“…During March–May, the peninsular region also experiences wildfires in the deciduous forests and grassland, which eventually subside after the monsoon rains intensify. The frequency of forest fires or fires in grassland/shrublands in both areas has significantly increased over the past few decades, which is considered an adverse impact of anthropogenic global climate warming (Chakraborty et al., 2018; Kumar et al., 2022; Ravindranath & Sukumar, 1998). In the lowland YSB, biomass‐burning activities such as stubble burning over approximately 5,504–1,268 km 2 area are recorded annually from the agricultural lands and the grassland/shrublands just before the monsoon downpours.…”

Natural or anthropogenic‐induced biomass burning produces large amounts of charcoals, which enter riverine or lacustrine systems mostly via surface runoff processes. Charcoal storage and cycling within large riverine systems can play a crucial role in mediating long‐term carbon sink across transient reservoirs, thereby influencing the global carbon budget. However, natural processes governing the transport and storage of charcoal particles in large terrestrial reservoirs such as the Indo‐Gangetic region still remain unknown. To understand charcoal movement and accumulation across upland and lowland transient reservoirs, we characterized spatial distribution and morphology of different charcoal forms (>125μm and <125μm) from bedload and floodplain sediments of the Yamuna sub‐basin (YSB), India. Both >125μm and <125μm charcoal forms in bedload and floodplain sediments did not exhibit similar spatial distribution patterns, indicating segregation of charcoal particles influenced by variable flow regimes. Attrition with sediments breaks down fragile charcoals (leaves) quickly compared to the woody forms, resulting in dominant woody microforms in transient deposits. Higher stream power and limited stable bedform development in upland mountainous regions restrict charcoal storage. During lowland riverine transits, reduced stream power conditions allow increased floodwater inundation and finer clay substrate availability, facilitating an exponential increase in charcoal storage. However, increased discharge from peninsular rivers into the YSB lead to erosion and redistribution of sediment, including charcoal particles, and reduced charcoal storage in lowland transient areas. Such diverse dispersal pathways and fate of charcoal particles across riverine transits highlight the influence of regional hydrogeomorphic processes on the overall carbon cycle within transient reservoirs.

Similipal Biosphere Reserve is indeed an important natural treasure and holds significance for several reasons as the 7th largest biosphere reserve in India. India’s Mayurbhanj is one among the World’s Greatest Places of 2023 along with the Similipal Biosphere, the Time magazine has included it is the only place in the world where black melanistic tigers were spotted that’s why the researchers all across the globe are curious to explore Mayurbhanj and its rich biodiversity. The Similipal comprises 7% flowering plants, 8% Orchids, 7% Reptiles, 20% birds and 11% mammals. A significant natural resource, forests are crucial to preserving the ecological equilibrium. Forests are now endangered by both man-made and natural forest fires as a result of growing population and civilisation. Basically, there are three different categories into which forest fire causes may be divided: Natural, Intentional/Deliberate, Accidental, and Unintentional are the four categories. In India, human anthropogenic activities that involve slash-and-burn agriculture, deforestation, controlled burning, firewood burning, etc. are to blame for almost 90% of forest fires. Therefore, in nations like India, it is crucial to monitor and manage forest fires. Anthropogenic impact can easily be detected with the satellite data such as Landsat-5, Landsat-8 & MODIS are collected and processed in Arc GIS 10.8 & Google Earth Engine.

“…Studies investigating the impact of forest fire frequency on vegetation in Central India have yielded varied conclusions. On one hand, researchers found that forest fire hotspots in central India exhibited comparatively lower tree density and dominance, indicating a negative effect on vegetation recovery [33]. Conversely, researchers reported non-linear trends in tree diversity in response to fire frequency, with fluctuations observed across different fire severity classes [34].…”

Forest fires can cause calamitous damage to the forest ecosystems and may affect climatic parameters, such as temperature, evapotranspiration, and precipitation by catalyzing changes in the local ecology of the region. The main research objective of this work was to quantify the different indices as well as to identify the changes in years 2011 and 2020 in pre- and post-fire, these parameters, such as Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST) and Normalized Burn Ratio Index (NBR), associated with the severity of forest fires in the Damoh district of Madhya Pradesh. An attempt has been also made to understand the interrelationship of these parameters to gauge how these may correlate to determine the sensitivity to forest fires. In this context, we have incorporated advanced GIS methods for the identification of the pre-post fires for 2011 and 2020 year from Landsat 5 and Landsat 8 OLI/TIRS level -1 and Random Forest (RF) model in the Google Earth Engine (GEE) platform. Land Use Land Cover (LULC) map was categorized into five classes based on the satellite data sets. Our findings indicate elevated Land Surface Temperature (LST) values in the Northern and Central regions of the study area, reaching 32.0°C before the fire event. Subsequently, following the fire incident in the year 2011, LST escalated to 39.0°C. Similarly, in the southern and south-eastern regions of the Damoh district, LST peaked at approximately 43.0°C coinciding with the onset of a forest fire in 2020. Furthermore, our analysis revealed a negative correlation between the Normalized Difference Vegetation Index (NDVI) and LST, whereas the Normalized Burn Ratio (NBR) displayed a positive correlation with LST. These results underscore the impact of LST on forest vegetation dynamics, with LST nearing 39.0°C indicating an increased risk of forest fires. The results of this study can be used by local administration to devise an efficient policy related to forest fire management.
