Economic viability of agroforestry systems in Novo Progresso (PA)

Abstract

SAFs are the set of management and land use techniques that involve the combination of trees with perennial crops, with livestock or with both propositions, together or staggered in time and space. The objective of this work was to estimate income generation through an economic viability analysis, by introducing agroforestry systems (SAFs), allowing producers to make decisions on their investment even before it is implemented to minimize frustrations. and loss of capital on family farmers' properties in the Terra Nossa Sustainable Development Project, located in the municipalities of Novo Progresso and Altamira. In all, 44 family units randomly distributed in the settlement showed interest in participating in the implementation of AFS promoted by the Green Horizon Project. Eighteen producers were selected and questionnaires were applied in the form of personal interviews. To compose the value of the revenues, data were obtained on the market prices of the products sold at the Novo Progresso municipal headquarters, through the application of a questionnaire to verify the values ​​of products such as seeds, fruits, wood, cereals among other products. With the exception of the S4 arrangement, most of the analyzed SAF arrangements were found to have a positive income estimate, since the values ​​for Net Present Value (NPV), internal rate of return and cost-benefit ratio were positive in one. 20-year horizon. With regard to SAF revenues and balances, it is observed that the six most profitable arrangements, classified by the NPV criteria, were the S18, S2, S10, S11, S1 and S12 arrangements that stood out for having species with high annual productivity and acceptance in the local market. Most SAFs analyzed point to economic viability according to NPV, IRR and RB / C indicators, allowing the producer to make investment decisions. The most economically profitable SAFs presented in its composition acai (Euterpe oleracea Mart.) And cumaru (Dipteryx odorata Willd). The amounts spent on cultural treatment and harvesting are the most labor intensive, accounting for much of the total costs of SAFs in the estimate made for 20 years.
