The city-region’s legacy of spatial segregation,<br />

sprawling housing development, and insufficient<br />

public transportation coverage creates inefficiencies<br />

that slow economic growth. As the Gauteng<br />

City-Region Observatory has clearly documented, the<br />

city-region’s physical growth patterns have followed<br />

the apartheid spatial framework. 87 While exceptions<br />

exist, much of the growth in the recent decades<br />

has been on the fringes of the city-region, where<br />

land is cheaper. 88 The province’s share of urbanized<br />

land grew by 45 percent between 1991 and 2009. 89<br />

Population density varies significantly, from 3,067<br />

inhabitants per square kilometer in Johannesburg<br />

to 475 in Tshwane. Overall, the Gauteng City-Region<br />

is less dense than most of its comparison regions,<br />

although Johannesburg’s density level exceeds that in<br />

all peers except Shenzhen. Coordinating transportation<br />

investments with higher density residential and<br />

commercial development—as is being done with the<br />

City of Johannesburg’s Corridors of Freedom initiative<br />

and the province’s expansions of bus rapid transit and<br />

cite lack of transportation as a significant barrier<br />

to employment. 91<br />

➤ BOTTOM LINE: International infrastructure connections in the Gauteng City-Region are relatively<br />

well-developed. South Africa’s freight and logistics systems rank in the middle of their peer group, but exporting<br />

costs remain relatively high for firms. The O.R. Tambo International Airport has positioned the city-region as<br />

an important international aviation node, offering a comparative advantage for businesses that demand global<br />

access. Local infrastructure can continually be upgraded. Broadband speeds have improved over time, but are<br />

not yet on-par with most global peer cities and remain varied across communities. Continuing to align transportation,<br />

new housing development, and land use policy to increase density along key corridors and nodes can<br />

help improve spatial efficiency in the city-region.<br />
