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)

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

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

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.

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

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??

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.

Result of Industrial Revolution Urban areas grew rapidly during 20th century. Urban areas spread over more land. 1880-1950: movement of people from rural areas to urban areas happened quickly in developed countries.

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.

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

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

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.
