O papel de fatores naturais e antrópicos na variabilidade da perda de solos no estado de Goiás entre 1985 e 2018

Abstract: A perda de solos depende de fatores naturais e antrópicos com elevada variabilidade espacial e temporal que podem ser inferidos por modelos de predição como a Equação Universal de Perda de Solos Revisada (EUPS-M). Nesse sentido, o objetivo deste trabalho é analisar a distribuição e a variação espaço-temporais das perdas de solo no estado de Goiás para os anos de 1985, 2000 e 2018, a partir da aplicação da EUPS-M, tendo a bacia hidrográfica como unidade de análise multiescalar. Os resultados demonstram que, em … Show more

“…This is probably due to the predominantly flat to gently undulating relief with a dominance of Ferralsols, which prevented any accelerated erosion by water runoff after savanna fires in 1975. In 1975and 1985, anthropogenic activities such as the excavation of surface material for the opening of new roads significantly affected soil losses through water erosion. This is particularly the case for the Acampamento Basin, on the edges of BR-020 road, for the Barrigudo Catchment, along DF-001 road, and along the northern margin of the Torto Watershed (Figure S3.2 in Siame et al, 2023).…”

“…In Brazil, there is also a large corpus of studies using the universal soil loss equation (see e.g., Gomes et al., 2019; and references in Rosa et al. (2023)) and experimental runoff plots (e.g., Fonseca et al., 2021). According to Borrelli et al.…”

“…Alluvial deposits, composed of sand and gravel, occur in transitioning from these to the lower and flatter parts [27]. In the higher and residual areas, there is a predominance of Plintossols (Petric) with a texture varying from clayey to gravelly, followed, sometimes, by steep segments with the occurrence of Leptsol (Litholic) with sandy to gravelly texture [28,29]. At intermediate altitudes are flatter areas with a predominance of Ferralsol (Red) with a clayey to very clayey texture and, to a lesser extent, Ferralsol (Red-Yellow) with a clayey texture.…”
