From 2006 until the end of 2008, the HCES guidelines, and the concept of a participatory top-down/bottom-up planning approach, were tested in seven different urban and peri-urban sites across Africa, Asia and Latin America. Case studies from four of the seven sites are presented and analysed in this publication.
