Abstract: Due to the fast growing urban population and the economic problems, the number of urban poor in sub-Saharan Africa has been rapidly increasing. In order to make ends meet, many poor urban households fall back on farming activities, either within the city boundaries or in the rural areas they come from. The central question raised in this paper is whether access to farmland influences the households' food situation. The results of this exploratory paper indicate that as far as the Nairobi poor are concerned, the question can at least partly be answered in the affirmative.
