The Araguaia River and Protected Areas in the Brazilian Amazon11.6S 50.6W
The Araguaia River, visible as a vertical tan line on the right side of this image, is one of the major rivers of Brazil, and the principal tributary of the Tocantins. It has a total length of approximately 2,627 km.
Along its course, the river forms the border between the Brazilian federal states of Goiás, Mato Grosso, Tocantins and Pará. Here, most of the land visible is in Mato Grosso, west of the river, and Tocantins, east of the river.
The dark green and brown land around the Araguaia is a protected area for indigenous peoples, part of the Parque Indigena do Araguaia. On the far left, the dark green area of rainforest is also a protected national park, the Parque Nacional Xingu.
The parks were created with the twin objectives of protecting the environment and the indigenous populations of the area.
The land in the center of the image, however, is not protected and has been deforested and exploited for agriculture and grazing.
