The Brazilian Cerrado, a biodiversity hotspot, faces severe threats from agricultural/livestock expansion and land degradation. This study investigates the potential for implementing autochthonous silvopastoral systems (SPS) as a sustainable land management strategy to conserve biodiversity and enhance ecosystem services in the landscape. Despite documented benefits, the adoption of these systems remains low. The first chapter aimed to conduct a bibliometric analysis to understand the global research state of the art on SPS adoption using the PRISMA methodology. A total of 58 documents were analyzed, with an average of 18.45 citations per document and 3.07 citations per document per year. The study identified the main countries in terms of publications on SPS adoption as the United States of America, Germany, Colombia, Brazil and Mexico. International collaborations were observed through co-authorships, which represented 48.28% of the listed works. The analysis highlighted the most relevant journals, with Agroforestry Systems being the leading journal. The results show a significant increase in research on SPS adoption in recent years, focusing on understanding the barriers and motivations for adoption. Additionally, in the second chapter, the study assesses the potential for conservationist use (PCU) in the Pardo River and São João do Paraíso hydrological watersheds, in the North mesoregion of the Minas Gerais state, estimates and map ecosystem services and identify priority zones for autochthonous SPS. Santo Antônio do Retiro, Montezuma, and Rio Pardo de Minas exhibit the highest PCU scores among the municipalities. The study highlighted good soil and slope conditions in the region but also faced challenges with low annual water yield. Thus, it is emphasized that the adoption of autochthonous SPS can bring benefits in high-suitability areas. In conclusion, the adoption of autochthonous SPS in high-suitability land cover types such as savanna formation, perennial crops, and forest plantations offers a viable strategy to enhance ecosystem services, support biodiversity conservation, and promote sustainable land use. This research also highlights the role of public policies, such as payment for environmental services, in promoting and facilitating the adoption of autochthonous SPS.
