Au cours des 50 derni\u00e8res ann\u00e9es, l\u2019activit\u00e9 des feux de for\u00eat a chang\u00e9 au Canada en raison de plusieurs facteurs naturels et anthropiques, dont les changements climatiques, l\u2019utilisation des terres et les pratiques de gestion des incendies. Au Canada, la priorit\u00e9 absolue en mati\u00e8re de gestion des incendies est de prot\u00e9ger les personnes et les biens.<\/p>\n

Dans une \u00e9tude publi\u00e9e r\u00e9cemment dans la revue Nature Communications<\/a> (en anglais seulement), des chercheurs de Ressources naturelles Canada ont tent\u00e9 de savoir si des d\u00e9cennies de vigoureuse lutte contre les incendies ont r\u00e9duit les risques d\u2019incendie. Les peuplements forestiers plus jeunes (< 30 ans) sont g\u00e9n\u00e9ralement moins inflammables que les plus anciens, et une plus grande proportion de for\u00eats anciennes \u00e0 proximit\u00e9 des secteurs habit\u00e9s peut augmenter le risque de feu de v\u00e9g\u00e9tation. Pour mener cette \u00e9tude, les chercheurs ont compar\u00e9 le pourcentage de la superficie de for\u00eats r\u00e9cemment br\u00fbl\u00e9es dans un rayon de 25 km autour des agglom\u00e9rations avec le pourcentage au-del\u00e0 de cette distance, plus loin des localit\u00e9s.<\/p>\n

Leur analyse portait sur 160 agglom\u00e9rations r\u00e9parties dans la for\u00eat bor\u00e9ale du Canada et a d\u00e9montr\u00e9 que plusieurs d\u2019entre elles sont plus sujettes aux feux de v\u00e9g\u00e9tation parce qu\u2019elles sont entour\u00e9es par des for\u00eats plus anciennes et plus inflammables. Selon leurs recherches, des politiques vigoureuses de lutte contre les incendies ont probablement contribu\u00e9 \u00e0 accro\u00eetre la maturit\u00e9 des for\u00eats et la quantit\u00e9 et la continuit\u00e9 des combustibles forestiers.<\/p>\n

Cette \u00e9tude r\u00e9it\u00e8re la n\u00e9cessit\u00e9 d\u2019adopter une approche plus globale de la gestion des feux de for\u00eat, qui n\u2019est pas seulement ax\u00e9e sur la protection de la vie humaine et des biens, mais limite aussi la continuit\u00e9 des for\u00eats plus anciennes et hautement inflammables.<\/p>\n
