Resumen

This research aims to identify degraded areas due to changes in vegetation cover and land productivity in high Andean terrestrial ecosystems in a prioritized area of the upper watershed of the Huaura River, Department of Lima, which allows its categorization as a starting point to seek the appropriate recovery of these ecosystems, For this purpose, satellite information was used to recognize degraded areas in high Andean terrestrial ecosystems, which are reliable and applicable to our national territory. To identify degraded areas, pixels with a negative trend in the time series with a confidence value of 95% and a P-value lower than 0 were considered. 05, as results were 7 the ecosystems analyzed and a degradation was generated until the moment of 8,916.7 has that corresponds to the 5.01% of the area occupied by these spaces of life; in addition the studied degradation corresponded to the 3.19% of the territory of the high basin of river Huaura.
