Urban Development and Population Terms
Ever wondered why cities keep growing outward into the countryside? Urban sprawl happens when cities expand beyond their original boundaries, often creating debates about where new housing should go. You'll need to understand the difference between brownfield sites (previously used urban land) and greenfield sites (untouched land) - this comes up loads in exam questions about sustainable development.
Urbanisation drives much of what we see in modern geography, as more people move from rural areas (countryside) to urban areas (cities and towns). This process creates natural increase when birth rates exceed death rates, leading to higher population density in certain areas. Sometimes this rapid growth results in squatter settlements - makeshift housing areas that spring up without proper planning.
The multiplier effect shows how one positive change can trigger a chain reaction of benefits throughout a community. For instance, a new shopping centre doesn't just create retail jobs - it also boosts local transport, cafés, and security services.
Quick Tip: Remember that green belts are specifically designed to prevent urban sprawl by restricting development around cities - this often forces developers to choose between brownfield and greenfield sites.
