- Abstract
Deforestation is a worldwide problem in watersheds, caused by anthropogenic activities that have been developed since colonization until today, producing large areas of deforested forests. The objective of this research was to determine deforestation through remote sensing in the hydrographic basins of the Portoviejo - Chone River. The geographic information system and the remote sensing technique with Landsat and Spot satellite images with a spatial resolution of 30 meters available for the study were used as an analysis tool. Finally, a total deforestation rate of the basins was obtained from 1998 to 2014 with a deforested forest area of 16,55% in the 16 years evaluated. The land use coverage classification of the basins was carried out using supervised classification where field verification was carried out for the identification of land cover and corroboration in satellite images. Subsequently, it was determined that the vegetation cover of the hydrographic basins for the period 1998-2000 is 332 782 ha, while for the period 2000-2008 a forest area of 241 167 ha was obtained, while for the period 2008-2014 is 331 728 ha. Furthermore, it was possible to obtain an overall reliability of the real and deduced coverage of 61,81%, which indicates that the land use classification of the hydrographic basins is admissible.
