Predicción espacial de la erosión del suelo en zonas áridas mediante teledetección. Estudio de caso: Quebrada del Diablo, Tacna, Perú

Abstract: La presente investigación trata sobre la evaluación de la erosión hídrica del suelo en una zona árida de la región Tacna al sur de Perú, tomando como caso de estudio la Quebrada del Diablo. Se usaron los modelos USLE (Universal Soil Loss Equation) y RUSLE (Revised Universal Soil Loss Equation) en conexión con sistemas geográficos de información (GIS) y técnicas de teledetección. Los factores R, K, LS, C y P de los modelos fueron calculados a partir de información pluviométrica local registrada en tres estacion… Show more

“…In addition, Rosas and Gutierrez [103] agree with the quantification of erosion variability, finding an increase in erosion in the direction of R4 to R3, the latter region being the region with the highest erosion in the western Andes of Peru. In R2, the results are in the range obtained by Mejía-Marcacuzco et al [62], with an analysis period within the years of this study of 1997-2020. In the South American region, one of the global RE products is GloREDa, which estimates this variable using globally observed data and the ERA5 precipitation reanalysis product; however, the largest differences between RE and GloREDa estimates were observed in South America due to underestimation of precipitation in mountainous regions, such as the Andes [52].…”

“…In Peru, there are investigations that use the three methods. Based on the observed-based RE approach, local studies such as that Romero et al [61] in the north of the Andean region estimated an RE of 2950 MJ • mm • ha −1 • h −1 at a point level, while Mejía-Marcacuzco et al [62] on the south coast in Tacna estimated an RE of 1190 MJ [63]; on the other hand, through the Global Rainfall Erosivity Database (GloREDa) product developed by Panagos et al [40], an RE range was estimated between 148 MJ • mm • ha −1 • h −1 in the Pacific Coast region and 14,226 MJ • mm • ha −1 • h −1 in the lowland Amazon. Using the merged-based RE technique, INRENA-Pura [64] prepared a map of soil erosion intensity at a national scale, which was published by the National Institute of Natural Resources (INRENA), using cartographic information, represented by national charts, aerial photographs, and images captured by radar and satellite.…”

“…Las enfermedades que llegan a afectar la vitalidad de los árboles son otro factor que causa la deforestación, esto se debe a una anomalía debido a la presencia de un agente externo, las enfermedades se agrupan según el tipo de patógeno y pueden ser virus, bacterias, hongos, etc. (9).…”

“…Las causas por las que se da la deforestación y erosión del suelo son principalmente las actividades que desarrolla el ser humano, existen millones de hectáreas de bosques talados con el objetivo de obtener materia prima y los suelos pasan a ser tierras de cultivo. Por otro lado, el ser humano a extendido en gran parte los núcleos urbanos, es por eso que hoy en día existe más población en las zonas urbanas que en las rurales (9,10).…”
