Global Urbanisation Trend • London was the first city to have several million inhabitants,

reaching this size in the second half of the 19th century, reflecting its status as the economic and political centre of the British Empire. By 2005, there were 50 cities with more than 5 million people, including 20 'mega-cities' with more than 10 million people.

• The world's population is at a historic turning point. In 2008, half the world's population lived in urban areas. The urban population of 3.3 billion people in 2008 will be larger than the entire global population in 1967, 40 years earlier.

• In 2007, developing countries had some 2.4 billion urban dwellers compared with 900 million in industrialized countries. Half of all urban growth in developing countries was attributed to in-migration and other half on high birth-rate.

• Prior to 1950 the majority of urbanisation occurred in MEDCs (more economically developed countries). Rapid urbanisation took place during the period of industrialisation that took place in Europe and North America in the nineteenth and early twentieth centuries. Many people moved from rural to urban areas to get jobs in the rapidly expanding industries in many large towns and cities. Since 1950 urbanisation has slowed in most MEDCs, and now some of the biggest cities are losing population as people move away from the city to rural environments. This is known as counter-urbanisation. You can read more about this process on the next slide.

• Since 1950 the most rapid growth in urbanisation has occurred in LEDCs (Less Economically Developed Countries) in South America, Africa and Asia. Between 1950 and 1990 the urban population living in LEDCs doubled. In developed countries the increase was less than half.

• The three main causes of urbanisation in LEDCs since 1950 are: • 1. Rural to urban migration is happening on a massive scale due to population pressure and

lack of resources in rural areas. This are 'push' factors. • 2. People living in rural areas are 'pulled' to the city. Often they believe that the standard of

living in urban areas will be much better than in rural areas. They are usually wrong. People also hope for well paid jobs, the greater opportunities to find casual or 'informal' work, better health care and education.

• 3. Natural increase caused by a decrease in death rates while birth rates remain high. • The UN predicts that by 2030 60% of the world's population will live in urban environments.

Page 11: Urban change powerpoint all slides

Counter urbanisation • Counter-urbanisation is the movement of people out of cities, to the surrounding

areas. Since 1950 this process has been occurring in MEDCs (More Economically Developed Countries). There are four main reasons for counter-urbanisation:

• 1. The increase in car ownership over the last 40 years means people are more mobile. This has led to an increase in commuting. Also, the growth in information technology (E-mail, faxes and video conferencing) means more people can work from home.

• 2. Urban areas are becoming increasing unpleasant place to live. This is the result of pollution, crime and traffic congestion.

• 3. More people tend to move when they retire. • 4. New business parks on the edge of cities (on Greenfield sites) mean people no

longer have to travel to the city centre. People now prefer to live on the outskirts of the city to be near where they work.

Urban Growth in the UK

Page 18: Urban change powerpoint all slides

Urban Growth in the UK • First towns emerged in the “middle ages” (1154 – 1485)• Slow and steady rate of urbanisation until 1800• Rapid urbanisation during the Industrial Revolution• Rapid growth was between 1800 and 1960• 1960 90% of UK lived in urban areas• Some areas merged together to form conurbations (e.g. Greater-

Manchester has ‘enveloped’ surrounding towns and cities)• This trend has been reversed slightly in recent years (counter-

urbanisation, suburbanisation)• 95% of land in Scotland is rural. 95% of Scotland’s population live

in the other 5%.

Page 19: Urban change powerpoint all slides

Reasons for rapid urbanisation in the 19th century

• Industrial revolution • People moved to towns and cities in search for

work in the heavy industry (iron works, ship building) labour intensive.

• Raw material and industrial products were imported and exported ports grew rapidly labour intensive.

Page 20: Urban change powerpoint all slides

Rapid urbanisation up to 1960

Because… • Industries were still growing and still

employing large number of people. But also because….• Tourist resorts Blackpool• Retirement centres Bournemouth, Largs,• Planned new towns East Kilbride.

Page 21: Urban change powerpoint all slides

Since 1960...

• Basically no major increase in rate of urbanisation.

• In recent years people have started to move out from urbanised areas “Counter-urbanisation”

Physical Map of UK to show the relief of the country.

•Make sure you know where the hilly and mountainous areas are:

•Mountainous area = no large urban settlement.

•Also, make sure you know where else we have fewer or no large urban settlement due to its location and the relief of the land.

Page 31: Urban change powerpoint all slides

•Many of the UK’s largest cities are situated near or next to the coast, for example: Glasgow, Edinburgh, London, Liverpool, Sheffield, Leeds, Manchester and Newcastle. These settlements are on the coast because of trade (port), mild climate in the south coast, sheltered bays and estuaries which was well suited to be used as sea-side resorts and retirement centres (Bournemouth and Brighton).

