Title: Agriculture and Rural Land Use
1Agriculture and Rural Land Use
2Introduction
- Nomads
- HUNTERS AND GATHERERS
- AGRICULTURE
- The process of growing plants or raising of
animals to produce food for sustenance or sale at
the marketplace - Farming practices differ in MDCs vs. LDCs
- In Asia, most people are SUBSISTANCE FARMERS
- Growing only enough food to feed their family
- In MDCs, COMMERCIAL FARMING dominates
- Farms produce food to be sold in groceries and
markets, not just for the farmers themselves
3Classifying Agricultural Regions
- LDCs subsistence agriculture
- MDCs commercial agriculture
- Subsistence vs. commercial agriculture
- Subsistence agriculture is the production of food
primarily for consumption by the farmers family - Commercial agriculture is the production of food
primarily for sale off the farm
4Key Questions
- Where did agriculture originate? How and where
did it spread? - What are the characteristics of the worlds
agriculture regions? How do these regions
function? - How has agricultural change affected the
environment and peoples quality of life? - How does diet, energy use, and varying agrarian
technology relate to agricultures origination? - What are different types of extensive and
intensive agricultural practices? What are
settlement patterns and landscapes related to
each agriculture type?
5Cont
- What are land survey systems, environmental
conditions, and cultural values linked to each
agriculture type? - Why do different agricultural practices exist
where they do? - What is the von Thunen model?
- What is the status of food supplies throughout
the world? Can humans increase the food supply
and reduce starvation and malnourishment?
6Origin of Agriculture
- An evolution of knowledge over thousands of years
- As humans constantly touched and handled plants
while gathering food, innovations occurred and
diffused from multiple hearths (places of origin) - According to CARL SAUER humans first learned how
to grow plants through VEGETATIVE PLANTING - Cutting off a stem of another plant or by
dividing up roots of a plant
7Cont
- It is believed women were responsible for
discovering vegetative planting because of their
sociological position as gatherers and medicinal
healers - Later humans make the leap to
- SEED AGRICULTURE
- Farming is through planting seeds rather than
simply planting part of the parent plant - Leads to higher crop YIELDS because there are so
many seeds
8Agricultural Hearths
- Carl Sauers theory of a vegetative hearth argues
that vegetative farming knowledge first
originated in SE ASIA - Climate and terrain there would have supported
the growth of root plant that are easily divided,
such as taro, yam, banana, and palm - From the hearth, it diffused north and east to
China and to Japan, and then west toward SW Asia,
Africa, and the Mediterranean
9Other vegetative hearths
- Others emerged through INDEPENDENT INNOVATION
- NW South America
- West Africa
10First Agricultural Revolution
- Sometimes called the NEOLITHIC REVOLUTION
- Brings SEED AGRICULTURE and the use of
animals/DOMESTICATION in the farming process - About 12000 years ago
- Replaced nomadic hunting
- Human groups able to stay in one place
- Leads to
- population growth
- Build communities
- Produce more food
- Increased CARRYING CAPACITY
- Development of civilization/culture
11SEED AGRICULTURAL HEARTHS
- Western India
- Diffusion to SW Asia
- Crop innovation Wheat and Barley
- SW Asia (Tigris/Euphrates rivers)
- Diffusion to Europe N. Africa NW India/Indus
river area - Crop innovation Integrated seed agriculture with
domestication of herd animals such as sheep,
cattle, and goats
12Cont
- N. China
- Diffusion to S. Asia and SE Asia
- Crop innovation Millet
- Ethiopia
- Diffusion to NONE
- Crop innovation Millet
- S. Mexico
- Diffusion to Western Hemisphere
- Crop innovation Squash and Corn
- N. Peru
- Diffusion to Western Hemisphere
- Crop innovation Squash, cotton, beans
13Second Agricultural Revolution
- After fall of Rome around 500 CE, farming grew
into a feudal village structure - During Middle ages most farmers use SUSTENANCE
FARMING in an - OPEN LOT SYSTEM
- One in which there was one large plot of
community farmland that all villagers worked to
produce a crop to eat - As capitalism grew, feudalism diminished and
villages enclosed their farmland
14Enclosure Movement
- Gave individual farmers their own land marks a
