What this set covers
City problems and the ideas for managing them run through this set. The urban heat island, photochemical smog, temperature inversion, congestion charges, bus rapid transit, green belts, segregation, gated communities, eco-cities, smart cities and compact cities appear.
- Common mix-up
- Students often mix up an eco-city and a smart city: an eco-city is planned around renewable energy and low waste, while a smart city uses sensors and data to run services.
- Revision tip
- For one city you know, pair each stress in this set with a response, and say whether that response is a policy, a design or a technology.
