The biodiverse agroforestry systems (ASFs) are agroecologic productions that gather both rural and forestry cultivations. This research aimed to assess - through different alometric equations - the economic valuation of ecosystemic services on carbon sequestration in SAFs, based on the carbon stock estimation of the aerial parts of the plants sowed throughout the bio diverse SAFs from the Lagoa Grande Settlement in the district of Itahum, Mato Grosso do Sul State. The study was performed from August, 2016 to September, 2017; the methodology was based on one-meter height shrub and tree species collection, with chest height circumference (CAP). The average values were measured based on chest height diameter (DAP) plus the height itself; data showed the total value of fresh and dry biomasses and the carbon stock. The results of the total amount of individuals, ranged from 291 to 365. The highest average values found for the carbon amount in tons by 0.5 ha-1, found on the aerial parts of the shrub and tree species belonged to the SAF 4, with 6.87 tons; in second place SAF 1, with 5.15 tons and finally SAF 2, with 4.03 tons. Based on this reality, the owners of the properties could be paid US$852,87, US$639,77and US$505,24, respectively. Data showed the viability of the agroforestry systems in the increment of the familiar income, besides stimulating the continuity of the agroforestry cultivation, thus showing the economic viability of the assessed systems.
