Tucson is located in the Sonoran Desert, 117 km north of the US-Mexico border. The borderland region is an area experiencing increased temperatures and changing precipitation patterns caused by the combustion of greenhouse gases. Planting drought-tolerant trees to provide cooling shade has been an important mitigation strategy for Tucson and other arid cities. From 2007 to 2013, the Sonora Environmental Research Institute, Inc. (SERI) collaborated with Trees for Tucson (TFT) to distribute drought-resistant trees to low income families in south metropolitan Tucson.
