Settlement and population geography questions in Section B of ECZ Geography Paper 2 carry 12 marks. Examiners expect candidates to use specific geographical terms (e.g., nucleated, ribbon development, primate city, counter-urbanisation) and reference Zambian case studies like Lusaka, Kitwe, and Solwezi.
Encourage learners to sketch simple settlement diagrams in their answer scripts. A labeled sketch showing clustered buildings around a central borehole or a linear line along the Great North Road earns quick schematic marks.

1. Classification of Settlements: Rural vs Urban
A settlement is a place where people live, establish homes, and carry out economic and social activities. In ECZ Geography, settlements are broadly categorized into two types:
| Characteristic | Rural Settlements | Urban Settlements |
|---|---|---|
| Primary Occupation | Predominantly primary industries: farming, fishing, forestry, livestock rearing. | Secondary and tertiary sectors: manufacturing, commerce, civil service, banking, transport. |
| Population Density | Low to moderate population density with vast open land. | High population density with closely built multi-storey infrastructure. |
| Service Infrastructure | Basic services; often unpaved roads, borehole water, limited grid electricity. | Advanced infrastructure; piped treated water, sewerage, tarred roads, fiber internet. |
| Zambian Examples | Villages in Gwembe, Mpika, Kaoma, Lundazi. | Lusaka, Kitwe, Ndola, Livingstone, Solwezi. |
2. Rural Settlement Patterns
The layout or spatial arrangement of buildings in a landscape forms distinct settlement patterns:
1. Nucleated (Clustered)
Dwellings are tightly grouped around a central focus point such as a perennial water well, school, chief's palace, or church.
Advantage: Facilitates communal defense, easy sharing of social amenities, and social cohesion.
2. Dispersed (Scattered)
Dwellings are spaced far apart, separated by hundreds of meters or kilometers of farmland or bush.
Advantage: Prevents disease spread; farmers live directly on their large commercial agricultural fields (e.g., Mkushi farm blocks).
3. Linear (Ribbon)
Buildings are constructed in a straight line along a transport axis such as a paved road, railway line, river bank, or canal.
Advantage: Immediate access to public transport, roadside trading, and river water transport.
3. Factors Influencing the Site and Growth of Settlements
Examiners routinely ask candidates to explain why a particular town or village was originally founded at a specific location:
- Water Supply: Settlements need reliable freshwater for domestic cooking, livestock, and small gardens. Historically, towns grew near rivers (e.g., Livingstone near the Zambezi).
- Relief / Elevation: Flat or gently undulating plateaus facilitate building construction and road networks, while floodplains are avoided except during dry seasons.
- Mineral Wealth: The discovery of rich copper deposits was the sole catalyst for the rapid founding of Copperbelt towns (Kitwe, Mufulira, Chingola, Luanshya) and modern Solwezi.
- Nodal & Route Junctions: Towns develop where major trade routes intersect. Kapiri Mposhi developed as a vital junction linking the Great North Road and TAZARA railway.
- Defense & Safety: Historically, settlements were built on hill summits or islands (e.g., on Lake Bangweulu) to defend against warring tribes and slave raiders.
4. Rapid Urbanisation & Rural-Urban Migration in Zambia
Urbanisation is the increase in the proportion of a country's total population living in towns and cities. Zambia is one of the most urbanized countries in Sub-Saharan Africa, with over 45% of its citizens residing in urban areas.
| Push Factors (Repelling from Rural Areas) | Pull Factors (Attracting to Urban Centers) |
|---|---|
| Prolonged droughts and low, unpredictable crop yields. | Prospects of formal and informal wage-earning employment. |
| Inadequate tertiary and vocational educational institutions. | Concentration of universities, colleges, and technical institutes. |
| Lack of electricity, poor recreational amenities, and isolation. | Modern amenities, piped water, electrified housing, entertainment. |
| Limited healthcare facilities and specialist hospitals. | Proximity to university teaching hospitals and modern health clinics. |
5. Socio-Economic & Environmental Challenges in Zambian Cities
When the rate of population influx outpaces the capacity of municipal councils to provide infrastructure, severe urban crises emerge:
Major Urban Crises in Lusaka and Copperbelt:
- Proliferation of Informal Squatter Settlements: Over 60% of Lusaka's urban population resides in unplanned peri-urban compounds (e.g., Misisi, Kanyama, Chibolya) lacking legal title deeds.
