• UNIT 11: URBANISATION IN THE WORLD

    Key unit competency:

    By the end of this unit, I should be able to discuss the impact of settlement and

    urbanization on the sustainable development of different countries.

    The concept of urbanization is well defined from the concept of settlement.

    A settlement refers to a place where people live. It can be large or small, permanent

    or temporary. A settlement also means the process of settling in a given a place.

    Settlement is associated with the concepts of shelter, infrastructure and community

    services like health, culture and education. There are two types of settlements: rural

    settlement and urban settlement.

    The term ‘urban’, is opposed to rural which can refer to isolated building, hamlet,

    village, small market town while urban is related to towns or cities. Urban settlement

    is large nucleated settlement in which most of the employed inhabitants are engaged

    in non-agricultural activities. Urban areas may be defined by national governments

    according to different criteria; for example, size of the population, population

    density, occupation of the people, and type of local government. However, the

    United Nation defines an urban place as a permanent settlement with not less than

    20,000 inhabitants.

    Urbanisation is a process of increasing number of people that live in urban areas

    in a country or the process of growing of cities and towns, therefore, the societies

    becoming more urban. For example, according to 2012 national census, 16.5 % of

    Rwandans live in urban areas. Urbanisation refers also to the physical expansion of

    urban areas, or the increase in number of urban areas or towns.

    11.1. Rural settlement

    Learning activity 11.1

    With reference to your own observation and the knowledge acquired from past

    studies

    1. What do you understand by the term rural settlement?

    2. Describe the different types of rural settlement.

    3. What are the factors that would influence someone to create a settlement

    somewhere?

    Rural settlement is a sparsely populated community that exists in each area. The

    population density in rural areas is very low compared to the urban areas. In such

    areas houses are scattered. The largest land use is agriculture. This means that

    most people are engaged in agricultural activities and other related activities

    such as livestock farming, fishing, mining, hunting etc. Sometimes, there are larger

    agricultural agglomerations. However, this cannot be considered as urban centres

    because of the primary activity common in that region.

    11.1.1. Types of rural settlement

    The following are the various types of rural settlements:

    (i) Nucleated settlements pattern: It is also known as clustered or grouped

    settlements. Houses are concentrated in one place without proper arrangement.

    Nucleated or clustered settlements often form at crossroads or route centres. These

    types of settlements are known as “Imidugudu” in Rwanda. Socially, the people are

    closely knit

    (ii) Linear settlement pattern: This is where houses are well planned and

    concentrated along the communication lines like roads, railway stations or along

    the coast. The fields extend behind the buildings in long, narrow strips. These are

    mainly influenced by economic factors. Linear settlement patterns are also known

    as ribbon settlement. 

    (iii) Dispersed /scattered settlement pattern: This is where houses are scattered

    all over the area. The settlements are located at distance apart from each other. This

    type of settlement dominates in areas where agricultural and livestock activities are

    dominant. 

    (iv) Isolated settlement pattern: This is a type of settlement which is characterized

    by people who are hunters, shifting cultivators and food gatherers or other specific

    activity. That is, people who are socially isolated by other people.

    (v) Ring settlement pattern: In this type of settlement, houses make a circle. There

    is an open ground at the centre.

    Planned settlement pattern: These are settlements which are deliberately

    designed to assume a certain shape or pattern. They may develop according to

    the government’s plan. The emergence of the various patterns of settlement is

    influenced by the following factors.

    11.1.2. Factors influencing rural settlement

    A place where a settlement starts is called a site of a settlement. Any settlement site

    is chosen because it has a lot of good reasons for locating a settlement there. The

    following are the main factors influencing rural settlement:

    – Water supply: Water is an important human need. It helps in deciding where

    a settlement might be located. Thus, most settlements are located near water

    sources such as rivers and lakes.

    – Soil fertility: Farmers often choose to settle at points where the land is

    suitable for crop growing as agriculture and livestock are the key activities in

    rural areas.

    – Security: More people settle in areas where there is peace. They can live

    without fear of anything.

    – Building materials like timber and stone attract people to settle where they

    are easily available.

    – Absence of natural hazards: few people live in places likely to be hit by

    natural hazards.

    – Climate: People are much more attracted to settle in temperate climatic areas.

    Few people live in very hot or very cold areas.

    – Means of transport and services: The presence of roads, schools and hospitals

    attract many people for settling around them.

    – Presence of minerals: People like to settle where mining activities are taking

    places as jobs are available in those areas. In those areas, the markets, schools

    and hospitals are built to serve them.

    – Government policy: The government decides where people should and

    should not settle. This is done as part of planning.

    – Cultural and social factors: For example, a father dividing his land among his

    children. The children settle in the same area.

    – Relief: Few people live on the steep slopes of mountains. On the other hand,

    Flat land is easier to build on and it is good for growing crops. This explains

    why many people live in plateaus and the plains.

