2% of America’s work force produces the food and fiber to meet the needs of our nation
There has been a reduction from 90% of the nation’ population involved in farming 200 years ago

World Outlook The worlds population is continually
expanding. More children are surviving to
adulthood.Adults are living longer.
What impact will this have on our resources?
![Page 22: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/22.jpg)
World Outlook Population growth will:
1. Add stress to environmental systems of air, water, soil, and natural resources.
2. Create challenges to meet the demands for food and fiber (clothing and shelter).
![Page 23: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/23.jpg)
While many people think that the “farmer” is becoming obsolete, this amount of population growth ensures that Agriculture will always be an essential industry.

Agricultural diffusion
The origin and diffusion of plant domestication Agriculture apparently began with plant
domestication Domesticated plant—one deliberately planted,
protected, and cared for by humans Genetically distinct from wild ancestors
because of deliberate improvement through selective breeding
Tend to be larger than wild species, bearing larger, more abundant crops
For example—wild Indian maize grew on a cob only 0.75 inches long
![Page 46: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/46.jpg)
Agricultural diffusion
Plant domestication and improvement constituted a process, not an event Began because of close association
between humans and natural vegetation over a period of hundreds or even thousands of years
Useful plants were protected by humans, which led to deliberate planting
![Page 47: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/47.jpg)
Agricultural diffusion
The origin and diffusion of animal domestication
Domesticated animal—one dependent on people for food and shelter Differs from wild species in physical appearance
and behavior Result of controlled breeding and daily contact
with humans Apparently occurred later (with the exception
of the dog) than did the first planting of crops People may have first domesticated cattle and
some birds for religious reasons
![Page 48: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/48.jpg)
Agricultural diffusion
The pig and the dog may have attached themselves to human settlements to feast on garbage
Farmers of the southern Asian crop hearth and American Indians did not excel at animal domestication Asians did have some poultry American Indians had the llama,
alpaca, guinea pig, and the turkey
![Page 49: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/49.jpg)
Agricultural diffusion
The beginning of nomadic herding As grain-herd livestock farming expanded
tillers entered marginal lands Crop cultivation proved difficult or impossible Population pressures forced people into
marginal areas Livestock became more important than crops People began wandering with their herds so
as not to exhaust local forage
![Page 50: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/50.jpg)
Commercial livestock fattening Farmers raise and fatten cattle and hogs for
slaughter One of the most developed fattening areas is
the Corn Belt of the Midwestern United States—Farmers raise maize and soybeans as feed
In Europe, feed crops are more commonly oats and potatoes
Smaller zones of commercial livestock fattening also appears in southern Brazil and South Africa
Crop and animal raising is combined on the same farm
![Page 51: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/51.jpg)

Commercial livestock fattening
Some geographers call this type of agriculture: mixed crop and livestock farming
Specialization Farmers breed many of the animals they
fatten, especially hogs Other farmers concentrate on preparing cattle
and hogs for market In factory-like feedlots, farmers raise imported
cattle and hogs on purchased feed Such feedlots are most common in the
western and southern United States
![Page 53: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/53.jpg)
Commercial livestock fattening
The question of feedlot nutritional efficiency In the 1900s world grain production rose
much faster than did world population growth
Cereals provide most of the protein intake of the world’s people
At least one-half of America’s harvested agricultural land is planted with feed crops for livestock
Over 70 percent of America’s grain crop is used to feed livestock
![Page 54: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/54.jpg)
Commercial livestock fattening
The question of feedlot nutritional efficiency A cow must eat 21 pounds of grain to
produce one pound of edible protein Protein lost through conversion from plant to
meat could make up almost all the world’s present protein deficiency
Today, food that feeds Americans would feed 1.5 billion at the consumption level of China
Poorer countries such as Costa Rica and Brazil are destroying rain forests to fatten beef for America’s fast-food restaurants

Livestock ranching Raise only cattle and sheep in large numbers Where ranchers specialize in cattle raising
United States and Canada Tropical and subtropical Latin America, and
warmer parts of Australia Mid-latitude ranchers in the Southern Hemisphere
specialize in sheep Australia, New Zealand, South Africa, and Argentina
produce 70 percent of world’s export wool Sheep outnumber people 8 to 1 in Australia, and 16
to 1 in New Zealand

Urban Agriculture
Practiced by migrants to cities in developing countries
Consist of tiny plots of land Can produce enough to feed a family—
vegetables, fruit, meat, and milk May produce a surplus to sell
![Page 57: Food for thought What would you be without Agriculture? Question:](https://reader035.vdocument.in/reader035/viewer/2022062523/5a4d1acf7f8b9ab059970f13/html5/thumbnails/57.jpg)
Urban Agriculture
In China now provides 90 percent or more of all vegetables consumed in cities
Nairobi and Kampala, Africa produce 20 percent of food from city lands
Many inhabitants of Sarajevo in Bosnia survived conflict because of urban agriculture
Cities in Russia derive much food from urban agriculture

Sustainable Agriculture Alternatives to monoculture, and heavy
use of pesticides and energy inputs Such as programs of social, ecological,
and economic health for agricultural land and communities
Options include: organic farming, agroecology, holistic management, urban gardening, community-supported agriculture, natural systems agriculture
Reliance on local knowledge & minimization of ecological impacts
