2Topic V Agriculture and Rural Land Use
3What is Agriculture?
- The modification of Earths surface through the
cultivation of plants and rearing of animals to
obtain subsistence or economic gain. - A crop is a plant cultivated by people.
4Agriculture
- 1/3 of all land area committed to agriculture use
- Developing countries 2/3 involved in
agriculture - Employment in agriculture is declining in
developing countries - lt 2 Million
5How does agriculture relate to geography?
- Geographers study where agriculture is
distributed. - LDCs agricultural products are consumed near
where they are produced - MDCs agricultural products are sold and consumed
away from where they are produced.
6How does agriculture relate to geography?
- Geographers study why farming practices vary
around the world. - Elements of physical environment that limit
agricultural production.
7How does agriculture relate to geography?
- Local diversity is shown in the environmental and
cultural mix influencing agricultural practices. - Globalization influences farmers to grow
profitable rather than practical crops.
8Classification of Economic Activities
- Primary
- Secondary
- Tertiary
- Quaternary
- Quinary
9Economic Geography
- Study of how people earn their living
- How livelihood systems vary by area
- And the spatial linkage between economic
activities
10Primary Activities
- Harvesting or extracting something directly from
the Earth - Humans in direct contract with the natural
environment - Hunting gathering, farming, livestock herding,
fishing, forestry
11Secondary Activities
- Add value to material by changing their form or
combining them into more useful/valuable
commodities - Intermediate products
- Manufacturing and processing industries
- Energy and construction industries
12Tertiary Activities
- Consists of those business and labor
specializations that provide services to the
primary and secondary sectors, general community,
and private individuals - service industries
- Linkage between producer and consumer
132 types of Tertiary Activites
- Quaternary services performed by white collar
professionals - Exchange of information, money, or capital
- Quinary high level decision making activities
- Spheres of research and higher education
14Primary Activities Agriculture
- Before farming hunting and gathering were the
universal forms of primary production - Use of tools and fire enabled sustainable
population growth in early communities - Cyclic Migration was the way of life
15The First Agricultural Revolution
- 12,000 years ago
- First conscious cultivation of plants
- Increased the carrying capacity of the Earth
- Caused changes in social organization and
technology
16The First Agricultural Revolution
- Living in permanent settlements
- Land ownerships
- Modification of the natural environment
- Trading economies
- Developed much later in the Americas than in
Southeast and Southwest Asia - Many agricultural hearths
17Diffusion of Agriculture
- Vegetative cultivation in S.E. Asia same time
(root removal) 14,000 years ago - Agriculture diffused from agriculture centers
through stimulus diffusion - Later through migration and colonialism
18Diffusion of Agriculture
- Seeds of agriculture began in the fertile
crescent (Iran and Iraq) 10,000 years ago - - because of seed selection,
- plants got bigger over time
- - generated a surplus of
- wheat and barley
- - first integration of plant
- growing and animal raising
- (used crops to feed livestock,
- used livestock to help grow crops)
19Diffusion of Agriculture
- Animal Domestication
- Fertile Crescent
- began about
- 8,000 years ago
20Animal Domestication
- Relatively few animals have been domesticated
- (all by 4500 years ago)
- Goats
- Sheep
- Pigs
- Cattle
- Horses
- Camels
- Yaks
- (Jared Diamond claims to be the five most
important animals) - Attempts at domestication continue, but most fail
-Llama -Alpaca -Turkey -Water Buffalo -Cats -Dogs
-Reindeer
21Carl Sauer
- Proposed that agriculture began in the Bay of
Bengal 14,000 years ago - The cultivation of roots and cuttings came first
(cassava, yams, and sweet potatoes) before seed
crops - Proposed other agricultural
- hearths
22World Areas of Agricultural Innovations
Carl Sauer identified 11 areas where agricultural
innovations occurred.
23Chief Source Regions of Important Crop Plant
Domestications
24Subsistence Agriculture
- Subsistence Agriculture
- Agriculture in which people grow only enough
food to survive. - - farmers often hold land in common
- - Total self-sufficiency
- - some are sedentary, and some practice
shifting cultivation
25World 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.
26Shifting Cultivation
- Clear land for planting by slash-and-burn,
cultivate crops for several years until it
becomes infertile - Leave land to lie fallow so soil can recover
- 5 of world pop. Still practice shifting
cultivation
27Slash and Burn
- Swidden agriculture areas of land cleared and
vegetation burned off, layer of ash increases
soils fertility - Very efficient with low pop/high land/ low tech

30Shifting Cultivation
- Crops rice in SE Asia, maize and cassava in S
America, millet and sorghum in Africa - Often the land is
- Used for multiple crops
- in subsistence
- Owned by village, and
- separated into family plots
31 32Shifting Cultivation
- Decreasing as a main type of subsistence
- Moving to more sophisticated types of agriculture
with help of state and global organizations - Deforestation of
- rainforests bringing
- global attention
- Brazil
33Boserup Thesis
- Population increases necessitates increased
inputs of labor and technology to compensate for
reduction in the natural yields of swidden
farming - Why?
34Intensive Subsistence Systems
- Work small parcels of land intensively
- Double cropping and crop rotation prevalent
- ½ of the worlds
- population
- Hundreds of millions
- of Chinese, Pakistanis,
- Bangladeshis, and
- Indonesians
35- Settling down in one place, a rising population,
and the switch to agriculture are interrelated
occurrences in human history. - Hypothesize which of these three happened
first, second, and third, and explain why.
36Second Agriculture Revolution
- 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
37Second Agricultural Revolution
- Began slowly during the middle ages
- Modification of tools and equipment of
agriculture - Increased efficiency of food storage and
distribution - Increased productivity
- Aided in the growth of large urban areas
38Industrial Revolution
- Aided the Second Agricultural Revolution
- Tractors and Machines
- Changed the cultural landscape of
agriculture.how?
39Von Thunens Model of Farming
- The modification of farming culture created a
desire for a spatial understanding of
agricultural layout - Created in the 1800s
- Based on cities in Germany near Von Thunens farm

