Abstract

The rate of biomass accumulation and carbon stocks of 13 different clones of Teak in Odisha were studied to identify the promising genotypes suitable for massive clonal plantations in Odisha. ORANP2 produced highest biomass among the 13 clones of teak i.e. 223.72m3/ha, while ORANP1 registered lowest value of 64.05m3/ha in regards to biomass accumulation. The total carbon stock values were found in the range of 32.02-111.86t/ha for 13 different clones of teak. The Mean Annual Increment (MAI) value for total tree biomass lies between 1.91t/ha to 4.76t/ha in different clones of teak studied. Similarly the total CO2 content was evinced to be varied from 128.77 to 440.21t/ha among the clones studied. The Current Annual Increment (CAI) values for total carbon stock and carbon content varied from 0.95-2.38t/ha and 3.50-8.73t/ha with the net annual carbon storage was found to be within 2.91-8.16t/ha. ORANP2 was found to be superior one in terms of net biomass and carbon content. It was ascertained that selection of suitable teak clone is highly required to meet both economic and environmental obligations.

Highlights

Anthropogenic greenhouse gas emissions have been increasing alarmingly since the preindustrial era and is mostly driven by population growth and industrialization
Given that the Kyoto Protocol recognizes forest as one of the important carbon sinks, and research evidences suggest that trees and stands of trees sequester carbon within their main stem wood, bark, branches, foliage and roots for decades, research on different tree species to assess their carbon sequestration potential could help in prioritizing the best land use practices to ensure sustainability and benefit sharing among countries (Kyoto, 1997; Nizami, 2012: Adnan and Nizmai,2014)
Certified Emission Reductions (CERs) commonly known as carbon credits, where each unit is equivalent to the reduction of one metric tonne of CO2e helped in quantifying the role of carbon sinks such as forests or plantations

Summary

Introduction

Anthropogenic greenhouse gas emissions have been increasing alarmingly since the preindustrial era and is mostly driven by population growth and industrialization. Mitigation involves some level of co-benefits and of risks due to adverse side effects, but these risks do not involve the same possibility of severe, widespread and irreversible impacts as risks from climate change, increasing the benefits from near-term mitigation efforts (IPCC, 2015). Given that the Kyoto Protocol recognizes forest as one of the important carbon sinks, and research evidences suggest that trees and stands of trees sequester carbon within their main stem wood, bark, branches, foliage and roots for decades, research on different tree species to assess their carbon sequestration potential could help in prioritizing the best land use practices to ensure sustainability and benefit sharing among countries (Kyoto, 1997; Nizami, 2012: Adnan and Nizmai ,2014).
