The March of Empire: The Californian Quest for Avocados in Early-Twentieth Century Mexico

ABSTRACTAt the turn of the twentieth century, agricultural explorers from the United States Department of Agriculture, Californian farmers, and the University of California scientists created the agricultural giant that California is today by extracting plant diversity from the Global South and protecting the nascent agricultural industry from outside competition. I define this process as “U.S. agricultural imperialism.” This article analyzes how U.S. agricultural imperialism in early-twentieth-century Latin America gave rise to a lucrative avocado industry closely associated with the Californian landscapes and agricultural identity and disconnected the fruit from its biological and cultural origins in Mexico and Central America to protect local production. U.S. institutions, growers, and scientists developed a thriving industry in the Golden State based on the extraction of avocado germplasm from Latin America while simultaneously banning the introduction of actual Mexican avocados to avoid outside competition.KEYWORDS: Avocadoplant-breedingexplorersCaliforniaagricultural imperialism AcknowledgmentsI wish to show my appreciation to the scholars and students of the UC Davis Latin American History Workshop for their generous feedback in the early stages of writing this article. I would also like to thank Dr. Erika Rappaport, Dr. Jeffrey Pilcher, and Elizabeth Schmidt for helping me finalize the project and the anonymous readers’ gen erous comments. Their suggestions significantly enriched this piece.

Olmstead and Rhode, Creating Abundance, 223.2. Although it is unclear how the term “alligator pear” was used in the first place, scholars believe it was because of the fruit’s shell resemblance with the alligator’s skin and the avocado shape of a pear. In 1941, the American Pomological Society and the USDA approved the term “avocado” as the translation to the Náhuatl-origin word ahuácatl (aguacate in Spanish).3.

The diversity of avocado strains in California at the turn of the twentieth century was not exclusive to this fruit. Californian nurseries imported different kinds of trees, like oranges, grapevines, pears, and apples, from abroad in vast numbers. Steve Stoll mentions that “between 1810 and 1942, approximately 570 species and varieties of trees -not shrubs, bulbs, vines, or flowers, but trees alone -entered California. Species and varieties of vines imported during the same period numbered 260,” in Stoll, “Insects and Institutions,” 217.16.

Her research interests focus on the many forms in which the transnational movement of people, food commodities, and agricultural technologies change rural landscapes in Latin America. Currently, Dr. Hernández is working on her first book project, “Guacamole Ecosystems: Agriculture, Migration, and Deforestation in Twentieth-Century Mexico,” which challenges the assumption that bureaucrats, scientists, and large-scale farmers were the primary actors in a long path of transformations of the Mexican countryside in the twentieth century.
