Chapter 32: A GIS-based planning support system for inclusionary housing profitability optimization in Cape Town, South Africa
South African urban centres are characterized by deeply entrenched racially operating spatial inequality; primarily a consequence of the apartheid legacy. Democratic-era, formal-housing delivery programmes on peripheral land have reinforced these patterns. In addition, gentrification of the few remaining affordable central precincts, exacerbated by urban renewal programmes, has further displaced poorer urban communities. To halt and ideally reverse this trend, for the past decade, national and municipal authorities have attempted to introduce inclusionary housing policies. The consideration by such policies of spatial factors that influence financial viability of inclusionary housing development projects, has proven challenging. The ease and rigour of decision-making at both policy and implementation levels could be enhanced by a geographic information system (GIS)-based planning support system (PSS) that is capable of analysing both spatial and non-spatial factors on multiple land parcels. In this research, such a PSS is evaluated through the consideration of five sites in central suburbs of Cape Town.
