Chapter 14-1 How We Use Land 3/08

Where does our food come from?

Land Use Land use is what we do with a piece of land Land cover is what you find on a patch of land There are different uses for each cover type

Rangeland

Forest Land

Cropland

Parks and Preserves

Wetlands, Mountains, Deserts etc..

Urban Land

Where we Live Habitation patterns changed with the Industrial Revolution

Until 1850 Most people in the US lived in rural areas

Machinery and Fossil fuels resulted in fewer people being needed to raise food Movement from rural to urban is now happening in developing countries

Ecosystem Services Resources produced by natural or artificial ecosystems

Clean Drinking Water

Fertile Soil

Farmland

Trees for wood, paper, oxygen

How much rural land do we need? Developed Country requires about 8 hectares (20 acres) In US this figure is 12 hectares (30 acres)

Is it a good idea to replace valley farmland with houses?
