3.2.3.1- Urbanisation Flashcards
What is the importance of urbanisation in human affairs?
- it is changing the social structure of society as dominant rural culture is replaced by dominant urban culture, similar to the switch between hunter gatherer lifestyle to farming.
- human nature becomes more competitive and we distance family ties
What are the global patterns in urbanisation since 1945?
- population grew from 0.75 billion to 3.9 billion by 2014
- 5x more people living in urban areas than rural
- urbanisation occurred at a rate of 2.5%
- Africa and Asia are urbanising the fastest
Advantages of megacities
- POLITICAL: more liberal and carry global political power due to size of populations
- ECONOMY: UN estimates megacities generate 2-3 x more GDP than other cities
- ENVIRONMENT: better for environment in terms of transport, electricity water and sanitation as population is all in 1 place
- SOCIAL: better access to services like HC and ED
- EMPLOYMENT: population have more access to diversified employment markets. informal economy provides work for poorest or those without official status.
- TECHNOLOGICAL: megacities are often centres of innovation where solutions for global problems are trailled.
Disadvantages of megacities
- TRANSPORT: can be bad if not managed leading to congestion and pollution
- POVERTY: as its hard to provide jobs, housing and infrastructure
- ENVIRONMENT: as more dumps to deal with waste EG. Mumbai produces 6,500 tonnes a day in a creek near a residential. climate change is also affected and expansion removed biodiversity EG urban land will have expanded 3.3 million km2 by 2030
- People pushed to MARGINAL LAND facing flooding and disease
- Slum dwellers face an increased CRIME levels because of poor migrants
- CONFLICT and riots due to bad governance EG Data
- Not enough resources or services
How many people are in a millionaire city, megacity and megacity?
1 million
10 million
20 million
How has the growth of megacities changed?
In 1960 the only 2 megacities were NY and Tokyo
It took 150 years for London to grow to 7 million, but only took 50 years for Mexico City to grow to 15 million, so they are growing more rapidly
Asia has the most megacities, due to its high population. there are 9 megacities in china.
Mostly in LIC/NEE now
Examples of different types of megacities:
Immature megacities: rapid growth and services can’t keep up EG. Nigeria
Consolidating megacities: begin to provide basic services-self help schemes EG. Mumbai
Maturing megacities: more developed formal economy and service industries EG. Sao Paulo, Brazil
Established megacities: effective governance, sustainability projects EG. London
What are the features of world cities?
- recognised worldwide
- unchallenged seats of prestige, power, status and influence
- comand and control centres of global economy EG. New York stock exchange controls economy of developed world
- major transport and communication hubs to deliver advanced services globally EG. trade in Tokyo
- great education
- political power and participate in global events like G8 summits EG. NY United Nations
- cultural dimension through ethnic diversity, foreign embassies, sport and art EG. broadway NY and now in developing world too like like Nollywood in Nigeria. Don’t have to be big but still have influence over world eg. Milan centre of world fashion industry in Italy
Location of World cities
- N america, Europe and Asia EG London Tokyo and NY
- developing world
- near water for international trade
Ranking of world cities
Alpha- very integrated EG. London
Alpha* cities- integrated cities that complement Alpha EG. Tokyo
Alpha- link major economic regions into the world economy EG. Chicago
Beta- link their own region into the world economy EG. Copenhagen
Gamma- link smaller regions into the world economy EG. Bristol
Examples of magacities
Shanghai has 7,000 billionaires, 100,000 new homes built ever month for people in slums
Dhaka has 12 million people, 0.5 million migrants every year, 4 million people in slums but very vibrant
Push factors for suburbanisation
overcrowding pollution bad housing congestion lower QOL
Pull factors for suburbanisation
more green space for better QOL better for families eg. schools lower levels of crime peaceful jobs started to open up in suburbs although expensive land, cheaper houses
History of suburbanisation
First happened in USA during WW1 where many African Americans moved north to south looking for jobs
As a result many white families moved out of the cities-white flight
This was also seen in the UK in 1950-60’s as there was a shortage of workforce after the world war so government encouraged people from British empire to move to the UK, where they searched for jobs in city and white flight occurred
2019 onwards far more people work from home and some jobs have moved to the suburbs (decentralisation)
Negative impacts of suburbanisation
house prices in suburbs increases
decline of CBD and inner city as edge cities have occurred (decentralisation)- needs better transport links
huge increase in car ownership leading to pollution and congestion
urban sprawl and pressure on greenbelts
loss of community in suburbs
Advantages of suburbanisation
- increasing employment opportunities in offices and shops
- derelict land can be cleared in inner city improving environment
- local tax base increases so councils can afford new services and facilities
Advantages of counter urbanisation
cheap housing in inner city
less cars so less population
areas can be redeveloped and put to better use
easier access to health and education
Disadvantages of counter urbanisation
less community shops may close in inner city taxes decrease dormitory in day as people commute (talk about rural areas mainly)
what is the difference between suburbanisation and counter urbanisation?
suburbanisation is the movement of people from inner parts of a city to the city suburbs/rural urban fringe, whearas counter urbanisation is the movement of people out of large cities to rural areas beyond the greenbelt
Causes of counter urbanisation
high population densities in the cities increased amounts of people who can commute increased access to online shopping safer less congestion collapse of inner city industries people can work from home increased affluence whereas developing countries are still going through urbanisation
