G30: Urban Growth in LICs and NEEs
FoundationHigherAQAEdexcelOCREduqasCCEA
A case study of Lagos, Nigeria - its location and importance, causes of growth, opportunities created by urbanisation, challenges of urban growth, and urban planning strategies.
📍 Case Study: Lagos, Nigeria
Key Facts: Lagos is a megacity in Nigeria, West Africa. It is built on the coast of the Gulf of Guinea and on islands in Lagos Lagoon. With a population of approximately 15 million (metropolitan area), it is the largest city in sub-Saharan Africa and Nigeria's economic capital. Lagos grows by an estimated 77 people per hour.
Location and Importance
Located on the south-western coast of Nigeria, on the Gulf of Guinea (6.5°N, 3.4°E)
Built on the mainland and islands in Lagos Lagoon, connected by bridges
Former capital of Nigeria (moved to Abuja in 1991), but remains the commercial and economic hub
Generates approximately 25% of Nigeria's GDP and 65% of its industrial activity
Handles 80% of Nigeria's international trade through its ports (Apapa and Tin Can)
Home to the Nigerian Stock Exchange and headquarters of major banks and corporations
Major cultural centre: Nollywood (Nigeria's film industry) is based here, producing more films annually than Hollywood
📈 Causes of Growth
Rural-Urban Migration
Push factors from rural Nigeria: Poverty (rural incomes average $1.50/day), lack of education and healthcare, Boko Haram insurgency in the north, desertification in the north-east, lack of employment
Pull factors to Lagos: Job opportunities in oil, manufacturing and services; higher incomes (average $5-10/day); education (3 universities); healthcare; family connections; perception of modern lifestyle
Nigeria's oil boom (since 1970s) concentrated wealth and jobs in Lagos, attracting millions
Net migration adds approximately 500,000 people to Lagos each year
Natural Increase
Lagos has a very young population - median age is just 18 years
Birth rate is approximately 36 per 1,000 (vs UK rate of 11 per 1,000)
Death rate is approximately 10 per 1,000, giving a natural increase of 26 per 1,000
Natural increase accounts for roughly 60% of Lagos's annual population growth
The combination of migration and natural increase means Lagos adds approximately 600,000-700,000 people per year
Key Fact: Lagos was a small town of approximately 300,000 in 1950. By 2025, the metropolitan population is approximately 15 million - a 50-fold increase in 75 years. Projections suggest it could reach 25 million by 2035.
✅ Opportunities Created by Urbanisation
Economic Opportunities
Employment: Lagos generates 25% of Nigeria's GDP; opportunities in oil, manufacturing, services, tech and the informal sector
Informal economy: Provides livelihoods for an estimated 65% of the workforce - street trading, repair services, transport (okada motorbike taxis)
Tech hub: Yaba area is known as "Silicon Lagoon" - home to tech start-ups, co-working spaces and incubators
Ports and trade: Apapa and Tin Can ports handle 80% of Nigeria's imports, creating thousands of logistics jobs
Nollywood: The film industry employs over 1 million people and generates $600 million annually
Social Opportunities
Education: Three major universities (University of Lagos, Lagos State University, Yaba College of Technology) plus many private schools
Healthcare: Lagos University Teaching Hospital and numerous private clinics offer better healthcare than rural areas
Services: Access to electricity (though unreliable), mobile phone networks, internet and banking services
Social mobility: Migrants from rural areas can access opportunities for themselves and their children that are unavailable in villages
Cultural life: Vibrant music, art, food and entertainment scenes
Example: Makoko Floating School
Makoko is a slum community of approximately 250,000 people built on stilts over Lagos Lagoon. Despite extreme poverty, it has a vibrant informal economy based on fishing and trading. In 2013, the Makoko Floating School was built as an innovative community structure that could adapt to changing water levels. Although it collapsed in 2016, it demonstrated how communities and architects are developing creative solutions to Lagos's challenges.
❌ Challenges of Urban Growth
Housing and Slums
Over 60% of Lagos residents live in informal settlements (slums)
Makoko, Ajegunle and Ijora are among the largest slums
Housing is overcrowded - rooms often shared by 8-10 people
No security of tenure - residents can be evicted at any time
Government demolition of slums displaces thousands without providing alternatives
Water and Sanitation
Only approximately 10% of Lagos residents have access to piped water
Most people rely on boreholes, wells or water vendors (who charge 5-10 times the piped water rate)
Fewer than 40% of residents have access to adequate sanitation
Open defecation is common in slum areas, causing water contamination and disease
Cholera outbreaks occur regularly, especially during the rainy season
Traffic Congestion
Lagos is notorious for some of the worst traffic in the world
Average commute time is over 2 hours each way for many workers
Over 5 million cars on limited road infrastructure
Congestion costs the economy an estimated $8.5 billion per year
Okada (motorcycle taxi) bans have reduced transport options for the poor
Employment and Poverty
Formal sector cannot create enough jobs for the rapidly growing population
Unemployment rate estimated at 20-30% (official figures are lower)
Many work in the informal sector with no job security, pensions or labour rights
Youth unemployment is particularly high, contributing to crime
Waste Management
Lagos generates approximately 13,000 tonnes of solid waste per day
Only approximately 40% is formally collected and disposed of
Open dumping and burning are common, causing air and water pollution
Drainage channels blocked by waste cause severe flooding during rainy season
Challenge
Scale of Problem
Impact

