Abstract
English: This article is based on the assumption that more spatially efficient investment
choices in both economic and basic infrastructure spending can make a significant
impact on the equity, efficiency and sustainability of human settlements. Emerging
from work conducted as part of a Department of Science and Technology (DST)-
funded Integrated Planning and Development Modelling (IPDM) project, the article
argues that decisions about infrastructure investment in South African metropolitan
areas ought to be grounded in robust and rigorous analysis and scenario evaluation.
More evidence, and better evidence, an understanding of spatial trends and the
underlying forces that shape them, are needed to support planning and infrastructure
investment. Urban simulation platforms offer valuable tools in this regard. Findings
of simulation work in three metropolitan areas (eThekwini, Nelson Mandela Bay and
Johannesburg) are presented to demonstrate this, and some implications for spatial
policy, planning and infrastructure investment are highlighted.
Afrikaans: Die artikel is gebaseer op die aanname dat ruimtelik-effektiewe beleggingkeuses in beide ekonomiese en basiese infrastruktuurbesteding ’n beduidende impak op die gelykheid, effektiwiteit en volhoubaarheid van menslike nedersettings kan hê. Werk wat gedoen is as deel van die Integrated Planning and Development Modelling (IPDM)-projek, en befonds is deur die Departement Wetenskap en Tegnologie, argumenteer dat besluite omtrent infrastruktuurinvestering in Suid-Afrikaanse metropolitaanse gebiede gegrond moet word in robuuste en grondige analise en scenario evaluering. Meer bewyse, asook beter bewyse, sowel as ’n begrip van ruimtelike tendense en hul onderliggende kragte is noodsaaklik om beplanning- en infrastruktuurinvestering voldoende te ondersteun. Stedelike simulasie platforms bied waardevolle instrumente in hierdie verband, en bevindinge omtrent simulasie werk wat gedoen is in drie metropolitaanse gebiede (eThekwini, Nelson Mandela Baai en Johannesburg) word voorgelê om dit te demonstreer. Sommige implikasies vir ruimtelike beplanning, beleid en belegging in infrastruktuur word ook uitgelig.
