A study conducted by scientists from Brazil, the United States and Portugal investigated the accuracy and consistency of different satellite data collections with regard to the location and size of burned areas in the Cerrado biome, the Brazilian savanna.
Results - International - Journal - Applied - Earth
The results, published in the International Journal of Applied Earth Observation and Geoinformation will help improve the output produced by Programa Queimadas, a program run by Brazil's National Space Research Institute (INPE) to monitor wildfires and burns by satellite and to calculate and forecast forest fire risk.
The study was linked to the Brazilian Fire-Land-Atmosphere System (BrFLAS), a project supported by São Paulo Research Foundation—FAPESP. Its principal investigator was Renata Libonati, a professor at the Federal University of Rio de Janeiro (UFRJ) in Brazil, in collaboration with researchers at the University of Maryland (USA) and the University of Lisbon (Portugal). The study was also one of several projects conducted as follow ups to the master's research of the first author Júlia Abrantes Rodrigues.
Studies - Fire—which - Part - Strategy - Area
Several previous studies showed that fire—which can be used intelligently as part of a properly considered strategy with total area zoning and a rotating fire schedule—is indispensable to renewal the Cerrado.
The indiscriminate, often criminal, use of fire to eliminate native plants and prepare land for crops and extensive cattle grazing is a different story. "In this case, areas are burned repeatedly at very short intervals, almost always in the dry season, and no vegetation can survive. Natural adaptation is impossible," says environmental engineer Alberto Setzer. Setzer is a researcher at INPE and a coauthor of the article.
Aspect - Emissions - Year
"A most important aspect to consider is the atmospheric emissions from burning. Depending on the year, they can account...
