The aim of this review is to identify knowledge gaps and provide appropriate
background material for a proposed full-scale study of market institutions and urban food supply across Nigeria and Zambia. The paper was prepared in draft form prior to pilot field studies with local collaborators in Jos, Nigeria, in January 2004, and in Lusaka, Zambia, in February/March 2004. It thus helped to guide both those pilot field studies and also the discussion at the workshops for policy makers, academics and practitioners subsequently held in Abuja and Lusaka. It has since been extended with additional grey literature accessed during the country visits.