shift in agriculture from CLUSTERED RURAL
SETTLEMENTS to DISPERSED RURAL SETTLEMENTS - Most influential during the 17th and 18th
centuries during Englands Industrial Revolution - Growing industry and decline of Feudalism leads
to URBAN MIGRATION - Former farmers moving to the cities for work
- Caused a jump in food demand from farms into
cities - With demand comes innovation
152nd agricultural revolution innovation
- Better collar for oxen
- Use of horses instead of oxen
- New fertilizers
- Field drainage
- Irrigation systems
- Storage systems
- ALL INCREASED YIELD and ENCOURAGE POPULATION BOOM
16Major Agricultural Production Regions
17Subsistence Agriculture
- Practiced in LDCs
- 3 Types
- Shifting cultivation
- Intensive subsistence
- Pastoralism
181. Shifting Cultivation
- EXTENSIVE AGRICULTURE
- Large amts. Of land not as much food
- Farmers rotate the fields they cultivate to allow
the soil to replenish - Different than CROP ROTATION
- Found often in the TROPICAL ZONES (rain forest
regions in Africa, Amazon river basin in S.
America, and SE Asia) - Topsoil is thin in these areas means less
nutrients - Mainly due to heavy rains that wash it away
19Cont
- SLASH AND BURN
- SWIDDEN
- Cleared land
- Not dependent on technology
- May utilize INTERTILLAGE
- Mixing various seeds on one plot of land
- Each plot will last 2-3 years then they move on
- FALLOW
- The land not being used
20Cont
- Use A LOT of land
- 25 of earths land
- Cannot produce large amounts of food
- Because of this many have tried to switch to
commercial forms of farming instead - May have criticisms from local culture
212. Intensive Subsistence Agriculture
- INTENSIVE AGRICULTURE
- Small amts. Of land large amount of food
- Make the most use of land
- But still SUBSISTENCE AGRICULTURE
- Usually found in highly populated areas
- China, India, SE Asia
22Cont
- Rice is the dominant intensive susbsistence
agriculture crop in S. China, India, SE Asia, and
Bangladesh - Summer rainfall is abundant
- Where winters are too cold for rice grains are
grown - Some places may engage in DOUBLE CROPPING
23Pastoralism
- The breeding and herding of animals to produce
food, shelter, and clothing for survival - Usually practiced in places with little arable
land - Can be sedentary or nomadic
- N. Africa, Central and Southern Africa, Middle
East, Central Asia
24Cont
- Transhumanence
- The movement of animal herds to cooler highland
areas in the summer to warmer, lowland areas in
the winter - Pastoral farmers usually trade with local farmers
for food/supplies - Depend on Trade for survival
- Overall it is declining since the land they use
is being used for other things
25Mediterranean Agriculture
- Primarily associated with the mediterranean sea
area and places with hot, dry summers and mild,
wet winters. - California, Chile, S. South Africa, South
Australia - Wheat, barley, vine and tree crops, grazing
- Olives, grapes, and figs are staple crops
- Can be Intensive or Extensive depending on crop
- Can be Subsistence or Commercial
26COMMERCIAL FARMING
- Mixed crop and Livestock farming
- Ranching
- Dairy
- Large scale grain
- Plantation (mainly practiced in LDCs)
27Mixed Crop and Livestock Farming
- Involves growing crops AND raising animals
- Most crops used to feed the animals
- This produces manure fertilizer for sale and
goods such as eggs - Most income comes from animal products
- Reduce dependence on seasonal harvests
- Europe and E. North America
- Near Urban areas mainly
- May engage in crop rotation
28Ranching
- Commercial grazing, or the raising of animals on
a plot of land on which they graze - Usually extensive
- Cattle and Sheep in demand for wool and meat
- Usually practiced in areas too dry to support
crops - USA, Argentina, S. Brazil, Uruguay
- Declining in practiced
29Cont
- Many US ranches are being converted to
fattening ranches on which fixed lot cattle are
fattened then slaughtered - Also found in Tropical areas of Latin America and
N. Mexico - Too wet to grow crops there
- Decline in ranching due to cost vs. crops
30Dairying
- Growth of milk based products for the marketplace
- Usually close to the marketplace
- Usually small and labor intensive
- CAPITAL INTENSIVE FARMS vs. LABOR INTENSIVE FARMS
- MILKSHED
- Has expanded with technology along with the
amount a cow can produce
31Large Scale grain farms
- Grains most often grown to be exported to other
