Humans have been changing the natural fire regimes in most Brazilian vegetation types for over 4000 years. Natural lightning fires can easily happen in savannas and grasslands, but they are rare in the moist rainforests. Today, anthropogenic fires are frequent in both the fire-adapted cerrado (…
The vegetation in the southern Brazilian highlands is characterized by Araucaria forest and Campos grassland. Evidences indicate that Araucaria forest is currently expanding over grassland and that this expansion may occur by nucleation or edge dynamics. Nucleation mechanisms of Araucaria forest…
This research aims to improve land-cover classification accuracy in a moist tropical region in Brazil by examining the use of different remote-sensing-derived variables and classification algorithms. Different scenarios based on Landsat Thematic Mapper (TM) spectral data and derived vegetation…
As the biofuels are emerging as promising alternative transportation fuels across the world, they also offer huge potential for international trade in biofuels. A number of trade barriers such as import tariffs and domestic support have limited the scope for trade in biofuels. The purpose of…