Pollution; flooding; disease
🏗️ Urban Planning Strategies
Eko Atlantic
A new city being built on reclaimed land from the Atlantic Ocean
Designed for 250,000-500,000 residents, with commercial, residential and leisure areas
Promises reliable electricity, clean water and modern infrastructure
Criticised as a "city for the rich" - most Lagos residents cannot afford to live there
The Great Wall of Lagos (sea wall) protects the development from coastal flooding
Lagos Urban Transport Project
Bus Rapid Transit (BRT) system introduced in 2008 along Ikorodu Road
Carries approximately 200,000 passengers daily, reducing journey times
Lagos Light Rail (Blue Line) opened in 2023, running from Marina to Mile 2
Planned network of 7 lines to transform public transport across the city
Water and Sanitation Improvements
Lagos State Water Corporation working to expand piped water coverage
Adiyan Water Treatment Plant expansion to increase supply
Community toilet blocks built in slum areas by NGOs and government
However, progress is slow and demand continues to outstrip supply
Waste Management
Lagos State Waste Management Authority (LAWMA) manages collection and disposal
Olusosun landfill site (West Africa's largest) processes thousands of tonnes daily
Recycling initiatives including "Wecyclers" using cargo bicycles to collect recyclables
Private waste collectors (PSPs) complement government services in some areas
Exam Tip: When assessing urban planning, always evaluate whether strategies benefit ALL residents or just the wealthy. Eko Atlantic is often criticised for ignoring the needs of the 60% who live in slums. The best answers show understanding of inequality in urban planning.

✅ Answers
Lagos has grown rapidly due to rural-urban migration driven by push factors (poverty, Boko Haram insurgency, desertification in rural Nigeria) and pull factors (employment in oil and manufacturing, higher incomes, education and healthcare) (1 mark). Natural increase also contributes significantly - the young migrant population has high birth rates (36 per 1,000) and improved healthcare reduces death rates (1 mark). Lagos's economic importance (generating 25% of Nigeria's GDP) creates a cycle of growth as more jobs attract more migrants (1 mark). Net migration adds 500,000 people annually, while natural increase adds a similar number, giving a total growth rate of over 3% per year (1 mark).
In Lagos, water and sanitation is a major challenge - only 10% of residents have piped water and 60% lack adequate sanitation (1 mark). This leads to waterborne diseases like cholera, especially in slum areas like Makoko where open defecation contaminates water sources (1 mark). Traffic congestion is another challenge - over 5 million cars on limited roads create commutes of over 2 hours (1 mark). This costs the economy $8.5 billion per year and causes air pollution, stress and lost productivity (1 mark).
Lagos offers significant opportunities - it generates 25% of Nigeria's GDP, providing employment in oil, manufacturing, tech and services (1 mark). The informal economy supports 65% of workers through street trading and transport services (1 mark). However, challenges are severe - 60% live in slums with overcrowding and poor sanitation (1 mark). Traffic congestion costs $8.5 billion per year, and unemployment is estimated at 20-30% (1 mark). Urban planning attempts like the BRT system and Eko Atlantic address some issues but often benefit wealthier residents more than the poor majority (1 mark). The opportunities of economic growth and social mobility must be weighed against the reality of slum conditions and inadequate services for most residents (1 mark).
I agree that urban planning often benefits the wealthy more than the poor. Eko Atlantic is a prime example - a new city built on reclaimed land designed for 250,000-500,000 residents with modern infrastructure, reliable electricity and clean water (1 mark). However, the cost of living there excludes the 60% of Lagos residents who live in informal settlements, making it effectively a "city for the rich" (1 mark). When slums are demolished for development, poor residents are displaced without adequate alternatives (1 mark). The BRT transport system primarily benefits those commuting along major corridors, while slum residents in remote areas still rely on expensive informal transport (1 mark). However, some planning does benefit the poor - community toilet blocks in slums improve sanitation, and LAWMA's waste collection reduces disease (1 mark). The Lagos Light Rail could eventually improve access for lower-income commuters if fares are affordable (1 mark). The fundamental problem is that urban planning in LICs and NEEs is often underfunded and unable to keep pace with rapid population growth (1 mark). When resources are limited, they tend to flow to projects that generate revenue or attract investment, rather than to basic services for the poorest (1 mark). In conclusion, while some planning benefits reach the poor, the overall pattern in Lagos shows that wealthier residents gain disproportionately from urban development, perpetuating inequality (1 mark).

✍️ Model Answer
Full-Mark Response
6 marks: Explain the key factors affecting urban growth in lics and nees.
Urban Growth in LICs and NEEs involves multiple interconnected factors that geographers must understand. The key concepts include the processes that create and change urban growth in lics and nees, the impacts on both people and environment, and the strategies used to manage associated challenges. For a comprehensive answer, specific case study evidence should be used throughout, with named examples and data to support each point. Geographical terminology should be used precisely, and the interrelationship between physical and human factors should be demonstrated. Top-level responses evaluate the relative importance of different factors and consider how the situation varies between locations.
Mark scheme: 2 marks for identifying key factors, 2 marks for explaining processes with detail, 2 marks for using specific evidence
