Shifting Cultivation

Afforestation is an example of cultivated land, self-sufficiency, large scale agriculture. It is a traditional agricultural form of tropical rainforest. This case study will focus on South American Amazon Indians

The tribal Indians of Kicha and Kayapo tidied up a narrow area of ​​vegetation. Ash is divided into aseptic soil to supply nutrients, then they burn it. Before the Indians move to another part of the tropical rainforest, the land will propagate for 2 to 3 years thereafter. This will allow the rainforest area to recover

The relationship between cultivation period and fallow period is important for the stability of the transplant system. These parameters determine whether the entire transplant system suffers net loss of nutrient over time. Unless measures are taken to stop the loss, the system of net loss of nutrients in each cycle will ultimately lead to resource degradation. In some cases, soil may be irreversibly depleted within 10 years (including erosion and reduction of nutrients).

For thousands of years, and to this day indigenous peoples of the Amazon River have traditionally changed their habitat and forest habitat. In the Amazon and other tropical regions of the world, people often find transfer plants. The moving cultivation system is designed to adapt to the soil and climate characteristics of the Amazon basin - low soil fertility, high precipitation and fast leaching nutrition

Transfer planting is a type of agriculture or planting system where a small number of "fields" are planted at any given time, most of which are in different stages of natural regeneration. As time goes on, the fields are cultivated for a relatively short period of time, they can be restored for a relatively long time or become friends. Eventually, previously cultivated fields will be cleared of natural vegetation and planted again in crops. Fields of established and stable crop cultivation systems are cultivated on a regular basis and are falling down. This type of agriculture is called jamming in India.

The secondary forest made by rotation is abundant in plants and animals resources than humans, but biodiversity is much lower. Mobile farmers regard forests as agricultural landscapes at all stages of the normal cycle. Those who are not used to living in the forest do not see the fields of the trees. Instead, they consider chaotic landscapes where trees seem to be randomly harvested and burnt so that they can plant or shoot short or "agricultural", "primitive" and progressive It changes to a stage. The transfer of agriculture is not so. Stable crop cultivation systems vary widely, adapt to the microenvironment, and are carefully managed by farmers during planting and fallowing. The assigning farmer may have knowledge of highly developed knowledge and the local environment, the crops they use and the conventional plant species.
