Résumé
Cattle ranching has long been important to the rural inhabitants of North America. Much research has been conducted on this form of animal agriculture in the discipline of range science, but the spatial aspects of cattle ranching remain neglected. Private cattle ranching in the state of Sonora, Mexico, provides insight into the changing dynamics and spatial importance of ranching in North America. The ranching system in Sonora is characterized by large landholdings, family dynasties, and still-developing range management technologies. Private ranchers have often been viewed in the social science literature as a monolithic class of landowners, who manage in the same way, and persecute communal farmers and ranchers in similar ways. On the contrary, this dissertation suggests that ranchers occupy a continuum of sizes, motivations and political-economic abilities. One of the principal findings of this work is that, much like cultivation agriculture, smaller ranchers spend more time on land management. Larger ranchers must spend more capital to maintain a larger ranch infrastructure. The diversity of rangelands, and land management strategies, is also reflected in the biophysical landscapes of Sonora. Smaller ranchers tend to herd more animals on less land, and larger ranches consequently have better environmental conditions, such as land cover percentage and less soil compaction. Smaller and medium ranch owners also depend more heavily on their wives to run a ranching household—and female ranchers are also an important presence within the study area of Sonora. Long-term futures for ranching are in doubt because of climatic and economic factors contributing to the decline of smaller and medium-sized ranches
