“…Primarily soil contains sand and some areas of clay (Ivory et al 2019;Pott et al 2011). Related to chemical composition, Si, Al, Fe, K, Mg, Ca, and S are found in greater proportion throughout different Pantanal regions (Coringa et al 2014;Sousa and Souza 2012) and high content of organic matter (Ivory et al 2019;Pott et al 2011). The main primary types of soil are Plinthosols, Planosols, and Gleysols (Galvanin et al 2019).…”

Wildfires have increased in the last years and, when caused by intentional illegal burnings, are frequently run out of control. Wildfire has been pointed out as an important source of polycyclic aromatic hydrocarbons (PAHs) and trace elements (TEs) — such as, As, Ni, and Pb — to environmental compartments, and thus may pose a risk to human health and to the ecosystem. In 2020, the Brazilian biome, Pantanal, faced the largest losses by wildfires in the last 22 years. Ashes from the topsoil layer in Pantanal were collected after these wildfires at 20 sites divided into the sediment, forest, PF, PS, and degraded sites. Toxicity and associated risks for human health were also evaluated. The areas highly impacted by wildfires and by artisanal gold mining activities showed higher concentrations for TEs and PAHs than the protected areas. Pb varied from 8 ± 4 to 224 ± 81 mg kg −1 , and total PAH concentration ranged between 880 ± 314 and 1350 ± 70 ng g −1 , at sites impacted by anthropogenic activities. Moreover, health risk assessments for TE and PAH indicated a potentially great risk for children and adults, via ingestion, inhalation, and dermal pathway. The carcinogenic risks exceeded reference values, for both TE and PAH, suggesting harmful conditions, especially for vulnerable groups, such as children and the elderly.

“…Conforme De Sousa et al (2015) tal aspecto pode estar relacionado à deficiência do rio no processo de transporte de sedimentos grosseiros (areia). Neste sentido, Sousa (2003) enfatiza que por ser uma área localizada no alto curso e de planície, com característica de baixa declividade e baixa velocidade do fluxo de água, há tendência à deposição inicial de material mais grosseiro e, que, por suspensão o material mais fino seja depositado mais à foz do rio.…”

The fluvial dynamics corresponds to the natural changes of river channels that can influence the water energy, type and morphology of the gutter, geological structure and soil types. In this context, the type of soil present on the banks of the rivers stands out, which due to their morphological, physical and chemical characteristics, will offer greater or less resistance to marginal erosive processes. Whit this study, we aim to verify the contribution of soil morphological, physical and chemical attributes in the natural dynamics of the right bank of the Paraguay River. The studied area is located in the Pantanal Matogrossense, sub-region of Cáceres, and comprises the right bank of the Paraguay River, in the region of Baia da Campina, approximately 10 km away from the municipality of Cáceres, Mato Grosso, Brazil. We carry out morphological, granulometric and chemical description of the soil. The data were tabulated in a spreadsheet, being subsequently analyzed and discussed. The vegetation occurring in the study area is of the seasonal / cerrado and alluvial forests type, with the presence of low and semi-shrub vegetation. We classified the soil profile in the section studied as Fluvic Tb Endoeutrophic Neosol, presenting medium texture and, in general, high levels of sand and low levels of clay. The values referring to the effective cation exchange capacity (CTC) obtained in this study, were classified from low to very good, a characteristic that allows the existence of low and semi-shrubby vegetation, which contributes to the resistance to erosive processes, even that the soil has a low presenting resistance physical structure.

“…A Geografia Ambiental, com ou sem hífem é relativamente recente no país, e sua orientação metodológica e teórica é praticada por poucos autores, conforme assinala Souza (2019a). Para inserir no debate a representação dos camponeses, seu lugar de morada no contexto do debate da Geografia Ambiental, recorremos ao Geógrafo Orlando Valverde.…”

Objetivou-se com o presente trabalho discutir o uso do termo “resistência” nos trabalhos associados à questão agrária no Brasil e na América Latina que tratam da ação camponesa, incluindo reflexões sobre comunidades tradicionais, sobretudo no Cerrado. Pretende-se, então, compreender o modo pelo qual os sujeitos estabelecem relações sociais e ambientais de seu cotidiano. A orientação metodológica parte da análise de artigos, dissertações e teses publicados na área de Geografia Agrária e Ciências Humanas. A abordagem teórica pauta-se nos princípios da Geografia Ambiental e da Ecologia Política. Os resultados apontam que é possível conceber outra dimensão conceitual na relação estabelecida entre os camponeses enquanto classe social e a participação deles no contexto ambiental, pois praticam o que será defendido como Resistência Socioambiental.
