Earth’s climate is already facing serious irreversible alterations due to anthropogenic emissions of greenhouse gases. This paper article provides an overview of the relationship between forest depletion and its relation to above- ground biomass, leading to its harsh consequences and threatened ecosystem. Dimapur District of Nagaland is one such example of north-east India, where forested areas is aare readily contracting. The district of Dimapur has the least forest- covered area in Nagaland, according to 2011 status. The reason of for the decrease in biomass is the human exploitation, which includes the culture of shifting cultivation, and jhumming, therefore leading to devastating effects on life structure. GIS and rRemote sSensing haves emerged as an extraordinary technologextraordinary technologyy for generating worldwide scientific information and identifying different geo-environmental issues. Normalized Difference Vegetation Index (NDVI) was applied to decide determine diminishing patterns of forest in 20 years’ time stretch with interval of a decade. Vegetation density can be estimated using an index called Normalized Difference Vegetation Index (NDVI) that involves spectral information from Near Infrared and Red spectral wavelength bands. Results show a constant decrease in forest with every preceding year. In year 1990 the vegetation cover of the area is measured to be 634.272 km2, in the year 2010, 574.44 km2, and in the year 2020 it has shrunk to 510.31 km2, resulting to a decrease of 22% during 1990-–2020. With the transparent decrease of greenery, it is evident that the biomass and carbon sequestered in forests have decreased. Almost 42% of above ground biomass has lowered directly indicating of climate change. If the matter notwere investigated the matter, the temperature of the region would increase by 3 °C. Nagaland forests are primarily subjected to anthropogenic interferences. Protection and sustainable use of our ecosystem from degradation is a major aspect of development, as concluded.
