The Bodos are agriculturist. They cultivate different kinds of crops like Bawa, Ashu, Sali etc. during the time of summer season.1 No doubt, the Bodos are good cultivator and they are self dependent. In this regard Rev. Sydney Endle says that the Bodos are especially skillful in the construction of irrigation canals and earth-work embankments for diverting water from river beds into their rice fields and their efforts in this direction are very largely aided by their closely ethnic organization.2 It is stated that when they proceeded and settled in the valley of Assam and some parts of North East India, they had crossed their earlier stages of life and became nomadic farmer.3 In earlier time, when they practiced Jhum or shifting cultivation they always tried to find out virgin land which could provide more productivity. With the passage of time, they gave up Jhum or shifting cultivation and started settled agriculture with ploughshare and other allied agricultural implements. However, concrete evidence has not been found so far when the practice of pre-agricultural activities and Jhum cultivation had been abandoned by the Bodos and when they have started agriculture with ploughshare and other agricultural implements. Even today the majorities of the Bodos are cultivators and inhabited in the village. Whenever the rainfall threatens to be below the average, the cultivators with their elders go to the field to bring the water to the paddy field from the nearest river.4

Shifting cultivation, locally known as jhum, is the predominant agricultural practice for most communities inhabiting the uplands of north-east India. The negative impacts of the practice on forest and biological resources, soil erosion and land degradation have been a serious concern for several decades now to administrators and planners as well as to the academic community. In the current context, the practice has undergone drastic changes and has become increasingly unviable, gradually leading to the marginalization of farmers practising it. Although shifting cultivation in this area has been the focus of intensive studies, particularly in terms of the underlying ecological dynamics, few have attempted to analyse the factors contributing to the marginalization of the practice. This paper examines micro-scale issues that contribute to reducing productivity (and hence marginalization), and which are of immediate concern to the shifting cultivator. The paper focuses on fundamental issues influencing the reduction in fallow cycle lengths, the impact of rural–urban migration on labour requirements for agriculture, the consequences of inadequate employment and cash generation facilities on labour availability and crop productivity, as well as government efforts to promote agricultural productivity in these areas. The main focus of the paper is on the impact of each of these factors and their synergystic effect on the marginalization of shifting cultivation.

Due to shifting cultivation, the overall structure and composition of ecological condition is affected, hence landscape study becomes important for maintaining ecological diversity and appropriate scientific planning of any area. Garo hills region of northeast India is suffering from Geomorphological risk like sheet erosion, landslide etc. due to the age old tradition of shifting cultivation in the fragile hill slopes aided by other anthropogenic activities. The present study was conducted to examine the role of shifting cultivation for deforestation and degradation with variant of slope and elevation to relate vegetation cover with slope and elevation in the Garo Hills landscape of Meghalaya using temporal remote sensing data of 1991, 2001 and 2010. It revealed that there is decrease in dense forest and open forest during the 1st decade while areas under dense forest and non-forest increased in 2nd decade. This increased forest area is confined in the high slopes, which are inaccessible. The study shows increase in shifting cultivation near-about double fold in high slope and more than a double fold in the high altitudinal area in last decade, which is negative sign in terms of Geomorphological protection.
