When animals are tamed and used for food and profit.
First Agricultural Revolution
Dating back 10,000 years, the First Agricultural Revolution achieved plant domestication and animal domestication

Second Agricultural Revolution
tools and equipment were modified, methods of soil preparation, fertilization, crop care, and harvesting improved the general organization of agriculture made more efficient
a form of subsistence agriculture in which people shift activity from one field to another; each field is used for crops for a relatively few years and left uncultivated for a relatively long period
farming that provides for the basic needs of the farmer without surpluses for marketing
Third Agricultural Revolution
Currently in progress, the Third Agricultural Revolution has as its principal orientation the development of Genetically Modified Organisms (GMO's)
the patterns described in von thunen's agricultural model (the rings)
patterns of settlement and land use that delineates property lines
characterized by a lower density of population and the wide spacing of individual homesteads.
a reigion in which the housing stock predominantly reflects styles of building that particular to the culture of the people who have long inhabited the area

Approach adopted along the eastern seaboard, in which natural features were used to demarcate irregular parcels of land
a compact closely packed settlement sharply demarcated from adjoining farmland

a community of people smaller than a town
framework consisting of stakes interwoven with branches to form a fence
a large-scale farming enterprise

The growing of crops for sale-farms are large and use modern technolgy
the introduction of pesticides and high-yield grains and better management during the 1960s and 1970s which greatly increased agricultural productivity
Non-subsistence crops such as tea, cacao, coffee, and tobacco
crops produced without the use of synthetic or industrially produced pesticides and fertilizers
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