•Inland cities such as Birmingham (route centre) are found in the north of the attractiveness of their site (flat land, water, soil natural resources, etc..) and their accessible location.

•Fewer large settlements are found in the north of Scotland, north Wales and parts of north-west England because of the mountainous nature of the land. The north of Scotland, including the Western Isles, Orkney and Shetland, are also quite isolated with long and expensive transport links to the cities.

Large cities are also absent from parts of south-west England because of the remoteness of the region and its poor accessibility.

Urban change in inner city Glasgow Gorbals and Clyde Waterfront

Page 48: Urban change powerpoint all slides

Background Info• During the mid to late 19th century Glasgow grew into a major industrial

city and trading port. Mass shipbuilding along the Clyde began an industrial boom based around coal, iron and steel.

• The population outstripped that of Edinburgh, large public and commercial buildings were constructed based on classical and Italianate models and the locals often referred to Glasgow as 'the second city of Empire'.

• During the 1860s and 70s, the building of tenements increased by around 600%, with more than 20,000 tenement flats built between 1872 and 1876 to accommodate the city's growing workforce.

• By the mid 1940s, Glasgow was famed for having some of the worst housing conditions in the British Isles. To address this and other problems, two reports were published in 1945 (written by Robert Bruce) outlining plans to redevelop Glasgow into a healthier, more modern city.

Page 49: Urban change powerpoint all slides

Background • Glasgow's rapid growth as an industrial city in the 19th and 20th

centuries created a legacy of poor, cramped housing, with frequent bouts of high unemployment.

• The social problems were probably at their worst in the Gorbals area, just south of the river Clyde. The Gorbals has long had a reputation as a gritty and rough area.

• After the Second World War, attempts were made to re-house those in sub-standard tenement blocks by moving them to new estates on the edge of the city. In the Gorbals, the old buildings were demolished and new high-rise flats arose in their place .The old community spirit of the area was thus largely destroyed.

• In recent years, some of the high-rise blocks have been demolished and rows of modern low-rise flats are being built. Hopefully, this second attempt at regenerating the Gorbals will be more successful.

Housing changes

• During the industrial revolution- low cost housing were built in a grid-iron pattern, often with small narrow streets. By the 1950s these old tenements were suffering from decay. – Over crowding, – Bad hygiene from lack of basic amenities– Pollution from factories – Old and run-down, structurally unsound buildings

Page 57: Urban change powerpoint all slides

1960s• Glasgow Corporation's redevelopment program

targeting its massive housing problems was ambitious. It earmarked 29 inner city areas across the city as Comprehensive Development Areas (CDAs). Hutchesontown, with part of the Gorbals, was to be the first.

• At the same time some people were moved out of Gorbals to out of city estates like Castlemilk and some to new towns like East Kilbride and Cumbernauld.

Page 58: Urban change powerpoint all slides
Page 59: Urban change powerpoint all slides
Page 60: Urban change powerpoint all slides

1960s

• Old tenements were demolished and (first generation) of high-rise flats were built.

• During the 60s there was a huge rise in the standard of living. Around 20% of Scots moved into a new house and for many it was the first time they had a toilet inside!

Negati ve/eff ects

Not great for…Young mother, small children, Old people and people with mobility problems.

Despite the “open areas” there were few safe places to play

Gorbals lost the sense of community

The building suffered from damp

Many social problems due to high unemployment rate

Page 67: Urban change powerpoint all slides

Hangover from 1960s…• Comprehensive redevelopment (New high-rise

flats) created more problems for Glasgow..– Social problems crime and deprivation– 1960s decline of heavy industry higher

unemployment rate– High-rise cheaply and poorly built, lots of communal

space but little personal space lack of ownership poor state of care.

– New towns (East Kilbride) very expensive to build.– Outer-city estates (Castlemilk) poor public transport

links, far from jobs and services.

(second attempt) Your Gorbals and Clyde water front field-trip knowledge will be useful in this section

Page 70: Urban change powerpoint all slides

Housing.

• Housing renovation of tenements. • Consultation with the residents housing

association. (GHA 2003)• Building more expensive (quality) houses/flats

for private ownership e.g. New houses in Gorbals

Page 71: Urban change powerpoint all slides

Jobs

• Brown field sites modern industrial estates grants and other incentives from the government (Industry Unit) – For example: Dixon’s Blazes (Ironworks)

• Job training for local people• The “new deal” on benefits job seekers

allowance.

Page 72: Urban change powerpoint all slides

Dixon’s Blazes

Page 73: Urban change powerpoint all slides

Services

• More health centres e.g.• More community centres e.g.• Shopping Centres e.g.

