1 Forest fire hazard mitigation in Lebanon using remote sensing and GIS Ghaleb Faour, CNRS Lebanon نحو آلية مستدامة لمكافحة حرائق الغابات في لبنان

2 Objective The specific objective of this project was to implement Geographic Forest Fire Information System including the database collection and analysis, development of a fire risk map at the National level and at municipality level for the five pilot areas namely Ramlieh, Kornayel, Ras El Matn, Dmit and Mtein.

7 Causes of forest fire occurrence Natural conditions Anthropic conditions

8 Forest fire hazard mitigation in Lebanon using remote sensing and GIS Identification of burnt areas

9 Forest fire hazard mitigation in Lebanon using remote sensing and GIS Fire Risk Map

10 Forest fire hazard mitigation in Lebanon using remote sensing and GIS Forest Fire Risk Map Fire occurrence map

11 Forest fire hazard mitigation in Lebanon using remote sensing and GIS National Forest Fire Risk Map

12 Same methodology local parameters Higher precision: - Slope/Aspect: from contours lines 10m - Landuse: updated at 1/ Evapo-transpiration/nb of fires: the same - NDVI: from SPOT image (10m resolution) Fire Risk Map at Municipality level

13 Data collection

15 Forest fire hazard mitigation in Lebanon using remote sensing and GIS Fire Risk Map at municipality level

16 Conclusion The obtained forest fire risk maps can be used in assigning in tactical decisions on prioritizing fires for initial attack. They give an indication of forest fires at long-term and they will be utilized by policy-makers to protect area suffering from fires. More work is required to better quantify values and risks, as well as suppression capability. The incorporation of a spatial climate model would improve fire behavior predictions.
