Salta Province, Argentina
1989
2019
In northern Argentina’s Salta province, the chaco forests, made up of shrubs and hardwood trees, once thrived in the region. In the past 30 years, large-scale farming and ranch operators have cleared broad areas of the chaco, and replaced with industrial-scale raising of crops and livestock. The December 1, 1989 Landsat TM image is dominiated by traditional puestos, settlements consisting of a few dwellings and small-scale crops located near a well. The November 19, 2019 ASTER image shows large fields arranged in a grid pattern. The chaco forest has almost disappeared. The images cover an area of 22.2 by 27.8 km, and are located at 24.9 degrees south, 63.5 degrees west.
