Comparison of Particulate Air Pollution From Different Emission Sources and Incident Dementia in the US

JAMA Internal Medicine, Journal Year: 2023, Volume and Issue: 183(10), P. 1080 - 1080

Published: Aug. 14, 2023

Emerging evidence indicates that exposure to fine particulate matter (PM2.5) air pollution may increase dementia risk in older adults. Although this suggests opportunities for intervention, little is known about the relative importance of PM2.5 from different emission sources.

Communications Earth & Environment, Journal Year: 2023, Volume and Issue: 4(1)

Published: Sept. 5, 2023

Abstract In the province of British Columbia, Canada, four most severe wildfire seasons last century occurred in past 7 years: 2017, 2018, 2021, and 2023. To investigate trends activity fire-conducive climate, we conducted an analysis mapped perimeters annual climate data for period 1919–2021. Results show that after a century-long decline, fire increased from 2005 onwards, coinciding with sharp reversal wetting trend 20th century. Even as precipitation levels remain high, moisture deficits have due to rapid warming evaporative demand. Bottom-up factors further influence activity, legacy wildfires, insect outbreaks, land-use practices continually regimes. The compound effects climate-induced changes altered fuels now force Columbians confront harsh reality more frequent years intense prolonged activity.

Wildfires have emerged as one of the most destructive natural disasters worldwide, causing catastrophic losses. These losses underscored urgent need to improve public knowledge and advance existing techniques in wildfire management. Recently, use Artificial Intelligence (AI) wildfires, propelled by integration Unmanned Aerial Vehicles (UAVs) deep learning models, has created an unprecedented momentum implement develop more effective Although survey papers explored learning-based approaches wildfire, drone disaster management, risk assessment, a comprehensive review emphasizing application AI-enabled UAV systems investigating role methods throughout overall workflow multi-stage including pre-fire (e.g., vision-based vegetation fuel measurement), active-fire fire growth modeling), post-fire tasks evacuation planning) is notably lacking. This synthesizes integrates state-of-the-science reviews research at nexus observations modeling, AI, UAVs - topics forefront advances elucidating AI performing monitoring actuation from pre-fire, through stage, To this aim, we provide extensive analysis remote sensing with particular focus on advancements, device specifications, sensor technologies relevant We also examine management approaches, monitoring, prevention strategies, well planning, damage operation strategies. Additionally, summarize wide range computer vision emphasis Machine Learning (ML), Reinforcement (RL), Deep (DL) algorithms for classification, segmentation, detection, tasks. Ultimately, underscore substantial advancement modeling cutting-edge UAV-based data, providing novel insights enhanced predictive capabilities understand dynamic behavior.

Priority research directions for wildfire science: views from a historically fire-prone and an emerging fire-prone country

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

Published: April 1, 2025

Fire regimes are changing across the globe, with new wildfire behaviour phenomena and increasing impacts felt, especially in ecosystems without clear adaptations to wildfire. These trends pose significant challenges scientific community understanding communicating these changes their implications, particularly where we lack underlying evidence inform decision-making. Here, present a perspective on priority directions for science research—through lens of academic government scientists from historically wildfire-prone (USA) emerging (UK) country. Key topic areas outlined during series workshops 2023 were as follows: (A) predicting fire occurrence, impacts; (B) human ecosystem resilience fire; (C) atmospheric climate fire. Participants agreed focused research questions that seen gaps. was identified central connecting theme would allow critical advances be made all areas. findings provide one group perspectives feed into more transdisciplinary outline priorities diversity knowledge bases addressing under regimes.
