Agroforestry systems play a key role in the food security of rural and urban populations, as well as an alternative model for environmental recovery through their floristic diversity and ecological functions. The objective was to analyze the geospatial distribution of agroforestry systems in the State of Pará as a strategy for environmental recovery and food security. The study was conducted in the State of Pará, based on information provided by the agricultural census of the SIDRA (IBGE Automatic Recovery System) collection, and adopted information on land use in agricultural establishments with the census conducted in 2017. The software QGIS was used as a tool to elaborate the quantitative thematic maps of the geospatialization of the number of establishments and planted area of SAFs in the state of Pará. The Jenks method (natural breaks) was used through four interval classes to identify similar values, maximizing the difference between the classes. The results point to the increasing use of Agroforestry Systems in the Northeast Paraense mesoregion, highlighting the municipality of Acará, located in the Tomé-Açu microregion as the area with the largest number of establishments with SAFs, as well as the efficiency of the application of the method. Jenks as a tool in geospatialization of areas occupied with existing agroforestry systems in the State of Pará.
