“…The larger the gas emissions in the region, the more severe the forest fire. This could be attributed to the greater heat released by the fire, the higher the rate of gas production [49] and the shorter the time to reach the carbon satellite sensor.…”

Greenhouse gases such as CH4 generated by forest fires have a significant impact on atmospheric methane concentrations and terrestrial vegetation methane budgets. Verification in conjunction with “top-down” satellite remote sensing observation has become a vital way to verify biomass-burning emission inventories and accurately assess greenhouse gases while looking into the limitations in reliability and quantification of existing “bottom-up” biomass-burning emission inventories. Therefore, we considered boreal forest fire regions as an example while combining five biomass-burning emission inventories and CH4 indicators of atmospheric concentration satellite observation data. By introducing numerical comparison, correlation analysis and trend consistency analysis methods, we explained the lag effect between emissions and atmospheric concentration changes and evaluated a more reliable emission inventory using time series similarity measurement methods. The results indicated that total methane emissions from five biomass-burning emission inventories differed by a factor of 2.9 in our study area, ranging from 2.02 to 5.84 Tg for methane. The time trends of the five inventories showed good consistency, with the Quick Fire Emissions Dataset version 2.5 (QFED2.5) having a higher correlation coefficient (above 0.8) with the other four datasets. By comparing the consistency between the inventories and satellite data, a lagging effect was found to be present between the changes in atmospheric concentration and gas emissions caused by forest fires on a seasonal scale. After eliminating lagging effects and combining time series similarity measures, the QFED2.5 (Euclidean distance = 0.14) was found to have the highest similarity to satellite data. In contrast, Global Fire Emissions Database version 4.1 with small fires (GFED4.1s) and Global Fire Assimilation System version 1.2 (GFAS1.2) had larger Euclidean distances of 0.52 and 0.4, respectively, which meant that they had lower similarity to satellite data. Therefore, QFED2.5 was found to be more reliable while having higher application accuracy compared to the other four datasets in our study area. This study further provided a better understanding of the key role of forest fire emissions in atmospheric CH4 concentrations and offered reference for selecting appropriate biomass burning emission inventory datasets for bottom-up inventory estimation studies.

“…Upon burning, a vast amount of carbon is released into the atmosphere (Gibbs et al 2007). Increasingly, forest fire is recognised as a prime concern of greenhouse gas (GHG) emissions and particulate matters in the HKH as well as other regions (Martinho 2019). A recent study of the amazon forest shows that there is a significant emission of carbon dioxide mainly due to intentional forest fires aimed at clearing the land for beef and soy production (Carrington 2021).…”

Forest fire has been one of the compelling issues in the Hindu Kush Himalayan (HKH) region. To promote regeneration, clearing fields for agriculture, hunting, and security reasons, local people deliberately set forests on fire. In this paper, active fire incidents, temperature, precipitation, and the changes of Aerosol Optical Depth (AOD) and Carbon monoxide (CO) value associated with forest fire were evaluated. The active forest fire incidents obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite are supplemented by the ERA5-land dataset to see the relation between precipitation and temperature with forest fires. MODIS and Tropospheric Monitoring Instrument (TROPOMI) sensor datasets were used to see the changes in AOD and CO in the region. MODIS sensor detected more than 30,462 active fires incidents in March and April 2021 in the study areas. Shan State of Myanmar recorded the maximum number of active fire incidents which is due to the practice of shifting cultivation and minimum in Bhutan due to the awareness campaigns and technology improvement. The temperature recorded in the study sites shows an increasing trend as compared to the reference period (2010-2020). Apart from Shan and Bago of Myanmar, precipitation in the study sites is also less during the study period. AOD and CO values show prominent peaks in a fire season which coincide with days of the maximum number of fire counts inferring the influence of forest fire on air quality. Developing countries like Nepal, India, Myanmar, and Bhutan are willing to take part in climate finance and are bound to accept expensive insurance premium due to forest fire incidents. Unless forest fires are effectively managed and mitigated, achieving Nationally Determined Contributions (NDCs) and global agendas, including United Nations Decade of Ecosystem Restoration is onerous.

“…These questions are of the utmost important for Mediterranean countries dealing with forest fire problems. Forest fires have several consequences on socioeconomic and environmental domains for regions impacted by these abiotic forests disturbance agents [3], compromising the forest contributions for climate change mitigation [4]. This is a major problem due to forest contributions on climate change mitigation [5].…”

Forest land provides several environmental services and goods with significant implications for different socioeconomic and environmental dimensions. Forestry and its management are determinant activities for sustainable development, specifically in the current context of urgent mitigation of climate change. In this perspective, one objective of this research was to survey the main insights from the literature about the forest and management dimensions put together, highlighting the contributions of these activities to mitigate climate change. Another objective was to explore indicators related to forest management (land, employment, output, and net emissions) in order to obtain a forest sustainability index through factor analysis. As main insights from this study, we can quote that the literature survey pinpoints the most relevant factors framing forest management: soil characteristics, ecology, ecosystems, biodiversity, deforestation, climate change, socioeconomic frameworks, local knowledge, public policies, institutional context, and new technologies. Forest indicators reveal a strong relationship between forest land, employment and output, and a weaker relation with net emissions. We concluded that there is a need for stakeholders to explore and improve the interlinkage with climate change impact, specifically with regard to improving the relationships of forestry greenhouse gas emissions impacts with forest size and output.
