| description | The term mega-fire refers to ignitions of great extension with considerable environmental and socio-economic impacts. The present paper investigates the spatial and temporal dynamics of mega-fires and their causes and effects in Mexico over the last two decades. In this country, the mega-fire phenomenon has received little attention to date. The spatial distribution of mega-fires and the burned areas were analyzed through a geographical information system and the databases of the Global Fire Atlas and the National Forestry Commission, whereas the socio-economic impacts were identified by a review of newspaper sources. The results show that fires with an affected area of 500 to 1000 hectares are frequent almost all over the country, while events of more than 10 000 hectares are rare and concentrated mainly in the northern states. The number of mega-fires in Mexico is minimal compared to all wildfires registered nationally. However, they make up a large proportion of the burned areas, 45.8%, according to the database of the National Forestry Commission, and 58%, according to the Global Fire Atlas, for fires larger than 500 ha. The direct cause, in most cases, has an anthropogenic origin, yet an important number of mega-fires are caused naturally, especially in the north of the country. Regarding socio-economic effects, these phenomena produce a significant proportion of the costs and damages. |

Los megaincendios se refieren a igniciones forestales de gran magnitud con marcados impactos ambientales y socioeconómicos. El presente artículo investiga la dinámica espacial y temporal de la ocurrencia de megaincendios y sus causas y efectos en las últimas dos décadas en México, donde este fenómeno ha sido poco explorado. Mediante un sistema de información geográfica y las bases de datos del Global Fire Atlas y de la Comisión Nacional Forestal se analizó la distribución espacial de la ocurrencia y superficie afectada; mientras que los impactos socioeconómicos se identificaron a partir de la revisión de fuentes hemerográficas. Los resultados demuestran que incendios de más de 500 ha y 1000 ha son frecuentes en casi todo el país, pero los eventos de más de 10 000 hectáreas son escasos y se concentran principalmente en los estados del norte. El número de megaincendios en México es mínimo en comparación con el total de incendios registrados a escala nacional. Sin embargo, abarcan gran parte de la superficie afectada, 45.8% según los datos de la Comisión Nacional Forestal y 58% según el Global Fire Atlas para los incendios en superficies mayores a 500 ha. La causa directa en la mayoría de los casos es de origen antropogénica, aunque existe una porción importante de megaincendios que resultaron de causas naturales, sobre todo en el norte del país. Con respecto a los efectos socioeconómicos estos fenómenos también abarcan un porcentaje significativo de los costos y daños generados.
