The increased frequency and intensity of forest fires brought on by anthropogenic activity and climate change have made them a serious ecological concern. This study employs geospatial tools to examine the zonation of forest fire risk in relation to environmental and vegetation health indices. In order to create a Forest Fire Risk Zonation (FFRZ) map, a number of characteristics were examined, including slope, aspect, Land Surface Temperature (LST), Normalised Difference Vegetation Index (NDVI), and proximity to anthropogenic causes.

摘要

The increased frequency and intensity of forest fires brought on by anthropogenic activity and climate change have made them a serious ecological concern. This study employs geospatial tools to examine the zonation of forest fire risk in relation to environmental and vegetation health indices. In order to create a Forest Fire Risk Zonation (FFRZ) map, a number of characteristics were examined, including slope, aspect, Land Surface Temperature (LST), Normalised Difference Vegetation Index (NDVI), and proximity to anthropogenic causes. LST and NDVI were used simultaneously to calculate an Environmental Criticality Index (ECI), which was used to determine environmentally sensitive areas. By comparing the Delta Normalised Burn Ratio (dNBR) and Delta Chlorophyll Index (dCI), the study investigated post-fire effects in greater detail. The results showed a significant negative connection, which is suggestive of the decline in plant health brought on by fire events. ECI and FFRZ showed an apparent positive connection, indicating that environmental stresses have an impact on fire risk. The findings highlight the value of remote sensing indices for environmental monitoring and integrated fire risk assessment in order to guide forest management plans.
