Settlement geography is the study of where people live and the reasons why they live where they do. If you know and understand the key concepts on the next page, you will be able to answer most of the questions in the Settlement section of the final exam. Make mobile notes (instructions are on page x in the introduction) and use them to learn these key concepts.

In this chapter we learn that settlements are classified according to function, or size and complexity. 3.1.1 Function
Rural settlements are mainly unifunctional (they have one main function) with only primary economic activities occurring, e.g. farming or forestry.
Urban settlements are multifunctional (they have many functions), i.e. they have both secondary activities (factories/manufacturing) and tertiary activities (services).
3.1.2 Size and complexity
Settlements are classified from the smallest to the largest.
A farmstead, hamlet and village are rural settlements.
A town, city, metropolis, conurbation and megalopolis are urban settlements.
Study Figure 3.1.2 below to understand the differences in size and complexity of rural and urban settlements.
Rural
Farmstead A single farm and outbuildings
Hamlet A loose grouping of a few farmsteads
Village A denser grouping of many farmsteads
Urban
Town A densely populated urban area, e.g. Harrismith or Beaufort West
City A large town where many people live and work, e.g. East London, Bloemfontein
Metropolis A main city in a region which is surrounded by dependent towns, e.g. Cape Town, Durban, Port Elizabeth
Conurbation A large urban area formed by the growth and coalescence of a number of cities and towns, e.g. Witwatersrand
Megalopolis A gigantic urban complex formed when a number of conurbations join, e.g. Boston, New York and Washington (Bonywash)
Figure 3.1.2: Size and complexity of settlements It is important to be able to classify settlements according to their function, size and complexity, and pattern.

Rural settlements are the smallest settlements which are unifunctional. They are farmsteads, hamlets or villages, where primary activities (farming, fishing, forestry or mining) take place. Figure 3.2.A illustrates a rural settlement.
Land use in rural settlements The largest land use in South Africa is agriculture. Approximately 12, 1% of the land is used for both commercial and subsistence cultivation of crops. Although rural communities focus on primary economic activities (farming and forestry), there are a number of different ways in which the land in these settlements can be used. Subsistence farming involves using the land to grow crops and breed animals that are a source of food for the family living on the farm. The aim is not to sell the goods, but to consume them. Commercial farming is practised where the land is used to grow crops or breed animals that are then sold as food sources to other markets. The main aim of this rural land use is to generate income for the farmers. Commercial farming can be either intensive or extensive. Commercial farming can be divided into:
Stock farming: Animals, for example, cows, chicken, sheep, pigs.
Crop farming: Cultivation of land, for example, maize, wheat, fruit, vegetables.
Mixed farming: A combination of stock and crop farming.
You need to know how to identify stock and crop farming on a map.
Rural settlement patterns A rural settlement pattern refers to whether the farmsteads are grouped together or not. There are two rural settlement patterns:
Nucleated pattern: Farmsteads are arranged close to one another. Figure 3.2.B (below left) shows a nucleated pattern. These buildings are rural, so they cannot be classified as being larger than a hamlet or village.
Dispersed pattern: Farmsteads are arranged far apart from one another. Figure 3.2.C (below right) shows a dispersed pattern. This can only be an isolated farmstead – this is one farm house, stables or sheds or kraals, and surrounding fields.
Try to imagine yourself living in these different settlement patterns to help you remember the advantages and disadvantages. In an exam you may be asked to identify the pattern of settlement (nucleated or dispersed). Learn Figures 3.2B and 3.2C below to enable you to answer this question. In the exam, you may be asked what the advantages or disadvantages are of living in a nucleated or dispersed settlement. Study table 3.1 (right) to help you answer this question.
Nucleated rural settlement
Advantages
Disadvantages
More interaction with people
Safer as there are more people
Can share ideas on how to solve a problem
Can share the cost of tools and machinery
Not enough privacy
There may be arguments as you have to agree on how to solve a problem
Have to share the profits
Cannot use tools or machinery when you want to
Dispersed rural settlement
Advantages
Disadvantages
More privacy
Can make your own decisions
All the profit is your own
Better use of machinery and tools
Not enough interaction with people
Not as safe as it is far from other people
Have to pay for all costs by yourself
Difficult to share ideas when you have a problem
Table 3.1: Advantages and disadvantages of living in a dispersed or nucleated rural settlement When you learn these advantages and disadvantages remember that:
If it is an advantage for nucleated it will be a disadvantage for dispersed.
