Avaliação Da Erosão Dos Solos Na Bacia Hidrográfica Do Rio Pequeno, Paraty-Rj

Abstract: A erosão dos solos é um fenômeno natural que vem se acelerando pelas atividades humanas desenvolvidas de forma inadequada, resultando na degradação dos solos e de suas múltiplas funções. Nesse sentido, o objetivo do trabalho é avaliar o estado ambiental da bacia hidrográfica do rio Pequeno – Paraty/RJ, com destaque para a problemática da erosão dos solos. Os procedimentos metodológicos envolveram levantamentos bibliográficos e documentais, trabalhos de campo, análises de atributos do solo e mapeamentos temátic… Show more

“…After the urban areas, agriculture is the second land use that affects the quality of the water the most (Mello et al, 2020). The spatial transformations across the hydrographic basin can contribute to the vulnerability to floods, and, consequently, to the loss of crops and depredation of the property (Caldas et al, 2018), letting the terrain unprotected and subjected to a greater superficial outflow with the probability of an increase in soil loss (Santos & Guerra, 2021) a characteristic identified in the study by Moura-Bueno et al (2018), where the quantification of soil and water losses in parcels with natural vegetation was significantly lower while compared to parcels of crops with uncovered soil. The change of the native vegetation to pasture is also an aggressive practice to the environment and occurs due to the need of feeding animals through grazing, being an economic alternative for producers who prefer pasture to the cultivation of lands (Buonocore et al, 2021).…”