Environment

• Landscaping • Reclamation of old industrial sites (brown field

sites) • Fewer heavy industry to pollute the air and

Page 78: Urban change powerpoint all slides

Problems before 1970s• Docks (e.g. Princess Docks), shipyards,

warehouses began to close because: – River Clyde was too narrow for the modern ships– Competition from overseas

• Clyde water front was derelict wasteland. • Tenements were polluted and lacked

amenities.

Page 79: Urban change powerpoint all slides

Solution• Derelict dockland was reclaimed (brown-field sites)• leisure and tourist facilities built Science Centre, SECC,

Springfield Quay entertainment complex etc.. • New offices built BBC, STV, Daily Mail, BT… • New expensive waterfront flats built Lancefield Quay and

Glasgow Harbour Development.• New bridges build to improve transport connection to the city.

The Millennium bridge, Squinty and Squiggly bridge.

Page 80: Urban change powerpoint all slides

Effectivness Positive Not so effective…

Brought many new jobs News jobs all require “qualifications” most of the jobs are too “highly skilled” for the original working population of the area.

Improved the environment quality of the area

Some of the original residence of Clyde waterfront can’t afford to buy the new expensive flats

Helped Glasgow become a major tourist destination. “City-break” destination

Most people who can’t afford the new accommodations had to move to the peripheral estates.

Urban Problems in Glasgow

•Traffic congestion •Decentralisation of shop and

entertainments•Lack of open space Urban Sprawl

Page 83: Urban change powerpoint all slides

CBD Traffic Congestion

Page 84: Urban change powerpoint all slides

What causes an increase in traffic congestion?

1. Increase in car ownership2. Increase in commuter traffic from rural-urban fringe areas. (rush hour) 3. High day-time population work, shopping, entertainment and other

services. 4. Poor quality of road within inner city area. 5. Old narrow road and lanes in the CBD difficult to widen them due to

high building density (not enough space) and listed buildings. 6. Grid iron pattern too many road intersection more traffic lights 7. CBD is central point where many routes meet. 8. Inadequate public transport system. 9. Not enough investment in transport infrastructure. 10. Buses, lorries, pedestrians and street parking all taking up valuable

space and slowing down traffic.

Page 85: Urban change powerpoint all slides

Effects 1. Shops and services (offices) move out

from CBD empty premises and less jobs. 2. Air and noise pollution 3. Accidents and fatalities 4. More money on road maintenance road

work slows down traffic! 5. Waste of time (money) and fuel

Page 86: Urban change powerpoint all slides

Solutions EffectivenessOne-way street (grid iron)

Page 87: Urban change powerpoint all slides
Page 88: Urban change powerpoint all slides
Page 89: Urban change powerpoint all slides

Decentralisation of shop and entertainment

Page 90: Urban change powerpoint all slides

Decentralisation of shop and entertainment

Cause? • Declining population in city and inner city.

(Urban-rural migration/depopulation/urban-sprawl)

• Increase ownership of cars people are mobile people will travel longer distance to obtain cheaper products and services.

• CBD land price is very expensive.

Page 91: Urban change powerpoint all slides

Out of town shopping centre

Causes: • Cheaper land more space for car parking (free)• Good transport system (motorway) • Out of town usually has less traffic • More open space• Indoor shopping space • Attractive environment

For example: Braehead , Silverburn and Glasgow Fort,

Page 92: Urban change powerpoint all slides

Effects

• Less traffic congestion in CBD • In theory should lead to lower land price in

CBD due to less demand• Increased congestion near the new shopping

centre• Less variety of shops in CBD less attractive

place to shop? • Out of town shopping centre isn’t accessible

to everyone people who can’t drive.

Urban Sprawl

Page 98: Urban change powerpoint all slides
Page 99: Urban change powerpoint all slides

With reference to a named city in the EMDC:a) What land uses are found at the fringe of the

city?b) What are the causes of Urban Sprawl? c) What problems and conflicts are likely to

occur? d) What strategies can we use to tackle the

conflicts and urban sprawl issues?e) How effective has this been?

15~20 marks

Page 100: Urban change powerpoint all slides

Land-use

Page 101: Urban change powerpoint all slides

Causes (reasons why…) • Increased urban population pressure for outward residential expansion• Land price is much higher in inner-city and in CDB compared to the suburbs

(remember your bid-rent theory from “Urban” unit) • Growth of villages in the commuter belt these areas are very popular area to live. • Suburbs and beyond are popular place to live because was lower crime rate, better

air quality, space for garden, parking space. (Environmental quality)• Good road links and other transport infrastructure• Need for other development airport expansion• Demand for services more land • Recreational demands for land. (golf)• Location is also popular with new (modern and light) industry, office and science

complex. • Pressure for retail and commercial expansion out of town shopping centre• Movement of jobs from inner-city/CBD suburbs. (e.g. Modern Office parks,

science parks, modern light industrial complex) • Changes in the CBD need for out of town facilities.• Pressure to find more space for urban waste (landfill sites, sewage works…)

Page 102: Urban change powerpoint all slides

Problems and conflicts (effects)• Loss of farmland (often fertile), loss of existing woodlands and

school playing fields. Also loss of wildlife habitats. • Conflicting demands for other uses such as recreation,

transport, retail, industry, airports… usually any such development is unwanted by existing users of the land (not in my back yard!)

