Abstract

India is a developing country with an increasing rate of economic growth. Meanwhile, it is seen that the carbon footprint is increasing. If carbon cannot be sequestered, it is released into the atmosphere, increasing carbon footprints. Carbon was typically sequestered in the biomass of vegetation and soil in the form of soil organic matter. Cuddalore district is a significant district in Tamil Nadu. The district is in the state's Eastern Coastal Region. Natural hazards such as cyclones frequently strike this territory, causing changes in the vegetation and, consequently, the land use pattern. This affects the amount of carbon sequestered in this environment. The land use pattern in the Cuddalore district is shifting due to natural dangers and unnatural causes. The district is growing at a breakneck pace. As a result, it is critical to research carbon sequestration. The impact of land-use changes on the carbon sequestered in this area will be explored using geospatial techniques in this study work. The various land uses in this area have been categorised using GIS values for the Normalised Difference Vegetation Index (NDVI). Carbon can be sequestered in four carbon pools in each classed land use: above-ground biomass, below-ground biomass, soil organic matter, and dead organic matter. Soil organic matter is the most significant carbon sink among the four-carbon pools. Using field data, the allometric equations estimated the various carbon reservoirs (soil bulk density, tree diameter at breast height, diameter, and height of deadwood).
