began in W. Europe during 1600s, promoted higher yields per acre per farmer; made it possible to feed rapidly growing cities; increase use of fertilizer, improved collars
fencing or hedging large blocks of land for experiments with new techniques of farming; early 1700s
crop rotation
controll nutrients in the soil by changing new vegetation annually
seed drill
made planting seeds more effecient
how the second agricultural revolution lead to the industrial revolution
better nutrition boosted population which created labor (necessary component)

replace work done with hand tools and animal power; tractor, planters, farm machines
scientific advances
herbicides, ferilizers; boost crop yields and health of animals
farm size (LDC v MDC)
commercial farmers have a larger amount of land than subsistence
intensive subsistence
large amount of output per acre through concentrated farming; most work done by hand; requires great deal of time and attention but under ideal conditions can provide large amounts of food per unit of land
ex. wet rice in east and south asia
wet or lowland rice
dominant in east and south asia; wet rice planted on dry land in a nursery, moved as seedlings to a flooded field to promote growth

crop rotation
each field planted on a planned cycle
cereal grains
oats, wheat, rye, barley
dairy farming
farms close to market bc the product will spoil easily; disadvantages: expense of feeding cows in the winter; farmers must purchas all feed; labor intensive
a ring of milk production around a major city
grain farming
Canada, Australia, Argentina, France, UK; lots of mechanism, labor concentrated in planting and harvesting seasons; world's leading export crop

practiced in arid or semi-arid regions, commercial grazing of livestock; most land is leased from the government, not much anymore
prairies of argentina, southern brazil and uruguay
mediterranean agriculture
exists only in the lands that border mediterranean sea, california, chile, southwest South Africa and southwest Australia - border seas and west coasts of continents; crop production for human consumption; horticulture is the base; major crops: olives, grapes, fruits, vegetables, olive oil, wine
growing of fruits, vegetables, and flowers
commercial gardening and fruit farming
predominates southeast US; truck farming; apples, asparagus, cherries, lettuce, mushrooms, tomatoes mainly sold processed to consumers; rely on machinery and fertilizers, labor only when they hire migrant farm workers
truck farming
same as commercial gardening and fruit farming
plantation farming
a farm that specializes in one or two crops, raised for export to high-consumption developed countries, persist in poorer countries, owners import workers and provide shelter for them; found in latin america, africa and asia
cash crops
crops raised to make money for their owners; plantation farming
factors determining what to grow?
subsistence- land and climate
commercial- access to markets, competition from other farmers and government regulations and subsidies
Von Thunen's Model
close to far from market- market gardening and dairy, forest, field crops, animal grazing;
model for land use in early 18 century; spatial layout of Rostock
marketing gardening and dairy
closest to market because products are perishable; and expensive to deliver
towns surrounded by belts of forests > wood and fuel for construction; trees are bulky and hard to transport
field crops
less perishable items; wheat and other grains; rotated from one year to another
animal grazing
outermost ring; required lots of space; beyond this was unprofitable bc transportation costs too high
assumptions by Von Thunen
a flat terrain with uniform soils and no significant barriers to transportation to market.
location theory
a general but logical attempt to explain how an economic activity is related to the land space where goods are produced
dispersed settlement pattern
areas of extensive agriculture practices and when machinery makes large intensive cultivaion areas possible; individual farmhouses lying quite far apart
nucleated settlement pattern
villages located quite close together with relatively small surrounding fields; land use intense
villages or small clusters of buildings
factors determining housing
geography; lifestyles; until recently, physical environment for materials; rural vs. urban
originated in northern Europe, spread to north America (when europeans settled there); not usually used for primary building, used for framing and trimming instead; made primarily of wood = scandinavia through russia

growing of specialized crops because they seem to be most profitable
spreading to developing countries where small-size farmers are linking with foreign sources
third agricultural revolution
began in mid-20th century; still going on today in the form of industrial revolution;
industrail agriculture
modern farming that refers to the industrialized production of livestock, poultry, fish adn crops; innovation in agricultural machinery and methods, genetic technology, techniques for achieving economies of scale production; methods widespread in developed nations
the use of genetically altered crops in agriculture and DNA manipulation in lviestock in order to increase production

collection of new agricultural techniques; use of new higher-yield seeds and expanded use of fertilizers;
impact of green revolution
famine for ppl in sub-saharan africa = lack of resources to buy seed, fertilizer and machinery + population growth; land overgrazed by animals; soils exhausted from overplanting; desertificiation;
land becoming desert; because of overgrazing and over planting; and trees being cut
environmental impacts of modern agriculture
erosioin; changes in the organic content of soil, depletion of natural vegetation; presense of chemical in soils and groundwater
green revolution good/bad?
good: oupaces population growth; nitrogen based fertilizers; new food sources; reducing dependency on imports; increased crop yields; increased productivity of cash crops
bad: poor countries cannot afford; over fishing; irrigation led to groundwater depletion; raising one type of crop means no variety for balanced diet