places for consumption - Canada, US, Argentina, Australia, France,
England, and Ukraine - Ukraine once considered Russias breadbasket
- US worlds largest producer
- Wheat is leading export crop
- US and Canada produce ½ of the worlds grain
- Most grain worldwide is grown to feed animals
- Saw expansion during the industrial revolution
- Usually highly mechanized and thus Capital
Intensive - McCormick Reaper
- The Combine
32Plantation Farming
- Large farms specializing in one or two crops
- Tropical and subtropical zones in colonized areas
- Coffee, tea, pineapples, palms, coconuts, rubber,
tobacco, sugarcane, and cotton - Usually in LDCs but owned by companies in MDCs
- Usually in coastal areas with easy access to
exports - Still Labor intensive
33Rural Land Decisions on Farm Locations
34Physical Factors
- Appropriate environment for cultivating varies
depending on the type of crop - Farmers can mold the environment
- Environmental determinism vs. possibilism vs.
cultural determinism - Farmers evaluate
- SOIL
- Depth, texture, nutrient composition, acidity
- RELIEF
- shape of the field includes slope and altitude
- Might look at sun exposure time
- Flat lands are best sloped are difficult to
irrigate - Altitude can affect temperature
- CLIMATE
- TEMP and RAINFALL are most influential factors
- Different crops require different water and temp
35Political-Cultural Factors
- Political and cultural factors also influence
agricultural decisions - Ex. Hinduism holds cattle sacred It is taboo in
Islamic religions to eat pigs - Ex. Immigrants often carry with them their
homelands farming practices and food preferences - Food taboos not always religious although
nutritious the US does not eat horse
36Cont
- Political decisions also make an impact
- In LDCs governments encourage use of tech
- During Green Revolution (3rd agricultural
revolution 1960s-1990s) many LDCs tried to
subsidize the use of efficient seed types that
were more expensive - European Union pays farmers to NOT grow crops in
an attempt to eliminate massive surpluses that
drive prices down to nothing - National treasure crops France (grapes)
- France also turns its lower quality grapes into
biofuel
37Economic Factors
- Land rent
- The price a farmer must pay for each acre of land
- A farms location is related to how much money
the farmer can make from a crop to pay the rent - Rent is cheaper farther away from a city
- Therefore extensive farming takes place farther
away from the city

39Agricultural Location Theory
- Von Thunen 19th century German economist
- Model attempts to explain and predict where and
why various agricultural activities take place
around a citys marketplace - EXPLAINS and PREDICTS
- Agricultural land use patterns
40Von Thunen model
- Contains a Central Marketplace
- Farmland is equally farmable and productive
- Only one form of transportation
- Only variable that could change (according to Von
Thunen) was distance - Results in concentric rings of Agricultural
activities - Moving outwards from a marketplace results in
more extensive farming Intensive agriculture
took place more towards the center

43Explanation
- Land rent and Transportation costs explain
pattern - Closer to city more expensive
- More perishable crops are closer
44Usefulness of Model
- If you only have one variable Transportation
costs then it is useful - Unfortunately we have more variables
- He tried to remodel the model later with the
introduction of a river - Tried to introduce differing soil qualities later
- Overall it shows the INFLUENCE OF DISTANCE in
human decision making - Like all models, researchers try to use his model
to predict future land use
45Settlement Patterns in Villages
- Village
- May vary by culture
- Usually related to function and environment
- In Europe, villages were often clustered on a
hillside to leave the flatlands for farming and
village protection - In lowland areas a linear pattern emerges
following the river (long lot system in France) - Many places built with a grid pattern with
geometric boundaries (USA) - Throughout Europe, Asia, Africa a round pattern
space in middle for cattle
46Housing Materials
- WOOD
- Eurasia, US Pacific Coast, N. America, Australia,
Brazil, Chile - STONE
- Europe, Egypt, India, W. China, Yucatan, Mexico,
S/Central Africa, Middle East - GRASS AND BRUSH
- Low latitude regions African Savanna, E. African
Highlands, S. Africa, S. American highlands, N.
