Caracterización de los patrones de incendios forestales y su relación con factores climáticos en la Sierra Centro-Ecuador

Etiketa erantsi | Gaia: | During the last years, forest fires have increased, affecting large extensions of natural areas and livelihoods; this increase may be due to the incidence of precipitation, that is, to the evident climatic variability. The objective of this research is to analyze the influence of climate on the occurrence of forest fires in the Sierra Centro of Ecuador from the period 2001-2020. The Global Precipitation Measurement (GPM) satellite products were used, which provide precipitation data sets, and Modis MCD64A1 version 6.1, which establishes the burned areas; data was processed with the help of the Google Earth Engine platform (GEE). 2020 presented the lowest value of accumulated precipitation, and the highest precipitation anomaly was identified. The Sierra Centro reported 29,825 ha affected by burning during the 2001-2020 period; however, in 2012, it presented a greater surface area affected by burning with 6,025 ha; in addition, Bolívar was the province most affected by burning with 9,030 ha during the period analyzed, while in the dry season July-August-September (JAS) 25,300 ha of burned areas were obtained. According to the statistical analysis, the dry period's accumulated precipitation presents a correlation based on the affected areas, while the anomalies do not present a correlation with the occurrence of forest fires (burnt areas). In addition, the multivariate ENSO index presented a significant correlation with the areas burned in the dry season. The Herbazal ecosystem has been the most affected with 6,310.83 ha by burning based on the calculation of the standardized value with burned areas. |
