🎯 Exam Connection

Frequency: This topic appears in almost every recent sitting. Megacity challenges, rural-urban migration, and case study comparisons are among the most reliably examined topics in GCSE Geography (AQA, OCR, Edexcel).

Typical question stems you will see:

  • "Describe the push and pull factors that cause rural-urban migration." (4 marks)
  • "Explain why megacities face challenges." (6 marks)
  • "Using a named city in an LIC or NEE, explain the causes and consequences of rapid urban growth." (6 marks)
  • "Evaluate the effectiveness of strategies to manage urban challenges in LICs/NEEs." (8 marks)
  • "To what extent do top-down strategies provide the best solution to the challenges of megacity growth?" (8–9 marks)

What Level 1, 2, and 3 look like — for an 8-mark evaluate question:

Level 1 (1–3 marks): "Megacities face challenges because lots of people move there. There is not enough housing for everyone and traffic is very bad. Cities should build more houses."
What's missing: no case study evidence, no named examples, no explanation of why the challenge exists, no evaluation
Level 2 (4–6 marks): "Megacities in LICs/NEEs grow rapidly because of rural-urban migration driven by push factors like mechanisation of farming and pull factors like higher wages — urban workers earn 3–5× more than rural workers. This causes housing shortages — in Dhaka, 40% of residents live in informal settlements (bastis) with poor sanitation and flood risk. Top-down solutions like ADB flood embankments have helped but do not reach all residents."
What's here: named evidence, push/pull framework, case study, one solution — but no evaluation of why solutions succeed or fail
Level 3 (7–8 marks): "The rapid growth of megacities in LICs/NEEs is driven by compound push-pull migration — mechanisation removes rural livelihoods while urban wages can be 3–5× higher, and climate change-induced flooding (Bangladesh's 70% below 6m) is increasingly pushing climate migrants to Dhaka, adding 300,000 people per year. This creates compounding challenges: Dhaka generates 35,000 tonnes of waste daily with no formal collection in bastis, and its 7 km/h average traffic speed costs Bangladesh 3% of GDP annually. Top-down solutions like ADB embankments protect formal areas but miss the 40% in bastis. Bottom-up approaches like BRAC have reached 100 million people more efficiently, but cannot replace flood defences or metro systems. The most effective strategy — as Rio's Favela-Bairro demonstrates — combines government funding with community agency, upgrading communities rather than demolishing them. However, in Dhaka's specific context of extreme poverty (GNI $2,800) and climate exposure, no single approach is sufficient: the city needs both immediate community-level intervention and long-term international investment in climate-resilient infrastructure."
What makes this Level 3: named statistics throughout, two case studies (Dhaka and Rio), evaluation of both approaches with a reasoned judgement, acknowledgement of context-specific constraints

Command word guidance:

  • Describe: State what you can observe — name the pattern, trend, or feature. Use data. Do not explain why.
  • Explain: Give reasons. Use "because", "this means that", "as a result". Link causes to consequences.
  • Evaluate / "to what extent": Weigh up evidence on both sides, consider different viewpoints or contexts, and reach a supported judgement. Do not just list evidence — judge it.
  • Using a named example: This instruction in the question means you MUST name a specific city and deploy specific data. A vague reference to "a city in Asia" will not access Level 2 marks.
