agriculture
the purposeful cultivation of plants or raising of animals to produce goods for survival
topography
an area’s land features
climate regions
areas that have similar climate patterns generally based on their latitude and their location on coasts or continental interiors. characterized by a combination of temperature, precipitation, wind patterns, and topography. main five types (tropical, dry, temperate, continental, polar)
mediterranean agriculture
agriculture practiced in an area with a mediterranean climate. consists of growing hardy trees (olive, fruit, and nut trees) and raising sheep and goats (which forage in sparse, scrubby summer growth and maneuver around the region’s steep landscape)
subsistence agriculture
agriculture designed primarily to provide food for direct consumption by the farmer and the farmer's family. excess may be sold off or bartered for money. less industrialized form of farming, primarily hand labor.
commercial agriculture
a form of agriculture undertaken in order to generate products for sale off of the farm in order to make a profit. range of goods depends on geographic and economic factors.
bid-rent theory
a theory to explain how land value determines how a farmer may use the land, either intensively or extensively. (how much they buy because of high or low cost, and how productively the land is used). can also affected by ease of good transport (ex. dairy or grain)
central business district (CBD)
an area where a large amount of businesses are located (usually in a highly accessible location)
intensive agriculture
when farmers expend a great deal of effort to produce as much yield as possible from an area of land. rely on high “inputs” of energy such as chemical fertilizer, pesticides, growth regulators, human or animal labor, natural fertilizer, or soil care.
monocropping
the cultivation of one or two crops that are rotated seasonally
monoculture
the agricultural system of planting one crop or raising one type of animal annually
crop rotation
the varying of crops from year to year to allow for the restoration of valuable nutrients and the continuing productivity of the soil.
plantation agriculture
large scale commercial farming of one particular crop grown for markets often distant from the plantation (common in periphery/semi-periphery countries)
market gardening
farming that produces fruits, vegetables, and flowers and typically serves a specific market/urban area where farmers can conveniently sell to local stores, restaurants, farmers’ markets, and road stands.
mixed crop and livestock systems
in which both crops and livestock are raised for profit. two types of mixed farming: on-farm and between-farm. in on-farm mixed farming, crops and livestock are raised on the same farm. in between-farm mixing, two farmers share resources, with one growing crops and the other raising livestock.
clustered/nucleated settlement
residents live in close proximity. houses and farm buildings near one another, with farmland surrounding the settlement. promotes social unity, but can also lead to social friction or longer distance from fields.
dispersed settlement
houses and buildings isolated, distributed over a large area. often in areas with difficult terrain. promotes independence but lacks social interaction or shared institutions.
linear settlement
houses and buildings extend in a long line that usually follows a land feature (riverfront, coast, hill, transportation route)
extensive agriculture
system of crop cultivation using small amounts of labor and capital in relation to area of land being farmed.
shifting cultivation
the practice of growing crops or grazing animals on a piece of land for a year or two, then abandoning the land when the nutrients have been depleted from the soil and moving to a new piece of land where the process is repeated. the size of land is usually not large, but requires a relatively large area in which to operate over time. (is practiced in marginal areas of the tropics, like rainforests in south america, central and west africa, and southeast asia)
marginal environment
an environment that has poor soil or other undesirable characteristics. often located at the edge of deserts or other desolate areas and experiences extreme weather or climate conditions. usually far from roads and other means of transportation.
slash and burn
a type of shifting cultivation. when land is cleared by cutting down trees and brush, then leaving them to dry, and burning the “slash”, turning it into a nutrient-rich ash fertilizer. the area is cultivated until the soil becomes infertile, and the process is repeated. has long been practiced, but is unsustainable as more farmers are adopting the practice. causes habitat loss for local creatures, increases likeliness for erosion, and releases pollution and carbon dioxide into the air, contributing to global climate change.
overgrazing
destruction of feed plants that results from livestock overpopulation or overfeeding
nomadic herding/pastoral nomadism
when farmers move their animals seasonally to allow the best grazing. requires far-reaching areas of land to prevent overgrazing
transhumance

domestication
the deliberate effort to grow plants and raise animals, making plants and animals adapt to human demands, and using selective breeding to develop desirable characteristics
foragers
small nomadic groups who had primarily plant-based diets and ate small animals or fish for protein. (plants included fruits and vegetables, seeds and nuts, tubers, and other plants.) these people fished in rivers and lakes, gathered shellfish, and used traps, stones, or projectile weapons to hunt small game. sometimes formed bands to hunt larger animals.

second agricultural revolution
a change in farming practices marked by new tools and techniques that diffused from Britain and the Low Countries starting in the early 18th century. caused improvements in crop yields and changed farm organization.
enclosure system
a system in which communal lands were replaced by farms owned by individuals and use of the land was restricted to the owner or tenant who rented the land from the owner. gave farmers more control over land, creating more effective farming practices. also pushed peasants off land, creating a labor surplus that contributed to the industrial revolution.
third agricultural revolution
a shift to further mechanization in agriculture through the development of new technology and advances that began in the early 20th century and continues to present day
genetically modified organisms (GMOs)
a plant or animal with specific characteristics obtained through the manipulation of its genetic makeup. enhances ability of new strains to resist disease or drought or to have nutritional impact or consumer appeal.
green revolution
a movement beginning in the 1950s-60s in which scientists used knowledge of genetics to develop new high-yield strains of grain crops and help introduce the crop strains to semi-periphery/periphery areas with high populations and low yields. introduced by Norman Borlaug

