What is jhum cultivation

Last updated: April 1, 2026

Quick Answer: Jhum cultivation is a traditional shifting cultivation or slash-and-burn agricultural practice used in Northeast India and Southeast Asia. Farmers clear forest land, cultivate crops for a few years, then move to new plots as soil fertility depletes.

Key Facts

Overview

Jhum cultivation, also known as shifting cultivation or slash-and-burn agriculture, is a traditional farming practice in Northeast India and Southeast Asia. The term 'jhum' originates from the local Khasi language of Meghalaya. This agricultural system involves clearing forest land, burning the vegetation to create ash fertilizer, cultivating crops for a limited period, and then moving to new plots while allowing old land to regenerate.

The Jhum Cycle

The traditional jhum cycle follows these steps: farmers select a forested plot, clear trees and vegetation during the dry season, burn the cut vegetation to release nutrients into soil, cultivate crops for 2-4 years until fertility declines, then move to a new plot. The abandoned land lies fallow for 8-10 years, allowing forests to regenerate and soil to recover naturally.

Geographic Distribution

Jhum cultivation is predominantly practiced in Northeast Indian states including Meghalaya, Tripura, Mizoram, Nagaland, and Manipur. Similar systems exist in Southeast Asia including Myanmar, Laos, and Thailand, where they are known by different names such as swidden or shifting agriculture.

Crops and Agricultural Patterns

Sustainability and Modern Challenges

While jhum cultivation was sustainable for centuries with small populations and long fallow periods, modern pressures have reduced its sustainability. Population growth, land scarcity, and shortened fallow periods (now 3-5 years) prevent adequate forest regeneration, leading to deforestation, soil degradation, and increased carbon emissions. Governments increasingly promote permanent agriculture and terrace farming as alternatives.

Related Questions

What crops are grown in jhum cultivation?

Common crops include hill rice, corn, millet, sorghum, and various vegetables. Legumes and tubers are cultivated as secondary crops to improve soil fertility and nutrition.

Why is jhum cultivation being phased out?

Government policies, population pressure, shortened fallow periods, and environmental concerns about deforestation have led to promotion of permanent agriculture as an alternative.

How long is the fallow period in jhum farming?

Traditionally, fallow periods last 8-10 years for forest regeneration. However, due to land pressure, periods have decreased to 3-5 years in many regions, affecting sustainability.
