Above ground biomass, production and carbon sequestration in farmer managed village bamboo grove in Assam, northeast India

摘要

Village bamboo forms an important component in the traditional landscape of North East India. Bamboos growing in the rural landscape can be the ideal choice for creating sinks for CO2. For biomass estimation of village bamboos of Barak Valley, North East India, allometric relationships were developed by harvest method describing leaf, branch and culm biomass with DBH as an independent variable. The culm density of the stand was 3380 culms ha~(-1) in 2003 and increased to 11030 culms ha~(-1) in 2006.Total above ground standing biomass of the grove was 42.98 Mg ha~(-1) in 2003 that increased to 152.15 Mg ha~(-1) in 2006 with a mean stand biomass of 99.28 Mg ha~(-1). Mean productivity of the stand was 42.5 Mg ha~(-1). Carbon storage in the above ground biomass ranged from 21.69 - 76.55 Mg ha~(-1) Current and one year old culm ages represented 58-73% (15.86-35.63 Mg ha~(-1)) of the total carbon storage in the grove. The rate of above ground carbon sequesfration was 18.93-23.55 Mg ha~(-1) with the meanof 21.36 Mg ha~(-1) Carbon storage estimated in the bamboo stand of the present study offer insight into the opportunity of village bamboos in the rural landscape for carbon storage through carbon sequestration.
