Tanzania's Dar es Salaam city struggles to cope with rapid expansion, fend against climate chan

The city of Dar es Salaam in Tanzania is one of Africa's fastest-growing cities. But rising sea levels, ineffective waste management and poorly coordinated urban planning are threatening the city's fragile infrastructure and putting in peril the lives and livelihoods of its people. Dar es Salaam's history of flooding is in part due to inadequate and ageing infrastructure, its low-lying geography and the Msimbazi river that flows right through the city. Daniel Kijo reports.
