1
Q
Boserup’s Thesis
A
Contradicts Malthusianism. As the population increases, so will technology and innovation ensuring the population will not die due to starvation. Population growth forces an increase in technology in the FARMING industry.
2
Q
Von Thunen’s Model
A
An economic model. It suggests a pattern for the types of products that farmers would produce at different positions which is relative to the distance from the market and commerce locations.
3

15
Q
What is a milkshed?
A
An area surrounding the milk source (dairy farm) where milk is supplied without spoiling.
16
Q
Bid-Rent Theory
A
A curve that indicates the starting position for each land use relative to the market, and where each land use will end up.
17
Q
How does the price increase in the Bid-Rent Theory?
A
Closer distance to the city/market, the higher the price
18
Q
How does the price decrease in the Bid-Rent Theory?
A
Farther the distance from the city/market, the cheaper the price
19
Q
Where does intensive agriculture go in the Bid-Rent theory?
A
Towards the center of the city
20
Q

48
What is Pastoral Nomadism?
Subsistence agriculture, practiced in the developing world, people travel from place to place with herds of their domesticated livestock
49
What is a result of Pastoral Nomadism?
People tend to leave the land once their livestock consume all the greens, resulting in exposure of the soil causing it to lose it's nutrients and fertility.
50
What is Transhumance?
The movement of people and livestock due to the changing of seasons and seasonal patterns, low land areas in the winter, highland areas in the summer

52
What is commercial agriculture?
Agriculture undertaken in order to generate products for sale off of the farm in order to make a profit
53
What is subsistence agriculture?
Involves food production mainly for the family. A farmer will grow most everything that the family would consume, and anything leftover will go to the local community rather than to a big market.

Terracing
Type of farming in which farmers build a series of steps into the side of hill to harvest crops
80
Irrigation
The process of diverting water from its natural course or location to aid in the production of crops
81
Overgrazing
The density of animals is greater than the grasslands; damage to the grasslands will not refresh itself even after animals leave
82
Deforestation
Removal of large tracts of forest that occurs mostly in Southeast Asia, parts of Africa, and rainforests in South America
