A recent article in the scientific journal Annals of Botany presents new evidence that researchers have identified untouched species of agave plants once cultivated by various early societies, including the Hohokam people. The Hohokam were a prominent Native American community in the Southwest, existing from 300 to 1500 CE.
For approximately 9,000 years, agave plants have held significant economic and social value in the Americas. Prior to the cultivation of maize, these plants served as a primary source of carbohydrates. Archaeological studies suggest that the Hohokam people enhanced agricultural output by constructing terraces dedicated to the dry farming of agave. Specific agricultural structures like terraces and piles of rocks were notably prevalent in the farming techniques of this culture, particularly as population density increased.
While many crops originating from the Americas such as maize, peanuts, and potatoes have gained global prominence, nearly all have undergone substantial modification by European settlers and their successors.
Modern Investigations and Rediscoveries
Beginning in the 1980s and running parallel to archaeological endeavors, researchers from the Desert Botanical Garden have persistently cataloged and examined agave species across Arizona, the greater Southwest, and northern Mexico. This work led to the rediscovery and taxonomic classification of five out of the six recognized species of agave that are relics of the plants domesticated by pre-contact civilizations in present-day Arizona: Agave murpheyi, Agave delamateri, Agave phillipsiana, Agave sanpedroensis, Agave verdensis, and Agave yavapaiensis. Although once cultivated extensively, certain clones of these agaves have managed to survive for centuries within ancient, artificially constructed fields, ranging from southern Arizona to the Grand Canyon in the current landscape.
These ancient domesticated agaves demonstrate morphological features that distinguish them from both wild agaves of the Southwest U.S. and northern Mexico, and from wild and domesticated species in Mesoamerica. The residual clones offer a unique chance to study plant varieties that have remained virtually the same since their prehistoric cultivation.
The Importance and Preservation of These Agave Species
The scientists involved in this research argue that safeguarding these newly identified agave species is especially pertinent in today’s world, given rising attention and investigation into the extant wild relatives of modern crops. This is increasingly important for plants that thrive in arid, warm climates, as climate change has made such species more appealing for agricultural exploitation.
Wendy Hodgson, the lead author of the paper, stated, “We aim for our research to deepen our comprehension of present-day ecosystems as the outcome of historical human activities, rather than as untouched natural habitats. The people before European contact were highly skilled farmers who were adept at selecting, domesticating, and growing crops in the arid Southwest. The unique opportunity we have today to study the kinds of agaves cultivated by ancient farmers is particularly relevant in a time when there is a compelling need to examine the advantages of cultivating drought-resistant crops using sustainable agricultural practices.”

Frequently Asked Questions (FAQs) about Ancient Agave Cultivation in Arizona
What is the primary focus of the research published in Annals of Botany?
The primary focus of the research is the discovery of ancient, unaltered species of agave plants that were cultivated by early civilizations, including the Hohokam people in Arizona. The study emphasizes the significance of these plants for sustainable agriculture, especially in the context of climate change.
Who were the Hohokam people and what is their relevance to the study?
The Hohokam people were a prominent Native American community that existed in the Southwest from 300 to 1500 CE. Their relevance to the study lies in their cultivation techniques for agave plants, as well as the structures like terraces they built for agave dry farming, which were especially characteristic of their culture’s agricultural practices.
How long have agave plants been significant in the Americas?
Agave plants have held significant economic and social value in the Americas for approximately 9,000 years. Before the cultivation of maize, these plants served as a primary source of carbohydrates for early civilizations.
What has been the impact of European settlers on native American crops?
European settlers and their descendants have extensively modified almost all crops that originated from the Americas, such as maize, peanuts, potatoes, and tomatoes.
Who carried out the modern explorations and rediscoveries of agave species?
Researchers from the Desert Botanical Garden have been documenting and studying agave species since the 1980s. Their work led to the rediscovery and naming of five out of the six known species of agave that were domesticated by pre-contact peoples in today’s Arizona.
What distinguishes the pre-contact domesticated agaves from other agave species?
The pre-contact domesticated agaves are morphologically distinct from wild agaves found in the Southwest U.S. and northern Mexico, as well as from wild and domesticated species in Mesoamerica.
What is the modern significance of these ancient agave species?
The modern significance lies in their potential for sustainable agriculture, especially in arid and hot environments affected by climate change. Researchers believe that protecting these ancient agave species could be key to developing new agricultural strategies.
What does lead author Wendy Hodgson say about the study?
Wendy Hodgson states that the research aims to deepen our understanding of modern ecosystems as the result of historical human activities. She emphasizes that the pre-contact peoples were adept agriculturists and that studying these ancient agaves could be particularly relevant today, as there is a compelling need to explore the benefits of cultivating drought-resistant crops using sustainable methods.

Interesting article for sure. makes you think about how much we’ve modified crops since ancient times. What are we losin in the process?
Agave is more than just for tequila huh? This is really groundbreaking stuff, and kinda gives you hope for the future of farming.
Wow, this is truly eye-opening! Never knew agave had such a long history and it’s awesome to see how it’s being studied for sustainable agriculture today.
Honestly its so cool to think these plants have been around almost unchanged since pre-contact times. Like, what other secrets are they hiding?
Im impressed by how these ancient farming methods might be relevant in todays climate change scenario. Need more studies like this.
The Hohokam people seem really ahead of their time. Building terraces for agave dry farming? Thats some advanced stuff for an ancient civilization!
Are we finally realizing that ancient cultures had the right idea all along? Hats off to Wendy Hodgson and her team.
