Wildfires are a growing concern to society and the environment in many parts of the world. Within the United States, the land area burned by wildfires has steadily increased over the past 40 years. Agricultural land management is widely understood as a force that alters fire regimes, but less is known about how wildfires, in turn, impact the agriculture sector. Based on an extensive literature review, we identify three pathways of impact-direct, downwind and downstream-through which wildfires influence agricultural resources (soil, water, air and photosynthetically active radiation), labour (agricultural workers) and products (crops and livestock). Through our pathways framework, we highlight the complexity of wildfire-agriculture interactions and the need for collaborative, systems-oriented research to better quantify the magnitude of wildfire impacts and inform the adaptation of agricultural systems to an increasingly fire-prone future.
野火是世界上许多地区社会和环境日益关注的问题。在美国,过去 40 年来,野火燃烧的土地面积稳步增加。农业土地管理被广泛认为是改变火灾发生规律的力量,但人们对野火反过来如何影响农业部门知之甚少。基于广泛的文献综述,我们确定了三种影响途径——直接途径、下风途径和下游途径——通过这些途径,野火会影响农业资源(土壤、水、空气和光合有效辐射)、劳动力(农业工人)和产品(作物和牲畜)。通过我们的途径框架,我们强调了野火与农业相互作用的复杂性,以及需要进行协作的、面向系统的研究,以更好地量化野火影响的规模,并为农业系统适应越来越多的火灾频发的未来提供信息。