If it is a disadvantage for dispersed it will be an advantage for nucleated.
3.2.1 Reasons for the location of rural settlements Where a settlement occurs is referred to as its location. We will discuss the location of settlements under the headings site and situation.
The site of a rural settlement refers to the exact piece of ground the settlement is found on.
The situation of a settlement refers to the settlement in relation to its surrounding environment.
Figure 3.2.1A below illustrates the relationship between the site and the situation of a settlement.
Site of a rural settlement When choosing a site for rural settlements, the following factors are considered:
Availability of water
Arable (fertile) land
Pastoral (grazing) land
Building materials
Fuel such as wood from a forest
Situation of a settlement When choosing a situation for rural settlements the following factors are considered:
Above the flood line away from a river
On the north-facing slope for warmer temperatures
In the thermal belt for warmer night time temperatures
Next to a road for accessibility
These last two factors are not as relevant today as they were in the past. In an exam you may be asked to identify factors that affected the choice of the site of a particular settlement in a diagram. In this type of question if a key is given, study it carefully to help you answer the question.
Activity 3.2 Study the two rural settlement diagrams in Figures 3.2.1B and 3.2.1C and complete the table.

[16] 3.2.2 Rural-urban migration As countries develop and urban areas expand, more and more people move from the rural areas to cities and towns. This movement of people from a rural area to an urban area is called rural-urban migration. In this section we look at the factors that cause people to leave the rural areas (push factors) and move to the urban areas (pull factors). We will also look at what governments do to keep people in the rural areas.
Push and pull factors causing people to leave the rural areas Table 3.2 below summarises the factors that make people want to leave the rural areas and move to cities. Make sure you understand the difference between push and pull factors.
Push factors
Remember, these make you want to leave rural areas. They push you away.
Pull factors
Remember, these make you want to move to urban areas. They pull you in.
Natural disasters, such as drought or floods, have a greater impact in rural areas.
Natural disasters have a smaller impact; government provides more help to urban areas during droughts and floods.
Lack of facilities in rural areas, e.g. fewer schools, colleges or universities, and fewer hospitals or clinics in rural areas
Better and more access to education and medical facilities in urban areas
Lack of services in rural areas, e.g. water, electricity, transport
Better access to services in urban areas, e.g. water, electricity, transport
Lack of employment in rural areas – few jobs are available and there is little variety in the types of jobs available
More jobs and more types of jobs available in urban areas
Lack of housing in rural areas
More housing and better housing available in urban areas
Lack of recreational facilities, entertainment and social interaction in rural areas
More recreational facilities, entertainment and social interaction in urban areas
Poverty in rural areas, which limits people's chances of improving their standard of living.
Better standard of living possible in urban areas
Table 3.2: Push and pull factors
Strategies for getting people to stay in rural areas Rural to urban migration causes many problems in rural and urban areas. Because of this, the government has various solutions or strategies (plans) to keep people in rural areas and to attract people back to rural areas. Agenda 21 is a broad strategy to develop rural areas. Some of the basic ideas are included in the list below:
Before you can implement a solution, it is important to speak to the local people and get their ideas on how to improve the area.
Solutions should look to use the skills and talents of the local people.
Basic needs (food, shelter, clothing and clean running water) must be satisfied before other development can happen.
Improve services (like electricity and roads) and facilities (like hospitals and schools) to encourage people to stay in the area.
When providing for these basic needs, such as building roads or clinics, use local labour and train people so they can use their new skill or trade to earn a living in the area.
Improve food security by educating farmers in the use of better farming methods, tools and seeds.
Attract secondary activities, like factories, to rural areas. Encourage these industries to use local raw materials and skills to ensure rural people are employed.
