Earth's Future, Volume 11, Issue 8, August 2023., 2023 Abstract Land degradation resulting from increased continental surface erosion is a worldwide and systemic phenomenon due to unsustainable human activities. Already fragile, the intertropical zone is likely to be further affected by climate change like increased aridity, an aggravating factor of soil erosion and land degradation.

Understanding the Environmental Impact of a Mine Dam Rupture in Brazil: Prospects for Remediation
Journal of Environmental Quality, Volume 48, Issue 2, Page 439-449, March-April 2019., 2019 The rupture of the Fundão mine dam in Mariana municipality, Minas Gerais State, Brazil, spilled the tailings across the Doce River basin. These tailings, composed of residues discarded from the beneficiation of iron ore, are rich in SiO2 and Al2O3, as well as some ether amine compounds and NaOH.
