Do Now What are examples of private (individual) and public (collective) ownership of land and other objects?
3
Land Use Management in USA
4
Land Use Agencies Read the handout your group has been given. Take notes on the responsibilities of the agency. You will be presenting that information to the class. Question to think about: How might the goals of each agency conflict with others?
5
A Guide to Your National Forests Look at the information on the handout. Answer the following questions: What does the Forest Service do? How are National Forests used?
6
Some important definitions: Multiple Use: Use of land for more than one purpose Example: Allowing both hiking and logging in National Forests Sustained Yield: Limited use/production of a resource that allows that resource to be replenished instead of depleted Example: Limiting the number of trees that can be removed from a forest in a certain time period Renewable Resource: any resource that can be replenished naturally with the passage of time. Examples: Wood, solar energy, water Stewardship: the overseeing and protection of something considered worth caring for and preserving Example: Protecting an endangered species from going extinct
7
Land Use on Public Lands In your groups, create a list of the activities and land uses permissible on public lands categorize items under “recreational” and “commercial” How does each of these activities impact the other? Complete the matrix with a partner.
8
School Survey Walk around the school campus. Map land uses on campus and document potential problems and conflicts. Think about the following questions: How has the physical environment been altered to accommodate human uses? Who makes decisions about how the space is used? What individuals or groups influence decisions about land uses and activities? Are there conflicts evident? How can they be resolved to the satisfaction of all?
9
How Humans Use Land Rangeland: for grazing food animals Forest Land: harvesting wood, wildlife, fish Cropland: land for growing plants Parks and Preserves: Recreation and preserving wilderness and wildlife Wetlands, mountains, deserts: difficult for humans to use Urban Land: used for houses, businesses, roads, and other.
10
Rangeland Very important for food supply Urban development is threatening farmland and grassland Overgrazing: allowing animals to graze more than the land can take Sustaining rangeland: Limiting herd sizes Allow recovery time in between uses Managed by Department of Agriculture
11
Forests On average, people in the USA use 3.5 times more wood than other people around the world Harvesting trees: Clear CuttingSelective Cutting Deforestation: Deforestation: Clearing trees without replacing them
12
Cropland USA has over 200 million acres of cropland Urban development is taking over agricultural lands Bad farming practices cause land to degrade: Case Study: The Dust Bowl Case Study: The Dust Bowl What did the farmers do to cause this? What natural event made it worse? What helped us come out of the dust bowl?
13
Urbanization People moving from rural areas (country) to cities Problems in Cities: traffic jams, increased poverty, and polluted air and water Problems Around Cities: Urban sprawl: Rapid expansion of the city into the country Development on land prone to landslides or flooding Heat Islands: hotter temps in cities because of concrete and glass
14
Heat Island Lab The buildings, concrete, asphalt, and glass of cities can cause them to be up to 10 degrees warmer than natural areas. Your pair will be assigned an area around the school to measure. Take your thermometer out to this area and hold it at waist height for 4 minutes. Record the final temperature, and bring it back to the classroom. Does our school seem to have a heat island effect?