Rural depopulation does not only affect rural areas but also small towns. Many people are leaving small towns to move to the big cities. Below are some basic ideas to consider when improving small towns:
Improve roads to and from the small town.
Upgrade facilities in the small town.
Town councils must find ways to advertise their town to attract tourists or people to come and live there, for example:
Build old age homes and offer services specifically for older people. This would attract older people to retire to the small town.
Develop a holiday resort, or attract people for weekend getaways to the small town.
Urban settlements are towns or cities where secondary and tertiary activities take place. More and more people are living in urban areas so towns are growing larger and more complex all the time. Figure 3.3A below shows an urban settlement.
3.3.1 Reasons for the location of urban settlements Where a settlement is found or occurs is referred to as its location. Site of an urban settlement When choosing a site for urban settlements, the following factors are considered:
Availability of water: This is no longer as relevant, since water can be piped over long distances.
Soil: People prefer to build on soil which allows water to drain through it. It is difficult to build on clay because water collects on top of this type of soil.
Rock structure: Sites which are far from sinkholes, fault lines and volcanoes are better to build on.
Relief: Sites with gentle gradients are preferred, as building costs are cheaper.
Transport and trade: Development often occurs at a river crossing.
Human factors: Sites with historical, cultural or social value attract people to live in the area.
In an exam you may be asked to identify factors that affected the choice of a particular settlement in a diagram. In this type of question, if a key is given look at it carefully to help you answer the question. Learn the information (left) to help you answer this question.
3.3.2 Types of urban settlements Urban areas are classified according to their function (the main reason why they are there). There are three main types of urban areas:
Central places
Trade and transport towns or cities
Specialised town or cities
Table 3.3 summarises the three types of urban areas.
1. Central places
Small towns supplying urban goods and services to surrounding rural areas
Low order good/service • Need often (bread, milk, doctor) • Smaller threshold population • Several shops/services
High order good/service • Don't need or need less often (e.g. TV, health spa) • Larger threshold population • Few shops/services
2. Trade/transport towns or cities
Develop where transport routes meet
Break of bulk Transport changes, e.g. from sea to land
Example: Durban
Junction Intersection of two main transport routes
Example: De Aar (Touws River)
Gap Point of access at physical barrier (e.g. mountain pass)
Example: De Doorns (Hex River Pass)
3. Specialised towns or cities
Develop because of one main function in the area
Mining
Example: Welkom
Education
Example: Grahamstown
Industrial
Example: Secunda
Resort
Example: Margate
Commuter/dormitory
Example: Soweto
Table 3.3: The three types of urban areas
Use the word CRIME to help you remember the different types of specialised towns: C Commuter R Resort I Industrial M Mining E Education
Make up your own mnemonics to remember the facts about these three types of urban areas (see page xi in the introduction to learn more about mnemonics).
Central places Central places are small towns that supply urban services to the surrounding rural area. They have shops that sell basic goods or provide basic services to people who live and work on the farms in the area. Goods or services may be classified as low or high order. Study Table 3.4 below to learn the differences between low and high order goods or services.
Low order goods/services
High order goods/services
Definition
A function or good you need or buy often
A function or good you buy less often or do not need on a regular basis
Examples
Low order goods: bread, milk, petrol Low order services: doctors, mechanics
High order goods: television, designer shoes High order services: specialist doctors, health spas
Threshold population
Smaller number of people
Larger number of people
Number of these shops or services
Many – people want to buy low order goods and services on a regular basis
Few – people do not need high order goods and services very often
Table 3.4: Low and high order goods or services
Threshold population: The number of people a function must serve in order to be profitable, or the number of people needed to support a function or town. Threshold population refers to how many customers a shop or service must have in order to be profitable.
Range: The distance a person will travel to obtain a particular good or service. Range refers to how far someone will travel to buy a particular product or access a particular service.
Sphere of influence or service area: The area served by a business selling a particular good or service. This is the area where people live who buy goods from a particular shop or use a particular service.
Make sure you know these three definitions which relate to central places. They are easy marks!
