These images show the progression of deforestation in Bolivia from 1986 to 2000. This area lies northeast of Santa Cruz de la Sierra, Bolivia, in an area of tropical dry forest. Since the mid-1980s, the resettlement of people from the Altiplano (the Andean high plains) and a large agricultural development effort (the Tierras Baja project) has led to this area's deforestation. The pie or radial patterned fields (upper left) are part of the San Javier resettlement scheme. At the center of each unit is a small community. The rectangular, light purple areas are fields of soybeans cultivated for export. The dark green strips running through the fields are windbreaks, which help prevent wind erosion of the area's fine soils. Landsat 5 25th Anniversary Imagery Collection: 30 by 30 meters (98 feet by 98 feet) spatial resolution. Researchers can identify objects slightly larger than the size of a baseball diamond. Path 230, Row 72: July 2, 1986 and June 22, 2000.
