This research aimed to quantify the carbon stock of aboveground living vegetation in silvopastoral
systems of natural regeneration practiced by family farmers in the settlement project Belo Horizonte
II. The settlement is located in São Domingos do Araguaia – PA and the SSP managed from the
natural regeneration of tree species constitutes an alternative for the integration of socioeconomic
and environmental objectives, seeking sustainability for family farming in Southeast Pará. The
biomass of the arboreal component was obtained from data from the field evaluation carried out in
December 2009. The arboreal biomass per hectare was estimated from of calculation: BA =
(ΣBA/1000) x (10000/plot area) and the carbon stock was estimated from ΔCBA = (BA x CF),
where: ΔCBA = amount of carbon in aboveground living biomass (t C/ha); BA = aboveground
living woody biomass (t DM/ha); CF = is the carbon fraction (t C /t MS) which, according to the
IPCC (Intergovernmental Panel on Climate Change), defaults to 0.5. The carbon stock in the
aboveground living biomass was 14.08 t C/ha, being 0.27 C t/ha and 13.81 t C/ha for the woody and
non-tree vegetation biomass, respectively. |
