“…Inventory of Organic Carbon... Floresta e Ambiente 2019; 26(4): e20160426 that indicated by the Intergovernmental Panel on Climate Change (Eggleston et al, 2006), which suggests 37% for the litter. Torres et al (2013) observed an average of 52% of C content in the litter in a Semi-Deciduous Seasonal Forest in Minas Gerais. On the other hand, Higuchi & Carvalho (1994), in a Tropical Forest in the Amazon Region, and Morais et al (2017), in the Cerrado vegetation of the state of Minas Gerais, found mean C contents in the litter of 39% and 44%, respectively.…”

Carbon binding capacity varies between forest plantations, mainly in terms of species and climate and soil conditions. The objective of this study was to estimate the amount of organic carbon stored in aerial tree biomass in the litter and soil of a homogeneous planting of Pterogyne nitens Tul. located in the Southwest Bahia region of Brazil. The woody biomass was obtained by destructive method. Litter collection was carried out using a wooden template (0.25 m 2 ). Soil samples were collected at four depths (0-5, 5-10, 10-20 and 20-40 cm). The carbon stored in all studied compartments totaled 47.1 Mg ha -1 with a greater contribution from the ground (31.4 t ha -1 ). The accumulated litter was the lowest carbon compartment, storing about 1.4% of the total. Among the different fractions of the biomass, the stem is the largest carbon reservoir, representing about 46% of fixed C biomass.

RESUMOA preocupação mundial acerca das mudanças climáticas motivou a elaboração de um compromisso climático, na Conferência das Partes 21 em Paris no ano de 2015. O Acordo de Paris, o qual o Brasil é signatário, prevê limitar a elevação da temperatura média do planeta em 2ºC em relação aos níveis pré-industriais. Os sistemas silvipastoris (SSP) são uma atividade incentivada pelo governo brasileiro, com potencial de mitigação estimado em 0,1360 MgC ha-1 ano-1. Dessa forma, o objetivo do presente estudo é realizar uma revisão bibliográfica sobre o potencial de estocagem e incremento de carbono em diferentes sistemas silvipastoris no Brasil, e comparar esses valores com a meta proposta na pelo país no Acordo de Paris. Para elaboração desse estudo foram levantados dados de SSP com diferentes idades, arranjos espaciais e espécies, localizados em diferentes regiões do país. O incremento médio anual em carbono encontrado nos diferentes SSP avaliados foi de 4,5613 MgC ha-1 ano-1. Esse valor é superior ao estimado pelo governo brasileiro para cumprir a sua meta de redução de emissões de gases de efeito estufa. Foi possível concluir que os SSP contribuem para a remoção de CO2 atmosférico e, portanto, devem ser incentivados para mitigação das mudanças climáticas.Palavras chave: Acordo de Paris, Integração lavoura pecuária floresta, Programa agricultura de baixo carbono. ABSTRACTGlobal concern about climate change has prompted a climate commitment at the Conference of Parties in Paris in 2015. The Paris Agreement, which Brazil is a signatory, plans to limit the rise in the planet's average temperature by 2ºC in relation to pre-industrial levels. Silvopastoral systems (SSP) are an activity encouraged by the Brazilian government, with mitigation potential estimated at 0.1360 MgC ha-1 year -1. Thus, our objective is to carry out a literature review on the potential of storage and increase of carbon in different silvipastoral systems in Brazil, and to compare these values with the goal proposed by the country in the Paris Agreement. For the preparation of this study, we performed the data collection of SSP with different ages, spatial arrangements and species, located in different regions of the country. The average annual increase in carbon found in the different SSPs evaluated was 4.5613 MgC ha-1 year -1. This figure is higher than that estimated by the Brazilian government to meet its goal of reducing greenhouse gas emissions. It was possible to conclude that SSPs contribute to the removal of atmospheric CO2 and, therefore, should be encouraged to mitigate climate change.Keywords: Agreement of Paris, Integration crop livestock and forest, Low carbon agriculture program. INTRODUÇÃOO aumento nas emissões de gases de efeito estufa (GEE) na atmosfera em virtude das atividades humanas, e seus efeitos nas condições climáticas do planeta se tornaram um desafio para a população mundial (MONDANI et al., 2017).

“…Various disturbances have occurred over the years in the forest fragment, including the extraction of wood and planting of agricultural cultivars and of eucalypt (Torres et al, 2013). Regeneration of the native vegetation in the area has been underway however, for approximately 25 years.…”

“…For this, three trees from each species were selected as well as by diameter class for the partial analysis of the trunk, which corresponds to the removal of a wood sample at a height of 1.30 m, with the help of increment borers (Torres et al, 2017). The material was then taken to the laboratory where part of it was used to determine the basic wood density for each species, according to the methodology described by Vital (1984) andNBR 11941 (ABNT, 2003), and the other part submitted to complete calcination in an muffle furnace to determine the carbon content, according to the methodology described by Torres et al (2013).…”

Growth and yield modeling at the diameter distribution level is an important tool to understand forest dynamics and to predict whether a forest will act as a CO2 emissions source or sink. Therefore, the objective of the present study was to determine the diameter distribution and carbon stock of a forest fragment using the Markov chain to evaluate the impact of growth dynamics on forest carbon capture. Twenty plots of 10x50m were inventoried, between 2010 and 2015, counting the stems with dbh > 5 cm. Diameter distribution was projected for 2015 and 2020, considering the whole fragment and the ecological groups (pioneer and non-pioneer tree species). The volume was determined using allometric equation while biomass and carbon was determined by multiplying the volume by the basic wood density and the carbon content, respectively. The diameter distribution estimated for the fragment and ecological groups did not differ statistically from the values observed using the Kolmogorov-Smirnov test (p-value < 0.05). The number of stems ha-1 estimated in the fragment was from 1,692 in 2015 to 1,841 in 2020. For the pioneer and non-pioneer species, the number of stems ha-1 was from 476 and 1,203 in 2015 to 472 and 1,362 in 2020, respectively. The carbon stock increased 5.69 MgC ha-1, with the greater contribution coming from the non-pioneer species. Therefore, it was concluded that the diameter distribution would remain “J-inverted” and the forest fragment would continue to act as a carbon sink over the coming years.
