Abstract

Background

Every year, people in Canada are evacuated due to wildland fires to avoid death, injury, and illness from fire and smoke events.

Aims

In this paper, we provide an overview of evacuations recorded in the Canadian Wildland Fire Evacuation Database between 1980 and 2021.

Methods

Our analysis covers evacuations in Canada from 1980 to 2021. We provide summary statistics including number of evacuations and evacuees, evacuation duration, seasonality, evacuation causes, community types, structure losses, and fatalities. We also investigate temporal and spatial patterns.

Key results

Between 1980 and 2021, there were 1393 wildland fire evacuation events with 576,747 people evacuated. During this period, there was an overall increase in frequency of evacuations, number of evacuees, and duration of events. Structure loss occurred during 194 evacuation events, with 4105 homes burned. We estimate wildland fire evacuations cost at least CAD3.7 billion (excluding structural losses), jumping to CAD4.6 billion if we include productivity losses. Indigenous peoples are disproportionately impacted in wildfire evacuations compared to the general Canadian population.

Conclusions

Wildland fire evacuations continue to occur across Canada and are increasing.

Implications

The findings from this study give us a better understanding of the characteristics of wildland fire evacuations, which can help guide emergency management.

1980 年至 2021 年加拿大野地火灾疏散情况
背景每年,加拿大都会发生野外火灾,人们为了避免火灾和烟雾造成的死亡、受伤和疾病而进行疏散。目的本文概述了加拿大野地火灾疏散数据库记录的 1980 年至 2021 年期间的疏散情况。方法我们的分析涵盖了 1980 年至 2021 年加拿大的疏散情况。我们提供了简要统计数据,包括撤离和撤离人数、撤离持续时间、季节性、撤离原因、社区类型、结构损失和死亡人数。我们还研究了时间和空间模式。主要结果1980 年至 2021 年期间,共发生了 1393 起野外火灾疏散事件,疏散人数达 576,747 人。在此期间,疏散频率、疏散人数和事件持续时间总体上都有所增加。在 194 次疏散事件中,有 4105 所房屋被烧毁,造成了结构性损失。我们估计,野地火灾疏散至少造成 37 亿加元的损失(不包括结构性损失),如果将生产力损失计算在内,则会增加到 46 亿加元。与加拿大总人口相比,原住民在野火疏散中受到的影响更大。结论加拿大各地的野火疏散仍在继续,而且还在增加。意义这项研究的结果让我们更好地了解了野地火灾疏散的特点,有助于指导应急管理。

期刊介绍: International Journal of Wildland Fire publishes new and significant articles that advance basic and applied research concerning wildland fire. Published papers aim to assist in the understanding of the basic principles of fire as a process, its ecological impact at the stand level and the landscape level, modelling fire and its effects, as well as presenting information on how to effectively and efficiently manage fire. The journal has an international perspective, since wildland fire plays a major social, economic and ecological role around the globe. The International Journal of Wildland Fire is published on behalf of the International Association of Wildland Fire.
