In this work, we present, with some clarity, a methodology for studying fire behavior in wildfires and vegetation fires, useful and adaptable to the tropical context, in general, and Angola, in particular. We begin by contextualizing the theme on the basis of the classic and modern bibliography consulted, we describe the physiographic characteristics of the target area of this study, as well as the methodology adopted and tested in the case study that constitutes the results presented in this emblematic book.