    11.1.3. Effects of rural settlements

    The concentration of people in rural areas has both negative and positive effects:

    Positive effects

    – The development of rural settlement, especially grouped and planned

    settlement facilitates the establishment of social facilities. Facilities such as

    schools, shops, hospitals, electricity, water points and other basic infrastructure

    are usually established and made available to the entire settlement.

    – Rural settlement leads to the development of trading activities with

    surrounding settlements and urban centres.

    – Rural settlement produces food stuffs to the urban areas.

    – Rural settlements provide or supply the urban centers with affordable labour

    force.

    Negative effects

    – Rural settlements, especially dispersed settlements experience shortage/lack

    of basic infrastructures such as water, electricity, roads, etc.

    – They are exposed to pollution resulting from uncollected garbage and

    contaminated water.

    – Rural settlement experience shortage of social services such as hospitals,

    schools and markets. People make a long distance to access such services.

    – In rural settlement people fight for land. Therefore, constant land disputes are

    witnessed.

    – There is high spread of diseases like dysentery, cholera, and malaria due to

    poor hygiene and compaction of individuals.

    – There is environmental degradation due to high demand for building materials,

    firewood, charcoal which further results into soil erosion, reduction in rainfall

    and landslides.

    – The family plots are fragmented. This makes them to be too small for

    commercial mechanized farming.

    11.1.4. Solutions to the problems affecting rural settlement

    – To avail the basic infrastructures such as water, electricity, roads, etc. in the

    areas to be settled.

    – Construction of social facilities and services such as hospitals, schools, market.

    – Regular registration of land to reduce the conflicts related to the land

    ownership and use.

    – Preparation of master plan and land use guide for all country to avoid

    unplanned settlement.

    – Making environment management policies to avoid environmental

    degradation.

    – Establish good governance to avoid any kind of division, insecurity in

    population, etc.

    – Sensitizing the rural settlers on the most effective way of managing the

    environment.

    Application activity 11.1

    11.2.1. Definition of basic terms

    Different terms are used to express urban centres according to their size or

    characteristics. The following are the commonly used terms.

    – Trading center: A trading center is a given settlement whose major occupation

    is associated with trading activities. It may be an area within a city or located

    away from the main city.

    – Town: It is the smallest unit of urban settlement. Here, urban functions are

    well marked although the possibility of some rural activities existing is not

    ruled out.

    – Town board: It is the legislative body that governs a town/city.

    – Municipality: A municipality is a political subdivision of a state for a specific

    population concentration in a defined area. The municipality is bigger than a

    town in terms of covered area and the size of population settled in that area.

    – City: The term city is derived from the Latin word ‘civitas’ which means

    community/city/town or state. It is a full-fledged urban agglomeration showing

    predominance of urban occupations and complex internal structure. Any town

    with a population of 100,000 inhabitants/dwellers or above is termed as city.

    – Agglomeration: It is an extended city or town area comprising the built-up

    area of a central place (usually a municipality) and some suburbs linked by

    continuous urban area.

    – Megalopolis: It denotes a large urban region formed by the out-growth of

    many metropolises. A  megalopolis (sometimes called a megapolis; also,

    megaregion, or super city) is typically defined as a chain of roughly adjacent

    metropolitan areas, which may be somewhat separated or may merge into a

    continuous urban region. Megalopolis also expresses the full mature stage of

    urban growth.

    – Conurbation: It is a large continuous built-up area formed by the joining

    together of several urban settlements or town. It is an urban region consisting

    of a large metropolis and several small towns huddled together.

    – Suburb: It is a mixed-use or residential area, existing either as part of a city or

    urban area or as a separate residential community within commuting distance

    of a city. Some suburbs have a degree of political autonomy, and most have

    lower population density than inner city neighbourhoods.

    – Green city: It refers to a broader metropolitan area. For example, “Chicago”

    represents the greater metropolitan area surrounding the city of Chicago. It

    aims at informing and stimulating the interest with authorities, organizations

    and companies which are professionally involved in planning and developing

    the urban area, ensuring green belts (Areas covered with selected flora) will be

    applied appropriately.

    – Slum: It is defined as a highly populated urban residential area consisting

    mostly of closely packed, dilapidated housing units in a situation of deteriorated

    or incomplete infrastructure, inhabited primarily by impoverished persons or

    low income earners. 

    11.2.2. Location of major world urban centres and ports

    The major world urban centres and ports are considered as megalopolises which are

    large urban regions formed by the out-growth of urban center.

    – The most known urban regions are developed along the North-Eastern sea

    board of USA. This includes: Boston, Massachusetts, New York City, Philadelphia,

    Baltimore ending in Washington, D.C. and Northern Virginia

    – The urban regions in Eastern Asia which include the urban centres of China,

    Japan, Singapore, India, South and North Korea.

