Estimation of erosion reduction carried out by agrosilvopasture system and its economic contribution

Soil erosion causes extensive damage to society and environment through the loss of agricultural soils and the consequent degradation of water resources. Based on this context, the The Brazilian National Water Agency - ANA developed the "Water Provider Program". Erosion reduction was estimated for the agrosilvopasture activity in the agroforestry unit of "Companhia Mineira de Metais", in Paracatu, using the methodology of the "Programa do Produtor de Água". An analysis of the economic contribution of the revenue generated through the monetary compensation provided by the "Water Provider Program" was also performed. The results pointed to a 78.52% of erosion and sediment abatement. This environmental service would therefore provide the company for an additional income of R$ 100,00.ha-1.year-1. The economic viability analysis pointed to an increase of 27.7% for NPV and EAV and of 7.0% for IRR of agrosilvopasture system, assuming the implementation of "Water Provider Program".
