing houses with strong foundations to withstand floods, and building landfills along house walls to raise the level of walls and windows. Tree planting is also done to prevent soil erosion.
