| Although the majority of Bank projects have been limited to certain areas within cities, the need to have an impact at a city-wide or national level is critical in the face of the alarming rate of growth of slums in many countries. The thrust of the Bank's approach to upgrading is to help cities and governments mount programs to a scale commensurate with the size of the problem.
Scaling up has been tried in a few projects (not necessarily Bank-financed) and some of these experiences have been documented.
An
emerging issue in urban upgrading is the conservation of historic sites
which, due to neglect, have become run-down and evolved into
low-income or slum areas. Recently, some efforts have been made to
combine upgrading of slums in such areas with a view to conserving
their cultural heritage. |
