description | The climate inthe province of Córdoba has suitable conditions for the occurrence of firesannually. The impact of current drought and preceding humidity conditions on fire activity was analyzed and modeled for the main eco-regions of the center of the country by using the Palmer Drought Severity Index (PDSI). A statistically significant relationship was observed between fires and droughts forthe same season, while preceding weather conditions played a relatively minor role, depending on the region. A fire frequency map for the period 2001-2020 was created from the MODIS burned area product MCD64A1.The mountain region was the most affected in terms of burned area andthe fire frequency ranged from 1 to 6 times. Furthermore, the models presented here estimated a positive response of fire occurrence to higher humidity conditions in the previous year. The Bañadosdel Río Dulce region had the highest fire occurrence and frequency, with sites burnedup to 11 times. The models presented for the individual eco-regions are robust enough for developing a seasonal forecasting system to support fire management strategies. |

El clima de la provincia de Córdoba ofrece,anualmente, condiciones predisponentes para la ocurrencia de incendios. Se analizó y modeló el impacto de la sequía mensual y las condiciones de humedad precedente en la actividad de los incendios para las principales ecorregiones del centro del país, a partir del índice de severidad de sequía de Palmer (PDSI).Se creó un mapa de frecuencia de incendios para el período 2001-2020 a partir del producto de área quemada MCD64A1 de MODIS. Se observó una relación estadísticamente significativa entre los incendios y las sequías de la misma temporada, mientras que las condiciones climáticas precedentes jugaron un papel relativamente menor, según la región. Laregión serrana fue la más afectada en términos de superficie quemada y la frecuencia de incendios varió entre una y seis veces. Además, los modelos aquí presentadosestimaron una respuesta positiva de la ocurrencia de incendios ante condiciones de mayor humedad en el año anterior. La región Bañados del Río Dulce obtuvo la mayor ocurrencia y frecuencia de incendios, con sitios que se quemaron hasta 11 veces. Los modelos presentados para lasecorregiones individuales son prometedores para desarrollar un sistema de pronóstico estacional que respalde las estrategias de manejo de incendios.
