The World Health Organization estimates that 100 thousand people in the world die every year from asbestos-related cancers and more than 300 thousand European citizens are expected to die from asbestos-related mesothelioma by 2030. Both the European and the Italian legislations have banned the manufacture, importation, processing and distribution in commerce of asbestos-containing products and have recommended action plans for the safe removal of asbestos from public and private buildings. This paper describes the quantitative mapping of asbestos-cement covers over a large mountainous region of Italian Western Alps using the Multispectral Infrared and Visible Imaging Spectrometer sensor. A very large data set made up of 61 airborne transect strips covering 3263 km2 were processed to support the identification of buildings with asbestos-cement roofing, promoted by the Valle d'Aosta Autonomous Region with the support of the Regional Environmental Protection Agency. Results showed an overall mapping accuracy of 80%, in terms of asbestos-cement surface detected. The influence of topography on the classification's accuracy suggested that even in high relief landscapes, the spatial resolution of data is the major source of errors and the smaller asbestos-cement covers were not detected or misclassified.

Summary (excerpts from the chapter) Wildfire risk assessment is fundamental for developing prevention, mitigation and preparedness plans. Many countries have customized approaches to assess wildfire risk and these vary widely among them [.]. The level of elaboration of these assessments is often related to the impact of fires in these regions and countries. Normally, those countries more often confronted with wildfires are more prepared and have elaborated detailed wildfire risk maps at country/regional level. However, this process has led to different regional/national approaches that are not comparable, although wildfires are often ...
