approach to farming and ranching that avoids the use of herbicides, pesticides, growth hormones, and other synthetic inputs

genetic modification of a plant such that its reproductive success depends on human intervention
First Agricultural Revolution
Dating back 10,000 years, the First Agricultural Revolution achieved plant domestication and animal domestication.
genetic modification of an animal such that it is rendered more amenable to human control
self sufficient agriculture that is small scale and low technology & emphasizes food production for local consumption, not trade
Cultivation of crops in tropical forest clearings in which the forest vegetation has been removed by cutting and burning. These clearings are usually abandoned after a few years in favor of newly cleared forestland. Also known as slash-and-burn agriculture.
Second Agricultural Revolution
dovetailing with and benefiting from the Industrial Revolution, improved methods of cultivation, harvesting, and storage of farm produce
von Thunen Model
A model that explains the location of agricultureal activities in a commercial, profit-making economy. A process of spatial competition allocates various farming activities into rings around a central market city, with profit-earning capability the determining force in how far a crop locates from the market
Third Agricultural Revolution
Currently in progress, the Third Agricultural Revolution has as its principal orientation the development of Genetically Modified Organisms (GMO's)
The recently successful development of higher- yield, fast-growing varieties of rice and other cereals in certain developing countries, which led to increased production per unit area and a dramatic narrowing of the gap between population growth and food needs.
Genetically Modified Organisms
crops that carry new traits that have been inserted through advanced genetic engineering methods
Rectangular Survey System
Also called the Public Land Survey, the system was used by the US Land Office Survey to parcel land west of the Appalachian Mountains. The system divides land into a series of rectangular parcels.
Township and Range System
a rectangular land division scheme designed by Thomas Jefferson to disperse settlers evenly across farmlands of the US interior
Metes and Bounds System
A system of land surveying east of the Appalachian Mountains. It is a system that relies on descriptions of land ownership and natural features such as streams or trees. Because of the imprecise nature of metes and bounds surveying, the U.S. Land Office Survey abandoned the technique in favor of the rectangular survey system.
Long-Lot Survey 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
system where the eldest son in a family, or in exceptional cases, a daughter inherits all of the parent's land
term used to describe large scale farming and ranching operations that employ vast land bases, large mechanized equipment, factory-type labor fores, and the latest technoloty
Koppen Climatic Classification System
Developed by Wladimir Koppen, a system for classifying the world's climates on the basis of temperature and precipitatiion
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
the raising of domesticated animals for the produciton of meat and byproducts (leather, wool)
Specialized farming that occurs only in areas where the dry-summer Mediterranean climate prevails
