Change Detection Analysis In Land Use Land Cover In Majuli, Assam
Abstract
The largest river island in the world, located on the Brahmaputra River course through the high countries of Assam, a state in the upper east piece of India. On a specific note, Majuliisland faces natural disasters like flooding and riverbank erosion. The
Brahmaputra waterway has overflowed the island for generations, but since the 1950’s earthquake that struck Assam's Valley of the Brahmaputra, riverbank erosion has become a problem for the area and its Majuli peoples.Enormous measure of water
and residue conveyed by the streamresults in continuous shifting of course. This river island faces massive erosion due to repeated channel movement. As a result, Majulishrunk to one-third of its original area (Sahay & Roy., 2016). This study assesses the land-use land cover changes inMajuli and the impact of spatial changes at the local level. To obtain this, we used multi-temporal remote sensing data for LANDSAT ETM 2010 and LANDSAT ETM 2020 obtained from the United States Geological Survey (USGS) and the primary data collected through fieldwork. The detection of land use change in Majuli for one decade was analysed by supervised classification, where seven land-use classes have been identified and analysed using Eradas Imagine software. The result shows changes in the agricultural land and forested area as well as built-up areas all over Majuli.
