Agroforestry systems as new strategy for bioenergy — Case example of Czech Republic

Abstract

The paper deals with the analysis of economic efficiency of innovative agroforestry systems (AFS) using coppiced tree belts (CTB), which combine the advantages of traditional alley cropping with the short rotation coppice (dense plantation of fast-growing trees for biomass — SRC) on an agricultural field. We have analyzed and compared such innovative agroforestry system (AFS-CTB) with conventional food crops production in conventional 4 crop year rotation (winter barley, winter wheat, rapeseed and corn). The minimum price of production, (based on net present value criterion), was performed to enable simultaneous assessment of annual and perennial crops over time in order to obtain also economic evaluation and comparison. Our results show that AFS-CTB generate similar income and profits as from conventional annual crops when cultivating on suitable sites and adhering to good farming principles.
