Thirdly the programmebegan a processofincorporating climate change impactsintolongtermcityplanning. The municipality and CSIRworkedwith the UKbasedTyndallCentre for Climate Change Researchtodevelop a modelenabling the simulation,evaluation and comparisonofstrategicurbandevelopmentplans in lightofanticipated climate change impacts.Helpingtodevelop a deeperunderstandingof the effectsofgreenhouse-gasemissions, the modelwillenablebettertechnicalassessmentofalternativestrategicapproachesto climate change mitigation and adaptation.

A keyrequirementof the compactcityisthatresidential,employment and recreationdevelopmentsmustbeco-located,wherepossiblethrough the developmentofmixedusezones. In thisregard, the city’slandusemanagementsystemis a crucialcomponentof the integratedspatialplanningsystem,ensuringappropriatelandusezones and controlsare in placetoimplementthesemixedusezones.Accordingly, a singlelanduseschemeframeworkisnowbeingdeveloped for the citytoreplace the formerapartheidplanningschemeswhichwerecharacterisedbyurbansprawl,lowdensitydevelopment and fragmentationof the urbanspace.Thisschemewillhelpbegintoimprovehistoricallyunder-investedareas,whichwereformerlyexcludedfromofficialcityboundaries,bringingtheminto a landusemanagementsystemwhichensurestheirappropriate and sustainablemanagement.Aligningwith the hierarchyofplans, the singlelanduseschemewillsupportgreaterintensityofurbanlanduse and offermoreopportunity for sustainablelifestylechoices. For example,betterprovisionofinfrastructure for cycling and walking,offeringpotential for reductions in airpollution and greenhousegasemissions. In thisway and in others,anintegratedlandusemanagementsystemcanbeplay a keyrole in mitigating the city’simpactonglobal climate change.
