Let’s talk about farming!!

• What are the components…when you think of farming, what do you think of?

Where Did Agriculture Originate?

• Origins of agriculture– Agriculture = deliberate modification of

Earth’s surface through the cultivation of plants and/or rearing of animals• About 10,000 years ago

– Cultivate = “to care for”– Crop = any plant cultivated by people

Where Did Agriculture Originate?

• Origins of agriculture– Hunter-gatherers

• Perhaps 250,000 remaining today

– Invention of agriculture• When it began = unclear• Diffused from many hearths

Where Did Agriculture Originate?

• Commercial and subsistence agriculture– Subsistence = produced mainly for the

farm family’s survival• Most common in LDCs

– Commercial = produced mainly for sale off the farm• Most common in MDCs

Where Did Agriculture Originate?

• Commercial and subsistence agriculture– Five characteristics distinguish commercial

from subsistence agriculture• Purpose of farming• Percentage of farmers in the labor force• Use of machinery • Farm size• Relationship of farming to other businesses

Where are Agricultural Regions in LDCs?

• Shifting cultivation– Most prevalent in low-latitude, A-type

climates (south America, central west Africa, southeast Asia)

– Two features:• Land is cleared by slashing and burning debris

– Slash-and-burn agriculture

• Land is tended for only a few years at a time

– Types of crops grown vary regionally– Traditionally, land is not owned individually

Page 15: © 2011 Pearson Education, Inc. As I Enter 4.8.2013 Farming…What do we know, what are we going to study, why should we care. Agenda –Weekend Recap –This.

Where are Agricultural Regions in LDCs?• Pastoral nomadism (herding domesticated

animals)

– Found primarily in arid and semiarid B-type climates (central Southwest Asia, North Africa)

– Animals are seldom eaten• The size of the herd indicates power and prestige

– Type of animal depends on the region• For example, camels are favored in North Africa

and Southwest Asia

– Transhumance practiced by some pastoral nomads

Where are Agricultural Regions in LDCs?

• Intensive subsistence– Found in areas with high population and

agricultural densities• Especially in East, South, and Southeast Asia • To maximize production, little to no land is

wasted

– Intensive with wet rice dominant– Intensive with wet rice not dominant

Where are Agricultural Regions in LDCs?

• Plantation farming– Found in Latin America, Africa, and Asia– Products are grown in LDCs but typically

are sold to MDCs– Plantations specialize in one or two cash

crops• Important crops = coffee, sugarcane, cotton,

rubber, and tobacco

– A large labor force is usually needed in sparsely settled regions

Where are Agricultural Regions in MDCs?• Mixed crop and livestock farming

– Most land = devoted to crops to feed animals…

– Most profits = derive from the livestock• Advantages – livestock supply manure,

workload more evenly distributed.

• Dairy farming– Regional distribution: the Milkshed (near markets.)

– Two primary challenges• Labor-intensive• Expense of winter feed

Where are Agricultural Regions in MDCs?

• Grain farming (wheat, corn, oats, barley, rice)– The largest commercial producer of grain = the

United States

• Livestock ranching– Practiced in marginal environments – too dry for

other forms of agriculture. – If irrigation is possible ranching ends.– Many cattle shipped to feed lots for fattening.

Where are Agricultural Regions in MDC’s?

• Mediterranean agriculture– Based on horticulture– Crops grown for human consumption – Animals/animal products less important traditionally.

• Commercial gardening and fruit farming– Truck farming (NOTHING TO DO WITH TRUCKS!)

– Perishable produce– Grown near markets

Agriculture and the Environment• Agriculture is severely constrained by

– Climate– Terrain– Soil

• Can have strong devastating impact on environment.– Slash and Burn– Overgrazing– Desertification– Irrigation

Agriculture and Economics: Subsistence Agriculture

• Population growth– Must produce more food

• International Trade– Many subsistence farmers do produce

cash crops• Most profitable = Drugs

Why Do Farmers Face Economic Difficulties?

• Challenges for commercial farmers– Access to markets is important

• The von Thünen model (1826)– The choice of crop to grow is related to the proximity to

the market

Why Do Farmers Face Economic Difficulties?

• Challenges for commercial farmers– Overproduction

• Agricultural efficiencies have resulted in overproduction

• Demand has remained relatively constant– As a consequence, incomes for farmers are low

– Sustainable agriculture• Sensitive land management• Integrated crop and livestock

Why Do Farmers Face Economic Difficulties?

• Strategies to increase food supply– Expanding agricultural land

• Desertification

– Increasing productivity • The green revolution

– Identifying new food sources• Cultivating oceans, developing higher-protein

cereals, and improving palatability of foods

– Increasing trade
