A Shrinking Aral Sea
The Aral Sea in Central Asia began disappearing in the 1960s because of the diversion of its two feeder rivers for agriculture. This series of images illustrates unintended consequences of water management decisions. From left to right, the images were produced in 1977, 1998 and 2010.
International Borders: Mexico and Guatemala
In 1988, the first publicized Landsat image of the Mexico-Guatemala border showed clear-cut forest in Mexico and untouched trees in Guatemala. This image had a profound impact on the leaders of the two nations and influenced the establishment in 1990 of Guatemala's Maya Biosphere Reserve and other management and conservation efforts in Central America. Here is the original 1988 image of the border produced by Tom Sever and shown to the leaders of Mexico and Guatemala. The western portion is from Landsat 4 as seen on May 20, 1988, and the eastern part is from Landsat 5 on April 14, 1986.
