Abstract Effective wildfire prevention includes actions to deliberately target different causes. However, the cause of an increasing number wildfires is unknown, hindering targeted efforts. We developed a machine learning model ignition across western United States on basis physical, biological, social, and management attributes associated with wildfires. Trained from 1992 2020 12 known causes, overall accuracy our exceeded 70% when applied out‐of‐sample test data. Our more accurately separated ignited by natural versus human causes (93% accuracy), discriminated among 11 classes human‐ignited 55% accuracy. attributed greatest percentage 150,247 for which source was unknown equipment vehicle use (21%), lightning (20%), arson incendiarism (18%).

Quantifying wildfire risk to the built environment in rural rangelands of the US Interior West

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1924)

Published: April 1, 2025

Fire increasingly conflicts with the built environment. The wildland–urban interface (WUI) describes areas where vegetation near environment increases wildfire hazard. In United States, attention concentrates on WUI in forested areas, but human populations are extending into rangelands. combination of expansion and woody plant encroachment might present novel challenges to management, especially given rural nature rangelands US, which extends response time emergency services. We use publicly available data describe abundance, distribution, type overall risk Most US Interior West (54%) occurs rangeland: majority is rangeland 4.3% that—over 1 million km 2 —is WUI. rural: 59% further than 10 from town tribal even more remote. Rangeland approximately twice as likely be degraded by non-WUI rangeland, suggesting that conventional fire suppression tactics for fuels insufficient or unsafe. Greater awareness help leverage community-level adaptive capacity against protecting lives property beyond urban/peri-urban zones.

Mapping wildfire hazard, vulnerability, and risk to Canadian communities

International Journal of Disaster Risk Reduction, Journal Year: 2023, Volume and Issue: 101, P. 104221 - 104221

Published: Dec. 24, 2023

Large and intense wildfires are an integral part of many Canadian landscapes, playing a critical role in ecosystem dynamics. However, the recent catastrophic fire seasons have highlighted threat that can pose to human communities. Identifying areas at higher risk is therefore crucial order mitigate impacts on society. This study presents standardized method for nationwide wildfire assessment, focusing buildings populations. Using Burn-P3 simulation model, along with building footprint census data, we generated hazard, vulnerability, maps Canada's forested regions. Our findings demonstrate nuanced understanding when considering interaction between hazard physical vulnerability. Approximately 32.3% 6.3% land classified as High Very high risk, respectively. We estimate 111,519 units (5.8%) directly exposed 10,622 (0.6%) risk. Moreover, found approximately 283,200 people reside while 30,500 live Indigenous on-reserve communities particularly vulnerable impact. 18.9% living reserves fire, compared only 2.4% non-reserve population. The present offers information development national management policy provides new insights support implementation effective measures reduction.

Physical, social, and biological attributes for improved understanding and prediction of wildfires: FPA FOD-Attributes dataset

Earth system science data, Journal Year: 2024, Volume and Issue: 16(6), P. 3045 - 3060

Published: June 28, 2024

Abstract. Wildfires are increasingly impacting social and environmental systems in the United States (US). The ability to mitigate adverse effects of wildfires increases with understanding social, physical, biological conditions that co-occurred or caused wildfire ignitions contributed impacts. To this end, we developed FPA FOD-Attributes dataset, which augments sixth version Fire Program Analysis Fire-Occurrence Database (FPA FOD v6) nearly 270 attributes coincide date location each ignition US. v6 contains information on location, jurisdiction, discovery time, cause, final size >2.3×106 US between 1992 2020 . For wildfire, added physical (e.g., weather, climate, topography, infrastructure), land cover normalized difference vegetation index), population density vulnerability administrative national regional preparedness level jurisdiction) attributes. This publicly available dataset can be used answer numerous questions about covariates associated human- lightning-caused wildfires. Furthermore, support descriptive, diagnostic, predictive, prescriptive analytics, including development machine learning models. is at https://doi.org/10.5281/zenodo.8381129 (Pourmohamad et al., 2023).

