Using VGT images from south-eastern Africa, the Iberian Peninsula and south-eastern Siberia/north-eastern China, we analysed the variability of the spectral signature of burned areas and its relationship with land cover, and performed the selection of the best variables for burned area mapping. The results show that in grasslands and croplands, near-infrared (NIR) and short-wave infrared (SWIR) reflectance always decreases as a result of fire. In forests and woodlands, there may occur a simultaneous decrease of SWIR and NIR or an increase of SWIR and a decrease of NIR. Burning of green vegetation (high values of the Normalized Difference Vegetation Index (NDVI)) tends to result in an increase of the SWIR. The best variables for burned area mapping are different in each region. Only the NIR allows a good discrimination of burned areas in all study areas. We derived a logistic regression model for multi-temporal burned area mapping in tropical, temperate and boreal regions, which handles the spectral variability of burned areas dependent on the type of vegetation. The results underline the feasibility of a single model for global burned area mapping.

[Termes IGN] volcanRésumé : (Auteur) An innovative, Advanced Very High Resolution Radiometer (AVHRR)-based technique for improved automatic detection of volcanic Hotspots and thermal anomalies is proposed in this paper. It is mainly based on a multitemporal analysis of historical, long-term satellite records. Such a technique basically rests on the Robust AVHRR Techniques (RAT) approach, which has been already successfully applied to sevreral natural and environmental emergencies (e.g., fires, floods, earthquakes). In this work, the proposed technique has been tested on an extended set of eruptive events of Mt. Etna and Stromboli volcanoes. Results achieved, in terms of reliability (low false alarm rate) as well as of effectiveness (detection sensitivity), are described in detail. Moreover, the potential in low-level thermal anomaly detection, as possible pre-eruptive thermal signs, is also addressed and preliminary results obtained for a couple of events, discussed. The study cases here presented show the benefits of such a technique especially when different observational conditions (time/season of pass, atmospheric moisture content, solar illumination, satellite angles of view, etc.) are considered, making such a method globally applicable. The future prospects, also in terms of possible operational scenarios, coming from the implementation of such an approach on the new generation of satellite sensors (such as SEVIRI aboard Meteosat Second Generation) are also discussed.

[Termes IGN] spectre électromagnétiqueRésumé : (Auteur) A massive forest fire in Indonesia in 1997 affected the whole Asian region by producing a large smoke plume, with Malaysia bearing the brunt due to the wind direction and weather conditions and because of its proximity to the source. The five primary fire produced pollutants were carbon monoxide (C0), sulphur dioxide (S02), nitrogen dioxide (N02), ozone (03) and particulate matter less than 10 um (PM10). The first four of these are, of course, invisible to conventional satellite-flown multispectral scanners operating in the visible and near infrared regions of the electromagnetic spectrum. The fifth PM10, is present in the haze and therefore makes an observable contribution to the signal received by the Advanced Very High Resolution Radiometer (AVHRR). The haze in AVHIRR channels 1 and 2 data for the fires of September 1997 has been used to study the concentration of PM10 directly. It has also been used to study the concentration indirectly-as a tracer or surrogate-for the four remaining materials, the gases CO, S02, N02 and 03). Data from ground observations have been used to calibrate the results and the distributions of the fire pollutants over Peninsular Malaysia have been plotted.

[Termes IGN] risque majeurRésumé : (Auteur) Society is rapidly becoming more vulnerable to natural disaster as populations become increasingly concentrated in expanding urban conglomerates. In addition, we face threats from changes in the global environment, including the possibility of severe typhoons, rising sea levels and drought. Such changes in ambient conditions have made society more vulnerable. There is environmental degradation and a lack of planning, land management and preparedness. The author presents strategies for prevention and highlights the importance of availability of spatial information for early warning, risk assessment and risk management, prevention and reconstruction.

[Termes IGN] lutte contre l'incendieRésumé : Le feu comme outil de prévention pour limiter le risque d’incendie de forêt. Cette idée, quelque peu dérangeante à l’origine, a fait son chemin au cours des dernières décennies pour s’imposer aujourd’hui tant au niveau de la pratique, de son assise institutionnelle que de la connaissance des effets induits sur le milieu. Outil polyvalent et technique en pleine expansion, le brûlage dirigé est également de plus en plus utilisé dans des applications environnementales.
