Shifting Agriculture is a system in which land is cleared
and then cultivated until it is exhausted, at which point new land is cleared and the
process restarted. Shifting Agriculture is shifting cultivation or forms of agriculture in
which an area of ground is cleared of vegetation and cultivated for a small number of
years and then abandoned for a new area. According to a Government of India report,
more than 30,000 sq km of land is under Shifting Agriculture
in the state of Orissa. The evil effects of Shifting
Agriculture are devastating and far-reaching in degrading the environment and ecology of these regions.
Human-environmental influences and interaction in shifting agriculture when farmers form
expectations rationally - D W Jones, R V O'Neill - This paper contains a study of
the response of shifting agriculture to several social and environmental changes in
circumstances in which farmers form in a relatively sophisticated manner their
expectations of the future values of key economic variables.
With this structure of expectations, the responses of the
length of fallow period, the total area of land under cultivation and lying fallow in the
initial period of a rotational cycle, and spatial structure of land rent to changes in
social and environmental parameters are examined. Characteristics attributed to shifting
agriculture are replicated. Higher crop prices and increased population shorten fallow
periods, and also increase the total area of land under shifting agriculture.
Shifting agriculture and sustainable development:
an interdisciplinary study from north-eastern India. - Ramakrishnan, P. S.
This book presents a wide ranging synthesis of a long-term ecological study of shifting
cultivation in upland NE India, supported by India-MAB, the Department of Environment and
Forests, the University Grants Commission and other national institutions. Agroecosystem
and village ecosystem function addresses: cropping yield patterns and energy budgets under
shifting cultivation; the ecological and economic efficiencies of other land use systems;
weed potential and management in shifting cultivation and other systems; and soil
fertility and nutrient budgets under shifting cultivation and other systems.

Perceptions on the role played by shifting agriculture on
ecosystems integrity at the landscape scale are divided between those proposing loss of
biodiversity and habitat fragmentation and those suggesting improvement of ecosystem
diversity. The study shows the positive role played by shifting agriculture in forest
Sustainability Appraisal of Shifting Cultivation in the Chittagong Hill Tracts of
Ole K. Borggaard, Abdul Gafur, Leif Petersen, AMBIO: A Journal of the Human Environment
An integrated socioeconomic and erosion study on the sustainability of traditional
shifting cultivation (Jhum) carried out in 1998 and 1999 in the Chittagong Hill Tracts
(CHT) of Bangladesh showed the system to be nonsustainable under the current conditions
with fallow periods of only 35 years and lack of land rights.
