Deforestation in Brazilian State of Rondônia

Brazil – June 14th, 2013

The conversion of tropical rain forests to pasture and cropland is having dramatic effects on the environment. Particularly intense and rapid deforestation is taking place in the state of Rondônia, Brazil, part of which is shown here.

About 30% (3,562,800 km2) of the world’s tropical forests are in Brazil. The estimated average deforestation rate from 1978 to 1988 was 15,000 km2 per year. In Rondônia, 67,764 km2 of rain forest had been cleared through 2003.

Systematic cutting of forest vegetation starts along roads and then fans out to create the “feather” or “fishbone” pattern, which begins to show in the eastern half of the 1986 image. The deforested land and urban areas appear lavender; healthy vegetation appears green (click here for more information).

Brazil – April 22nd, 2013

The state of Rondônia in western Brazil, once home to 208,000 square kilometers of forest (about 51.4 million acres), has become one of the most deforested parts of the Amazon. In the past three decades, clearing and degradation of the state’s forests have been rapid: 4,200 square kilometers cleared by 1978; 30,000 by 1988; and 53,300 by 1998. By 2003, an estimated 67,764 square kilometers of rainforest had been cleared.

In this image, intact forest is deep green, while cleared areas are tan (bare ground) or light green (crops, pasture, or occasionally, second-growth forest). Deforestation follows a fairly predictable pattern: the first clearings that appear in the forest are in a fishbone pattern, arrayed along the edges of roads. Over time, the fishbones collapse into a mixture of forest remnants, cleared areas, and settlements.

Fires Continue to Blaze in Brazil

Brazil – August 29th, 2012

Fires continue to blaze across Brazil, burning land in the states of Rondônia, Mato Grosso and Amazonas (click here for previous images). These fires are likely agricultural, set by farmers to clear land for crops, and may be contributing to problems of deforestation in the region.

Bolivia and Peru – August 29th, 2012

Multiple plumes of smoke from fires in Bolivia (lower right quadrant) and the Brazilian states of Rondônia (upper right) and Amazonas (above center) can be seen across this view of South America (click here for previous images). The plumes of smoke in Bolivia are blowing due northwest, while those in Brazil are fanning out over a larger area, although still being carried in a generally northwesterly direction. Visible across the Andes Mountains in the lower left quadrant is Lake Titicaca, on the border of Bolivia and Peru.

Brazil – August 26th, 2012

Fires are burning across central Brazil. Here, the upper half of the image is covered by a veil of smoke intermingled with popcorn clouds, while multiple individual blazes can be spotted in a horizontal line across the middle of the image. The fires are located near the borders of the states of Amazonas, Pará, Mato Grosso and Rondônia (clockwise from upper left quadrant). The plumes of smoke they are emitting blow in a generally westerly direction.
