In India 90 percent forest fires are estimated to be man made. About 3.73million hectare forest area is affected by fires leading to a loss of Rs 440 crores annually. A fire risk model has been developed for Dholkhand Range of Rajaji National Park (India) by combining the weather data, fuel conditions and human activity within the area of study. The study integrates remote sensing data of IRS LISS III for generation of fuel map with GIS for generation of topographical gradients. The model requires as inputs as Normalized Difference Vegetation Index (NDVI) values for calculating the Relative Greenness, meteorological data for estimating the Dead Fuels Moisture Content, and a Fuel Map to estimate the fuel loads. Combining historic climate data with size, intensity, extent, and other characteristics of historic fires allows an assessment of the relationship between climate and fire. For this the Weather data for the last five years has been used along with fuel moisture to assess the relationship between moisture and the fire season. Human factor is important to consider for fire risk modeling and the values assigned to it are subjective in nature. Fire start locations have been correlated with these human parameters, such as the relationship between road buffers, human settlements and fires caused by humans in a particular area. The study shows that anthropogenic factors coupled with fire favourable microclimate contributes more to fire occurrence than natural climate also. The fire risk model so generated will be validated for the last five years including current fire year (2005). The model will help in developing appropriate forest fire control and management plan.
