Why shifting agriculture harmful for the environment?​

Answer 1

Yes it is harmful for the environmentbecause trees and leaves are burnt and their ash is added to the soil to increase fertility and after certain period of time the land gets abandoned and looses all its fertility and no crops can be grown on it. SoShifting Cultivation is harmful for the environment.

Answer 2

Shifting cultivation is an important form of primitive agricultural land use.

In this system forest area is cleared by slash and burn techniques. Till 1950’s shifting

cultivation, under its diverse forms of slash-and-burn system was a traditional method

of cultivating tropical highland and mountain soils, mostly for providing a minimum

subsistence to the peasantry (Jasbir Singh, 1997). For primitive cultures, the

cultivation was a remarkable innovation which is based on the revolutionary transition

from forest based food gathering to agriculture based food production. The cycle of

rotation was also long having enough time to regenerate the soil. This is how a

nomadic cropping system for self-sufficient subsistence economy developed with

labour efficient systems.

In course of time, various adverse effects arise due to cultivation of Jhum.

With the increasing population, more pressure on land increased with shorter Jhum

cycles. Short fallow periods are no longer adequate to restore the soil productive

capacity therefore, decline in crops yield arise. With the increase in population

pressure on the land and the Jhum cycle decreased. The main reason behind the

persistency of this system of cultivation lies in its compatibility with the physical

environment.
