Abstract

The growth of the mining industry is an essential part of the development of the world economy and in Peru. However, it has negative consequences for biodiversity, modifying soil quality and loss of highly valuable plant cover if sustainable management is not carried out. Therefore, the objective was set to determine the temporal analysis of the Yanacocha mining expansion on the vegetation cover during the period 1990 - 2023 of the Cajamarca province, Peru. For this, satellite images from LANDSAT 5, LANDSAT 7 and LANDSAT 8 were used. Likewise, Google Earth Pro, shapefiles and after that, the NDVI vegetation index (Normalized Difference Vegetation Index) was used for the vegetation cover analysis. and the combination of bands for analysis of mining surfaces, these were processed in ArcGIS 10.8 software. The results show us the loss of vegetation cover is 6,740.30 (Ha) in the 33 years of study. Likewise, mining expansion grows at an accelerated pace, increasing by 6737.61 (Ha) in the period of analysis. It is concluded that most of the loss of vegetation cover was due to the growth of mining.
