Abstract

El The purpose of the study was to analyze the behavior of the normalized difference vegetation index of the communities of Warints and Yawi, located in the Limón Indanza canton, province of Morona Santiago, during the summer season. The methodology is descriptive, non-experimental and longitudinal, with 13 samples taken from June to September, from 1998 to 2022, taken from LandSat 5 and 8 of the TM and OLI sensors, respectively, with a cloud cover of 30%, the radiometric and atmospheric calibration was established and the NDVI was determined with ENVI 5.3. It was mapped in ArcGis 10.5, extracting the data for the application of statistical analysis (t Student at 5%). The average NDVI was 0.66, with maximum and minimum values of 0.925 and -0.033, respectively; with a negative trend line. It was concluded that a large part of the study area corresponds to native forest; however, the negative trend is due to anthropogenic activities and territorial growth of the communities. It is recommended to apply this study approach to explore and apply in similar areas.
