Sustainable agriculture is the method of growing crops by using the technique without harming the environment. Slash and burn farming is not a sustainable agriculture technique as they increase the air pollution by release a large amount of carbon dioxide.

Shift cultivation is a type of agricultural method in which farmer clears the land by burning forest and cultivate that land for short period of time. Once the soil becomes infertile farmer again clear the another land for cultivation. It is also called as jhum cultivation.

Jhum (Shifting) cultivation is a primitive practice of cultivation in States of North Eastern Hill Region of India and people involved in such cultivation is called Jhumia. The practice involves clearing vegetative/forest cover on land/slopes of hills, drying and burning it before the onset of monsoon and cropping on it thereafter. After harvest, this land is left fallow and vegetative regeneration is allowed on it till the plot becomes reusable for the same purpose in a cycle. Meanwhile, the process is repeated in a new plot designated for Jhum cultivation during next year. Initially, when the Jhum cycle was long and ranged from 20 to 30 years, the process worked well.

Shifting cultivation, also known as the slash and burn agriculture (or Jhum cultivation), is the process of growing crops by first clearing the land of trees and vegetation and burning them thereafter. The burnt soil contains potash which increases the nutrient content of the soil. This burnt land is left for 5-8 years, so as to give the soil the time to regain its fertility . It was practised by the nomads in the north- eastern states of India .

Taungya is a system whereby villagers & sometimes forest plantation workers are given the right to cultivate agricultural crops during the early stages of forest plantation establishment

The three main types of pollution are 1. Air Pollution 2. Water Pollution 3. Soil Pollution. Rapid urbanization, with the consequent increase in population and building construction, has resulted in the reduction of land for the wastes to be disposed of.
