欧洲今年夏季遭遇历史性野火灾难，科学家指出这场危机并非简单由点火源引发，而是气候变化与森林管理不当共同作用的结果[1]。全球变暖改变了降水模式，增加大气含湿量导致冬季降水增多、春季干旱加剧，为大规模火灾创造了理想条件[1]。本轮火灾已释放近1800万吨二氧化碳[1]。
欧洲许多地区的单一树种林管理模式加剧了火灾蔓延的风险。法国Landes de Gascogne森林超四分之三为海洋松，这些树木由拿破仑三世在1857年下令种植[1]；葡萄牙桉树林占森林面积超四分之一[1]；西班牙约300万公顷前农田和牧场在佛朗哥时代（1939-1975）及之后被改种为快速生长的松树和桉树[1]。英国生态水文学中心陆面建模师Doug Kelley指出，"一些法国和西班牙的火灾发生在非常易燃的树种地区，这些树生长紧密，火焰传播非常快"[1]。
专家普遍认为防范需要多管齐下。FoRISK协调员Silvia Abruscato表示，"我们需要好好管理森林以避免如此大的灾难发生。所以预防、预防、预防"[1]。除了减少碳排放应对气候变化外，推进森林多样化和采取预防性森林管理措施被认为是降低未来火灾风险的关键[1]。
Europe faced a historic wildfire season this summer, with scientists attributing the escalating crisis not merely to ignition sources such as machinery and lightning, but fundamentally to the extreme conditions created by climate change.[1] Rising global temperatures have increased atmospheric moisture, resulting in heavier winter precipitation followed by intensified spring droughts—conditions that create an ideal environment for fires to ignite and spread.[1] The fires this season have already released approximately 18 million tons of carbon dioxide into the atmosphere.[1]
Beyond climate dynamics, widespread monoculture forest management across Europe has rendered many regions particularly vulnerable to rapid fire propagation. In France's Landes de Gascogne forest, over three-quarters of the area consists of maritime pine, a species planted on Napoleon III's orders in 1857.[1] Spain's situation is similarly problematic, with approximately 3 million hectares of former agricultural and pastureland converted to fast-growing pine and eucalyptus plantations during and after Franco's era between 1939 and 1975.[1] Portugal's eucalyptus forests account for more than one-quarter of the country's total forest area.[1] According to Doug Kelley, a land surface modeler at the UK Centre for Ecology & Hydrology, "some fires in France and Spain have occurred in areas with highly flammable tree species that grow densely together, causing flames to spread very rapidly."[1]
To mitigate future catastrophes, experts recommend a multi-pronged approach centered on emissions reduction, forest diversification, and preventive forest management practices.[1] Silvia Abruscato, coordinator of FoRISK, emphasized that "we need to manage forests well to prevent such large-scale disasters from occurring. So prevention, prevention, prevention" is essential.[1]
