What would you be without Agriculture? Question:
4
Answer: Naked & Hungry
5
What is Agriculture? Agriculture: Activities concerned with the production of plants and animals, and related supplies, services, mechanics, products, processing, and marketing.
6
Agriculture defined USDA refers to agriculture as “ agriculture/agribusiness and renewable natural resources. ” food, fiber, and environmental systems www.usda.gov
7
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 Agriculture Progress
8
Fields of Agriculture Agronomy- The study of field crops.
9
Fields of Agriculture Horticulture involves the producing, processing & marketing of fruits, vegetables, and ornamental plants
10
Fields of Agriculture Animal Science- the study of the biology and management of domestic animals. This includes livestock, small animals and pets.
11
Fields of Agriculture Forestry- timber management for lumber, poles, post, plywood, etc.
12
Fields of Agriculture Biotechnology- manipulation of living organisms and organic material to serve human needs Improving plants or animals To get desirable traits Economic gain Increase production Etc…
13
Fields of Agriculture Soil Science- study of properties and management of soil.
14
Fields of Agriculture Aquaculture- growing and management of living things in the water.
15
Corn- #1 field crop produced & exported in America Corn production is more than 2 times that of any other crop Produced in every state in the U.S and on every continent except Antarctica!!! Common Field Crops
16
Corn Production
17
Corn – a zillion uses! Adhesives Aluminum Antibiotics Aspirin Babyfood Batteries Cereal Soda Gum Cosmetics crayons Diapers Leather Yogurt Wallpaper Toothpaste Syrup Tacos Soaps Cleaners Rugs Carpet Salad dressings Peanut butter Paper plates Mustard Ketchup Candy Mayonnaise Jelly Frozen food Instant coffee Malted products
18
Wheat Production
19
Specialized Agricultural Regions
20
Soybeans- the word’s most important source of vegetable oil. Good form of plant protein Provides the basic materials for many products. Ex: Crayons, shampoo, ink pens, Diesel Fuel, etc. Common Field Crops
21
Wheat- Important to survival of country. Contained in most bread products Cotton- “The fabric of our lives” Common Field Crops
22
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?
23
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).
24
While many people think that the “farmer” is becoming obsolete, this amount of population growth ensures that Agriculture will always be an essential industry.

Where Your Dollar Goes
28
What are we eating?? The average US citizen consumes yearly: 21.6 gallonsMilk 30.6 poundsCheese 64.9 poundsRed Meat 253.4Eggs 416.6 pounds Vegetables 194 poundsFlour and Cereal
29
What is produced on America’s Farms? Total Livestock, Dairy, and Eggs ~280,000,000,000 pounds Crops ~,900,000,000,000 pounds Corn ranks in the top five US exports every year
30
Farms Texas has the most farms The average farm size in the US is 500 acres 90% of farms are still family run
31
The projection is for the average size of farms in the US to Increase while the number Decreases trends
32
Commercial Agriculture in the U.S. Domination of agribusiness – vertical integration – capital & energy intensive – reliance on hybrid seeds / stocks
33
What the Farmer Looks Like
35
Trends Health concerns has caused an increase in consumption of poultry Why?
36
U.S. chicken consumption per capita has risen from 68.8 pounds in 1995 to an estimated 85.6 pounds today Poultry is generally cheaper per pound than other meat Healthier (leaner) Appeal to kids. (Beef nuggets, anyone?) Versatile – baked, fried, soup, nuggets, wings, etc…
37
Total acreage of farmland: 517,879 Average farm: 67 acres Total # of farms: 7,691 Farm #’s grew 27% between 2002-2007 Farmers markets: 202 Revenue: $6 billion! Massachusetts Agriculture 2007 farm census

42
Origins of Plant and Animal Domestication Rise of specialized agriculture & towns engaged in localized trading
43
Percent of Labor Force in Agriculture
44
Formal agricultural regions
46
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
47
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
48
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
49
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
50
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
51
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
53
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
54
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
55
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
56
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
57
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
58
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
59
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
