Urban Challenges & Sustainability - Complete Interactive Lesson
Part 1: Core Concepts
🌍 Urban Challenges & Sustainability
Part 1 of 7 — Problems of Rapid Urbanization
Challenges in the Developing World
| Challenge | Description | Example |
|---|---|---|
| Squatter settlements | Informal housing built on land without permission | Favelas (Brazil), slums (Mumbai) |
| Inadequate infrastructure | Lack of clean water, sanitation, electricity | ~1 billion people in slums worldwide |
| Traffic congestion | Rapid growth outpaces transportation planning | Jakarta, Cairo, Lagos |
| Air/water pollution | Industrial and vehicle emissions, untreated sewage | Delhi air quality, Ganges River pollution |
| Urban sprawl | Unplanned expansion consuming agricultural land | Peri-urban growth around African cities |
🔑 Squatter settlements (also called informal settlements or shanty towns) are NOT always negative — they often develop their own economies, social networks, and infrastructure over time.
Challenges in the Developed World
| Challenge | Description | Example |
|---|---|---|
| Suburban sprawl | Low-density, car-dependent development | American Sun Belt cities (Phoenix, Houston) |
| Inner-city decay | Loss of industry, jobs, and population from city centers | Detroit, Cleveland (deindustrialization) |
| Gentrification | Displacement of lower-income residents by affluent newcomers | Brooklyn, San Francisco |
| Brownfields | Contaminated former industrial sites | Rust Belt factory sites |
| Housing affordability | Rising costs excluding lower-income residents | San Francisco, London, Sydney |

Urban Sustainability Initiatives
| Strategy | How It Works | Example |
|---|---|---|
| Smart growth | Compact, walkable, mixed-use development | Portland, Oregon urban growth boundary |
| New Urbanism | Designing walkable neighborhoods with diverse housing | Seaside, Florida; Celebration, Florida |
| Greenbelts | Protected open space around cities limiting sprawl | London Green Belt (established 1947) |
| Transit-oriented development | Building dense housing near public transit stations | Curitiba, Brazil BRT system |
| Mixed-use zoning | Combining residential, commercial, and retail in one area | Many European city centers |
Measuring Urban Sustainability
- Ecological footprint: How much land/resources a city population requires
- Urban heat island effect: Cities are warmer than surrounding rural areas due to concrete, asphalt, reduced vegetation
- Brownfield redevelopment: Converting contaminated industrial sites to new uses
Applied Recall ✍️
-
Protected open space around a city designed to limit sprawl is called a _______.
-
The phenomenon where cities are warmer than surrounding rural areas is the urban _______ island effect.
-
Compact, walkable, mixed-use urban planning is called _______ growth.

AP Exam Strategy: Urban Geography
When analyzing urban challenges on the AP exam:
- Identify whether the city is in a developing or developed country — challenges differ significantly
- Connect challenges to urbanization causes — rapid rural-to-urban migration drives informal settlements
- Know the models — be ready to apply Burgess, Hoyt, Harris-Ullman, Griffin-Ford, or De Blij
- Solutions require trade-offs — gentrification improves neighborhoods but displaces residents
- Use specific examples — name real cities (Mumbai, Lagos, Detroit, Portland) in FRQ answers
