        abstract = {In the today’s changing world, there are many major disquieting problems which have been influencing to degrade the natural resources. Degradation of vegetation cover is one of such problems. The landuse/land cover change and change in vegetation cover are mainly due to tremendous pressure on available land. To detect the change in vegetation cover of an area, the remote sensing and Geographic Information System (GIS) techniques are the best and reliable sources now-a-days. Normalized Difference Vegetation Index (NDVI) is one of vegetation indices which help to determine the spatio-temporal changes of vegetation cover. The present study tries to understand the changes of vegetation cover of Nowboicha Revenue Circle of Lakhimpur district of Assam from 2001 to 2021. Multi-temporal satellite imageries of USGS have been used for the study.  Landsat 7 ETM of 2001 and Landsat 8 OLI/TIRS of 2021 have also been used. ERDAS Imagine (9.1) and ArcGIS (10.4.1) have been used to process the data. The range of NDVI values in 2001 image from +0.56 to -0.28 and in 2021 from +0.55 to -0.11. From the study it is found that healthiest and dense vegetation cover found towards the North of the Nowboicha Revenue Circle because of the presence of Ranga reserve forest and Arunachal Himalayas. Apart from the dense forest, the maximum area of the revenue circle experienced by low vegetation cover or bare land.},
