Indigenous Lands Help Protect Amazon Forests, Study Finds Reserve areas established for Indian peoples in Brazil (map) are as effective as uninhabited nature parks in preventing burning and clear-cutting, the study finds. ... The scientists used satellite data taken from 1997 to 2000 to compare rates of fire and deforestation inside and outside the boundaries of different reserve types. Only protected areas larger than 25,000 acres (10,100 hectares) were included in the analysis. ... "Many indigenous groups are very well organized, and they are also willing to use force to defend their lands," said Daniel Nepstad of the Woods Hole Research Center in Falmouth, Massachusetts, who led the study.
