Abstract
Quantification of carbon stock and
development of country-specific emission
factors in relation to the Agriculture,
Forestry, and Other Land Use (AFOLU)
sector has the potential to improve national
greenhouse gas inventory systems. This
study was therefore, conducted to quantify
soil organic carbon (SOC) and develop
emission factors using the national forest
inventory data of Tanzania. The results,
showed that, the mean SOC for the different
land cover subclasses ranged from 31.23 Mg
C /ha to 99.8 Mg C /ha. The lowest value
being recorded in the bushland thicket and
highest value in the forest humid mountains.
Spatial interpolation map indicated that,
large areas in the central part had low values
of SOC, ranging from 0-53Mg C/ha. The
SOC for the primary land cover classes were
37.32 Mg C/ha, 43.44 Mg C/ha, 39.68 Mg
C/ha for forest, non-non forest and wetlands
respectively. Their correspondingly annual
emission factors were, 3.56 Mg CO2/ha/yr,
4.14 Mg CO2/ha/yr, and 3.78 Mg CO2/ha/yr,
respectively. The values presented in this
paper correspond to IPCC tier 2 and can be
used for estimation of carbon emission at the
national scale for the respective major
primary land cover classes.
