Abstract

The paper is aimed at assessing the associations between the road networks geography and dynamics of wildfire events in the East Siberian boreal forest. We examined the relationship between the function of roads, their use, and management and the wildfire ignition, propagation and termination during the catastrophic fire season of 2016 in the Irkutsk Region of Russia. Document analysis and interviews were utilized to identify main forest users and road infrastructure functional types and examine wildfire management practices. We combined community observations and satellite remotely sensed data to assess relationships between the location, extent and timing of wildfires and different types of roads as fire sources, barriers, and suppression access points. Our study confirms a strong spatial relationship between the wildfire ignition points and roads differentiated by their types with the highest probability of fire ignition near forestry roads and the lowest near subsistence roads. Roads also play an important role in wildfire suppression working as both physical barriers and access points for firefighters. Our research illustrates the importance of local and Indigenous observations along the roads for monitoring and understanding wildfires, including ‘zombie fires’. It also has practical implications for fire management collectively developed by authorities and local communities.
结合社区观测和遥感研究道路对东西伯利亚北部森林野火的影响
本文旨在评估东西伯利亚北方森林道路网络地理与野火事件动态之间的关联。我们研究了2016年俄罗斯伊尔库茨克地区灾难性火灾季节道路功能、使用和管理与野火点燃、传播和终止之间的关系。利用文件分析和访谈来确定主要的森林使用者和道路基础设施功能类型,并审查野火管理做法。我们结合社区观测和卫星遥感数据,评估野火的位置、范围和时间与不同类型的道路作为火源、障碍物和灭火入口之间的关系。我们的研究证实了野火点和道路之间存在着强烈的空间关系,根据其类型进行区分,森林道路附近的火灾发生概率最高,而生存道路附近的着火概率最低。道路在扑灭野火方面也发挥着重要作用,既是消防员的物理屏障,也是消防员的出入点。我们的研究表明了道路沿线的当地和土著观测对监测和了解野火(包括“僵尸火灾”)的重要性。它还对当局和当地社区共同制定的消防管理具有实际意义。

期刊介绍: Arctic Science is an interdisciplinary journal that publishes original peer-reviewed research from all areas of natural science and applied science & engineering related to northern Polar Regions. The focus on basic and applied science includes the traditional knowledge and observations of the indigenous peoples of the region as well as cutting-edge developments in biological, chemical, physical and engineering science in all northern environments. Reports on interdisciplinary research are encouraged. Special issues and sections dealing with important issues in northern polar science are also considered.
