“…A coffee-macadania system presents a higher gross income than coffee monocrop (Perdoná et al, 2013). The profitability of agroforestry systems relates to intercropping species, crop management, inputs and market prices (Bentes-Gama et al, 2005;Rodrigues et. al., 2007).…”

Agroforestry systems can reduce the risks of investing in just one crop. However, there are uncertainties like other agricultural and forestry activities. Therefore, there is the need for economic studies under conditions of economic risk of agroforestry systems. This work reports an analysis of the main components of costs and revenues of an agroforestry system with coffee and banana, as well as an analysis of its economic performance through indicators: net present value, equivalent period benefit (or cost), family labor revenue and a sensitivity analysis of net present value. The main cost components in the system are the human labor and mineral and organic fertilizers applied in coffee, and the costs for the production of coffee outweigh the costs of banana production. The monthly income from the production of bananas balances the costs of coffee production, generating a positive cash flow in the studied period. Financial indicators showed positive values, demonstrating the economic viability of the system with coffee and banana. The agroforestry system is economically feasible, even with variations of ± 20% in production costs and selling prices of their products. Variables that showed greater sensitivity on the net present value were the selling price of coffee and bananas, and the cost of coffee production.Index terms: Musa spp.; net present value; family labor revenue; sensitivity analysis. REsUMOOs sistemas agroflorestais podem reduzir os riscos de investimento em uma só cultura, no entanto, apresentam incertezas como outras atividades agrícolas e florestais. Por isso, a necessidade de realizar estudos econômicos sob condições de risco ou de sensibilidade dos sistemas agroflorestais. Objetivou-se, neste estudo, determinar os principais componentes de custos e receitas de um sistema agroflorestal com cafeeiros e bananeiras, bem como analisar a rentabilidade econômica do sistema agroflorestal por meio dos indicadores: valor presente líquido, benefício (ou custo) período equivalente e remuneração da mão de obra familiar e a análise de sensibilidade, verificando o efeito no valor presente líquido. Observamos que os principais componentes de custos no sistema agroflorestal são a mão de obra e os adubos minerais e orgânicos aplicados nos cafeeiros, sendo que os custos para a produção do café são superiores aos da produção da banana. A receita mensal da produção das bananas equilibra os custos de produção cafeeira, gerando um fluxo de caixa positivo no período estudado. Os indicadores financeiros apresentaram valores positivos, demonstrando a viabilidade econômica do sistema agroflorestal com cafeeiros e bananeiras. O sistema agroflorestal é viável, economicamente, mesmo com variações de ± 20% nas variáveis de produção e venda de seus produtos. As variáveis que apresentaram maior sensibilidade no valor presente líquido foram o preço de venda do café e da banana, e o custo de produção cafeeira.Termos para indexação: Musa spp.; valor presente líquido; receita da mão de obra familiar; análise de sensibili...

“…Para isso, os dados de custos e receitas foram analisados usando-se o software @RISK 6.0 (Palisade Corporation, 2012), desenvolvido para realizar simulações e que trabalha de maneira integrada à planilha Excel. Segundo Bentes-Gama et al (2005), esse software permite a aplicação do método de Monte Carlo para simular valores para as variáveis aleatórias receita e custo e, em decorrência dos valores aleatórios gerados, obter valores para a variável lucro.…”

RESUMOO objetivo deste trabalho foi analisar a viabilidade econômica da produção de carvão vegetal em sistema fornos-fornalha e fornos do tipo rabo-quente e realizar a simulação de risco de investimento. A análise econômica foi realizada pela determinação de Valor Presente Líquido (VPL), Valor Anual Equivalente (VAE) e Razão Benefício-Custo (B/C). A análise de risco foi realizada pelo método de Monte Carlo. O sistema fornos-fornalha apresentou maior viabilidade econômica. Os indicadores econômicos se mostraram viáveis e a análise de risco indicou probabilidade de os projetos serem inviáveis economicamente de 0,9% e 27,3% para o sistema fornos-fornalha e fornos rabo-quente, respectivamente. Conclui-se que a inclusão da análise de risco nas análises econômicas resulta em maior segurança para inferir sobre os indicadores econômicos.Palavras-chave: fornos de alvenaria, valor presente líquido, simulação de Monte Carlo. Economic Risk Analysis of Two Systems of Charcoal Production ABSTRACTThis study aimed to analyze the economic viability of charcoal production in kilns-furnace system and "rabo-quente" kilns, as well as the investment risk simulation. The economic analysis was performed by determining the following indicators: Net Present Value (NPV), Equivalent Annual Value (EAV) and Benefit -Cost Reason (B/C). The risk analysis was performed by the Monte Carlo method. Economic indicators were viable. Kilns-furnace system evidenced to be more viable economically. Risk analysis indicated that there is probability to economical unviability of evaluated systems, 0.9% and 27.3% for kilns-furnace system and "rabo-quente" kilns, respectively. Inclusion of risk analysis in economic analysis of charcoal production projects results in greater security to infer on economic indicators.

Cerrado vegetation is Brazil's second largest biome, comprising about 388 municipalities in Minas Gerais state alone and serving as an important source of natural resources. A large share of the wood charcoal produced in Minas Gerais is sourced from Cerrado vegetation. The objective of this work is to assess the economic viability of Cerrado vegetation management for wood charcoal production, under conditions of risk. The study site is a fragment of Cerrado subjected to fi ve levels of intervention as to basal area removal. For risk analysis, the Monte Carlo method was applied, using charcoal price, interest rate and land value as input variables, and using Net Present Value as output variable over an infi nite planning horizon. It was concluded that introducing risk in the economic analysis of the various Cerrado management regimes helped provide additional information to that obtained by deterministic analysis, improving understanding and ensuring safety in decision-making about the economic viability of such regimes. For all treatments, the probability of VPL being negative increases with increasing cutting cycle lengths. For all treatments, the optimal cutting cycle is ten years. Treatments where a larger volume of wood was removed proved less prone to risks of economic inviability since they secure more revenue than treatments where less wood was removed.
