ECONOMIC MODELING OF LIVESTOCK AGROFLORESTRAN SYSTEMS WITH AN EMPHASIS IN ANIMAL PRODUCTION IN THE AMAZON BIOME

Abstract

ABSTRACT: The use of agroforestry systems (SAF) has been indicated in the rehabilitation of areas of degraded pastures, mainly with the use of arboreal species of economic value. However, studies indicate that the use of forage tree species can increase livestock productivity, resulting in better and higher milk production and shorter slaughter time. In this context, economic models of silvopastoral systems and crop-livestock-forest integration were simulated based on the technical coefficients already generated by the project "Protection and sustainable use of landscapes of Brazilian biomes - Biomes Project", in order to subsidize with information the generation of Public policies appropriate to these systems. The financial indicators used were: Net Present Value (NPV), Internal Rate of Return (IRR), Cost Benefit Ratio, Annual Equivalent Value (VAE) and Payback. The analyzed models used the tree species Gliricidia sepium and Eucalyptus. All the models were considered economically viable, within a time horizon of 14 years. KEY-WORDS: Agroforestry, economic viability, Southeast of Pará.
