Mapeamento semidetalhado do uso da terra do Bioma Cerrado

EDSON EYJI SANO, Roberto Rosà, Jorge Luis Silva Brito … (2008)

O objetivo deste trabalho foi mapear o uso da terra do Bioma Cerrado na escala de 1:250.000. As seguintes classes de uso da terra foram consideradas: culturas agrícolas, pastagens cultivadas, reflorestamentos, áreas urbanas e áreas de mineração. A metodologia envolveu a segmentação de imagens do satélite Landsat, a classificação visual dos segmentos e a análise da exatidão global do mapa final. Aproximadamente 39,5% do Cerrado apresentaram algum tipo de uso de terra. Pastagens cultivadas e culturas agrícolas foram as classes predominantes, com 26,5 e 10,5%, respectivamente.

Deforestation control in Mato Grosso: a new model for slowing the loss of Brazil's Amazon forest.

Philip M Fearnside (2003)

Controlling deforestation in Brazil's Amazon region has long been illusive despite repeated efforts of government authorities to slow the process. From 1997 to 2000, deforestation rates in Brazil's 9-state "Legal Amazon" region continually crept upward. Now, a licensing and enforcement program for clearing by large farmers and ranchers in the state of Mato Grosso appears to be having an effect. The deforestation rate in Mato Grosso was already beginning to slacken before initiation of the program in 1999, but examination of county-level data suggests that deforestation in already heavily cleared areas was falling due to lack of suitable uncleared land, while little-cleared areas were experiencing rapid deforestation. Following initiation of the program, the clearing rates declined in the recent frontiers. Areas with greater enforcement effort also appear to have experienced greater declines. Demonstration of government ability to enforce regulations and influence trends is important to domestic and international debates regarding use of avoided deforestation to mitigate global warming.
