Solution:
The practice of "Swidden" agriculture is present in Asia, Africa, and S. America. Shifting farming, also known as swidden agriculture, is a historic technique used in many areas in Asia, Africa, and South America. The primary attributes of Swidden farming are as follows: Periodically, forests are chopped down and burned. In the ashes, seeds are sown after the first monsoon rains. To give the forest time to regenerate, these plots are first farmed for a few years before being left fallow for 12 to 18 years. Numerous crops are grown in these areas.