dual agricultural economy
refers to two agricultural sectors in the same country or region that have different levels of technology and different patterns of demand. (substinence farms exist alongside commercial operations that export their crop, often to core countries) (ex. South Africa, Zimbabwe)
agribusiness
the large-scale system that includes the production, processing, and distribution of agricultural products and equipment. includes commercial farmers, food manufacturers, distributors, and marketers. controlled and dominated by larger companies.
hybrid

farm subsidies
a form of aid and insurance given by the federal government to certain farmers and agribusinesses. originally started during Great Depression in 1930s. debated on whether actually helpful or not, because family farms who need help are not receiving as much help.
tariffs
a tax or duty to be paid on a particular import or export. can affect trade between countries and bring about “trade wars” (ex. China and U.S.). used to raise government revenue, but also to protect domestic industries against foreign competition.
Von Thunen model
suggests that perishability of the product and transport costs to the market each factor into the location of agricultural land use and activity. (in to out: market, farming & dairying, forests, grain & cereal crops, livestock) based on ideal 1826 environment.
global supply chains
a system of organizations, people, technology, activities, information, and resources involved in moving a product or service from supplier to customer on a global scale.
cash crop
a crop that is produced for its commercial value. dependency on a single export can have negative consequences. if supply of cash crop is limited, specialized countries can have increased profit (ex. vanilla in Madagascar)
fair trade movement
a global campaign to fix unfair wage practices and protect the ability of farmers to earn a living. meant to improve lives of farmers in periphery/semi-periphery through improved working conditions, direct income, and insurance)
agricultural landscapes
landscapes resulting from the interactions between farming activities and a location’s natural environment.
agroecosystem
an ecosystem modified for agricultural use
deforestation
the loss of forest lands, which can lead to soil erosion. is sustainable if properly done, and on a small scale. (ex. Hin Lad Nai in Thailand for 400+ years)
terracing
the process of carving parts of a hill or mountainside into small, level growing plots. used in mountainous areas of various climates. become flooded during rainfall, but water flows through without washing away soil. preserves soil nutrients (though labor intensive). often important to cultural heritage (ex. Ifugao rice terraces in Philippines.)
reservoirs
artificial lakes created by the building of dams across streams or rivers (ex. Colorado river)
aquifers
layers of underground sand, gravel, and rocks that contain and can release useable amounts of water. (must be replenished to be sustainable)
wetlands
areas of land that are covered by or saturated with water. draining once seen as acceptable, but created habitat loss for many fish, waterfowl, and mammals. can reduce flood damage, improve water quality, and traps carbon dioxide.
desertification
a form of land degradation that occurs when soil deteriorates to a desert-like condition. can be the result of poor pastoral-nomadism in semiarid/arid lands.
biodiversity
the variety of organisms living in a location. hards can favor certain plants, reducing plant cover, and soil erosion can result when mountain slopes are compacted by livestock hooves.
salinization
the process by which water-soluble salts build up in the soil. occurs in arid/semiarid regions when water evaporates from the ground more rapidly than it is replenished by rain or irrigation. its accumulation in the root zone of a crop can lead to reduced yields.
debt-for-nature
an agreement between a bank and a peripheral country in which the bank forgives a portion of the country’s debt in exchange for local investment in conservation means.
biotechnology
the science of altering living organisms, often through genetic manipulation, to create new products for specific purposes, such as crops that resist certain pests. (ex. genetic engineering)
agricultural biodiversity
the variety and variability of plants, animals, and microorganisms that are used directly of indirectly for food and agriculture. vital to environmentally sustainable agriculture.
precision agriculture
a farming management concept that uses technology to apply inputs with pinpoint accuracy to specific parts of fields to maximize yields, reduce waste, and preserve the environment.
commodity
a raw material or primary agricultural product that can easily be sold across a large market (ex. corn, wheat, cotton) produced at similar quality, must meet minimum trade standards.
food security
reliable access to safe nutritious food that can support a healthy and active lifestyle
food insecurity
the disruption of a household’s food intake or eating patterns because of poor access to food. commonly caused by lack of money or other resources
suburbanization
the shifting of population from cities to surrounding suburbs. motivated by cheaper housing, more space, and lower crime rates
food deserts
areas where residents lack access to healthy, nutritious foods because stores selling the foods are too far away. occur in major urban areas that have more food high in cholesterol, sugar, and fat.
economy of scale
the reduced cost of producing food items as the quantity of production increases. farming on a large scale is more efficient than on a small scale.
food sovereignty
the rights of people to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agricultural systems.
empowerment
(in the context of farming) the ability to make decisions about factors such as land, livestock, seeds, fertilizer, and machinery, as well as control over finances and one’s own time.
metes and bounds
this system uses physical features of local geography along with directions and distances to define and describe boundaries of land parcels.
long-lot system
distinct regional approach to land surveying found in the Canadian Maritimes, parts of Quebec, Louisiana, and Texas whereby land is divided into narrow parcels stretching back from rivers, roads, or canals

an animal feeding operation (AFO) that concentrates large numbers of animals in relatively small and confined places, and that substitutes structures and equipment for land and labor.
milkshed
an area surrounding the milk source (dairy farm) where milk is supplied without spoiling. transportation methods will cause milksheds to vary in size
sustainable agriculture
farming methods that preserve long-term productivity of land and minimize pollution, typically by rotating soil-restoring crops with cash crops and reducing inputs of fertilizer and pesticides.
aquaculture
the name given to all farming and rearing of fish and marine plants that does not fall under the category of fishing