Activity 3.3
Expand the blank diagram in Figure 3.3.2A below and use the following terms to add a key to the diagram:
Threshold population (1 × 2 = 2)
Range (1 × 2 = 2)
Sphere of influence (1 × 2 = 2)
Write definitions to show your understanding of the terms in a), b) and c). (3 × 2 = 6) [12]
Apply what you have learnt about central places by completing activity 3.3.
Answers to activity 3.3
The minimum number of people needed to maintain a settlement or function (2)
The maximum distance people are prepared to travel to a settlement or a function (2)
The maximum area served by a settlement or function (2) [12]
Trade and transport towns or cities These are towns or cities which develop at a point where transport routes meet. Easy access to trade and transport in the area is the reason why people settle there. There are three types of trade and transport cities:
Break-of-bulk towns or cities: They develop at a point where the type of transport changes. This is most often at a harbour where the transport changes from sea to land.
Junction towns or cities: They develop at an intersection of two major transport routes, for example a railway junction.
Gap towns or cities: They develop at a point of access through or over a physical barrier, for example at a mountain pass.
Specialised towns or cities These are towns or cities which have developed because of one main or dominant function occurring in the area. If the function were to stop then the city would be at risk of becoming a ghost town (a deserted town). Examples of specialised towns or cities are:
Mining towns or cities, e.g. Welkom
Education towns or cities, e.g. Grahamstown
Industrial towns or cities, e.g. Secunda, Sasolburg
Resort towns or cities, e.g. Margate
Dormitory or commuter towns or cities, e.g. Soweto
In an exam, you may be asked to identify the type of trade and transport city in a diagram. If a key is given, look at it carefully to help you answer the question. Learn the information above to help you answer this question. 3.3.3 Structure of an urban area The study of an urban area involves focusing on the following three aspects:
Urban profile
Urban street patterns
Urban land use zones
Urban profile An urban profile is a view of the urban area from the side, like looking at the side view of a person’s face. We call the side view a profile. A profile is seen in cross section drawings. When we study an urban profile we take note of the height, the density of the buildings, and land value.
Looking at the city from the centre towards the outskirts The height of the buildings decreases the further away you go from the centre of the city. The density (how many buildings there are in an area) also decreases the further you go from the city centre. The reason for the decrease in density and height is because land value decreases as you move away from the centre of the city.
Looking at a city from the outskirts towards the centre The height of the buildings increases the closer you get to the city centre. The density of the buildings also increases the closer you get to the city centre.
Thinking about land value Land value in the centre of the city is very high because it is in high demand (lots of people value it and want to live or work there). The land value decreases the further you go from the city centre. The density and height in the centre of the city is highest because of the high land value. People must make maximum use of the land. This is why there are many high-rise buildings in the city centre. Due to the high land value in the city centre, certain functions will move to the outskirts of the city, such as factories, businesses and residential (houses). Factories and business are often located in specific areas known as industrial or office parks. Houses are located in residential suburbs.
Figure 3.3.3B below shows the urban profile and how the land value decreases from the central business district (CBD) towards the outskirts of the urban area. In an exam you may be asked to describe how the building density or buildings might change as you move away from the CBD. You may also be asked to explain why the height or density of buildings changes. Learn the information above to help you answer this question.
Activity 3.4
On the urban profile shown in Figure 3.3.3B on page 56 draw a line graph to show how land value changes as you move towards the CBD. (1 × 2 = 2)
How does building density change as you move towards the centre of the city? (1 × 2 = 2)
Explain your answer in question 2. (2 × 2 = 4)
Why would an office park move away from the Central Business District? (2 × 2 = 4) [12]
Apply your understanding of urban profiles by completing Activity 3.4.
Answers to activity 3.4
The density of the buildings increases. (2)
The land is very expensive in the CBD so many buildings are built closer together and on smaller pieces of land. (4)
Land value is cheaper /There is less traffic congestion / It is closer to clients /There is less noise /There is more parking(any 2) (4) [12]
Urban street patterns The structure of an urban area can be studied from above by looking at the patterns formed by the streets of the urban area. The layout or arrangement of the roads is called the street pattern. In this section we focus on four street patterns:
Gridiron
Radial
Planned irregular
Unplanned irregular
Study Figures 3.3.3A to D to G (below and on page 58) to understand the four street patterns.
