Chubut.-Un investigador del CONICET utiliza informaci\u00f3n satelital para estudiar riesgos, amenazas y vulnerabilidad de los pastizales ante las quemas.<\/p>\n<\/div>\n

<\/p>\n

El fuego se propaga r\u00e1pidamente, a veces a una velocidad inusitada \u00bfSe puede llegar antes de que la llama se inicie? El investigador principal del CONICET del Instituto Patag\u00f3nico para el Estudio de los Ecosistemas Continentales (IPEEC) del Centro Nacional Patag\u00f3nico, H\u00e9ctor del Valle, trabaja en la evaluaci\u00f3n y monitoreo satelital de las emergencias ambientales como los incendios.\u00bbContar con cartograf\u00eda digital sistem\u00e1tica del \u00e1rea quemada, permite conocer los patrones espaciales de ocurrencia del fuego y adem\u00e1s realizar una evaluaci\u00f3n del impacto ambiental, as\u00ed como la introducci\u00f3n de medidas apropiadas para prevenir la erosi\u00f3n del suelo y ayudar a la regeneraci\u00f3n de la vegetaci\u00f3n\u201d, asegura Del Valle.<\/p>\n

\n

El equipo del trabajo que lidera Del Valle, cuenta desde el a\u00f1o 1981 con una valiosa base de datos digital de \u00e1reas quemadas. \u00abConocer las \u00e1reas propensas a la recurrencia de incendios, nos permiten visualizar las zonas donde el problema existe, y establecer las medidas de prevenci\u00f3n y control en estas \u00e1reas y sus adyacencias\u201d, asegura.<\/p>\n

Si bien las causas que originan un incendio se agrupan en tres categor\u00edas principales: intencionales, negligencia y naturales, determinadas condiciones regionales, vuelven a algunas zonas de la Patagonia, propensas al fuego.\u00bbEn las \u00faltimas d\u00e9cadas, en los alrededores de varias ciudades del noreste de la Patagonia, algunos establecimientos ganaderos han abandonado su actividad productiva por distintas razones, lo que ha producido un aumento relativo en la biomasa de pastos y arbustos, que al secarse durante el verano constituye un combustible altamente inflamable. Las altas temperaturas unidas a las bajas humedades relativas y vientos moderados a fuertes, tienden a aumentar el riesgo de incendio, ya sea motivado por causas naturales (fundamentalmente rayos) o provocados por el hombre. Es as\u00ed que desde entonces ha aumentado notoriamente la frecuencia en la ocurrencia de incendios en estos pastizales\u201d, describe Del Valle.<\/p>\n

En la actualidad, dada la cobertura de datos satelitales \u00f3pticos y radares permiten un monitoreo terrestre en tiempo real en las tres etapas de un siniestro (antes, durante y despu\u00e9s).\u00bbDe cada uno de ellos sabemos qu\u00e9 temperatura hab\u00eda el d\u00eda que ocurrieron, como eran las condiciones de viento, las caracter\u00edsticas de la vegetaci\u00f3n predominante antes del incendio o la humedad del combustible. Al recolectar todos estos datos podemos generar hip\u00f3tesis que puedan convertirse en potenciales alertas tempranas\u201d, afirma el investigador.<\/p>\n

Para el cient\u00edfico la informaci\u00f3n es una herramienta fundamental para combatir incendios. \u00abSe debe planificar y trabajar m\u00e1s en la prevenci\u00f3n. Nosotros generamos informaci\u00f3n b\u00e1sica (investigaci\u00f3n) que se transfiere a organismos que realizan la extensi\u00f3n. Nuestro objetivo es poder estar delante de los problemas y no detr\u00e1s\u201d asegura.
