Resumen

This study aims to evaluate the dynamics of vegetation cover using NDVI in the Condebamba Valley, Cajamarca, between 2003 and 2024. The results record variations in vegetation cover; the maximum NDVI has increased, reflecting improvements in certain areas due to conservation strategies and vegetation regeneration. However, the minimum NDVI has decreased significantly, indicating greater soil degradation due to deforestation, urbanization, illegal mining, and the reduction of water resources as a result of climate change. The average NDVI increased from 0.245 in 2003 to 0.257 in 2024, evidencing vegetation loss. In 2024, the maximum NDVI reached 0.615, and the minimum was recorded in 2014 (- 0.131), then decreasing to -0.102 in 2024, reflecting a fragmentation of the natural landscape with slow recovery of vegetation cover. Although some areas show signs of restoration, others continue to deteriorate. Urban expansion, land-use changes, illegal mining in the area, and climate change have all influenced this process. Strengthening conservation and reforestation strategies is recommended to mitigate these effects.
