Why do we need land? Food Shelter Natural resources

How do we use it? Agriculture Rangeland Recreation (national forest etc) Urbanization Mining Forest Waste disposal

How much land are we talking about? http://soil.gsfc.nasa.gov/index.php?section=70#app2 http://www.farmland.org/Flash/appleEarth.html

Federal and State Land Management

Land Use

Urbanization Definition: the use of land to build cities, businesses and homes. Problems: Urban Crisis: overwhelming the infrastructure. Urban sprawl: rapid expansion (Suburs Development with no marginal lands : NO WHERE TO GROW!!! Pollution: air, water (urban run-off) Lack of biodiversity https://www.youtube.com/watch?v=Ak-js9MPSMU

Solutions: Land use planning: GIS (Geographic information system) Mass transit Open space (Central park)

Now make the Connections Urban crisis Urban Sprawl Development on marginal land Pollution Lack of biodiversity Land –use planning Mass Transit Open space

Rangelands Definition: Grazing land Problems: Overgrazing Loss of biodiversity Soil erosion

Solutions: Public Rangelands Improvement ACT: gov’t rents out the land so they can keep regulations on use. Limit the number of livestock Fencing and field rotation

Make Connections Solutions Problems Public Rangeland improvement ACT Limit the number of livestock Fencing and field rotation Problems Overgrazing lack of biodiversity Soil Erosion

Forest Lands How we use it: paper, furniture, lumber, maple syrup, turpentine, CO2 Removal Problems: Clear cutting Deforestation: for agriculture, homes and roads) Loss of biodiversity Habitat loss erosion

Solutions: Selective cutting reforestation

Recreation Definition: fun stuff Problems Litter Traffic Atv’s Drilling, logging and urban areas too close so pollution gets in.

Solutions Education Buffer zones Stricter regulations

Drilling, logging and cities to close Make Connections Problems Litter Traffic ATV’s Drilling, logging and cities to close Solutions education Buffer zones Stricter regulations
