Description :
The aim of this study is to characterize spatio-temporal characteristics of fire events in Orissa state, eastern India. In this study, ATSR satellite remote sensing data have been used to quantify fire events from 1997 to 2006. The spatial scan statistic that quantifies hotspot areas of fire risk has been used to identify statistically significant fire clusters during the ten-year time period. To assess the causative factors of fires, topographic, vegetation, climatic, anthropogenic and accessibility factors were used in a multivariate statistical framework. Results suggested a clear variation in hotspots of fire occurences among districts.