41Reasons
- Profitable options decrease with distance from
the market - Rent differences reflects different values of
distance - Production Costs Transportation Costs
economic margin for a crop - Greater the transport cost the less rent a farmer
can afford
42Contemporary Variables
- More efficient transportation
- Transportation cost no longer proportional to
costs - Firewood not a factor
- Technology has reduced perishability
43The Third Agricultural Revolution
- Creation of the New World
- Late 19th Century and gained momentum through
the 20th Century - Big differences between the 2nd and the 3rd is
degree
44The Third Agricultural Revolution 3 Phases
- Mechanization, chemical farming with synthetic
fertilizers, and globally widespread food
manufacturing
45Mechanization
- Replacement of human labor with machines
- Tractors, combines, reapers, pickers, since late
1800s
46Chemical Farming
- Application of synthetic fertilizers to the soil
- Also herbicides, fungicides, and pesticides
- Important environmental impact
47Food Manufacturing
- Adding economic value to agricultural products
through a range of treatments - Processing, canning, refining, packing, packaging
48The Third Agricultural Revolution
- The Green Revolution
- Began in the 1960s
- Scientists created IR36an artificial rice
plant - By 1992 IR36 was the
- most widely grown
- crop on Earth
49The Green Revolution
- New high-yield hybrid varieties of wheat and corn
were developed and diffused - Disastrous famines of the past have been avoided
- Asia saw a two-thirds increase in rice production
50(No Transcript)
51Negatives of the Green Revolution
- New hybrids required use of chemical fertilizers
and pesticides - Can lead to reduction of organic matter in the
soil - Many small-scale
- farmers lack resources
- to acquire these
- chemicals and the seed

53Agricultural Landscape
- The agricultural imprint of cultivation on the
land - The patterns of fields and properties created as
people occupy land for the purpose of farming
54Cadastral System
- A system the delineates property lines
- Adopted in places where settlement could be
regulated by law - Main Type Township-and-range system
55Township-and-range system
- Designed to facilitate the dispersal of settlers
evenly across farmlands of the interior - Basic unit section (1sq. Mi of land)
- Land frequently bought in half or quarter
sections - Townships (36 sq. mi) serve as political
administrative subdistricts
56Township and Range The cultural landscape of
Garden City, Iowa reflects the Township and Range
system. Townships are 6x6 miles and section lines
are every 1 mile.
57Metes and Bounds Survey
- Natural features used to demarcate irregular
parcels of land - Used commonly along the eastern seaboard
- Rivers, lakes, streams, mountains
58- Tennessees 3rd Surveyors District using Metes
and Bounds to describe the plot
59Long-Lot Survey System
- Long, narrow unit block stretching back from a
road, river, or canal - Central and Western Europe, Brazil, Argentina,
Southern Louisiana, Texas
60Longlot Survey System The cultural landscape of
Burgandy, France reflects the Longlot Survey
system, as land is divided into long, narrow
parcels.
French Long Lot agricultural fields in Louisiana
61Dominant Land Survey Patterns in the US
62Agricultural Villages
- Linear Village
- Cluster Village (nucleated)
- Round Village (rundling)
-
- Walled Village
- Grid Village
63Village Forms
64Functional Differentiation within Villages
- Cultural landscape of a village reflects
- Social stratification
- Differentiation of buildings
- Cultural norms
- Economic way of life
- Levels of Interdependence
65Stilt village in Cambodia Buildings look alike,
but serve different purposes.
66Farm in Minnesota each building serves a
different purpose
67Commercial Agriculture
- Production primarily for sale to processing
companies, not for individual consumption - MDCs, semi-peripheral, core
- Machinery and biotechnology
- Dairying, grain farming, Livestock higher costs
68Commercial Agriculture
- Roots Plantation Farming
- Latin America, Africa, and Asia
- Specialization in one or two crops
- ex cotton, sugarcane, coffee, rubber, tea
- Large labor force needed, often live on the
plantation - Today global production made possible by
advances in transportation and food storage
69Commercial Agriculture
- More land needed why has the amount of farm
land increased, while farms have decreased in the
US? - Closely tied to other food processing business
chain called agribusiness employs 20 of US labor
70AgribusinessThe industrialization of
Agriculture
- Created by advances in science and technology
- Process of the farm moving from the centerpiece
of agriculture production to being on part of an
integrated (vertical) industrial process - eg. Poultry industry in
- the US

75Organic 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

77Organic Agriculture
78Fair 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
79 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.
80Tragedy of the Commons
- "Therein is the tragedy. Each man is locked into
a system that compels him to increase his herd
without limitin a world that is limited. Ruin is
the destination toward which all men rush, each
pursuing his own best interest in a society that
believes in the freedom of the commons. Freedom
in a commons brings ruin to all.
