1
New cards

agriculture

the process by which humans alter the landscape in order to grow crops and raise animals for consumption and trade

2
New cards

access to water, nutrients, layout of land

what physical factors affect agriculture? (3)

3
New cards

high latitudes, high elevations, high or low precipitation

what are rare exceptions for agriculture? (3)

4
New cards

development, access to technology

what depends on the ability to overcome agricultural challenges?

5
New cards

substinence agriculture

goals are to grow enough food and raise enough livestock to meet needs of family, sell or trade any surplus crops and animals, more common in less developed, typically small farms around 2 acres

6
New cards

commercial agriculture

goal is to grow and raise enough food to sell for a profit, common in developed countries but has become more common in semi periphery countries, uses more advanced technology and equipment

7
New cards

intensive agricultural practices

farmers and ranchers focus on maximizing fields from smaller areas by using inputs like fertilizer and pesticides, machinery, and labor

8
New cards

extensive agricultural practices

farmers and ranchers use fewer amounts of inputs and machinery and less intensive labor, typically on larger areas of land

9
New cards

pastoral nomadism

substinence extensive agriculture that is practiced in arid and semi-arid climates, move their herds to different pastures within their territory to trade meat for crops, rely on animals for food, clothing, and shelter

10
New cards

shifting cultivation

a type of substinence extensive farming, where farmer grows one crop and moves it to a new field when the soil of the existing field loses fertility, land is usually owned

11
New cards

crop rotation

farmers grow multiple crops in a set number of fields, every year the farmer rotates the crops so that the same crop is not being grown in the same field in successive years, allows for replenishment of nutrients resulting in more productive fields

12
New cards

slash and burn agriculture

shifting cultivation in tropical areas, farmers clear the land by burning vegetation, enriches poor soil by adding nitrogen to it, once soil becomes infertile they will move and repeat this process, unsustainable as it wastes land

13
New cards

plantation

intensive commercial agricultural practice consisting of large commercial farm that specializes in one crop. found in hot, humid climates, with substantial rainfall, labor intensive and exploit low wage workers

14
New cards

mixed crop and livestock farming

intensive commercial integrated system that demonstrates interdependence between crops and animals, common in developed regions

15
New cards

grain farming

grown in dry regions where it is hard to grow other crops, used to feed livestock and people, the type that is grown depends on climate

16
New cards

spring wheat

planted early spring and grown in colder regions

17
New cards

winter wheat

planted in the fall and is grown in warmer regions

18
New cards

truck farming

intensive farming where products are driven from farms to local urban markets where the items are sold

19
New cards

market gardening

when fruits and vegetables are grown near an urban market and are sold to local suppliers, stores, restaurants, etc., has become popular because of “buy local” movements

20
New cards

dairy farming

used to be local, family owned farms that supplied products to a small geographical area, is now replaced by large corporate operations that resulted in fewer farms, but more production, are located in urban centers and transportation corridors in developed countries

21
New cards

milk shed

the geographic distance that milk is delivered

22
New cards

mediteranean agriculture

practiced in regions with hot, dry summers, mild winters, narrow valeted, and often some irrigation, herds have often practiced transhumance

23
New cards

transhumance

the seasonal herding of animals from higher elevations in summer to lower elevation and valleys in winter

24
New cards

livestock ranching

extensive commercial practice of the grazing of animals confined to a specific area, typically found in areas that are to grow crops in large quantities

25
New cards

first/neolithic agricultural revolution

the change from primarily nomadic hunter-gatherer societies to settled subsistence-based agricultural communities, began in agricultural hearths

26
New cards

agricultural hearths

areas that are believed to develop independently of one another (carl sauer)

27
New cards

independent innovation

animals and plants that are domesticated in multiple regions with seemingly no interaction among people

28
New cards

permanent settlements, communities along water, freedom for hunting gathering, development of buildings and new jobs

the development of agriculture led to…(5)

29
New cards

clustured settlements

rural residents, groups of homes, has a strong sense of place and shares services and schools, villagers raise crops and animals in the fields around their settlements

30
New cards

dispersed settlements

common for North American farmers, lived in homes spread throughout the countryside, occur in areas that have rugged or challenging environments, encourage self-sufficiency

31
New cards

linear settlements

building and human activities are organized close to a body of water or along transportation route, are common before industrialization because of the need for fresh water to irrigate crops

32
New cards

British enclosure movement

when common land has been divided up into individually owned plots and enclosed, farmers began to experiment on these plots causing for increased productivity for profit, caused many farmers to go to factory jobs instead

33
New cards

metes and bounds systems

method of measuring and describing land, typically using geographic landmarks, often refers to a specific point, began in england

characterization of the second agricultural revolution (4)

42
New cards

steel plow

reduced human labor, increased ability to break through the ground, led to increase in the size of farms

43
New cards

47
New cards

48
New cards

few but larger farms led to an in increase in food production led to increase in food supply led to better diets because of access to a variety of foods led to increased life expectancies led to increased population

describe what industrialization and the 2nd agricultural revolution led to overall (6)

49
New cards

green revolution struggles in africa

did not have transportation, diversity of soils made it costly to develop fertilizers, crops specific to this area were not always included in research

50
New cards

the cost to spend, cost of land and labor

two economic considerations that influence farmers decisions

51
New cards

bid-rent theory

The cost of land is higher closer to urban markets, those who purchase land near urban areas will need to do intensive farming for profit

52
New cards

paddy rice farming, truck farming, factory farming, aquaculture

intensive farming practices (4)

53
New cards

paddy rice farming

Uses terraced field, because using machines in these areas is challenging this is labor intensive, common in south asia, southeast asia, and east asia

57
New cards

monoculture

Only one crop is grown, or one type of animal is raised, per season on a piece of land

58
New cards

monocropping

The practice of only growing one type of crop or raising one type of animal year after year, farmers maximize efficiency by purchasing irrigation systems, fertilizers, and pesticides

59
New cards

lower costs of production, higher yields, more profits

positives of monocropping (3)

60
New cards

soil depletion, increased reliance on pesticides and fertilizers, increased economic risk since they are only relying on one crop

negative impacts of monocropping (3)

New cards

farming is for a profit, only one Market and transportation within a region, isotropic plain, farmers pay for transportation, beyond farmland is wilderness

von thunen beliefs (6)

72

73
New cards

salinization

high salt content

74
New cards

soil salinization

high salt content in oil, resulting from water that is used for plants, often caused by improper use of irrigation, results in lower crop yields or unusable soils

desertification

the process of fertile land becoming infertile, can be caused by agricultural practice which alter vegetation and areas

76
New cards

terrace farming

farmers build a series of steps into the side of a hill to create more space for fields one of the earliest forms of landscape alteration by humans for agriculture, increases arable land, less soil erosion, natural collection of water
