Unit 5 Flashcards
Food security
Food security: physical, social, and economic access at all times to safe and nutritious food sufficient to meet dietary needs and food preferences for an active and healthy life.
Undernourishment
Undernourishment: dietary energy consumption that is continuously below that needed for a healthy life and carrying our light physical activity.
Arithmetic Density
Arithmetic density: the total number of people divided by total land area
Physiological Density
Physiological density: the total number of people per unit area of arable land
Agricultural Density
Agricultural density: the ratio of the number of farmers to the amount of arable land.
Biodiversity
Biodiversity: all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world.
Crop
Crop: any plant cultivated by people
Agriculture
Agriculture: the deliberate modification of Earth’s surface through cultivation of plants and rearing of animals to obtain sustenance or economic gain.
Agricultural Revolution First
Agricultural revolution (first): the process that began when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering.
Hunting and Gathering
Hunting and Gathering: the first way humans obtained food through.
Columbian Exchange
Columbian Exchange: the transfer of plants and animals, as well as people, culture, and technology, between the western hemisphere and Europe, as a result of European colonization and trade.
Subsistence Agriculture
Subsistence agriculture: (found in developing countries) is the production of food primarily for consumption by the farmer’s family.
Commercial Agriculture
Commercial agriculture: (found in developed countries) the production of cash crops primarily for sale off the farm.
Cash Crop
Cash crop: one that is grown for sale, rather than for the farmer’s own use.
Agribuisness
Agribusiness: the set of economic and political relationships that organize food production for commercial purposes.
Economy of Scale
Economy of Scale: cost advantages reaped by companies when production becomes efficient
Vegetative Planting
Vegetative Planting: reproduction of plants by direct cloning from existing plants
Seed Agriculture
Seed agriculture: reproduction of plants through annual planting of seeds that result from sexual fertilization.
Long Lots
Long Lots: long, narrow land divisions for farming, usually lined up along a waterway
Metes and Bounds
Metes and Bounds: the boundaries of a parcel of real estate that are identified by its natural landmarks. Often used as the “legal description” of the land
Township and Range
Township and Range: Townships are rectangular blocks of land about 6 miles square. The squares are gridded and numbered according to their position north or south of the baseline.
Intensive Subsistence agriculture
Intensive subsistence agriculture: a form of subsistence agriculture characteristic of Asia’s major population concentrations in which farmers must expand a relatively large amount of effort to produce the maximum possible yield from a parcel of land.
Intertillage
Intertillage: Tillage between rows of crops
Double Cropping
Double cropping: Harvesting twice a year from the same field
Crop rotation
Crop rotation: The practice of rotating use of different fields from crop to crop each year to avoid exhausting the soil.
Wet Rice
Wet rice: Rice planted on dry land in a nursery and then moved to a deliberately flooded field to promote growth
Sawah (Paddy)
Sawah (Paddy): an irrigated, or flooded, field used to grow rice.
Threshed
Threshed: to beat out grain from stalks by trampling it.
Winnowed
Winnowed: To remove chaff by allowing it to be blown away by the wind
