Agriculture : Chapter 8 Flashcards
Swidden cultivation
type of agriculture characterized by land rotation in which temporary clearings are used for several years and then abandoned to be replaced by new clearings;
also known as slash and burn agriculture
shifting cultivation
based on growing crops in different fields on a rotating basis;
example is Maya in Yucatan growing maize by rotating fields on a seven year cycle
paddy rice farming
the cultivation of rice on a paddy, or small flooded field enclosed by mud dikes, practiced in the humid areas of the Far East;
typically only 3 acres and is adequate to support a family because irrigated rice provides a very large output of food per unit of land
market gardening
farming devoted to specialized fruit, vegetable, or vine crops for sale rather than consumption
suitcase farming
in American commercial grain agriculture, a farm on which no one lives;
planting and harvesting are done by hired migratory crews
dairying
specialized production of dairy goods;
dairy belts near large urban areas usually produce milk and those further away produce utter, cheese, or processed milk
domesticated plant
plant deliberately planted and tended by humans that is genetically distinct from its wild ancestors as a result of selective breeding
Carl Sauer
defined cultural landscape as an area fashioned from nature by a cultural group;
combination of cultural features such as language and religion, economic features such as agriculture and industry, and physical features such as climate and vegetation
indigenous technical knowledge
highly localized knowledge about environmental conditions and sustainable land-use practices
green revolution
recent introduction of high-yield hybrid crops and chemical fertilizers and pesticides into traditional Asian agricultural systems, most notably paddy rice farming, with attendant increases in production and ecological damage
von Thunen
developed the core-periphery model to explain the distribution and intensity of agriculture based on distance to the market;
perishable foods are closest to the market;
land closest to the market is taxed more heavily and requires greater intensity
market gardens and feedlots are closest, followed by dairying, livestock fattening, grain farming, livestock ranching
cool chain
the refrigeration and transport technologies that allow for the distribution of perishables
monoculture
raising of only one crop on a huge tract of land in agribusiness
intensive culture
system of agriculture using large amounts of labor and capital for each unit of land;
results in significantly higher crop yields;
extensive culture
system of agriculture that uses small amount of labor and capital for each unit of land;
requires large amounts of land
