Shifting cultivation is an agricultural system in which a person uses a piece of land, only to abandon or alter the initial use a short time later.
This system often involves clearing of a piece of land followed by several years of wood harvesting or farming until the soil loses fertility.
Once the land becomes inadequate for crop production, it is left to be reclaimed by natural vegetation, or sometimes converted to a different long term cyclical farming practice.
disadvantages
It can easily lead to deforestation because when soil fertility is exhausted, farmers move on and clear another small area of the forest
Shift farming can easily cause soil erosion and desertification
It destroys water sheds
Shift farming is uneconomical
It easily leads to loss of biodiversity
Water pollution in coastal areas easily occur because of raw sewage and oil residue
Shifting mode of farming restricts the intensity of land use
I hope it will help you ☺️
