Economic viability of an agroforestry system for indigenous communities in Brazil: a differentiated approach to risk reduction
In this paper the financial properties, economic viability and the risk of investing in an agroforestry system (AFS) for indigenous communities (IC) are evaluated to address a critical gap in the literature. An AFS proposal was designed by: (1) assessing raw data from a rural extension project, university and IC Guarani Kaiowá in the Indigenous Reserve of Dourados (IRD); (2) collecting notes and data from local field experts and IC; (3) selecting a scheme from the literature. The AFS was prepared to meet the needs of the IC, mainly food security, income generation, medicine, timber, cultural aspects, welfare. The AFS included a wide range of species, aiming at the diversified and continuous food production. The study was conducted in the IRD, Dourados, Mato Grosso do Sul, Brazil. As methods for investment analysis, capital budgeting techniques were applied. The minimum attractiveness rate (MAR) was calculated according to the hybrid CAPM model (HA-CAPM). For risk assessment, the Monte Carlo method was triggered (10,000 interactions with the variables price, productivity, and cost variables) using the triangular probability distribution. The AFS showed economic viability, with NPV and EUAV values greater than zero, IRR and MIRR greater than MAR (12.80%), PI greater than 1 and the payback period less than the project duration. The analysis confirmed the economic viability (probability of a negative NPV was null). The research findings provide a comprehensive insight into the importance of AFS in promoting economic well-being and support the implementation or strengthening of AFS in IC, bearing in mind that problems and solutions should not be narrowed to a capitalist approach.
期刊介绍:
Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
