Agroforestry systens (AFS) have been suggested as productive solution to these areas, it involves simultaneous or consecutive planting of forest plants with agricultural crops and / or animals in the same area. It is an activity that has risks and uncertainties regarding its economy, with the need for economic evaluations. This study aimed to analyze the economy of four AFSs and their contribution to family productive units income in the Settlement Belo Horizonte I, in São Domingos do Araguaia-Pará. The data relating to expenses and income for each AFS were collected through structured interviews with family members and in the local market. Information from technical indices of each culture were searched in literature. To analyze economic feasibility were used as indicators as net present value (NPV), internal rate of return, benefit / cost ratio and equivalent annual value were used. All AFSs analyzed were considered economically viable in a 21 years planning, with a discount rate of 1% per year. This is indicated by the rate of Funding of the National Forest Programme for Strengthening Family Agriculture online. The AFS B acai, cacao, yellow ipe, ipe white, orange, cassava, maize, mahogany, teak and paricá was the best financial performance in relation to the AFS A banana, guava, soursop, yellow ipe, white ipe, ipe purple, cassava and teak paricá, AFS C cashew, guava, white ipe, maize, mahogany, teak and paricá, and AFS D avocado, acai, banana, yellow ipe, ipe and purple neem, presenting a greater diversity and higher revenues from the first year of the project. The hand labor accounted for the largest share of total costs of the AFS, the AFS C having more participation, representing 78.3%, followed by the SAF D with 73.22%, AFS B 68.56% and AFS A 61 78%. The AFS B was the largest contributor to the average gross income of the family during the 21 years of the project, accounting for 12.36%, followed by AFS A, C and D, which contributed on average 6.53%, 3, 33% and 6.06%, respectively.
