Settlements

Concepts of Settlement

Definition of Settlement

A settlement is a place or location where people live and establish their livelihood. Settlements can come in different sizes, from a single house in a remote area to a large megacity. Settlements may be temporary or permanent; for example, refugee camps often start as temporary settlements but can become permanent over time. The actual piece of land upon which a settlement is built is known as the settlement site.

Settlement Patterns

Settlements usually develop in particular patterns, though not always. These patterns include:

• Nucleated Settlements: Buildings are clustered around a central point, such as a market square.
• Linear Settlements: Buildings are arranged in a line, usually along a river or road.
• Dispersed Settlements: Buildings are spread out or scattered, often found in remote, sparsely populated areas.

Categories, Types, and Characteristics of Settlements

Types of Settlements

There are two main types of settlements: urban and rural.

1. Urban Settlements:

• Geographical areas with dynamic boundaries.
• Growth is due to birth rate and boundary changes.
• Population data is important for social, environmental, and demographic studies.
• Characteristics:
  • Boundaries change over time with construction and population changes.
  • Independent of administrative boundaries.
  • Dense industrial activities.
  • Major trading activities.

1. Rural Settlements:

• Areas with less than 10,000 population, comprising small towns, villages, and homesteads.
• Characteristics:
  • Sparsely populated.
  • Major activity is agriculture.
  • In Tanzania, 80% of the population lives in rural areas, supplementing farming with activities like weaving, carving, fishing, and timber extraction.

Settlement Patterns

Settlement patterns refer to the layout of dwellings in a particular place, influenced by topography, availability of suitable land for farming, transport routes, communication lines, and human factors like population increase.

Types of Settlement Patterns

1. Nucleated Settlement Pattern:

• Cluster of dwellings and other buildings in one place.
• Develop due to the availability of social services, industrial plants, and limited building land.
• Examples: Mwadui in Tanzania, Kimberley in South Africa.

1. Linear Settlement Pattern:

• Develop along communication lines or physical features like rivers.
• Buildings arranged in a line along roads, rivers, canals, or coastlines.
• Examples: Coastal East Africa, shores of Lake Tanganyika, parts of Lake Victoria.

1. Dispersed Settlement Pattern:

• Also known as scattered settlement pattern.
• Houses and other structures are scattered, separated by physical features like valleys, rivers, and ridges.
• Common in areas where people own individual plots of land.

Functions of Settlements and Their Importance

The functions of settlements describe all the activities that occur within them. Common functional classifications include rural settlements and institutional settlements, established for specific purposes such as:

• Market Towns: Centers for sale and distribution.
• Mining Towns: Located near natural resources.
• Manufacturing and Industrial Towns: Grown around raw material sources.
• Route Centers: Located at transportation nodal points.
• Administrative Centers: Provide regional or national administrative services.
• Port Centers: Initially for raw materials, goods, and passengers, now also for business.

Growth of Settlements

Growth refers to the increase or expansion of places where people live and engage in economic activities. Settlement growth is dynamic, changing over time due to various factors.

Factors Influencing the Growth of Settlements

1. Social Services: Availability of health centers, schools, electricity, and water supply attracts people.
2. Climate Conditions: Favorable rainfall and temperature support farming, attracting people.
3. Relief: Gentle slopes are ideal for building; steep slopes are less inhabited.
4. Vegetation Cover: Thick vegetation discourages settlement; dense forests are often inaccessible.
5. Political Factors: Settlements may be influenced by political decisions (e.g., ujamaa villages in Tanzania).
6. Economic Factors: Economic opportunities attract people (e.g., mining towns like Mwadui).
7. Cultural Factors: Cultural beliefs may prohibit settlement in certain areas.
8. Historical Factors: Historical movements and conflicts have influenced current settlements.

Social and Economic Problems Associated with Urban Growth

Urbanization brings numerous problems, including environmental degradation, crime, inadequate housing, traffic congestion, unemployment, immorality, shortage of public utilities, and emergence of street children.

1. Overcrowding: Increased birth rate and immigration lead to overcrowding.
2. Political Instability: Crime and other behaviors lead to political instability.
3. Disease Outbreaks: Population pressure leads to outbreaks like cholera and malaria.
4. Unemployment: Migration to urban centers creates job shortages.
5. Traffic Congestion: High number of vehicles causes congestion and pollution.
6. Shortage of Social Services: Water and school shortages due to increased population.
7. Emergence of Street Children: Family conflicts and lack of social services lead to street children.

Solutions to Urban Growth Problems

1. Improvement of Social Services: Enhance water, electricity, schools, and infrastructure.
2. Creation of Employment Opportunities: Increase investments in industries and agriculture.
3. Good Urban Planning: Ensure well-planned housing and infrastructure.
4. Improvement of Infrastructure: Accommodate more vehicles and improve road systems.
5. Family Planning: Reduce family sizes to manage social services and employment better.
