Challenges of an urbanising world Flashcards
(36 cards)
What are the global trends in developing regions in terms of urban and rural populations?
- have very rapid urbanisation
- urban population increasing
- rural population is decreasing
What are the global trends in developed regions in terms of urban and rural populations?
- slow rate of urbanisation as usually developed countries are already quite urbanised
- 80% people in UK live in cities
Explain why most of the future growth of cities is likely to be in the developing world. (4 marks)
- Cities in developing countries are growing much faster than cities in developed countries.
- In developing countries, the urban population is growing as of natural increase - the birth rate is higher than the death rate
- There is also RUM (Rural to Urban migration)
- Many people are moving to the cities as agricultural practices are becoming more mechanised and there are fewer jobs, so people move to cities for work.
- Drought or other natural disasters may also force a move.
- Generally, urban areas provide people with better living conditions, such as piped water, electricity and healthcare, and higher wages.
The urban population of the world in 2000 was 2.84 billion. by 2005 it had risen to 3.15 billion. What was the % rate of change from 2000 to 2005? Round your answer to the nearest whole number? (1 mark)
11%

What is a megacity?
A city with at least 10 million inhabitants
- Megacities are created where economic development is rapid
What is a world city?
A city with a dominant role in global processes
What is urban primacy?
The most important city in a country, which dominates the rest of the country
What is hinterland?
The region around a city
What were the top 5 megacities in 2015 (out of 35)?
- Tokyo
- Jakarta
- Delhi
- Manila
- Seoul
Which continent is the centre of megacity growth?
Asia
- By 2025, Asia should have at least 28 megacities
What are the growth rates of megacities?
- In 1950 there were only two megacities: New York and Tokyo
- By 1985 there were nine
- Megacities in developing and emerging countries are growing very fast
- E.g. Mumbai’s population doubled in size between 1991 and 2013. Growth rates are fuelled by RUM
Explain two reasons why urban primacy can become a problem for developing and emerging countries. (4 marks)
- The main problem of excessive urban primacy is that all economic growth is concentrated in the city while the city’s hinterland is deprived of growth.
- A second problem is that political power also becomes focused in the city. Decision making that affects the whole country takes place in the primate city and is skewed toward the city’s needs, not the country’s.
In 2015, London had a population of 8.6 million. Calculate the percentage increase required for London to become a megacity. Round your answer up to 1 d.p.
16.3% percentage increase: - difference between 2 values - divide by original value - multiply by 100
What are the key factors to why cities grow or decline?
Economic change and migration
Rural-urban migration
When people change where they live from rural areas to urban areas
International migration
When people move to live in another country
Internal migration
When people move from one part of a country to live somewhere else within that same country
Natural increase
The difference between the number of births and deaths in a year
How do cities grow (or decline)?
2 main ways:
- migration - people move to live in the city, or move away from the city
- natural increase
- these two processes are connected - it is usually young people who migrate to live in cities, and so the birth rate for young people is higher than the death rate for old people
What is the main cause of rapid urbanisation in emerging ans developing countries?
Rural-Urban migration
Why does economic development create a multiplier effect?
- economic growth means people move to the city
- more people = bigger workforce so more industries
- more industries = more jobs
- more people = more customers
- more people = more houses to be built
What are the disadvantages of living in rural areas?
- few opportunities
- poor healthcare
- low pay, difficult work
- low level of education
What are the advantages of living in urban areas?
- many more jobs
- better paid
- better education
- better healthcare
- better housing
- modern lifestyle
- many more opportunities
Explain two reasons why economic changes can cause a city to decline in population. (4 marks)
- Economic problems can mean that industries shut down. If it is no longer easy to get a job in a city, people will move away.
- City governments rely on taxes from businesses and residents to make the city a pleasant, safe place to live and work. If economic problems mean that tax payments go down, the city starts to become run-down, crime rates rise and more people move away.
