Dar es Salaam is one of the fastest growing cities in theworld. More than 70% of the residents live in informal settlements.Many of them are located in flood prone areas like river valleys andfloodplains, which flood annually. Because of their limited coping capacity,residents are not able to recover from the impacts of this flooding.Due to the change of precipitation patterns, the flood risk islikely to increase in the future, putting even more people and assets atrisk during more frequent and intense floods. This graduation projectseeks to answer the main research question: How can urban formand landscape help to mitigate the effects of floods on citizens in Dares Salaam, Tanzania?For areas with a high density of buildings, multifunctional courtyardsare proposed. The existing building structure is strategically densified,and filled with new buildings to shape courtyards. Inside, a variety ofinterventions reduce the water run-off into the river valley, treat wastewater and generate income via urban agriculture and aquaponicsystems. For the river valley the construction of “chinampas” is beingproposed, which creates a high retention capacity for storm waterwhile enabling agricultural activities and connectivity across the rivervalley throughout the wet and dry seasons. At the edges of the valley,different interventions are located in order to reduce and cleanrun-off water before entering the valley. The combination of spatialinterventions to reduce the flood risk with urban agriculture reducesthe impacts and increases the ability of residents to deal with futurehazards.The design proposals are supported by a implementation strategyand complimenting policies which reduce pollution, steer future urbandevelopment and introduce new renting models to host a higher diversityof lifestyles with different economic abilities.
