Urban areas and management
Explain urban growth and changing land use, interpret city structures and assess the trade-offs in sustainable urban management.
Exam scope and assessment notes
Cambridge International AS & A Level Geography 9696, 2027–2029 syllabus, Topic 6. Across every topic, practise reading both quantitative and qualitative geographical resources, describing patterns before explaining them, evaluating evidence and producing a structured, supported conclusion. These original explanations and self-checks are independent study support, not Cambridge questions, official marks or grades. Centre-selected named examples and detailed case studies still need course-specific evidence packs. Full timed mock papers, official marking or grade prediction, and human subject-teacher review are not provided. Fieldwork is not assessed in this syllabus, but this site does not collect or supervise primary data.
Before you begin
- Cambridge recommends prior Geography at approximately Cambridge IGCSE or Cambridge O Level. Read the source and its scale before explaining patterns; support evaluation with relevant evidence.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which process describes population and activities moving back into a city after decline?
What you will learn
- Compare urbanisation, suburbanisation, sprawl, counter-urbanisation and regeneration
- Analyse urban hierarchy, place identity and changing land-use patterns
- Assess sustainability across environmental, social, economic and political priorities
- Evaluate strategies for transport, waste, housing and green space using a named urban area
Urban growth changes places and relationships between places
Urban growth can mean an increase in population, built-up area or both. Urbanisation, suburbanisation, urban sprawl, counter-urbanisation, re-urbanisation, renewal and regeneration describe different processes. Causes may include social, economic, political and historical factors; consequences can affect both urban and rural areas.
A settlement hierarchy ranks urban places by size or function. A primate city is disproportionately large or influential within its country; world cities are grouped by their global roles and connections. These categories require evidence and a stated scale, not only a city label.
Urban form and activities change over time
Physical setting, land prices, transport, investment, planning and history influence horizontal and vertical structure and land-use zones. Place identity and perception differ among residents, visitors, businesses and planners. Retail, manufacturing, services, the CBD and housing can shift as populations and competition for space change.
Residential zones vary with income, housing supply, ethnicity, planning, culture and history. A map shows a pattern, not its cause: combine map evidence, statistics and local accounts, and recognize that cities can change at different rates.
Sustainability requires balancing different priorities
Urban sustainability is difficult to measure because environmental, social, economic and political priorities can conflict. Residents, landowners, businesses, community groups and governments may value different outcomes. Solid-waste disposal, public and private transport, housing quality and density, green space and water features are connected issues.
Strategies may include waste reduction and recycling, cleaner transport, housing improvement, green infrastructure and water-sensitive design. Judge constraints and incentives, who pays and benefits, access, maintenance and unintended effects. Use a named urban-area example selected for your course; a generic city is not a substitute for verified case evidence.

Pause and explain
Why should an urban sustainability assessment include different groups of people?
Worked example
A city expands its rail network while redeveloping nearby housing. Give one potential sustainability benefit, one trade-off and the evidence needed to evaluate the scheme.
Show the worked solution
- Rail may reduce reliance on private cars and improve access for some residents.
- Redevelopment may raise housing costs or displace existing communities; construction also uses resources.
- Compare travel mode, air quality, housing affordability, access by group and before/after trends against a suitable baseline.
Answer The scheme could improve access and reduce transport emissions but might worsen affordability or displacement. Evaluate these outcomes with disaggregated local evidence and a clear comparison period.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A city has 2.4 million people in 2020 and 2.76 million in 2030. Calculate percentage growth and state why it does not show urban sprawl by itself.
Give me a hint
Use the 2020 population as the base; distinguish population growth from change in built-up area.
Compare my reasoning
- Increase = 2.76 − 2.4 = 0.36 million.
- Percentage growth = 0.36 ÷ 2.4 × 100 = 15%.
- Sprawl concerns outward land expansion; compare built-up area, density and settlement form.
Population rose by 15%. This does not establish sprawl because urban land area and density are also needed.
Look for these in your work
- Correct change
- Correct base
- Population and area distinguished
A new retail centre opens on the urban edge, while the CBD loses shops. Explain two factors that may cause this shift and name evidence to test your explanation.
Give me a hint
Consider accessibility, land costs, planning and competition between locations.
Compare my reasoning
- New roads or public transport may make the edge more accessible to some shoppers.
- Lower land costs or planning permission may attract large stores, while online retail or changing preferences can affect the CBD.
- Use land-use maps, vacancy rates, rents, travel data and interviews over time; do not infer causation from one map.
Accessibility, costs, planning and changing retail habits may interact. Time-series and user evidence would help separate their roles.
Look for these in your work
- Two plausible factors explained
- Evidence matched to claims
- Causal uncertainty retained
Evaluate a city plan that promotes higher-density housing, public transport and green space to improve sustainability.
Give me a hint
Assess all four dimensions and consider distribution, feasibility and unintended effects.
Compare my reasoning
- Higher density may support transit and reduce land take, but housing quality and affordability must be protected.
- Public transport can improve access and reduce car use if routes, fares and service frequency suit different groups.
- Green space supports recreation and heat management but needs land, maintenance and fair access; judge outcomes using local social, economic, environmental and governance evidence.
The plan may improve sustainability if housing remains healthy and affordable, transit is reliable and green space is accessible. Its success depends on delivery, funding, maintenance and who benefits.
Look for these in your work
- All strategies assessed
- Multiple sustainability dimensions
- Conditional, evidence-led judgement
Common mistakes
- Using urbanisation to mean any increase in a city's built-up area
- Calling every large city a primate city or world city without comparison
- Treating land-use patterns as proof of one cause
- Measuring sustainability only through environmental indicators
- Claiming regeneration benefits all residents equally
What can you explain now?
What additional evidence would help explain a residential land-use pattern on a map?
Compare with the explanation
Evidence about housing, income, planning, transport and residents' experiences
A pattern must be connected to relevant physical and human factors before it is explained.

Make it stick
Name three processes of urban growth and explain why a sustainability plan must consider both place-based evidence and different groups.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
