RESUMO:
The degradation of tropical ecosystems caused by deforestation, selective logging and fire, results in a marked loss of biodiversity and ecosystem services, contributing to the increase in atmospheric carbon and global climate change. To reduce this and other sources of CO2 emissions into the atmosphere, the industrialized countries signed the Kyoto Protocol, where measures to reduce emissions were established, including the commercialization of carbon credits. In Brazil, which holds the greatest global biodiversity, much of the carbon stocks are maintained in protected areas, especially in indigenous lands, both in the Amazon and in the Cerrado biomes. Studies on carbon stocks and trading in indigenous areas can contribute to the economy and sustainability of these communities by generating income and protecting their natural food resources. Given this scenario, we investigated areas of cerrado and forest in Aldeia Belém (Pimentel Barbosa Indigenous Reservation), in the Amazon/Cerrado Transition, with the following objectives: 1) estimating the amount of carbon above and below the ground; 2) compare the amount of carbon with other protected areas and 3) value the carbon stock in the Indigenous Land. To this end, we established 50 plots of 10*200 m in a cerrado (savanna facies) and 10 plots of 10*100 m in a gallery forest. We collected aboveground biomass data from wood vegetation, litter, herbaceous plants and soil to estimate the carbon value of the roots. For carbon estimates in both phytophysiognomies and in the different ecosystem components evaluated, we considered the percentage of carbon as 50% of the dry biomass. To verify if the carbon accumulated in the components varied between the areas, we performed Anova Two Way Permutation. To identify which ecosystem compartment the carbon varied from between areas, we used a Kruskal-Wallis followed by a post hoc Dannett test. The carbon valuation was based on a website specialized in carbon sales, the Future Carbon Credit. The total amount of carbon per area was higher in the gallery forest (88.59 Mg ha-1) than in the cerrado (47.21 Mg ha-1) (W = 9, p <0.01), making a total of 135.8 MgC/ ha, considering the soil carbon stock of the 0-20cm layers of the two areas. The area of 1,645.64 hectares of Aldeia Belém contains approximately 398.01 Mg ha-1 of CO2 removed from the atmosphere, revealing a substantial financial potential of R$176,860.39 per hectare based on the most recent average price. The stock of areas was 47% lower than that found in other carbon preserved areas and total income for conservation areas as an incentive for the protection of indigenous biodiversity, in addition to the generation of carbon in community preservation areas.
