The growing evidence of climate change resulting from the continued increase of Green House Gases concentration in the atmosphere has made it a powerful political, social and trade issue. Now, the world is suffering from the impact of climate change on natural resources, agriculture production and so on. Hence, the reduction of Green House Gases emission and their continuously emission monitoring is essential constituent for reducing the global warming. So, to expand the forest area is the best alternative to mitigate the impact of climate change. Accordingly, the estimation of carbon sequestration rate is the crucial component for monitoring the forest carbon. Again, the present world is also talking about the REED, REED+ which also emphasis on the monitoring of forest carbon by estimating carbon stock. Hence this book provides an opportunity to share the knowledge about the calculation procedure of carbon sequestration rate of forest as in the form of biomass carbon and soil organic carbon. Furthermore, this book is useful for those researchers and organization that are involved in the estimation of biomass and soil organic and forest carbon monitoring.
