The Hungry Cities Partnership Report No. 11: The State of Household Food Security in Nairobi, Kenya is published. The report was authored by Samuel Owuor. It presents the results of a city-wide household food security survey of 1,434 Nairobi households, conducted by the Hungry Cities Partnership and the University of Nairobi. As the first city-wide survey of household food security in Nairobi, this report provides researchers and policy-makers with detailed data and information about the overall food security picture in Nairobi, as well as important insights into the operation of the city’s food system. In particular, the report demonstrates the central importance of the informal food sector, which will be explored in greater detail in the next HCP report on Nairobi.