Gridiron street pattern
The roads intersect at right angles, forming rectangular blocks.
Found in the CBD and older cities
Advantages of the gridiron street pattern
Easy to find way around (cannot get lost)
Land can be divided up easily
Can be converted into one-way streets to ease traffic congestion
Shorter distance to travel
Little wastage of land
Disadvantages of the gridiron street pattern
Traffic congestion as traffic stops at every intersection
More accidents because of intersections
Monotonous (boring) suburb layout
In Paper 1 or Paper 2 you may be asked to identify the street pattern and state the advantages and disadvantages of the street pattern. You may also be asked to give the age of a settlement based on the street pattern in the settlement.
Radial street pattern
The roads spread out from a central point, similar to a spider’s web.
Found in very old cities like Paris in Europe or Kimberley in South Africa. It is also found in more recently planned cities like Sasolburg in South Africa.
Advantages of the radial street pattern
Easier flow of traffic
All roads lead to central point in town, for example a place of worship, monument, town square, etc.
Disadvantages of the radial street pattern
Traffic jams are common as all roads lead to the centre
Traffic is slow as there are no shortcuts
Space is wasted
Planned irregular street pattern
The roads have few intersections and curve a lot.
Found in modern cities and newer suburbs
Advantages of the planned irregular street pattern
Improves the flow of traffic
Roads are quieter because there are fewer intersections and less through-traffic
Interesting suburb layout because of unexpected turns in the road
Accommodates the nature of the topography
Disadvantages of the planned irregular street pattern
It is easy to get lost.
It is not easy to subdivide or expand.
Unplanned irregular street pattern
There is no clear design or plan to these roads.
Typical of informal settlements
Advantages of the unplanned street pattern
One of a kind (unique) pattern
Disadvantages of the unplanned street pattern
Traffic congestion
Unplanned/no order
Get lost easily
Urban land use zones The structure of an urban area can be studied by looking at the different land use zones in a city. A land use zone is an area which has features that define its function. For example, a residential area is made up of houses or flats, recreational areas, schools and shops. These features tell us that people live in the area. Another example is an industrial area, which is made up of many large buildings (factories), major transport routes and few open or green areas. Urban street patterns will be tested in activity 3.5 in the mapwork interpretation of settlement based on the Nelspruit map.
The photographs and some orthophotos in Figures 3.3.3H (i)–(xiv) below show different land use zones and their features. An orthophoto is an aerial photograph that has been geometrically corrected so that the scale is uniform and there is no visual distortion. Remember, aerial means ‘seen from above’.
Description
Photograph
Orthophoto
Central Business District (CBD)
In the city centre
Highest land values
Most accessible
Highest building density
Tallest buildings
Transition zone
Zone of mixed and changing land use, e.g. residential becoming commercial Often a zone of decay
Landlords are not maintaining the area or buildings.
Working class residents live here, in high-density flats or small houses.
Light industry
Often near the CBD or in planned industrial estates (areas where government plans to provide needed power and transport for factories)
Found near road transport as raw materials are often transported more easily in this way
Little noise and air pollution created by these industries
Heavy industry
Found on the outskirts of the city where land is cheapest Found near major road and rail networks for transport of raw materials and finished products
Often low-income housing is found nearby
Heavy air and noise pollution
Needs to be on flat land, near a water source
Middle- to high-income residential/upper class residential
Found away from the CBD
Often has a good view
Townhouses and big houses
Larger properties as more space is available
Good services and facilities, including recreation areas
Low-income residential/working class residential
Buildings very close together
Close to business area
Fewer facilities and poor services
Small blocks
Buildings look the same
Informal settlement
Found on the city outskirts
No service delivery (no roads, sanitation, water, electricity or schools)
High poverty levels
High crime rates
Houses are built out of plastic, wood, zinc, etc
Unhealthy conditions
Very dense housing with unplanned street patterns
Green belt/recreation
No buildings in this area
Used for public gardens, parks and sports fields. Area has many trees and lawns.
