Evaluación De Incendios en Áreas Periurbanas De La Ciudad De Corrientes (Argentina) Durante El Año 2020

Abstract

Prevention and early warning of risks related to climate variability are essential to minimize the manifestation of a certain risk. However, given the impossibility of preventing this from occurring, it is equally important to monitor the threat, both spatially and temporally. In this sense, extreme drought events in the northeastern region of Argentina during 2020, added to cultural practices and poor fire management, have generated significant sources of fires, affecting vast areas of the region. Given the above, the objective of the work is to measure and analyze the areas affected by the manifestation of fires in the periurban area of the city of Corrientes (Argentina), applying fire assessment tools with Google Earth Engine. It was possible to corroborate the veracity of the results while proposing a complimentary analysis methodology that allows obtaining information with greater precision. La prevención y alerta temprana de los riesgos vinculados a la variabilidad climática, son fundamentales para reducir al máximo la manifestación de un determinado riesgo. No obstante, ante la imposibilidad de impedir que este ocurra, es de igual importancia realizar un seguimiento, tanto espacial como temporal de la amenaza. En este sentido, los eventos extremos de sequía en la región del nordeste argentino durante el año 2020, sumado a prácticas culturales y el mal manejo del fuego, han generado significativos focos de incendios, afectando vastas superficies de la región. Ante lo expuesto, el objetivo del trabajo es medir y analizar las zonas afectadas por la manifestación de incendios en el área periurbana de la ciudad de Corrientes (Argentina), aplicando herramientas de evaluación de incendios con Google Earth Engine. Se pudo corroborar la veracidad de los resultados, a la vez de proponer una metodología de análisis complementario que permita la obtención de información con mayor precisión.

Assessment of black and gold howler monkey (<i>Alouatta caraya</i>, Humboldt, 1812) populations in two new study sites in northeastern Argentina

“…Another long-term study site, Estación Biológica Corrientes (EBCo) (a mainland fragmented forest, 27°30'S, 58°41'W) has a density of 1.04 individuals/ ha (Kowalewski and Zunino, 2004;Zunino et al, 2007;Kowalewski et al, 2019). EBCo and RLL have similar forest structure and composition, however EBCo has suffered intense deforestation and habitat modification through the years, and was recently further damaged by massive fires in late 2020, where half of the A. caraya groups died (Heidt, 2020;Smichowski et al, 2021). In 2020-2022, fires affected a large part of Corrientes province, including areas with populations of A. caraya where numerous individuals died in the fires or escaping from fires (Heidt, 2020).…”

Application of Google Earth Engine in the preliminary analysis of fire severity in the Iberá National Park and Reserve, Argentina

“…Fires, both those of natural and anthropogenic origin, are one of the most aggressive and sudden disturbances that can affect ecosystems, strongly depleting and modifying their structure and composition, and their impact can be reflected both locally and globally (Peña & Ulloa, 2017;Montiel et al 2021;Smichowski et al 2021;Díaz et al 2023). Their manifestation, especially those of large magnitude, affect the natural evolution of ecosystems directly, and biogeochemical cycles, local climate and other variables indirectly (Crutzen & Andreade, 1990;Hoffmann et al 2003).…”

“…However, the consequences of this type of disturbance are not always negative, since in many regions it plays a key ecological role by contributing to ecosystem balance (Ferrelli, 2023;Kunst et al 2015). In turn, in certain regions fire is used as a tool for vegetation management and clearing (Smichowski et al 2021). As mentioned by Soares et al (2021), in some cases sexual reproduction of plants is favored by enhancing post-fire flowering or facilitating fruit spreading, releasing seeds (Lamont et al 2019), as long as they can survive the fire event (Cirne & Miranda, 2008).…”

“…In recent years, fires have been recurrently manifested in South America, and the Argentine territory is an example of this (Delegido et al 2018;Smichowski et al 2021). During 2020, fires were recorded in 22 of the 23 provinces that comprise the Argentine national territory (MAyDS, 2020).…”

“…During 2020, fires were recorded in 22 of the 23 provinces that comprise the Argentine national territory (MAyDS, 2020). The province of Corrientes was affected by a large number of fire outbreaks distributed throughout the territory, with around 20 % of the peri-urban area of the city being burned (Smichowski et al 2021).…”
