SHIFTING AGRICULTURE

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. Shifting agriculture is a system in which plots of land are cultivated temporarily, then abandoned and allowed to revert to their natural vegetation while the cultivator moves on to another plot. In shifting agriculture, the period of cultivation is usually terminated when the soil shows signs of exhaustion or, when the field is overrun by weeds. In shifting agriculture the length of time that a field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow. Shifting Agriculture technique is often used in Less Economically Developed Countries. In shifting agriculture, cultivators use a practice of slash-and-burn as one element of their farming cycle. In shifting agriculture, after two or three years of producing vegetable and grain crops on cleared land, the migrants abandon it for another plot.

Shifting agriculture and sustainable development: an interdisciplinary study from north-eastern India. - Ramakrishnan, P. S., School of Environmental Sciences, Jawaharlal Nehru University, New Delhi. Abstract: This book presents a wide ranging synthesis of a long-term ecological study of shifting cultivation in upland NE India (Meghalaya and Arunachal Pradesh), supported by India-MAB, the Department of Environment and Forests, the Department of Science and Technology, the University Grants Commission and other national institutions. 

SOCIAL STRUCTURE AND SHIFTING AGRICULTURE OF THE WHITE MEO. George A. Binney. Abstract: 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, and the hamlets, located on mountain ridges, average 7 to 35 households.

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. Abstract: 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.

Human-environmental influences and interactions in shifting agriculture when farmers form expectations rationally - D W Jones, R V O'Neill - Environment and Planning A 25(1) 121–136. Abstract. 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. Farmers are 'given' a model of expectations formation in which the expected future value of variables interact in the same manner as in the current period. Several salient characteristics commonly attributed to shifting, or rotational, agriculture are replicated. Higher crop prices and increased population shorten fallow periods. Those same changes also increase the total area of land under shifting agriculture.

Impacts of shifting agriculture on a floodplain woodland regeneration in dryland, Kenya. G. Oba, Noragric, N. C. Stensethb and R. B. Weladjic, The Agricultural University of Norway.
Abstract: 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 sorghum farming cycles through woodland regeneration was closely associated with forest landscapes that were used for livestock browsing. The study shows the positive role played by shifting agriculture in forest regeneration, implying that farming promoted ecosystem diversity.
