Descrição
The scientific community interested in atmospheric chemistry, gas emissions from
vegetation fires, and carbon cycling is currently demanding information on the extent and timing of biomass burning at the global scale. In fact, the area and type of vegetation that is burned on a monthly or annual basis are two of the parameters that provide the
greatest uncertainty in the calculation of gas and aerosol emissions and burned biomass.
To address this need, an inventory of burned areas at monthly time periods for the year
2000 at a resolution of 1 km2 has been produced using satellite data and has been made freely available to the scientific community. In this paper, estimates of burned area and number of burn scars for four broad vegetation classes and reported at the country level for the year 2000 are presented using data taken from the inventory. Over 3.5 million km2 of
burned areas were detected in the year 2000, of which approximately 80% occurred in
areas described as woodlands and shrublands. Approximately 17% of the burned area
occurred in grasslands and croplands, the remaining 3% occurred in forests. Almost
600,000 separate burn scars were detected. Descriptions of vegetation burning activity are given for ten regions. Finally, monthly burned area estimates are presented for the Central African Republic to illustrate the usefulness of these data for understanding, monitoring and managing vegetation burning activities.
