Assessment of increasing threat of forest fires in Rajasthan, India using multi-temporal remote sensing data (2005-2010)

Rajasthan is the largest state of India experiencing recurrent forest fires. The present study determines forest burnt areas through remote sensing-based time series analysis. IRS P6 AWiFS satellite data covering March, April and May of six years (2005–2010) were used to cover all forest-fire events. The total forest burnt area was assessed as 53,023.5 ha in 2005; 44,681.5 ha in 2006; 57,689 ha in 2007; 89,655.2 ha in 2008; 199,837 ha in 2009 and 144,816 ha in 2010. Forest fires were observed only in the southern Aravallis.
