Characteristics of Urban Places

An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanisation and are categorised by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilisation with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment.

The world’s urban population in 1950 of just 746 million has increased to 3.9 billion in the decades since. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural areas (3.41 billion) and since then the world has become more urban than rural. This was the first time that the majority of the world’s population lived in a city. In 2014 there were 7.25 billion people living on the planet, of which the global urban population comprised 3.9 billion. The Population Division of the United Nations Department of Economic and Social Affairs at that time predicted the urban population would grow to 6.4 billion by 2050, with 37% of that growth to come from three countries: China, India and Nigeria.

9. Dhaka, Bangladesh (Population: 19,578,000)
10. Osaka, Japan (Population: 19,281,665)

Task 1. Check out the short video below from UNICEF. The graphic depicts countries and territories with 2050 urban populations exceeding 100,000 people. Circles are scaled in proportion to urban population size.  Key is as follows:

Purple – More than 75% urban population
Yellow – 50-75% urban population
Blue – 25-50%% urban population
Green – less than 25% urban population

Press play and watch the growth of these urban areas (note definition). Take screen shots of 1950, 2000 & 2050 and then complete a piece of written commentary about the historical and future growth of urban areas. 

Task 2. Using the World City Populations interactive guide here, take a screen shot of the graphic and comment of the location of urban areas around the world experiencing rapid population growth as well as issues relating to potential future climate change (Unit 2) and population displacement (Unit 1).

Case Study: Paris!

Urban environments like paris are diverse areas that have a multitude of modern days functions such as being the centre of business and commerce as well as home to millions of people. They have important roles to play in providing jobs and transport hubs as well as being major centres for the sports, leisure and tourism industries. Widespread urban renewal and processes of gentrification are changing the faces of the major cities around the world. Paris is a very good example of an urban area that has undergone major change, and will be our case study for today.

Task 3. Watch the video beneath. Screen shot 5 modern day functions of Paris and annotate with key details. What do you think the dominant function of Paris is? What do you think the dominant function of Paris was 100 years ago?

*The FUNCTION of an area is its reason, job  or purpose for being.  In urban areas this relates to the purpose of a land use for residential areas, recreation, industry etc.  The dominant function in different cities varies.

Task 4. Find a suitable definition of gentrification, a defining image and a recent news story about the issues surrounding gentrification in Paris!

Site, Function and Land Use

The site of a settlement is the land upon which it was built. There are a number of different factors that can determine the site of a settlement. These are:

  1. Wet point site
  2. Dry point site 
  3. Defensive site 
  4. Aspect 
  5. Shelter 
  6. Trading point 
  7. Resources 

Task 1. Complete the table on the Google Doc worksheet linked below by describing how these site factors can influence the site for a settlement.

Lesson 2. Site and Situation Worksheet (Google Doc)

Task 2. Study this Google map of Paris and try to identify which siting factors were responsible for the growth of the city. Complete your analysis on the Google Doc worksheet.

Task 3. Use the PDF copy of the map provided to complete an annotation exercise to describe the main land use patterns and functions in Paris. Decide which colour represents each of the following areas and then describe the patterns for these areas:

  1. Agricultural zone
  2. Natural greenery
  3. Urban greenery
  4. Dense residential area (apartments/condos)
  5. Semi-dense residential area (single storey housing)
  6. Suburban residential area
  7. Commercial zone (economic activities)
  8. Manufacturing zones
  9. CBD – Central Business District (city centre)
  10. Derelict housing
  11. Airport

Settlement Hierarchies

The word hierarchy means an order or an importance and can be applied to a variety of settings. Think about Aspengrove and how it works in that setting. Now think of government or a football team and you’ll also see this hierarchy at work too.

Task 1. Using the information below, create ONE MEGA DIAGRAM that incorporates the hierarchy triangle (first visual) with the information about settlement size (second visual) and the key definitions (definitions activity).

Picture
Picture

Definitions Activity: Match the following definitions to the key term and then add them to your MEGA DIAGRAM.

?? an area served by a settlement which can also be called its hinterland.

??  the absolute minimum number of people required to support a service and keep it in business?

?? the maximum distance that customers are prepared to travel to access a good or service. 

?? convenience goods bought on a necessity basis and include items such as bread, milk or rice. 

?? more luxurious or goods that are purchased on an infrequent basis and generally more costly such as tablet devices or cars. 

  • Range
  • Sphere of influence
  • High order goods
  • Low order goods

Spontaneous Settlement Growth… vs. Planned Settlement Growth

Large and successful settlements have developed because of a number of favourable factors that have allowed the settlement to grow, prosper and in turn attract more people to the area. At the start of this unit, we looked at the original siting factors for settlements and how some places will never support more than a handful of houses (hamlet) whereas others have grown into megacities (Tokyo/Yokohama). 

Environments that have traditionally encourage settlement growth are located close to the sea (trade, exploration) and in temperate deciduous areas (annual leaf fall leading to good quality soil and therefore productive agriculture). They may have good links with inland areas too enabling those areas to also develop. If you study the megacities map from the previous lesson, you will see the vast majority of these urban areas are located on the coast or at the very least, on a large river a short distance from the sea. 

London, New York, Marseille, Adelaide, Rio de Janeiro, Beijing, Mumbai – all located on coastal areas and allowed access to inland areas (perhaps with the exception of Australian cities due to the significant climatic challenges faced inland!).

