The environmental impacts caused by cattle are undeniable, and, in addition to the expansion of land, comprise problems related to biodiversity loss, deforestation, and greenhouse gas (GHG) emissions, the latter making the sector a main contributor to climate change. Given the social and economic importance of cattle, it is crucial to implement strategies that can both mitigate environmental impacts and allow productivity increases. Silvopastoral systems (SPS) constitute a valuable strategy for this purpose, since they generate environmental benefits, related to the reduction of GHG emissions, increased nitrogen fixation, and nutrient cycling, as well as economic benefits, such as increased production efficiency, reduced production costs, and the generation of additional income. This study evaluates the implementation of a SPS in beef cattle fattening (treatment 1, T1) in Colombia from an economic perspective and contrasts the results with a traditional grazing system under grass monoculture (treatment 2, T2). The information was collected in trials at the campus of the Alliance of Bioversity International and CIAT in Palmira, Colombia, during 2021 and 2022. The grass varieties used in both treatments were Brachiaria brizantha cv. Toledo and the Brachiaria hybrid cv. IATTC BR02/1752. The legume Leucaena leucocephala was integrated in the SPS (T1). We applied a discounted cash flow model, that allowed for the estimation of profitability indicators, and a risk analysis. According to the results, the Net Present Value was positive for both treatments. The probability that this indicator takes negative values is, however, with 21% higher for T2 than for T1 (0%). The Internal Rate of Return is 21% for T2 and 69% for T1. The Benefit-Cost Ratio indicates that for every US $ spent on the investment, US $ 1.5 are being obtained as benefit in T2 and US $ 2.7 in T1. The results suggest that the integration of Leucaena leucocephala is an economically and financially viable endeavor for the cattle producer that surpasses the traditional system by far. In addition, it leads to higher efficiency that allows increasing the annual income of the producer. The adoption of this SPS, in addition to its economic benefits, also contributes to conservation, resource-use efficiency, and mitigating GHG emissions. This study is a valuable input for actors involved in the adoption processes of SPS in Latin America, such as producers, extension agents, financial institutions, and public policy makers, since it provides an overview of what can be obtained from investing in SPS.
