Published: May 20, 2024

Forest fires have emerged as a significant global concern, exacerbated by both warming and the expanding human population. Several adverse outcomes can result from this, including climatic shifts greenhouse effects. The ramifications of fire incidents extend widely, impacting communities, financial resources, natural environment, warming. Therefore, timely detection is essential for quick effective response not to endanger forest animal life, economy. This study introduces approach utilizing transfer learning with YOLOv8 (You Only Look Once version 8) pretraining model TranSDet model, which integrates an improved deep algorithm. Transfer Learning based on pre-trained YoloV8 enhances fast accurate object aggregate structure detect small fires. Furthermore, train we collected 5200 images performed augmentation techniques data, such rotation, scaling, changing due saturation. Small be detected distance our suggested during day at night. Objects similarities lead false predictions. However, dataset technique reduces feasibility. experimental results prove that proposed successfully achieve 98% accuracy minimize catastrophic incidents. In recent years, advancement has enhanced safety secure environments. Lastly, conducted comparative analysis method’s performance widely used evaluation metrics validate achieved results.

Wildfire Risk Assessment in Ambato, Ecuador: Drought Impacts, Fuel Dynamics, and Wildland–Urban Interface Vulnerability

Fire, Journal Year: 2025, Volume and Issue: 8(4), P. 130 - 130

Published: March 27, 2025

Wildfires represent an increasing threat to ecosystems and communities, driven by climate change, fuel dynamics, human activities. In Ambato, Ecuador, a city in the Andean highlands, these risks are exacerbated prolonged droughts, vegetation dryness, urban expansion into fire-prone areas within Wildland–Urban Interface (WUI). This study integrates climatic, ecological, socio-economic data from 2017 2023 assess wildfire risks, employing advanced geospatial tools, thematic mapping, machine learning models, including Multinomial Logistic Regression (MLR), Random Forest, XGBoost. By segmenting area 1 km2 grid cells, microscale risk variations were captured, enabling classification five categories: ‘Very Low’, ‘Low’, ‘Moderate’, ‘High’, High’. Results indicate that temperature anomalies, reduced moisture, anthropogenic factors such as waste burning unregulated land-use changes significantly increase fire susceptibility. Predictive models achieved accuracies of 76.04% 77.6% (Random Forest), 76.5% (XGBoost), effectively identifying high-risk zones. The highest-risk found Izamba, Pasa, San Fernando, where over 884.9 ha burned between 2023. year 2020 recorded most severe season (1500 burned), coinciding with extended droughts COVID-19 lockdowns. Findings emphasize urgent need for enhanced regulations, improved firefighting infrastructure, community-driven prevention strategies. research provides replicable framework assessment, applicable other regions beyond. integrating data-driven methodologies policy recommendations, this contributes evidence-based mitigation resilience planning climate-sensitive environments.

Assessment of Forest Fire Impact and Vegetation Recovery in the Ghalahmah Mountains, Saudi Arabia

Fire, Journal Year: 2025, Volume and Issue: 8(5), P. 172 - 172

Published: April 30, 2025

Forest fires are a critical ecological disturbance that significantly impact vegetation dynamics, biodiversity, and ecosystem services. This study investigates the impacts of forest in Ghalahmah Mountains, Saudi Arabia, using remote sensing data fire models to assess severity, environmental drivers, post-fire recovery. The research integrates Landsat 8, Sentinel-2, DEM analyze spatial extent severity 2020 event Relativized Burn Ratio (RBR). Results reveal high-severity burns covered 49.9% affected area, with pre-fire density (NDVI) moisture (NDWI) identified as key drivers through correlation analysis Random regression. Post-fire recovery, assessed NDVI trends from 2021 2024, demonstrated varying recovery rates across types. Medium areas (0.2–0.3) recovered fastest, 134.46 hectares exceeding conditions by while high (>0.3) exhibited slower 26.55 still recovering. These findings underscore resilience grasslands shrubs compared dense woody vegetation, which remains vulnerable fires. advances ecology combining multi-source machine learning techniques provide comprehensive understanding processes semi-arid mountainous regions. results suggest valuable insights for sustainable land management conservation, emphasizing need targeted fuel protection ecologically sensitive areas. contributes broader supports efforts management.

Climate Change and Human Health in the Arctic: A Review

Climate, Journal Year: 2024, Volume and Issue: 12(7), P. 89 - 89

Published: June 22, 2024

Over recent decades, the Arctic has begun facing a range of climate-related challenges, from rising temperatures to melting ice caps and permafrost thaw, with significant implications for ecosystems human well-being. Addressing health impacts these issues requires comprehensive approach, integrating scientific research, community engagement, policy interventions. This study conducts literature review assess effects climate change on in northern latitudes compile adaptation strategies countries. A search was performed between January April 2024 papers published after 2000, using electronic databases Web Science, Pubmed, Science Direct, Scopus, Google Scholar, eLibrary.RU, specific questions formulated direct search: (i) What are changes? (ii) How does affect health? (iii) measures policies required? The key phrases “climate change”, “human health”, “adaptation practices”, “Arctic” were employed searching. Ultimately, 56 relevant studies identified, reviewing risks such as infectious diseases, mental issues, diseases connected extreme weather events; wildfires their associated pollution; degradation; pure water; food quality. paper also examines mitigation at all levels governance, emphasizing need international cooperation action combat negative outcomes, investments healthcare infrastructure, emergency preparedness, public education. Incorporating diverse perspectives, including Indigenous knowledge, Community-Based Adaptation, EcoHealth One Health approaches, is crucial effectively addressing change.

The Arctic Ocean Nitrogen Cycle

Journal of Geophysical Research Biogeosciences, Journal Year: 2024, Volume and Issue: 129(7)

Published: July 1, 2024

Abstract Although the Arctic Ocean is small, its shallow shelves and highly productive coastal waters make it an important component of global biogeochemical cycling, especially nitrogen (N). Because inorganic forms dissolved N exist in so many different oxidation states, cycling can be quite complex. In this review, we describe current understanding major conduits bringing into surface as well key physical biological processes that are responsible for transformation from one form to another. We also discuss environmental factors currently controlling these transformations how may change a future Arctic.
