Uso de la Teledetección para Calcular el Carbono Secuestrado por el Bosque Municipal Protegido -Quito.

Abstract

Green areas in cities provide important ecosystem services such as carbon capture and heat wave control. This work investigates how much CO2 is stored in the trees of the protected municipal forest - Quito. The first phase calculated the Normalized Differential Vegetation Index from the year 2002 to the year 2030 using an image from the Lansat 8 satellite and the QGIS software, using linear regressions. The second phase was developed by obtaining a satellite image from SENTINEL-2 with which a mathematical model was established to determine the CO2 that each pixel visually represents.The third phase was the field study, with in situ information in a breakdown of 15 quadrants of 10 by 10 meters. In each quadrant the DBH and total height of the existing trees were measured. From this data, the amount of CO2 fixed by each quadrant is established. Field and satellite data were compared to find differences and compare with results obtained by other authors in different areas of Ecuador and South American countries. The contribution of the studied forest in compensating the city's emissions was determined.
