Sistemas agroflorestais pecuários: o uso de espécies arbóreas como alternativa para o redesenho da paisagem rural e reabilitação de pastagens degradadas em São Domingos do Araguaia - PA

Abstract

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.
