CUEVAS-REYES, Venancio et al. Financial and economic evaluation of an intensive low-irrigation silvopastoral system. Rev. mex. de cienc. forestales [online]. 2020, vol.11, n.62, pp.89-110.  Epub 19-Fev-2021. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v11i62.759.

Silvopastoral systems have proved to be important for the environmental and economic sustainability of the producers who carry them out. Therefore, the aim of this work was to evaluate the financial and economic profitability of the intensive silvopastoral system Leucaena leucocephala in association with cross-bred Bermuda grass (Cynodon dactylon) under irrigation in the production of beef calves in Southern Sinaloa, in order to contribute information to productive, economic and environmental sustainability in tropical regions. By following up on the technical and economic information regarding a 20-ha production unit in southern Sinaloa for 3 years, a financial and economic evaluation was carried out considering the payment for the carbon sequestration environmental service provided by the intensive silvopastoral system (ISS). The financial analysis methodology was used, in which the three main indicators used in the evaluation of projects were estimated: Net Current Value (NCV), Internal Rate of Return (IRR) and Cost Benefit Ratio (CBR). In a time frame of 10 years of planning, the ISS is profitable, as it exhibits a NCV of 7 605 792.14 MXN, an IRR of 27.9 % and a CBR of 1.21 in the financial evaluation, and of 1.24 in the economic evaluation. The results of the present research show that calves can be developed in an ISS in a profitable and sustainable way, which is why greater institutional support is required to spread, promote and support these silvopastoral systems in tropical regions.
