The Tilacancha Private Conservation Area provides fresh water to the city of Chachapoyas. 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); they were integrated into USLE, obtaining A = R ∗ K ∗ LS ∗ PC, (t/ha.yr). Six ranges of erosion were found, and 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%, and the erosion ranges would vary from 0.2 to 1028.84 t/ha.yr.
