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.

Impacts of shifting agriculture on a floodplain woodland regeneration in dryland, Kenya
G. Oba, Noragric, N. C. Stensethb and R. B. Weladjic.
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 regeneration.

Sustainability Appraisal of Shifting Cultivation in the Chittagong Hill Tracts of Bangladesh
Ole K. Borggaard, Abdul Gafur, Leif Petersen, AMBIO: A Journal of the Human Environment 32(2): 2003.
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 3–5 years and lack of land rights.

The particular communities which are discussed in this paper are located in the Hong Dong and Chom Thong districts of Chiengmai Province. In this region, settlements of more than 40 households are rare.
