This book brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Some critics have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to. 3. Shifting cultivation enhances bio-diversity and is crucial for in-situ conservation of crop genetic resources. Shifting cultivation is a form of land use which enhances biodiversity. Severe declines in plant diversity have been observed in most areas when shifting cultivation is replaced by permanent land use systems. ParticularlyFile Size: 1MB. Shifting cultivation is the main land-use system transforming landscapes in riverine Amazonia. Increased concentration of the human population around villages and increasing market integration during the last decades may be causing agricultural intensification. Studies have shown that agricultural intensification, i.e. higher number of swidden-fallow cycles and shorter fallow periods, reduces Cited by: CHAPTER: 1 – INTRODUCTION Introduction Shifting cultivation commonly known as Jhumming is one of the most ancient system of farming believed to have originated in the Neolithic period around B.C (Borthakur, D.N. ). It is also alternatively called as Slash and Burn method of cultivation.

Mosaic landscapes under shifting cultivation, with their dynamic mix of managed and natural land covers, often fall through the cracks in remote sensing–based land cover and land use classifications, as these are unable to adequately capture such landscapes’ dynamic nature and complex spectral and spatial signatures. But information about such landscapes is urgently needed to improve the Cited by:   Shifting cultivation causes a high national waste as it converts the green land into a barren land. The land takes many years to replenish just at the cost of providing yield for 2 to 3 years. It upsets the ecological balance as it disturbs many eco-systems of that region due to . Djoube principal mode of subsistence consists of shifting cultivation and fishing. Formerly, the shifting cultivation had been done mainly in the primary forest. However at present, as the primary forest has decreased near the village, the villagers also use theCited by: 6. What are the 2 distinguishing hallmarks of shifting cultivation? 1.) farmers clear land for planting by slash and burn agriculture 2.) farmers grow crops on a cleared field for only a few years until soil nutrients are depleted and then leave it nothing planted for many years so the soil can recover.

In the study of shifting cultivation systems, fallow duration is seen as the key determinant of vegetation and soil dynamics: long fallows renew soil fertility, biomass and biodiversity. The book on ‘Shifting Cultivation and Tribal Culture of Tribes of Arunachal Pradesh, India’ has been written mainly to show how the traditional life of Tribal people of state of Arunachal Pradesh, India are very much attached to shifting cultivation. Shifting cultivation is Author: Tomo Riba. Shifting cultivation, sometimes called swidden or slash and burn, is commonly found throughout the Amazon and other tropical regions worldwide. Shifting cultivation systems are designed to adapt to the soil and climatic characteristics of the Amazon basin- low soil fertility, high precipitation, and fast leaching of nutrients. Influence of shifting cultivation dynamics on the creation of diversity of ethnovarieties propagated as clones. The Atlantic rainforest is an area of importance for the conservation of biodiversity. Many traditional communities of peasants maintain secular agricultural by:
