Summary: Forest fires and dust storms are significant sources of atmospheric pollutants, but their monitoring and pollution-reducing measures are not widely recognized worldwide. This study used remote sensing techniques to analyze air pollution caused by forest fires and dust storms in Pakistan. High levels of absorbing aerosols, such as dust, smoke, and mixed aerosols, were observed in central, eastern, and southeastern Pakistan. Dust aerosols were abundant in southwestern and central/southern Pakistan. Concentrations of NO2, CO, and HCHO were high during forest fire breakouts in central, eastern, and northeastern Pakistan. Air masses from northwestern Pakistan carried pollutants to eastern, northeastern, and southern Pakistan. These findings have implications for air quality and forest management in Pakistan.

Summary: This study evaluated the land cover dynamics in western Chilean Patagonia and found that there was a loss of approximately 32,600 ha of old-growth forest and a recovery of approximately 69,000 ha of second-growth forest following the fires. However, around 61% of the area could potentially remain as intact forest landscape after the fires. This study provides the first evidence of the landscape state in western Patagonia after more than six decades since the large-scale fires.

Summary: Secondary vegetation in Fishbone pattern consistently increases over time, while Geometric pattern shows more secondary vegetation with more than 30 years old. Fishbone pattern has a more scattered spatial distribution of secondary vegetation and consistently reduces forest patch isolation. This indicates that the Fishbone pattern of deforestation produces a more biodiversity-friendly landscape structure than the Geometric pattern.

Summary: In this study, different machine learning models (Cu, RF, SVM, GPR) were used to predict soil phosphorous sorption parameters (PSPs). The results showed that using topographic attributes alone was not sufficient for accurate prediction of PSPs, but combining remote sensing data with soil properties reliably predicted PSPs. The RF model had the lowest RMSE values for MBC, the SVM model for PBC, the Cubist model for SPR, and the RF model for SBC. The study concluded that remote sensing data was an easily obtainable dataset that could reliably predict PSPs in the study area.

Summary: The postfire recovery of fire-adapted forests is uncertain due to changing climate and fire regimes. This study examines the extent and characteristics of poor forest recovery 30 years after the 1988 Yellowstone fires using remotely sensed data and the Normalized Difference Vegetation Index (NDVI). The results show that sparse and reduced forest recovery occupied a significant portion of the burned area, with vegetation in these areas being shorter and non-evergreen biomass being higher compared to recovered forest. Environmental characteristics such as elevation, slope, and distance from seed sources played a role in explaining the distribution and patch size of poor recovery areas. These findings highlight the importance of long-term monitoring and management strategies for postfire forest recovery.

Summary: Validation is crucial for assessing the quality of waterbody remote sensing products, and in situ data of waterbody parameters play a vital role in this process. A prediction model was developed based on in situ data from Taihu Lake to determine the representativeness of the measurements for validating remote sensing products. Key environmental variables affecting chlorophyll-a and total suspended solids were identified and a generalized regression neural network model showed the highest prediction accuracy. Testing results demonstrated the effectiveness of the model in screening in situ data and determining the time window for satellite-ground data matching.

Summary: This study evaluated the differences in diversity, similarity, and floristic and structural characteristics of woody savanna and forest formations in the Cerrado, affected and unaffected by fire. Fire-affected Cerrado had lower diversity, density, and dominance compared to the unaffected Cerrado, with similarities between treatments at different inclusion levels. Fire-affected Forest had smaller differences in diversity, density, and dominance than the unaffected Forest. The forest formation was similar at the highest inclusion level and in the total area, but dissimilar at lower levels. Lower density and diversity at lower inclusion levels were associated with fire-induced mortality.

Summary: The frequency and intensity of tropical cyclones in the North Atlantic Basin (NAB) have increased since the 1980s, with record-breaking seasons in 2017 and 2020. However, little is known about the response of coastal ecosystems, particularly mangroves in the Gulf of Mexico and the Caribbean, to these new climate norms at regional and subregional scales. This study analyzes 25 years of mangrove vulnerability and 24 years of short-term resilience in the NAB and subregions, using remote sensing-derived databases and machine learning techniques. The results highlight the variability in vulnerability and resilience rates, as well as the drivers behind them, emphasizing the importance of considering long-term climate trends and coastal development in the context of increasing cyclone activity.

Summary: High accuracy in timber volume estimation is essential for sustainable management of tropical forests. This study compared traditional methods and terrestrial laser scanners (TLS) for estimating stem variables in a secondary seasonal semideciduous forest. The results showed that TLS is a suitable method for obtaining tree structural variables in hyperdiverse secondary forests. However, occlusion of target trees by the regenerating understory and height estimates biased by crown characteristics should be taken into consideration.
