Incendios forestales, regulación de inundaciones, depuración de aguas, severidad, restauraciónResumen
Los incendios forestales son un fenómeno global con repercusiones positivas y negativas en los ecosistemas. Estos son un elemento natural de los ecosistemas que dio forma a diversos biomas. Sin embargo, durante algún tiempo, pueden perturbar los ecosistemas, reduciendo su capacidad para suministrar diversos servicios. El objetivo de este artículo es resumir los impactos de los incendios forestales en la regulación de las inundaciones y la depuración del agua y discutir el uso de algunas medidas de restauración para mitigar los impactos de los incendios forestales. Los incendios forestales, especialmente en el periodo inmediatamente posterior al evento, reducen la capacidad del ecosistema para regular las inundaciones y depurar el agua debido a la eliminación de vegetación y cenizas que pueden degradar la calidad de ese agua. La magnitud de los impactos depende esencialmente de la severidad del incendio forestal y de la intensidad de las precipitaciones posteriores al mismo. Deben aplicarse medidas de restauración, especialmente después de incendios forestales de gran severidad y si la recurrencia es elevada. En el contexto del cambio climático, se espera que el intervalo entre incendios sea más corto y que la severidad sea mayor. Por lo tanto, las medidas de restauración pueden ser más necesarias.
