3. Agriculture
Agriculture – the purposeful tending of crops and raising of livestock in order to produce food and fiber.

4. Farm Facts • 2.2 million farms dot America’s rural landscape.
Farm and ranch families – 2%
15% - process and sell the nation’s food and fiber.
• In 2010, $115 billion agricultural products were exported
• Farmers and ranchers receive only 16 cents out of every dollar spent on food. The rest goes for costs beyond the farm gate: wages, production, processing, marketing, transportation and distribution.

5. Agriculture in Developed Countries
Mixed crop and livestock farming
Dairy farming
Grain farming
Livestock ranching
Mediterranean agriculture
Commercial gardening and fruit farming
Access to markets- Most is land extensive and capital intensive

6. Wheat Farm in Montana
American grain farms can cover enormous amounts of land.

7. World Milk Production, 2005
Fig 10-8: Milk production reflects wealth, culture, and environment. It is usually high in MDCs, especially production per capita, and varies considerably in LDCs.

8. Combines on Wheat in Kansas
Combines can reap, thresh, and clean crops like wheat in a single operation.

9. Agriculture in Less Developed Countries
Extensive Subsistence
Shifting cultivation
Pastoral nomadism
Plantation Farming
Intensive subsistence agriculture
Rice paddy
Market gardening

10. Shifting Cultivation in Guatemala
Dense vegetation has been cut and is being burned to open land for farming.

11. Pastoral Nomads in Iran
Qashqai nomads using paved roads to move their animals near Shiraz, Iran.

12. Wet Rice Terraces in Indonesia
Terraces create flat land for wet (irrigated) rice on hilly land in Indonesia.

13. Percent Arable by Country
Arable Land
Percent Arable by Country
Does the percent of land that is arable in a country determine the agricultural output or the calorie consumption in a country?

14. Challenges of New Way of Life
First Agricultural Revolution 12 thousand years ago!
Agriculture transformed way of life; exploited relatively small area of land intensively for given period of time (image of Ban Po, China)
Challenges of New Way of Life
Dependency of fewer crops
Greater vulnerability to weather
Dependency on harvest time
Need for intense physical labor 14

15. World Areas of Agricultural Innovations
Carl Sauer identified 11 areas where agricultural innovations occurred.

16. Vegetative Planting Hearths
Fig. 10-1: There were several main heaths, or centers of origin, for vegetative crops (roots & tubers, etc.), from which the crops diffused to other areas. Carl Sauer suggested that Southeast Asia was a primary hearth.

17. Seed Agriculture Hearths
Fig. 10-2: Seed agriculture also originated in several hearths and diffused from those elsewhere.

18. Animal Domestication – Yay! Dogs!
- Relatively few animals have been domesticated
- Attempts at domestication continue, but most fail

19. World Regions of Primarily Subsistence Agriculture
On this map, India and China are not shaded because farmers sell some produce at markets; in equatorial Africa and South America, subsistence farming allows little excess and thus little produce sold at markets.

20. Second Agriculture Revolution
Middle Ages through Industrial Revolution; major population explosion
A series of innovations, improvements, and techniques used to improve the output of agricultural surpluses (started before the industrial revolution).
eg. seed drill
advances in livestock breeding
new fertilizers

21. “The Isolated State” 1 – highly perishable; dairy, fruit
Von Thünen Model (1828)
Spatial economics: location and land rent important are connected
What farmers produce varies by distance from the town, with livestock raising farthest from town. Maximize profit.
Concentric rings where crops dominate, transportation is a key factor
1 – highly perishable; dairy, fruit
2 – forest (fuel & building material)
3 – less perishable; field crops, grains
4 – livestock, ranching (self-transporting)
“The Isolated State” 21

22. Von Thünen Model
Von Thünen’s model shows how distance from a city or market affects the
choice of agricultural activity in (a) a uniform landscape and (b) one with a
river.

23. Von Thunen Model in China
Lee Liu studied the spatial pattern of agriculture Found:
farmers living in a village farm both lands close to the village and far away intensively (conventional theory overlooks labor issues)
Distance from labor was more important than market or land rent
methods varied spatially – resulting in land improvement (by adding organic material) close to village and land degradation (lots of pesticides and fewer conservation tactics) farther from village.

24. Third Agriculture Revolution (Green Revolution)
New techniques, irrigation, fertilizers, grains and land ownership with the purpose of eliminating hunger
- increased production of rice
- new varieties in wheat and corn
- reduced famines due to crop failure,
now most famines are due to political problems
- impact (in terms of hunger) is greatest
where rice is produced

25. Average Daily Calorie Consumption per Capita

26. Opposition to Green Revolution
Opposition argues Green Revolution
has led to:
vulnerability to pests
Soil erosion
Water shortages
Micronutrient deficiencies
Dependency on chemicals for production
Loss of control over seeds

27. Commercial Agriculture
Term used to describe large scale farming and ranching operations that employ vast land bases, large mechanized equipment, factory-type labor forces, and the latest technology.
- roots are in colonial agriculture
- today, global production made
possible by advances in transportation and food storage

28. Advances in Transportation and Food Storage
- Containerization of seaborne freight traffic
- Refrigeration of containers, as they wait transport in Dunedin, New Zealand

29. Agriculture and Climate
Climate Regions (based on temperature and precipitation) help determine agriculture production.
Agriculture Regions – drier lands usually have livestock ranching and moister climates usually have grain production.

30. Loss of Productive Farmland
Farmland in danger of being suburbanized as cities expand into neighboring farmlands.

31. Agribusiness and the Changing Geography of Agriculture
Commercialization of crop production
new agricultural technologies: use of space, medicine, feeds
Poultry industry in the US: what was once concentrated production is now factory produced

32. Organic Agriculture Organic Agriculture –
The production of crops without the use of synthetic or industrially produced pesticides and fertilizers or the raising of livestock without hormones, antibiotics, and synthetic feeds.
- sales of organic foods on the rise
- grown everywhere
- demand in wealthier countries

33. Organic AgricultureMapping farms in the USA

34. Fair Trade Agriculture
Fair Trade Coffee –
shade grown coffee produced by certified fair trade farmers, who then sell the coffee directly to coffee importers.
- guarantees a “fair trade price”
- over 500,000 farmers
- produced in more than 20 countries
- often organically produced

35. Fair trade coffee farmer in El Salvador grows his beans organically and in the shade, allowing him to get a much better price for his coffee.
