Why a settlement starts here
Site factors explain why a settlement started in a particular place: water, transport, minerals or a harbour. Johannesburg came into being because gold was discovered; Durban and Cape Town grew because they are harbours.
- Towns arise at crossroads: transport brings trade and people. A town on a national road grows from passing traffic.
- A mining town grows around a mine; a market town is where farmers buy and sell goods.
- A town declines when its main industry closes; young people leave for work and study.

The shape of settlements
| Pattern | What it looks like |
|---|---|
| Clustered | Buildings grouped closely together |
| Dispersed | Farmhouses spread far apart |
| Linear | Houses set out along a road or river |
Cities: problems and planning
- The central business district is the heart of a city’s business; suburbs are residential; factories stand in an industrial area.
- An informal settlement is put up without formal planning; clean water and sanitation are the most important service for a growing settlement.
- Urban decay: an area becomes neglected. Urban renewal: it is repaired.
- Urban sprawl swallows farmland; a green belt around the city limits it.
- People sometimes build on a floodplain because the land is cheap and near work.
The main aim of town planning is to manage growth in an orderly way.
Remember this and test yourself
- Site factors explain why a settlement started in a place: Johannesburg (gold), Durban and Cape Town (harbours).
- Shapes: clustered (buildings close together), dispersed (farmhouses far apart), linear (along a road).
- A city has a central business district, suburbs and an industrial area; a market town is where farmers buy and sell.
- Urban decay is neglect; urban renewal repairs it. Urban sprawl swallows farmland.
- A green belt limits unchecked sprawl; town planning manages growth in an orderly way.

Clustered = a bunch of grapes. Dispersed = stars in the sky. Linear = beads on a string along the road.