- Waterborne Disease Outbreaks: Dense shallow pit latrines situated adjacent to shallow hand-dug wells cause seasonal contamination, triggering perennial cholera and typhoid epidemics during the rainy season.
- Severe Traffic Congestion: Outdated road arteries designed in the 1960s struggle to accommodate surging motor vehicle numbers, causing prolonged traffic gridlocks on major routes.
- High Youth Unemployment & Crime: Rapid migration without corresponding industrial factory growth leads to swelling informal street vending, poverty, and opportunistic crime.
- Inadequate Solid Waste Management: Municipal councils struggle with refuse collection, resulting in indiscriminate garbage dumping that blocks stormwater drainage channels.
6. Solutions: Squatter Upgrading & Sustainable Urban Planning
Rather than forceful bulldozing and eviction—which renders thousands homeless—the Zambian government adopted Squatter Upgrading Programs backed by the Housing (Statutory and Improvement Areas) Act:
Key Measures for Sustainable Urban Development:
- Infrastructure Provision: Paving ring roads, installing overhead street lighting, and building concrete lined drainage canals (such as the Lusaka Sanitation Program).
- Clean Piped Water Kiosks: Establishing regulated water kiosks managed by commercial utilities (e.g., Lusaka Water Supply and Sanitation Company - LWSC) to replace contaminated shallow wells.
- Issuance of Occupancy Licenses: Providing residents with 30-year statutory occupancy certificates, giving families legal security of tenure to invest in permanent brick building materials.
- Decentralization of Industry: Offering tax incentives to manufacturing companies to set up factories in provincial capitals (Chipata, Choma, Kasama, Solwezi) to curb migration into Lusaka.
7. Worked 12-Mark Examination Question with Marking Scheme
"Explain the problems associated with rapid urbanisation in Zambia and outline four measures being implemented to address these challenges." [12 Marks]
Examiner Mark Breakdown:
- Problems of Urbanisation (7 Marks): Candidate must identify and explain 4 to 5 distinct problems with local context:
- Shortage of decent housing leading to growth of shanty compounds like Kanyama and Misisi [2 marks].
- Outbreaks of waterborne diseases (cholera/dysentery) due to proximity of pit latrines to shallow water wells [2 marks].
- High unemployment rates forcing youth into low-income street vending and crime [1 mark].
- Severe traffic congestion and strain on public transportation along major corridors [1 mark].
- Environmental degradation, air pollution from vehicles, and uncollected solid waste clogging drainage systems [1 mark].
- Measures Being Implemented (5 Marks):
- Squatter upgrading through municipal council infrastructure interventions [1 mark].
- Construction of piped communal water kiosks and public waterborne sewer systems [1 mark].
- Road expansion projects (e.g., Lusaka Decongestion Project flyover bridges) to ease vehicular gridlock [1 mark].
- Rural electrification programs (REA) and CDF community grants to stimulate rural employment and reduce outbound migration [2 marks].
8. Frequently Asked Questions
What is a 'Primate City' in geography?
A primate city is a country's leading city that is disproportionately larger than any other city in the national urban hierarchy (in terms of population, economic output, and political influence). In Zambia, Lusaka exhibits strong primate city characteristics.
What is the difference between a site and a situation of a settlement?
The site refers to the actual physical ground on which a settlement is built (e.g., altitude, slope, soil type). The situation refers to the settlement's location relative to surrounding human and physical features (e.g., transport routes, nearby towns, and raw materials).
What is counter-urbanisation?
Counter-urbanisation is the demographic process whereby people migrate out of congested metropolitan centers to live in smaller surrounding rural towns or peri-urban smallholdings.
