Résumé
Forest fires are a major factor of environmental transformation in several ecosystems. Fires have global impacts, affecting forested areas and having an important impact in greenhouse gas emissions. Additionally, fires have local impacts, associated to soil degradation, soil erosion, vegetation dynamics, and lost of lives and properties. Fire prevention is critical to reduce the negative impacts of fire. This paper presents the input variables and the integration scheme developed within the Firemap project (funded under the Spanish Ministry of Science and Technology) to map wildland fire occurrence probability. The project first generated fire risk variables related to several factors of fire ignition or propagation. They were generated from a wide variety of sources using geographic information systems and remote sensing technologies. All variables were mapped at 1 sq km spatial resolution, and were integrated into single indices. The risk system included the development of a dedicated web-mapping server to facilitate the access to the end-users. This service was tested in the summer of 2007 for semi-operational use. The paper presents the first validation results of the danger index, by comparing temporal trends of the different danger components to the fire occurrence in the Madrid region, one of the test sites.
