Abstract
Bamboo forms an important
component in the traditional landscape of North East India. 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 using a log linear model. The culm density of
the stand was 8950 culms ha-1 during 2005 of which 67% of growing
stock was represented by Bambusa cacharensis, 17.88%by Bambusa vulgaris and 15.12% by Bambusa balcooa. Above ground stand biomass was 121.51 t ha-1 of which 86% was contributed by culm component
followed by branch (10%) and leaf (4%). With respect to species, B. Cacharensis made up to 46% of total stand biomass followed by B. vulgaris (28%) and B. balcooa (26%). Carbon storage in the
above ground biomass was 61.05 t ha-1.
Allocation of C was more in culm components (53.05 t ha-1) than in branch (5.81 t ha-1) and leaf (2.19 t ha-1).
Carbon storage in the litter floor mass was 2.40 t ha-1, of which leaf litter made up the highest amount
(1.37 t ha-1) followed by sheath (0.86 t ha-1) and branch (0.17 t ha-1).
Carbon stock in the soil up to 30 cm depth was 57.3 t ha-1. Gross C stock in the plantation was estimated to
be 120.75 t ha-1. Carbon storage estimated in the bamboo stand of
present study offers insights into the opportunity of village bamboos in the
rural landscape for carbon storage through carbon sequestration. Management and
utilization of village bamboos as a potential source of carbon sink by
smallholder farmers are discussed in the context of their livelihood security
and the Millennium Development Goals of the United Nations.