Australia - POLES AND STICKS
- Africa, SE Asia, W. Africa, Amazon Basin
- SUN DRIED BRICKS
- Middle East, Middle and S. America, N. China,
African Savanna, N. Africa - OVEN BAKED BRICKS
- Modern, contemporary areas in MDCs
47Modern Commercial Agriculture
48Third Agricultural Revolution
- Green Revolution evolves from the 3rd
agricultural revolution - Distributed mechanized farming, chemical
fertilizers on a global level - Farming and food processing were at different
sites
49Industrializing the farm process
- Harvest and ship off for marketing and
distribution - Factory system
- AGRIBUSINESS
- The system of food production involving seed
development to marketing and sale of the food
products - Integral to US and Global Economy
- Think about milk before and after the 3rd
agricultural revolution
50Globalization of the farming process
- Colonialization/ Imperialism led to
core/periphery regions - Colonies used to supply
- Neocolonialism/Post colonialism
- Many foods in grocery stores grown in LDCs and
shipped to MDCs - TRUCK FARMS- growing a crop to supply a distant
market
51Human Impact of the Industrialization of
Agriculture
- Local farmers forced to integrate into the larger
AGRIBUSINESS - Agriculture companies subcontract with the locals
- Local flower farms forced to close since they
cannot compete with TRUCK FARMS - In 1920 in US 1 in 3 lived on a farm
- In 1978 only 1 in 28
52Cont
- In LDCs farmers are forced to sell their land
- LDCs rely on exports too much and dont supply
their own people - Profits in LDC farms not reinvested
53Green Revolution
- 1940s-1990
- Developed hybrid high yield seeds
- Dramatically improves output
- Started out with US research into improving
Mexicos wheat grain production - Also developed new fertilizers and pesticides to
protect and nourish new crops - The miracle of the revolution was diffusion of
higher yield grains - Nobel Prize given to Norman Borlaug for work to
reduce world hunger
54Downside
- Less labor needed
- Higher yield seeds more prone to viruses and pest
infestation - Some seeds not farmable in certain areas
- Some argue it has increased economic inequality
in the periphery - May cause pollution and soil contamination
55Biotechnology
- Using living organism to produce or change plant
or animal products - GENETIC MODIFICATION
- Uses scientific manipulation of crop and animal
products to improve agricultural products and
activity - BIOREVOLUTION
- The extension of scientific innovation to all
crops and animal products
56FAST FACT
- The US produces nearly 63 percent of the worlds
genetically modified crops - 33 of US corn and 55 of US cotton is
genetically modified - Biotech research is designing bananas containing
vaccines against hepatitis
57Controversies/Benefits of Genetically Modified
foods
- Benefits
- Taste
- Reduce malnutrition
- Increase yields
- Improved resistance to disease, pests, and
herbicides - New products and growing techniques
