CONGABA VIABILIDADE ECONÔMICA DE SISTEMAS AGROFLORESTAIS EM NOVO PROGRESSO, PARÁ.

Abstract: SAFS are the set of techniques of management and use of the soil that imply in the combination of trees with perennial crops, with livestock or with both, of joint form or staggered in the time and the space. The objective of this work was to estimate income generation, through an economic viability analysis, through the introduction of agroforestry systems (SAFs), enabling farmers to make decisions on their investment before it is even implemented to minimize frustration and loss of capital, on family farmers' properties in the Sustainable Land Development Project Our Land located in the municipalities of Novo Progresso and Altamira. Altogether 44 family units, randomly distributed in the settlement, showed interest in participating in the implementation of SAF promoted by Projeto Horizonte Verde. We selected 18 producers to whom questionnaires were applied in the form of personal interviews. In order to compose the value of the revenues, data were obtained on the market prices of products marketed at Novo Progresso's municipal headquarters, by means of a questionnaire, for the purpose of verifying the values ​​of products such as seeds, fruits, wood, cereals and others products. It was verified that, with the exception of the S4 arrangement, a large part of the arrangements of SAFs analyzed was shown to have a positive income estimate, since the values for Net Present Value (NPV), internal rate of return and cost benefit relation were positive in a horizon of 20 years. The six most profitable arrangements, classified by the NPV criterion, were the S18, S2, S10, S11, S1 and S12 arrangements, which were characterized by having high annual productivity and acceptance in the local market. Most SAFs were designed through an interactive analysis of NPV, TIR and RB / C indicators, making it possible to make investment decisions. The most economically profitable SAFs presented in their composition acai (Euterpe oleracea Mart.) and cumaru (Dipteryx odorata Willd). The amounts spent on cultural dealings and harvesting are the ones that most demand labor, and are responsible for a large part of the total costs of the SAFs in the 20-year estimate.  Keywords: agroforestry yield, family farming, economic analysis.
