Little Colorado River Watershed (Arizona –USA)

On the Colorado Plateau farming has been an unbroken cultural tradition for at least 4200 years. The Navajo, Zuni, Apache, Hopi, Paiute and Tewa have cultivated the most diverse annual crop assemblage in the New World north of the Tropic of Cancer. The landscapes of this ecologically diverse but arid region have been shaped by a variety of traditional land and water use practices. Farmers have managed the same fields and terrace gardens for centuries, in a way well adapted to the arid climate and the altitudes from 3350 to 4000 meters. Their traditional ecological knowledge has been transmitted orally in at least six indigenous and three European languages. In addition to tending pre-Columbian crops, residents adopted and further adapted some sheep herding, ranching and orchard keeping traditions of Hispanic, Basque and Anglo immigrants. More recently, these rural communities have developed a multicultural food system with extensive cross cultural exchange and mutual support.
