Tribal agriculture contributed $753.3 million in total economic output and directly supported more than 2,300 jobs statewide in 2022, according to a first-of-its-kind analysis examining the economic footprint of Arizona's 22 federally recognized tribes using data from the most recent agricultural census.

The report, "Tribal Agriculture in Arizona: An Economic Contribution Analysis" was conducted by Cooperative Extension economic analysts in the University of Arizona College of Agriculture, Life, and Environmental Sciences and was supported by the Indian Land Tenure Foundation and the Native American Agriculture Fund.

Arizona's Indigenous communities have practiced agriculture for thousands of years, developing farming systems grounded in traditional ecological knowledge, water management and biodiversity. These practices remain central to tribal economies, cultural identity and food sovereignty today, yet the overall economic contribution of tribal agriculture across the state has received little study.

Estimating tribal agricultural activity is difficult because federal datasets often do not align with tribal boundaries, many reservations span multiple states, and privacy protections limit detailed reporting in sparsely populated areas, according to Dari Duval, corresponding author on the report and an Extension economist in the School of Natural Resources and the Environment. 

"We have always known that tribal agriculture is a huge share of Arizona agriculture in terms of the number of producers, the amount of land that these operations manage, and it has sort of an outsized effect on the state-level numbers," Duval said.

Tribal agricultural activity was estimated by the research team using the USDA Census of Agriculture, Reservation Census, and Navajo Nation Census, supplemented with USDA CropScape satellite data and supporting Extension and institutional reports. These sources provide a baseline estimate and the report is meant to provide a starting point for future analyses in partnership with tribal communities.

Key economic findings

The analysis revealed American Indians operate 62% of all farms in Arizona and manage 20 million acres, or 81% of the state's total agricultural land. 

While numerous, many operations are categorized as "small-scale," with 67% of American Indian farms falling in between 1 and 9 acres in size.  

Despite that, on-farm sales from tribal agriculture totaled $434 million in 2022, with crop production accounting for $410 million and livestock production contributing $23.9 million. 

American Indian farms also account for 95% of all sheep and goat farms and 71% of vegetable and melon farms in the state. 

"People don't always connect the dots and there's this perception that tribal communities aren't impacting our economic bottom line in the state," said Michael Kotutwa Johnson, a coauthor on the study and assistant professor and Cooperative Extension specialist of Indigenous resilience. "But this report, for the first time, can really point to that bottom line."

The report debunks the idea that tribal agriculture is an isolated sector. It found that 85% of economic multiplier effects generated by tribal agriculture actually "spill over" into non-tribal areas of the state. 

Maricopa County was the largest beneficiary, receiving $203 million in economic output from tribal agricultural activities in 2022, followed by Yuma County with $31 million and Pima County at $18 million. 

This activity supported 1,670 jobs outside of tribal lands in sectors such as wholesale nondurables – like food distributors, fuel, and farm supplies – and ag support services, according to the report.

Beyond the commercial data, the report also uncovers a significant "hidden economy" through the first-of-its-kind quantification of home production for home consumption, or food and livestock raised to feed families and communities that never enters formal market channels.

"It's challenging to provide a good, defensible metric for the value of home consumption in tribal communities, particularly in food deserts where a grocery store isn't around the corner," said Trent Teegerstrom, manager for tribal engagement with the Cooperative Extension.

The report notes that while many tribal operations may appear to have production expenses that exceed their market sales, these figures fail to account for the essential role this food plays in food security and cultural continuity. 

"If it doesn't enter the market channels, we don't really get to count it as sales but that agricultural production has value, it's contributing to food security, to food sovereignty and cultural resilience," Duval said.

Working from both supply and demand ends of the economic spectrum, the research team estimated the production value of this hidden economy within tribal communities at $116 million. On a per-capita basis, this translates to as much as $1,120 in grocery retail value per person in tribal areas. 

"These are healthy foods, nutrient dense foods. You can't really put a price tag on that," Kotutwa said. "The social impact, in my mind, is 10 times greater than the economic impact."   

This production is a continuation of practices that have existed "since time immemorial" and represents a direct investment back into the community, according to Kotutwa. "It's neighbor-to-neighbor. It's community."

Systemic barriers

Despite managing 81% of Arizona's agricultural land, American Indian producers face steep systemic hurdles that limit their access to federal support, according to Kotutwa. 

The report identifies a stark disparity in federal funding, with tribal farms receiving just 16% of total federal agricultural payouts in the state in 2022. 

While tribal producers account for a substantial share of farms receiving support, roughly 75%, their average payment is about $3,800 per farm receiving payment and remains far below the $63,600 average for non-tribal operations. 

A primary driver of this economic gap is the complex nature of land tenure and "jurisdictional fragmentation on reservation lands," Kotutwa explained. Much of the land is "fractionated," meaning a single parcel of allotted land can have over 100 heirs due to historical probate issues. As a result, securing federal conservation grants or leases often requires signatures from every individual owner, creating a bureaucratic bottleneck that makes it "very difficult to actually get anything done," he said.

The 'digital divide'

The report also highlights a significant "digital divide," with only 10% of American Indian farms in Arizona having access to broadband, compared to 39% of non-tribal farms. This lack of connectivity not only creates barriers to applying for federal grants and payments, but also limits adoption of precision agriculture technologies such as GPS-guided machinery, drones and soil mapping that may help improve productivity. 

Beyond land and infrastructure, Kotutwa and Duval both point to water as a defining factor in the future of Arizona agriculture, noting that tribal nations hold critical water rights but continue to face infrastructure and investment gaps that limit their full potential. 

"It begs the question, what would be possible if the tribes had full access to their water resources, their water rights, or allocations?" Duval said. "It speaks to historical disadvantages and lack of investment, but it also speaks to potential."
