In times of socio-environmental crisis, every agroecosystem on the planet plays a fundamental role in planetary stability. This is the case of dynamic agroforestry systems (DAS). These agroecosystems are born as a productive alternative to conventional agriculture. Although the institutions which are part of Shared Space in Agroforestry Systems network (ECO-SAF) have been installing and promoting DAS since 2008, it didn't have a study on their capacity to provide agroecosystem services to society and the planet. Thus, the present work estimated the agroecosystem services provided by the DAS of the ECO-SAF network in three case studies in the inter-Andean valleys of Cochabamba. The methodology used was the Agroecosystem Services Capacity Index (ICSA), which considers 23 agroecosystem services. It was determined that the DAS have a relevant to medium-high capacity to provide agroecosystem services since the agroecosystems with land cover that have DAS provided a greater diversity of services (between 18 to 22 services). The rating for the 23 agroecosystem services within the three case studies showed that the services with high ratings were nutrient regulation, occupational safety, pesticide-free food products and water purification (quality). Each case study also had its ICSA, resulting in a high average capacity for orchard N°1 and N°2 with an index of 2,3 and 2,9, respectively. While orchard N°3 had a relevant capacity with an index of 1,7. Additionally, a threshold (from 0 to 3) for the ICSA was generated. Finally, the potential of the ICSA methodology as a planning tool is evident, because it shows which agroecosystems provide the greatest agroecosystem services.
