Zambia in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Zambia rose steadily. To get a sense of how street development has changed in Zambia, we can consider three of its most populous regions: Lusaka, Copperbelt and Southern. Out of the three regions, Lusaka and Southern do not follow the same trend as the country. The level of street-network sprawl in new development in Lusaka followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Southern followed a zig-zag trend with an overall increase.
The largest city in Zambia is Lusaka, with a population of 2362700 people. Taking into account the entire (i.e. aggregate) street network in Lusaka as of 2020, the overall level of street-network sprawl is 3.15, which is moderately connected. The level of street-network sprawl in new development in Lusaka followed a zig-zag trend with an overall increase.
Zambia in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Zambia is Chilanga with an SNDi of 4.95, which is very sprawly. Conversely, the most connected city is Mbala with an SNDi of 1.82, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Mbala, Chilanga.
