Unit 5 - Agriculture Test Review Flashcards
The deliberate modification of
Earth’s surface through
cultivation of plants and the
rearing of animals to obtain
sustenance or economic gain.
Agriculture
Before agriculture
hunting and gathering, small groups of people
1st Ag Revolution (Neolithic Revolution)
humans first domesticated plants + animals and no longer relied entirely on hunting & gathering
Ag hearths
Ag developed independently of each other (independent hearths)
taboos in ag
Some regions can produce things but may not necessarily eat them
how industrial rev affects the 2nd ag rev
with industrial we get more tools which we can use to get higher yields
Farm size
in MDC’s farm size is relatively large, Large size is due to
mechanization
Southwest Asia (Fertile
Crescent) crops
Barley, wheat,
lentil, olive
East Asia crops
Rice, millet, soybean
Sub-Saharan Africa crops
Sorghum, yams, millet, rice, coffee
Latin America cops
Beans, cotton, potato, corn
Southwest asia animals
Cattle, goats, pigs, sheep, dogs
Central asia animals
horses
what are agricultural regions influenced by
climate, soil, landforms
two things that normally determine ag regions
climate, cultural preferences
cultural preferences
in regions where something is taboo you will not see those type of farms.
1st ag rev effects
Urbanization, Social Stratification, Occupational Specialization, Increased population densities
second ag rev
goes with industrial rev
SET
Science, Entrepreneurship, Technology
2nd ag rev - science
3 Field System, 4 Field System, selective breeding of animals
2nd ag rev - Entrepreneurship (business)
bigger farms = more food
2nd ag rev - Technology
Better tools = More Food
Technology
allows much greater production
(surplus) with less human labor, but has high social and environmental costs.
increased food production
leads to Better diet, Longer life, More people available to work in
factories.
Subsistence Agriculture
the production of food primarily for consumption by the farmer’s family
Commercial Agriculture
The production of food primarily for sale off the farm
LDC purpose of farming
Food to eat -Subsistence
MDC purpose of farming
Food to make money - commercial
percentage of farmers in LDC
high %
percentage of farmers in MDC
low %
machinery in LDC
basic animal, wood, & iron tools
machinery in MDC
highly advanced, electronic
machines
why is commercial agriculture expensive
cost of new machines
Agribusiness
incorporation of farms into major food production industry
what is involved in agribusiness
processing, packaging, storing, distributing, and retailing
LDC agriculture
Pastoral Nomadism, Shifting Cultivation, Plantation Farming, Intensive Subsistent Agriculture
Wet rice dominate, Intensive Subsistent Agriculture Wet rice not dominate
Pastoral Nomadism
Subsistence agriculture
based on herding animals, dry areas, Animals provide milk and their skin clothing and tents
what do Nomads practice
transhumance
seasonal migration of livestock between mountains and pasture areas
transhumance
what animals dominate the Middle East and North Africa
Camels, followed by sheep & goats
A form of subsistence
agriculture in which people shift
activity from one field to
another; each field is used for
crops for a relatively few years
and left fallow for a relatively
long period.
Shifting Cultivation
Shifting Cultivation method
slash-and-burn, or swidden agriculture
how slash and burn works
Farmers clear land
by slashing , then
burning it, then food is grown for a few years until the soil is depleted of resources, then left to fallow.
where is shifting cultivation practiced
humid low- latitudes (high temperature, high rainfall)
shifting cultivation crops
Maize, Cassava, yams are most dominant crops
shifting cultivation pros and cons
No fertilizers, or pesticides, Inefficient way to feed people, fields are not permanently cleared
Plantation farming
Tropics, subtropics, In LDC, but owned by MDC, Commercial agriculture, One or two crops
Plantation farming crops
cotton, sugarcane, coffee, rubber, cocoa, bananas
Intensive
Small amount of land, Feed a lot of people
Extensive
Lots of land, Not as
much output of food
Intensive Subsistent Ag
Cultivation at a high density or
high production out of small
parcel of land
where does Intensive Subsistent Ag dominate
Southeast Asia
Intensive Subsistent Agriculture
Wet rice dominate
Flat land prepared with
animal, field flooded, Rice seedlings transplanted, harvested by knives
what is a field flooded known as
sawah
