FOREST FIRES FROM SPACE: CONSIDERING SPATIAL AND TEMPORAL RESOLUTION Dr. Emilio Chuvieco and David Cocero Department of Geography University of Alcalä de Henares Colegios, 2 - 28801 Alcalä de Henares (Spain) KEY WORDS: Forest Fires, Resolution, Estimation, Change-detection ABSTRACT: Forest fires are a major environmental concern in Tropical and Mediterranean countries, since it is the main responsible of vegetation degradation. Satellite remote sensing data could play a crucial role in improving current tools of fire prevention and fire effects assessment, since they provide a suitable image of spatial and temporal variation to monitor fire-related factors. Real-time monitoring of vegetation water stress or burned land mapping are examples of products closely connected to fire management planning. This paper explores present applications and future requirements of remote sensing systems for forest fire studies, with special emphasis in the needs of European Mediterranean countries. 1. INTRODUCTION Wildland fires are becoming a major concern for several Environmental Sciences. Assessment on fire effects at local scale is increasingly considered a critical aspect of ecosystem functioning, since fire plays a crucial role in vegetation composition, biodiversity, soil erosion and the hydrological cycle. At global scale, fire is the most generalised mean to transform tropical forest in agricultural areas, and it has severe impacts on global atmospheric chemistry (Crutzen et al., 1979). Fire is a natural factor in many climates, such as the Mediterranean, with high levels of vegetation stress during the summer. However, changes in traditional land use patterns have recently modified the incidence of fire in these territories. Rural abandonment in the European Mediterranean basin has implied an unusual accumulation of forest fuels which notably increases fire risk and fire severity. On the other hand, the increasing use of forest as a recreational resource involves a higher incidence of human induced fires, either by 45 carelessness or arson. According to recent fire statistics more than 200,000 fires have affected the Mediterranean countries of Europe between 1990 and 1993. Around 2,000,000 hectares have been burned in these years, although the extension will significantly increase if fires of 1994 were computed, as they burned, only in Spain, more than 400,000 hectares. The damages caused by forest fires are very difficult to estimate, because they have diverse and indirect effects on several environmental processes. Remote sensing from space is specially suitable for forest fire research. The wide area coverage and repetitively provided by satellite sensors, as well as their information on non visible spectral regions, makes them a very valuable tool for prevention, detection and mapping of wildland fires. During the last decade, the range of applications has significantly ^ increased (Chuvieco and Martin, 1994a), making satellite remote sensing a solid ally in many forest fire strategic plans. Remote Sensing contributions may be classified in four type of applications, related to the temporal scale being underlined: short-term fire danger estimation, long-term International Archives of Photogrammetry and Remote Sensing.
