A Novel Approach To Understand The Spatial And Temporal Pattern Of Shifting Cultivation Fields Using GIS Techniques In Longding Division Of Arunachal Pradesh, India
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Shifting cultivation, locally known as jhum, is one of the dominant traditional land use system practiced in the uplands of the hilly states of the northeastern region of India, but there is lack of information on the spatial and temporal dynamics of shifting cultivation landscapes. Some reports are available on the temporal extend of jhum cultivation from few districts intermittently apart from the national level land use land cover and wastelands atlas, but an exhaustive analysis over a long period has not been attempted. In order to generate information on the prevailing jhum cycles and their dynamics in the region, a study was conducted in Longding division of Arunachal Pradesh employing geospatial techniques based on spatio-temporal analysis of time series Landsat data and spatial overlay techniques to identify the jhum cycles. The results revealed that jhum cycle of 9-11 years was found out to be the dominant jhum cycle in the division and the cycle <8 years comprises of only 10% and >9 years dominated (90%) the area. Further, the study found that an average of 37.96 km2 was cleared annually for jhum affecting an area of 420.54 km2 (46.28%) of forest area during the span of 16 years period i.e. 2000-2015.
