Abstract
Coastal wetlands face the growing problem of altered fire regimes that compromise ecosystem structures and functions, as well as the ecosystem services from which society benefits. In this review of the state of fire management research in coastal wetlands, we identified 81 publications on the topic over the last 35 years. Most studies analyzed the relationships between fire and ecosystems using geospatial tools and were conducted in swamps, marshes, savannas, mangroves, dunes and hammock forests. Productive activities in the coastal zone like agriculture, cattle ranching, and hunting as well as the increased demand of water for human consumption directly or indirectly favor a rise in both the frequency and intensity of fires in coastal wetlands. In addition to the local impacts of this altered regime, there are synergistic effects with alterations in the hydrological regime, land use changes and atmospheric changes that increase the susceptibility to unwanted fire in these ecosystems. We emphasize the need to move towards focuses that adopt a socio-ecological and interdisciplinary perspective to conserve and restore the fire regimes in coastal wetlands.
Resumen
Los humedales costeros se enfrentan al creciente problema de la alteración de los regímenes de incendios que comprometen las estructuras y funciones de los ecosistemas, así como los servicios ecosistémicos de los que se beneficia la sociedad. En esta revisión de la investigación sobre el manejo del fuego en los humedales costeros, identificamos 81 publicaciones de los últimos 35 años sobre esta temática. La mayoría de los estudios analizaron las relaciones entre el fuego y los ecosistemas utilizando herramientas geoespaciales y se realizaron en pantanos, marismas, sabanas, manglares, dunas y petenes. Las actividades productivas en la zona costera como la agricultura, la ganadería y la caza, así como el aumento de la demanda de agua para el consumo humano, favorecen directa o indirectamente el aumento de la frecuencia e intensidad de los incendios en los humedales costeros. Además de los impactos locales de la alteración al régimen, existen efectos sinérgicos con las alteraciones del régimen hidrológico, los cambios en el uso del suelo y los cambios atmosféricos que se combinan para aumentar la susceptibilidad al fuego no deseado en estos ecosistemas. Insistimos en la necesidad de avanzar hacia enfoques que adopten una perspectiva socio-ecológica e interdisciplinar para conservar y restaurar los regímenes de fuego en los humedales costeros.
