For most cities in developing economies, servicing existing
developments is a major challenge, because additional people are flowing
into established squatter settlements daily. This section will address experience
and methods of setting priorities for services to existing development.
It give priority attention to the fact that most people living in low-income
settlements can afford only very basic standards of service, if any at all.
In more developed economies, the most difficult choices arising from action
in existing areas of development may arise in relation to:
- finding shelter for homeless persons;
- locating additional projects next to established areas;
- addressing contaminated sites left from early industrial eras, sometimes
called "brownfield" sites
