What are the types of agriculture in different parts of world?
Conventional agriculture, mechanized agriculture, and finally genetically modified crops (an issue nowadays), organic farming.
Conventional agriculture has been performed for a very long time. Developing countries (some) do this type of agriculture.
Mechanized agriculture (monoculture) has been used approximately for 100 years. Instead of human workforce, mechanical tools (tractors, harvesting equipment, etc.) are used to minimize personnel need. It is ecologically problematic since monoculture tends to use lots of chemicals and oil (fuel).
Genetically modified crops (industrial) cause long term problems in terms of health and environmental concern. Many countries would like to try it since efficient is high when you use this technique.
Organic farming is another type of agriculture. Organic farming tries to be in harmony with nature.
