Our study analysed LULC changes between 1998 and 2018 in the East and South districts of Sikkim using multispectral Landsat imagery (Landsat 5 TM and Landsat 8 OLI/TIRS). We applied supervised classification with the Maximum Likelihood Classifier (MLC) and employed post-classification change detection techniques. The findings showed that built-up areas mainly expanded at the expense of agricultural land and vegetation, underscoring the unsustainable trajectory of the ongoing land use patterns. With these findings, we strongly recommend a sustainable planning of future developmental activities by encouraging traditional agricultural and responsible land use practices, while conserving the rich regional biodiversity.
