Agricultural Development
Agriculture Overview - Resources
Agriculture has developed over thousands of years. From the first agricultural revolution to modern genetic modification of plants.
Slash & Burn
Slash and burn agriculture is the process of cutting down the vegetation in a particular plot of land, setting fire to the remaining foliage, and using the ashes to provide nutrients to the soil for use of planting food crops. (Courtesy of Geography.about.com)
Commercial/mechanized Farming
Cereals: crops where the seeds are the main product e.g. wheat, corn. Commercial Farming: farming for a profit, where food is produced by advanced technological means for sale in the market. Often very few workers are employed. (See Subsistence Farming). (Courtesy of Geography.about.com)
Plantations
A plantation is a large piece of land (or water) usually in a tropical or semitropical area where one crop is specifically planted for widespread commercial sale and usually tended by resident laborers. (Courtesy of Google.com)

Terracing
This type of landscaping, therefore, is called terracing. Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields both decrease erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. (Courtesy of google.com)
Ranching
A ranch is a type of farm and an area of landscape, including various structures, given primarily to the practice of ranching, the practice of raising grazing livestock such as cattle or sheep for meat or wool. (Courtesy of google.com)
Intensive Farming
Intensive farming or intensive agriculture is a kind of agriculture where a lot of capital and labour are used to increase the yield that can be obtained per area. The use of large amounts of pesticides for crops and of medication for animal stocks is common. (google.com)

Subsistence Farming
Subsistence agriculture is self-sufficiency farming in which the farmers focus on growing enough food to feed themselves and their families. The typical subsistence farm has a range of crops and animals needed by the family to feed and clothe themselves during the year. (Courtesy of google.com)
Nomadic Herding
Nomadic herding is a subsistence practice type of grazing. People raise animals for their own food and move them from place to place to areas of available pasture. Nomadic herding still exists in the world today in the areas of Northwest Asia, the Middle East, North Africa and the Arctic Tundra. (Courtesy of google.com)
Genetically Modified Organisms (GMO's)
When a gene from one organism is purposely moved to improve or change another organism in a laboratory, the result is a genetically modified organism (GMO). It is also sometimes called "transgenic" for transfer of genes. There are different ways of moving genes to produce desirable traits. (google.com)
