“…Farming, habitation, terracing, deforestation, and overgrazing are some of the activities which lead to increased soil erosion rates. Soil erosion process has three distinct phases: detachability, transportability, and deposition [27][28][29]. Soil erosion process begins with detachment, where breakdown of soil particles occurs due to raindrop impact, shearing, and/or the drag force possessed by wind or even through forces that result from tillage activities [24,[30][31][32].…”

“…Waterborne erosion is more pronounced when the two rainfall attributes are on the higher side [86]. Rainfall erosivity factor (R) quantifies the erosive power possessed by rainfall, and it much depends on the rainfall's intensity and amount [29,60,86]. e R factor is expressed as the sum of EI-values for each particular storm for a year and averaged for over long periods of time (more than 20 years) so as to accommodate discernible recurring rainfall patterns [29].…”

“…Vega e Flebes (2007) ressaltam que a agressividade das chuvas está relacionada com a energia cinética, que embora pouco discutido em meteorologia e climatologia, é fundamental na agricultura e silvicultura devido à sua contribuição substancial para a erosão e degradação dos solos. Tsitsagi et al (2018) afirmam que vários eventos de chuvas muito intensas são responsáveis pela maior proporção de erosão do solo.…”

“…Under the background of global climate change, the soil erosion rate varies due to various reasons, among which the most direct reason is the changes in rainfall erosivity (Tsitsagi et al 2018). The general soil loss equation (USLE) put forward by Wischmeier and Smith (1978) and the revised USLE (Renard et al 1991) are most commonly used to calculate soil erosion rate.…”
