Geospatial analysis of soil erosion including precipitation scenarios in a conservation area of the Amazon Region in Peru

The Tilacancha Private Conservation Area provides fresh water to the City of Chachapoyas, Amazonas. Therefore, the amount of soil lost in the year and under precipitation scenarios was determined. Individually, the values ​​of the factors were obtained: Rain erosivity (R) in 2019 and simulating increase and decrease of 15% of rainfall, soil erodibility (K), length and degree of slope (LS), land cover (C) and conservation practices (P); and they were integrated into USLE, obtaining A = R*K*LS*PC, (t/ha.yr). Six ranges of erosion were found, the ACP had areas where from 0.4 to 665.20 t/ha.yr of soil was lost. A 15% reduction in rainfall would represent a loss of soil from 0.20 to 301.56 t/ha.yr and an increase in rainfall by 15%, the erosion ranges would vary from 0.5 to 1028.84 t/ha.yr.
