This thesis is based on qualitative research that explored the food system which feeds most of the over 4.6 million residents of the fast-growing city of Dar es Salaam in Tanzania. The researcher followed key foods (maize, rice, potatoes, green vegetables, eggs and milk) from the urban eaters to the retailers, processors and primary producers.
What has been found is a “symbiotic food system” made up of multitudes of small-scale and interdependent actors that together produce the food and get it to urban eaters at a city feeding scale. They do this without any vertically - or horizontally - integrated corporate structures.
The symbiotic food system that feeds Dar es Salaam is not perfect, but it is working and worthy of further research and interventions to create a more enabling environment for such foods systems to flourish in Tanzania and elsewhere.
I have published several blogs based on my PhD research that are available online.
