Concept:Shifting cultivation is a traditional farming method where land is cleared by cutting and burning vegetation, then used for a few years before being abandoned.
Explanation:Farmers cut down trees and burn the dried vegetation to clear a patch of forest.
The ash enriches the soil with nutrients.
They grow crops on this land for 2 to 3 years until fertility declines.
Then they move to a new forest area and repeat the process.
The old field is left fallow to regain its natural vegetation over many years.
This practice is commonly called slash and burn cultivation because of the clearing method.
