An irrigation canal near the US Mexico border. In the Yuma Valley hardly any water flows in the old watercourse of the Colorado River, almost all has been diverted to provide water for cities like Las Vegas and Los Angeles, or irrigation water further upstream. Economic development and increased agricultural water use in the USA increased degradation of water quality received by Mexico. Sonoran Desert, Arizona. - David Bacon - 2010-12-04
