Section 1: How We Use Land

2. Land Use and Land Cover Purposes for Land: Farming Mining
Building Cities and Highways
Recreation
Land Cover: What your find on a patch of land. (How it is used depends on what is on it)

3. Land Use and Land Cover Types of Land Cover Forest Field of Grain
Parking Lot

4. **Most land provides one or more resources used by humans.

5. Urban Land vs. Rural Land
Urban Land: land that is covered mainly with buildings and roads.
**U.S. Census Bureau: Urban areas contain 2,500 or more people and have a governing body (city council)
Rural Land: Land that contains relatively few people and large areas of open space.

6. **Relative proportion of each of the types of land cover.

7. Where We Live Until about 1850, most people lived in rural areas.
Occupations of those people:
Farmers: grew crops and raised livestock.
Forest Managers
Miners
Mill workers
Manufacturers of goods for town
**What changed this pattern??

8. From Farms to Factories
Industrial Revolution Changed Lifestyles
Machinery made it possible for fewer people to operate a farm or grain mill.
Better transportation allowed manufacturers to live far from costumers.
People moved to cities to find jobs.

9. Result of Industrial Revolution
Urban areas grew rapidly during 20th century.
Urban areas spread over more land.
: movement of people from rural areas to urban areas happened quickly in developed countries.

11. The Urban-Rural Connection
People are dependent on resources produced in rural areas.
Clean drinking water
Fertile soil
Land for crops
Trees for wood and paper
Oxygen
Ecosystem Services: resources produced by natural and artificial ecosystems.

13. Supporting Urban Areas
The area of rural land needed to support one person depends on many factors:
Climate
Standard of living
How effeciently resources are used

14. Example: In a wet climate, most agriculture depends on rain and does not depend on areas of lakes and rivers for irrigation.

15. Developed Countries: each person uses the ecosystem services provided by about 8 hectares (20 acres) of land and water.
US: each person uses 12 hectares (30 acres)
Germany: 6 hectares (15 acres)
Developing Countries: people may not have access to all the resources for a healthy life. They may use less than 1 hectare (2.5) per person.
