Forest Fire Risk Zonation Using Geospatial Techniques and Analytic Hierarchy Process in Dehradun District, Uttarakhand, India
Journal Title: Universal Journal of Environmental Research and Technology - Year 2014, Vol 4, Issue 2
Abstract
Forest fires are one of the major natural risks in the forest of Uttarakhand. In such areas, fire occurs frequently and there is a need for global approaches that analyze wide scenarios of factors involved. It is impossible to control nature, but is possible to map forest fire risk zone (FFRZ) and thereby minimize the frequency of fire. The aims of the present study are 1) to set up and analyse the FFRZ over forested region of Dehradun 2) to see whether these forest fires are natural in nature or deliberately caused by people living adjacent to forest 3) to find firs prone areas and their prioritization. The model deals to combine geospatial data by Geographic Information System (GIS) technology to construct the FFRZ map. Influencing factors like vegetation moisture, slope, aspect, elevation, distance from roads, and vicinity of settlements have been taken into consideration. These variables were weighted based on their impact on the fire risk. Around 3.13% of total forested area was found to be in very high risk zone and 50.25% area was found to be in high-risk zone. The distribution of fire data over the FFRZ map shows that a very small part of them (1.26%) falls under very high risk zone and majority (98.74%) comes under high and moderate high risk zone areas. It indicates to a great extent that major part of forest fire is natural in nature and non-intentional. The people living nearby have the least role in causing these forest fires.
