Summary: Proxy-based reconstructions in East Asia have shown mixed signatures of summer temperature and precipitation, driven by the East Asian Summer Monsoon. This study presents a reconstruction of a 3000-year fire and vegetation history in central Korea, revealing two fire episodes and varying climate conditions over the past two millennia. The dry periods were coincident with increased El Nino-Southern Oscillation in the Tropical Pacific Ocean, highlighting its role in controlling the hydroclimate of the Korean Peninsula. The potential value of further research on the climatic consequences of the Millennium Eruption of Mount Paektu/Changbaishan (946 CE) in the East Asian region is also emphasized.

Summary: A distinct ecotonal tree community was found in a forest-savanna mosaic landscape in Central Africa, acting as a buffer against fire spreading into the forest and contributing to landscape stability. This community is comprised of forest pioneer species and plays a crucial role in the preservation of the forest-savanna mosaic.

Summary: Research on sedimentary pollen and charcoal from northernmost Patagonia in Chile indicates significant changes in the distribution and abundance of Araucaria araucana during the Holocene, likely influenced by climate change and human activities. Increased fire activity and land use by American Indians coincided with the expansion of Araucaria, highlighting the potential management of this species in a human-altered landscape.

Summary: In landscapes with high and medium fire frequencies, savannas and forests exhibit a distinct bimodal distribution in functional trait space, indicating sharp functional differences between them. The stability of savannas relative to forests increases abruptly with higher fire frequencies, while functional differences between the two gradually intensify.

Summary: This study provides insights into the vegetation dynamics and fire history of Lago Inferiore del Sangiatto in the Italian Lepontine Alps during the Holocene. It reveals that both climate change and human activities have played significant roles in shaping the vegetation composition, with afforestation and species shifts occurring in response to climate warming and human impact leading to the formation of species-rich meadows and pastures. The findings suggest that under projected climate change and land abandonment, the treeline ecotone in the region is likely to shift and result in important changes in species composition and increased risk of biodiversity loss.

Summary: We present the first high-resolution Holocene pollen, plant-macrofossil, and charcoal records from the upper-montane zone in the central Dinaric Alps. Our study explores long-term ecosystem responses to variations in climate, fire disturbances and land use, as well as the legacy effects of past environmental changes. We found that different tree species in the region show varying sensitivities to summer temperatures, biomass burning, and human impact, indicating the complex interactions between climate, fire, and land use in shaping forest composition and dynamics.

Summary: The study revealed that over the past few thousand years, the coastal ecosystem and sea level in the northern part of northeastern Brazil have been influenced by various factors, including climate change and human activities. Analysis of vegetation and sediments showed that the environment in this region has undergone multiple changes, and human activity has intensified its impact on the area after the establishment of human settlements.

Summary: This study utilized multi-source satellite remote sensing image data to monitor and analyze wildfires in Sichuan Province. The research found that meteorological factors have the greatest impact on fire spread, and there is a correlation between vegetation coverage and fire severity. By combining multi-source remote sensing data, accurate and quantitative monitoring and analysis of wildfires can be achieved, providing important insights for fire prevention and control.

Summary: In this study, the relationship between fire and human development in the Kashmir Himalaya during the late Holocene was explored by measuring black carbon (BC) concentrations and its isotopic compositions (delta(13)(CBC)) in sediments from Wular Lake in India. The results showed that the region experienced two major climate phases, a dry phase and a wet phase. Forest fires in the Kashmir Himalaya were found to be mainly caused by human activities rather than large-scale climate change.

Summary: This study presents the first continuous pollen record for the Iberian Pyrenees during the Late Glacial-Early Holocene period. The aims of the study were to establish a chronostratigraphic correlation framework, understand the relationships between vegetation shifts, climatic changes, and fire, and obtain a regional picture of the vegetation during this period. The results revealed four vegetation types and showed wetter climates during the Younger Dryas, challenging previous assumptions of arid conditions. The study also found an increase in fire incidence during the Early Holocene. The findings were compared with other pollen records in the Pyrenean range and surrounding lowlands.

Summary: Tropical savannas and grasslands are frequently burned biomes, and fire plays an important role in sustaining ecosystem processes. Modern management of savanna fires incorporates traditional practices and earth observation data. This study proposes a remote sensing-based method for determining the end of the early dry season (EDS) burning window in order to prevent more destructive fires in the late dry season (LDS). The research finds that fuel connectivity is a strong driving factor for variability in EDS transition dates.

Summary: Rising temperatures and delayed summer rains have increased forest fire risk in South Africa's northern savanna biome. This study uses climate models to project future fire risk, showing widespread temperature rises and decreased rainfall. The results indicate that heat wave days and high fire danger days are projected to increase, particularly in the western savanna.

Summary: The study of a bauxite-bearing lateritic profile in the supergenic Fe-deposits of the Carajás Mineral Province in Brazil reveals its geological history dating back to the Paleocene-Eocene bauxitization event. The enrichment or depletion of Si, Al, Fe, and Ti elements in the lateritic horizons indicates complex chemical changes in the evolution of the profile.

Summary: Lanin volcano is a composite volcano in the Andes, which has erupted lava flows with different compositions. The volcano's magma reservoir contains a crystal mush, and the pre-eruptive conditions include temperature, pressure, and oxygen fugacity. Fractional crystallisation has led to the evolution of the magma with different compositions.

Summary: This study investigates the role of wedge integrity on the frequency content of strong ground motion produced by subduction earthquakes in Northern Chile. The results show that the frequency characteristics of seismic waves vary with hypocentral distance, indicating lateral variations in anelastic attenuation due to the heterogeneous tectonic structure.
