Dinâmica do uso e cobertura da terra e avaliação dos serviços ecossistêmicos com o software InVest: estudo de caso em São Geraldo do Araguaia (PA). 2023. Trabalho de Conclusão de Curso (Bacharelado em Engenharia Florestal) – Universidade do Estado do Pará, Belém, 2023.https://bibliotecadigitaldetcc.uepa.br/handle/riuepa/503In this study, we investigated the impact of anthropogenic intervention on the environmental systems of São Geraldo do Araguaia (PA), with a focus on the transformation of native vegetation into pastures due to the expansion of livestock and agricultural activities. The research addressed the loss of biodiversity and ecosystem services over a 30-year period, highlighting the significant conversion of 148,250.14 hectares of forested areas into pastures, while 7,100.53 hectares of non-forest natural formations were also converted. The results indicate substantial losses, with 157,620 hectares of pasture experiencing moderate degradation and 28,916 hectares severely degraded, impacting cattle productivity. The study also projected a loss of 6,880 MgC (megagrams of carbon) from vegetation by 2051 as a consequence of agricultural and livestock development. This carbon loss will have implications for urban areas, signaling potential climate changes. Furthermore, the economic value of carbon sequestration services was estimated at $53,899,867.42 by 2021, while the estimated carbon loss over the 30-year period (1991-2021) amounted to 25,156,055.01 MgC, representing a value of $41,507,490.76. Carbon degradation revealed significant impacts on the area, indicating the need for sustainable management practices to conserve biodiversity and ecosystem services.Língua PortuguesaAbertoAmazonInVestEcosystem servicesValuationTrabalho de Conclusão de Curso (TCC)
