Résumé
Urban gardens are gaining increased attention among researchers discussing food sovereignty and alternative food production. Kibera in Nairobi, Kenya, is the largest high-density urban area in Africa, in which urban gardens could positively influence citizen’s majorly low dietary diversity. Observations on diversifying effects on citizen’s diets in relation to Kibera’s urban gardens are still missing. Using a quantitative approach with a total sample size of n=103, this study aims to find out differences in dietary diversity, food-related informational content, and motivation to change dietary behaviors between participants and non-participants in urban gardening practic-es. With the help of individual dietary diversity scores, the study found trends towards higher diversified diets among urban gardening participants. Participants also turned out to be better informed, using more informational resources and having a higher willingness to share food-related knowledge with their peers. Trends connecting a higher food awareness and dietary self-assessment to dietary changes were found among participants as well. Apparent differences were not found in motivational drivers to change dietary behavior. This thesis gives a first insight into the importance of urban gardens and their capability to stabilize and improve the dietary sit-uation within Kibera. Continuous research on spill-over effects and motivational factors towards dietary changes will be inevitable to understand further the socially complex dynamics of Kibera’s urban gardens.
