Abstract
Agroforestry systems (AFS) in coffee plantations absorb carbon dioxide, thus contributing to climate change mitigation. Furthermore, payments for environmental services related to carbon sequestration and storage represent an alternative way to generate added value for production, which will benefit coffee producers. The purpose of this study was to quantify the carbon sequestered and stored in agroforestry systems for coffee plantations. To analyze the extent to which AFS impacts environmental services in coffee cultivation, the Guide for Carbon Determination in Small Rural Properties, a methodology of the World Agroforestry Centre (ICRAF), was used. The study was conducted in the Bolognesi and Divisoria areas, located in Aucayacu, Huánuco region, where 10 soil samples and 10 samples of leaves and fruit were collected from each area to obtain carbon data. These samples were analyzed in the laboratories of the National Agrarian University of the Jungle and at Servicios Analíticos Generales S.A.C., where carbon sequestration in soil, leaves, and fruit was estimated. The economic value of each sample was also determined. The highest carbon sequestration for the Bolognesi area was 33.4g, and for the Divisoria area, it was 34.6g, resulting in a maximum economic value of 9 and 8.8 soles, respectively. The results indicate that the agroforestry system (SAF) does not significantly impact "environmental services" with regard to carbon sequestration capacity in coffee cultivation, as other factors such as shade percentage, nutrients, fertilizer, etc., are involved.
