Fire risk map for the Canguiri Experimental Farm, Pinhais (PR).

Abstract

The objective of this research was the elaboration of a fire risk map for the Canguiri Experimental Farm, located in Pinhais county, State of Parana, Brazil, owned by the Federal University of Parana. With the support of geoprocessing tools, individual maps for declivity, aspect, altimetry, roads, hydrography and land use were produced. These variables, with the same degree of importance, were integrated by addition. The individual maps overlapping generated the fire risk map, that presented the following results: low risk for 12.7% of the area, moderate risk for 52%, high risk for 29.9%, and very high risk for 5.8%; no extreme risk was detected in the area. These percentages were considered acceptable, since land occupation in the experimental farm perimeter is mainly agriculture and pasture, where fire has been used as a managing tool.
