ABSTRACT

Carbon subsists as carbon dioxide and represents about 0.04% in the earth’s atmosphere. It has acquired a lot of consideration as a greenhouse gas, due to it has possible impact on the climate of the world. Various anthropogenic activities has increased the carbon level in the atmosphere and interrupted the carbon cycle. However, environment has it’s possess system of storing and sequestering the carbon in its “sinks’’ or “reservoirs”. Forest plays a unique role in carbon sequestration as well as mitigating the climate change. Assessment of forest carbon stocks depends upon the assessment of forest biomass. The Intergovernmental Panel on Climate Change (IPCC) recognized total five carbon pools for the terrestrial ecosystem concerning biomass, namely the below-ground biomass, above-ground biomass, woody debris, litter and soil organic matter. The above-ground biomass comprises the major portion among the all carbon pools. The paper gives detail about the traditional methods as well as their limitations. Because of the limitations of traditional methods to measure biomass of forest, generally remote sensing has been utilized for estimation of biomass of the forest in the past decade. Geo-spatial technologies like Remote Sensing (RS) and Geographic Information Systems (GIS) provides rapid assessment of above ground biomass (AGB) and terrestrial carbon stock (CS) over large areas comparatively at a low cost and in less time. This paper, aims to summarize and review the various techniques and studies that were used to estimate the forest biomass. Keywords: Climate change, Biomass estimation, Remote sensing, GIS, Carbon stock
