Agriculture designed primarily to provide food for direct consumption by the farmer and the farmer's family

Commercial Agriculture

Agriculture undertaken primarily to generate products for sale off the farm.

Fair Trade

Alternative to international trade that emphasizes small businesses and worker owned and democratically run cooperatives and requires employers to pay workers fair wages, permit union organizing, and comply with minimum environmental and safety standards.

An area in a developed country where healthy food is difficult to obtain

Clearing natural swamp areas to create fields

Rural settlement patterns are classified as...

Clustered, dispersed or linear

Mixed crop/ Livestock farming

Commercial farming characterized by integration of crops and livestock; most of the crops are fed to animals rather than consumed directly by humans.

First agricultural revolution

Dating back 10,000 years, the First Agricultural Revolution achieved plant domestication and animal domestication

Fertile Crescent and several other regions of the world (including the Indus River Valley, Southeast Asia, and Central America)

Mechanization

In agriculture, the replacement of human labor with technology or machines.

GMOs

Organisms that have been geneticly altered to improve their usefulnes

Local Food Movement

Produced within a fairly limited distance from where it is consumed

Plantation Agriculture

Production system based on a large estate owned by an individual, family, or corporation and organized to produce a cash crop. Almost all plantations were established within the tropics; in recent decades, many have been divided into smaller holdings or reorganized as cooperatives

Conservation

Protecting and preserving natural resources and the environment

Aquaculture

Raising marine and freshwater fish in ponds and underwater cages

Extensive agriculture

System of crop cultivation using small amounts of labor and capital in relation to area of land being farmed

Columbian Exchange

The exchange of plants, animals, diseases, and technologies between the Americas and the rest of the world following Columbus's voyages.

Sustainability

The ability to keep in existence or maintain. A sustainable ecosystem is one that can be maintained

Milkshed

The area surrounding a city from which milk is supplied.

Climate

The average weather conditions in an area over a long period of time

Urban Farming

The growing of fruits, herbs, and vegetables and raising animals in towns and cities, a process that is accompanied by many other activities such as processing and distributing food, collecting and reusing food waste.

Deforestation

The removal of trees faster than forests can replace themselves.

Market gardening

The small scale production of fruits, vegetables, and flowers as cash crops sold directly to local consumers. Distinguishable by the large diversity of crops grown on a small area of land, during a single growing season. Labor is done manually.

Von Thunen's Model

Von Thünen's model helps explain the relationship between the cost of land and the cost to transport the crop to market.
