Welcome to Urban Futures!

Welcome, Geographers! Have you ever noticed how busy and crowded cities feel compared to the quiet countryside? Well, you aren’t alone. For the first time in human history, more than half of the world's population now lives in towns and cities. This is a huge shift in how humans live on Earth!

In these notes, we are going to explore why this is happening, where it is happening fastest, and what it means for the people living there. Don't worry if some of the terms seem big—we'll break them down step-by-step with simple examples. Let’s dive in!

1. How is the Global Pattern of Urbanisation Changing?

Urbanisation is the increase in the proportion of people living in towns and cities. But this isn't happening at the same speed everywhere.

Growth Rates and Development

The speed of urbanisation depends on how "developed" a country is. We usually group countries into three types:

  • ACs (Advanced Countries): Places like the UK or USA. Most people (about 80%) already live in cities. Because of this, the rate of urban growth is very slow or even stopping.
  • LIDCs (Low-Income Developing Countries): Places like Ethiopia or Nepal. Most people still live in the countryside, but the rate of urban growth is very fast.
  • EDCs (Emerging and Developing Countries): Places like Brazil or India. These are in the middle, seeing steady growth as their economies get stronger.

World Cities and Megacities

As cities grow, they fall into two special categories:

  • Megacities: A city with a population of over 10 million people. In 1950, there were only two (New York and Tokyo). Today, there are over 30! Most new megacities are now appearing in Asia and Africa.
  • World Cities: These aren't just about size; they are about influence. They are hubs for finance, trade, and culture that affect the whole world. Examples include London, New York, and Tokyo.
Quick Review:

LIDCs = Fast urban growth.
ACs = Slow urban growth.
Megacity = 10 million+ people.

2. Rapid Urbanisation in LIDCs: Why is it happening?

In many LIDCs, people are moving to cities at a record-breaking pace. There are two main reasons for this: Rural-Urban Migration and Internal Growth.

A. Rural-Urban Migration (The "Push" and "Pull")

This is when people move from the countryside (rural) to the city (urban). Geographers use a simple trick to remember why people move:

Push Factors: Things that make you want to leave the countryside (bad things).

  • Farming is hard work with very low pay.
  • Natural disasters (like droughts) can ruin crops and lead to famine.
  • Lack of schools, doctors, and clean water.

Pull Factors: Things that attract you to the city (good things).

  • More job opportunities with better pay (factories, services).
  • Better "lifestyle" with access to electricity and entertainment.
  • Better healthcare and education for children.

B. Internal Growth

This isn't about people moving; it's about people being born! Most people who move to cities are young adults. They often have children, which increases the population. Because cities have better hospitals, the death rate falls, but the birth rate stays high. This leads to Natural Increase.

The Formula: \(Natural\ Increase = Birth\ Rate - Death\ Rate\)

Memory Aid:

Think of a magnet. Push factors are like the "North" poles repelling each other (pushing you away). Pull factors are like opposite poles (attracting you to the city centre).

3. The Consequences of Rapid Growth in LIDCs

When a city grows too fast, it can't always keep up. This leads to several challenges:

  • Squatter Settlements (Slums): People arrive and have no place to live, so they build "informal" houses out of scrap materials (like wood or plastic) on land they don't own. These lack clean water, toilets, or electricity.
  • Pollution: Too many cars lead to air pollution, and lack of waste collection leads to rubbish in the streets and water.
  • Underemployment: There aren't enough formal jobs for everyone, so people work in the informal sector (like shining shoes or selling fruit on the street) where they don't pay tax and have no job security.

Did you know? In Mumbai, India, over 1 million people live in a single slum area called Dharavi!

In countries like the UK, cities are changing in different ways. People aren't just rushing into the centre; they are moving around.

Suburbanisation

This is when people move from the city centre to the edges (the suburbs).
Why? People want more space, bigger gardens, and quieter streets, but they still want to be close enough to the city to work there. Improvements in trains and roads make this possible.

Counter-urbanisation

This is when people move out of the city entirely to rural villages.
Why? They want to escape the noise and pollution. Many people now "commute" (travel) long distances to work or work from home using the internet.

Re-urbanisation

This is the trend of people moving back into the city centre.
Why? Old factories and warehouses are being turned into luxury flats (this is called gentrification). Young professionals want to be near their jobs and the nightlife (bars, restaurants, theaters).

Common Mistake to Avoid:

Don't confuse Suburbanisation with Counter-urbanisation!
- Suburbanisation = Moving to the edge of the same city.
- Counter-urbanisation = Moving away to a completely different rural area.

Key Takeaways for Section 5.1

  • Urbanisation is happening fastest in LIDCs because of Rural-Urban Migration (Push/Pull) and Internal Growth.
  • Megacities (10m+) are mostly growing in Asia and Africa.
  • ACs (like the UK) see trends like suburbanisation (moving to the edge) and re-urbanisation (moving back to the middle).
  • Rapid growth in poor countries often leads to slums and informal jobs because the city grows faster than the infrastructure.

Don't worry if this seems tricky at first! Just remember that geography is about people and places. Next time you go into a town or city, look around and ask yourself: "Are people moving in, or are they moving out to the suburbs?" You're now thinking like a geographer!
