IB Geography Case Studies: A Comprehensive Exam Guide

Below are reliable, syllabus-friendly IB Geography case studies you can adapt to many common question styles. The goal is not to memorise paragraphs. The goal is to carry a small set of flexible examples into the exam.

Urban environments: London’s sustainable urban development

London works well for IB Geography because it is detailed, current, and full of trade-offs.

What to remember

• Transport: congestion charging, public transport investment, cycling infrastructure

• Housing: regeneration in East London, affordability tensions, sustainability targets

• Green space: parks, greening initiatives, urban liveability goals

How to use it in answers

• Link London to urban challenges like congestion, air quality, and inequality.

• Evaluate sustainability by asking: Who benefits, who pays, and what is displaced?

• Compare it with a contrasting city you know (even briefly) to elevate evaluation.

Population and migration: China’s One-Child Policy

This is a classic IB Geography case study because it shows how a single policy can reshape demographics for decades.

What to remember

• Introduced: 1979

• Aims: slow population growth to reduce pressure on services, economy, environment

• Outcomes: falling birth rates, ageing population, gender imbalance

• Policy shift: two-child policy (2016) and three-child policy (2021)

How to use it in answers

• Explain why population policies can create unintended consequences.

• Evaluate effectiveness using time scale: short-term success vs long-term demographic pressure.

• Bring in concepts like dependency ratio and workforce impacts for higher-level synthesis.

Hazards and disasters: the 2011 Tōhoku earthquake and tsunami

Tōhoku is powerful in IB Geography because it combines a major hazard event with cascading impacts.

What to remember

• Date: March 2011

• Magnitude: 9.0 earthquake plus tsunami

• Impacts: large loss of life, infrastructure damage, Fukushima nuclear crisis

• Responses: emergency response, international support, long-term reconstruction

How to use it in answers

• Separate hazard from disaster: physical trigger vs human vulnerability.

• Evaluate response using governance, preparedness, and recovery planning.

• Use it to discuss how even high-income states face limits when risk is extreme.

You can deepen hazard comparisons using RevisionDojo’s syllabus-aligned notes: D.3.1 Case Studies of Geophysical Hazards and reinforce details with the matching Geophysical Hazards Flashcards.

Global climate change: the Maldives and sea level rise

The Maldives is a compact IB Geography case study that makes vulnerability feel concrete.

What to remember

• Low-lying islands with high exposure to sea level rise

• Impacts: threats to tourism, infrastructure, livelihoods, habitability

• Responses: sea walls, adaptation planning, efforts to protect the economy

How to use it in answers

• Use it to distinguish mitigation vs adaptation.

• Evaluate fairness: those least responsible often face the highest risk.

• Scale it up: connect local impacts to global climate systems and policy debates.

Resource management: water management in Singapore

Singapore is a favourite IB Geography case study because it is strategy-driven and easy to structure.

What to remember

• Constraint: limited natural freshwater

• Strategies: desalination, recycled water, rainwater harvesting, public education

• Outcome: stronger water security and long-term planning

How to use it in answers

• Link to sustainability and resilience planning under scarcity.

• Evaluate trade-offs like energy costs, governance capacity, and equity.

• Compare with a water-insecure state to add depth.

How to turn IB Geography case studies into marks

Strong IB Geography answers are built, not hoped for. Here is the habit that changes everything: practise writing a case study in three layers.

• Layer 1 (10 seconds): name + context (“Tōhoku 2011, Japan; 9.0 quake and tsunami”)

• Layer 2 (30 seconds): two impacts + one response

• Layer 3 (60 seconds): evaluation (“effective early warning, but cascading nuclear risk exposed limits”)

Then stress-test your IB Geography case studies using exam-style prompts. RevisionDojo’s Questionbank and AI Chat help you generate targeted questions, while Grading tools and Mock Exams help you spot if you are describing too much and evaluating too little. When you need quick retrieval, build a small deck in Flashcards. When you need structure, lean on Study Notes. And if you want human feedback, RevisionDojo Tutors can help you sharpen how you deploy each IB Geography case study.

FAQ: IB Geography case studies for exams

How many IB Geography case studies should I learn?

Most students do better with fewer, deeper IB Geography case studies. Aim for a core set that covers your likely themes and can be adapted across questions. For each theme, having one strong case study plus a lighter backup gives you flexibility without overload. Depth matters because evaluation requires specifics: stakeholders, time scale, limitations, and trade-offs. If you are HL, you may need a slightly wider spread, but the principle stays the same. Use the RevisionDojo Questionbank to identify recurring question patterns, then map each pattern to a case study you already know. That way your IB Geography revision is driven by exam demand, not by panic.

What makes an IB Geography case study “high scoring”?

A high-scoring IB Geography case study is not a long story; it is a well-aimed tool. It includes a clear context, a few defensible facts, and an obvious link to the command term in the question. It also contains an evaluation angle you can reach quickly: winners and losers, short vs long term, or local vs national effects. Examiners notice when you select evidence that matches the question rather than dumping everything you remember. Your job is to make the case study serve the argument. Practise writing one evaluation sentence for each case study and you will feel the difference immediately.

How do I revise IB Geography case studies without forgetting them?

Treat each IB Geography case study like a small set of “retrieval hooks.” Start with a one-page summary or a tight flashcard set: location, dates, two stats, impacts, responses, evaluation. Then revise by active recall, not rereading: cover your notes and reconstruct them from memory. Next, apply the case study in mini-plans to different question styles so the knowledge becomes flexible. This is where RevisionDojo’s Flashcards and AI Chat work well: you can quiz yourself, then ask for variations of prompts that force transfer. Finally, do short timed paragraphs in Mock Exams so recall happens under pressure, not just at your desk. Over time, your IB Geography case studies become automatic.

The final step: make your IB Geography case studies usable

Your exam is not a memory contest. It is a decision-making contest: picking the right evidence, placing it at the right moment, and evaluating it like a geographer.

If you want your IB Geography case studies to feel lighter and more reliable, build them once in RevisionDojo and then practise them repeatedly across Questionbank prompts, Study Notes, Flashcards, AI Chat, Grading tools, and Mock Exams. When you do that, the case study stops being a paragraph you are trying to remember and becomes an advantage you can use on purpose.
