Remote-sensed forest fire activity across Mexico and its sensitivity to drought
Forest fires in México are natural regulators in the dynamics of forest ecosystems. However, their mismanagement can cause catastrophic consequences, affecting critical elements of the ecosystems where they occur.

| description | Forest fires in México are natural regulators in the dynamics of forest ecosystems. However, their mismanagement can cause catastrophic consequences, affecting critical elements of the ecosystems where they occur. In recent years, official sources have reported an increase in forest fires and affected area. It is very well known that forest fires are widely linked to climatic phenomena. Therefore, the main objective of this study is to evaluate the relationship between drought and fire occurrence in Mexico during the period 2005-2016. The fire data were obtained from Moderate Resolution Imaging Spectroradiometer (Modis) while the source of drought data is from a Standardized Index of Precipitation and Evapotranspiration (SPEI). Through the G statistic of Getis-Ord it was geospatially determined where the highest incidence of fires occur and where the largest affected area is located. Results indicated that fires are clustered in the center of the country along the Sierra Madre del Sur and the Eje Neovolcánico. It is also concluded that the drought is related to the occurrence of forest fires and their affected surface by 32% and 38% respectively. This study contributes to recent research linking the influence of climate phenomena with fire. |

Los incendios forestales en México son reguladores naturales en la dinámica de los ecosistemas forestales. Sin embargo, su mala gestión puede causar consecuencias catastróficas, que afectan a los elementos de los ecosistemas donde se presenten. Fuentes oficiales indican un incremento en los últimos años en su ocurrencia y en la superficie afectada. Estudios recientes indican que los incendios forestales están estrechamente vinculados a fenómenos climáticos. Por lo tanto, el objetivo principal de este trabajo fue evaluar la relación entre la sequía y la ocurrencia de incendios en México durante el período 2005-2016. Los datos de fuego se obtuvieron del espectrorradiómetro de imágenes de resolución moderada (Modis, por sus siglas en inglés) mientras que los datos de sequía se fundamentaron en el índice estandarizado de precipitación y evapotranspiración (SPEI). A través del estadístico G de Getis-Ord se determinó geoespacialmente donde se ubica la mayor incidencia de incendios forestales y la mayor área afectada. Se observó que los incendios se agrupan en el centro del país a lo largo de la Sierra Madre del Sur y en el Eje Neovolcánico. Además, se concluye que la sequía se ve relacionada con la ocurrencia de incendios forestales y su superficie afectada en 32% y 38% respectivamente. Este estudio contribuye a investigaciones recientes que relacionan la influencia de los fenómenos climáticos con el fuego.
