Análisis multitemporal de la degradación de los bosques en la Amazonía ecuatoriana-zona 2

Abstract

Abstract: The present study analyzed the area occupied by forests in the 2018-2022 evaluation period, for which different remote sensing techniques and cartographic processes were implemented, based on Landsat satellite images provided by EARTH EXPLORER, being processed with QGIS 3.2 and ARCMAP 10.8 software, where corrections and enhancements were made to improve their quality, which in turn were used for unsupervised classification where different categories were assigned to each pixel of the image. The results obtained for the forests show that in the first year it occupied an area of 56.53%, which in 2019 increased to 59.59%, decreasing in 2020 with 56.08%, decreasing even more in 2021 with 53.12% and finally increasing in the last year with 60.77%. This process of decrease in the first years is due to the extension of agriculture and timber, which is the main source of income in the area. In recent years, the area of forest has increased by 4.24% compared to the initial year.
