SUMMARY:

The Amazon faces deforestation challenges driven by the expansion of pasturelands, which generates significant environmental impacts and reinforces the need for production models that reconcile environmental restoration and income generation. In this context, agroforestry systems (AFSs) emerge as an alternative by integrating tree and agricultural species within the same production system. Considering the need to expand information on the economic and financial feasibility of these systems, this study analyzes four agroforestry consortia based on açaí palm, established in Porto Velho, Rondônia, Brazil. For the analysis, 1-hectare systems were considered for each arrangement: AFS 1 – açaí, coffee, Brazil nut and cassava; AFS 2 – açaí, banana, cocoa and cassava; AFS 3 – açaí, andiroba and cassava; and AFS 4 – açaí, cupuaçu, banana and cassava. An ex-ante financial analysis was conducted, based on expected results, using actual establishment costs and estimates of post-establishment costs, productivity and prices obtained from the literature, consultation with technical experts and projects with practical experience. The analysis considered a 20-year horizon (2025–2045), with data tabulated in Microsoft Excel spreadsheets. The following indicators were calculated in Excel: Net Present Value (NPV), Internal Rate of Return (IRR), Equivalent Annual Value (EAV), benefit-cost ratio (B/C), payback period and Remuneration of Family Labor (RFL), adopting a discount rate of 6% per year. The results showed that all systems are economically feasible, presenting positive NPV, IRR above the discount rate and benefit-cost ratio greater than one, indicating value generation over time. AFS 1 stood out for its best economic performance, with higher profitability and shorter payback period, while AFSs 2 and 4 showed greater revenue stability due to productive diversification. AFS 3, although feasible, showed lower economic attractiveness. Açaí was consolidated as the main revenue component, exerting strong influence on the financial performance and sensitivity of the systems to price variations. The sensitivity analysis, considering price variations of +10%, +20%, -10% and -20% for the crops, showed that all systems remain feasible even under adverse scenarios, including a 20% reduction in crop prices. Under the models and conditions studied, input costs were found to be concentrated in the establishment phase, while labor demand intensified in the intermediate years, following the increase in management and harvesting activities. RFL proved to be competitive, reaching values three times higher than the regional opportunity cost. Despite their feasibility, the systems showed relatively long payback periods due to low revenue generation in the initial years. Expanding cassava production cycles could help improve cash flow and reduce the payback period; however, this strategy requires adjustments to the spatial arrangement of species, particularly spacing, to avoid excessive competition. It is concluded that the evaluated agroforestry consortia are economically feasible and resilient alternatives for the Amazon. However, the choice of system should consider not only financial indicators, but also factors such as management capacity, labor availability and market access, in order to ensure long-term sustainability.
