Doing drainage differently: Tackling urban flooding in the future mega-city of Dar es Salaam, Tanzania
Every year floods in the Msimbazi River Valley in Dar es Salaam result in deaths and millions of dollars of infrastructure and economic losses. The Msimbazi Valley is a strategically important area in the city. Two of four of Dar es Salaam’s main traffic arteries cross the main flood plain; communities at the lower reaches of the river depend on close access to Dar es Salaam’s central business district for their livelihoods; and the river catchment includes significant environmental assets, including protected forest areas, wetlands and mangrove forests.
The session will present a comprehensive participatory driven, scientifically validated, and economically verified approach to manage flooding, improve mobility, reclaim land and protect the environment. The presenters will showcase a nearly two-year long process of developing a blueprint for the regeneration of 400 hectares of land located in the Central Business District of Dar es Salaam. This blueprint is a product of a consultative process that brought together more than 250 stakeholders from 59 institutions; and was informed by an extensive data collection, modeling and technical studies. The session will also share a real estate market analysis for residential, retail and office space and the overall economic benefits of this comprehensive regeneration and creation of the largest urban park in the region.
