Agriculture and ranching have had a significant impact on the history and environment of the western United States. In popular culture, ranching is viewed both as a romantic representation of our western, pioneer heritage and as a symbol of environmental destruction. This course examines how modern agriculture and ranching fits with these perceptions by developing an understanding of what has been termed "conservation ranching." We will review how agriculture is practiced in the Southwest and the relationship between agriculture and sustainable land use. The focus is on ranching because it is the predominant land use in rural Arizona and other western states, but we will touch on sustainable farming practices throughout the semester.
