Book Description
By monitoring the greenness of vegetation, it may be possible to provide fire management agencies with timely information on changing forest hazard conditions. This study monitors general seasonal variation in greenness throughout the 1993 growing season in Ontario using 1-kilometre resolution Advanced Very High Resolution Radiometer ten-day composites. Data for several sample sites across Ontario's major forest regions are analyzed to report on the seasonal trends. A second aspect of the study monitors annual variation in greenness by studying four phenologically coincident scenes of the Sudbury Basin, with images taken over two decades using 50-metre-resolution LANDSAT data and analyzed to show increases in vegetation due to reductions in sulphur dioxide emissions. A simple regression equation that depends on a fuel moisture parameter was used to model and predict forest fire occurrence in the Basin area and indicate the effect of revegetation on forest fire decreases.

Book Description
Wildland fires are becoming one of the most critical environmental factors affecting a wide range of ecosystems worldwide. In Mediterranean ecosystems (including also South-Africa, California, parts of Chile and Australia), wildland fires are recurrent phenomena every summer, following the seasonal drought. As a result of changes in traditional land use practices, and the impact of recent climate warming, fires have more negative impacts in the last years, threatening lives, socio-economic and ecological values. The book describes the ecological context of fires in the Mediterranean ecosystems, and provides methods to observe fire danger conditions and fire impacts using Earth Observation and Geographic Information System technologies.
