Chapter 22:  Urbanization and Sustainability


Section 1:  What are the Major Population Trends in Urban Areas?

​Concept 22-1:  ​Urbanization continues to increase steadily, and the numbers and sizes of urban areas are growing rapidly, especially in less-developed countries.

Section 2:  What are the Major Urban Resource and Environmental Problems?

Concept 22-2:
 Most cities are unsustainable because of high levels of resource use, waste, pollution, and poverty.


Section 3:  How Does Transportation Affect Urban Environmental Impacts?

Concept 22-3:
 In some countries, many people live in widely dispersed urban areas and depend mostly on motor vehicles for their transportation, which greatly expands their ecological footprints.

Section 4:  How Important is Urban Land-Use Planning?

Concept 22-4:
 Urban land-use planning can help to reduce uncontrolled sprawl and slow the resulting degradation of air, water, land, biodiversity, and other natural resources.


Section 5:  How Can Cities Become More Sustainable and Livable?

Concept 22-5:
 An eco-city allows people to choose walking, biking, or gas transit for most transportation needs;  to recycle or reuse most of their wastes;  to grow much of their food;  and to protect biodiversity by preserving surrounding land.
