Regarding the historical process of land use and cover in Brazil, there is the degradation of native vegetation in the called permanent protection areas (APPs), on the banks of rivers. In Southeastern Pará, with the expansion of livestock activity over time, these areas were impacted, generating biodiversity loss and pressure on water bodies. This paper the land use and cover dynamics was analyzed in two areas in the municipality of São Domingos do Araguaia -PA to simulate the priority areas for arboreal component inclusion, aiming for the restoration of APPs in a farm and a rural settlement, if strategies of arboreal component inclusion are adopted. In both case studies, there are degraded pastures in extensive areas, driven by the expansion and intensification of traditional livestock in the region from 2004 to 2014.

The research aimed to generate models of livestock agroforestry systems that can contribute to the redesign of the rural landscape and local development in southeastern Pará. The research was carried out from 2018 to 2020 in the municipality of São Domingos do Araguaia - PA. Tree species with the potential to integrate livestock agroforestry systems in different types of arrangements were selected according to local specificities based on bibliographic research and a field experiment that analyzed the management, production of nutritional quality of the species tested, namely: Gliricidia sepium (Jacq.) Walp., Guazuma ulmilifolia Lam., Albizia saman (Jacq.) F. Muell., Erythina glauca Willd. and Chloroleucon tortum (Mart.) Pittier ex Barneby & JW Grimes. From the results, the models of eligible arrangements were simulated, according to the biophysical characteristics of the location. The research also simulated the redesign of the rural landscape on a farm and a settlement in the municipality of São Domingos of Araguaia in the case of adopting strategies for incorporating the tree component in the rural landscape to restore the permanent protection area. Based on the results of the research, agroecological records on species and arrangements were prepared to support the work of rural technical assistance in the municipality to adopt these systems.
