“…Also, it gives way for a residual effect associated with the disturbance of the soil and sediment deposit in susceptible areas, which are easily carried away in subsequent events. According to Garfur et al (2003) According to the previous analysis, it was identified the effect of the characteristics of the event on the sediment yield in the next events. This way, the characteristics of the event of february 18 influenced in the sediment yield of the subsequent event (March/04).…”

“…Despite there having been some studies conducted in semiarid regions on the changes in the pattern of sedimentological responses, the research needed to have been implemented in such a way as to generate information at the ephemeral small watershed scale, primarily investigating the influence of man on the alteration of natural processes (erosion, superficial runoff, maximum outflows, infiltration, etc.) (BARTLEY et al, 2006;GARFUR et al, 2003;GARCIA-RUIZ et al, 2008;SANTOS et al, 2011).…”

“…Abundant studies have uncovered that persistent severe erosion can deteriorate soil conditions, reduce water holding capacity, decrease aggregate stability and soil biodiversity, and bring serious ecological crisis such as eutrophication, non-point pollution and eventually land degradation (Bosch and Hewlett, 1982;Gafur et al, 2003;Singer and Shainberg, 2004;Ulén and Kalisky, 2005;Jin et al, 2008). For example, a study in America indicated that the crop yields would be reduced by 2 to 4% if current water erosion rates continue for the next 10 decades (Trimble and Crosson, 2000).…”

“…Deforestation, cultivation of steep slopes and other strong agricultural activities have induced severe erosion and land degradation in huge areas around the world (Bosch and Hewlett, 1982;Gafur et al, 2003;Chen et al, 2007a). Proper land use adjustment and vegetation restoration, however, can improve the effectiveness of land cover, consolidate the heath and stability of local ecosystems, and reduce the sensitivity of soil erosion and water loss to temporal changes in rainfall (Dunjó et al, 2004;Merz et al, 2006;Eugenia et al, 2007).…”

“…Segundo vários autores (Ewel et al, 1981;Uhl & Jordan, 1984;Lugo & Sanchez, 1986;Hölscher et al, 1997;García-Oliva et al, 1999;Gafur et al, 2003;Sá et al, 2006-7;Davidson et al, 2007), o corte e a queima da vegetação seguidos do cultivo acabam por desestabilizar a dinâmica da ciclagem de nutrientes, resultando na conseqüente perda de nutrientes do sistema solo-vegetação, e podem resultar também em processos erosivos e de degradação do solo (Singh et al, 1992;Soto et al, 1995;McDonald et al, 2000), dependendo do tamanho da área aberta. Para Sanchez & Leakey (1997), por exemplo, a redução da fertilidade do solo causada em grande parte pelas atividades agrícolas de corte e queima é uma das principais causas de insegurança alimentar na África.…”