Spontaneous Settlement GrowthVance’s Model

James Vance showed how the development of settlements occurred as a result of colonial mercantile (trade) interaction betweens between the colony and the empire. This laid the foundations for the emergence of most urban settlements that we see today and adds a historical-geographical dimension to the study and emergence of settlements.

Task 1.

Arrange the cards, which show Vance’s Model of the development of settlements, in order. Then write no more than 5-8 words beside each card to explain how the settlement grew over time.

Planned Settlement Growth New Towns

The concept of a planned city is more common than you might think! This is usually as a result of trying to reduce the importance of very large cities. Eg: London, Seoul and Rio de Janeiro. Governments and developers have attempted to build New Towns to deflect growth away from these main cities. You will now investigate the planned development of one of the following ‘New Towns’.

  • Option 1. Milton Keynes – London – United Kingdom
  • Option 2. Don Mills – Toronto – Canada

Task 1. Using the information linked below create a fact sheet that shows the reasons for development of either Milton Keynes or Don Mills, and to what extent it has been a successful development. 

Option 1. Milton Keynes

In the 1960s, the UK Government decided that a further generation of new towns in the South East of England was needed to relieve housing congestion in London. Map to show location is here

Population trend of Borough and Urban Area 1801–2011
Since the 1950s, overspill housing for several London boroughs had been constructed in Bletchley. Further studies in the 1960s identified north Buckinghamshire as a possible site for a large new town, a new city, encompassing the existing towns of Bletchley, Stony Stratford and Wolverton.

The New Town was to be the biggest yet, with a target population of 250,000, in a “designated area” of 88.4 km2. The name “Milton Keynes” was taken from the existing village of Milton Keynes on the site.

​On 23 January 1967, when the formal new town designation order was made, the area to be developed was largely farmland and undeveloped villages.

The site was deliberately located equidistant from London, Birmingham, Leicester, Oxford and Cambridge with the intention that it would be self-sustaining and eventually become a major regional centre in its own right. Planning control was taken from elected local authorities and delegated to the Milton Keynes Development Corporation (MKDC). 

Option 2. Don Mills

Don Mills is a mixed-use neighbourhood in the North York district of Toronto, Ontario, Canada. It was developed to be a self-supporting “new town” and was at the time located outside Toronto proper. In 1998, North York, including the Don Mills community, was amalgamated into Toronto proper. Consisting of residential, commercial and industrial sub-districts, it was planned and developed by private enterprise. Map to show location is here.

In several ways it became the blueprint for postwar suburban development in Toronto and contemporary residential neighbourhoods. It is bounded by York Mills Road to the north, Canadian Pacific Railway to the south, Leslie Street to the west, and Don Valley Parkway to the east. It is part of federal and provincial electoral district Don Valley East, and Toronto electoral ward 16: Don Valley East.

Factors affecting the pattern of urban economic activity…

Starter: Barcelona Hyperlapse

Watch the following video and identify the types of economic activity represented in the film.

Task 1. City Land Use Maps

Working individually or together attempt to analyse the land use maps provided. Focus on the patterns of commercial, industrial and residential patterns. Suggest physical (use Google Maps) and human reasons for the patterns. If completed individually feedback your ideas to the rest of the group.

Task 2. Applying Urban Models

Now study the following urban models and try to decide which model best fits each of the cities in the previous task byt deleting the pictures of the models that don’t apply.

Task 3. Explaining Economic Activities in Urban Models

Use the cut-up resource provided to help describe and explain the spatial distribution and characteristics of economic activity in urban areas.

  1. Place the red cards (zones of economic activity) in the correct place on the urban model diagram.
  2. Place the yellow cards (characteristics) with the correct zone.
  3. Place the blue cards with the correct zone and characteristics to explain.

Task 4. Explaining the Central Business District

Land in an urban area can be broadly split up into commerce (retail), industry and residential. The value of the land is associated with these uses as well as the proximity to the Central Business District (CBD).

​Land prices generally decrease as you move away from the most central area of a city although there may be secondary peaks in suburban areas of new development, close to transport links etc. 

  • Bid-rent Value – The cost of land rental – Bid-rent value decreases with distance from the CBD
  • Sphere of Influence – The total area from which people are willing to travel to a urban function
  • Nodality – The degree of connectedness a location has in relation to transport. communications

Using the video above, complete this note taking sheet focusing on the Bid Rent Theory Model. 

Task 5. Economic Activity on the Rural Urban Fringe (RUF)

The RUF is the transition zone between the city and its suburbs, and the countryside. The RUF contains a mixture of land use. this includes residential areas, recreational facilities such as golf courses and farming.

Study the following diagram and identify:

  1. The reasons why economic activity like out-of-town shopping locates in the RUF.
  2. The advantages of out-of-town shopping for consumers.
  3. What other types of economic activity locate in the RUF for the similar reasons?

Task 2. Using the excellent information from the Barcelona Field Studies Centre below. Either use the printed copy provided and highlight the key elements of incidence of poverty & deprivation (red) and informal activity (blue) on the text. Or make notes in a google doc.

Example 2 – Nairobi, Kenya (LIC)

Task 3. Find out a bit more about Nairobi and take some notes on the key demographics by clicking here

Task 4. Read this excellent article by Matt Burdett and complete the following activities:

  1. Describe the location of Nairobi. [2 marks]
  2. Define ‘poverty’ in the urban context. [2 marks]
  3. Describe the pattern of poverty in Nairobi. [3 marks]
  4. Identify at least two features of urban deprivation in Nairobi and for each, describe its distribution. [2+4 marks]
  5. Outline the health issues that are likely to stem from urban deprivation in Nairobi. [4 marks]