Helps to clean the air in urban areas
Calms traffic and reduces noise levels
Rural urban fringe
Mixed land use with both urban and rural functions
Urban functions like rubbish dumps, airports, cemeteries and golf courses
Land use starting to change from rural to urban as city expands
Large properties because land here is often cheaper
Less developed areas
Plots and smallholdings
See if you can find examples of these land use zones in the area where you live.
Land use models Land use models are simplified diagrams which are used to represent the pattern of land use functions within a city or a town. It should be remembered that these are a simplification of reality and it is unlikely that any model will fit every town or a city well. The urban models listed below are a few examples of the currently used urban models in the world. They are:
Multiple nuclei model
The modern American-Western city model
Third world city model
South African city model.
As cities developed and changed over time, people designed land use models to represent the patterns of land use at that time. Today most cities fit the multiple nuclei model. In developing countries cities have a different pattern, with sections that are well developed and defined (for example, areas where the colonial powers lived), and sections that are unplanned and irregular (for example, areas where the indigenous people lived). The irregular sections have grown due to rural-urban migration. South African cities have a completely different pattern due to apartheid laws like the Group Areas Act. Our cities have a multiple nuclei pattern with some additions – see Figure 3.3.3K.
Land use zones and mapwork interpretation It is important that you understand how to identify land use zones on a topographic map or orthophoto, as this is a frequently asked question in the Mapwork section of the exam (Paper 2). Central Business District
In the centre of the town
Has a gridiron pattern
Transport routes meet here
Working class residential zone
Near CBD or industrial area or sewage disposal works or railway line
Very small blocks (grey blocks on a map show built-up areas)
Upper class residential areas
On outskirts of town (but not near factories or sewage works)
Near to golf courses or the sea
Large grey blocks
Heavy industry
On outskirts of town
Next to main transport routes (highway or railroad)
Near a river
Indicated by large black blocks on the map
In Paper 1 and Paper 2 you may be asked to identify the land use zones seen in diagrams, cartoons, photographs and on a topographic map or on an orthophoto. You may also be asked to describe the characteristics of the land use zone. Learn the above information to help you answer the question.

Answers to activity 3.5
Nelspruit/Mbombela is the capital of Mpumalanga province. (2)
Analysis of the site of Nelspruit/Mbombela:
Near water from the river
Arable land from the river valley
Possible building material from the surrounding hills
Possible fuel from the vegetation on the slopes (8)
Discussion of the situation of Nelspruit/Mbombela:
Topography: It is on the valley floor so easy to establish/ Gap city between the mountains
Gradient: The city is built on flat land for the large buildings/Residential areas are more on the slopes
River: Buildings on the inner bank away from possible flooding
Transport: On the main road to Mozambique on N4/ Links to the west–east and north–south/Part of Maputo Corridor (any 3 facts) (6)
Block C2 is a nucleated settlement pattern. The buildings are close to one another. (4)
The settlement in block B3 has a linear shape. It lies along the road/along a contour so that it is easy to build on the same height above sea level/altitude.33 (4)
The type of farming in block C3 is commercial farming. The farm is large/The farmer lives on his farm and has maximum control/The farm is near to the road for easy transport. (any 3 facts) (6)
The farm Friedenheim in block C5 is an experimental farm. It has a research/education function. (2)
This farm can help to prevent rural–urban migration because: It creates work for the people living in the area and people can migrate back to the area/It supports Agenda 21, enabling people to become more independent or able to make a living. (any 1 fact) (2)
Nelspruit (Mbombela) can be classified as any one of the following: Central place – there is a lot of farming in the area so Nelspruit offers urban services to the surrounding rural area, e.g. market for farm produce, schools for rural children to attend. Trade and transport city – it is built where two major roads meet Gap city – it is built in the valley between mountains. (any 1) (4)
The land use zone known as the CBD is in block E4 on the map (2)
Simple cross section sketch to illustrate the urban profile of this land use zone:
This zone has a gridiron street pattern.