• Loss of community feeling in existing villages• Loss of ‘quality of rural life’ • As the city grows at the edges, then the city centre loses little of

it’s character, shops, services and other facilities…• Pollution increase at the Rural-Urban fringe.

Page 103: Urban change powerpoint all slides

Strategies (Solutions)

• Planning control/restrictions/zoning creation of green belts. Creation of overall plan for the city.

• Encouraging development in other areas through the use of grants and loans. (enterprise zones, new-towns, brown-field sites).

• Encouraging improvements within the CBD and the ‘inner-city’ (Gorbals)

• Counter-urbanisation strategies to encourage developments within existing city boundaries.

Page 104: Urban change powerpoint all slides

Effectiveness• The main problems is that there is a demand for new

developments (especially housing) and this is difficult to stop. • People generally want to improve their ‘quality of life’ and the

strategies mentioned can really only work with the support of local and national government and with the support from the local people.

• The creation of restrictive zones (green belt) has reduced the rate of urban sprawl but not completely stopped it.

• Often plans are too ambitious or expensive. • Often the plan ignores the social and human needs of the

people. Experience shows that the plans are too rigid, under-resourced and based on incomplete analyses of need.

Page 112: Urban change powerpoint all slides

Site of Karachi• Original site of Karachi was in River Lyari

estuary where it is sheltered and very close to the Arabian sea.

• Easy to defend (island and sand spits) • Fresh water from the River Lyari.• Woodland near by building and fuel. • Flat farmland near river valley fertile land.

Page 113: Urban change powerpoint all slides

Situation, Growth and Function of Karachi

Early history- until 1840 (slow rate of urbanisation)

• Sheltered original site perfect spot for harbour fishing port

• The original site had a protective wall built for extra protection.

Page 114: Urban change powerpoint all slides

1840-1947 (colonial period) quite rapid urbanisation

Page 115: Urban change powerpoint all slides

• The British empire made Karachi their regional capital which created many jobs.

• British built the transport infrastructure railways, bridges, roads became a route centre.

• British improved small and old fishing port commercial port (export/import British goods)

Page 116: Urban change powerpoint all slides

1947 onwards Very rapid growth

• 1947 year of independence from the British. • Pakistan as a country was born Karachi was

the new capital more jobs. • Became a major industrial centre due to?• Became a major immigration centre due to?

Page 117: Urban change powerpoint all slides

Reasons for rapid growth Push factor

1. Small, uneconomic farms2. Unreliable rainfall3. Farmland degrading4. Lack of high schools and

hospitals

Pull Factor

1. Factory and office jobs in towns2. Nearly all port jobs are in towns3. Secondary schools, hospitals

etc.4. Shopping malls, entertainment

etc. ‘Bright Lights’5. Better housing – electricity and

piped water6. New capital city - Islamabad

QB(iii) Effective? Government, NGO

Page 121: Urban change powerpoint all slides

Social (housing) Economic Environmental

Over crowded condition in the shanty-town because Karachi authorities are not building enough affordable houses. growth of illegal settlement (shanty towns)

Not enough employment. (9-5 jobs). People in shanty towns usually work very long hours for little pay. So high unemployment and under-employment rate.

Pollution from lack of proper sewage system . Pollution also from lack of proper rubbish collection system.

Shanty town houses are made from poor materials structurally unsound and un-slightly.

Not enough factory jobs MNCs bring their own staff and expect good . Mechanisation of factories less manual jobs available.

Traffic congestion like with any major cities Karachi suffers from Traffic congestion. Made worse by narrow streets and few traffic lights. air and noise pollution.

No piped water, proper sewage system or electricity. No rubbish collection

Many government jobs have moved to the new capital.

Air pollution from the factories due to lax environmental laws.

No proper address High unemployment

Pakistani government and local authorities do not have enough money to spend to improve the city.

Polluted water from factories and sewage wide spread infectious diseases.

High level of diseases from poor sanitation, pollution and poor living standards

Most people who live and work in shanty town do not pay tax (black market/informal sector)

High crime-rate Karachi attracts many MNCs but some do not follow ethical code of conduct workers are under paid and miss treated.