    – The Western European urban centres including cities of Germany, U.K, France,

    Netherlands, Belgium, Italy, etc.

    – The South Africa urban centres including: Pretoria, Johannesburg, Durban,

    Cape Town, etc.

    – The Urban centres in Northern Africa including the cities of Libya, Morocco,

    Tunisia, Algeria and Egypt.

    11.2.3. Factors influencing urban development in the world

    Urbanization is the function of socio-economic changes that take place through

    time. The following are its determinants, which are mainly economic, social and

    demographic.

    – The economic determinants are the types of economy, degree of

    commercialization of agriculture, the extent of diversification of economy,

    the changing size of agricultural landholdings, the stage of economic

    advancement and the degree of development of means of transportation and

    communication.

    – The social factors that determine the nature and magnitude of urbanization

    are the degree of socio-economic awakening, the social value system, the

    stage of technological advancement, the public policies and the government

    decisions.

    – Among the demographic factors, the rate of population growth, magnitude of

    migration and pressure of population are significant.

    – Improvement of transportation can bring raw materials to any point quite

    cheaply.

    – Improvement of information and technology which raises the population

    awareness about the available opportunities in other urban centres.

    11.2.4. Functions of urban centres and ports

    Most towns perform several functions. In some towns, one activity is predominant,

    and the town is known for that function. But many towns are now multi-functional.

    The following are the most important functions that cities perform:

    11.2.5. Impact of world urbanization on the environment

     Urbanization might cause the following problems:

    – Urbanization results into pollution of land, air, water and noise. This is because

    of poor disposal of garbage from the domestic and industrial remaining. It

    also results into noise pollution from industry machineries, vehicles, and other

    means of transport,

    – High energy consumption increases the release of CO2 in the atmosphere.

    This leads to global warming.

    – Most people do not have access to safe drinking water especially in developing

    countries. Thus, poor sanitation and poor quality of drinking water result

    into water-borne diseases like Cholera, Typhoid, tuberculosis, dysentery and

    gastro-enteritis.

    – Sewage also provides nutrition to a vast array of microbes, bacteria and fungus

    adding to the eutrophication of surface water bodies, seriously affecting the

    human environment and the entire food web in the eco system. Even the

    ground contaminated by the industrial effluents in the atmosphere, brought

    down by precipitation.

    – Waste disposal is a major problem in large cities.

    in terms of economic development. They also face many common problems which

    include:

    – The loss of culture identity of the society: This is as result of the interaction of

    different cultures from different people including foreigners.

    – The pollution of land, air, water and noise: This is because of poor disposal of

    garbage and the existence of very many vehicles and industries.

    – The shortage of land for agriculture: As towns expand, land for agriculture is

    reduced in favour of settlement and this in turn may result into a decline in

    food production.

    – Unemployment and under employment: This is because of the high urban

    population that competes for the low employment opportunities.

    – Urbanization creates congestion especially during rush hours when people go

    to or come from the work.

    – The big number of population in Brasília, Johannesburg and Nairobi cities has

    led to the problems of insecurity. The security personnel are overwhelmed by

    the rising crime rates.

    Solutions to the problems facing cities in developing countries

    In order to overcome problems related to the development of urban centers in

    developing countries, both the government authorities and the inhabitants of

    those cities need to cooperate to find the appropriate solutions. Here are some of

    the solutions to the problems faced by cities:

    – The problem of accommodation can be solved or reduced by the construction

    of skyscrapers or stored houses which occupy little space on the ground and

    can accommodate very many people.

    – Enlargement of roads by constructing high ways and subways for vehicles and

    pedestrians in addition to strict laws governing traffic.

    – Enforcing tight security and punishing law breakers like those involved in

    robbery theft murder and prostitution.

    – Garbage within urban cities should be cleaned by forming cleaning association

    and be dumped in particular places where they are burnt or recycled into other

    useful products.

    – Attracting foreign investors to establish more industries both in rural and

    urban centers to provide employment to the majority and where necessary to

    form labour organizations.

    – Good urban planning strategies to avoid further slum development, digging

    water tunnels to direct water and replacing semi-permanent structures by

    permanent structures.

    and Nairobi cities respectively as big cities in developing country.

    End unit activities

    1. With reference to Kigali city explain why towns are constantly growing

    both in population and area.

    2. Analyse the major problems that are shared by both developed and

    developing countries cities.

    3. Suppose you are one of the urban planners, design a program that would

    address the problems caused by urbanization.

    4. Describe the different functions of urban centers. Give at least two cities

    as example for each function.

    5. Kigali is currently experiencing rapid urban development in our region.

    From the knowledge acquired in this unit, identify the major factors which

    are contributing to that urban development.
