Special Issue Information

Dear Colleagues,

Soil erosion is a major environmental issue, with a worldwide impact, and with direct and indirect effects on soil productivity and, consequently, on human survival. Although a natural process, soil erosion has suffered a significant increase due to human activity on the surface of the Earth, especially in recent centuries, through its diverse activities, such as intensive agriculture, overgrazing, urban sprawl, wildfires, deforestation, and industrial and mining activities. Presently, soil erosion and degradation promoted by human action has reached extreme levels, requiring urgent measures to promote soil conservation and rehabilitation.

Thus, the present Special Issue of Geosciences intends to outline the present situation we are facing in terms of soil erosion in different parts of the world, highlighting the main challenges mankind faces on this subject. The debate on future perspectives of soil erosion monitoring, evaluation and modelling, related to recent technologies and methods, as well as strategies for soil conservation and rehabilitation, are also objectives of this Special Issue.

This Special Issue aims to cover, without being limited to, the following areas: Soil erosion

  • Soil erosion modeling
  • Gully erosion
  • Post-fire soil erosion
  • Erosion mitigation techniques
  • Soil conservation
  • Erosion in urban environment.

Soils have an important task in maintaining vegetation cover and natural resources on Earth and are indispensable to societies. However, the accelerated soil erosion has become an environmental problem related to land settlement for agricultural practices and forestry and is linked to population growth. This study aimed to evaluate soil erosion in a watershed downstream of Parnaíba river, northwest of Piauí state, in the Brazilian Cerrado using geotechnology products and tools in order to understand the soil loss and map the potential erosion and actual erosion through qualitative and quantitative results to support the management and planning of the watershed in an effective and efficient way. As a modeling tool, this research used the Revised Universal Soil Loss Equation (RUSLE). The potential erosion ranged from very low to very high. The soil loss obtained by the integration of natural physical factors with land use (anthropic action) resulted in soil loss corresponding to the category slight (0–0.01 t.ha−1.year−1) to extremely high (>100 t.ha−1.year−1). The areas with the greatest soil loss were identified in land uses linked to pasture, exposed soil, and cultivated land. It was also possible to identify erosion features in the field, indicating the need to implement soil conservation practices. Full article
