Question:
What is shifting cultivation? What are its disadvantages?
Answer:
In shifting cultivation a plot of land is cleared by felling the trees and burning them. The ashes are then mixed with the soil and crops like maize, yam, potatoes and cassava are grown. After the soil loses its fertility, the land is abandoned and the cultivator moves to a new plot. In the ideal case, shifting cultivation is a cycle where farmers come back to the original place after a couple of years.
Shifting cultivation systems are primitive, backward, wasteful, unproductive, exploitative and the cause of widespread environmental degradation. Shifting cultivators are blamed for the destruction of much of the worlds tropical forests, land degradation, atmospheric pollution and global climatic change.