Dear Editor, The ongoing forest fires in Quito (Ecuador) have brought to light a pressing environmental and public health crisis [1]. As the rage on, we are witnessing detrimental effects on air quality, which is rapidly deteriorating due prolonged droughts. These fires, much like those experienced certain countries (e.g., UnitedStates, Australia, Portugal) recent years, pose serious threat vulnerable populations [2], particularly children adolescents [3].We know from past studies that exposure poor as seen during wildfire seasons, can lead significant issues [4], especially respiratory problems [5]. However, beyond immediate risks, these disasters also limit opportunities for physical activity, crucial healthy development of young people [6,7]. For instance, research Australian bushfires, example, demonstrated sharp decline activity levels among only when quality exceeded critical hazardous [6].In Quito, must be proactive ensuring mental well-being our youth protected times crisis. In I would offer some evidence-based recommendations help mitigate risks children's health:-Monitor closely: Families should regularly check local levels, wildfires present. Tools mobile applications or websites provide real-time data [8,9]. Google Maps Apple now include Air Quality Index (AQI) indicators lower corner map searching locations. Additionally, dedicated apps AirVisual, China Network (AQICN), IQAir, government platforms Ecuador's Ministry Environment, Water Ecological Transition) often accurate updates. By using tools, parents decide it safe their outdoors.On days poor, outdoor activities avoided prevent inhalation harmful particles [10].-Promote indoor activity: It essential maintain even indoors [11]. Parents encourage simple, lowcost require minimal equipment, such dancing music, creating obstacle courses with household items pillows, chairs, boxes), playing traditional games hopscotch hide-and-seek indoors.Additionally, free online resources, YouTube videos offering kidfriendly exercise routines yoga sessions, great way keep active without financial investment. health, extended periods [12].-Manage sedentary behavior: With reduced play, resort screen-based entertainment [13]. important establish daily balance screen time movement [12]. short activities, stretching exercises, break up long sitting. if permits, walking well-ventilated areas simple yet effective promote activity. Walking not helps reduce behavior but serves natural stress reliever [14], lowering depression anxiety [15] increasing psychological [16]. Encouraging brief family walks, small spaces hallways, could foster both well-being.-Prioritize sleep: Poor [7] increased [17] negatively affect sleep, vital [18].Parents ensure consistent bedtime routine, before bed, create quiet, comfortable environment sleep [19]. Maintaining regular schedules, weekends, regulate internal body clocks promotes restorative [20].Additionally, incorporating relaxing pre-sleep reading [21] listening calming music [22] further improve prepare restful night.-Mental support: accompany long-lasting [23]. educators vigilant emotional support [24], perhaps by meditation engage mentally while keeping them calm. effectively monitoring supporting requires knowledge training. Providing access workshops recognizing signs stress, modules first aid, empower respond appropriately. Schools communities partnerships professionals guidance supportive caregivers. Incorporating measures check-ins use validated screening tools Strengths Difficulties Questionnaire, SDQ [25]) identify who might need additional timely intervention.-Healthy eating: A balanced diet strengthen immune systems [26], [27].Providing nutrient-rich foods, fruits, vegetables, whole grains, lean proteins, fats, receive vitamins minerals needed growth resilience against illnesses.Foods rich antioxidants, berries leafy greens, combat inflammation caused [28], sources omega-3 fatty acids, fish walnuts, brain [29]. eating habits involving meal planning preparation, making fosters positive attitudes towards nutritious foods [30]. Promoting practices associated decreased enhancing overall well-being.-Prepare disaster kits: part preparedness, families consider updating kits resources [31]. addition essentials water, food, aid supplies, engaged crises [32]. Examples coloring books, puzzles, age-appropriate games, resistance bands, objects balls sensory toys.Encouraging pack sense involvement security, challenging situations [33]. although supply widely recommended at national level, necessary better understand role survival rates after events [34].The situation reminder broader challenges face climate change its impact [35].
