Megafires of 2020 in Córdoba: Fire incidence in areas of ecological and socioeconomic value
In 2020, the Sierras of Córdoba suffered the most extreme fire season in recent collective memory, causing severe ecological and socioeconomic damage. In this study, we mapped the fires of 2020 using Sentinel 2 imagery, we compared the season with historical statistics from 1987-2019 in terms of number of fires, burned area, fire size distribution and fire frequency. Additionally, we analyzed fire incidence in areas of ecological value (protected natural areas [PNA], priority areas for biodiversity conservation [CPA] and native forests protected by Federal Law [#26331/07]) and in areas of socioeconomic value (productive and residential lands, considering their tax value). In 2020, nearly 291866 ha burned in the Sierras of Córdoba —becoming the fire season with the second largest burned area in 34 years—, with a record of 5 megafires (≥10000 ha). Many burned areas had fire return intervals from 3 to 9 years on average, constituting as hotspot regions of fire in our study area. Flames affected more than 5% of PNA, 12% of CPA and 12% of forests protected by federal law. Fires affected mainly the rural areas, and to a lesser extent, urban lands with tax values of AR$8677 and 24592 million, respectively. Extreme drought and fuel availability were determinants for the occurrence of megafires, while the pandemic lockdown suggests that fires were not set by negligent urban inhabitants. The damages caused by the 2020 megafires and the possibility of similar scenarios in the future require policies towards an integral management of the fire issue in Córdoba province.

En el año 2020, las Sierras de Córdoba registraron la temporada de incendios más extrema de la memoria colectiva reciente, con daños ecológicos y socioeconómicos severos. En este trabajo se cartografiaron los incendios de 2020 utilizando imágenes Sentinel 2, se comparó la temporada con estadísticas históricas en función del número de incendios, la superficie quemada, la distribución del tamaño de los incendios y la frecuencia en relación con el período 1987-2019. También se analizó la incidencia del fuego en áreas de valor ecológico (áreas naturales protegidas [ANP], áreas prioritarias para la conservación [APC] y áreas de bosque nativo protegidas por la Ley de Bosques [Ley Nacional 26331/07]) y en áreas de valor socioeconómico (tierras destinadas a usos productivos y residenciales, considerando su valor fiscal). En 2020 se quemaron 291866 ha en las Sierras de Córdoba, constituyéndose en la segunda temporada de incendios con mayor superficie quemada en 34 años, con 5 megaincendios (≥10000 ha). Muchas áreas quemadas presentaron recurrencias de fuego entre 3 y 9 años en promedio, lo que las hace áreas hotspot de fuego en las sierras. Las llamas afectaron más del 5% del territorio declarado como ANP, 12% de las APC y 12% de los territorios protegidos por la Ley de Bosques. El fuego afectó principalmente parcelas rurales y, en menor medida, urbanas, con un valor fiscal de AR$8677 y 24592 millones, respectivamente. La sequía extrema y la disponibilidad de combustible determinaron la ocurrencia de los megaincendios, mientras que el contexto de pandemia —con restricciones a la circulación de personas— sugiere que los incendios no fueron originados por habitantes urbanos negligentes. Los daños ocasionados por los megaincendios y la posibilidad de escenarios similares a futuro demandan avanzar hacia un manejo integral de la problemática del fuego en la provincia de Córdoba.
