Carbon fluxes are valuable indicators of soil and ecosystem health, particularly in the context climate change, where reducing carbon emissions from anthropogenic activities, such as forest fires, is a global priority. This study aimed to evaluate impact prescribed burns on respiration semi-arid grasslands. Two treatments were applied: burn 12.29 ha paddock an introduced grass (Eragostis curvula) with 11.6 t ha−1 available fuel, simulation three fire intensities, over 28 circular plots (80 cm diameter) natural grasslands (Bouteloua gracilis). Fire intensities simulated by burning butane gas inside iron barrel, which represented amounts fuel biomass unburned treatment. Soil was measured chamber two months, readings collected morning afternoon. Moreover, CO2 combustion productivity after treatment quantified. The significantly reduced respiration: all resulted decrease when compared area. Changes albedo increased temperature; however, there no relationship between changes temperature respiration; contrast, precipitation highly stimulated it. These findings suggest that fire, under certain conditions, may not lead more being emitted into atmosphere stimulating respiration, whereas aboveground 60%. However, considering effects long-term nutrient deposition, belowground biomass, properties crucial effectively quantify its cycle.

Extreme forest fires have historically been a significant concern in Canada, the Russian Federation, USA, and now pose an increasing threat boreal Europe. This paper deals with application of wildFire cLimate impacts Adaptation Model (FLAM) forests. FLAM operates on daily time step utilizes mechanistic algorithms to quantify impact climate, human activities, fuel availability wildfire probabilities, frequencies, burned areas. In our paper, we calibrate model using historical remote sensing data explore future projections areas under different climate change scenarios. The study consists following steps: (i) analysis over 2001–2020; (ii) temperature precipitation changes as compared period; (iii) projected by driven scenarios until year 2100; (iv) simulation adaptation options worst-case scenario. modeling results show increase all Representative Concentration Pathway (RCP) Maintaining current temperatures (RCP 2.6) will still result area (total forest), but scenario 8.5), more than triple 2100. Based calibration, identify hotspots for wildland suggest such suppression efficiency at hotspots.

The soil aggregate is the fundamental unit of structure. fractionation characteristics and influencing factors phosphorus (P) in aggregates inherently link its geochemical recycling mechanism. This work investigated inorganic P cold temperate forest soils studied impacts recovery periods after fires protection mechanisms on fractionation.

The extreme Black Summer Bushfires in 2019–2020 originated the Blue Mountains near Sydney and spread throughout several rural regions within New South Wales, increasing country's vulnerability to severe fire incidents. In response, initiatives were launched create disseminate retrofit guides mitigate risks associated with property protection. These efforts financially supported by government agencies resulted development of various methodologies national programmes adhering building standards. However, predominant extent damage residential structures was observed dwellings built prior 1990s, before improved codes for bushfire resilience introduced. Further, 34% Australians over 65 live remote areas, a higher risk exposure. Elderly face multiple challenges, such as health status mobility limitations, communication barriers, access resources that impede their capacity engage home retrofitting maintenance activities, especially absence centralised resource guide improvement resilience. case study methodology employed this research, explicitly emphasising two geographic areas: Bega Valley Shire Wales Noosa Queensland. data collection included focus groups, site visits, interviews, which helped develop tailored assessment toolkit. methods utilised investigate dimensions, including personal heritage considerations, accessible design principles, construction, landscape. findings form foundation informed decision-making proactive measures safeguard vulnerable individuals fire-prone areas.

Studies on the effects of wildfires soil are common in mixed-conifer forests worldwide; however, such studies less frequent context high-altitude forests. In this research, we analyzed physicochemical properties 14 years after a high-intensity wildfire. Soil samples were collected from depth 0–10 cm across 100 composite samples, representing both control and burnt areas. Our findings revealed significant changes characteristics area compared to area. Specifically, average pH, electrical conductivity, available potassium increased by 3 %, 81 53 respectively, area, while phosphorus decreased 6 %. Conversely, total nitrogen organic matter showed non-significant decreases 20 % 12 No differences found slope aspects. Electrical conductivity varied significantly among upper (3300–3500 m), middle (3100–3300 lower (2900–3100 m) altitude ranges. Principal component analysis explained 50.1 variance, with approximately 27.4 first axis 22.7 second axis.
