Dissertação (Mestrado em Geografia) - Universidade Federal de Goiás, Goiânia, 2010.http://repositorio.bc.ufg.br/tede/handle/tede/3185The Cerrado biome has many favorable characteristic, like soil, relief, and dense hydrography, for the development of mainly economic activity, as agriculture and pasture, this biome has suffered high human disturbance process. Along with human activities, the practice of burning was increased, particularly for the practice of grazing management, pest control, cleaning of areas for agricultural planting and others. The fires have several consequences for the biome, amongst them have increasing of temperature, decreasing rainfall, genetic impoverishment of natural species, increases the risk of respiratory diseases. In this research, for mapping burned areas in the Cerrado biome between 2002 to 2008 was used MCD45A1 MODIS product, which makes the mapping of burn scars globally scale. The result is that fires occur during the year in the Cerrado, reaching its peak between July to September, warm and dry period with the lowest relative humidity. The burned areas are located in larger amounts in the north-central part of the Cerrado, mainly in the expansion of agriculture in the states of Bahia, Piaui, Maranhao, Mato Grosso and Tocantins. However, the fires, based on mapping of the PROBIO Cerrado, occur in greater proportions in regions of natural vegetation cover (81.7%), and among vegetation types most affected are the wooded savanna (34.1%) and savanna parkland (29.7%). As for the river watershed, such as Amazon, San Francisco, Parnaíba, Paraná, and especially Tocantins-Araguaia (46.4% of fires between 2002 and 2008 were concentrated in the watershed) were the hardest hit by the effects of fire during the burning of biomass (combustible material). The fires hit large of Protected Areas (PAs) located in the biome, such as the sustainable use and integral protected areas, where the Environmental Protection Areas (APA) and National Parks (NP) were most affected. In relation to priority areas for conservation of biodiversity in the Cerrado biome the areas with extremely high priority received the greatest records of fires within its limits, as indigenous lands, protected areas, and was severely affected by fires in relation to others in the same period. As for the validation of the data MCD45A1 MODIS product, burned area from LANDSAT TM, satellite images, were quite satisfactory for the Cerrado, because of the area burned 11,126 polygons (MCD45A1) visually inspected, all were labeled as burntapplication/pdfAcesso AbertoMCD45A1MODISQueimadasCerradoBurnedCIENCIAS HUMANAS::GEOGRAFIADissertação
