Little attention was given either to the development of appropriate institutional structures and processes for urban management, or to the handover to ongoing administration, by the World Bank during the first decade of implemen- tation of its new approach to improving residential conditions for low-incom urban residents. Today, much more attention is being given both to the issue of an appropriate allocation of responsibility for the tasks of urban management between the public and private sectors and between different forms of organisa-tion, and to the immediate needs of post-project operation and the maintenance o services and infrastructure. This paper attempts to add to the discussion of these issues by analysing the case of Lusaka, where a partly World Bank funded project to upgrade a large proportion of existing unauthorised areas and provide new serviced plot areas was implemented between 1974 and 1981
