“…The impact of rainfall is one of the main factors in aggregate breakdown as well as the shear stress of water flow. This process generates soil erosion from the transport of sediment [10,11,21]. Erodibility is related to the susceptibility of soils to erosion by rainwater and runoff, is a parameter of great importance for predicting soil loss, and is associated with soil physical and chemical properties [21][22][23].…”

“…This process generates soil erosion from the transport of sediment [10,11,21]. Erodibility is related to the susceptibility of soils to erosion by rainwater and runoff, is a parameter of great importance for predicting soil loss, and is associated with soil physical and chemical properties [21][22][23]. The topographic factor is an essential parameter in determining the influence of slope (factor S) and slope length (L) in order to quantify the erosion generated by the influence of the water velocity from surface runoff [24,25].…”

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.

“…Pins are widely used to measure the retreat of gully edges and riverbanks. On slopes, pins have enabled measurements of sheet erosion and estimates of soil losses (HART et al, 2017;JUGIE et al, 2018;KEARNEY et al, 2018;MYERS et al, 2019;GUERRA et al, 2020;GHOLAMI et al, 2021). collection, low maintenance requirements which reduces operational costs, the possibility of data collection at flexible intervals, whether weekly, monthly, or annually, ease of detection in areas where erosion is occurring, and particularly the low technical level required for data collection Despite the advantages of this methodology, there is a scarcity of studies that demonstrate the systematization of data from erosion pin readings, as well as the calculations of soil losses under the application of hydrogels from the field readings.…”

Erosion pins are considered a simple and inexpensive way to estimate soil losses due to erosion and have been used in different environments with different degrees and types of erosion. Despite the advantages of this technique, there is a shortage of studies that demonstrate how data systematization and soil loss calculations are performed using this technique. Therefore, this study aimed to present the step-by-step data systematization process of erosion pins obtained in the field and the calculation of soil losses, with the measurement of soil losses under the effect of hydrogel. Readings from 16 pins installed in an area cultivated with soursop trees planted on contour lines and associated with stone rows were monitored weekly between 19/02 and 19/03/2022 by measuring the distance between the soil surface and the end of each pin. The readings were organized by pin and date of measurement. Subsequently, soil lowering and burial, soil density, useful area of each pin, and soil loss in kg/m3 and Mg/ha-1 were determined, enabling statistical analysis and technical interpretation of the data.

Ethnoknowledge has become an approach used in schools to better understand the conceptual bases for understanding content. This is in line with the Nós Propomos Project, which has a territorial citizenship dimension. Together, they constitute the applicability of knowledge in a Basic Education school in the city of Sobral, Ceará, together with researchers from Academia. On this occasion, the study of the environment from the perspective of the Brazilian semiarid region was addressed, especially the local one. It was possible to address topics from the daily lives of the students, these high school students, who brought up the local problems experienced by the community and the possible answers to the problems. Workshops and field visits were held, accompanied by debates among the participants. The result was the expression by the students regarding their position on the issues involving the semiarid environment and its potentialities and weaknesses.the semi-arid environment and its potentialities and weaknesses.
