Open AccessThis research aimed at analysing the economic feasibility of stablishing agroforestry system with eucalypt in savanna areas. The wood produced should be allocated to sawmills and energy production. The effect of changes in the discount rate, land value, prices of wood, soybean and rice, the proportion of wood destined to sawmill and energy and production cost. The research was conduct in Paracatu county in Minas Gerais state. The economic criteria used was the Net Presente Worth (NPW). The results showed that the agroforestry system is feasible only if 5% or more of the wood produced is allocated to sawmills and the remaining wood is used for energy or for other purposes that reaches the same value or higher in the market. Discount rates higher than 11,45% per annum; land prices over US$ 200.90/ha; productivity lower than 20.86 st/ha.a; meat price lower than 16.75/15kg ; lumber for sawmill lower than US 5.24/st; rice and soybean price below US$ 6.34/60kg and US$5.96/60kg respectively; total production cost increase of more than 5.37% render the project economically unfeasible.