Advantages (any 2)
Disadvantages (any 2)
Easy to find your way around (cannot get lost) Land can be divided up easily Can be converted into oneway streets to ease traffic congestion Shorter distance to travel Little wastage of land
Traffic congestion as traffic stops at every intersection More accidents because of intersections Heavy traffic causes road rage More pollution from cars Monotonous (boring) town layout (10)
West Acres is an example of an upper income residential area. Two reasons are evident on the map to support this statement:
Away from the CBD
It has large blocks of land between the roads.
Street pattern plan is irregular
It is on the warmer, north-facing slope so land will be more expensive.
Away from pollution and noise (any 2) (4)
Questions based on the orthophoto:
Land use found at A, B, C and D:
= Transport (railway station)/Industrial
= Commercial/Business – CBD
= Residential
= Recreation/Showground (8)
The best place for a shopping mall for the residents of West Acres would be near E on the orthophoto. The reasons are as follows:
The land is not being used for other purposes.
It is near a road so people living nearby can get there easily.
It is close to the suburb West Acres.
The land here is quite flat (as indicated by the contours that are far apart). (any 3 reasons) (6) [70]
Study Tables 3.5 to 3.7 to learn about the causes, effects and solutions to these three urban problems. 3.3.4 Urban settlement problems As an urban area grows and more people move into the area, certain problems are created and get worse as the city gets bigger. These problems are often worse in the CBD. In this section we focus on the following three urban problems:
Congestion
Urban decay
Centralisation
Problem: Congestion (too many cars on the roads)
Causes
Effect
Solution
Too many people using own cars
Not enough public transport
Old street planning
Increased air pollution
More accidents
More stress and health problems; road rage
Improve public transport
Have lift schemes
Encourage some businesses to move out of the CBD
Synchronize traffic lights
Table 3.5: Causes, effects and solutions to the urban problem of congestion
Problem: Urban decay (where parts of the city are not looked after or are over-used)
Causes
Effect
Solution
CBD moving into residential areas
Too many people living in the city
Unoccupied/empty buildings
Slums develop
Services and facilities decline
Increased pollution
Area becomes dirty and neglected (not looked after)
Get people in slums to help fix up their area, increase their ownership of buildings
Improve and upgrade services and facilities
Table 3.6: Causes, effects and solutions to the urban problem of urban decay
Problem: Centralisation (too many people and activities moving into the city, close to centre)
Causes
Effect
Solution
High demand for land in the city
Too many people living in the city
Increased pollution
Increase in health problems
Increased destruction of the environment
Overuse of resources
Production of too much waste
Move certain functions out of the city
Stricter controls on all types of pollution
Develop more green belts
Table 3.7: Causes, effects and solutions to the urban problem of centralisation In an exam you may be asked to state the causes or effect or solution to an urban problem. You may also be asked to describe the causes or effect or solution to an urban problem in a paragraph.
3.3.5 Economic, social and environmental injustice In geography you are often asked to describe, explain, or discuss the effect, impact, or injustice of particular phenomena. To do this, we first need to understand the meanings of these words.
Injustice: inequity, unfairness, unjustness, wrong, grievance; means an act that inflicts undeserved hurt. Injustice applies to any act that involves unfairness to another or violation of one’s rights
Opposite of injustice: equity, fairness, justice.
Economic injustice: when different people have different levels of income in a society.
Social Injustice: the distribution of advantages and disadvantages within a society.
Environmental injustice: the unfair distribution of environmental benefits and burdens. Environmental justice is the fair treatment and meaningful involvement of all people regardless of race, colour, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.
Impact: the effect or impression of one thing on another.
Effect: something brought about by a cause or agent; a result or outcome.
In Geography when a question refers to economic, social and environmental factors, impacts or injustices the term relates to the following:
Economic: this term deals with the making of or losing money by business, countries, and individuals. It includes economic activities (primary, secondary, and tertiary activities). It is concerned with the human-made environment; the infrastructure and buildings.
Social: this term relates or deals with people, demographic factors (birth rates, death rates, income, literacy levels and employment), and basic needs.
Environmental: of, relating to, or associated with the environment.
In a test or exam the question would be as shown below. Possible answers are given.
Discuss the economic, social, and environmental injustices of the following: Or Discuss the economic, social, and environmental impacts or effects of the following:
