This final lesson brings together everything you have studied in Topic 3: Challenges of an Urbanising World. It provides a comprehensive key terms glossary, comparison tables for quick revision, a revision checklist to identify any gaps in your knowledge, and detailed guidance on exam technique for the types of questions you will face in the Edexcel B Paper 1 exam. Use this lesson as your revision hub in the weeks before the exam.

| Natural increase | Population growth from births exceeding deaths (without migration) |
| Counter-urbanisation | Movement of people from urban areas to rural or semi-rural areas |
| Suburbanisation | The outward spread of the built-up area as population moves to the urban edge |
| Re-urbanisation | Movement of people back into city centres after a period of decline |

| Rate of urbanisation | Slow or stable | Fast (1.5–5%/year) |
| Main driver | Historical industrialisation (now complete) | Current rural-to-urban migration + natural increase |
| Housing challenge | Affordability; homelessness | Informal settlements; lack of basic services |
| Transport | Well-developed but congested | Inadequate and overwhelmed |
| Key process | Counter-urbanisation; re-urbanisation | Rapid rural-to-urban migration |
| Waste management | Organised collection; recycling targets | Inadequate; informal recycling dominant |
| Planning | Established legal frameworks | Weak enforcement; unable to keep pace |
| Opportunities | Challenges |
|---|---|
| Diverse economy: finance, IT, Bollywood, textiles | Housing: 1.1m unit deficit; 60% in slums |
| BSE and NSE stock exchanges | Water: 750 MLD shortfall; 4–6 hrs/day supply |
| 6% of India's GDP | Sanitation: ~40% sewage untreated |
| IIT Bombay; 90% literacy | Transport: 7.5m rail users/day; 2,500 deaths/year |
| World-class hospitals; medical tourism | Air pollution: PM2.5 35–45 µg/m³ |
| Cultural diversity; social mobility | Inequality: extreme wealth alongside extreme poverty |
| Feature | Freiburg (Germany) | BedZED (London) | Curitiba (Brazil) |
|---|---|---|---|
| Country type | HIC | HIC | NEE |
| Key focus | Solar energy; car-free living; cycling | Zero-energy housing; water conservation | Sustainable transport (BRT); recycling |
| Scale | City-wide (230,000 people) + Vauban district | Small development (100 homes) | City-wide (1.9 million) |
| Transport | 30% cycling; extensive tram network | Car-sharing club; public transport | BRT: 2 million trips/day; cost 1/100th of metro |
| Energy | Passivhaus; plus-energy houses; rooftop solar | Super-insulation; CHP plant; solar panels | Focus on transport efficiency rather than energy |
| Waste | 69% recycling rate | Reduced waste generation | 70% recycling; Cambio Verde (green exchange) |
| Key statistic | 70% of Vauban households car-free | 71% less heating energy than UK average | BRT carries 2 million trips daily |
| Feature | Top-Down | Bottom-Up |
|---|---|---|
| Decision-making | Government or large organisations | Local communities and residents |
| Scale | Large; city-wide or national | Small; neighbourhood or community level |
| Cost | High (often billions) | Low (often thousands to millions) |
| Speed of impact | Slow (planning, construction, bureaucracy) | Faster at local level |
| Sustainability | Risk of white elephant projects; maintenance challenges | Often more sustainable because community owns the solution |
| Mumbai examples | DRP ($3–4bn); Metro (337 km); MTHL bridge | SPARC community toilets; waste picker cooperatives; Versova beach clean-up |
| UK examples | London Olympic Park; HS2; Northern Powerhouse | Neighbourhood Plans; community land trusts; local clean-up groups |

Exam Tip: Go through this checklist honestly. For any row where you are NOT confident, go back to the relevant lesson and revise that topic. The exam can ask about any part of the specification, so gaps in knowledge are risky.
Topic 3: Challenges of an Urbanising World appears in Paper 1 of the Edexcel B GCSE Geography exam. The paper includes:
| Command Word | What It Means | Marks (Typical) |
|---|---|---|
| Define | Give the precise meaning of a term | 1 |
| State / Name / Identify | Give a brief factual answer | 1 |
| Describe | Give an account of what something is like — characteristics, features, patterns | 2–4 |
| Explain | Give reasons why something happens — use connective language (because, this means that, as a result) | 4–6 |
| Compare | Identify similarities AND differences between two things | 4–6 |
| Evaluate / Assess / Discuss | Weigh up both sides of an argument; consider strengths and weaknesses; reach a supported conclusion | 8–12 |
